FAQ

What is the maximum operating frequency of the XC5VLX155-1FF1153I?

The XC5VLX155-1FF1153I has a -1 speed grade, meaning its guaranteed maximum operating frequency for internal logic is 512 MHz for register-to-register paths under industrial temperature conditions. This value is validated in Xilinx UG192 and applies to fully routed and timing-closed designs meeting setup/hold constraints.

Does the XC5VLX155-1FF1153I support partial reconfiguration?

Yes, the XC5VLX155-1FF1153I supports partial reconfiguration through its native bitstream architecture and associated tools in Vivado Design Suite. This capability allows dynamic replacement of logic modules without resetting the entire device-enabling adaptive functions such as protocol switching or algorithm updates in deployed systems.

What configuration modes does the XC5VLX155-1FF1153I support?

The XC5VLX155-1FF1153I supports multiple configuration modes including Master Serial (via SPI flash), Slave SelectMAP (parallel bus from microprocessor), JTAG boundary-scan, and System ACE. Mode selection is controlled by M0–M2 pins at power-up, and all modes are documented in Xilinx UG191.

Is the XC5VLX155-1FF1153I RoHS compliant?

Yes, the XC5VLX155-1FF1153I is RoHS-6 compliant and lead-free, with exemption 7a (lead in high melting temperature type solders) applicable to certain internal interconnect layers. Full compliance documentation is available in AMD's Product Change Notification PCN-2018-001.

What thermal management guidance applies to the XC5VLX155-1FF1153I?

The XC5VLX155-1FF1153I requires a thermal solution capable of dissipating up to 12.5 W under worst-case operating conditions. AMD recommends a 4-layer PCB with internal ground/power planes, thermal vias under the package, and a heatsink rated for ≥15°C/W junction-to-ambient resistance to maintain junction temperature below 100°C.
