Technical summary
The Nokia 5110 is a basic graphic LCD screen for many applications. It uses the PCD8544 controller, which is the same one used in the Nokia 3310 LCD. All the functions necessary for the display are provided in a single chip, including on-chip generation of the LCD supply and bias voltages, resulting in a minimum of external components and low power consumption.
The four corners all have a positioning hole, providing upper and lower ports on both rows at the same time, the arrangement is as follows:
1 RST - reset
2 CE - CS
3 DC - data / instruction select
4 DIN - serial data line
5 CLK - serial clock line
