CHAPTER 1: OUTLINE

CHAPTER 1 OUTLINE

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, programmable 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.
