LC72323
Single-Chip Microcontroller with PLL
and LCD Driver
Overview
The LC72323 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 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): 3 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
• 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
• Package: QIP80E
