PCA8543  
4 x 60 automotive LCD segment driver with integrated charge  
pump  
Rev. 1 — 21 January 2014  
Product data sheet  
1. General description  
The PCA8543 is a peripheral device which interfaces to almost any Liquid Crystal Display  
(LCD)1 with low multiplex rates. It generates the drive signals for any static or multiplexed  
LCD containing up to four backplanes, 60 segments, and up to 240 elements. The  
PCA8543 is compatible with most microcontrollers and communicates via the two-line  
bidirectional I2C-bus. Communication overheads are minimized using a display RAM with  
auto-incremented addressing and display memory switching. The PCA8543 features an  
internal charge pump with internal capacitors for on-chip generation of the LCD driving  
voltages.  
For a selection of NXP LCD segment drivers, see Table 40 on page 59.  
2. Features and benefits  
AEC Q100 grade 2 compliant for automotive applications  
Low power consumption  
Extended operating temperature range from 40 C to +105 C  
60 segments and 4 backplanes allowing to drive:  
up to 30 7-segment alphanumeric characters  
up to 15 14-segment alphanumeric characters  
any graphics of up to 240 elements  
Selectable backplane drive configuration: static, 2, or 4 backplane multiplexing  
Programmable internal charge pump for on-chip LCD voltage generation up to  
3 VDD2  
400 kHz I2C-bus interface  
Selectable linear temperature compensation of VLCD  
Selectable display bias configuration  
Wide range for digital and analog power supply: from 2.5 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 (automobile) twisted nematic LCDs  
On-chip RAM for display data storage arranged in two banks  
Display memory bank switching  
Programmable frame frequency in steps of 10 Hz in the range of 60 Hz to 300 Hz;  
factory calibrated with a tolerance of 15 % covering the whole temperature and  
voltage range  
Selectable inversion scheme for LCD driving waveforms: frame or line inversion
