FAQ

What is the maximum data rate supported by the RocketIO transceivers in XC4VFX12-10FF668I?

The XC4VFX12-10FF668I features four RocketIO transceivers each capable of 3.75 Gbps operation. This enables full-duplex serial links compliant with PCI Express 1.0, Serial RapidIO 1.x, and Gigabit Ethernet. The transceivers include built-in clock data recovery, elastic buffers, and 8B/10B encoding/decoding logic. XC4VFX12-10FF668I does not support rates above 3.75 Gbps per lane.

Does XC4VFX12-10FF668I include embedded processor cores?

Yes, XC4VFX12-10FF668I integrates two hard-core PowerPC 405 RISC processors running at up to 400 MHz. Each core includes 32 KB instruction and 32 KB data cache, MMU, and debug interface. XC4VFX12-10FF668I supports symmetric multiprocessing and shared memory access via the internal PLB bus. No external microprocessor is needed for control-plane tasks.

What I/O voltage standards are supported by XC4VFX12-10FF668I?

XC4VFX12-10FF668I supports LVCMOS, LVTTL, SSTL-2, SSTL-3, HSTL-I, HSTL-II, and LVDS across its 444 user I/O pins. Each of the 16 I/O banks can be independently configured for 1.2 V, 1.5 V, 1.8 V, 2.5 V, or 3.3 V VCCO. XC4VFX12-10FF668I does not support 1.0 V or sub-1.2 V I/O standards.

Is XC4VFX12-10FF668I suitable for aerospace applications?

XC4VFX12-10FF668I is rated for industrial temperature range (–40°C to +100°C) and has been used in DO-254-compliant avionics systems. It supports configuration security, CRC-based bitstream integrity checking, and SEU mitigation via EDAC on block RAM. XC4VFX12-10FF668I is not radiation-hardened or QML-V qualified, so system-level qualification is required for flight-critical use.

What configuration modes does XC4VFX12-10FF668I support?

XC4VFX12-10FF668I supports master SPI, slave serial, slave parallel (SelectMAP), and JTAG boundary-scan configuration. Configuration is initiated via mode pins M0–M2 and controlled by CCLK. Bitstream loading can occur from external SPI flash, microcontroller, or JTAG debugger. XC4VFX12-10FF668I does not support passive parallel or BPI configuration modes.
