PCA8539
100 x 18 Chip-On-Glass automotive LCD dot matrix driver
Rev. 2 — 12 September 2014
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/segments. 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 I
2
C-bus or a four-line bidirectional
SPI-bus.
For a selection of NXP LCD graphic drivers, see
Table 50 on page 86.
