Notes: 1.Connect VCCINT and VCCINT_IO together for -3, -2, and -1 speed grades. The capacitors listed are the total number of capacitors for the combined rail. 2.Connect VCCBRAM and VCCINT_IO together for -2L and -1L speed grades. The capacitors listed are the total number of capacitors for the combined rail. 3.VCCAUX and VCCAUX_IO must share the same plane on the PCB. The capacitors listed are the total number of capacitors for the combined rail. 4.The 47 µF capacitor can be combined at one per every four HPIO banks. 5.The XCVU19P devices have land-side capacitors (LSCs) on the bottom side of the packages, which leads to fewer 10 µF capacitors required on the PCB compared to other similar sized devices. 6.This is for boards approximately ³ 200 mil thickness. 7.The XCVU19P devices are recommended to be edge bonded. Refer to the Thermal Specifications chapter of UltraScale and UltraScale+ FPGAs Packaging and Pinouts Product Specification (UG575) [Ref 9] for edge bonding guidelines. |
