The PmodRTCC is a Real-Time Clock/Calendar powered by the Microchip MCP79410.

The PmodRTCC can communicate using I²C via the 8-pin header J2. Digilent boards implement several different I²C interfaces and they are outlined in the “Connecting TWI Interfaces” document. The multi-function pin can be accessed via the two pin header J1.
