A member of the Atmel SAM7X series of microcontrollers based on the 32-bit ARM7TDMI processor. It operates at a maximum speed of 55 MHz and features 128KB of flash and 32KB of SRAM. The peripheral set includes USB 2.0 full speed device port, Ethernet MAC 10/100Base T port, CAN 2.0A and 2.0B compliant controller, two USARTs, UART, two SPI, SSC, TWI, 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 SAM7X128 is supplied in 100-lead LQFP and TFBGA packages.
