ML610Q461/ML610Q462/ML610Q463

8-bit Microcontroller with a Built-in LCD driver

GENERAL DESCRIPTION

This LSI is a high-performance 8-bit CMOS microcontroller into which peripheral circuits, such as synchronous serial port,

UART, RC oscillation type A/D converter, and LCD driver, are incorporated around LAPIS Semiconductor-original 8-bit CPU

nX-U8/100. ML610Q461 operates in both high/low-speed mode and power-saving mode, it is most suitable for battery operated

products.

ML610Q461P/ML610Q462P/ML610Q463P support industrial temperature -40

°C to +85°C, are added to the product lineup.
