LC-8210 Display Unit
This section explains the block diagram and the functions of the LC-8210 Display Unit.
Main CPU Board (PCB-7500) Circuit Description
The Main CPU Board controls, displays, and records the monitor. The input signal operations of the
touch panel, etc are processed by the CPU and then the display of the monitor or each
measurement condition will change.
CPU
The CPU controls memories such as DRAM, each peripheral IC, and sound source, displays the
waveform, numeric data, and menu, and processes manipulated input signals from the Touch
Panel. DMAC (Direct Memory Access), Timer and SCI (Serial Communication Interface) are
incorporated.
Flash Memory
Flash Memory holds the program. And using Flash Memory, the program can be easily upgraded.
