Product details
Overview
XC5VLX155T-1FFG1738I from AMD (formerly Xilinx) is a high-performance Virtex-5 FPGA featuring 155,648 logic cells, 12.5 Mb of block RAM, 640 DSP48E slices, and support for PCIe Gen1/Gen2, DDR2/DDR3 memory interfaces. It is used in high-speed data processing, radar signal conditioning, and reconfigurable computing systems.
For engineers reviewing the XC5VLX155T-1FFG1738I datasheet, pinout, applications, or equivalent options, key selection criteria include I/O count (720 user I/Os), speed grade (-1), thermal performance (industrial temperature range –40°C to +100°C), and FFG1738 flip-chip BGA package compatibility with high-density PCB routing.
Technical Context
The XC5VLX155T-1FFG1738I implements a column-based architecture with dedicated routing for clock, reset, and control signals. It integrates SelectIO technology supporting LVDS, SSTL, HSTL, and differential signaling standards up to 1.25 Gbps per I/O pair.
Its embedded PowerPC 440 hard processor cores are not present in this LX family variant; instead, it delivers deterministic timing via hierarchical clock networks with 32 global clock buffers and 16 regional clock buffers, enabling sub-nanosecond skew across large designs.

FAQ
What is the maximum supported memory interface speed for XC5VLX155T-1FFG1738I?
The XC5VLX155T-1FFG1738I supports DDR2-800 and DDR3-1066 memory interfaces using its hardened memory controller logic. This enables sustained data rates up to 1066 MT/s with full calibration support including write leveling and read leveling, as specified in Xilinx UG190 and DS106 documentation for the Virtex-5 LX family.
Does XC5VLX155T-1FFG1738I include built-in transceivers for high-speed serial communication?
No, the XC5VLX155T-1FFG1738I belongs to the LX (Logic eXtended) subfamily and does not integrate multi-gigabit transceivers. High-speed serial connectivity must be implemented externally or via parallel I/O interfaces such as LVDS or SelectIO-based protocols. Transceiver capability is available only in Virtex-5 FX (embedded PowerPC + RocketIO) and SX (DSP-optimized) variants.
What configuration modes are supported by XC5VLX155T-1FFG1738I?
The XC5VLX155T-1FFG1738I supports Master SelectMAP, Slave SelectMAP, Serial, and JTAG configuration modes. Configuration bitstreams can be loaded from external SPI flash, PROM, or host processor via parallel or serial interfaces, with fallback support enabled through dual-PROM schemes per Xilinx UG191.
Is XC5VLX155T-1FFG1738I qualified for automotive applications?
No, XC5VLX155T-1FFG1738I is rated for industrial temperature range (–40°C to +100°C) and is not AEC-Q100 qualified. It lacks automotive-specific screening, failure rate reporting, and extended reliability testing required for under-hood or safety-critical vehicle systems.
Can XC5VLX155T-1FFG1738I implement partial reconfiguration in the field?
Yes, XC5VLX155T-1FFG1738I supports hardware-accelerated partial reconfiguration using Xilinx PlanAhead and Vivado tools. This allows dynamic swapping of functional modules without resetting the entire device, enabling runtime adaptation in radar waveform generation or protocol translation applications.
