UTLINE
The S1C63358 is a microcomputer which has a high-performance 4-bit CPU S1C63000 as the core
CPU, ROM (8,192 words
×
13 bits), RAM (512 words
×
4 bits), serial interface, watchdog timer, program-
mable timer, time base counter (1 system), SVD circuit, a segment type LCD driver that can drive a
maximum 32 segments
×
4 commons, a 4-channel A/D converter and a special input port that can
implement key position discrimination function using with the A/D converter. The S1C63358 features
low voltage/high speed (4 MHz Max.) operation and low current consumption while the LCD is ON
(current consumption in HALT: 2.5 µA), this makes it suitable for battery driven portable equipment such
as a head phone stereo.
