What Is the XCV300E-6PQG240C?

The XCV300E-6PQG240C is a member of the Xilinx Virtex-E 1.8 V FPGA family — an evolutionary advancement over the original Virtex series. The “6” in the part number denotes the speed grade, “PQG240” identifies the 240-pin Plastic Quad Flat Pack (PQFP) package variant, and “C” indicates commercial temperature range operation (0°C to +85°C).

This device is built on a 6-layer metal 0.18 µm CMOS process technology, which delivers exceptional silicon efficiency by optimizing the architecture for place-and-route performance. The result is a programmable logic solution competitive with mask-programmed gate arrays in both speed and density.

Note: The XCV300E-6PQG240C is not recommended for new designs (NRND). Engineers designing new systems should evaluate current-generation Xilinx/AMD FPGA families. However, this part remains widely used in maintenance, legacy system support, and production runs already qualified on this device.

Architecture & Features

High-Density Configurable Logic Blocks (CLBs)

The XCV300E-6PQG240C contains 1,536 CLBs, each consisting of two slices. Each slice provides two 4-input Look-Up Tables (LUTs) configurable as:

• 16-bit RAM
• 32-bit RAM
• 16-bit dual-ported RAM
• 16-bit shift register

This flexibility allows designers to implement complex logic, memory-mapped registers, and FIFOs directly within the CLB fabric — reducing resource overhead and maximizing utilization.

Block RAM – Hierarchical Memory System

The device integrates 16 dedicated synchronous dual-port 4K-bit Block RAMs, providing a total of 131,072 bits (16 KB) of true dual-port on-chip memory. These block RAMs:

• Support independent read and write operations on both ports simultaneously
• Operate at full device speed
• Provide fast interfaces to external high-performance SRAMs and ZBTRAMs
• Eliminate the need for external memory in many small data-buffer applications

Clock Management with Delay-Locked Loops (DLLs)

The XCV300E-6PQG240C features four dedicated Delay-Locked Loops (DLLs) that provide advanced clock management capabilities, including:

• Clock deskew and duty-cycle correction
• Clock multiplication and division
• Phase shifting for source-synchronous designs
• Low-skew global clock distribution over four primary clock nets and 24 secondary local clock nets

SelectIO™ Multi-Standard Interface Support

One of the standout features of the Virtex-E family is the SelectIO™ interface technology, supporting up to 16 high-performance I/O standards. This allows the XCV300E-6PQG240C to interface directly with a wide variety of logic families and memory devices without external level translators.

PCI Compliance & Hot-Swap Support

The XCV300E-6PQG240C is 66 MHz PCI compliant and supports hot-swapping for CompactPCI applications. This makes it directly suitable for bus-based industrial computer architectures where live board insertion and removal is required.

Configuration & Programming

The XCV300E-6PQG240C supports multiple configuration modes to suit different system architectures:

• Master Serial – Uses a serial PROM (e.g., Xilinx XC18V series)
• Slave Serial – Configured by an external controller
• Master Parallel – Uses a byte-wide parallel PROM
• Slave Parallel – For processor-driven configuration
• JTAG Boundary Scan – IEEE 1149.1 compliant for in-system programming and testing

Recommended Design Tools

Note: Xilinx Vivado does not support Virtex-E devices. Use the ISE 14.7 toolchain (the final ISE release) for XCV300E-6PQG240C design and programming.

Design Considerations & PCB Guidelines

When designing with the XCV300E-6PQG240C, the following PCB and power supply guidelines help ensure reliable operation:

• Decouple VCCINT and VCCIO with 100 nF ceramic capacitors placed as close as possible to each power pin, supplemented by bulk electrolytic capacitors on the power planes.
• Separate VCCINT (1.8 V) and VCCIO (variable) power rails to allow independent I/O voltage selection per bank.
• Use matched-length traces for differential I/O pairs (LVDS, LVPECL) to minimize skew.
• HSPQFP thermal management: The heat spreader pad on the top of the package can be used with a clip-on heatsink for thermally demanding applications.
• JTAG chain placement: Position the JTAG header close to the FPGA for reliable boundary scan access during production test.
