Atmel AT91SAM9261 Datasheet
The AT91SAM9261 is a system‑on‑chip built around the ARM926EJ‑S™ ARM® Thumb® processor, delivering 210 MIPS at 190 MHz. It integrates 32 KB of internal ROM, 160 KB of SRAM, 16 KB each of data and instruction cache, and a rich set of peripherals including LCD controller, USB host/device, DMA channels, and multiple serial interfaces.
The device is offered in a 217‑ball LEBGA RoHS‑compliant package and supports a wide range of power supplies (VDDCORE 1.08‑1.32 V, VDDIOP 2.7‑3.6 V, VDDIOM 1.65‑1.95 V/3.0‑3.6 V). The handbook includes a block diagram, detailed signal descriptions, pin‑out tables, memory mapping, and a revision history for engineering reference.
