CC3200 Power-on Hours

Jan Harman

There is specification "Power-on Hours" in the SWAS032E. Does it mean that if my product will be all the time in active mode (no time in sleep or hibernate mode), the reliability will fall after 17500 hours? It is only two years!

Thanks.

The 17500 hours is defined for the ON time only. Given that the OFF time is 80%, the number has to be scaled by a factor of 5x. Hence we get the 2x5 = 10 years.

OK, and my question was: if I have the device including nwp still ON, the reliability will fall down after two years?

Thanks

Is the chip only good for 17,500 hours of run time?

NWP On does not imply tha the device is in transmit mode. The TX cycle will depend upon the exact scenario being used. For an IDLE connected mode, the TX activity is negligible and hence you can expect the full device life time of 10+ years. For any high through-put activity like continuous uplink of data, you need to derate the life as per the duty cycle.

What are good methods of estimating on time for systems?
