S1C6S2N7 TECHNICAL HARDWARE EPSON I-1

CHAPTER 1: INTRODUCTION

INTRODUCTION

Each member of the S1C6S2N7 Series of single chip micro-

computers features a 4-bit S1C6200A core CPU, 1,536

words of ROM (12 bits per word), 80 words of RAM (4 bits

per word), an LCD driver, 4 bits for input ports (K00–K03), 4

bits for output ports (R00–R03), 4 bits for I/O ports (P00–

P03), two timers (clock timer and stopwatch timer) and a

motor driver.

The S1C6S2N7 Series features low-voltage operation and

low current consumption, this makes it suitable for battery

driven systems such as combination quartz watches.
