Digital PCB is composed Microprocessor (IC600), D RAM (IC601), Flash Memory (IC602), Gate Array (IC700),
and V RAM (IC701).
Microprocessor controls the CCD, D RAM, Flash Memory and key operation. Gate array compresses data
for the color and the luminance from the CCD to increase the number of memory, and up to 96 images can
be stored in flash memory. The color and the luminance data are mixed in the gate array to make the video
signal.
As to spare parts for digital PCB, Casio supplies PCB ass'y and the individual parts.
