    SAM9XE Series
    Atmel | SMART ARM-based Embedded MCU
    DATASHEET Description
    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. ...
