This month's issue:
Atmel Corporation has announced the AT91SAM9260, the first
member of a pin-compatible ARM9-based microcontroller family that shares the
same programming model as ARM7-based controllers, allowing direct migration
between controllers based on different ARM cores. The AT91SAM9260 also supports
deterministic, real-time operation, offers supervisory functions, and has
third-party RTOS support comparable to those of 8-bit controllers.
Developed for highly-connected image-processing applications such as
point-of-sale terminals, Ethernet-based IP cameras, and bar code readers, the
AT91SAM9260 integrates a 200 MIPS ARM926EJ-S core with: a camera interface;
seven USARTs; 10/100 Ethernet MAC; 12 Mbps USB device and host controller with
on-chip transceivers; external bus interface supporting SDRAM, Flash, NAND Flash
with built-in ECC, SD, SDIO, and Multimedia Card interface (MMC); three
synchronous serial controllers (SSC); two master/slave Serial Peripheral
Interfaces (SPI); a three-channel 16-bit timer/counter; two-wire interface (TWI);
and IEEE 1149.1 JTAG Boundary Scan on all digital pins.
The internal bus bandwidth of the AT91SAM9260 is maximized by 24 DMA channels
and a five-layer high-speed bus matrix. It connects all masters and slaves in
the system in a parallel fashion and enables data transfers between peripherals
and on- and off-chip memories without any CPU intervention. A programmable
arbiter manages the priorities between the bus masters. Highly critical
interrupt routines can be locked in the 16 kByte instruction cache, guaranteeing
a deterministic response time to interrupts. A system controller provides a full
complement of supervisory functions that includes an 8-level priority interrupt
controller, RC-oscillator, PLLs, real-time periodic interval and watchdog
timers, reset and shutdown controllers, and backup registers. The shutdown
controller puts the processor in an ultra-low power mode, typically less than 10
Atmel's SAM9 microcontrollers are the first ARM9-based microcontrollers with
Flash memory integrated on the same chip.
The AT91SAM9260 has third-party RTOS support from Green Hills Software, Mentor
Graphics and Micrium. Compiler/debuggers are available from Green Hills
Software, ARM, Keil, IAR Systems and any compliant ARM926EJ-S compiler. Windows
CE and Linux operating system support is also provided.
The AT91SAM9260 is available now in a 217-ball LFBGA RoHS-compliant package and
in a 208-pin Green QFP package, and is priced at or near $6 in quantities of
100,000. Additional members of the SAM9 family will be available in late 2006
Microchip Technology has announced a family of 16-bit dsPIC Digital Signal
Controllers (DSCs) for common, multi-loop switch-mode power supplies (SMPSs) and
other power-conversion applications.
The PWM on the dsPIC30F1010 and dsPIC30F202X devices offers 1 ns duty cycle
resolution and seven modes of operation, including standard, complementary,
push-pull and variable-phase. The 10-bit A/D converter has up to 12 input
channels and samples at up to 2 MSPS. Advanced sampling capabilities include
individual triggers for each of four sample and holds, and precise, uniquely
timed or simultaneous sampling.
The dsPIC30F1010 devices have 6 Kbytes of Flash and two PWM generators, and the
dsPIC30F202X have 12 Kbytes of Flash and four PWM generators. All devices in
this family operate between 3.0 and 5.5 volts. Additional features include:
Onboard high-speed analog comparators (2 or 4); 30 MIPS performance at 5.0
volts; small footprint QFN package (6 mm x 6 mm); fast, deterministic response;
extended temperature operation (-40 to 125 degrees Celsius); and optional PWM
dither mode for Electromagnetic Interference (EMI) reduction.
The dsPIC30F1010 and dsPIC30F202X DSCs are supported by the MPLAB Integrated
Development Environment (IDE), MPLAB C30 C Compiler, MPLAB SIM 30 Software
Simulator, MPLAB ICD 2 In-Circuit Debugger and MPLAB Visual Device Initializer.
The dsPIC30F1010 is available in 28-pin SOIC, SPDIP and QFN packages; the
dsPIC30F2020 in 28-pin SOIC, SPDIP and QFN packages; and the dsPIC30F2023 in
44-pin TQFP and QFN packages. These DSCs start at $2.99 each in 10,000-unit
quantities. General sampling is expected in July, and volume production is
expected in August.
Renesas Technology has announced a total of five SH7263 and SH7203
high-performance microcontroller models with a 200 MHz maximum operating
frequency, incorporating a SuperH Family SH2A-FPU CPU core and a Host interface
supporting the USB (Universal Serial Bus) standard v2.0 High Speed
The SH7263 and SH7203 incorporate a high-performance SH2A-FPU CPU core with a
built-in FPU, and operate at a maximum frequency of 200 MHz. Operation at the
maximum operating frequency of 200 MHz provides high-speed processing power of
480 MIPS and 400 MFLOPS, representing an approximately 70% increase in signal
processing performance over the current 120 MHz SH7261 incorporating the same
These microcontrollers also incorporate a variety of interfaces and peripheral
functions necessary for configuring a digital audio device, including a Host and
Function interface supporting the USB2.0 High Speed specification, and a display
controller capable of bit-mapped display on liquid crystal panels up to WVGA
Like the current SH7261, the SH7263 also incorporates such functions as an audio
CD-ROM decoder, a serial sound interface (SSI) for input and output of digital
audio data, a serial communication interface with a 16-stage FIFO, and an I2C
bus interface. Also included are a sampling rate converter that converts the
audio data sampling frequency, and functions necessary for a digital audio
device, which contribute to a significant reduction in system costs.
The SH7263 and SH7203 incorporate an external data bus expandable up to 32 bits,
allowing direct connection to Flash ROM, SDRAM, SRAM, and so forth, without the
use of external parts.
Other on-chip functions include a 5-channel multifunction timer unit suitable
for motor control, capable of 3-phase PWM wave output for AC motor control, as
well as an 8-channel 10-bit A/D converter, 2-channel 8-bit D/A converter,
8-channel DMAC, CAN controller, and NAND Flash controller. These varied
peripheral functions enable the number of external parts to be reduced, and make
it possible to create a high-performance system at lower cost.
The SH7263 includes a model with a combination of an SD memory card interface
and an IEBus controller channel for control communications, offering a selection
of models suited to various user system specifications.
The package used is a 240-pin QFP. Sample shipments will begin in July 2006 in
On-chip debugging functions are also provided that enable real-time debugging to
be carried out at the maximum operating frequency.
MP3, WMA, AAC, or similar voice compression standard compatible middleware
enables a multi-CODEC-capable system to be implemented by software, while
software including a CD-ROM ISO9660 file system and HDD FAT32 file system is
also available, providing software solutions for digital audio product
Texas Instruments has added four new low-cost members to the TMS320F280xx
digital signal controller series targeted at motor control, digital power
conversion and intelligent sensor control applications. The new TMS320F28015 and
F28016 controllers offer 60 MHz of performance starting as low as $3.25 (in
1000-unit quantities), while the new TMS320F2801-60 and F2802-60 controllers
also offer 60 MHz of performance and are based on the current TMS320F2801 and
F2802 devices. TI is also announcing a new digital power development kit, which
consists of a TMS320C2000 Digital Power Supply (DPS) software library and a
series of hardware modules from Tier Electronics that provide off-the-shelf
platforms that engineers can control with this software library.
TI's F280xx controllers offer a portfolio of 11 pin-for-pin- and
software-compatible devices with 32-bit DSP performance combined with the
peripheral integration and ease-of-use of an MCU. All F280x-based devices
feature a 32-bit wide data path for superior performance and mixed 16/32-bit
instruction set for improved code density. These controllers provide complete
control system capabilities, from signal input -- through the on-chip, 12-bit
ADC, QEP interfaces, and timer capture/compares -- through signal output with up
to 10 independent PWM channels. Depending on the device, communication
interfaces include CAN, I2C, UART and SPI ports.
All four new F280x devices feature a patent-pending pulse width modulator (PWM)
with 150 picosecond (ps) resolution. The high resolution PWM (HRPWM) provides 16
bits of accuracy in a 100 KHz control loop and 12 bits at 1.5 MHz. As a result,
power developers will benefit from designs with cleaner power output, higher
power density, smaller magnetics and more compact, cooler supplies. These
benefits are critical in applications like AC/DC rectifiers that require high
tolerances and faster transient response with small ripple amplitude. For motor
control applications such white goods and automotive, designers can reduce
overall system costs through integration and low device cost, while leveraging
the 32-bit performance necessary to implement advanced control techniques like
sensor less vector control of three-phase motors. Using processor-intensive
sensor less vector control can help developers to reduce the size and cost of a
system's motors and power electronics required to meet their needs.
The TMS320F2801-60 and TMS320F3202-60 are available now. The TMS320F28015 and
TMS320F28016 are expected in October. All four new controllers are AEC Q100
automotive qualified in 100-pin LQFP packaging.
