It uses the PCD8544 controller. The PCD8544 is a low power CMOS LCD controller/driver, designed to drive a graphic display of 48 rows and 84 columns. All necessary functions for the display are provided in a single chip, including on-chip generation of LCD supply and bias voltages, resulting in a minimum of external components and low power consumption. The PCD8544 interfaces to microcontrollers through a serial bus style interface.

Note: Do not connect the LED pin (8) directly to 5VDC as it will damage the backlight LEDs (hook up to 3.3V in the pic above). While rest of the LCD does seem to work off 5VDC power and signals from an Arduino, please keep in mind that this may diminsh the life of the LCD. It is recommend that you use a 3.3V power and a 3.3V based Microcontroller with this graphic LCD and use current limiting for the LED backlight. An alternative is to use logic level convertors with 5V TTL microcontrollers.
