DESCRIPTION
The E0C88862 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 E0C88862 fully operable over a wide range of
voltages, and can perform high speed operations even at low voltage and low current consumption, it is suitable
for portable systems that need to be driven with a battery.
