Overview
The LC72336 and LC72338 are single-chip
microcontrollers for use in electronic tuners. These
products include on chip a PLL circuit that can operate at
up to 150 MHz and 1/3 duty LCD drivers. They feature a
highly efficient instruction set and powerful hardware.

Internal interrupts: 3 interrupt
Two built-in timer interrupts and 1 serial I/O interrupt
Nested interrupt levels: 4 levels
D/A converter: 4 channels (8-bit PWM output)
A/D converter: 4 channels
(6-bit successive approximation)
General-purpose ports:
-- Input ports: 8
-- Output ports: 12 (16 maximum)
-- I/O ports: 8 (20 maximum, can be switched between
input and output in bit units.)
PLL block: Supports 4 types of dead zone control, and
includes a built-in unlock detection circuit.
Supports 12 different reference frequencies.
Universal counter: 20 bits (Can be used for either
frequency or period measurement.)
Timers: Eight types of time measurement
Beep function: Six beep tones
Reset: Built-in voltage detection type reset circuit
Halt mode: Stops the controller operating clock.
Operating supply voltage: 4.5 to 5.5 V (3.5 to 5.5 V if
only the controller block operates.)
