The Microchips ARM-based SAM7X256 is a member of the Microchip SAM7X series of microcontrollers based on the 32-bit 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 is supplied in 100-lead LQFP and TFBGA packages.Incorporates the ARM7TDMI ARM Thumb® Processor High-performance 32-bit RISC Architecture High-density 16-bit Instruction Set EmbeddedICE™T0/T1 Smart Card, Hardware Handshaking, RS485 Support Full Modem Line Support on USART1 Two Master/Slave Serial Peripheral Interfaces 8- to 16-bit Programmable Data Length.
