The ARM920T and ARM922T hard macrocells are suitable for a wide range of platform OS based applications. Based around the high performance ARM9TDMI 32-bit RISC CPU, the ARM920T and ARM922T processors feature instruction and data caches, memory management unit (MMU) enabling support for all major operating systems (OS), AMBA® bus-compliant interfaces, and support for ARM's real-time trace technology with the optional ETM9TM Embedded Trace Macrocell. The ARM922T is identical to the ARM920T but has 8K/8K caches while the ARM920T has 16K/16K caches.

The ARM922T processor is available via the ARM Foundry Program.
