Atmel has developed a new 400 MHz ARM926EJ-S based embedded microprocessor that draws only 80 mW in full-power mode with all peripherals turned on. The AT91SAM9G20, pin-compatible with the 200 MHz AT91SAM9260, 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. It is targeted at power-constrained applications that also need high performance, such as point-of-sale terminals, building automation, security cameras and bar code readers.
The AT91SAM9G20 offers a choice of operating systems, with support for Microsoft Windows CE, .NET MF and Linux, as well as a number of realtime operating systems and middleware products from third parties including Adeneo, IAR, Keil, Mentor Graphics, Micrium, Segger and TimeSys.
Networking and communications requirements are met by 12 Mbps USB Full Speed Dual Host and Device ports, an Ethernet 10/100 Base T MAC, four USARTs, SPI, SSC and two-wire interface (TWI). The image sensing requirements of many target applications are met by a fully integrated image sensor interface (ISI).
In addition to halving the power consumption in full-speed operating mode (where the clock frequency is software programmable), the AT91SAM9G20 features four reduced-power modes, including Backup Mode where the main power supply is off and the device power consumption drops to 9 mW for an extended period of operation under battery supply.
