1. Overview
1.1 Features
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.
