GDS1111BA

Product Summary

The GDS1111BA is a Intel-StrongARM SA-1110 Microprocessor (SA-1110), which 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 GDS1111BA provides portable applications with high-end computing performance without requiring users to sacrifice available battery time.
