3.3. Power-Down Sequence Requirements for Intel® Agilex™ Devices with E-Tile

Intel® Agilex™ devices with E-tile must follow certain requirements during a power-down sequence. The power-down sequence can be a controlled power-down event via an on or off switch or an uncontrolled event such as a power supply collapse. In either situation, you must follow a specific power-down sequence.

  • Power down all power rails fully within 100 ms.
  • Before Group 1 (VCC_HSSI_GXE) supply power down, power down Group 2 (VCCH_GXE & VCCCLK_GXE) supplies within 10% of the nominal voltage.

For Intel® Agilex™ devices with E-tile, you can combine and ramp down other voltage rails that share the same voltage level and the same voltage regulator.
