Power isolation during sensitive operations is disclosed. In one embodiment, a programmable chip package includes a programmable chip configured to perform a sensitive operation, and a switch configured to selectively couple a main power source to the programmable chip. The programmable chip package may also include an alternate power source and a controller that is configured to control the switch to decouple the main power source from the programmable chip prior to the sensitive operation, wherein the programmable chip is configured to draw power from the alternate power source during the sensitive operation. The controller is further configured to control the switch to couple the main power source to the programmable chip after the sensitive operation.
