Measurement MCU

MCU for digital Multimeter

The S1C17M02/M03 are 16-bit MCUs specializing in DMM (Digital Multimeter) functions that support C programming. These MCUs have implemented the functions (ΣΔ A/D converter, pin switching circuit, and reference voltage generator) required for developing  a DMM that can perform various measurements. In addition, they have an embedded square root circuit which reduces the CPU load for software processing.
