Product details
Overview
XCV400E-7PQ240C 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 (163,840 bits). It features eight digital Delay-Locked Loops (DLLs), supports LVDS/BLVDS/LVPECL differential I/O up to 622 Mb/s, and operates at -7 speed grade in commercial temperature range (0°C to +85°C) within a 240-pin PQFP package. It is used in high-speed communication interface bridging and reconfigurable signal processing subsystems.
For engineers reviewing the XCV400E-7PQ240C datasheet, pinout, applications, or equivalent options, this page delivers verified architecture details, I/O banking constraints, DLL timing behavior, SelectRAM+ memory configuration, and precise package-level routing compatibility for Virtex-E family migration paths.
Technical Context
The XCV400E-7PQ240C implements a regular array of Configurable Logic Blocks (CLBs) - each containing four 4-input LUTs, dedicated carry chains, and dual flip-flops per slice - interconnected via a General Routing Matrix (GRM) and peripheral VersaRing™ I/O routing. Its IOBs support 20 I/O standards including PCI-compliant 3.3 V, SSTL, HSTL, and differential LVDS with bank-specific VCCO/VREF constraints.
It integrates 40 × 4096-bit synchronous block RAMs (True Dual-Port), 153,600 bits of distributed RAM, and eight fully digital DLLs enabling zero-delay clock conversion, 50% duty-cycle synthesis for DDR, and 4× frequency multiplication. Internal logic runs at 1.8 V (VCCINT), while I/O banks are independently powered by VCCO (1.5–3.3 V), with input buffers for LVTTL/LVCMOS/PCI supplied by VCCO-not VCCINT.
Key Specifications

| Supply Voltage (VCCINT) | 1.8 V ± 0.1 V - defines core logic and memory operating voltage; lower than Virtex family's 2.5 V |
Pinout & Package
PQ240 is a 240-pin Plastic Quad Flat Pack (PQFP) package with 0.5 mm lead pitch, JEDEC MS-026 compliant, thermally enhanced for commercial-temperature FPGA operation. Pin assignments follow Virtex-E Module 4 pinout tables, with dedicated global clocks (GCLK0–GCLK3), JTAG boundary-scan (TCK/TMS/TDI/TDO), and bank-specific VCCO/VREF pins.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GCLK0–GCLK3 | Global Clock Input | Four dedicated low-skew clock inputs routed directly to DLLs; require external termination for LVPECL/LVDS |

| VCCO_0–VCCO_7 | I/O Bank Power Supply | Eight independent VCCO pins (one per I/O bank); must be set to same voltage for all standards in that bank |
| VREF_0–VREF_7 | Input Threshold Reference | Bank-specific reference voltage inputs for SSTL/HSTL/GTL; internally tied together per bank |
| IO_LxxN/IO_LxxP | Differential I/O Pair | LVDS/BLVDS-capable pin pairs; N/P naming denotes true/complement; require matched trace lengths |

FAQ
What is the maximum differential I/O pair count supported by XCV400E-7PQ240C?
XCV400E-7PQ240C supports up to 183 differential I/O pairs according to Table 1 in DS022-1, but the PQ240 package physically limits usable I/O to 158 single-ended pins. Since differential operation consumes two pins per pair, the practical maximum in PQ240 is 79 differential pairs - constrained by package pin count and bank allocation rules, not device capability.
Does XCV400E-7PQ240C support 5 V tolerant I/O?
No, XCV400E-7PQ240C does not support native 5 V tolerant I/O. Its I/O pins are 3 V tolerant, and can be made 5 V tolerant only with an external 100 Ω series resistor per pin - as stated in DS022-1 Module 1. PCI 5 V signaling is explicitly unsupported, and no internal clamping diodes connect to 5 V rails.
Can XCV400E-7PQ240C be configured via JTAG in-system?
Yes, XCV400E-7PQ240C supports IEEE 1149.1 JTAG boundary-scan configuration in-system. The TCK, TMS, TDI, and TDO pins enable full bitstream loading, verification, and debug without requiring external PROM. JTAG mode is one of four supported configuration methods, alongside master serial, slave serial, and SelectMAP™.
Is XCV400E-7PQ240C pin-compatible with earlier Virtex family devices?
XCV400E-7PQ240C is not bitstream-compatible with Virtex devices, but the same package variant (e.g., PQ240) is pin-compatible with corresponding Virtex devices - subject to minor exceptions documented in the pinout section of DS022-4. Critical differences include VCCINT = 1.8 V (vs. 2.5 V) and I/O buffer power sourcing from VCCO instead of VCCINT.
What clock frequencies can the DLLs in XCV400E-7PQ240C generate?
The eight DLLs in XCV400E-7PQ240C support clock multiplication up to 4×, division, and zero-delay conversion. With LVPECL/LVDS inputs exceeding 300 MHz, they generate internally aligned clocks up to 240 MHz system frequency - confirmed by Table 2 timing data and "Higher Performance" section in DS022-1. Duty cycle correction ensures 50% stability for DDR applications.
