• High I/O count — 976 general-purpose I/Os to support wide external connectivity and complex board-level interfaces.
• High-speed I/O and transceiver features — the Stratix IV Device Handbook lists high-speed differential I/O capabilities and high-speed transceiver features suitable for demanding data paths and protocol support.
• Signal processing and clocking — device family documentation includes DSP block resources, PLLs and extensive clock network features for synchronized, deterministic designs.
• Low-voltage core operation — core supply range from 870 mV to 930 mV for optimized power-domain design.
• Industrial grade and temperature range — specified for industrial operation from −40 °C to 100 °C.
• Package and mounting — supplied in a 1517-BBGA (1517-HBGA, 42.5 × 42.5 mm) surface-mount package to support high-density PCB implementations.
• Environmental compliance — RoHS compliant.

Typical Applications

• High-bandwidth networking — leverage the large logic count and high-speed I/O/transceiver features for packet processing, protocol bridging and network acceleration.
• Signal and image processing — use the substantial logic and approximately 34 Mbits of embedded memory together with DSP resources for real-time processing pipelines.
• Industrial control and automation — industrial-grade temperature range and high I/O count enable robust control, sensor aggregation and communication tasks in industrial systems.
• System integration and memory interfacing — extensive I/O and documented external memory interface support simplify designs that require large external memory and multiple peripheral buses.
