The S1C6P366 is a microcomputer which has a high-performance 4-bit CPU S1C63000 as the core
CPU, rewritable PROM, RAM, serial interface, watchdog timer, programmable timer, time base counter (1
system), SVD circuit, a segment type LCD driver (32 segments × 4 commons), A/D converter and a
special input port that can implement key position discrimination function using with the A/D converter.
The S1C6P366 has a built-in large capacity PROM (16K × 13 bits) and RAM (2K × 4 bits) that are compat-
ible with the S1C63358 and S1C63158, it can therefore be used as an MTP (Multi-Time Programming) for
program development.
