Power Dissipation
Table 7 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, refer to Section 7, “Clock Configuration

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)
