AMD XC5VSX95T-1FF1136I

Overview

XC5VSX95T-1FF1136I from AMD (formerly Xilinx) is a Virtex-5 FPGA featuring 94,208 logic cells, 128 DSP48E slices, 6.9 Mb of block RAM, and high-speed serial transceivers operating up to 3.75 Gb/s. It is packaged in a 1136-pin Flip-Chip Fine-Pitch Ball Grid Array (FFG1136) and targets high-bandwidth digital signal processing in radar and wired communications infrastructure.

For engineers reviewing the XC5VSX95T-1FF1136I datasheet, pinout, applications, or equivalent options, key selection criteria include transceiver lane count (12 lanes), I/O standard support (LVDS, SSTL, HSTL), embedded memory depth, and thermal performance under sustained 2.5 W dynamic power.

Technical Context

The XC5VSX95T-1FF1136I implements a hierarchical FPGA architecture with configurable logic blocks (CLBs), dedicated DSP48E slices for multiply-accumulate operations, and integrated RocketIO GTP transceivers. It supports multi-gigabit serial protocols including PCI Express Gen1, SATA, and Serial RapidIO.

Its SelectIO technology enables interface flexibility across 1.2 V to 3.3 V I/O standards, while the 6-input LUT-based logic fabric delivers deterministic timing closure for synchronous designs operating at up to 500 MHz system clock rates.

Key Specifications

Pinout & Package

XC5VSX95T-1FF1136I is housed in the FFG1136 package: a 1136-ball flip-chip BGA with thermal lid, designed for industrial temperature range (–40°C to +100°C junction). Pin assignment follows Xilinx UG192 (Virtex-5 Packaging and Pinout) with dedicated configuration, clock, JTAG, and transceiver banks.

FAQ

What is the maximum operating junction temperature for XC5VSX95T-1FF1136I?

The XC5VSX95T-1FF1136I is rated for industrial temperature operation with a maximum junction temperature of +100°C. This specification is validated under worst-case voltage, frequency, and ambient conditions defined in Xilinx DS100. Thermal management must maintain junction temperature within this limit using appropriate heatsinking and airflow, especially when operating multiple GTP transceivers at 3.75 Gb/s. The XC5VSX95T-1FF1136I integrates an on-die XADC for real-time monitoring of die temperature.

Does XC5VSX95T-1FF1136I support partial reconfiguration?

Yes, XC5VSX95T-1FF1136I supports partial reconfiguration through Xilinx ISE Design Suite 14.7 and later versions. This capability allows dynamic replacement of specific logic modules while the rest of the design remains operational. Use cases include protocol adaptation in communications gear or algorithm updates in radar processing. The XC5VSX95T-1FF1136I requires dedicated configuration logic and bitstream partitioning; full documentation is provided in UG194 (Virtex-5 Configuration User Guide).

What I/O standards are supported by XC5VSX95T-1FF1136I?

XC5VSX95T-1FF1136I supports LVDS, LVPECL, SSTL-18/2, HSTL-I/II, and differential signaling standards across its 640 user I/O pins. Each of the eight I/O banks operates independently and can be powered between 1.2 V and 3.3 V. The XC5VSX95T-1FF1136I does not support 1.0 V or sub-1.2 V I/O standards. Configuration and transceiver banks have fixed voltage requirements detailed in DS100.

Is XC5VSX95T-1FF1136I compatible with Vivado Design Suite?

No, XC5VSX95T-1FF1136I is not supported in Vivado Design Suite. It requires Xilinx ISE Design Suite 14.7 as the final and only officially supported toolchain. Vivado targets 7-series and newer architectures. Migration to newer devices like Kintex-7 or Virtex-7 is necessary to use Vivado. The XC5VSX95T-1FF1136I bitstream generation, timing analysis, and debugging workflows are fully validated only in ISE 14.7.

What is the configuration memory requirement for XC5VSX95T-1FF1136I?

The XC5VSX95T-1FF1136I requires a minimum 25.6 Mbit (3.2 MB) configuration PROM for master serial mode, as specified in DS100. This accounts for full bitstream size, CRC overhead, and startup clock cycles. Commonly used devices include XCF32P or third-party SPI flash with proper timing margins. The XC5VSX95T-1FF1136I supports fallback and multi-boot configurations when paired with larger PROMs, enabling field-upgradable firmware images.
