Notes: No Specifications for Min/Max PL1/PL2 values. Hardware default of PL1 Tau=1s, By including the benefits available from power and thermal management features the recommended is to use PL1 Tau=28s for less than 45W. PL2- Processor opportunistic higher Average Power – Reactive, Limited Duration controlled by Tau_PL1 setting. PL1 Tau - PL1 average power is controlled via PID algorithm with this Tau, The larger the Tau, the longer the PL2 duration. System cooling solution and designs found to not being able to support the Performance TauPL1, adjust the TauPL1 to cooling capability.

Notes: The thermal solution needs to ensure that the processor temperature does not exceed the Processor temperature range. The Tj used to define U processor base power is 100°C. The Tj used to define U Type4 processor base power is 90°C. Operating the part at Tj_max (110°C) Is feasible but may result in slightly higher power than Processor Base Power. Thermal designs, if desired, can program a TCC Offset and Tau value to limit the processors operational Tj. The processor junction temperature is monitored by Digital Temperature Sensors (DTS). For DTS accuracy, refer to Digital Thermal Sensor
