ML610Q411/Q412
8-bit Microcontroller with a Built-in LCD driver
GENERAL DESCRIPTION
ML610Q411/Q412 is a high-performance 8-bit CMOS microcontroller into which rich peripheral circuits, such as synchronous
serial port, UART, I2C bus interface (master), buzzer 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 LAPIS Semiconductor -original
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.
M L610Q411/Q412 has a dual clock, runs at 32.768kHz crystal oscillation clock or a built-in 500kHz RC oscillation clock, used
for a system requires the accurate clock or timer.
