Atmel AT91SAM9XE128 Handbook
The AT91SAM9XE128 family integrates an ARM926EJ‑S™ Thumb processor delivering up to 200 MIPS at 180 MHz, on‑chip SRAM, flash memory, and a wide range of peripherals such as Ethernet MAC, USB device/host ports, ADC, and image‑sensor interface. The device is offered in 208‑pin PQFP and 217‑ball LFBGA packages with optional memory configurations (16 KB SRAM / 128 KB flash for the 128‑variant, larger for 256/512).
The handbook details the block diagram, pin multiplexing, signal definitions, electrical and mechanical characteristics, ordering information, and errata. It also describes the reset controller, power‑management controller, advanced interrupt controller, and peripheral DMA controller, providing designers with the data needed for hardware integration and firmware development.
