PCA9620  
Universal LCD driver for low multiplex rates  
Rev. 1 — 9 December 2010  
Product data sheet  
1. General description  
The PCA9620 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 eight backplanes, 60 segments, and up to 480 elements. The  
PCA9620 is compatible with most microprocessors or microcontrollers and communicates  
via a two-line bidirectional I2C-bus. Communication overheads are minimized using a  
display RAM with auto-incremented addressing and display memory switching. The  
PCA9620 features an internal charge pump with internal capacitors for on-chip generation  
of the LCD driving voltages.  
AEC Q100 grade 2 compliant for automotive applications.  
2. Features and benefits  
„ Low power consumption  
„ Extended operating temperature range from −40 °C to +105 °C  
„ 60 segments and 8 backplanes allowing to drive:  
‹ up to 60 7-segment alphanumeric characters  
‹ up to 30 14-segment alphanumeric characters  
‹ any graphics of up to 480 elements  
„ 480 bit RAM for display data storage  
„ Selectable backplane drive configuration: static, 2, 4, 6, or 8 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  
„ Display memory bank switching in static, duplex, and quadruplex drive modes  
„ 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  
„ Integrated temperature sensor with temperature readout  
„ On chip calibration of internal oscillator frequency and VLCD
