• I/O and Transceivers — 488 I/O pins and Stratix IV GX high-speed transceiver features, suitable for designs requiring high aggregate data bandwidth and support for multiple serial protocols.
• Package & Mounting — 1152-FBGA (35 × 35 mm) FCBGA package, surface-mount for compact board-level integration.
• Power — Core voltage supply specified at 870 mV to 930 mV to match system power domains and enable predictable power planning.
• Operating Conditions — Commercial grade operation with an ambient temperature range of 0 °C to 85 °C.
• Compliance — RoHS-compliant for environmental and regulatory considerations.
• Documentation — Part of the Stratix IV family with detailed device handbook and device-level documentation for architecture, transceivers, memory and I/O features.

Typical Applications

• High-Bandwidth Communications — Implements protocol bridging, packet processing and line-side interfaces that require high aggregate data throughput and high-speed serial transceivers.
• Data-Path Acceleration — On-chip logic and embedded RAM support buffering and processing tasks for networking and compute acceleration.
• Signal Processing — Combines dense logic and embedded memory for DSP-oriented pipelines and real-time data manipulation.
• System Integration — Provides large I/O count and flexible I/O standards for consolidating multiple interfaces and peripherals on a single FPGA.

Unique Advantages

• High Logic Capacity: 72,600 logic elements enable complex system functions and large-scale designs without external ASICs.
• Significant On-Chip Memory: Approximately 7.56 Mbits of embedded RAM reduces reliance on external memory for many buffering and temporary storage needs.
