Atmel Introduces Three New picoPower AVR MCUs

Atmel  has announced three new "picoPower" AVR microcontrollers . The picoPower technology reduces "power-save" power consumption to as little as 650 nA, even with the 32 kHz clock running. Never mind that even at 1.8V this actually translates into microWatts, not "picoWatts" as the name would imply - only a factor of 1 000 000 difference. How's that for creative marketing stretching the truth "just a bit".

The three picoPower devices now available are the ATmega164P, ATmega324P and ATmega644P 44-pin general-purpose microcontrollers. All three microcontrollers are pin- and feature-compatible, differing only in the size of Flash, EEPROM and SRAM memory. ATmega164P has 16 KB of self-programmable Flash memory, whereas the ATmega324P and ATmega644P have 32 KB and 64 KB, respectively. All three devices feature a 10-bit ADC, two USARTs, SPI and Two-Wire-Interface, and operate from 1.8 to 5.5 volts with up to 20 MIPS throughput.

AVR picoPower microcontrollers consume as little as 340 uA in active mode, 650 nA in power-save mode with real time counter (RTC), and 100 nA in power-down mode. They will be pin-, performance- and code-compatible with existing AVR microcontrollers.

Atmel's picoPower technology utilizes a variety of techniques that eliminate unnecessary power consumption in power-down modes. These include an ultra-low-power 32 kHz crystal oscillator, automatic disabling and re-enabling of brown-out detection (BOD) circuitry during sleep modes, a power reduction register (PRR) that completely powers down individual peripherals, and Digital Input Disable registers that turn off the digital inputs to specific pins.

The ATmega164P and ATmega324P in 40-pin PDIP, 44-pin TQFP and 44-pin QFN packages are available now for sampling. Production quantities will be available in Q4 2006. Volume prices for 10,000 units are $2.23 for ATmega164P and $2.78 forATtiny324P respectively. The ATmega644P will be available for sampling in Q1 2007 and production quantities in Q2 2007. Volume prices for 10,000 units will be $3.72.

Crossware Adds CAN Controller Simulation to ARM Development Suite

Crossware has enhanced its ARM Development Suite to enable simulation of CAN controller peripherals of LPC2119, LPC2129 and LPC2194 microcontrollers from NXP Semiconductors (formerly Philips Semiconductors).

The Crossware ARM Development Suite simulates all aspects of a CAN controller and generates a stream of output bits. This bit stream is transferred to a simulated CAN bus where it is merged with the bit streams of other simulated CAN controllers. The merged bit stream is reflected back to all CAN controllers, allowing each to win or lose arbitration, transmit and receive data, provide a signal acknowledgment or error status, etc.

The Crossware Code Creation Wizards will create code for the CAN controllers as well as for the acceptance filter, message identifiers, message data, etc. Using these wizards, the code to transmit a message and receive a message can be generated in minutes without a single line of code having to be written manually. The program then can be built, and seconds later the developer can see the transmitted message appearing on the simulating CAN bus and being received and acknowledged by the receiver.

The Crossware suite is simple and easy to use, and abstracts the developer from the complexity of the CAN bus code. The graphical interfaces of both the simulating CAN controller and the simulating CAN bus provides visual verification which is both useful as proof of activity and for educational purposes.

The LPC2119, LPC2129 and LPC2194 chips, based upon the ARM7TDMI-S processor core, feature multiple CAN controllers, so it is possible to transmit messages between these CAN controllers via the CAN bus. It is also possible to run multiple simulations on multiple PCs as they can connect to the simulating CAN bus across the LAN and thus exchange messages with each other.

The CAN bus application itself allows 'components' to be connected to the bus. These components automatically will respond as receivers but can be configured to transmit predefined messages, and to respond to specific received messages. No coding is required, making it easy to set up a complete simulating CAN system.

By default, the CAN bus application simulates a single bus. However, it can be configured easily to support additional buses. One CAN controller of a simulating ARM chip can then connect to one bus while another connects to a different bus. This allows the software for a CAN hub to be tested without any hardware.

The CAN bus is becoming popular with embedded developers due to its speed, reliability and price/performance, and it is particularly well suited to embedded network applications where high-speed communication between multiple microcontrollers is required.

The Crossware ARM Development Suite provides a complete and extremely user-friendly development environment for the ARM family of microprocessor cores with its advanced C compiler, libraries, wizards, simulator and debugger.

Freescale Introduces S08 MCUs with ADC and 5V Operation

Freescale is introducing a new member of its 8-bit S08 MCU family, designed to reduce board space, system cost and power consumption for small appliance and DC fan applications.

The MC9S08QD4 (QD4) integrates a four-channel, 10-bit analog-to-digital controller (ADC) and an automatic compare function.  The automatic compare functionality allows the MCU to compute values and perform comparisons to a preset threshold.

The QD4 also includes an internal clock source (ICS) module containing a frequency-locked loop (FLL) controlled by internal or external reference. The internal reference clock can eliminate the cost of all external clock components, which helps reduce board space and enhances system reliability. Other features of the MC9S08QD4 include a 16MHz HCS08 CPU, HC08 instruction set with added background instruction, 4KB Flash memory, 256B RAM, and dual 16-bit on-chip timers. It is available in 8-pin PDIP and 8-pin SOIC packages.

The QD4 is pin-compatible with the ultra-low-end MC9RS08KA2 and the highly integrated MC9S08QG8 microcontrollers. Shared peripherals and a common set of development tools help make it quick and easy for engineers to leverage their design investments.

Samples of the MC9S08QD4 are available now in production quantities. Suggested resale pricing for 10,000-piece quantities is 69 cents (USD).

Freescale Introduces Four New Digital Signal Controllers

Freescale Semiconductor is adding four digital signal controllers to its 16-bit 56F8000 DSC family.

The latest 56F8000 DSCs are available in four lead-free package options, ranging from 32 to 64 pins, with Flash memory sizes from 12KB to 64KB. Other additions to the 56F8000 peripheral set include a digital-to-analog converter (DAC) and analog comparators. An optional Multi-Scalable Controller Area Network (MSCAN) 2.0 A/B module is available on the higher memory devices, providing robust connectivity for industrial and automotive applications.

Recent regulatory requirements are driving appliance manufacturers to increase the system integrity/safety of their control circuitry. The 56F8000 family addresses these latest regulations with advanced features, such as an independently clocked watchdog timer and the capability to verify Flash memory contents. Both features allow system designers to guard against conditions such as code runaway that could potentially induce unsafe conditions in their end products.

Product specifications and development systems for the 56F8037, 56F8036, 56F8025 and 56F8023 DSC devices are available now. Production quantities are planned for the Q1 2007.

The ability to operate from either 3.3V or 5V gives maximum flexibility in electrically noisy environments without additional costs.

The peripheral set of the STR7 range is further enhanced in the STR750 family by new features including a backup clock that starts operating if the main clock fails, a fast startup capability that allows the device to begin executing code in only 55μs instead of the 1ms typically required for devices using a quartz crystal, an Automatic Wake Up (AWU) capability that removes the need for external signals or components to wake up from low-power STOP or STANDBY modes, and three flexible and powerful 16-bit timers and a PWM timer that includes 3-phase motor control features that simplify the implementation of complex motor control including vector control drive applications. Serial communications include up to three high-speed (2Mb/s) UARTs with support for the LIN protocol, and a serial memory interface for glueless connection to external serial Flash memory. Moreover, the STR750 family also includes new mechanisms to allow bit manipulation and masks to protect I/O pins.

The initial family comprises 30 different derivatives, with from 64K up to 256KB of Flash plus an additional 16K bank of Read-While-Write Flash for EEPROM emulation. The embedded Flash memory offers excellent retention characteristics, with data retention guaranteed up to 20 years at 85°C. Devices include up to eight communication peripherals including USB and CAN, as well as a 4-channel DMA controller that significantly reduces CPU loading and a fast 10-bit ADC. Some members of the new family are specified over an extended temperature range of -40°C to +105°C.

The enhanced security features of the STR750F family, such as the backup clock, make these new devices particularly suitable for alarm system control panels, motor control, data loggers, modem, printers/scanners, vending machines, and a wide range of other embedded applications.

The devices are available in TQFP64 /BGA64 and TQFP100/BGA100 packages. Prices for 10,000-unit quantities range from $3.60 each for the STR755FR0T6 (64K Flash, 64-pin package) to $6.50 each for the STR750FV2T6 (256K Flash, 100 pins, USB, CAN).

Toshiba Develops New 8-bit Microcontroller Core

Toshiba Corporation has developed a new 8-bit microcontroller core, designated TLCS-870/C1. This new core is capable of processing one instruction cycle in a single clock cycle, enabling faster processing at lower frequencies, reduced noise and lower power consumption compared with Toshiba's previous 8-bit core. Its large-capacity address space is expandable to 128 Kbytes.

The core architecture was modified from the previous TLCS-870/C architecture to achieve the fast processing of one instruction cycle in a single clock cycle. The result was up to a four-fold increase in performance at the same clock frequency, compared with existing Toshiba 8-bit MCUs.

Part of the IC design used synchronous RTL design instead of multiphase-clock design based on circuit diagrams.

The TLCS-870/C1 core is binary compatible with previous Toshiba 8-bit MCUs; thus, existing software resources can be used.

Toshiba anticipates releasing devices based on the new core later this year.
