SA-1100

The Intel^® StrongARM^® SA-1100 Microprocessor (SA-1100) is a device targeted to provide portable applications with high-end computing performance without requiring users to sacrifice available battery time. The SA-1100 incorporates a 32-bit StrongARM^® RISC processor running at 133/190 MHz with instruction and data cache, memory-management unit (MMU), and read/write buffers. In addition, the SA-1100 provides system support logic, multiple serial communication channels, a color/gray scale LCD controller, PCMCIA support for up to two sockets, and generalpurpose I/O ports.

† Power dissipation, particularly in idle mode, is strongly dependent on the details of the system design

The SA-1100 is a general-purpose, 32-bit RISC microprocessor with a 16 Kbyte instruction cache (Icache), an 8 Kbyte write-back data cache (Dcache), a minicache, a write buffer, a read buffer, an MMU, an LCD controller, and serial I/O combined in a single chip. The SA-1100 provides powermanagement functionality and offers further power savings and integration by including oscillators and PLLs on-chip. The SA-1100 delivers both extensive system integration and high-end desktop performance without sacrificing power or price, making the SA-1100 a choice for many portable systems.
