Frequently Asked Questions
How many characters and rows does the 204A-CC-BC-3LP display support for embedded HMI designs?
The 204A-CC-BC-3LP provides 4 rows by 20 characters per row, yielding 80 total character positions for displaying multi-line status text, sensor readings, and menu structures in industrial and laboratory embedded systems with standard 5V or 3.3V microcontroller interfaces.
What interface standard does the 204A-CC-BC-3LP use and which microcontrollers are compatible?
The 204A-CC-BC-3LP uses the HD44780-compatible 16-pin parallel interface operating at 4-bit or 8-bit data width, making it directly compatible with Arduino, STM32, PIC, and AVR microcontrollers using open-source display libraries without custom driver development.
Is the 204A-CC-BC-3LP suitable for outdoor or high-ambient-light environments?
Yes, the 204A-CC-BC-3LP uses a transflective LCD panel that reflects ambient light to improve contrast in bright environments while the white-on-blue LED backlight maintains readability in low-light conditions, providing a viewing angle of approximately 65 degrees for field-deployed equipment at operating temperatures from 0°C to +50°C.
What supply voltage does the 204A-CC-BC-3LP require and how is backlight brightness controlled?
The 204A-CC-BC-3LP logic operates at 5V DC with backlight LED supply typically at 5V and 20mA to 60mA current draw depending on desired brightness, controllable via an external series resistor on pin 15 or PWM signal for dimming control in power-sensitive embedded applications.
