Product details
Overview
XC5VLX85-1FFG676CES from AMD (formerly Xilinx) is a Virtex-5 FPGA featuring 85,200 logic cells, 4.8 Mb of block RAM, and 240 DSP48E slices. It supports PCIe Gen1 x8, DDR2-533 memory interfaces, and operates at -1 speed grade with 1.0V core voltage. Used in high-performance digital signal processing and reconfigurable computing systems.
For engineers reviewing the XC5VLX85-1FFG676CES datasheet, pinout, applications, or equivalent options, key selection factors include I/O count (480 user I/Os), transceiver capability (no integrated multi-gigabit transceivers), thermal design power (12.5 W typical), and package compatibility with FFG676 footprint.
Technical Context
The XC5VLX85-1FFG676CES implements a column-based architecture with configurable logic blocks (CLBs), dedicated DSP slices, and hierarchical clock networks. It supports SelectIO standards including LVCMOS, LVDS, and SSTL, with programmable input delay and output slew rate control.
Configuration is performed via Master Serial or JTAG mode using external PROM or processor-controlled interface. The device lacks built-in configuration memory and requires external configuration storage for persistent operation after power cycle.

FAQ
What is the maximum supported DDR2 memory interface speed for XC5VLX85-1FFG676CES?
The XC5VLX85-1FFG676CES supports DDR2-533 operation (266 MHz clock, 533 Mbps data rate) using its dedicated memory controller hard IP and calibrated I/O timing. This capability is validated in Xilinx UG190 and requires proper PCB layout with matched trace lengths and controlled impedance. The XC5VLX85-1FFG676CES does not support DDR3 or LPDDR2 interfaces.
Does XC5VLX85-1FFG676CES include integrated multi-gigabit transceivers?
No, the XC5VLX85-1FFG676CES does not contain integrated multi-gigabit transceivers. It belongs to the LX (Logic eXtended) subfamily of Virtex-5 FPGAs, which focuses on logic density and I/O flexibility rather than high-speed serial connectivity. Designs requiring PCIe Gen2, SATA, or Serial RapidIO must use external PHYs or select a Virtex-5 FX or SX variant. The XC5VLX85-1FFG676CES relies on parallel I/O standards like LVDS and RSDS for high-speed data transfer.
What configuration modes are supported by XC5VLX85-1FFG676CES?
The XC5VLX85-1FFG676CES supports Master Serial, Slave Serial, Slave SelectMAP, and JTAG configuration modes. Master Serial is most common for standalone operation using external SPI PROM. JTAG is used for debugging and in-system programming. All modes require external configuration memory - the XC5VLX85-1FFG676CES has no on-chip nonvolatile configuration storage.
Is XC5VLX85-1FFG676CES RoHS compliant and lead-free?
Yes, the XC5VLX85-1FFG676CES is RoHS-compliant and features a lead-free (Pb-free) finish on its solder balls. The "ES" suffix denotes an engineering sample with identical packaging and compliance to production-grade specifications. Full qualification data is documented in Xilinx PDN-XA-0012 and AMD's current material declarations.
What is the thermal design power (TDP) of XC5VLX85-1FFG676CES under typical operating conditions?
The XC5VLX85-1FFG676CES has a typical thermal design power of 12.5 W at 80°C junction temperature, 1.0 V core voltage, and 50% logic utilization. Power estimation requires Xilinx XPE tool with accurate toggle rate inputs. The XC5VLX85-1FFG676CES thermal pad is exposed on the underside and must be soldered to a thermal plane for reliable operation above 8 W sustained dissipation.
