Product details
Overview
XCV400-4HQ240C from Xilinx is a 1.8 V SRAM-based Field Programmable Gate Array (FPGA) with 569,952 system gates and 10,800 logic cells in a 40 × 60 CLB array. It features eight digital Delay-Locked Loops (DLLs), up to 404 user I/O pins in HQ240 package, and supports LVDS (622 Mb/s), LVPECL, and PCI 33/66 MHz interfaces for high-speed data acquisition and telecom line-card applications.
For engineers reviewing the XCV400-4HQ240C datasheet, pinout, applications, or equivalent options, this page delivers verified architecture details, I/O banking constraints, DLL timing behavior, block RAM configuration options, and real-world FPGA integration considerations for legacy Virtex-E system upgrades.
Technical Context
The XCV400-4HQ240C implements a regular array architecture with configurable logic blocks (CLBs) and input/output blocks (IOBs) interconnected via 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.
Its eight fully digital DLLs provide zero-delay clock conversion, 50% duty-cycle synthesis for DDR, and frequency multiplication up to 4×. I/O banks enforce strict VCCO/VREF grouping: LVTTL/LVCMOS inputs are powered by VCCO (not VCCINT), and differential standards like LVDS require 2.5 V VCCO with no VREF.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| System Gates | 569,952 - defines total logic capacity for gate-equivalent synthesis targeting. |
| Logic Cells | 10,800 - actual programmable elements supporting LUT+flip-flop+carry per cell. |
| User I/O Pins | 404 - maximum single-ended I/O count in HQ240 package; banked for mixed-voltage operation. |
| Block RAM Bits | 163,840 - organized as forty 4096-bit true dual-port synchronous RAM blocks. |
| DLL Count | 8 - independent digital delay-locked loops for clock domain bridging and jitter reduction. |
| Max I/O Speed | 622 Mb/s - achievable with LVDS signaling; requires matched trace lengths and proper termination. |
| VCCINT | 1.8 V ± 0.1 V - core logic supply; lower voltage enables reduced dynamic power vs. 2.5 V Virtex. |
Pinout & Package
The XCV400-4HQ240C uses a 240-pin High Heat Dissipation (HQ) plastic quad flat pack (PQFP) package with 0.5 mm pitch and exposed thermal pad. Pinout follows Xilinx DS022-4 Module 4, with dedicated global clocks (GCLK0–GCLK3), configuration pins (INIT, PROGRAM, DONE), JTAG boundary-scan (TCK/TMS/TDI/TDO), and 404 user I/O grouped into eight banks.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GCLK0–GCLK3 | Global Clock Input | Low-skew primary clock inputs routed directly to all DLLs and CLBs; must be LVPECL/LVDS for >300 MHz operation. |
| INIT_B | Configuration Status | Open-drain active-low signal indicating configuration memory readiness; drives external pull-up during startup. |
| PROGRAM_B | Configuration Reset | Active-low asynchronous reset that clears configuration memory and restarts loading sequence. |
| DONE | Configuration Completion | Open-drain output confirming successful bitstream load; used to enable downstream logic after FPGA initialization. |
| TCK/TMS/TDI/TDO | JTAG Boundary Scan | IEEE 1149.1-compliant test interface for in-system programming and interconnect verification. |
Key Features
| Feature | Design Value |
|---|---|
| SRAM-Based In-System Reconfiguration | Unlimited reprogramming cycles without hardware replacement; supports field-upgradable protocols and partial reconfiguration workflows. |
| SelectI/O+™ Technology | Supports 20 I/O standards including LVDS, LVPECL, SSTL, HSTL, and PCI; each bank enforces VCCO/VREF co-location rules. |
| SelectRAM+™ Memory Hierarchy | Combines 163,840 bits of true dual-port block RAM with distributed CLB-based RAM for pipelined buffering and FIFO implementation. |
| SelectLink™ DDR Interface | Proprietary high-speed link enabling double-data-rate communication between Virtex-E devices; requires HDL generation via Web-based tools. |
| Digital DLL Clock Management | Eight DLLs provide deterministic clock deskew, 50% duty cycle correction, and integer frequency multiplication without external PLL components. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar FPGA-based system logic applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| XCV400E-6HQ240C | Higher speed grade (-6 vs. -4); 133 MHz register-to-register timing vs. 125 MHz. | Suitable for designs requiring tighter setup/hold margins or higher clock frequencies. | Select when target system clock exceeds 125 MHz or when worst-case timing closure fails with -4 grade. |
| XCV600E-4HQ240C | Higher density (985,882 gates, 15,552 logic cells); same package and speed grade. | Enables larger state machines, deeper pipelines, or additional protocol stacks without PCB change. | Choose for design scalability where future feature expansion is anticipated within same footprint. |
Compared with XCV400-4HQ240C, the XCV400E-6HQ240C offers faster timing closure at cost of higher power consumption, while the XCV600E-4HQ240C provides headroom for logic growth but requires re-synthesis and may increase static power due to larger die area.

FAQ
What is the maximum operating junction temperature for XCV400-4HQ240C?
The XCV400-4HQ240C is rated for commercial temperature range (0 °C to +85 °C junction). Its C suffix confirms compliance with this specification. Thermal design must ensure junction temperature remains within this limit under worst-case power dissipation, especially when using all 8 DLLs and high I/O toggle rates.
Does XCV400-4HQ240C support JTAG boundary scan testing?
Yes, XCV400-4HQ240C includes full IEEE 1149.1-compliant boundary scan logic. Pins TCK, TMS, TDI, and TDO are dedicated for this function and support device-level interconnect testing, in-system programming, and configuration verification without requiring external test fixtures.
Can XCV400-4HQ240C be configured via slave serial mode?
Yes, XCV400-4HQ240C supports slave serial configuration using the DIN pin synchronized to an external clock on CCLK. This mode allows microcontroller-driven configuration and is commonly used in embedded systems where host processor controls FPGA initialization sequence and bitstream selection.
How many differential I/O pairs does XCV400-4HQ240C support?
XCV400-4HQ240C supports up to 183 differential I/O pairs, as specified in Table 1 of DS022-1. This count assumes use of LVDS or LVPECL standards and accounts for pin pairing constraints within I/O banks; actual usable pairs depend on bank voltage assignments and routing resources.
Is XCV400-4HQ240C pin-compatible with other Virtex-E devices in HQ240 package?
XCV400-4HQ240C shares the same HQ240 pinout with XCV300E-4HQ240C and XCV600E-4HQ240C per DS022-4 Module 4, but functional compatibility requires verifying I/O bank assignments, VCCO requirements, and DLL usage. Unused pins may differ across densities, affecting PCB reuse.
