Key Features

• Core Architecture 2400 configurable logic blocks (CLBs) providing 10,800 logic cells and approximately 468,252 system gates for high-density logic implementation.
• Embedded Memory Approximately 81.9 Kbits of on-chip block RAM (81,920 bits) to support buffering, FIFOs, and local data storage.
• I/O and SelectIO™ Interfaces 166 user I/O pins with multi-standard SelectIO support and a range of high-performance interface standards for flexible board-level connectivity.
• Clock Management Four dedicated delay-locked loops (DLLs) and multiple global and local clock distribution nets for advanced clock control and low-skew distribution.
• Performance and System Compatibility System performance capability up to 200 MHz and 66-MHz PCI compliance; hot-swappable support for Compact PCI environments is indicated in the device family feature set.
• Arithmetic and Logic Support Dedicated carry logic, multiplier support, and cascade chains for efficient implementation of high-speed arithmetic and wide-input functions.
• Configuration and Tool Support SRAM-based in-system configuration with unlimited re-programmability, four programming modes, and development support from the Virtex tool ecosystem.
• Package and Power Surface-mount 240-BFQFP exposed pad package (supplier package: 240-PQFP 32×32) with a nominal supply range of 2.375 V to 2.625 V.
• Operating Conditions and Compliance Commercial grade with an operating temperature range of 0 °C to 85 °C and RoHS compliance.

Typical Applications

• PCI and Compact PCI Systems Implement PCI-compliant interfaces and hot-swappable board functions leveraging the device family’s 66-MHz PCI support and Compact PCI compatibility.
• High-Speed I/O Bridging Use the multi-standard SelectIO interfaces and 166 user I/Os for protocol bridging, custom interface translation, and board-level I/O aggregation.
• Compute and DSP Acceleration Leverage dedicated multiplier support and optimized carry logic to implement arithmetic-heavy kernels and data-path acceleration.
• Embedded Logic and Prototyping Employ the device’s abundant logic cells and reconfigurable SRAM-based configuration for system prototypes, custom control logic, and iterative design development.

Unique Advantages

• High Logic Density: 10,800 logic cells and roughly 468k system gates enable complex logic designs within a single device footprint.
• On-Chip Memory Resources: Approximately 81.9 Kbits of embedded RAM reduces external memory dependency for buffering and local storage.
• Flexible Clocking: Multiple DLLs and hierarchical clock nets allow precise clock control for multi-domain and timing-sensitive designs.
• Broad I/O Capability: 166 user I/Os and multi-standard interface support simplify integration with diverse board-level peripherals and buses.
• Configurable In-System Programming: SRAM-based re-programmability and multiple configuration modes enable iterative updates and design refinement without hardware changes.
• Commercial, RoHS-Compliant Package: Surface-mount 240-BFQFP exposed pad package meets common commercial board-assembly requirements and environmental compliance needs.
