This is a chip that integrates ARM7TDMI® ARM® Thumb® processor, 64K bytes of on-chip high-speed flash memory, 16K bytes of on-chip high-speed SRAM, 11 peripheral data controllers (PDC) channels, and a USB 2.0 full-speed (12 Mbps) device port
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.
