ML610Q101/ML610Q102

8-bit Microcontroller

1/21

GENERAL DESCRIPTION

This LSI is a high-performance 8-bit CMOS microcontroller into which rich peripheral circuits, such as timers, PWM, UART,

voltage level supervisor (VLS) function, and 10-bit successive approximation type A/D converter, 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 pipe line architecture parallel

processing.

The on-chip debug function that is installed enables program debugging and programming.
