DESCRIPTION
The E0C63558 is a CMOS 4-bit microcomputer composed of a CMOS 4-bit core CPU, ROM, RAM, dot-matrix
type LCD driver and counters. And the E0C63558 can be operated with high speed and spend little current. The
E0C63558 has large RAM and LCD driver, so that the E0C63558 is best suited for systems such as Caller ID
and Data-bank.
