It, too, has pins that allow it to be mounted quickly and easily. 6 different optional LED backlights are available. These can be combined with 5 different display technologies, making it possible to have up to around 20 different designs. Designed for compact, handheld devices, this modern LCD series offers a number of benefits with and without backlighting: * Extremely compact (55x31 mm) with a large viewing area of 51x15 mm * Super-flat: 2.0 mm without backlight module, and only 5.8 mm with a b./l. module mounted * Serial SPI interface (4-wire) * Single supply +2.4 V or +3.3 V * Typical power consumption of only 140A in full operation (white LED backlight from 5mA) * Easily mounted by soldering * Wide range of design variants orderable as single units * Backlighting color changes possible CONTRAST ADJUSTMENT The contrast can be set by means of a command for all the displays in the EA DOGM series. The contrast setting of the display must be set once by the software, and is then kept constant throughout the entire operating temperature range (20..+70C), thanks to the integrated temperature compensation. LED BACKLIGHT 6 different variants are available for individual backlighting: white, yellow/ green, blue, red, amber and a full-color version. There are 2 separate LED paths available for each monochrome backlight that can be switched in parallel or in series to suit the system voltage. This means that most backlights can be run at either 3.3 V or 5 V. To operate the backlight, we recommend a current source (e.g. CAT4238TD) or an external series resistor to limit the current. This can be calculated from R=U/I; you can find the values in the table on the right. To prolong the life of the backlights, we recommend that you use a current source. The operating life of the yellow/green, red and amber backlights is 100,000 hours. The life of the white and blue backlights is considerably shorter. We recommend that you dim these or switch them off whenever possible. Important: Never connect the backlight LEDs directly to a 5 V/ 3.3 V supply as this will immediately destroy the LEDs. Always use a current source. Please note that derating applies at temperatures exceeding +25C.

EA DOGM132-5 Page 5 TABLE OF PROGRAMMING COMMANDS DATA TRANSFER Data transfer is unidirectional. That means that data can only be written; it cannot be read again. In contrast to other displays, a busy query is not necessary with this display. The clock-pulse rate of the SCL line can be up to 20 MHz @3.3V, depending on the supply voltage. You will find more detailed information on timing on pages 64 and 65 of the data sheet of the ST7565R controller, which you will find on our website at http://www.lcd-module.de/eng/pdf/zubehoer/st7565r.pdf ELECTRONIC ASSEMBLY reserves the right to change specifications without prior notice.

EA DOGM132-5 Page 7 12:00 VIEWING ANGLE, TOP VIEW OPTION If the display is read mostly from above (on the front of a laboratory power supply unit, for example), the preferred angle of viewing can be set to 12 o'clock. This rotaties the display by 180.A slightly different initialization setup is required for this. Also keep in mind that the leftmost column (normally numbered as 0) will now change to 4.

The preview function shows immediately the size and style in simulation window. When the testboard EA 9780-2USB is connected to the USB port, you can see the character (or any predefined text) live on the display ! No need to say that the export function generates a C- and Basic source code as an include file to your software. Included is also a software that is called BitmapEdit. With that it becomes easy to convert standard *.bmp files into the EA DOGM132-5 format. USB-TEST BOARD EA 9780-2USB For easy startup, a USB test board is available that can be connected to a PC. A USB cable and Windows software is supplied with the product. This allows text and images (*.bmp) to be displayed directly on the connected display. You will find more information on the test board in the EA 97802USB data sheet. SIMULATION WITH WINDOWS A simulator window also displays the contents of the display. The software can simulate all the displays and colors even without the hardware.

Note: - LC displays are generally not suited for wave or reflow soldering. Temperatures of over 80C can cause lasting damage. - The surfaces of the displays and backlights are protected from scratching by self-adhesive protective foils. Please remove these before mounting. - Make sure that either display nor backlight will never come into contact with any kind of liquid like Fluxer, Cleaner, Water. ATTENTION DIMENSIONS EA LED55X31 handling precautions! Note: The 4 LED pins A1/A2 and C1/C2 also have to be soldered from above to ensure good contact. all dimensions are in mm Zeppelinstrasse 19 * D-82205 Gilching * Phone +49-(0)8105-778090 * Fax: +49-(0)8105-778099 * www.lcd-module.de * info@lcd-module.de
