AMD XC5VLX50-2FF676I

Overview

XC5VLX50-2FF676I from AMD (formerly Xilinx) is a Virtex-5 FPGA featuring 46,080 logic cells, 2.5 Gb/s serial transceivers, and embedded Block RAM totaling 2,880 kbits. It implements high-speed signal processing in radar baseband systems and supports PCI Express Gen1 endpoint functionality with integrated RocketIO GTP transceivers.

For engineers reviewing the XC5VLX50-2FF676I datasheet, pinout, applications, or equivalent options, key selection criteria include I/O voltage support (1.2 V to 3.3 V), -2 speed grade timing performance, and FF676 flip-chip BGA package compatibility with thermal and routing constraints.

Technical Context

The XC5VLX50-2FF676I uses a 65 nm copper process and employs a hierarchical CLB architecture with four-input LUTs and dual-register flip-flops. It integrates 12 RocketIO GTP transceivers supporting 100 Mbps–2.5 Gbps line rates and includes dedicated DSP48E slices for arithmetic-intensive tasks.

Configuration occurs via Master SelectMAP or JTAG, with support for multi-boot from external SPI flash. The device implements partial reconfiguration capability and features on-chip termination control for differential I/O standards including LVDS and RSDS.

Key Specifications

Pinout & Package

XC5VLX50-2FF676I is housed in a 27×27 mm, 676-pin flip-chip BGA (FF676) package with 16 I/O banks, each supporting independent VCCO and VREF. Pin functions are bank- and row-dependent; configuration pins (e.g., INIT_B, PROGRAM_B, DONE) are fixed, while user I/O are fully assignable within bank constraints.

FAQ

What is the maximum supported I/O standard voltage for XC5VLX50-2FF676I?

The XC5VLX50-2FF676I supports I/O voltages from 1.2 V to 3.3 V across its 16 banks, with bank-specific VCCO and VREF settings. Each bank can be independently configured for LVCMOS, LVTTL, LVDS, or RSDS, enabling mixed-voltage board designs without level shifters. This flexibility allows direct interfacing with legacy and modern peripherals in the same system.

Does XC5VLX50-2FF676I support partial reconfiguration?

Yes, the XC5VLX50-2FF676I supports partial reconfiguration through Xilinx ISE tools and associated bitstream generation flow. This capability allows runtime modification of designated logic regions without resetting the entire device, critical for applications like adaptive radar waveform switching or hot-swappable protocol engines. Implementation requires careful floorplanning and use of the PlanAhead toolset.

What configuration modes are available for XC5VLX50-2FF676I?

The XC5VLX50-2FF676I supports multiple configuration modes including Master SelectMAP, Slave SelectMAP, JTAG, and Slave Serial. Mode selection is determined by M0–M2 pin states at power-up. Master SelectMAP enables autonomous boot from SPI flash, while JTAG is used for debugging and programming during development. All modes are documented in UG191 (Virtex-5 Configuration User Guide).

Is XC5VLX50-2FF676I qualified for extended temperature operation?

Yes, the XC5VLX50-2FF676I is rated for industrial temperature range (–40°C to +100°C junction), as indicated by the "I" suffix in the part number. This qualification includes guaranteed timing performance at the –2 speed grade under worst-case voltage (0.95 V) and temperature conditions, making it suitable for harsh-environment deployments such as airborne radar and downhole oilfield equipment.

How many RocketIO GTP transceivers does XC5VLX50-2FF676I integrate?

The XC5VLX50-2FF676I integrates 12 RocketIO GTP transceivers, each capable of 100 Mbps to 2.5 Gb/s operation. These transceivers support PCIe Gen1 endpoints, Serial RapidIO, and custom high-speed serial protocols. They include built-in 8B/10B encoding, clock data recovery, and programmable pre-emphasis, enabling robust signal integrity over FR4 PCB traces up to 20 inches.
