(67 + 1) × 102 pixels matrix LCD driver
Product specification
PCF8813
1 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.
2 APPLICATIONS
• Telecom equipment
• Portable instruments
• Point of sale terminals.
3 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.
