1OUTLINE
The S1C63567 is a microcomputer which has a high-performance 4-bit CPU S1C63000 as the core
CPU, ROM (16,384 words
× 13 bits), RAM (5,120 words × 4 bits), serial interface, watchdog timer, pro-
grammable timer, time base counters (2 systems), SVD circuit, a dot-matrix LCD driver that can drive a
maximum 60 segments
× 17 commons, DTMF/DP generator and sound generator built-in. The S1C63567
features high speed operation and low current consumption in an operating voltage range (2.2 V to 5.5
V), this makes it suitable for applications working with batteries. It is also suitable for caller ID and
portable data bank systems because it has a large capacity of RAM built-in.
