DESCRIPTION
The E0C63256 is a microcomputer composed of a CMOS 4-bit core CPU (E0C63000), ROM, RAM, LCD driver
and timers. Since the E0C63000 core CPU executes the principle instructions in 1 or 2 cycles, it is suitable for
various high-speed controller. Furthermore, the E0C63256 has built-in four-channel 8-bit A/D converter and is
most suitable for applications such as control units for household electric appliances which need A/D conver-
sion and liquid crystal display.
