Power Dissipation

This table provides preliminary, estimated power dissipation for various configurations. Note that suitable

thermal management is required to ensure the junction temperature does not exceed the maximum

specified value. Also note that the I/O power should be included when determining whether to use a heat

sink. For a complete list of possible clock configurations, see Section 7, “Clock Configuration Modes.”

3 Values do not include I/O. Add the following estimates for active I/O based on the following bus speeds:

66.7 MHz = 0.35 W (nominal), 0.4 W (maximum)

83.3 MHz = 0.4 W (nominal), 0.5 W (maximum)

100 MHz = 0.5 W (nominal), 0.6 W (maximum)

133 MHz = 0.7 W (nominal), 0.8 W (maximum)
