MSM5052
Built-in Temperature Circuit and LCD Driver 4-Bit Microcontroller
GENERAL DESCRIPTION
The MSM5052 is a low-power microcontroller manufactured in complementary 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.
