LC72321
Single-Chip Microcontroller with PLL and LCD Driver
Preliminaly Overview
The LC72321 is a single-chip microcontroller for use in electronic tuning applications. It includes on chip both LCD drivers and a PLL circuit that can operate at up to 150 MHz. It features a large-capacity ROM, a highly efficient instruction set, and powerful hardware. • Voltage detection type reset circuit • One 6-bit A/D converter • Two 8-bit D/A converters (PWM) • One external interrupt (The LC72321 provides an external interrupt, and internal interrupt and a serial I/O interrupt, one of which can be selected under program control.) • Hold mode for RAM backup • Sense FF for hot/cold startup determination • PLL: 4.5 to 5.5 V • CPU: 3.5 to 5.5 V • RAM: 1.3 to 5.
