(6) Assumes the following conditions: 60% CPU utilization; DDR2 at 50% utilization (250 MHz), 50% writes, 32 bits, 50% bit switching; two
2-MHz McBSPs at 100% utilization, 50% switching; two 75-MHz Timers at 100% utilization; device configured for HPI32 mode with
pull-up resistors on HPI pins; room temperature (25 ° C). The actual current draw is highly application-dependent. For more details on
core and I/O activity, see the TMS320C6455/54 Power Consumption Summary application report (literature number SPRAAE8 ).
