• Package & Thermal  484-BBGA package with commercial-grade operating temperature of 0°C to 85°C.
• System-Level Support  IEEE 1149.1 boundary scan, JTAG configuration and onboard oscillator. Built-in capabilities for in-field logic update and internal logic analysis.
• Reconfiguration Features  TransFR™ reconfiguration for in-field updates and system configuration via JTAG and configuration ports.

Typical Applications

• High-speed memory interfaces  Use the device's dedicated DDR support and abundant embedded memory for DDR controller logic and external memory bridging.
• Communications and networking  High I/O count and multi-standard I/O buffers make the device suitable for protocol bridging, interface aggregation and I/O-heavy front-end logic.
• Embedded control and signal processing  Implement custom control logic, peripheral interfaces and local buffering using the device's logic elements and on-chip RAM.
• Field-updatable systems  TransFR reconfiguration and instant-on capability enable in-field logic updates and fast restart behavior for deployed equipment.
• Test, measurement and prototyping  Boundary-scan, onboard oscillator and internal logic analysis capabilities aid system bring-up, debugging and iterative development.

Unique Advantages

• Instant-on non-volatile operation: Eliminates the need for external configuration memory and enables rapid power‑up.
• Flexible, high-density I/O: Up to 300 I/Os and programmable sysIO buffers support a wide range of signaling standards to minimize additional interface components.
• Embedded memory for buffering and local data: Approximately 331,776 bits of on-chip RAM provide immediate storage for low-latency functions and data paths.
• In-field reconfiguration: TransFR capability and JTAG-based configuration let you update logic while the system remains in service.
• Comprehensive clocking support: Up to four analog PLLs enable flexible clock management, frequency synthesis and phase adjustments within the device.
• Low-power options: Sleep Mode offers substantial static current reduction for power-sensitive designs.
