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.

The AT91SAM9G20 is targeted at power-constrained applications that also need high performance. These include point-of-sale terminals, building automation, security cameras and bar code readers.

The AT91SAM9G20 supports Microsoft Windows CE, .NET MF and Linux, as well as a number of real-time operating systems (RTOS) and middleware products from industry-leading third parties including Adeneo, IAR, Keil, Mentor Graphics, Micrium, Segger and TimeSys.

The AT91SAM9G20 leverages Atmel's peripheral DMA (direct memory access) and distributed memory architecture that, together with the 6-layer bus matrix, enables multiple simultaneous data transfers between memories, peripherals and external interfaces without consuming CPU clock cycles. The external bus interface (EBI) is clocked at 133 MHz for high-speed transfers to off-chip memories. This architecture gives the device the high internal and external data bandwidth required by many embedded networked applications.
