The following table shows the revision history for this document.
| Section | Revision Summary |
|---|---|
| 05/03/2024 Version 1.1 | |
| Introduction | Added reference to Defense-Grade UltraScale Architecture Data Sheet: Overview (DS895) for available XQ UltraScale+ devices and ruggedized packages. |
| UltraScale+ Device SEL | |
| SEL Impact, Power Guidelines, Decoupling Capacitors | Added Zynq UltraScale+ RFSoC XQZU48DR, XQZU49DR, XQZU65DR, and XQZU67DR devices throughout. |
| LVAUX Mode Overview, Special Considerations for XQ Ruggedized FPGAs | Added clarification that XQ Virtex UltraScale+ devices do not have HD I/O pins and their packages use the VCCAUX_IO name for pins that supply the auxiliary power to the HP I/O. Whereas, XQ Kintex UltraScale+ and Zynq UltraScale+ ruggedized packages use the VCCAUX_HPIO pin name for pins that supply the auxiliary power only to the HP I/O. |
| SelectIO Resources, Summary of LVAUX Mode versus Standard Operating Mode, LVAUX Mode Checklists, I/O Guidelines, Rules for Combining I/O Standards in the Same Bank | Added notes throughout that system monitor external analog inputs are not supported in LVAUX mode HP I/O banks. |
| DC I/O Levels, IOB High Performance Switching Characteristics, LVDS12_LVAUX | Added clarifications that LVDS12_LVAUX is compatible with some LVDS standards. |
| PCB Design Guidelines | Revised decoupling capacitor recommendations to maintain alignment to revision in Decoupling for Defense Grade XQ Devices in UltraScale Architecture PCB Design User Guide (UG583). The capacitor values and part numbers have been updated taking into account the latest product offerings from various vendors because some of the part numbers from the previous versions of this user guide have reached end of life. The new guidelines also incorporate capacitors with a wider temperature range (X7R) compared to the previous part numbers. The prior capacitor tables and specifications are still valid for existing designs, but for new designs, the current tables and specifications are recommended. |
