Key Features

• Core Logic — 531,200 logic elements provide extensive programmable fabric for complex control, processing and glue-logic functions.
• Embedded Memory — Total on-chip RAM of approximately 28 Mbits to implement FIFOs, buffers and memory-intensive algorithms.
• High‑Speed Transceivers — Stratix IV GT family support for up to 48 full‑duplex CDR-based transceivers with data rates up to 11.3 Gbps, enabling multi-gigabit serial protocols and high-speed link implementations.
• DSP Capability — Family-level high-speed DSP blocks configurable as 18 × 18‑bit multipliers for signal processing and arithmetic-intensive tasks.
• I/O Density — 654 user I/Os to accommodate wide parallel interfaces and mixed serial/peripheral connectivity.
• Power Supply — Specified core voltage range from 920 mV to 980 mV for regulated power delivery and margin planning.
• Package — 1517‑BBGA FCBGA package (supplier device package: 1517‑HBGA, 42.5 × 42.5 mm) for high pin-count, board-level integration.
• Temperature Range — Industrial operating temperature from −40 °C to 100 °C for deployment in temperature‑challenging environments.
• Regulatory — RoHS compliant.
• Design Ecosystem — Stratix IV device family is supported by the Quartus® II software toolchain for device design and implementation workflows.

Typical Applications

• High‑Speed Serial Communications — Implement multi‑lane, multi‑protocol links (PCIe, 10 Gb+ Ethernet lanes, Serial RapidIO) using the device’s CDR-based transceivers and configurable PHY features.
• Network Infrastructure — Use the large logic and memory resources for packet processing, traffic management and protocol bridging in switches, routers and line cards.
• Broadcast and Video Processing — Support SD/HD/3G‑SDI and related video transport protocols with high-bandwidth serial connectivity and DSP resources.
• High‑Performance DSP and Acceleration — Deploy DSP blocks and abundant logic to accelerate signal processing, filtering and custom arithmetic pipelines.

Unique Advantages

• Large, Programmable Fabric: 531,200 logic elements enable consolidation of complex system functions into a single device, reducing board-level BOM and interconnect complexity.
• Integrated High‑Speed SerDes: Up to 48 full‑duplex transceivers at multi‑gigabit rates simplify implementation of high-bandwidth links and standardized serial protocols.
• Substantial On‑Chip Memory: Approximately 28 Mbits of embedded RAM supports deep buffering, packet queues and local data storage without external memory.
• Industrial Temperature Rating: −40 °C to 100 °C operation supports deployment in a wide range of environmental conditions.
• High I/O Count: 654 I/Os enable broad connectivity for mixed parallel and serial interfaces on a single FPGA.
• Design Tool Support: Compatibility with the Quartus II software platform streamlines synthesis, place-and-route and timing closure workflows.
