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 synchronous serial port, UART, melody driver, 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 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 (1.2V or
higher) and low-power consumption (typically 5uA at low-speed operation), enabling volume production by the MTP
version. For industrial use, ML610Q407P/ML610Q408P/ML610Q409P with the extended operating ambient
temperature ranging from -40°C to 85°C are available.
