The PCD8544 manufacture and develop by Philips Semiconductors commonly named Nokia 5110, a 84×84 LCD display with a low power CMOS LCD Controller driver designed to drive a graphic display at 48 rows and 84 columns can show 4 lines of characters . All required functions for the display are provided in a single chip including on-chip generation of LCD supply and BIAS VOLTAGE, resulting a minimum of external components and low power consumption. The Nokia 5110 LCD, PCD8544 interfaces to microcontrollers through Serial Bus Interface driven with the master microcontroller. The interface signal line reduced greatly , it has 8 signal line including power and ground. The LCD 5110 supports different types of microcontrollers such as Arduino, AVR, PIC, STM32, STC MSP430 and so on. Greatly it has a transfer rate up to 4Mbps can give full speed displaying the data without delay time.
