Overview
The LC680100A is a 32 bit microcontroller developed exclusively by Sanyo, based on a 32 bit RISC CPU and incorporating on a single chip a high speed multiplier, 2kB of cache RAM, 2kB data RAM, DRAM control unit, external memory control unit and peripheral
It is an ideal control device for digital cameras, color printers and hand held data terminals.
