GLCD5110 Graphic LCD module l 1
GLCD5110
Graphic LCD 84x48 pixel
Technical features
l Graphic LCD module # LPH7366. Resolution is 84 x 48 pixel. l Built-in PCD8544 controller with SPI interface bus. l Built-in the backlight blue LED controlled by software l Supply voltage range is +3 to +3.3V. Maximum current is 10mA (with backlight
LED)
l Display the standard size 5x7 pixel character up to 14 characters 6 lines and
mono-tone graphic image.
l Size is 4.5 x 4.5 cm. l Easy to connection l Interface with any popular microcontroller.
- If interface with +3V logic system, user can connect GLCD with microcontroller port directly. - If interface with +5V system, user must connect through the attenuator circuit for redeuce the logic level from +5V to +3 or +3.3V or not over the supply voltage of GLCD5110.
The figure 1 shows size and pin assignment of GLCD5110. The figure 2 shows the interfacing circuit with the microcontroller and figure 3 shows the simple attenuator circuit for interfacing GLCD5110 with +5V microcontroller system.
