DESCRIPTION
The E0C6S46 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. The E0C6S46 can be applied to any system requiring large memory such as
schedule reminder, and dot matrix display function.
