FAQ

What is the maximum data rate supported by the RocketIO transceivers in XC4VFX12-11FFG668I?

The XC4VFX12-11FFG668I features four RocketIO transceivers each capable of 3.125 Gbps line rate. These transceivers support protocols including PCI Express Gen1, Serial RapidIO, and Gigabit Ethernet. The 3.125 Gbps rate is specified under recommended operating conditions and includes built-in encoding (8B/10B) and clock recovery circuitry. Actual usable throughput depends on protocol overhead and link training success.

Does XC4VFX12-11FFG668I include embedded processors, and how many?

Yes, the XC4VFX12-11FFG668I integrates two hard-core PowerPC 405 RISC processors. Each core includes 32 KB instruction cache and 32 KB data cache, and both share access to on-chip PLB and OPB buses. These processors are fully functional upon configuration and support boot-from-PROM, JTAG debug, and real-time interrupt handling-making XC4VFX12-11FFG668I suitable for tightly coupled software-hardware systems.

What I/O voltage standards does XC4VFX12-11FFG668I support?

The XC4VFX12-11FFG668I supports multiple I/O standards across its 12 configurable I/O banks, including LVCMOS (1.2 V, 1.5 V, 1.8 V, 2.5 V, 3.3 V), LVTTL, SSTL-2, SSTL-3, HSTL-I, HSTL-II, and differential standards such as LVDS, BLVDS, and RSDS. Each bank's VCCO and VRN/VRP voltages must be set according to selected standard, and mixing standards within a bank is prohibited per Xilinx DS112 specification.

Is XC4VFX12-11FFG668I suitable for extended temperature applications?

Yes, the XC4VFX12-11FFG668I is rated for industrial temperature operation from -40°C to +100°C. This rating applies to the FFG668 package variant and is verified per Xilinx qualification standards. Thermal design must account for power dissipation up to 7.2 W typical under full utilization, and PCB layout should follow Xilinx UG070 guidelines for thermal vias and copper pour under the thermal lid.

Can XC4VFX12-11FFG668I be partially reconfigured in-system?

Yes, the XC4VFX12-11FFG668I supports partial reconfiguration through its ICAP (Internal Configuration Access Port) interface. This allows designated logic regions to be updated dynamically while the rest of the design remains operational. Implementation requires use of Xilinx ISE 10.1 or later tools, proper floorplanning with Pblock constraints, and careful handling of inter-region signal routing-enabling adaptive functionality in XC4VFX12-11FFG668I-based systems without full device reset.
