OVERVIEW
The S1C17M02/M03 is a compact 16-bit MCU specializing in a DMM (Digital Multi-Meter) function that
supports C programming. This MCU has implemented the functions (ΣΔ A/D converter, pin switching circuit, and
reference voltage generator) required for composing a DMM that is able to measure voltage, current, resistance,
capacitance, diode, frequency, and continuity check. Also it is possible to setup optimal measurement conditions
with programmable oversampling settings and to reduce a load on software processing with an embedded square
root circuit. The S1C17M02/M03 includes a low-power LCD driver, various serial interfaces, a crystal oscillator
and various timers as well, thus it is suitable for battery drive measurement equipment not only a DMM. It not only
has a Flash memory but also an EEPROM that can be reprogrammed from application software.
