GENERAL DESCRIPTION
The PCF8811 is a low power CMOS LCD controller driver, designed to drive a graphic display of 80 rows and 128 columns or a graphic display of 79 rows and 128 columns and a icon row of 128 symbols. All necessary

FEATURES
• Single-chip LCD controller/driver
• 80 row and 128 column outputs
• Display data RAM 80×128 bits
• 128 icons (row 80 can be used for icons in extended command set and when icon rows are enabled)
• An 8-bit parallel interface, 3 or 4-line Serial Peripheral Interface (SPI) and high-speed I2C-bus
• On-chip:
  – Configurable voltage multiplier generating VLCD;
external VLCDalso possible
  – Linear temperature compensation of VLCD;
    8 programmable temperature coefficients (extended command set); one fixed temperature coefficient which default can be set by OTP programming (basic command set)
  – Generation of intermediate LCD bias voltage
  – Oscillator requires no external components; external clock input also possible.
• OTP calibration for VLCDand accurate frame frequency
• External reset input pin
• CMOS compatible inputs
• Mux rate: 1 : 16 to 1 : 80 in steps of 8 when no icon row is used, with the icon row steps of 16 can be used
• Logic supply voltage range VDD1−VSS:
  – 1.7 V to 3.3 V.
• High voltage generator supply voltage range VDD2,VDD3−VSS:
  – 1.8 V to 3.3 V.
• Display supply voltage range VLCD−VSS:
  – 3Vto9V.
• Low power consumption; suitable for battery operated systems
• Programmable bottom row pads mirroring; for compatibility with both Tape Carrier Packages (TCP) and Chip On Glass (COG) applications (extended command set)
• Status read which allows for chip recognition and content checking of some registers
• Start address line which allows, for instance, the scrolling of the displayed image
• Programmable display RAM pointers for variable display sizes
• Slim chip layout, suited for COG applications
• Temperature range: Tamb=−40°C to +85°C.

APPLICATIONS
• Telecom equipment
• Portable instruments
• Point of sale terminals.
