The Intel StrongARM SA-1110 processor is optimized for meeting portable and embedded application requirements. The SA-1110 incorporates a 32-bit StrongARM RISC processor capable of running at up to 206 MHz. The SA-1110 contains an MMU, an LCD controller, and serial I/O, all combined in a single component.

Embedded Linux support for the SA-1110 and its companion chip is available from several third-party providers.
