(1) When an external crystal is used, oscillator (OSC_VSS, RTC_VSS) ground must be kept separate from other grounds and connected directly to the crystal load capacitor ground. These pins are shorted to VSS on the device itself and should not be connected to VSS on the circuit board. If a crystal is not used and the clock input is driven directly, then the oscillator VSS may be connected to board ground.
(2) Unless specifically indicated, these I/O specifications do not apply to USB I/Os. USB0 I/Os adhere to USB2.0 specification. USB1 I/Os adhere to USB1.1 specification.
(3) Whichever is smaller. P = the period of the applied signal. Maintaining transition times as fast as possible is recommended to improve noise immunity on input signals.

4.7 Notes on Recommended Power-On Hours (POH)

The information in the section below is provided solely for your convenience and does not extend or modify the warranty provided under TI’s standard terms and conditions for TI semiconductor products.

To avoid significant degradation, the device power-on hours (POH) must be limited to the following:

Table 4-1 Recommended Power-On Hours

Silicon Revision Speed Grade Operating Junction Temperature (Tj) Nominal CVDD Voltage (V) Power-On Hours [POH] (hours)
D 375 MHz 0 to 90 °C 1.2V 100,000
D 375 MHz -40 to 105 °C 1.2V 75,000(1)
D 375 MHz -40 to 125 °C 1.2V 20,000
D 456 MHz 0 to 90 °C 1.3V 100,000
D 456 MHz -40 to 90 °C 1.3V 100,000
(1) 100,000 POH can be achieved at this temperature condition if the device operation is limited to 345 MHz.

Note: Logic functions and parameter values are not assured out of the range specified in the recommended operating conditions.

The above notations cannot be deemed a warranty or deemed to extend or modify the warranty under TI’s standard terms and conditions for TI semiconductor products.
