E0C624A
4-bit Single Chip Microcomputer
q Core CPU Architecture
q Dot Matrix LCD Driver
q Programmable SVD Circuit/Sound Generator
s DESCRIPTION
The E0C624A is an advanced single-chip CMOS 4-bit microcomputer consisting of the E0C6200 4-bit core
CPU. The chip contains the ROM, RAM, dot matrix LCD driver, programmable SVD circuit, time base counter
and clock synchronous serial port.
Interfacing with the external memory, the E0C624A can be applied to any system requiring large memory such
as schedule reminder, and dot matrix display function.
