(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) These IO specifications apply to the dual-voltage IOs only and do not apply to the DDR2/mDDR . DDR2/mDDR IOs are 1.8V IOs and adhere to the JESD79-2A standard.
(3) Whichever is smaller. Where P = the period of the applied signal. Maintaining transition times as fast as possible is recommended to improve noise immunity on input signals.
(4) The RTC provides an option for isolating the RTC_CVDD from the CVDD to reduce current leakage when the RTC is powered independently. If these power supplies are not isolated (CTRL.SPLITPOWER=0), RTC_CVDD must be equal to or greater than CVDD. If these power supplies are isolated (CTRL.SPLITPOWER=1), RTC_CVDD may be lower than CVDD.
(5) DVDD18 must be powered even if all of the DVDD3318_x supplies are operated at 3.3V.

5.4 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 5-1 Recommended Power-On Hours

Silicon Revision Speed Grade Operating Junction Temperature (Tj) Nominal CVDD Voltage (V) Power-On Hours [POH] (hours)
B/E 300 MHz 0 to 90 °C 1.2V 100,000
B/E 375 MHz 0 to 90 °C 1.2V 100,000
B/E 375 MHz -40 to 105 °C 1.2V 75,000(1)
B/E 456 MHz 0 to 90 °C 1.3V 100,000
B/E 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.
