† All values are typical unless otherwise specified.
‡ All revisions of the ’5402 can be operated with an external clock source, provided that the proper voltage levels be driven on the X2/CLKIN pin.
It should be noted that the X2/CLKIN pin is referenced to the device 1.8V power supply (CVdd), rather than the 3V I/O supply (DVdd). Refer to
the recommended operating conditions section of this document for the allowable voltage levels of the X2/CLKIN pin.

# 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 McBSP0 and McBSP1 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 TMS320C54x Power Dissipation Application Report (literature number SPRA164).
