Product data sheet
1. 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
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, resulting in a
minimum of external components and low power consumption. The PCF8811 can
interface microcontrollers via a parallel bus, serial bus or I²C-bus interface.
2. Features
I Single-chip LCD controller/driver
I 80 row and 128 column outputs
I Display data RAM 80 × 128 bit
I 128 icons (row 80 can be used for icons in extended command set and when icon rows
are enabled)
I Low power consumption; suitable for battery operated systems
I An 8-bit parallel interface, 3 or 4-line Serial Peripheral Interface (SPI) and high-speed
I²C-bus
I On-chip:
N Configurable voltage multiplier generating LCD supply voltage V_LCD; an external
V_LCD is also possible
N Linear temperature compensation of V_LCD; 8 programmable temperature
coefficients (extended command set); one fixed temperature coefficient which can
be set as default by OTP programming (basic command set)
N Generation of intermediate LCD bias voltage
N Oscillator requires no external components
I OTP calibration for V_LCD and accurate frame frequency
I External reset input pad
I External clock input possible
I Multiplex 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
I Logic supply voltage range V_DD1 to V_SS:
N 1.7 V to 3.3 V
I High-voltage multiplier supply voltage range V_DD2, V_DD3 to V_SS:
N 1.8 V to 3.3 V
I Display supply voltage range V_LCD to V_SS:
N 3 V to 9 V
