DESCRIPTION
The E0C88861 is a CMOS 8-bit microcomputer composed of a CMOS 8-bit core CPU, ROM, RAM, I/O, serial
interface, dot-matrix LCD driver, timer and event counter. The E0C88861 fully operable over a wide range of
voltages, and can perform high speed operations even at low voltage. The E0C88861 features low current
consumption, this makes it suitable for battery driven portable equipment.
