• Embedded Memory Approximately 34 Mbits of on-chip RAM to support buffers, FIFOs, and local data storage without external memory for many functions.
• I/O and Connectivity 1,120 user I/Os to enable wide parallel interfaces and dense connectivity to peripherals and external devices.
• Power Core voltage supply range of 870 mV to 930 mV, allowing designers to plan power delivery and sequencing to meet device requirements.
• Package and Mounting 1760-FCBGA (42.5 × 42.5 mm) surface-mount package for high-pin-count board-level integration.
• Operating Conditions Industrial operating temperature range from −40 °C to 100 °C for deployment in demanding environments.
• Compliance RoHS compliant to support regulatory and environmental requirements.
• Stratix IV E Family Features Documented family-level features include architecture optimizations, embedded memory, DSP blocks, PLLs and high-speed I/O capabilities as described in the Stratix IV device handbook.

Typical Applications

• High-density digital processing — Implements large custom logic blocks, protocol engines and data-paths that require hundreds of thousands of logic elements.
• Networking and communications — Supports systems that need broad parallel I/O and significant on-chip buffering for packet processing and interface bridging.
• Signal processing and compute acceleration — Provides embedded memory and logic capacity suitable for DSP workloads and hardware-accelerated algorithms.
• Industrial control and automation — Industrial temperature rating and extensive I/O make it suitable for complex machine control, supervisory logic and sensor aggregation.

Unique Advantages

• High logic capacity: 813,050 logic elements enable integration of complex functions and consolidation of multiple subsystems into a single device.
