LC72336, 72338
Single-Chip Microcontrollers
with Built-In LCD Driver and PLL Circuits
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.
