1. Description
Based on the ARM926EJ-S core, the SAM9G25 is an embedded microprocessor unit, running
at 400 MHz and featuring connectivity peripherals, a high data bandwidth architecture and a
small footprint package option, making it an optimized solution for industrial applications.
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 con-
nection to the ITU-R BT. 601/656 8-bit mode compliant sensors and up to 12-bit 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 10-bit ADC.
The External Bus Interface incorporates controllers offering support for 8-bank DDR2/LPDDR,
SDRAM/LPSDRAM, static memories, as well as specific circuitry for MLC/SLC NAND Flash with
integrated ECC up to 24 bits.
The SAM9G25 is available in a 217-ball BGA package with 0.8mm ball pitch, as well as a 247-
ball BGA package with 0.5mm ball pitch, making it ideally suited for space-constrained
applications.
