ML610471/472/473/Q471/Q472/Q473

8-bit Microcontroller with a Built-in LCD driver

GENERAL DESCRIPTION

This LSI is a high performance CMOS 8-bit microcontroller equipped with an 8-bit CPU nX-U8/100 and integrated with

peripheral functions such as the UART, RC oscillation type A/D converter, and LCD driver.

The CPU nX-U8/100 is capable of efficient instruction execution in 1-intruction 1-clock mode by 3-stage pipe line architecture

parallel processing. Additionally, it adopts the low-/high-speed dual clock system, standby mode, and process that prohibits

leak current at high temperatures, and is most suitable for battery-driven applications.

MTP version (ML610Q471/ML610Q472/ML610Q473) can rewrite programs on-board, which can contribute to reduction in

product development TAT. The flash memory incorporated into this MTP version implements the mask ROM-equivalent

low-voltage operation (1.25V or higher) and low-power consumption (typically 5uA at low-speed operation), enabling volume

production by the MTP version.

For industrial use, ML610471P/ML610472P/ML610473P/ML610Q471P/ML610Q472P/ML610Q473P with the extended

operating ambient temperature ranging from -40°C to 85°C are available.
