Product details
Overview
XCV400E-7PQ240I from Xilinx is a 1.8 V SRAM-based Field Programmable Gate Array with 569,952 system gates, 10,800 logic cells, and 40 block RAMs totaling 163,840 bits. It features eight digital Delay-Locked Loops (DLLs), supports LVDS/BLVDS/LVPECL differential I/O up to 622 Mb/s, and targets high-speed communication infrastructure and embedded processing applications.
For engineers reviewing the XCV400E-7PQ240I datasheet, pinout, applications, or equivalent options, this device delivers verified 133 MHz internal register-to-register performance, PCI-compliant 3.3 V I/O, 240 MHz synchronous system clock capability, and industrial temperature operation (–40°C to +100°C) in a 240-pin PQFP package.
Technical Context
The XCV400E-7PQ240I implements a regular array architecture of Configurable Logic Blocks (CLBs) and Input/Output Blocks (IOBs) interconnected by a General Routing Matrix (GRM) and VersaRing peripheral routing. Each CLB contains four logic cells with 4-input LUTs, dedicated carry chains, and dual flip-flops per slice with independent clock enable, set/reset, and polarity control.
Its IOBs support 20 interface standards-including LVTTL, LVCMOS2, SSTL3, HSTL, PCI, LVDS, and LVPECL-organized across eight voltage-defined I/O banks. Each bank requires shared VCCO for output standards and optional VREF for input thresholding, with strict banking rules governing mixed-standard placement.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| System Gates | 569,952 - defines total logic capacity for ASIC replacement or complex digital system integration |
| Logic Cells | 10,800 - provides granular, routable logic resources for high-utilization designs with minimal timing closure risk |
| Block RAM Bits | 163,840 - enables true dual-port memory configurations up to 4096 × 40 bits per block for FIFOs or buffer management |
| DLL Count | 8 - supports independent clock domain management, zero-delay clock conversion, and DDR timing alignment |
| Max I/O Pins | 404 user I/O - includes up to 344 differential I/O pairs for >100 Gb/s aggregate bandwidth in source-synchronous interfaces |
| Speed Grade | -7 - guarantees worst-case 4.3 ns register-to-register delay and 6.3 ns adder delay at industrial temperature |
| Supply Voltage | VCCINT = 1.8 V - reduces dynamic power vs. 2.5 V Virtex, while VCCO = 3.3/2.5/1.8 V enables mixed-voltage I/O banking |
Pinout & Package
The XCV400E-7PQ240I uses a 240-pin Plastic Quad Flat Pack (PQFP) package with 0.5 mm pitch and 32.5 mm × 32.5 mm body size. Pin assignments follow Xilinx DS022-4 Module 4 pinout tables, with dedicated global clocks (GCLK0–GCLK3), configuration pins (INIT, PROGRAM, DONE), JTAG boundary scan (TCK/TMS/TDI/TDO), and 404 user I/O distributed across eight banks.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GCLK0–GCLK3 | Global Clock Inputs | Low-skew primary clock inputs routed directly to DLLs; require external termination for LVPECL/LVDS |
| INIT, PROGRAM, DONE | Configuration Control | Asynchronous initialization, reconfiguration trigger, and configuration completion status signals |
| TCK/TMS/TDI/TDO | JTAG Boundary Scan | IEEE 1149.1-compliant test access port supporting device programming and interconnect verification |
| VCCINT, VCCO_0–VCCO_7 | Power Supplies | VCCINT = 1.8 V core supply; each VCCO_n powers one I/O bank and sets output voltage level |
| VREF_0–VREF_7 | Input Threshold Reference | Bank-specific reference voltage for SSTL/HSTL/LVCMOS input buffers; must be externally supplied and stable |

Equivalent & Alternatives
The following parts are listed as comparable options for similar FPGA-based system integration applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| XCV400E-8PQ240I | Higher speed grade (-8) with 3.8 ns register-to-register delay vs. 4.3 ns for -7 grade; identical logic density, I/O count, and package | Suitable for designs requiring tighter timing margins or higher clock frequencies beyond 133 MHz internal operation | Select when worst-case timing closure fails on -7 grade or when migrating from prototype to production with margin headroom |
| XCV600E-7PQ240I | Higher density (186,624 logic cells vs. 10,800), larger block RAM (294,912 bits), same -7 speed grade and PQ240 package footprint | Required for designs exceeding 10,800 logic cells or needing >163,840-bit memory, but demands PCB redesign due to different pinout | Choose only if logic utilization exceeds 90% on XCV400E-7PQ240I; not pin-compatible - requires layout revision and timing revalidation |
Compared with XCV400E-8PQ240I, the XCV400E-7PQ240I trades 0.5 ns timing margin for lower cost and power; compared with XCV600E-7PQ240I, it offers identical speed and package compatibility at reduced logic capacity and memory - making it optimal for cost-sensitive, mid-density applications where pinout stability is critical.

FAQ
What is the maximum operating temperature range for the XCV400E-7PQ240I?
The XCV400E-7PQ240I is rated for industrial temperature operation from –40°C to +100°C junction temperature. This specification is confirmed in the Virtex-E Ordering Information section of DS022-1 (v2.3), where the "I" suffix explicitly denotes the industrial temperature grade. The device undergoes 100% factory testing under these thermal conditions.
Does the XCV400E-7PQ240I support LVDS signaling, and what is its maximum data rate?
Yes, the XCV400E-7PQ240I supports LVDS signaling as part of its SelectI/O+™ technology, with a maximum data rate of 622 Mb/s per differential pair. This is documented in the Features section of DS022-1 and validated in Table 2 performance data for chip-to-chip LVDS interfaces under worst-case timing conditions.
How many block RAMs does the XCV400E-7PQ240I contain, and what is their configuration capability?
The XCV400E-7PQ240I contains 40 block RAMs, totaling 163,840 bits. Each block is a true dual-port 4096-bit RAM with independently configurable data widths per port, enabling built-in bus-width conversion and simultaneous read/write operations - as specified in Table 4 of DS022-2 (v2.8).
Is the XCV400E-7PQ240I pin-compatible with other Virtex-E devices in the PQ240 package?
No - the XCV400E-7PQ240I is not universally pin-compatible with other Virtex-E devices in the PQ240 package. While XCV50E through XCV400E share the PQ240 option, pinouts differ across densities due to varying I/O counts and bank allocations; DS022-4 explicitly lists distinct pin assignments for each device in this package.
What development tools support the XCV400E-7PQ240I, and is it compatible with modern toolchains?
The XCV400E-7PQ240I is natively supported by Xilinx Foundation Series™ and Alliance Series™ design tools, as stated in DS022-1. While not supported in current Vivado, it remains fully functional with legacy ISE 14.7 and earlier versions. Bitstream generation, place-and-route, and simulation workflows are validated for this device in those environments.
