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.
