AT91SAM9XE512

The AT91SAM9XE128 AT91SAM9XE256 AT91SAM9XE512 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 and a secu- rity bit protect the firmware from accidental overwrite and preserves its confidentiality. The AT91SAM9XE128 AT91SAM9XE256 AT91SAM9XE512 embeds an Ethernet MAC one USB Device Port, and a USB Host Controller. It also integrates several standard peripherals, like USART, SPI, TWI, Timer Counters Synchronous Serial Controller, ADC and a Multimedia Card Interface The AT91SAM9XE128 AT91SAM9XE256 AT91SAM9XE512 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 AT91SAM9XE256 AT91SAM9XE512 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. By ATMEL Corporation
