× 128 pixels matrix LCD driver

PCF8811

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 VLCD also 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 VLCD and 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.

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

functions 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 PCF8811 can interface

to microcontrollers via a parallel bus, serial bus or I2C-bus

interface.
