PCA8547

4 x 44 automotive LCD driver with integrated charge pump

Rev. 2 — 7 April 2015

Product data sheet

1. General description

The PCA8547 is a fully featured Liquid Crystal Display (LCD)¹driver, specifically designed

for high-contrast Vertical Alignment (VA) LCD with multiplex rates up to 1:4. It generates

the drive signals for any static or multiplexed LCD containing up to four backplanes,

44 segments, and up to 176 elements. The PCA8547 features an internal charge pump

with internal capacitors for on-chip generation of the LCD driving voltage. To ensure an

optimal and stable contrast over the full temperature range, the PCA8547 offers a

programmable temperature compensation of the LCD supply voltage. The PCA8547 can

be easily connected to a microcontroller by either the two-line I²C-bus (PCA8547A) or a

three-line bidirectional SPI-bus (PCA8547B).

For a selection of NXP LCD segment drivers, see Table 43 on page 66.

2. Features and benefits

 AEC Q100 compliant for automotive applications.

 Low-power single-chip LCD controller and driver

 176 elements allowing to drive:

 up to 22 7-segment alphanumeric characters

 up to 11 14-segment alphanumeric characters

 Selectable backplane drive configuration: static, 2, or 4 backplane multiplexing

 Software programmable internal charge pump for on-chip LCD voltage generation up

to 9 V with internal capacitors

 400 kHz I²C-bus interface (PCA8547A)

 5 MHz SPI-bus interface (PCA8547B)

 Programmable temperature compensation of V_LCDwith both, negative and positive

slopes in four temperature regions

 Selectable display bias configuration

 Wide range for digital power supply: from 1.8 V to 5.5 V

 Wide LCD supply range: from 2.5 V for low threshold LCDs and up to 9.0 V for high

threshold twisted nematic LCDs

 On-chip RAM for display data storage arranged in two banks

 Display memory bank switching

 Programmable frame frequency in the range of 60 Hz to 300 Hz in steps of 10 Hz;

factory calibrated

 Integrated temperature sensor with temperature readout

 On chip calibration of internal oscillator frequency and V_LCD
