LC7234
Single-chip PLL and Microcontroller
with LCD Driver
Overview
Package Dimensions
The LC7234 is a single-chip microcontroller that incorpo- unit:mm
rates a 0.5 to 150MHz phase-locked loop (PLL) and a liq-
uid-crystal display (LCD) driver, making it ideal for digi-
tal tuners. It has a large number of input/output ports and a
frequency measurement circuit.
