AMD XC2VP20-7FG676C

Overview

XC2VP20-7FG676C from Xilinx is a Virtex-II Pro platform FPGA integrating two PowerPC 405 RISC processor blocks, eight RocketIO multi-gigabit transceivers (2.5 Gb/s max in wire-bond FG676 package), 20,880 logic cells, twelve Digital Clock Managers (DCMs), and 564 user I/Os in a 676-pin fine-pitch BGA. It targets high-bandwidth telecom backplane interfaces requiring embedded processing and serial connectivity.

For engineers reviewing the XC2VP20-7FG676C datasheet, pinout, applications, or equivalent options, key selection criteria include dual PowerPC 405 core support at up to 400 MHz, RocketIO transceiver compatibility with Fibre Channel and Gigabit Ethernet, DCM-based clock deskew and phase shifting, and SelectIO-Ultra I/O supporting LVDS, SSTL, and DCI termination.

Technical Context

The XC2VP20-7FG676C implements a hybrid architecture combining hard IP blocks (dual PowerPC 405 cores, eight RocketIO transceivers) with programmable FPGA fabric based on 0.13 µm copper process. Its RocketIO transceivers operate at 2.5 Gb/s in the FG676 wire-bond package and support 8B/10B encoding, channel bonding, and programmable pre-emphasis.

Each PowerPC 405 block includes 16 KB instruction and 16 KB data caches, MMU with 64-entry TLB, and OCM interface for low-latency memory access. The FPGA fabric delivers 20,880 logic cells, 290 18×18 multipliers, 88 Block SelectRAM+ modules (18 Kb each), and twelve DCMs enabling precise clock de-skew, frequency synthesis, and ±1/256-cycle phase adjustment.

Key Specifications

Pinout & Package

Manufacturer

Xilinx, now part of AMD, pioneered FPGA technology and developed the Virtex family for high-performance system-on-chip applications before its acquisition in 2022.

The Virtex-II Pro product line was engineered to integrate embedded processors and high-speed serial transceivers into programmable logic, targeting communications infrastructure and signal-intensive embedded systems.

FAQ

What is the maximum operating frequency of the PowerPC 405 cores in XC2VP20-7FG676C?

The XC2VP20-7FG676C supports PowerPC 405 cores running at up to 400 MHz in -7 speed grade Commercial devices. This requires adherence to XAPP755 guidelines when both cores operate above 350 MHz. The actual achievable frequency depends on clock routing, voltage stability, and thermal conditions in the final PCB design. XC2VP20-7FG676C documentation confirms this rating applies specifically to the dual-core configuration under specified VCCINT and ambient conditions.

Does XC2VP20-7FG676C support partial reconfiguration?

Yes, XC2VP20-7FG676C supports partial reconfiguration through its SRAM-based configuration architecture and dedicated configuration logic. This allows dynamic swapping of functional modules in the FPGA fabric without resetting the entire device or interrupting PowerPC core operation. Implementation requires Xilinx ISE tools and proper floorplanning; XC2VP20-7FG676C's configuration interface (SelectMAP or JTAG) enables targeted bitstream loading to defined reconfigurable regions.

What I/O standards are supported by XC2VP20-7FG676C's SelectIO-Ultra blocks?

XC2VP20-7FG676C supports 22 single-ended standards (including LVCMOS 1.5V/1.8V/2.5V/3.3V, PCI, GTL, HSTL, SSTL) and 10 differential standards (LVDS, BLVDS, ULVDS, LVPECL, LDT). Each I/O bank is independently configurable, and Digitally Controlled Impedance (DCI) provides on-chip termination for single-ended standards. XC2VP20-7FG676C's IOB structure also supports DDR input/output registers and built-in differential termination for LVDS and related standards.

Can XC2VP20-7FG676C be used in new designs despite its "Not Recommended For New Designs" status?

XC2VP20-7FG676C is marked "Product Not Recommended For New Designs" per Xilinx DS083 v5.0 (2011), indicating it has been superseded by newer families like Virtex-4, Virtex-5, or Kintex. However, Aetrix Electronics maintains inventory and supply chain support for legacy systems requiring replacement or maintenance. XC2VP20-7FG676C remains viable for sustaining engineering, repair, or life-extended deployments where redesign is impractical or cost-prohibitive.

What is the role of the Digital Clock Manager (DCM) in XC2VP20-7FG676C?

The XC2VP20-7FG676C integrates twelve Digital Clock Managers (DCMs) that provide fully digital clock deskewing, frequency synthesis (multiplication/division), and fine-grained phase shifting (±1/256 cycle resolution). Each DCM accepts a single input clock and generates multiple synchronized outputs, enabling precise timing control across PowerPC cores, RocketIO transceivers, and FPGA fabric logic. XC2VP20-7FG676C's DCMs eliminate need for external PLLs and support jitter reduction critical for high-speed serial links and synchronous memory interfaces.
