(1) Assumes the following conditions: 25°C case temperature; 60% CPU utilization; EMIF at 50% utilization (100 MHz), 50% writes,
(32 bits), 50% bit switching; two 10-MHz SPI at 100% utilization, 50% bit switching.
The actual current draw is highly application-dependent. For more details on core and I/O activity, refer to the TMS320C672x Power
Consumption Summary Application Report (literature number SPRAAA4).

(1) See the absolute maximum ratings and the recommended operating conditions.
(2) Silicon operating life design goal is 10 years at 105°C junction temperature (does not include package interconnect life).
(3) The predicted operating lifetime vs junction temperature is based on reliability modeling using electromigration as the dominant
failure mechanism affecting device wearout for the specific device process and design characteristics.
