The AT91SAM9G20 is based on the ARM926EJ-S processor, with a clock speed of 400MHz. It features 32K byte instruction and 32K byte data cache memories, two 16K-byte blocks of SRAM and 64K bytes of ROM with single cycle access at maximum processor or bus speed, together with an external bus interface with controllers for SDRAM and static memories including NAND Flash and CompactFlash. The AT91SAM9G20 is a pin-compatible evolution of the AT91SAM9260, offering four times the cache and on-chip SRAM memory of its predecessor, and features improved error correction for external NAND Flash as well as an enlarged Ethernet FIFO that improves latency. Achieving half the power consumption at twice the clock frequency of the AT91SAM9260, it consumes only 80 mW in full-power mode with all peripherals turned on. 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.

Boardcon Kit9G20 Evaluation Board takes full features of the processor By providing a complete set of common system peripherals, minimizing overall system costs and eliminating the need to configure additional componentsand. It supports 64MByte SDRAM and 256MByte NAND Flash as well as 2 USB2.0 Host and 2 SD Card function. The board has exposed many other hardware interfaces including up to 7 RS232 serial ports, Ethernet, Extension connector and JTAG. KIT9G20 comes with the Linux open-source operating system and the U-Boot boot loader pre-installed. Linux offers all the functionalities of a modern operating system. Multitasking, virtual memory management and dynamically loaded libraries make Linux ideal for many fields of application.Because of its open source code, Linux is well-documented.A variety of programs and tools are available for free in the Internet. Additionally, the OS core can be customized anytime to meet your individual needs.
