AT91SAM7X256C-AUR

AT91SAM7X256C-AUR is a SAM7X series microcontroller based on the 32bit ARM7TDMI processor. It operates at a maximum speed of 55MHz and features 256KB of flash memory and 64KB of SRAM. The peripheral set includes USB 2.0 full speed device port, Ethernet MAC 10/100 port, CAN 2.0A and 2.0B compliant controller, two USART, UART, two SPI, SSC, TWI (I2C), three 16-bit timers, RTT and 8x10-bit ADC. Typical core supply is 1.8V, I/Os are supplied at 1.8V or 3.3V and are 5V tolerant. An integrated voltage regulator allows single supply at 3.3V. The SAM7X256 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.
