Yellow 40x2 Character Standard LCD

Part Number: CFAH4002A-YYH-JT

Standard 40x2 Character LCD – Dark On Yellow-Green

If you need to display a lot of information on your device, this extra wide LCD will do the job with an active area of 5.8-inches (147.50 millimeters). Like all transflective displays, the 5x8 character matrix on this 40 x 2 LCD screen can be read in direct sunlight, is good for typical office lighting, and is easy to read in dark locations. One of our customers bought a display in the CFAH4002A series to use in an environmental control system for irrigation management.

Key Features

• 2 lines with 40 characters each, industry standard 40x2 form factor
• The built-in alphanumeric set supports Japanese and English text
• Built-in Sitronix ST7066U or compatible controller.
• Sunlight readable
• Adjust backlight contrast by using PWM (Pulse Width Modulation)

As with other standard character displays, the parallel interface communicates with your host using 4-bit or 8-bit mode. The built-in Sitronix ST7066U controller is compatible with the industry standard Hitachi HD44780 controller. Software written for the HD44780 should work without any changes. For controller details, see the Sitronix ST7066U datasheet on our website.

Our goal is to keep every product available as long as possible. We've sold the CFAH4002A series since 2008 and it is still going strong. The yellow-green LED backlight on this STN (Super-Twisted Neumatic) display module is rated to operate continuously for up to 17 years! A simple current limiting resistor in line with the voltage source works well in most applications. The yellow-green LEDs do not demand a current source, although one may be used. For details, see the backlight section starting on page 22 of the datasheet.
