The PCF8811 is a low-power CMOS LCD controller and driver. It is designed to drive a
graphic display of 80 rows and 128 columns or of 79 rows, 128 columns, and an 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. Therefore only a
minimum of external components are required and power consumption is low. The
PCF8811 can interface microcontrollers via a parallel bus, serial bus, or I²C-bus interface.
128 icons (in extended command set row 79 can be configured for displaying icons)
Low power consumption; suitable for battery operated systems
Interfaces:
8-bit parallel
3- or 4-line Serial Peripheral Interface (SPI)
High-speed I²C-bus
Configurable voltage multiplier generating LCD supply voltage VLCD; an external VLCD
is also possible
Linear temperature compensation of VLCD:
8 programmable temperature coefficients (extended command set)
one fixed temperature coefficient which can be set as default by OTP programming
(basic command set)
Generation of intermediate LCD bias voltage
Oscillator requires no external components
OTP calibration for VLCD and accurate frame frequency
External reset input pin
External clock input possible
Multiplex rate 1:16 to 1:80 selectable
in steps of 8 when icon row is not used
in steps of 16 when the icon row is used
Logic supply voltage range VDD1 to VSS:
1.7 V to 3.3 V
High-voltage multiplier supply voltage range VDD2, VDD3 to VSS:
1.8 V to 3.3 V
Display supply voltage range VLCD to VSS:
3 V to 9 V
Programmable bottom row pins 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
