Product details
Overview
XC4VFX20-10FF672C from AMD (formerly Xilinx) is a Virtex-4 FX family FPGA featuring 20,800 logic cells, embedded PowerPC 405 RISC processors, and integrated multi-gigabit transceivers operating up to 3.125 Gbps. It uses a 672-pin Fine-Pitch Flip-Chip BGA (FF672) package with 1.2 V core voltage and supports PCI Express x1 endpoint functionality in high-speed communications systems.
For engineers reviewing the XC4VFX20-10FF672C datasheet, pinout, applications, or equivalent options, key selection considerations include transceiver lane count, embedded processor availability, I/O bank voltage flexibility, and PCIe compliance for reconfigurable computing platforms.
Technical Context
The XC4VFX20-10FF672C integrates two hardened PowerPC 405 cores with on-chip memory controllers and dual 10/100/1000 Ethernet MACs. Its 16 multi-gigabit transceivers support protocols including Serial RapidIO, Aurora, and PCI Express Gen1.
It implements SelectIO technology with support for LVDS, SSTL, HSTL, and differential signaling across 444 user I/Os distributed across 12 I/O banks, each configurable for 1.2 V, 1.5 V, 1.8 V, 2.5 V, or 3.3 V operation.

FAQ
What is the maximum supported transceiver data rate for XC4VFX20-10FF672C?
The XC4VFX20-10FF672C supports a maximum transceiver data rate of 3.125 Gbps per lane. This rate is validated for protocols including PCI Express Gen1, Serial RapidIO, and Aurora. The transceivers are not rated for 6.25 Gbps operation, and exceeding 3.125 Gbps may result in link instability or failure to meet jitter specifications defined in the XC4VFX20-10FF672C datasheet.
Does XC4VFX20-10FF672C include built-in Ethernet MAC functionality?
Yes, XC4VFX20-10FF672C integrates two hard 10/100/1000 Ethernet MACs compliant with IEEE 802.3. These MACs connect directly to external PHY devices via GMII or RGMII interfaces and operate independently of the PowerPC cores. The MACs are part of the fixed-function logic block and require no LUT resources, making them available for use in any XC4VFX20-10FF672C design without consuming programmable logic.
What configuration modes does XC4VFX20-10FF672C support?
XC4VFX20-10FF672C supports Master Serial, Slave Serial, Master SelectMAP, Slave SelectMAP, and JTAG configuration modes. Configuration bitstream loading can be initiated via dedicated pins (CCLK, DIN, INIT_B, PROGRAM_B) or through boundary-scan using the IEEE 1149.1 TAP controller. The XC4VFX20-10FF672C does not support passive parallel configuration without external controller logic.
Is XC4VFX20-10FF672C qualified for automotive applications?
No, XC4VFX20-10FF672C is not AEC-Q100 qualified and is not recommended for automotive safety-critical systems. It is specified for commercial and industrial temperature ranges (0°C to 85°C for C-grade). For automotive use, Xilinx offered separate Automotive (Q-grade) Virtex-4 variants with extended temperature range and qualification testing - XC4VFX20-10FF672C is not one of them.
Can XC4VFX20-10FF672C operate with a single 1.2 V supply?
No, XC4VFX20-10FF672C requires three distinct supply voltages: 1.2 V for core (VCCINT), 2.5 V for auxiliary circuits (VCCAUX), and programmable I/O bank voltages (VCCO) ranging from 1.2 V to 3.3 V. Using only a 1.2 V rail will prevent configuration and cause functional failure. All three supply domains must be properly sequenced during power-up per the XC4VFX20-10FF672C power management guidelines.
