The NXP PCA8539 is a single-chip LCD driver that generates
the drive signals for any segmented LCD with up to 1 800
elements, a dot matrix LCD with up to 18 rows and 100
columns, or any combination of dot matrix with icons.
Suitable for use with a wide range of LCDs, it features an
internal charge pump with internal capacitors for on-chip
generation of an LCD supply of up to 16 V.
The driver features an internal oscillator that governs data flow
from the internal RAM to the display.
The PCA8539 communicates via the two-line I2C-bus (up to
To ensure optimal and stable contrast over the entire
temperature range, the PCA8539 includes advanced
temperature compensation of VLCD with six programmable
temperature regions and eight programmable slopes in each
region.
400 kHz) or the four-line SPI-bus (up to 3 MHz).
The serial interface is selectable through an input pin.
