MCP7940M I²C Real-Time Clock/Calendars
The Microchip MCP7940M is Real-Time Clock Calendar (RTCC) that supports I²C communications. The MCP7940M includes a digital trimming circuit for accuracy which can compensate for crystal tolerance and temperature.
The MCP7940M features a multi-functional output that can be configured as an alarm output, to output a selectable frequency square wave or as a general purpose output.
