BEGV643A User Manual Ver.02- 6 -
1-1 Features
This BEGV643A is designed based on ATmega644p microprocessor, which requires no operating system to run
on. Together with a 320x240 STN LCD and LED backlight built-in, this all-in-one LCD embedded system BEGV643A
help designer enhance a compact design with cost saving, space saving, and design phase saving.
Armed with RS232, RS422/485, I2C and SPI interface port, this BEGV643A communicates many devices and
peripherals. The BEGV643A is therefore suitable to sit as a industrial control panel for factory automation equipment,
electronics instrument, HMI (human-machine interface), office automation equipment, medical equipment, parking
system, ticketing system.. and so on.
There are five LCD colors among choices: STN/gray, STN/yellow-green, STN/blue, FSTN/Positive, and
FSTN/negative. All comes with LED/white backlight.
64KB in-system self-programmable Flash offers sufficient ROM size for designer to develop software, further to
control LCD, touch panel, and interfaces.
Designer may simply design this BEGV643A into your application as you are designing a ATMEL CPU board,
without worrying LCD module and other interfaces, since they are all on one board.
