Microcontrol Electronics AT91SAM9261 Datasheet

The AT91SAM9261 is a system‑on‑chip built around an ARM926EJ‑S ARM Thumb core, extending the DSP instruction set and including a Jazelle Java accelerator. It offers up to 210 MIPS at 190 MHz, 32 KB on‑chip ROM, 160 KB SRAM, and a rich set of peripherals such as LCD controller, USB 2.0, Ethernet, and multiple serial interfaces.

The datasheet details the pin‑out, signal functions, voltage domains, and mechanical package (217‑ball LFBGA, 15 × 15 mm, 0.8 mm ball pitch). It also describes the memory controller, SDRAM interface, USB host/device ports, multimedia card interface, and various timers and counters, providing developers with the information needed for hardware design and software integration. This manual is written in Chinese.
