AT91SAM9XE-EK

The AT91SAM9XE-EK evaluation kit enables the evaluation and code development for applications running on an AT91SAM9XE device. 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. This controller includes a reset controller capable of managing the power-on sequence of the microcontroller and the complete system.
