The SAM9X25 is a high-performance ARM926EJ-S™-based embedded
microprocessor unit, running at 400 MHz and featuring multiple networking/connectivity
peripherals, optimized for industrial applications such as building automation, gateways
and medical.     

The SAM9X25 features two 2.0A/B compatible Controller Area Network (CAN)
interfaces and two IEEE Std 802.3-compatible 10/100 Mbps Ethernet MACs. Additional
communication interfaces include a soft modem supporting exclusively the Conexant
SmartDAA line driver, HS USB Device and Host, FS USB Host, two HS
SDCard/SDIO/MMC interfaces, USARTs, SPIs, I2S, TWIs and 10-bit ADC. 

To ensure uninterrupted data transfer with minimum processor overhead, the
SAM9X25 offers a 10-layer bus matrix coupled with 2 x 8 central DMA channels and
dedicated DMAs for the high-speed connectivity peripherals. 

The External Bus Interface incorporates controllers for 4-bank and 8-bank
DDR2/LPDDR, SDRAM/LPSDRAM, static memories, and specific circuitry for
MLC/SLC NAND Flash with integrated ECC. 

The SAM9X25 is available in a 217-ball BGA package with 0.8 mm ball pitch.
