A member of the Atmel SAM7XC series of crypto microcontrollers based on the 32-bit ARM7TDMI processor. It operates at a maximum speed of 55MHz and features 512KB of flash and 32KB of SRAM. The 512KB of flash are split in two banks of 256KB. The peripheral set includes USB 2.0 full speed device port , Ethernet MAC 10/100 port, CAN 2.0A and 2.0B compliant dontroller, two USART, UART, two SPI, SSC, TWI (I2C), three 16-bit timers, RTT and 8x10-bit ADC. The SAM7XC512 embeds two cryptography blocks, one AES128/192/256 encryption accelerator and one Triple DES. 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 SAM7XC512 is supplied in 100-lead LQFP and TFBGA packages.
