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.
