AMD XC5VSX35T-2FFG665I

Overview

XC5VSX35T-2FFG665I from AMD (formerly Xilinx) is a Virtex-5 FPGA featuring 34,656 logic cells, 2.5 Gbps serial transceivers, and embedded Block RAM totaling 2,002 kbits. It implements high-speed signal processing in radar baseband subsystems and supports PCIe Gen1 x4 endpoint functionality with integrated RocketIO GTP transceivers.

For engineers reviewing the XC5VSX35T-2FFG665I datasheet, pinout, applications, or equivalent options, key selection criteria include transceiver compliance (PCIe Gen1), I/O voltage support (1.2 V, 1.5 V, 1.8 V, 2.5 V, 3.3 V), static timing closure at -2 speed grade, and thermal management for industrial temperature operation.

Technical Context

The XC5VSX35T-2FFG665I integrates 24 RocketIO GTP transceivers operating up to 2.5 Gbps, each supporting protocols including PCIe Gen1 and SATA. Its SelectIO interface supports differential standards (LVDS, RSDS, BLVDS) and single-ended standards (LVTTL, LVCMOS) across 480 user I/O pins.

This device belongs to the Virtex-5 SX family optimized for serial connectivity and DSP-intensive tasks. It uses 65 nm copper process technology, includes 18 × 18 multipliers, and delivers 195 GMACs of DSP performance with dedicated SRL16/SRL32 shift registers and wide multiplexers per CLB.

Key Specifications

Pinout & Package

XC5VSX35T-2FFG665I is housed in a 665-pin Flip-Chip Fine-Pitch Ball Grid Array (FFG) package with 35 mm × 35 mm body size, 1.0 mm ball pitch, and Pb-free / RoHS-compliant construction. Thermal pad on underside requires solder paste stencil design per Xilinx UG192.

The Virtex-5 SX family was architected specifically for applications demanding high-speed serial connectivity and embedded DSP, such as radar signal processing, optical transport line cards, and real-time video analytics engines.

FAQ

What is the maximum supported data rate per GTP transceiver in XC5VSX35T-2FFG665I?

The XC5VSX35T-2FFG665I supports up to 2.5 Gbps per GTP transceiver channel. This rate is validated for PCIe Gen1 and SATA 1.5 Gbps operation with built-in 8B/10B encoding. The transceivers do not support rates above 2.5 Gbps, and operation at 2.5 Gbps requires proper PCB impedance control and termination per Xilinx UG191.

Does XC5VSX35T-2FFG665I support partial reconfiguration?

Yes, the XC5VSX35T-2FFG665I supports partial reconfiguration through its FPGA fabric and configuration logic. This capability allows dynamic module swapping during runtime-critical for adaptive SDR waveforms and radar mode switching. Implementation requires Xilinx ISE 14.7 or later and adherence to area-group constraints defined in UG192.

What I/O standards are supported by XC5VSX35T-2FFG665I in bank 0?

XC5VSX35T-2FFG665I bank 0 supports LVCMOS, LVTTL, SSTL, HSTL, and differential standards including LVDS and RSDS, provided VCCO is set to the appropriate voltage (1.2 V to 3.3 V). Each bank's I/O standard is independently configurable, and mixing standards within a bank is prohibited per Xilinx DC and Switching Characteristics documentation.

Is XC5VSX35T-2FFG665I qualified for automotive applications?

No, XC5VSX35T-2FFG665I is specified for industrial temperature range (–40°C to +100°C) and is not AEC-Q100 qualified. It lacks automotive-specific screening, failure-in-time (FIT) reporting, and qualification test data required for automotive ECUs. For automotive use, AMD recommends evaluating the XA-Virtex-5 family instead.

What configuration modes does XC5VSX35T-2FFG665I support?

The XC5VSX35T-2FFG665I supports Master SelectMAP, Slave SelectMAP, Serial, and JTAG configuration modes. Master SelectMAP is commonly used for fast parallel loading from external flash; JTAG is reserved for debugging and programming during development. Configuration mode is selected via MODE pins per Table 1-2 in DS106.
