Atmel AT91SAM7S64 Datasheet

The AT91SAM7S64 is built around an ARM7TDMIe core with Thumb support, offering a high‑performance 32‑bit RISC architecture. It includes 64 KB of on‑chip Flash memory and 16 KB of high‑speed SRAM, and can operate at up to 30 MHz.

The device provides a rich set of peripherals such as two UARTs, USART with IrDA and RS‑485 support, SPI, PWM, a programmable timer, and a flexible I/O controller. Power management features include multiple clock sources (RC oscillator, on‑chip 3‑20 MHz oscillator, PLL) and low‑power modes, while the advanced interrupt controller and debug unit aid development and debugging. This manual is written in Chinese.
