CMOS IC
LC7234-8460
Single-chip PLL and Microcontroller
with LCD Driver
Preliminary
Overview
The LC7234-8460 is a single-chip microcontroller that in-
corporates a phase-locked loop (PLL) and a liquid crystal
display driver.
The LC7234-8460 operates over the American, European,
Chinese, Middle Eastern, Canadian and Australian LW,
MW, SW and FM bands, and incorporates preset-channel
memory, automatic or manual tuning, high-speed station
search, and clock and timer functions.
The LC7234-8460 operates from a 5 V supply and is avail-
able in 64-pin QIPs.
