Welcome to the April/May 2007 edition of MicroController Pros Corporation's Embedded News Digest, your source for microcontroller and embedded system news.
This month's issue:
Adeneo announced a strategic partnership with NXP around LPC MCUs.
The first joint action linked to this partnership is the development of the reference Windows Embedded CE 6.0 BSPs for the LPC3000 family of MCUs. A preview of this development has been revealed by NXP and Adeneo, running on a phyCORE LPC3180 module from PHYTEC. The first commercial release will also support the next LPC3000 family member.
Adeneo will provide a binary evaluation version at no cost, for testing and demonstration purposes. For OEMs wishing to use Windows Embedded CE and LPC3000 in commercial designs, Adeneo will provide complete source code through an attractive one-time license, without royalties.
The BSPs includes drivers for most of the peripherals integrated in LPC3xxx chips. This allows targeting all types of custom solutions. The BSPs are qualified using the Windows Embedded CE official test kit, and have been designed to take full advantage of the advanced features of the LPC3xxx such as Advanced Power Management for both idle and suspend modes.
Based on the AVR32 uC core, the UC3A Series has 512K bytes Flash and features an embedded 10/100 Ethernet MAC, a full-speed (12 Mbps) USB 2.0 with On-The-Go (OTG) capability and an SRAM/SDRAM external bus interface. The AT32UC3A0512 and AT32UC3A1512, the first devices available, deliver 80 Dhrystone MIPS (DMIPS) at 66 MHz and consume only 40 mA at 3.3V.
The AVR32 UC core uses a three-stage pipeline Harvard architecture specially designed to optimize instruction fetches from on-chip Flash memory. It is the first core in the industry to integrate single-cycle read/write SRAM with a direct interface to the CPU that bypasses the system bus to achieve faster execution, cycle determinism and lower power consumption. The AVR32 UC core shares the same instruction set architecture (ISA) as its AVR32 AP parent, with over 220 modeless instructions available as 16-bit compact and 32-bit extended instructions. The ISA features atomic bit manipulation to control on-chip peripherals and general-purpose IOs, and fixed-point DSP arithmetic such as single cycle fractional saturated multiply-and-accumulate. An event-handling system supports events such as prioritized interrupts, non-maskable interrupt and internal exceptions with a maximum interrupt latency of 16 clock cycles.
The AVR32 UC3A Series incorporates many of the same peripherals as Atmel's ARM-based MCUs including the peripheral DMA controller, multi-layer high-speed bus architecture, 10-bit ADC, two SPIs, SSC, two-wire interface (I2C compatible), four UARTs, three general-purpose timers, seven pulse width modulators and a full set of supervisory functions.
The 10/100-Mbps IEEE 802.3-compliant Ethernet (MAC) allows designing networked embedded systems that communicate over internet protocol stacks. The USB 2.0 full speed (12Mbps) interface provides a means to communicate with today's PC architecture through various USB classes such as HID for serial data communication or Mass-Storage for larger bulked data transfers. The On-The-Go (OTG) capability of the UC3A USB peripheral gives further integration opportunity in a PC-centric environment with the support of standard USB devices such as USB Flash disk, pointing devices or printers.
The external bus interface (EBI) extends the addressable physical memory to 16M bytes. Its non-multiplexed 16-bit data bus can interface to high density external SRAM, SDRAM, ROM, Flash devices and memory-mapped devices such as LCDs or FPGAs.
UC3A Series MCUs have a six-layer high-speed bus matrix that enables busmaster peripherals to concurrently access any bus slave at a maximum speed of 264M bytes per second at 66 MHz. The bus masters are the AVR32 UC core data and instruction interfaces, 15-channel peripheral DMA controller, and several high-speed peripherals such as the Ethernet MAC and USB. The bus slaves are the on-chip SRAM and Flash memories, USB, the two peripheral bus bridges, and the external bus interface (EBI).
Atmel provides the GNU gcc C compiler, GNU gdb debugger, FreeRTOS.org real-time kernel and lwIP TCP/IP protocol stack for the UC3A Series family, free of charge. Commercial licenses from IAR (Embedded Workbench), ExpressLogic (ThreadX) and Micrium (uCOS/II) are also available. Atmel's AVR32 Studio and AVR JTAGICE mkII provide the AVR32 UC with a multiplatform integrated development environment (IDE) already configured for the GNU tool chain, including support for more advanced debugging such as real-time trace. The EVK1100 evaluation kit provides Ethernet and USB interfaces, along with many other serial communications ports such as SPI, TWI and USARTS. A 20x4 character LCD and the expansion connector allow advanced product evaluation and prototyping activities.
The AT32UC3A0512 (with EBI) is available in a 144-pin QFP package, and the AT32UC3A1512 (without EBI) is available in a 100-pin QFP package. Pricing starts at US $8.16 and US $7.43 for 10,000 unit quantities, respectively.
Atmel Corporation announced the CAP microcontroller-based system-on-chip (SoC) platform for complex applications that require fast time-to-market. CAP features high-speed local memory, a wide range of industry-standard peripherals and interfaces, and a high-capacity metal programmable (MP) block that allows the designer to add a significant amount of custom logic on-chip. By leveraging the architecture of Atmel's AT91SAM microcontrollers, the new CAP metal programmable microcontroller platform enables application-specific products to be developed in a fraction of the time and at a fraction of the cost of a conventional standard-cell or gate array ASIC, but at a unit price close to that of standard-cell devices. Stocks of CAP platforms are held prior to metal layer fabrication, allowing prototypes to be delivered rapidly, and accelerating volume production.
CAP is based on Atmel's Metal Programmable Cell Fabric (MPCF) that provides nearly identical routed gate densities to those of standard cells in the same process. The initial CAP product introduction comprises the AT91CAP9S series, based on the ARM926EJ-S processor.
The AT91CAP9S offers a 200 MHz ARM926EJ-S core with 16 KBytes each of program and data cache, 32 KBytes of additional SRAM, 32 KBytes of ROM, EBI with error correction code (ECC) for NAND Flash/SmartMedia and 250K or 500K metal programmable gates. Peripherals include both a USB full-speed host and USB 2.0 high-speed device, 10/100 Ethernet MAC, image sensor interface, 2.0A and 2.0B CAN controller, LCD controller, MCI, SSC, PWM, LCD and AC97 controllers, SPI master and slave, two USARTs, three 16-bit timer counters, an 8-channel, 10-bit analog-to-digital converter, and a full complement of supervisory functions. Optional hardware AES/TDES encryption/decryption engines are also included. The AT91CAP9S is built around a multi-layered bus and a distributed DMA architecture for the high internal data bandwidth required by deeply embedded networked applications.
Dual-core architectures can be created by instantiating an additional ARM core, Atmel's proprietary AVR processor or a DSP core in the MP Block. Bus master controls are brought into the MP Block, and DMA access can be provided to the system bus.
The AT91CAP9-DK development board implements the fixed portion of the CAP device as a microcontroller standard product, tightly coupled to a high-density FPGA that emulates the MP Block. The boards also include a range of memories and physical interfaces/connectors representing external system components. This configuration enables parallel hardware/software testing of the application under development at close to operational speed, with no penalty for hardware modifications. This enables software development to proceed in parallel with hardware development, and significantly reduces the design cycle time, increasing confidence in a right-first-time system solution.
Atmel's CAP products are supported by the same third-party development tools as Atmel's standard product AT91SAM ARM-based MCUs, including C/C++ compilers, in-circuit emulators and debuggers, from third-party suppliers. AT91CAP9S is able to host Microsoft Windows CE and Linux, and a number of proprietary real-time operating systems. This extensive software support network simplifies the task of application development.
CAP NRE starts at $150K, to cover netlist implementation/placement & routing in the Metal Programmable Block, mask costs, fabrication, testing and delivery of prototypes. AT91CAP9S is priced at $13 in volumes of 100K units. AT91CAP9S products and development boards are available now.

It will combine the excellent code efficiency of the M16C and R32C CPUs with the high-speed data processing of the H8S and H8SX CPUs. Moreover, the new CPU architecture will further extend the low power consumption and low noise characteristics of both family lines.
By employing this new architecture, Renesas aims to reduce code size by 30% and CPU power dissipation by 50%.
Renesas announced the SuperH Family SH7775, an SoC solution designed for high-performance car information systems such as next-generation car navigation systems. Sample shipments will begin in July 2007 in Japan.
The SH-4A CPU core used in the SH7775 features a 600MHz operating frequency and high processing of over 1 GIPS. The integrated floating-point processing unit (FPU) also has a maximum operating frequency of 600 MHz. The FPU supports single-precision and double-precision operations, and offers computational performance of up to 4.2 GFLOPS in single-precision mode.
The SH7775 also incorporates a graphics engine optimized for functions related to map drawing. In addition to 2-D drawing functions such as bold-line drawing and anti-aliasing, it implements 3-D drawing functions such as triangle 3-D drawing and texture mapping. This makes it possible to render high-quality map images rapidly, which is a key function of car navigation systems. A wide variety of 3-D objects, such as buildings and landmarks, can be rendered as part of the map imagery. A single drawing engine can handle drawing of elements essential to the display of the car navigation system, including maps, icons, and menus.
To enable developers to exploit the full performance potential of the graphics engine, Renesas Technology will offer MAPGL Graphics Software Engine. This software package has a convenient API (Application Programming Interface) that makes it easy to utilize the drawing functions supported by the graphics engine for rendering map images. It also provides a PC simulation environment that recreates the results of rendering on an actual system to support the development of new graphics applications.
To further reduce the CPU load, both graphics engines also include a geometry engine that performs such tasks as vertex coordinate calculation. Drawing processing performance is up to three times that of the SH7770 due to the high operating speed of 150 MHz combined with improvements to the rendering method. The result is smooth, high-image-quality 2-D and 3-D graphic display.
The SH7775 also implements a rich variety of peripheral functions necessary for car information systems. The peripheral modules include a GPS baseband processing function, an ATAPI interface, a USB v2.0 host/function interface, a CAN in-vehicle LAN interface, multiple sound interfaces, and multiple serial interfaces.
In addition, the use of a Unified Memory Architecture enables memory to be shared by each modules, making it possible to reduce the number of external memory parts.
The external buses provided are a 32-bit dedicated bus enabling connection to high-speed DDR2-SDRAM (Double Data Rate 2-Synchronous DRAM) and a 32-bit extension bus for connection to flash memory or SRAM.
The package used is a 560-pin BGA (25 mm x 25 mm).
An E10A-USB emulator connected to a host PC via a USB interface can be used as a development environment, and the provision of an on-chip debugging function allows real-time debugging to be carried out at the maximum operating frequency.
A user system development reference platform offering the following features is also available, enabling the user to carry out efficient system development.
STMicroelectronics complemented its ST7 UltraLite family of tiny 8-pin microcontrollers with the introduction of the ST7FLITEU0 series. Its availability in 8-pin SO, DIP and 0.9mm-thick DFN packages, with temperature qualification up to 125 degrees C, makes the new series an ideal choice for HVAC, home appliance, lighting control and power-tool markets.
With a 2-Kbyte Flash program memory, twice as large as previous devices, and 128 bytes of data EEPROM, the new tiny devices have a significantly larger software capacity. In addition, they include a trimmable 8MHz RC oscillator, with prescaler ratios down to 500kHz, and a very stable and accurate Low-Voltage and Auxiliary Voltage Detector.
The very small 8-pin MCUs target simple motor drives and include features such as an embedded 12-bit auto-reload timer, operating over a 2kHz to 4MHz range, which can generate four independent PWM (Pulse Width Modulated) signals, with output compare function. The timer also includes programmable Dead Time generation for the half-bridge driving mode in which PWM signals must not be allowed to overlap, plus programmable duty cycles, polarity control and programmable output modes.
Other key system peripherals are an 8-bit Lite timer with prescaler, watchdog, real-time base and input capture; and a very fast, 5-channel, 10-bit ADC with 3.5 microsecond overall conversion time. Five power-saving modes -- Halt, Auto Wake-Up from Halt, Active Halt, Wait and Slow -- offer the designer very high flexibility to minimize the overall power consumption in power-critical applications.
Samples of the 8-pin ST7FLITEU0 are available now in SO8, DIP8, DFN8 and DIP16 (for sampling only) packages, with the development tools; volume production will start during Q2 2007. Pricing for 10,000 units starts at US$0.55.
Texas Instruments has announced volume availability of TMS320F28044 and F2809 digital signal controllers.
TI's TMS320C2000 controller platform's now includes 18 high-performance, 32-bit controllers that combine real-time DSP performance with the peripheral integration, C-language efficiency and ease of use of a microcontroller (MCU). F28044 and F2809 devices feature a 32-bit wide data path for superior performance and mixed 16/32-bit instruction set for improved code density. These devices also feature a patent-pending PWM with 150ps resolution. This unprecedented high-resolution pulse width modulation (HRPWM) technology provides 16 bits of accuracy in a 100 KHz control loop and 12 bits at 1.5 MHz.
The TMS320F28044 (sampling announced in October 2006) is the industry's only single, programmable controller that can manage up to 16 DC/DC converter channels for multi-phase control. Each channel offers 150ps resolution and is based on patented HRPWM technology. The controller's programmability lets designers build intelligence into power supply systems and simultaneously manage sequencing, margining, phase compensation, and transient response of multiple DC/DC converters. DSP performance plus integrated HRPWM technology provides the full digital loop control and output accuracy necessary at switching frequencies over 1MHz.
The F28044 controller is part of TI's growing DSC and high-performance analog portfolio of digital power solutions that enable designers to implement digitally controlled power systems with high system intelligence and performance in an easy-to-use, intuitive development environment. TI's digital power solutions are optimized for applications ranging from point-of-load to high-power AC/DC and DC/AC conversion.
At $5.00 in volume, the F28044 device provides full digital loop control and system management for only $0.32 per channel. Because one F28044 device performs all loop control, sequencing, system management and communications for up to 16 DC rails, designers save costs by eliminating individual analog converters, standalone sequencing chips and communications MCUs previously used in complex POL applications.
The F2809 controller offers exceptional system integration, providing complete control system capabilities from signal input through the on-chip analog to digital converter (ADC), quadrature encoder pulse (QEP), and timer captures and compares through signal output with up to 16 independent PWM channels. The 12.5 megasamples per second (MSPS), 12-bit ADC boasts an effective number of bits (ENOB) of 10.9 and is valid across the full -40 to 125 °C temperature range. Key communication interfaces include multiple CAN, I2C, UART and SPI ports. The F2809 device offers 256KB of on-chip Flash, 36KB and includes six 150ps resolution PWM channels. The F2809 controller is available for $13.00 in 1,000-unit quantities.
Texas Instruments has announced the sampling of its 16 MHz MSP430F47x4 ultra-low power MCUs for one- and multi-phase metering. By integrating up to four individual 16-bit sigma-delta analog-to-digital converters, a 32x32-bit hardware multiplier, a 160 segment LCD driver with contrast control, up to 60 KB of Flash memory and a real-time clock, the F47x4 devices enable a five-to-one reduction in system components.
With standby power consumption as low as 1.5 micro amps, a meter based on these new devices allow utilities to drastically reduce overall system power wastage. The F47x4 series of MCUs features several low-power modes allowing the meter to sleep with almost no power drain between readings. An extremely fast wake-up brings the device to full clock speed within six microseconds; together with a fast shut-down, this "instant-on" wake-up minimizes time spent in active mode.
TI offers a broad portfolio of components to enable AMR-based electricity, water and gas metering. MSP430 MCUs provide ultra-low power consumption needed to extend battery life -- over 12 years -- eliminating costly ongoing meter service calls for battery replacement. The already available MSP430FE42xx series of devices includes an embedded signal processing (ESP) unit that integrates the metering function -- including current and voltage measurement and power calculations, for faster system development and reduced BOM. TI also offers dedicated solutions including a single-chip flow meter, the available MSP430FW42xx MCU, which features an embedded scan interface optimized for measuring rotation and AMR interface.
TI's Chipcon radio frequency (RF) technology, such as the CC1100, enables a wireless link between the meter and the meter reader. This increases reading accuracy while lowering collection costs.
PLC offers utilities access to meter control and data over existing high power lines over distances up to 50 kilometers for robust performance in a variety of control and monitoring applications in industrial and other rugged environments. TI's 32-bit TMS320F28x digital signal controllers offer the performance and high integration required for data communications rates of up to 19.2 kbps in the in the sub-500KHz frequency range, ideal for metering applications.
The MSP430F47x4 series of MCUs will be available for sampling in June through local TI sales offices. In volume, the devices will start at $7.50 per 1K quantities. TMS320F28x digital signal controllers and Chipcon RF devices are available in volume and start at $3.25 and $0.99, respectively.
