Printing and typographical errors reserved. EA DOGM132-5 Page 2 EA DOGM132 The EA DOGM132, a 132x32-pixel graphics display, is a new addition to ELECTRONIC ASSEMBLY’s EA DOGM series. 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 140µA 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..+70°C), 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. Limiting resistor yellow/green EA LED55x31-G Forwar voltage Current max. @ 3,3 V @5V 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. Connected in parallel 2,2 V 80 mA 14 ohm 35 ohm Connected in series 4,4 V 40 mA - 15 ohm white EA LED55x31-W Forwar voltage Current max. @ 3,3 V @5V 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. Connected in parallel 3,2 V 60 mA 1,6 ohm 30 ohm Connected in series 6,4 V 30 mA - - blue EA LED55x31-B Forwar voltage Current max. @ 3,3 V @5V Connected in parallel 3,2 V 60 mA 1,6 ohm 30 ohm Connected in series 6,4 V 30 mA - - amber EA LED55x31-A Forwar voltage Current max. @ 3,3 V @5V 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 +25°C. Connected in parallel 2,4 V 80 mA 11 ohm 32 ohm Connected in series 4,8 V 40 mA - 5 ohm red EA LED55x31-R Forwar voltage Current max. @ 3,3 V @5V ASSEMBLING Connected in parallel 2,1 V 80 mA 15 ohm 36 ohm Connected in series 4,2 V 40 mA - Limiting resistor Limiting resistor Limiting resistor Limiting resistor 20 ohm First, clip the display and backlight modules together by gently pushing the display pins through the corresponding holes on the backlight Limiting resistor Full color Forwar Current module. Then insert the entire module into the socket, or into the EA LED55x31-RGB voltage max. @3,3 V @5V soldering holes on the pcb. The backlight pins (the 2 rows with 3 pins Connected in parallel 4V 125 mA 3x24 ohm at the bottom) must be soldered on the top side as well to ensure good contact between the modules. Important: The display has a protective film on the top and/or the bottom, and there is also one on the backlight. These must be removed. Make sure that neither display nor backlight will never come into contact with any kind of liquid like Fluxer, Cleaner, Water.

Current consumption typ. 110uA WIDE RANGE The operation on +2.4..+3.3V (single supply) requires 9 external capacitors. Current consumption is typ. 150uA. LOW VOLTAGE If an external source of +9..+12V (does not have to be stabilized) is available, the charge pump is not needed and less external components are required. Supply and logic voltage may be 1.8..3.3V ELECTRONIC ASSEMBLY reserves the right to change specifications without prior notice. Printing and typographical errors reserved. 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.

Note: - LC displays are generally not suited for wave or reflow soldering. Temperatures of over 80°C 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.
