Description The SA-1110 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 component. The SA-1110 provides portable applications with high-end computing performance without requiring users to sacrifice available battery time. Its power-management functionality provides further power savings. For embedded applications, the SA-1110 offers high-performance computing at consumer electronics pricing with MIPS-per-dollar and MIPS-per-watt advantages. The SA-1110 delivers in price/performance and power/performance, making it a chice for portable and embedded applications. The SA-1110 differs from the Intel® StrongARM SA-1100 Microprocessor (SA-1100) only in the features of its memory and PCMCIA controller.
