DATASHEET

Description

Based on the ARM926EJ-S™ core, the Atmel® | SMART 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 connection 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 4-bank and 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 Atmel | SMART SAM9G25 is available in a 217-ball BGA package with 0.8 mm

ball pitch, as well as in 247-ball TFBGA and 247-ball VFBGA packages with 0.5 mm

ball pitch, making it ideally suited for space-constrained applications.
