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.
