Release Notes, IC Revision C
The replacement of A²SI Revision B with Revision C neither has any impact to required external components nor requires a change of the external circuitry. The CAP-Pin of an IC of Revision C shall be connected to a series of one capacitor and one resistor, in the same manner like on Revision B. Suggested values are C=4.7nF, R=430…680 Ohms. See the Data Sheet and the Application Notes for more detailed information.
