Product details
Overview
XC5VSX35T-1FF665I from AMD (formerly Xilinx) is a Virtex-5 FPGA featuring 34,656 logic cells, 2.5 Gbps serial transceivers, and embedded Block RAM. It implements high-speed signal processing in radar baseband units and supports PCIe Gen1 endpoint functionality with integrated RocketIO transceivers.
For engineers reviewing the XC5VSX35T-1FF665I datasheet, pinout, applications, or equivalent options, key selection criteria include transceiver data rate, I/O bank voltage support, configuration interface type, and thermal performance under sustained DSP load.
Technical Context
The XC5VSX35T-1FF665I belongs to the Virtex-5 SX family optimized for serial connectivity and DSP-intensive tasks. It integrates 12 RocketIO GTP transceivers (2.5 Gbps), 180 DSP48E slices, and supports SelectIO standards including LVDS, SSTL, and HSTL across 16 I/O banks.
Configuration is performed via Master Serial mode using external SPI flash or JTAG. The device uses 65 nm copper CMOS process and requires dual-supply operation: 1.0 V core, 2.5 V auxiliary, and 3.3 V I/O.

FAQ
What is the operating temperature range for XC5VSX35T-1FF665I?
The XC5VSX35T-1FF665I is rated for industrial temperature operation from –40°C to +100°C junction temperature. This range supports deployment in harsh environments such as avionics enclosures and outdoor radar cabinets. Thermal design must maintain case temperature below 90°C under full transceiver and DSP utilization. The XC5VSX35T-1FF665I datasheet specifies derating curves for ambient temperature versus power dissipation.
Does XC5VSX35T-1FF665I support PCIe Gen2?
No, the XC5VSX35T-1FF665I supports PCIe Gen1 only, with RocketIO GTP transceivers rated up to 2.5 Gbps. It does not meet the 5.0 Gbps requirement for PCIe Gen2. For Gen2 compatibility, designers must migrate to Virtex-6 or later families. The XC5VSX35T-1FF665I configuration and timing constraints are validated exclusively for Gen1 link training and enumeration.
What configuration modes does XC5VSX35T-1FF665I support?
The XC5VSX35T-1FF665I supports Master Serial (SPI flash), Slave Serial, JTAG, and Boundary Scan modes. Mode selection is controlled by M0–M2 pins at power-up. Master Serial is most common for production boot; JTAG is used for debugging and in-system programming. The XC5VSX35T-1FF665I does not support BPI or SelectMAP modes in this speed grade and package variant.
Can XC5VSX35T-1FF665I operate with 1.8 V I/O voltage?
Yes, XC5VSX35T-1FF665I supports 1.8 V I/O through dedicated I/O banks configured for SSTL18 or HSTL_I standards. Each of the 16 I/O banks can be independently set to 1.2 V, 1.5 V, 1.8 V, 2.5 V, or 3.3 V. Proper VCCO assignment and termination resistor placement are required per bank. The XC5VSX35T-1FF665I pinout documentation specifies which balls belong to each configurable bank.
Is XC5VSX35T-1FF665I still in active production?
XC5VSX35T-1FF665I is in long-term availability status per AMD's Virtex-5 product discontinuation notice. Last time buy (LTB) was announced in Q3 2021, with final shipments completed in Q2 2023. Aetrix Electronics maintains legacy inventory with full traceability and offers lifecycle management support for ongoing production programs using the XC5VSX35T-1FF665I.
