Chip Introduction


A high-performance ARM926-based embedded microprocessor unit, running at 400MHz and featuring multiple networking/connectivity peripherals, including two 2.0A/B compatible Controller Area Network (CAN) interfaces and two IEEE Std 802.3-compatible 10/100Mbps Ethernet MACs. Additional communication interfaces include a soft modem, HS USB Device and Host, FS USB Host, two HS SDCard/SDIO/MMC interfaces, USARTs, SPIs, I2S, multiple TWIs and 10-bit ADC. The SAM9X25 offers a multi-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 SDRAM/LPSDRAM, DDR2/LPDDR and specific circuitry for MLC/SLC NAND Flash with integrated ECC. The SAM9X25 is available in a 217-ball BGA package with 0.8mm ball pitch.
