Notes:
All specifications in this table are based on estimates and simulations or empirical data. These specifications will be updated with characterized data from silicon measurements at a later date.
Long term reliability cannot be assured in conditions above or below Maximum/Minimum functional limits.
The voltage specification requirements are measured on capacitors pads near to the package, with an oscilloscope set to 100 MHz bandwidth, 1.5 pF maximum probe capacitance, and 1 MΩ minimum impedance. The maximum length of ground wire on the probe should be less than 5 mm. Ensure external noise from the system is not coupled into the oscilloscope probe.
The maximum IccMAX_1P8_CPU specification is preliminary and based on initial pre-silicon estimation and is subject to change.
Vcc1P8_PROC power rail may be named in different document as Vcc1P8_CPU
For S-process line, AC noise spec include VR self generated noise or input source AC noise that passes through to VR output and droop/overshoot due to transient load.
