s DESCRIPTION
The E0C6282 is an advanced single-chip CMOS 4-bit microcomputer consisting of the E0C6200A CMOS 4-bit
core CPU. It also contains the ROM, RAM, LCD driver circuit, time base counter, stopwatch counter and melody
generation circuit.
The E0C6282 provides an excellent solution for low-power consumption systems with clock functions.
