AT91SAM9XE Series
Atmel | SMART ARM-based Embedded MPU
DATASHEET
Description
The AT91SAM9XE series is based on the integration of an ARM926EJ-S™
processor with fast ROM, RAM and Flash, and a wide range of peripherals.
The embedded Flash memory can be programmed in-system via the JTAG-ICE
interface or via a parallel interface on a production programmer prior to mounting.
Built-in lock bits, a security bit and MMU protect the firmware from accidental
overwrite and preserve its confidentiality.
The AT91SAM9XE series embeds an Ethernet MAC, one USB Device Port, and a
USB Host Controller. It also integrates several standard peripherals, including six
UARTs, SPI, TWI, Timer Counters, Synchronous Serial Controller, ADC and a
MultiMedia/SD Card Interface.
The AT91SAM9XE system controller includes a reset controller capable of
managing the power-on sequence of the microcontroller and the complete
system. Correct device operation can be monitored by a built-in brownout detector
and a watchdog running off an integrated RC oscillator.
The AT91SAM9XE series is architectured on a 6-layer matrix, allowing a
maximum internal bandwidth of six 32-bit buses. It also features an External Bus
Interface capable of interfacing with a wide range of memory devices.
The pinout and ball-out are fully compatible with the AT91SAM9260 with the
exception that the pin BMS is replaced by the pin ERASE.
