Low Voltage
Operation
Products
● Built-in Dot-matrix LCD Driver
● Low Voltage Operation (2.2V Min.)
● High Speed Instruction Cycle (2-6CPI)
■ DESCRIPTION
The E0C63557 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 E0C63557 can be operated with high speed and spend little current. The
E0C63557 has large RAM and LCD driver, so that the E0C63557 is best suited for systems such as Caller ID
and Data-bank.
