DESCRIPTION
This version: Sep. 1998 MSM5052 Previous version: Mar. 1996
Built-in Temperature Circuit and LCD Driver 4-Bit Microcontroller
The MSM5052 is a low-power microcontroller manufactured in plementary metal-oxide semiconductor technology. Integrated into a single chip are ROM, RAM, crystal oscillator, voltage doubler, timer, LCD driver, input port, output port, and thermistor-based temperature measuring circuit. Using an on-chip ROM reduces power consumption. The MSM5052 is widely used in electronic products requiring low-power operation, for example, thermometer and clinical thermometer.
