ML610Q421/ML610Q422
8-bit Microcontroller with a Built-in LCD driver
GENERAL DESCRIPTION
This LSI is a high-performance 8-bit CMOS microcontroller into which rich peripheral circuits, such as synchronous serial port,
UART, I
2
C bus interface (master), melody driver, battery level detect circuit, RC oscillation type A/D converter, 12-bit
successive approximation type A/D converter, and LCD driver, are incorporated around 8-bit CPU nX-U8/100.
The CPU nX-U8/100 is capable of efficient instruction execution in 1-intruction 1-clock mode by 3-stage pipe line architecture
parallel procesing. The Flash ROM that is installed as program memory achieves low-voltage low-power consumption operation
(read operation) equivalent to mask ROM and is most suitable for battery-driven applications.
The on-chip debug function that is installed enables program debugging and programming.
