Embedded Chip Consumes Only 80mW

( 1 Jul 2008 )


Atmel Corp.'s 400MHz AT91SAM9G20 ARM926EJ-S-based embedded microprocessor draws only 80mW in full-power mode with all peripherals turned on. Pin-compatible with the 200MHz AT91SAM9260, the AT91SAM9G20 offers four times the cache and on-chip SRAM memory and features improved error correction for external NAND Flash as well as an enlarged Ethernet FIFO that improves latency. The chip is targeted at power-constrained applications that also need high performance, including bar code readers, POS terminals, and security cameras. Featuring peripheral DMA, distributed memory architecture, and six-layer bus matrix, the device enables multiple simultaneous data transfers between memories, peripherals and external interfaces without consuming CPU clock cycles.

The AT91SAM9G20 support Microsoft Windows CE, .NET MF and Linux, as well as RTOS and middleware products from Adeneo, IAR, Keil, Mentor Graphics, Micrium, Segger and TimeSys. The AT91SAM9G20 features four reduced-power modes, including Backup Mode, where the main power supply is off and the device power consumption is sufficiently low (9µW) for an extended period of operation under battery supply.
