The Embest MBC-SAM9G20 Core Board, measuring 45mm x 52mm, is a very small size, low power consumption but high performance arm9 based processor board. It is based on an ATMEL AT91SAM9G20 ARM926EJ-S core based microprocessor, with 64KB ROM and 16KB SRAM on-chip memories. The board features a Micro USB port, a Debug UART port, a 5V power port and comprehensive external memories: 4MB DataFlash,256MB NandFlash,64KB EEPROM and 64MB SDRAM. It is so tiny that it can reduce much space of your products. You can use it easily to complete your project development and save much of your time to the market.

| Development Reference |
| |
| General |
| This core board is an ARM9 minimum system to start learning and developing an ARM9 application, it is also an idea ARM9 card to integrate into your product. It extended most of the signals of AT91SAM9G20 processor to an interface (QSH-060-01-L-D-A). And it can be used to evaluate your application base on one of the mother board (part# MBM-SAM-9G), which is led out most signals of ATMEL AT91SAM9G20, like UART, Ethernet, LCD, Touch Screen, USB Host, USB Device, ADC, DAC, SPI, SDIO, GPIOs and so on. |
