UTLINE
The S1C63558 is a microcomputer which has a high-performance 4-bit CPU S1C63000 as the core
CPU, ROM (8,192 words
×
13 bits), RAM (5,120 words
×
4 bits), serial interface, watchdog timer, program-
mable timer, time base counters (2 systems), SVD circuit, a dot-matrix LCD driver that can drive a
maximum 40 segments
×
17 commons, DTMF/DP generator, FSK demodulator and sound generator
built-in. The S1C63558 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.
