Figure 15: Principle application example. iC-PVL as battery powered multiturn counter, e.g. in a metering
application. Interface operating in INT_MODE = 0, read-out of the internal counter value via SSI
or I²C. VDD supply is only needed during read-out, otherwise iC-PVL is battery-powered. Direct
access to iC-PVL EEPROM via SCL, SDA.
Note: All circuit examples shown in this chapter are principle wiring diagrams. Further components may be
necessary but are omitted for clarification of the application principle.
