Single-Chip Microcontroller with PLL
and LCD Driver
LC72322R, 72323R
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:

Timer FF:
1 ms, 5ms, 25ms, 125ms
Input ports*: One dedicated key input port and one
high-breakdown voltage port
Output ports*:Two dedicated key output ports, one
high-breakdown voltage open-drain port
Two CMOS output ports (of which one
can be switched to be used as LCD driver
outputs)

switchable to use as LCD ports)
One switchable between input and output
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).
Voltage detection type reset circuit
One 6-bit A/D converter
Two 8-bit D/A converters (PWM): LC72322R only
One external interrupt
Hold mode for RAM backup
Sense FF for hot/cold startup determination
