GENERAL DESCRIPTION

The PCF8813 is a low power CMOS LCD controller driver designed to drive a graphic display of 67 rows and 102 columns plus an icon row of up to 102 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 PCF8813 can interface to microcontrollers via a parallel, serial or I2C-bus interface.

FEATURES

? Single-chip LCD controller or driver

? 67 row + 1 icon row, 102 column outputs (the icon row is available twice to allow icons to be displayed at the top or at the bottom of the display)

? Very low power consumption, optimized for battery operated systems

? On-chip:

– Display data RAM 68 × 102 bits

– Configurable voltage multiplier (× 5, × 4, × 3 and × 2) generating highly accurate VLCD and includes booster capacitors (external VLCD is also possible)

– Temperature compensation of VLCD with four selectable temperature coefficients

– Generation of intermediate LCD bias voltages

– Highly-accurate built-in oscillator requiring no external components (an external clock is also possible)

? High integration level resulting in minimum number of external capacitors and resistors

? Selectable 8-bit parallel interface, 3-line or 4-line Serial Peripheral Interface (SPI), 3-line serial interface and high-speed I2C-bus interface

? External reset input

? CMOS compatible inputs

? Mux rates: 1 : 9 to 1 : 65 in steps of 8 and 1 : 68

? Logic supply voltage range 1.7 to 3.3 V

? High voltage generator supply voltage range 2.4 to 4.5 V

? Display supply voltage range 3.0 to 9.0 V

? One Time Programmable (OTP) VLCD trimming

? Horizontal and vertical mirroring

? Status read which allows chip recognition and content checking of some registers

? Start address line which allows, for instance, scrolling of the displayed image

? Programmable display RAM pointers for various display sizes

? Slim chip layout optimized for chip-on-glass applications

? Operating temperature range ?40 to +85 °C

? Very close tolerance on VLCD and frame frequency for excellent optical performance

? Support for LCD cell tolerance compensation of VLCD by OTP storage.

APPLICATIONS

? Telecom equipment
