CMOS IC
LC72321N, 72322N, 72323N
Single-Chip Microcontrollers with Built-in LCD Driver
and PLL Circuits
Overview
The LC72321N, LC72322N, and LC72323N are single-
chip microcontrollers designed for electronic tuning in
radio receivers and include an on-chip LCD driver circuit
and a PLL circuit that operates at 150 MHz. These
microcontrollers feature a large program ROM capacity,
an efficient instruction set, and powerful hardware. Note
that the LC72321N, LC72322N, and LC72323N provide
functions equivalent to the LC72321, LC72322, and
LC72323, and are software compatible with those
products.

• Input ports*: One dedicated key input port, and one
high-voltage port
• Output ports*:
Two dedicated key output ports, one high-voltage open-
drain port
Two CMOS output ports (one of which can be switched
over to function as an LCD driver output)
Seven CMOS output ports (Switching these ports over
to function as LCD driver outputs is supported as an
option.)
• I/O ports*:
One port switchable between input and output in 4-bit units
One port switchable between input and output in 1-bit units
*: Each port consists of 4 bits.
