Overview

The LC72322R and LC72323R are single-chip

microcontrollers for use in electronic tuning applications.

These ICs include on chip both LCD drivers and a PLL

circuit that can operate at up to 150 MHz. The LC72322R

and LC72323R feature that these ICs are reversed pin-

assignment versions of LC72322 and LC72323

respectively and have the equal functions and

specifications to theirs respectively.
