The MBC-SAM9G25 is an ARM embedded core board which integrate the ATMEL ARM926EJ-S-based processor AT91SAM9G25. Based on the ARM926EJ-S core, the SAM9G25 is an embedded microprocessor unit, running at 400MHz and featuring connectivity peripherals, a high data bandwidth architecture. The multi layer bus matrix is linked to 2 x 8 DMA channels as well as DMAs dedicated to the communication and interface peripherals, ensuring uninterrupted data transfers with minimal processor overhead. Interface peripherals include a camera interface that supports direct connection to the ITU-R BT. 601/656 8bit mode compliant sensors and up to 12bit grayscale sensors. Communication peripherals include a soft modem supporting exclusively the Conexant SmartDAA line driver, HS (480 Mbps) USB host and device ports with on chip transceivers, FS USB host, 10/100 Ethernet MAC, two HS SDCard/SDIO/MMC interfaces, USARTs, SPIs, I2S, multiple TWIs and 10bit ADC.
