Ordering number : EN5378
CMOS LSI
LC72322R, 72323R
Single-Chip Microcontroller with PLL
and LCD Driver
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.
Functions
• Stack: Eight levels
• Fast programmable divider
• General-purpose counters: HCTR for frequency
measurement and LCTR for frequency or period
measurement
• LCD driver for displays with up to 56 segments
(1/2 duty, 1/2 bias)
• Program memory (ROM): 4095 (8 KB) 16-bit digits:
LC72322R
3071 (6 KB) 16-bit digits:
LC72323R
• Data memory (RAM): 256 4-bit digits
• All instructions are single-word instructions

high-breakdown voltage open-drain port
Two CMOS output ports (of which one
can be switched to be used as LCD driver
outputs)
Seven CMOS output ports (mask option
switchable to use as LCD ports)

in four-bit units and one switchable
between input and output in bit units
Note: * Each port consists of four bits.
• Program runaway can be detected and a special address
set (Programmable watchdog timer).
