• I/O and Package — 488 user I/O pins in a 780-BBGA FCBGA (supplier device package: 780-FBGA, 29×29) with surface-mount mounting for high-density board designs.
• Voltage and Power — Selectable core voltage operation with supply range from 0.860 V to 1.150 V, enabling trade-offs between performance and power.
• Temperature and Grade — Industrial operating range from −40 °C to 100 °C; RoHS compliant.
• DSP Capabilities — Series architecture includes dedicated high-speed DSP blocks supporting 9×9, 12×12, 18×18, and 36×36 multipliers for multiply-accumulate and FIR filter implementations.
• Clocking and PLLs — Support for up to 16 global clocks, 88 regional clocks, 116 peripheral clocks, and up to 12 phase-locked loops (PLLs) for flexible clock management and synthesis.
• Memory Interface and High-speed I/O — Series-level support for DDR-family memory interfaces and high-speed differential I/O with serializer/deserializer (SERDES) and dynamic phase alignment features.
• Security and Reliability — Series options include 256-bit AES encryption for configuration bitstream protection and configuration memory error detection (CRC) with built-in error detection and correction mechanisms for on-chip memory.

Typical Applications

• High-performance DSP Systems — Implement FIR filters, transforms, and multiply-accumulate engines using the device’s dedicated DSP blocks and abundant logic resources.
• Networking and Communications — Use high-speed differential I/O and SERDES support for protocol processing, packet handling, and interface bridging.
• Memory Interface Controllers — Leverage the embedded RAM and memory-interface support to build DDR/DDR2/DDR3 and specialized SRAM controller logic.
• Embedded and Prototype Systems — Combine configurable logic, on-chip memory, and PLL-based clock management for system integration and evaluation platforms.

Unique Advantages

• Substantial Logic and Memory in a Single Device: 47,500 logic elements and approximately 2.18 Mbits of embedded RAM reduce the need for external logic and memory, simplifying BOM and board layout.
• Flexible Power/Performance Trade-offs: Selectable core voltage and Programmable Power Technology allow designers to optimize for either higher performance or lower power consumption within the 0.860–1.150 V supply range.
• Robust I/O and Packaging: 488 user I/Os in a 780-ball FCBGA (29×29) package deliver high pin-count connectivity for dense system designs while supporting surface-mount assembly.
• Advanced DSP and Clocking Resources: Dedicated multiplier blocks and extensive clocking resources (global/regional/peripheral clocks plus up to 12 PLLs) enable precise timing control and high-throughput signal processing.
• Industrial Temperature Range: Rated from −40 °C to 100 °C to support demanding operating environments.
• Built-in Security and Reliability Features: Support for AES-based configuration protection and on-chip error detection/correction improves system integrity and uptime.
