The LC7232N is a single‑chip microcontroller that integrates a 0.5‑to‑156 MHz phase‑locked loop, LCD driver, analog‑to‑digital and digital‑to‑analog converters, on‑chip RAM/ROM, and multiple I/O ports, making it suitable for digital tuner applications. It operates from a 5 V supply and is available in an 80‑pin QIP package.
The datasheet includes electrical characteristics, pin assignments, package dimensions, and a development system example using an LC72BV32 evaluation chip on a TB‑72EV32 target board.
