1 FEATURES
PCF8811
· 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 to 3.3 V. · High voltage generator supply voltage range VDD2 VDD3 - VSS: 1.8 to 3.3 V. · Display supply voltage range VLCD - VSS: 3 to 9 V. · Low power consumption; suitable for battery operated systems 4 ORDERING INFORMATION PACKAGE TYPE NUMBER NAME PCF8811U/2DA/1 PCF8811MU/2DA/1 - - DESCRIPTION chip with bumps in tray, not covered under Philips/Motif license agreement chip with bumps in tray, sold under license from Motif VERSION - - · Programmable bottom row pads mirroring; for compatibility with both Tape Carrier Packages (TCP) and Chip On Glass (COG) application (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 °C. 2 APPLICATIONS
· Telecom equipment · Portable instruments · Point of sale terminals. 3 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.
