Product details
Overview
XC5VLX155T-1FF1136I from AMD (formerly Xilinx) is a Virtex-5 FPGA featuring 155,648 logic cells, 12.5 Mb of block RAM, and 640 DSP48E slices. It supports PCIe Gen1 x8, DDR2-533 memory interfaces, and operates at -1 speed grade with industrial temperature range (-40°C to +100°C). It is used in high-performance digital signal processing and reconfigurable computing systems.
For engineers reviewing the XC5VLX155T-1FF1136I datasheet, pinout, applications, or equivalent options, key selection criteria include I/O count (640 user I/Os), transceiver capability (no built-in multi-gigabit transceivers), and package thermal performance (FF1136 flip-chip BGA).
Technical Context
The XC5VLX155T-1FF1136I implements a column-based architecture with configurable logic blocks (CLBs), dedicated DSP slices, and hierarchical clock networks. It integrates SelectIO technology supporting LVDS, SSTL, HSTL, and differential signaling standards up to 1 Gb/s per pin.
This device belongs to the Virtex-5 LX family optimized for logic density and deterministic timing closure. It lacks integrated multi-gigabit transceivers-unlike the SX or FX variants-and targets applications requiring high gate count without serial transceiver functionality.

FAQ
What is the maximum supported memory interface speed for XC5VLX155T-1FF1136I?
The XC5VLX155T-1FF1136I supports DDR2-533 (266 MHz clock, 533 Mb/s data rate) using its SelectIO resources and dedicated memory controller logic. It does not support DDR3 or LPDDR interfaces. The device's I/O banks are configured per JEDEC SSTL18_I specifications to ensure signal integrity at these speeds, and timing closure requires careful PCB layout with matched trace lengths.
Does XC5VLX155T-1FF1136I include built-in PCI Express hard IP?
No, the XC5VLX155T-1FF1136I does not contain hard PCIe endpoint or root complex IP blocks. It supports PCIe Gen1 x8 via user-defined soft-core implementations using RocketIO transceivers - but this part lacks transceivers entirely. System-level PCIe connectivity must be implemented externally using companion PHY devices or discrete bridge chips interfaced through its 640-user I/Os.
What configuration modes are supported by XC5VLX155T-1FF1136I?
The XC5VLX155T-1FF1136I supports Master Serial, Slave Serial, Slave SelectMAP, and JTAG configuration modes, selected via M0–M2 pin strapping. Configuration bitstreams can be loaded from SPI flash, PROM, or host processor over SelectMAP or JTAG. Internal fallback mode enables automatic retry from secondary storage upon CRC failure during power-up.
Is XC5VLX155T-1FF1136I qualified for automotive applications?
No, the XC5VLX155T-1FF1136I is rated for industrial temperature range (-40°C to +100°C) and is not AEC-Q100 qualified. While it operates within extended temperature limits common in under-hood environments, it lacks automotive-specific reliability testing, failure-in-time (FIT) reporting, and PPAP documentation required for Tier 1 automotive deployments.
How many clock management tiles does XC5VLX155T-1FF1136I integrate?
The XC5VLX155T-1FF1136I integrates ten clock management resources: eight Digital Clock Managers (DCMs) and two Phase-Locked Loops (PLLs). These are distributed across the die to minimize clock skew and support independent domain synchronization. Each DCM provides fine-grained phase shifting and frequency synthesis, while the PLLs offer broader multiplication ranges and lower jitter for high-frequency clock domains.
