LC5852N
Four-Bit Single-Chip Microcontroller with
On-Chip LCD Drivers for Small-Scale Control in
Medium-Speed Applications
Overview
The LC5852N is a high-performance four-bit single-chip
built-in LCD driver microprocessor that provides a variety
of attractive features including low-voltage operation and
low power dissipation. The LC5852N was developed as an
upwardly compatible version of the LC5851N and
provides a ROM capacity increased from 1024 to 2048 15-
bit words and a RAM capacity increased from 64
