Overview
The LC72322 is a single-chip microcontroller for use in
electronic tuning applications. It includes on chip both
LCD drivers and a PLL circuit that can operate at up to
150 MHz. It features a large-capacity ROM, a highly
efficient instruction set, and powerful hardware.
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): 4 k words by 16 bits
Data memory (RAM): 256 4-bit digits
All instructions are single-word instructions
Cycle time:
2.67 μs, 13.33 μs, or 40.00 μs (option)
Unlock FF:
0.55 μs detection, 1.1 μs detection
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)
Seven CMOS output ports (mask option
switchable to use as LCD ports)
I/O ports*:
One switchable between input and output
in four-bit units and one switchable
between input and output in one-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)
One external interrupt
Hold mode for RAM backup
Sense FF for hot/cold startup determination
PLL: 4.5 to 5.5 V
CPU: 3.5 to 5.5 V
RAM: 1.3 to 5.5 V
