Product Features
The Intel

StrongARM SA-1110 Microprocessor (SA-1110) is a device
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 has a large instruction and data
cache, memory-management unit (MMU), and read/write buffers. The
SA-1110 memory bus interfaces to many device types including
synchronous DRAM (SDRAM), synchronous mask ROM (SMROM), and
SRAM-like variable latency I/O devices with a shared data ready signal. In
addition, the SA-1110 provides system support logic, multiple serial
communication channels, a color/gray scale LCD controller, PCMCIA
support for up to two sockets, and general-purpose I/O ports.
