Overview

The LC75710NE series products are dot matrix VFD controller/driver LSIs that display characters, numbers, and symbols. These LSIs generate dot matrix VFD drive signals based on serial data sent from a microprocessor, and allow display systems to be implemented easily using the built-in character generator ROM and RAM.

The LC75710NE series products are fabricated in a CMOS process and can contribute to achieving low-power operation in user applications.
