S1C63653
CMOS 4-bit Single Chip Microcontroller
● High Performance 4-bit Core CPU S1C63000
● LCD Driver (32 SEG × 6 COM)
● R/f Converter to Measure Temperature and Humidity
● Low Current Consumption
● Low Voltage Operation
■ DESCRIPTIONS
The S1C63653 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), watchdog timer, programmable timer, time base counter, an LCD driver that
can drive a maximum 32 segments × 6 commons, sound generator and R/f converter built-in. The S1C63653 features low
current consumption, this makes it suitable for battery driven portable equipment with R/f converter.
