S1C63654
4-bit Single Chip Microcomputer
● Original Architecture Core CPU
● Low Current Consumption
● High Speed Operation in Low Voltage
„ DESCRIPTION
The S1C63654 is a microcomputer which has a high-performance 4-bit CPU S1C63000 as the core CPU, ROM
(4,096 words × 13 bits), RAM (512 words × 4 bits), serial interface, watchdog timer, programmable timer, time
base counters (2 systems), an LCD driver that can drive a maximum 32 segments × 6 commons, sound
generator and R/f converter built-in. The S1C63654 features low current consumption, this makes it suitable for
battery driven portable equipment with R/f converter.
