× 102 pixels matrix LCD driver

PCF8813

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 and1:68

• 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

• Portable instruments

• Point of sale terminals.

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.
