XDMDK14A3 is one of the most popular LED character and numeric display modules in the market today. The module features a 14-character display, each character being 8 dots in height, 14 dots in width and 5mm thick. Featuring a wide viewing angle, the technical specifications of the XDMDK14A3 lend itself perfectly for applications requiring low power operation and light weight.

Some of the most common application fields for the XDMDK14A3 are message displays, clocks, counters, temperature indicators and display applications in industrial process controllers. Because of its simple to use interface, the LED display module can also be used for many embedded system applications requiring the display of text and numbers.

The XDMDK14A3 is designed to operate with low current and low power. Its low power operation allows the module to be operated using a single battery or via a regulated power supply. For example, when a 7V DC power supply is used, it consumes only 14 mA of current. This makes it ideal for battery powered or portable applications.

To control the display, the XDMDK14A3 features a two wire interface along with a selectable 4 or 8 character addressing scheme. Data is sent in the form of serial ASCII characters, the least significant bit being the first data bit. Once the data is sent, the module is ready to receive the next data byte.

The onboard control requires either an 8-bit or 4-bit data stream from an external controller. The interface includes serially addressable latch and data lines, along with an output enable and chip select line. Furthermore, the module includes a /STB pin that enables the user to start data transmissions from the beginning of the display.

Once data is sent to the module, the internal circuit generates the corresponding 7-segment pattern for the characters to be displayed. This is accomplished by the internal microprocessor and a series of shift registers. The generated pattern is then shifted through a series of transistors which drive the columns of the display.

The XDMDK14A3 is an efficient and cost effective option for all kinds of display applications, including message displays, clocks, counters, and temperature indicators. Its low power operation and lightweight design make it suitable for battery powered and portable applications. Onboard features, including two wire interface, 4 or 8 character addressing scheme, and easy to use external controller, along with its wide viewing angle and high brightness ensure the module is a top-of-the-line choice for any display application.
