All values are typical unless otherwise specified.
All input and output voltage levels except RS, INT0−INT3, NMI, X2/CLKIN, CLKMD1−CLKMD3 are LVTTL-compatible.
HPI input signals except for HPIENA.
Clock mode: PLL × 1 with external source
This value was obtained with 50% usage of MAC and 50% usage of NOP instructions. Actual operating current varies with program being
executed.

This value was obtained with single-cycle external writes, CLKOFF = 0 and load = 15 pF. For more details on how this calculation is performed,
refer to the Calculation of TMS320LC54x Power Dissipation application report (literature number SPRA164).
