DESCRIPTION
The S1C63158 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, programmable timer, time
base counter (1 system), SVD circuit, 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 S1C63158 features low voltage/high
speed (4 MHz Max.) operation and low current consumption (2
μA
Typ. in HALT mode), this makes it suitable
for battery driven portable equipment such as a head phone stereo.
