DESCRIPTION
The E0C63454 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 E0C63454 can be operated high speed and spend little current. The
E0C63454 has a large RAM and LCD driver, so that the E0C63454 is best suited for systems such as Caller ID
and Data-bank.
