Electrical Specifications
This chapter describes the AC and DC electrical specifications and thermal characteristics
for the MCF5407. Note that this information was correct at the time this book was
published. As process technologies improve, there is a likelihood that this information may
change. To confirm that this is the latest information, see Motorola’s ColdFire webpage,

20.1 General Parameters
Table 20-1 lists maximum and minimum ratings for supply and operating voltages and
storage temperature. Operating outside of these ranges may cause erratic behavior or
damage to the processor.
Table 20-2 lists junction and ambient operating temperatures.
