The Atmel® | SMART ARM®-based SAM7S32 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 8KB of SRAM. The peripheral set includes a UART, USART, TWI (I2C), SPI SSC, two PWM timers, three 16-bit timers, RTT, 8x10-bit ADC and 21 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 SAM7S32 operates from 1.65V to 3.6V and is available in 48-pin LQFP and QFN packages.
