E0C624A Overview
The E0C624A is an advanced single-chip CMOS 4-bit microputer 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.
