DIGITAL (Serial I/O)
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.
