■ DESCRIPTION
● Original Architecture Core CPU
● Low Current Consumption
● Wide-range Operating Voltage (2.2V to 5.5V)
● High Speed Operation in Low Voltage (0.56µsec/3.58MHz)
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, programmable 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 applica-
tions 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.
