General Description: 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 interface. The PCD8544 is manufactured in n-well CMOS
technology.
