PCA9620

60 x 8 LCD high-drive segment driver for automotive and

industrial

Rev. 3 — 3 July 2013

Product data sheet

1. General description

The PCA9620 is a peripheral device which interfaces to almost any Liquid Crystal Display

(LCD)¹with 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

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 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  V_DD2

 400 kHz I²C-bus interface

 Selectable linear temperature compensation of V_LCD

 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 V_LCD
