PCA8539  
100 x 18 Chip-On-Glass automotive LCD dot matrix driver  
Rev. 1 — 11 November 2013  
Product data sheet  
1. General description  
The PCA8539 is a fully featured Liquid Crystal Display (LCD)1 driver, specifically designed  
for high-contrast Vertical Alignment (VA) LCD with multiplex rates up to 1:18. It generates  
the drive signals for multiplexed LCD containing up to 18 backplanes, 100 segments, and  
up to 1800 elements. The PCA8539 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 PCA8539 offers a programmable  
temperature compensation of the LCD supply voltage. The PCA8539 can be easily  
connected to a microcontroller by either the two-line I2C-bus or a four-line bidirectional  
SPI-bus.  
For a selection of NXP LCD graphic drivers, see Table 46 on page 81.  
2. Features and benefits  
AEC Q100 grade 2 compliant for automotive applications  
Single-chip LCD controller and driver  
Extended operating temperature range from 40 C to +105 C  
100 segments and 18 backplanes allowing to drive any graphic with up to 1800  
elements  
On-chip:  
Configurable 4, 3, or 2 times voltage multiplier generating LCD supply voltage,  
independent of VDD, programmable by instruction (external supply also possible)  
Integrated temperature sensor with temperature readout  
Temperature compensation of on-chip generated VLCDOUT. Selectable linear  
temperature compensation of VLCD  
Generation of intermediate LCD bias voltages  
Oscillator requires no external components (external clock also possible)  
Readout of RAM and registers possible  
Diagnostic features:  
Checksum on I2C and SPI bus  
Frame frequency: programmable from 45 Hz to 360 Hz  
2960-bit RAM for storage (1800 bit for display data)  
Two-line I2C-bus interface or four-line SPI bus  
Multiplex drive mode 1:18 and 1:12  
Inversion modes  
n-line (n = 1 to 7) inversion
