PPC405EX – PowerPC 405EX Embedded Processor
Power Control
This chip has power management control to put the following functional units to sleep if not needed. The typical
and maximum power consumption for the each of these units is:
Table 17. Power Contribution of Functional Units
Test Conditions
Clock timing and switching characteristics are specified in accordance with minimum
operating conditions shown in the table “Recommended DC Operating Conditions” on
page 48. For all signals, AC specifications are characterized at T
load shown in the figure to the right.
