MSM64167E
4-Bit Microcontroller with Built-in Dual-Slope Type A/D Converter and LCD Driver
GENERAL DESCRIPTION
The MSM64167E is a low power 4-bit microcontroller that employs Oki's original CPU core nX4/20.
The MSM64167E contains a dual-slope type A/D converter with a 4-channel input, LCD driver
for up to 108 segments, and buzzer output port.
The MSM64167E is best suited for applications such as low power, high precision thermometers,
barometers, and hygrometers.
