â All typical values are at VDD = 5 V, TC = 25°C.
â¡ All input and output voltage levels except RS, INT0 â INT3, NMI, CNT, X2/CLKIN, CLKMD0 â CLKMD3 are TTL-compatible.
§ Clock mode: PLL à 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 TMS320C54x Power Dissipation application report (literature number SPRA164).
