It is used in high-performance digital signal processing and reconfigurable computing systems requiring deterministic timing and multi-gigabit serial I/O.

For engineers reviewing the XC5VLX85T-1FF1136I datasheet, pinout, applications, or equivalent options, key selection considerations include I/O bank voltage support (1.2 V to 3.3 V), GTX transceiver count (24 lanes), and thermal design power (17.5 W typical at full utilization).

Technical Context

The XC5VLX85T-1FF1136I implements a hierarchical FPGA architecture with six distinct logic tile types, including Configurable Logic Blocks (CLBs), dedicated DSP48E blocks for multiply-accumulate operations, and integrated PCI Express® Endpoint blocks. It supports DDR2 SDRAM interfaces up to 533 MHz and includes 24 GTX serial transceivers operating from 100 Mbps to 6.5 Gbps.

This device belongs to the Virtex-5 LX family and uses 65 nm copper process technology with triple-oxide transistor design. It supports SelectIO™ standards including LVCMOS, SSTL, HSTL, and differential standards such as LVDS and TMDS, with programmable slew rate and drive strength per I/O.

Key Specifications

Pinout & Package

FAQ

What is the maximum supported data rate for GTX transceivers on the XC5VLX85T-1FF1136I?

The XC5VLX85T-1FF1136I GTX transceivers support a maximum data rate of 6.5 Gbps per lane. This is confirmed in the Virtex-5 FPGA GTX Transceiver User Guide (UG196 v3.5), which specifies operational range from 100 Mbps to 6.5 Gbps with built-in clock correction and 8B/10B encoding. The XC5VLX85T-1FF1136I achieves this rate under -1 speed grade conditions with proper reference clock stability and PCB interconnect design.

Does the XC5VLX85T-1FF1136I support DDR3 memory interfaces?

The XC5VLX85T-1FF1136I does not include native DDR3 controller hard IP. It supports DDR2 SDRAM up to 533 MHz using the MIG v3.7 controller core. DDR3 operation requires external PHY or soft logic implementation, which is not validated or characterized by AMD for the XC5VLX85T-1FF1136I. Designers should use the XC5VLX85T-1FF1136I only for DDR2-based systems unless third-party IP with full timing closure is employed.

What configuration modes are supported by the XC5VLX85T-1FF1136I?

The XC5VLX85T-1FF1136I supports Master SelectMAP, Slave SelectMAP, JTAG, and Serial configuration modes. Configuration is initiated via mode pins (M[2:0]) at power-up. The XC5VLX85T-1FF1136I requires an external PROM or processor to load bitstream in Master modes, while JTAG enables boundary-scan testing and partial reconfiguration. All modes are documented in the Virtex-5 Configuration User Guide (UG191 v4.1).

Is the XC5VLX85T-1FF1136I RoHS compliant?

Yes, the XC5VLX85T-1FF1136I is RoHS compliant and Pb-free. Its FFG1136 package uses lead-free solder balls and meets EU Directive 2011/65/EU requirements. The device is marked with the RoHS symbol on the top surface and listed in AMD's official compliance database under document DS878 (Virtex-5 Packaging and Reliability Report). The XC5VLX85T-1FF1136I also complies with JEDEC J-STD-020 moisture sensitivity level 3.

What is the recommended operating junction temperature range for the XC5VLX85T-1FF1136I?

The XC5VLX85T-1FF1136I is rated for industrial temperature operation from –40°C to +100°C junction temperature. This range is specified in the Virtex-5 DC and Switching Characteristics Data Sheet (DS106 v4.4). Thermal design must ensure the die temperature remains within this limit under worst-case voltage, frequency, and ambient conditions. The XC5VLX85T-1FF1136I includes on-die temperature sensors accessible via XADC for real-time monitoring.
