AMD XC5VLX155T-2FF1738I

Overview

XC5VLX155T-2FF1738I from AMD (formerly Xilinx) is a high-performance Virtex-5 FPGA featuring 155,328 logic cells, 12.8 Gb/s serial transceiver bandwidth, and -2 speed grade in a 1738-pin Flip-Chip Fine-Pitch BGA package. It serves as a reconfigurable system-on-chip for high-speed protocol bridging in telecom line cards.

For engineers reviewing the XC5VLX155T-2FF1738I datasheet, pinout, applications, or equivalent options, key selection criteria include transceiver compliance with PCIe Gen1/2, embedded PowerPC 440 cores, and support for DDR2/DDR3 memory interfaces.

Technical Context

The XC5VLX155T-2FF1738I implements a hierarchical FPGA architecture with six distinct logic tile types, including DSP48E slices delivering 550 GMAC/s peak performance and Block RAM with true dual-port 36 Kb configuration. Its RocketIO GTP transceivers operate at 1.25–3.75 Gb/s with built-in 8B/10B encoding and elastic buffers.

Configuration is supported via Master SelectMAP, Slave SelectMAP, or JTAG, with bitstream encryption using AES-256 and HMAC-SHA-256 authentication. The device integrates two PowerPC 440 hard processor cores running at up to 550 MHz, each with 32 KB instruction and 32 KB data L1 cache.
