See http://en.wikipedia.org/wiki/Operating_temperature.
Chips are normally specified for operation over one of these temperature ranges. Commercial grade chips are only specified down to 0 C, military and automotive much lower.
However- the CAMERA is only specified over a limited temperature range- for the D7000, for example, only down to 0 C. (This doesn't mean it won't work lower than that; just that it's not guaranteed by the manufacturer).
AND most of the time the camera and the chips inside do not actually reach the ambient temperature.
