ML64168

GENERAL DESCRIPTION

This version: Sep. 27,1999

Previous version: Jun. 22,1999

4-Bit Microcontroller with Built-in RC Oscillation Type A/D Converter and LCD Driver

The ML64168 is a low power 4-bit microcontroller incorporating the Oki's original CPU core nX-4/30.

The ML64168 provides a minimum instruction execution time of 4.3µs (@700kHz).

The ML64168 contains 8160-byte program memory, 512-nibble data memory, three 4-bit input-output

ports, 4-bit input port, 4-bit output port, 2-channel RC oscillation type A/D converter, LCD driver for up

to 120 segments, and buzzer output port.

The ML64P168 is the one-time-programmable ROM version of ML64168, having one-time

PROM(OTP) as internal program memory. The ML64P168 is used to evaluate the software

development.

APPLICATION

The ML64168 is best suited for low power, high precision thermometers and hygrometers.
