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

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

Low-threshold type dedicated input port
These pins can be used, for example, for key data acquisition.
Built-in pull-down resistors can be specified as an option. This
option is in 4-pin units, and cannot be specified for individual
pins.
Input through these pins is disabled in BACK UP mode.
Dedicated output ports
Since the output transistor impedances are unbalanced
CMOS, these pins can be effectively used for functions such
as key scan timing. These pins go to the output high-
impedance state in BACK UP mode.
These pins go to the low level during a reset, i.e., when the
RES pin is low.
Dedicated output ports
These are normal CMOS outputs. These pins go to the output
high-impedance state in BACK UP mode.
These pins go to the low level during a reset, i.e., when the
RES pin is low.
I/O port
These pins are switched between input and output as follows:
Once an input instruction (IN, TPT, or TPF) is executed, these
pins latch in the input mode. Once an output instruction (OUT,
SPB, or RPB) is executed, they latch in the output mode.
These pins go to the input mode during a reset, i.e., when the
RES pin is low.
In BACK UP mode these pins go to the input mode with input
disabled.
I/O port
These pins are switched between input and output by the
FPC instruction.
The I/O states of this port can be specified for individual pins.
These pins go to the input mode during a reset, i.e., when the
RES pin is low.
In BACK UP mode these pins go to the input mode with input
disabled.
Dedicated input port
Input through these pins is disabled in BACK UP mode.

Dedicated output port
Since these pins are high-breakdown voltage n-channel
transistor open-drain outputs, they can be effectively used for
functions such as band power supply switching.
Note that PH2 and PH3 also function as the DAC1 and DAC2
outputs.
These ports go to the high impedance state during a reset,
i.e., when the RES pin is low, and in BACK UP mode.
Dedicated output port
While these pins have a CMOS output circuit structure, they
can be switched to function as LCD drivers. Their function is
switched by the SS and RS instructions. These pins cannot
be switched individually.
The LCD driver function is selected and a segment-off signal
is output when power is first applied or when RES is low.
These pins are held at the low level in BACK UP mode.
Note that when the general-purpose port use option is
specified, these pins output the contents of IPORT when LPC
is 1, and the contents of the general-purpose output port
LATCH when LPC is 0.
LCD driver segment outputs
A frame frequency of 100 Hz and a 1/2 duty, 1/2 bias drive
type are used.
A segment-off signal is output when power is first applied or
when RES is low.
These pins are held at the low level in BACK UP mode.
The use of these pins as general-purpose output ports can be
specified as an option.
LCD driver common outputs
A 1/2 duty, 1/2 bias drive type is used.
The output when power is first applied or when RES is low is
identical to the normal operating mode output.
These pins are held at the low level in BACK UP mode.
FM VCO (local oscillator) input
The input must be capacitor coupled.
The input frequency range is from 10 to 130 MHz.
AM VCO (local oscillator) input
The band supported by this pin can be selected using the PLL
instruction.

Universal counter input
The input should be capacitor coupled.
The input frequency range is from 0.4 to 12 MHz.
This input can be effectively used for FM IF or AM IF counting.
Universal counter input
The input should be capacitor coupled for input frequencies in
the range 100 to 150 kHz.
Capacitor coupling is not required for input frequencies from
1 to 20 Hz.
This input can be effectively used for AM IF counting.
This pin can also be used as a normal input port.
A/D converter input
A 1.28 ms period is required for a 6-bit sequential comparison
conversion. The full scale input is ((63/96) V
DD
) for a data
value of 3FH.
External interrupt request input
An interrupt is generated when the INTEN flag is set (by an
SS instruction) and a falling edge is input.
This pin can also be used as a normal input port.
Reference frequency and programmable divider phase
comparison error outputs
Charge pump circuits are built in.
EO1 and EO2 are the same.
Input pin used to determine if a power outage has occurred in
BACK UP mode
This pin can also be used as a normal input port.
Input pin used to force the LC72322 to HOLD mode
The LC72322 goes to HOLD mode when the HOLDEN flag is
set (by an SS instruction) and the HOLD input goes low.
A high-breakdown voltage circuit is used so that this input can
be used in conjunction with the normal power switch.
System reset input
This signal should be held low for 75 ms after power is first
applied to effect a power-up reset.
The reset starts when a low level has been input for at least
six reference clock cycles.
Crystal oscillator connections
