Microchip's ARM®-based SAM7S64 is a member of the SAM7S series of flash microcontrollers based on the 32-bit ARM7TDMI RISC processor.
It operates at a maximum speed of 55MHz and features 32KB of flash memory and 16KB of SRAM.
The peripheral set includes a Full Speed USB device and PHY at 12Mbps, UART, two USARTs, TWI I2C), SPI, SSC, two PWM timers, three 16-bit timers, RTT, 8x10-bit ADC and 32 IO lines.
It achieves single-cycle instruction access from embedded flash at 27 MIPS.
The multi-layer bus matrix, multiple SRAM banks, PDC, and DMA support parallel tasks and maximize data throughput.
The SAM7S64 operates from 1.65V to 3.6V and is available in 64-pin LQFP and QFN packages.
