Product data sheet Rev. 03 — 10 November 2008 5 of 44 NXP Semiconductors PCF8534A Universal LCD driver for low multiplex rates 6.2 Pin description [1] The substrate (rear side of the die) is wired to VSS but should not be electrically connected. 7. Functional description 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 Table 4. All of the display configurations can be implemented in the typical system shown in Figure 4. Table 3.
