AMD XCV400-6HQ240C

Overview

XCV400-6HQ240C from Xilinx is a 2.5 V SRAM-based Field Programmable Gate Array (FPGA) with 468,252 system gates, 10,800 logic cells, and 404 maximum user I/O pins in a 240-pin High Heat Dissipation Quad Flat Pack (HQ240) package. It features four delay-locked loops (DLLs), hierarchical memory (including 81,920 bits of block SelectRAM), and supports 66-MHz PCI compliance for high-speed embedded control and interface bridging applications.

For engineers reviewing the XCV400-6HQ240C datasheet, pinout, applications, or equivalent options, this page delivers verified architecture details, I/O banking constraints, CLB-level timing behavior, and real-world FPGA integration considerations for legacy industrial and telecom infrastructure designs.

Technical Context

The XCV400-6HQ240C implements a hierarchical routing architecture with a General Routing Matrix (GRM), local VersaBlock interconnect, and peripheral VersaRing I/O routing-enabling efficient place-and-route for complex synchronous designs up to 200 MHz. Its CLBs contain dual-slice logic with 4-input LUTs, dedicated carry chains, and F5/F6 multiplexers supporting 5- to 19-input functions.

Each IOB supports 16 SelectIO™ standards-including LVTTL, HSTL Class IV, SSTL3, and GTL-with independent programmable drive strength (up to 24 mA source / 48 mA sink), slew rate control, and per-bank VCCO/VREF management across eight I/O banks. Configuration occurs via master serial, slave serial, SelectMAP™, or JTAG modes using external PROM or host controller.

FAQ

What is the maximum operating frequency supported by XCV400-6HQ240C?

XCV400-6HQ240C supports synchronous system clock rates up to 200 MHz, including I/O paths, as guaranteed by its -6 speed grade. This figure reflects worst-case timing under commercial temperature conditions (0°C to +85°C) and accounts for internal routing delays, CLB propagation, and I/O setup/hold constraints across all supported standards like HSTL Class IV and PCI 66 MHz.

Does XCV400-6HQ240C support hot-swap functionality?

Yes, XCV400-6HQ240C supports hot-swapping requirements for Compact PCI systems. Its I/O architecture includes robust electrostatic discharge (ESD) protection, controlled slew-rate drivers, and configurable weak-keeper circuits that maintain valid logic states during insertion/removal-ensuring safe operation in live-backplane environments without disrupting adjacent slots.

How many block RAMs does XCV400-6HQ240C include, and what are their configurations?

XCV400-6HQ240C includes 20 block SelectRAMs totaling 81,920 bits. Each block is a fully synchronous dual-ported 4,096-bit RAM with independent address/data buses per port. Configurable aspect ratios range from 1×4096 to 16×256, enabling flexible data buffering, FIFOs, and lookup tables without consuming CLB resources.

Can XCV400-6HQ240C interface directly with DDR SDRAM?

Yes, XCV400-6HQ240C supports DDR SDRAM interfacing through its SelectIO™ I/O standards, specifically SSTL2 Class I/II (2.5 V) and SSTL3 Class I/II (3.3 V). The device provides precise timing control via DLLs, programmable output drive strength, and per-bank VCCO/VREF management-enabling reliable 133 MHz DDR data rates with proper PCB layout and termination.

Is XCV400-6HQ240C still in active production?

No, XCV400-6HQ240C is obsolete per Xilinx documentation (DS003-1 v4.0, March 2013). However, Aetrix Electronics maintains legacy inventory and offers extended lifecycle support-including traceable sourcing, counterfeit mitigation, and obsolescence forecasting-to sustain production for existing industrial and telecom systems.
