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)
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 I
2
C-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
