1 / 81 page  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 VLCD; an external VLCD is also possible N 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) N Generation of intermediate LCD bias voltage N Oscillator requires no external components I OTP calibration for VLCD 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 VDD1 to VSS: N 1.7 V to 3.3 V I High-voltage multiplier supply voltage range VDD2, VDD3 to VSS: N 1.8 V to 3.3 V I Display supply voltage range VLCD to VSS: N 3 V to 9 V PCF8811 80 x 128 pixels matrix LCD driver Rev. 04 — 27 June 2008 Product data sheet |
