AT91SAM9G45 CPU Board, Samtec Connector, MicroUSB, UART, 256MB US$120.00

C9G4
AT91SAM9G45 CPU Board, Samtec Connector, MicroUSB, UART, 256MB

The Embest MBC-SAM9G45 Core Board, measuring only 45 52 mm, is a processor board containing an Atmel AT91SAM9G45 processor that has a 400 MHz ARM926EJ-S core with 32 KBytes Data Cache, 32 KBytes Instruction Cache with MMU, 64KB ROM and 64KB SRAM on chip. The board also features a Micro-USB port, a Debug UART port, a 5V power port and comprehensive external memories: 4MB DataFlash, 256MB NandFlash, 64KB EEPROM and 128MB SDRAM. It is so tiny that it can reduce the size of your products.

Part of its space saving is achieved through its extension interface to a motherboard. This CPU module has a Samtec QSH-060-01-L-D-A connector for attaching to a system, providing 120 pins in a compact form factor. The matching connector that your system must have is the QTH-060-01-L-D-A.

Before designing your own motherboard, you might consider purchasing the M9G4, which includes this CPU module and a motherboard with all the CPU interfaces made available for immediate testing.

The CPU module comes with Linux 2.6 pre-installed. A CD-ROM is provided with WinCE6.0 BSP which you can install optionally. Source code of both Linux and WinCE packages and drivers are included as well. Android BSP can be downloaded at the bottom of this page.
