PCF8811U 80 x 128 pixels matrix LCD driver

The PCF8811 is a low-power CMOS1LCD controller and 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

产品特点 Features
  • Single-chip LCD controller and driver
  • 80 row and 128 column outputs
  • Display data RAM 80 × 128 bit
  • 128 icons (row 80 can be used for icons in extended command set and when icon rows are enabled)
  • Low power consumption; suitable for battery operated systems
  • Interfaces: an 8-bit parallel interface, 3 or 4-line Serial Peripheral Interface (SPI) and High-speed I²C-bus
  • On-chip:
    • 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 pad
  • External clock input possible
  • 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
  • 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 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 ℃ to +85 ℃
