10.2. Fastest Operating Frequency as a Function of Temperature
The following graph represents a small sample average of a Propeller chip’s fastest operating range. The test was performed
in a forced air chamber using code run on all eight cogs, multiple video generators, and counter modules. A frequency was
considered successful if the demo ran without fault for one minute. The curves represent an aggressive testing procedure
(averaged, forced air, one minute time limit); therefore the designer must de-rate the curve to arrive at a stable frequency for a
particular application. Again the grayed regions represent temperatures beyond the military temperature range.
