8-bit Microcontroller with a Built-in LCD driver
FEDL610473-07
Issue Date Jan. 7, 2013
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.
