The PCA8534A is a peripheral device which interfaces to almost any Liquid Crystal
Display (LCD)
multiplexed LCD containing up to four backplanes and up to 60 segments. It can be easily
cascaded for larger LCD applications. The PCA8534A is compatible with most
microprocessors or microcontrollers and communicates via a two-line bidirectional
I
auto-incremented addressing, by hardware subaddressing, and by display memory
switching (static and duplex drive modes).
AEC-Q100 compliant for automotive applications.
