SAM9X25
Atmel | SMART ARM-based Embedded MPU
DATASHEET Description
The SAM9X25 is a member of the Atmel ® | SMART series of 400 MHz
ARM926EJ-S™ embedded microprocessor units. This MPU features 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, as well as specific circuitry
for MLC/SLC NAND Flash with integrated ECC up to 24 bits.
The SAM9X25 is available in a 217-ball BGA package with 0.8 mm ball pitch. Atmel-11054F-ATARM-SAM9X25-Datasheet_31-Aug-15 Features Core
