Using PCD8544 5110 CMOS 48x84 LCD
Today, we will examine the LCD panel with the PCD8544 microcontroller chip. This LCD is an LCD screen used as an indicator in many electronic systems. This screen (5110), which was used as the screen of a mobile phone brand, is still used in many systems today.
It has the dimensions of 48 pixel rows and 84 pixels columns. It works with 2.7 Volt-3.3 Volt supply. The functions of the pins of the LCD screen are listed below.
- RST --------- Reset
- CE ------------ Chip selection
- D/C ----------- Data/Command selection
- DIN -----------Serial data line (Serial interface speed 4.0 Mbits/s)
- CLK ------------ Serial clock
- 3.3V ------------ VCC
- Light --------- Backlight control terminal
- GND ----------- Powernegative
Description of pins:
Logic 0 is sent to the RST pin to reset the display.
Logic 0 is sent to the CE pin to activate the chip.
If logic 1 is sent to the D/C pin, data is written to the screen. If logic 0 is sent, the command is sent.
DIN is the data input pin. Pixel data should be given in series from this pin. Data is sent in sync with the clock applied to the CLK pin. As stated above, the maximum speed is 4.0 Mbits/s.
The 3.3 Volt pin is the 3.3 volt voltage input terminal.
The light pin input is used for LCD lighting.
