AMD XCV400E-6PQ240I

Overview

XCV400E-6PQ240I from Xilinx is a 1.8 V SRAM-based Field Programmable Gate Array with 569,952 system gates, 10,800 logic cells, and 404 user I/O pins in a 240-pin PQ (Plastic Quad Flat) package. It features eight digital Delay-Locked Loops (DLLs), 163.84 kb of true dual-port block RAM, and supports LVDS, LVPECL, and PCI-compliant 3.3 V interfaces up to 622 Mb/s - deployed in high-speed communications and industrial control systems.

For engineers reviewing the XCV400E-6PQ240I datasheet, pinout, applications, or equivalent options, this page delivers verified architecture details, I/O banking constraints, DLL timing behavior, block RAM configuration modes, and speed-grade–specific DC/AC characteristics for production-level FPGA integration and migration planning.

Technical Context

The XCV400E-6PQ240I implements a regular array architecture with configurable logic blocks (CLBs) containing four logic cells each, two slices per CLB, and dedicated carry chains enabling high-speed arithmetic. Each CLB integrates 4-input LUTs usable as 16×1-bit synchronous RAM or 16-bit shift registers, plus dual BUFTs for internal bus driving.

I/O functionality is organized into eight banks with independent VCCO and VREF supply domains; input buffers for LVTTL/LVCMOS2/PCI standards are powered by VCCO (not VCCINT), and differential standards like LVDS/LVPECL require matched termination and support 300+ MHz clock inputs via dedicated DLLs. The -6 speed grade guarantees 130 MHz internal performance (four LUT levels) and 240 MHz system clock operation with source-synchronous I/O.

Key Specifications

FAQ

What is the maximum differential I/O pair count supported by XCV400E-6PQ240I?

XCV400E-6PQ240I supports up to 183 differential I/O pairs in the PQ240 package, as confirmed in Table 1 and Table 3 of DS022-1 (v2.3). This enables implementation of 183 LVDS channels or 92 LVPECL pairs with proper termination, meeting bandwidth requirements for parallel video or multi-lane data acquisition systems.

Does XCV400E-6PQ240I support 5 V-tolerant I/O?

XCV400E-6PQ240I does not natively support 5 V-tolerant I/O. Its I/O pins are rated for 3.3 V operation and tolerate up to 3.6 V absolute maximum. For 5 V interfaces, an external 100 Ω series resistor is required per pin, as specified in the General Description section of DS022-1 - PCI 5 V signaling is explicitly unsupported.

How many DLLs are integrated into XCV400E-6PQ240I and what clock frequencies do they support?

XCV400E-6PQ240I integrates eight fully digital Delay-Locked Loops (DLLs), as stated in the Features section of DS022-1. Each DLL accepts LVPECL or LVDS clock inputs up to 300+ MHz, provides 4× frequency multiplication, and generates 50% duty cycle outputs - essential for DDR memory interfaces and high-speed serial links.

Is XCV400E-6PQ240I pin-compatible with earlier Virtex family FPGAs?

XCV400E-6PQ240I is not bitstream-compatible with Virtex family devices, but the same package variant (e.g., PQ240) is pin-compatible with Virtex devices with minor exceptions - detailed in the "Virtex-E Compared to Virtex Devices" section of DS022-1. Critical differences include VCCO-powered I/O buffers and revised banking rules.

What is the block RAM configuration capability of XCV400E-6PQ240I?

XCV400E-6PQ240I contains 40 block RAMs totaling 163,840 bits, each configurable as true dual-port memory with independent read/write addresses and data widths. As documented in DS022-2 Module 2, this enables simultaneous access for applications such as ping-pong buffering, FIFOs, or memory-mapped peripheral interfaces without external SRAM.
