1. AT91SAM9XE128/256/512 Description
6254C–ATARM–22-Jan-10
•
•
•
The AT91SAM9XE128/256/512 is based on the integration of an ARM926EJ-S processor with
fast ROM and RAM, 128, 256 or 512 Kbytes of 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 AT91SAM9XE128/256/512 embeds an Ethernet MAC, one USB Device Port, and a USB
Host Controller. It also integrates several standard peripherals, like six UARTs, SPI, TWI, Timer
Counters, Synchronous Serial Controller, ADC and a MultiMedia/SD Card Interface.
The AT91SAM9XE128/256/512 system controller includes a reset controller capable of manag-
ing 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 inte-
grated RC oscillator.
The AT91SAM9XE128/256/512 is architectured on a 6-layer matrix, allowing a maximum inter-
nal 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.
