The document describes a single-chip solution that incorporates the ARM920T™ ARM® Thumb® processor, offering high performance and low power consumption. It also includes internal memories, an external bus interface, and various system peripherals that provide support for enhanced performance.
The AT91RM9200 is an ARM920T‑based microcontroller that integrates a rich set of peripherals, including Ethernet, USB, multimedia card, and multiple serial interfaces. It offers low‑power operation with 24.4 mA normal mode current and 520 pA standby current, and provides up to 122 programmable I/O lines.
The device is offered in two package types—a 208‑pin PQFP and a 256‑ball BGA—each supporting different peripheral extensions such as a second USB host transceiver and additional PIO controller features. Detailed pin descriptions, signal definitions, and revision history are included for designers.
