AMD XC5VLX155T-3FF1136C

Overview

XC5VLX155T-3FF1136C from AMD (formerly Xilinx) is a Virtex-5 FPGA featuring 155,328 logic cells, 12.5 Mb of block RAM, and 640 DSP48E slices. It supports PCIe Gen1 x8, DDR2-533 memory interfaces, and operates at -3 speed grade with 1.0V core voltage. Used in high-performance digital signal processing and reconfigurable computing systems.

For engineers reviewing the XC5VLX155T-3FF1136C datasheet, pinout, applications, or equivalent options, key selection factors include I/O count (640 user I/Os), transceiver capability (no built-in multi-gigabit transceivers), thermal design power (21.5 W typical), and FF1136 package compatibility.

Technical Context

The XC5VLX155T-3FF1136C implements a column-based architecture with configurable logic blocks (CLBs), dedicated DSP slices, and integrated memory controllers. It supports SelectIO standards including LVCMOS, LVDS, and SSTL, and includes clock management tiles with DCM and PLL for jitter reduction and frequency synthesis.

This device belongs to the Virtex-5 LX family optimized for logic density and deterministic timing closure. It lacks RocketIO GTP transceivers - distinguishing it from SX and FX variants - and targets applications requiring high gate count without serial transceiver integration.

Key Specifications

Pinout & Package

XC5VLX155T-3FF1136C is housed in a 1136-pin Flip-Chip Fine-Pitch Ball Grid Array (FF1136) package with 35×35 mm body size, 1.0 mm ball pitch, and Pb-free/CuNiAu finish. Thermal pad on underside requires solder paste stencil design per Xilinx UG192.

FAQ

What is the maximum operating frequency supported by XC5VLX155T-3FF1136C?

The XC5VLX155T-3FF1136C is rated at speed grade -3, guaranteeing timing closure for system clocks up to 500 MHz in critical paths. Actual achievable frequency depends on design complexity, routing congestion, and I/O standard selection - verified via Xilinx ISE timing analysis using the -3 speed file.

Does XC5VLX155T-3FF1136C include built-in transceivers for high-speed serial communication?

No, XC5VLX155T-3FF1136C does not integrate multi-gigabit transceivers. It belongs to the LX (Logic-optimized) subfamily of Virtex-5, which omits RocketIO GTP blocks. High-speed serial links must be implemented externally or via parallel interfaces like PCIe Gen1 x8 using dedicated endpoint logic.

What configuration modes are supported by XC5VLX155T-3FF1136C?

XC5VLX155T-3FF1136C supports Master Serial (SPI flash), Slave Serial, Boundary Scan (JTAG), and SelectMAP modes. Configuration mode is selected by M0–M2 pin states at power-on reset, and all modes comply with Xilinx UG191 specification for Virtex-5 configuration.

Can XC5VLX155T-3FF1136C interface directly with DDR2-800 memory?

No, XC5VLX155T-3FF1136C's integrated memory controller supports DDR2-533 (266 MHz clock, 533 Mbps data rate) as specified in DS100. Driving DDR2-800 would violate timing margins and is not validated - external memory controller or FPGA-based soft controller would be required.

Is XC5VLX155T-3FF1136C RoHS compliant and lead-free?

Yes, XC5VLX155T-3FF1136C uses a Pb-free/CuNiAu surface finish on its FF1136 package and complies with RoHS Directive 2011/65/EU. The device is marked with the RoHS symbol and meets JEDEC J-STD-609A Class 3 moisture sensitivity level (MSL3).
