S1C63657
CMOS 4-bit Single Chip Microcontroller
● High Performance 4-bit Core CPU S1C63000
● LCD Driver (56 SEG × 8 COM)
● R/f Converter to Measure Temperature and Humidity
● Low Current Consumption
● Low Voltage Operation
■ DESCRIPTIONS
The S1C63657 is a microcomputer which has a high-performance 4-bit CPU S1C63000 as the core CPU, ROM (8,192
words × 13 bits), RAM (1,024 words × 4 bits), multiply-divide circuit, watchdog timer, programmable timer, time base
counter, an LCD driver that can drive a maximum 56 segments × 8 commons, sound generator and R/f converter built-in.
The S1C63657 features low current consumption, this makes it suitable for battery driven portable equipment with R/f
converter.
