INTRODUCTION

Each member of the E0C6001 Series of single chip micro-

computers feature a 4-bit E0C6200B core CPU, 1,024 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), 2

bits for output ports (R00, R01), one 4-bit I/O port (P00–

P03) and one timer (clock timer).

Because of their low voltage operation and low power con-

sumption, the E0C6001 Series are ideal for a wide range of

applications.

Configuration

The E0C6001 Series are configured as follows, depending on

the supply voltage.
