s DESCRIPTION
The E0C6266 is an advanced single-chip CMOS 4-bit microcomputer consisting of the E0C6200 CMOS 4-bit core CPU. It also contains the ROM, RAM, 2-channel timer, event counter, start-stop serial ports, clock sync serial ports and 40 I/O ports. The E0C6266 provides an excellent solution for low-power consumption systems with clock functions.
