Overview

The LC7233N is a single-chip microcontroller that incorporates a 0.5 to 150 MHz phase-locked loop (PLL) and a liquid-crystal display (LCD) driver, making it ideal for digital tuners. It has a large number of input/output ports and a frequency measurement circuit.

The LC7233N features on-chip RAM and ROM, a programmable high-speed divider, a 6-bit analog-to-digital converter and a low-voltage detection reset circuit.

The LC7233N operates from a 5 V supply and is available in 64-pin QIPs.
