AT91SAM7S64C-AU

The AT91SAM7S64C-AU is a SMART ARM®-based Microcontroller, 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 1.65 to 3.6V. The SAM7S series has a static current of less than 60μA on VDDCORE at 25°C, including the RC oscillator, the voltage regulator and the power-on reset. When the brown-out detector is activated, 20μA static current is added. The dynamic power consumption on VDDCORE is less than 50mA at full speed when running out of the flash.
