Power Fail Logger Optimized for no power at the AC plug 

 Automatic switching to battery on main power loss.

Data Sheet https://www.nxp.com/docs/en/ 

Features
 SPI bus SD Card for data logging power outages
 I2C bus for Real Time Clock with date and time
 Time Stamp provides year, month, day, hours, minutes, seconds 
 Automatic switching to battery on main power loss. 
 Captures Power Failures with time and date stamp written to SD Card.
 Captures Power Restored with time and date stamp written to SD Card.
 Captures system resets with time and date stamp written to SD Card.  
 
 Three time log registers triggered from battery switch-over as well as input driven events.
 Featuring clock output and two independent interrupt signals.
 ISP interface uses USBTiny
 SPI Interface 
 I2C interface
 16-MHZ Crystal Clock.
