Atmel: Four New Microcontrollers for Lighting Ballast Applications

Atmel has released four new microcontrollers meant for different types of lighting ballast applications, including single and multiple fluorescent tube applications, systems with DALI control, and HID lighting such as back-projection display systems or vehicle headlamps.

The AT90PWMx AVR microcontrollers support the dimming fluorescent and the HID ballast segments. Both the 8-Kbyte Flash AT90PWM3 and AT90PWM2 devices integrate the DALI protocol, allowing you to network the ballasts to a centralized system, thus achieving high flexibility in controlling light levels, plus maintenance benefits and high energy savings. The 4-Kbyte Flash AT90PWM1 offers a cost-effective solution for low-end HID lamp ballasts and dimmable fluorescent lamp requiring an analog control interface.

For the non-dimming fluorescent ballasts, the AT83EB5114 is a highly integrated and optimized C51 microcontroller. Available in a low-pin-count SO20 package, it supports a 4-Kbyte ROM and a 256-byte EEPROM.

These microcontrollers have dedicated peripherals to manage both the Power Factor Correction (PFC) functionality and the lamp power, thus reducing the external component count. These functionalities are ensured by 12- or 16-bit enhanced PWM generators, amplifiers, and a 10-bit Analog-to-Digital Converter. The AT90PWM3 also integrates a 10-bit Digital-to-Analog Converter.

The AT90PWM2 is available in SO24; the AT90PWM3 is available in SO32 or MLF/QFN32. Pricing for 10,000 units is $2.20 for the AT90PWM2 and $2.50 for the AT90PWM3. The AT90PWM1 samples will be available in 3Q05 in SO24 package. Users can start designs on the AT90PWM2, as it offers compatibility with the AT90PWM1. The AT83EB5114 ROM device is available in SO20 package for large volumes at a unit price of $1.30. A Flash version (AT89EB5114) in SO20 is also available for development purpose.

Atmel: CANopen Protocol Stack for AT91SAM7A ARM7-based Microcontrollers

Atmel Corporation and Port GmbH have released an industrial-strength CANopen Protocol Stack for the Atmel AT91SAM7A ARM7-based microcontroller family.

The CANopen Protocol Stack is fully compliant with the CiA standard DS301 V4.02. It may be used to implement network master, slave or mixed applications, using more than one CAN channel for controlling the CANopen network. In addition to standardizing communication objects, CANopen specifies application objects used in various device profiles. These device profiles guarantee a defined device behavior and provide interchangeability of CANopen devices. Port GmbH provides extension modules for its CANopen Library to employ these profiles. The modules make it easy to use the desired device profiles. Beyond the generic profile for digital I/O devices, additional ones are available, including Safety-Relevant Communication, Layer Setting Services (LSS) or Flying Master for use in maritime applications.

Pricing of the CANopen Protocol Stack starts at €2500. Free Evaluation versions for Atmel's AT91SAM7A evaluation kits are available from Port.

Atmel: Three New tinyAVR Flash Microcontrollers with Internal Temperature Sensors

Atmel has announced three new members of the tinyAVR Flash Microcontroller family, targeting battery chargers, sensor end-points and low-end motor control applications.

The devices offer three different Flash, EEPROM and SRAM combinations. The ATtiny25, ATtiny45 and ATtiny85 have 2 KB, 4 KB and 8 KB of Self-Programmable Flash memory, respectively. They each include a temperature sensor, allowing temperature calibration of system parameters. Being truly pin compatible and functionally the same, it is possible to migrate both up and down in memory footprint with minimum effort. All the new devices are capable of 20 MIPS throughput when running at 20 MHz.

In embedded systems, the ATtiny25/45/85 can monitor and control temperature, power supply voltages and currents, and communicate to the system host through its Universal Serial Interface (USI) communication module.

All advanced microcontroller features that are typically found only in high-end microcontrollers are available in these small eight-pin microcontrollers, such as internal EEPROM, differential ADC channels, and integrated 16 MHz high-precision internal RC Oscillator.

The on-chip, low-power PLL is used to control two Pulse Width Modulation (PWM) outputs capable of generating a 250 kHz PWM output at 8-bit resolution. User-adjustable dead-time generators are used to avoid pulse overlapping for the driver stage. Together with the four 10-bit A/D converter channels, and a fast analog comparator, this provides all the means for current and voltage control and safety when controlling power.

ATtiny25/45/85 also excels in battery-powered equipment due to the inherent low power consumption, and three individually selectable low-power sleep modes. Also, the application software can control the system clock frequency in real time. Additional power saving is achieved by using the Power Stop System, allowing the user to turn off timers, USI, and/or ADC when not in use. The ATtiny25/45/85 consumes less than 100 nA in Power Down mode.

Samples of ATtiny45 are available today in PDIP or SOIC 8-pin packages, and QFN 20-pad packages. ATtiny25 and ATtiny85 samples will be available in 2Q05. Volume production will commence in 2nd half of 2005 for the three devices. Volume prices for 10,000 units are $0.80, $0.97 and $1.27, for ATtiny25, ATtiny45 and ATtiny85 respectively.

Atmel: ATmega406 Fully-Configurable Single-Chip Smart Battery Solution

The new ATmega406 is the first high-voltage technology AVR microcontroller implementing full 2- to 4-cell Lithium Ion smart battery monitoring and protection on a single chip.

To enable the ATmega406 to be powered directly from a 2-, 3- or 4-cell Li-ion configuration, the device includes an on-chip voltage regulator allowing the device to be powered from 4 to 25V. It also features three 25V-tolerant FET drivers for charge, discharge, and pre-charge, as well as on-chip FETs for cell balancing. To provide the most accurate estimate of charge left, the device has a Coulomb Counter ADC with an 18-bit output for battery current monitoring, as well as a 12-bit ADC for individual cell voltage and temperature monitoring. Both ADCs use high-accuracy on-chip voltage reference. Battery protection is autonomous, providing the end-user with the best safety, as MCU-related issues such as a code runaway or a software bug do not affect it. Adding communication periphery and an efficient MCU architecture, ATmega406 is the first fully configurable single-chip smart battery solution in the market.

Battery protection is implemented as independent circuitry, not requiring the MCU to operate. If the device is exposed to an over-current or short-circuit condition, the autonomous battery protection will shut off the affected FET. Likewise, if any cell voltage drops to a potentially damaging voltage level, ATmega406 will automatically prevent further battery discharge by shutting down the discharge FET and going to a power-off mode. Independent battery protection ensures the safest solution for the end user. The trigger levels for the different battery protection modes are programmable, and for safety reasons they are also lockable against software updates. If no battery protection is triggered, the MCU is allowed direct FET control, which enables battery-charging algorithms to be implemented inside the battery itself.

Balancing cell voltages effectively increases the amount of charge that can be drawn from the battery pack by aligning the lowest safe voltage of all battery cells. Individual battery cell monitoring combined with the ATmega406's integrated cell balancing FETs allow cell-balancing algorithms implemented in software to improve battery capacity.

With 40 Kbytes of Flash program memory, 512 Bytes of EEPROM for data parameter storage, and 2 Kbytes of internal SRAM for program data, ATmega406 has the algorithm processing power necessary to implement battery monitoring and management for a full 4-cell laptop PC battery pack configuration. The device includes the SM-bus interface for communication with the host application, and Atmel's self-programming Flash allows battery firmware upgrading through this or any other interface.

All parts of the ATmega406 are optimized for extremely low power consumption, drawing less than 1.2 mA in active mode and less than 2 µA in power-off mode.

The ATmega406 is available today in LQFP 48-pin package. Pricing starts at $2.75 for volumes above 100K.

Fujitsu: Two New 32-bit Flash Microcontrollers with up to 5 UARTs

The new microcontrollers capitalize on a powerful FR60 core running at up to 50MHz with a 5-stage pipeline, 16-bit fixed-length instruction set, and built-in hardware multiplier and barrel shifter. They were specifically designed for a wide range of embedded control applications including digital home appliances.

The devices incorporate an external bus for memory expansion or the direct connection of Graphic Display Controllers. They also integrate 512kByte of embedded Flash memory as well as 24kByte of embedded SRAM. The versatile external interface allows direct access to 16-bit SRAM as well as asynchronous ROM (Page Mode Flash supported). This, together with its high-speed 5-channel Direct Memory Access Controller (DMAC), guarantees fast data transfer and simplifies circuit board design.

Serial communication is supported by an I2C interface and up to five USARTs (each with their own baud rate generator). Four independent ICU (Input Capture Unit) channels are included together with up to eight OCU (Output Compare Unit) channels, four 16-bit reload timers and up to six PPG timers. A maximum 12 channels of 10-bit A/D converter as well as up to three channels of D/A converter complete this powerful data processing engine.

To enable maximum flexibility, if a resource function is not used the respective pin can be used as standard input or output pin.

A flexible clock concept offers several internal clock frequencies as well as individual settings for the core, the peripherals and the external bus interface. These, combined with the standard power management function assists the user in finding the optimum trade-off between performance and power consumption for specific applications.

Infineon Back in the 8-bit FLASH Microcontroller Market; New TriCore Micros

Other competitive features of the TC1115 include 144KByte of on-chip RAM memory, a 32-bit high-performance External Bus Unit (EBU) for fast access between caches and external memories, and Infineon’s Flexible Peripheral Interface bus (FPI) for enhanced on-chip communications. A capture and compare unit and a multifunction GPTU (General Purpose Timer Unit) enable flexible PWM signal generation. Like all TriCore-based microcontrollers, the TC1115 combines the real-time capability of a microcontroller, the math performance of a DSP and the simple programmability of the RISC architecture. The TC1115 features a dual voltage supply with 1.5V core and 3.3V I/O voltage.

The TC1796 is the latest member of the Infineon AUDO-NG family. It offers 150MHz system speed at full automotive temperature range, 2MByte embedded program flash and 128KByte data flash memory. The new 32-bit TriCore-based microcontroller is ideally suited for use in demanding automotive and industrial control applications that require real-time performance combined with DSP capabilities and very fast interrupt response times. Innovative peripherals like the Micro Second Bus, the Micro Link Interface for serial inter-processor communications and the advanced triple bus (local memory bus and two peripheral busses) structure make the TC1796 one of the most powerful 32-bit automotive microcontrollers. The 32-bit Peripheral Control Processor (PCP 2) with single-cycle instructions offloads tasks from the CPU and increases the overall computing performance.

The feature set of the TC1796 also includes two Asynchronous Serial Channels (ASC), two SSCs, a CAN module with four CAN nodes (MultiCAN) for high efficiency data handling, two GPTAs with a powerful set of digital signal filtering and timer functionality to realize autonomous and complex I/O management, a Local Timer Cell Array (LTCA) for signal generation purposes, two medium speed AD converter units with 8-bit, 10-bit or 12-bit resolution and a fast AD converter unit.

Micronas: New 8-bit/16-bit Microcontroller for Car Dashboard Applications

Micronas announced  a new 8/16 bit controller platform. Highly integrated, the CDC 16xxF family features three CAN interfaces, a Power Saving Module (PSM), five stepper motors drivers, five pulse-width modules, a sound generator, an integrated LCD module and many other peripherals. To simplify upgrades of existing designs, the device executes both legacy 8-bit code and 16-bit instructions, and it can address up to 256 KB of program memory without bank-switching.

Each of the three CAN modules can individually administer up to 16 objects, allowing for simple gateways putting only moderate load on the CPU. The CAN modules can be used as full- or basic CAN and meet the requirements of the Bosch specification V2.0B. The modules are ISO 16485 certified by C&S in Wolfenbüttel.

The ports can be used to drive LCD displays directly by means of the integrated LCD module. For instrumentation and steering column applications, the controller contains an audio module allowing the user to implement simple sounds such as chimes, buzzers, turn-signals clicks, and other warning or status alerts. Power management has been enhanced with two new modes, Idle and Wake, plus an integrated Real Time Clock (RTC) module for direct support of car clock operation, eliminating the need for an external 32 KHz oscillator.

Additional features are an interrupt controller, four different timers, a 9-channel 10-bit ADC, two comparators, three UARTs, two SPI ports, and a DMA controller. The built-in Patch Module allows easy changes to ROM-based code, even in the field. Any section of software can be patched and replaced with code stored in an external EEPROM device. The CDC 16xxF also features the patented EMI Reduction Module (ERM). ERM is a cost-saver; by reducing the need for external filtering components and reducing the number of PCB layers, the ERM alone saves 0.18 to 0.22 Euros per system.

The CDC 1607F is the master flash ROM device in Micronas' 8/16-bit car dashboard controller family. Based on the WDC65C816 CPU core, it features 256 KB of flash memory, 6 KB of SRAM and a 4 KB boot ROM.

The V850E2/ME3 microcontroller features the new V850E2 ™ CPU core that enables processing speeds of 400 million instructions per second (MIPS) at up to 200 megahertz (MHz), made possible by the V850E2 controller's superscalar architecture and seven-pipeline structure (upgraded from the five-pipeline structure previously used in the V850E1 ™ CPU core). The V850E2 microcontroller also enables 90 percent improvement in processing speed over previous versions with its simultaneous processing of two instructions sets using a single clock.

The 168-kilobyte (KB), high-speed instruction RAM, which is 40 KB more than the previous core, as well as an 8 KB instruction cache and 8 KB data cache, enable real-time processing of large data volumes, making the V850E2/ME3 microcontroller ideal for printers and other applications that require high performance.

The V850E2/ME3 device offers an extensive lineup of peripheral functions, including a full-speed USB 2.0 interface, and incorporates an SSCG (spread spectrum frequency synthesizer clock generator) function that can reduce the peak value of electromagnetic interference (EMI) noise by more than 10 decibels (dB).

Samples of the V850E2/ME3 microcontroller will be available March 1, 2005, at an expected price of US$22. Volume production is scheduled to begin during July 2005.

Philips: ARM9 family-based microcontrollers in 90nm

By utilizing 90nm process technology and the ARM926EJ-S™ core, Philips is able to reduce manufacturing costs, decrease power dissipation and increase operating speeds of its new LPC3000 microcontroller family.

The 90nm technology allows for 1V operation - reducing power dissipation nine times over 3V devices. The ARM9 family also provides several power management benefits including the ability to go into a low-power state until an interrupt or debug request occurs. Peripherals such as integrated USB On-the-Go (OTG) and full USB Open Host Controller Interface (OHCI) host capability eliminate the need for an external controller.

Philips' LPC3000 family products will operate at 200MHz and feature a large array of standard communication peripherals to reduce system logic, thus reducing power and costs. These include up to 7 UARTs, SPI, I2C, USB, real-time clock, the NAND Flash interface and others - such as Ethernet - to follow. The family also features a vector floating-point coprocessor for full support of single-precision and double-precision calculations at CPU clock speeds, which is important for signal processing applications such as motor control.

Samples of the first devices in Philips' LPC3000 family will be available in Q2 2005.

Renesas: Low-Pin-Count, Small-Package, 50 MHz High-Speed Operation SH Microcontrollers

Renesas announced a new series of low-pin-count small-package microcontrollers, the SH/Tiny Series, to its lineup in the SuperH™*1 family of 32-bit RISC (reduced instruction set computer) microcontrollers.

Renesas provides low-pin-count small-package microcontrollers as "Tiny Microcontroller" products and has released three series of these products: the H8/Tiny Series, the R8C/Tiny Series, and the M16C/Tiny Series. The SH/Tiny Series, which is now being added to the Renesas lineup, is the high-end series of the Tiny Microcontroller product line, and includes the 64-pin SH7125F (two models) and the 48-pin SH7124F (two models).

The SH7125 Series microcontroller incorporates the SH-2 32-bit CPU core, which features a maximum operating clock frequency of 50 MHz and achieves the high processing performance of 65 MIPS. Both the 64-pin version SH7125F and the 48-pin version SH7124F provide two kinds of on-chip flash memory capacity of 128K bytes or 64K bytes.

The multifunction timer pulse unit 2 (MTU2) can provide a 3-phase PWM output for use with inverter equipment. Since this MTU2 function can automatically start the motor current detection A/D converter with an arbitrary timing in synchronization with the carrier, it reduces CPU load and allows these devices to implement brushless DC motor one-shunt vector control*3. Furthermore, the 10-bit A/D converter features a conversion speed of 2.0 µs per channel. Since two A/D converters are included, up to two analog signals can be converted at the same time.

In addition, these microcontrollers provide functions for protecting power modules such as IGBT modules. If an external signal is input to the port output enable (POE) pin, the 3-phase PWM output can be set automatically to the high-impedance state (the electrically disconnected state) to prevent the power module from being damaged by over voltage.

These microcontrollers also provide a variety of other peripheral functions, including three serial communication interface channels and a watchdog timer. The SH7125 Series incorporate a built-in power supply step-down circuit and are designed for reduced current consumption.

Texas Instruments: Faster Version of TMS320C6412 DSP

Texas Instruments announced production-qualified samples of the TMS320C6412TM DSP, now running at 720 megahertz (MHz) and achieving 2,880 million 16-bit multiply-accumulate operations (MMACs) per second.

To further speed processing, the device also integrates generous on-chip random access memory (RAM), featuring 256 Kbytes in level 2 cache.

The 720 MHz version of TI´s TMS320C6412 DSP adds to the 500 and 600 MHz versions that are already in full production. Production-qualified samples of the 720 MHz C6412 DSP are available now, with volume production scheduled for 2Q05. Production order entry is open now for 720 MHz versions. C6412 pricing ranges from $37.95 for 500 MHz to $63.99 for 720 MHz, per unit in quantities of 10K units.

Texas Instruments: New 1 GHZ DSP Can Support Multiple 3G Wireless Standards

The new 1 GHz TMS320TCI6482 DSP performs at nearly twice the clock speed of other available solutions, yet consumes only three watts of power. Built on TI´s  90nm process, this new wireless infrastructure-optimized DSP offers several enhancements on the previous TMS320C64xTM-based products. The TCI6482 features 28 new DSP instructions that offer specific capabilities that enable more applications such as High Speed Download Packet Access (HSDPA). In addition, the TCI6482 is the first DSP to offer a serial Rapid I/OTM interconnect for scalable connectivity, higher system bandwidth, and reduced latency and overhead for packet data processing. 

With advanced communications peripherals like a Gigabit Ethernet Media Access Controller (MAC), the TCI6482 makes a good platform for evolving the media gateway to handle higher wireless codec channel densities.

ST Microelectronics: 10-MIPs 8-bit MCU with Full-Speed USB 2.0

The core of the uPSD3400 Turbo Plus series is a 4-cycle-per-instruction 40-MHz 8032 MCU. This high-performance core is further enhanced by the addition of an internal 16-bit path that allows 2-byte instructions to be fetched in a single memory cycle. The wider path coupled with a pre-fetch queue and branch cache brings average performance to 9 MIPS, with peak performance at 10 MIPS.

The uPSD3400 Turbo Plus series supports USB 2.0 at full-speed (12-Mbps). The USB provides 10 endpoint pairs (in/out), each with its own 64-byte FIFO including support for Control, Interrupt, and Bulk transfers.

A JTAG interface supports in-system programming and MCU core debug with high speed instruction tracing capability, eliminating the need for a hardware In-Circuit Emulator (ICE).

Based on ST's proprietary Programmable System Device (PSD) architecture, uPSD3400 devices feature dual independent banks of Flash memory, 8 kbytes of SRAM, and over 3000 gates of programmable logic with 16 macrocells. The dual-bank Flash architecture and programmable decode logic support true READ-while-WRITE concurrent access for In-Application Programming (IAP). Memory mapping is handled by an integrated decoding PLD that can assign any Flash or SRAM memory segment to any address on any memory page or bank. Additionally, Flash memory can be allocated to 8032-code space or data space in almost any proportion as needed, which is a feature unique to uPSD devices.

Other peripherals include a 16-bit Programmable Counter Array (PCA), an 8-channel 10-bit resolution analog-to-digital converter, SPI and IrDA interfaces, six PWM (pulse-width modulated) channels, an I2C (Intelligent Interface Controller) master/slave bus controller, two standard UARTs (Universal Asynchronous Receiver/Transmitter), supervisory functions such as a watchdog timer and low-voltage detect, and up to 45 general-purpose I/O pins.

Designers can use the 16-macrocell CPLD to replace external glue logic devices such as 22V10 PLDs, 20L8 PALs, and 74-series discrete logic ICs. Common functions forged from the CPLD array include state machines, shifters and counters, keypad and control panel interfaces, chip-selects for external devices, clock dividers, multiplexers, and handshake delay circuits.

uPSD3400 devices are sampling now with volume production planned for late 1Q 2005 in 52-pin and 80-pin TQFP packages, with industrial operating temperature -40C to +85C at 5.0V and 3.3V. Pricing starts at $4.00 in quantities of 10,000.
