The definition of the abbreviations and acronyms used in this data sheet can be found in
The PCA85162 is a peripheral device which interfaces to almost any Liquid Crystal
Display (LCD)
multiplexed LCD containing up to four backplanes and up to 32 segments. It can be easily
cascaded for larger LCD applications. The PCA85162 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.
