AT91SAM9XE512B-CU

The SMART SAM9XE microcontroller 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 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 SMART SAM9260 eMPU with the exception that the pin BMS is replaced by the pin ERASE.
