The PCF8534A is a versatile peripheral device designed to interface any microprocessor
or microcontroller to a wide variety of LCDs. It can directly drive any static or multiplexed
LCD containing up to four backplanes and up to 60 segments.
The display configurations possible with the PCF8534A depend on the number of active
backplane outputs required. Display configuration selection is shown in
display configurations can be implemented in the typical system shown in
