SAM9XE Series Datasheet
Atmel | SMART ARM-based Embedded MCU
The AtmelВ® | SMART SAM9XE microcontroller series is based on the integration
of an ARM926EJ-Sв„ў 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 SAM9XE 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 SAM9XE 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 SAM9XE series architecture includes 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 Atmel | SMART SAM9260
eMPU with the exception that the pin BMS is replaced by the pin ERASE. ...
