1. Description
The SAM9X25 is a high-performance ARM926-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 10/100Mbps Ethernet MACs. Additional communication inter-
faces 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 8-bank DDR2/LPDDR, SDRAM/LPS-
DRAM, static memories, and specific circuitry for MLC/SLC NAND Flash with integrated ECC.
The SAM9X25 is available in a 217-ball BGA package with 0.8mm ball pitch.
