Designed for demanding digital logic applications, this device delivers 100K system gates, 2,700 logic cells, and a top speed grade of -7, making it one of the fastest variants in the XCV100E lineup. Housed in a compact 240-pin BQFP (Bumpered Quad Flat Package) with gull-wing leads, it is ideal for engineers who need proven, high-density programmable logic in a surface-mount form factor.
Whether you are working on telecommunications, industrial control, signal processing, or embedded computing, the XCV100E-7PQG240C provides a robust and flexible solution backed by Xilinx’s industry-standard 0.18 µm CMOS process technology.
What Is the XCV100E-7PQG240C?
The XCV100E-7PQG240C is a member of the Xilinx Virtex-E 1.8V FPGA family — an evolutionary step forward from the original Virtex series. The “-7” in the part number denotes its speed grade (the fastest commercially available grade in this family), “PQG240” refers to the 240-pin Plastic Quad Flat Package with guard ring, and “C” indicates a commercial temperature range (0°C to +85°C junction temperature).
This device uses a 6-layer metal, 0.18 µm CMOS process, delivering dramatic improvements in speed and density compared to earlier generations. Its architecture is optimized for place-and-route efficiency, giving design engineers predictable timing closure and reduced time-to-market.

XCV100E-7PQG240C Architecture Overview
#### Configurable Logic Blocks (CLBs)
The Virtex-E CLB architecture consists of 4 slices per CLB, each containing two 4-input Look-Up Tables (LUTs), two storage elements (flip-flops or latches), and carry/arithmetic logic. The XCV100E-7PQG240C contains 600 CLBs, totaling 2,700 logic cells. Importantly, each CLB counts as 4.5 logic cells when combining function generators, enabling efficient implementation of 5- and 6-input functions.
#### Block RAM
The device includes 81,920 bits (~80 Kbits / 10 KB) of dedicated block RAM, arranged in 4Kbit dual-port synchronous RAM blocks. These are ideal for FIFOs, lookup tables, local data storage, and shift registers — without consuming CLB resources.
#### I/O Blocks (IOBs)
All 158 user I/O pins are organized into 4 banks, each supporting a separate VCCO supply voltage. This enables mixed-voltage interfaces within a single device. Supported standards include GTL, GTL+, SSTL-2, SSTL-3, HSTL, LVTTL, LVCMOS, AGP, PCI, and CTT — making the XCV100E-7PQG240C suitable for integration with a wide range of external logic families.
#### Clock Management – DLL
The XCV100E-7PQG240C features Delay-Locked Loops (DLLs) for zero-skew clock distribution, frequency synthesis, and clock deskewing. DLLs allow the FPGA to eliminate internal clock distribution delays, ensuring precise timing across the entire device.
#### Boundary Scan (JTAG)
Full IEEE 1149.1 JTAG boundary scan is supported, enabling in-system testing, device programming, and debugging without physical test probes. The boundary scan register provides three bits per IOB (Input, Output, 3-State Control).

Frequently Asked Questions (FAQ)
What is the difference between XCV100E-7PQG240C and XCV100E-6PQG240C?
The only difference is the speed grade. The XCV100E-7PQG240C is rated at speed grade -7, delivering higher maximum clock frequencies (~357 MHz) compared to the XCV100E-6PQG240C at speed grade -6 (~333 MHz). Both devices share identical logic resources, I/O counts, and packaging.
Is the XCV100E-7PQG240C RoHS compliant?
No. As a legacy FPGA device produced under older manufacturing processes, the XCV100E-7PQG240C is not RoHS compliant. Engineers requiring RoHS-compliant FPGAs should evaluate newer Xilinx families such as the Spartan-6 or Artix-7 series.
What configuration PROM is compatible with the XCV100E-7PQG240C?
Xilinx XCF (Platform Flash) PROMs and legacy XC1700E / XC18V series configuration PROMs are compatible. For serial configuration, the XCF01S (1 Mbit) is commonly used with the XCV100E.
Can the XCV100E-7PQG240C be used in industrial temperature environments?
The “C” suffix in the part number indicates a commercial temperature range (0°C to +85°C TJ). For industrial environments (–40°C to +100°C), the XCV100E-7PQ240I (or similar “I” suffix variant) should be specified instead.
What is the difference between the PQG and PQ packages for the XCV100E?
Both the PQG and PQ designations refer to 240-pin Quad Flat Pack packages. The PQG includes a guard ring (bumpers on the corners), which provides added mechanical protection against package damage during handling and PCB assembly — a practical consideration for high-volume production environments.
