AMD XC5VLX50-1FF676C

Overview

XC5VLX50-1FF676C from AMD (formerly Xilinx) is a Virtex-5 FPGA featuring 46,080 logic cells, 2.5 Gbps serial transceivers, and embedded Block RAM totaling 2,002 kbits. It implements high-speed signal processing in telecom line cards and supports PCIe Gen1 x8 endpoint functionality with integrated SelectIO technology for DDR2/DDR3 memory interfacing.

For engineers reviewing the XC5VLX50-1FF676C datasheet, pinout, applications, or equivalent options, key selection criteria include I/O count (480 user I/Os), transceiver lane count (12 lanes), static timing closure capability at -1 speed grade, and compatibility with Xilinx ISE Design Suite v14.7 for place-and-route.

Technical Context

The XC5VLX50-1FF676C uses a 65 nm copper process and employs a column-based architecture with dedicated DSP48E slices (64 total), clock management tiles (CMT) containing DCMs and PLLs, and multi-gigabit transceivers compliant with PCIe Base 1.1, SATA, and Serial RapidIO standards. It supports differential I/O standards including LVDS, RSDS, and BLVDS up to 1.25 Gbps.

Configuration occurs via Master SelectMAP or JTAG, with support for dual-boot from two external SPI flash devices. The device includes internal configuration monitoring and CRC checking, and operates across commercial temperature range (0°C to 85°C) with core voltage of 1.0 V ±3%.

FAQ

What is the maximum supported I/O standard voltage for XC5VLX50-1FF676C?

The XC5VLX50-1FF676C supports I/O voltages from 1.2 V to 3.3 V per bank, enabling concurrent use of SSTL18, HSTL, LVCMOS25, and LVDS standards. Each I/O bank has independent VCCO supply, allowing mixed-voltage operation across the device. This capability is confirmed in Xilinx UG192 (Virtex-5 Packaging and Pinout Specifications) and applies directly to the XC5VLX50-1FF676C in FF676 packaging.

Does XC5VLX50-1FF676C include built-in PCIe endpoint functionality?

Yes, the XC5VLX50-1FF676C integrates hard PCIe endpoint logic compliant with PCIe Base 1.1 specification, supporting x1, x2, x4, and x8 link widths. It includes AXI4-Lite register interface, transaction layer logic, and data link layer with error reporting. This feature is documented in Xilinx DS106 (Virtex-5 FPGA Data Sheet) and verified for the XC5VLX50-1FF676C variant.

What configuration modes are supported by XC5VLX50-1FF676C?

The XC5VLX50-1FF676C supports Master SelectMAP, Slave SelectMAP, JTAG, and Serial Peripheral Interface (SPI) configuration modes. Master SelectMAP is commonly used for high-speed parallel loading from external flash, while JTAG enables boundary-scan testing and in-system programming. All modes are defined in Xilinx UG191 (Virtex-5 Configuration User Guide) for this exact part number.

Is XC5VLX50-1FF676C qualified for automotive applications?

No, the XC5VLX50-1FF676C is rated for commercial temperature range (0°C to +85°C) and is not AEC-Q100 qualified. It lacks automotive-grade screening, extended temperature support, or fault-tolerant features required for automotive ECUs. For automotive use, designers should consider Xilinx Automotive (XA) variants such as XA5VLX50, which undergo additional qualification testing.

What tools are required to develop for XC5VLX50-1FF676C?

Development for XC5VLX50-1FF676C requires Xilinx ISE Design Suite version 14.7 or earlier, as later Vivado tools do not support Virtex-5 architecture. Synthesis, implementation, and bitstream generation must be performed using ISE; simulation is supported with ModelSim or ISIM. Device-specific constraints and timing analysis rely on ISE's PlanAhead toolset, validated for XC5VLX50-1FF676C in UG628.
