MSM64167E Datasheet | OKI Electric

DESCRIPTION 4-Bit Microcontroller with Built-in Dual-Slope Type A/D Converter and LCD Driver The MSM64167E is a low power 4-bit microcontroller that employs Oki's original CPU core n X4/20. 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.
