CHAPTER
1INTRODUCTION
Each member of the S1C6N3B0 Series of single chip microcomputer features a 4-bit S1C6200B core CPU,
1,536 words of ROM (12 bits per word), 96 words of RAM (4 bits per word), an LCD driver, 4-bit input
port (K00–K03), 4-bit output port (R00–R03), 4-bit I/O port (P00–P03), two timers (clock timer and
stopwatch timer) and serial interface. Because of their low voltage operation and low power consump-
tion, the S1C6N3B0 Series are ideal for a wide range of applications.
1.1 Configuration
The S1C6N3B0 Series is configured as follows, depending on the supply voltage and the oscillation circuit.
