§ Clock mode: PLL × 1 with external source
This value represents the current consumption of the CPU, on-chip memory, and on-chip peripherals. Conditions include: program execution from
on-chip RAM, with 50% usage of MAC and 50% usage of NOP instructions. Actual operating current varies with program being executed.
# This value was obtained using the following conditions: external memory writes at a rate of 20 million writes per second, CLKOFF=0, full-duplex
operation of all three McBSPs at a rate of 10 million bits per second each, and 15-pF loads on all outputs. For more details on how this calculation
is performed, refer to the Calculation of TMS320LC54x Power Dissipation Application Report (literature number SPRA164).
The following load circuit in Figure 51 was used on all outputs pins and I/O pins in input mode. All timing
measurements in this data sheet were measured from the 5409 connection to the following load circuit.
