It delivers large logic capacity and substantial embedded memory, combined with the Stratix IV family architecture that includes high‑speed transceiver and I/O features.

This device is intended for designs that require significant on‑chip logic, extensive I/O, and integrated memory resources—where integration and architectural features of the Stratix IV series are needed to implement complex digital systems.

Key Features

• High logic capacity — 291,200 logic elements to implement large-scale digital logic and complex custom architectures.
• Embedded memory — Approximately 17.66 Mbits of on‑chip RAM for buffering, frame storage, and local data handling.
• Extensive I/O — 564 I/O pins to support wide parallel interfaces and multiple peripheral connections.
• Stratix IV GX architecture — Includes Stratix IV series features such as high‑speed transceiver support, DSP blocks, PLLs, and advanced clock networks as described in the device handbook.
• Package and mounting — 1152‑BBGA (1152‑FBGA, 35×35 supplier package) in a surface‑mount FCBGA form factor for compact board integration.
• Core supply range — Operates with a core voltage supply between 870 mV and 930 mV.
• Commercial grade operating range — Specified for 0 °C to 85 °C operation and classified as commercial grade.
• RoHS compliant — Conforms to RoHS requirements for lead‑free assembly.

Typical Applications

• High‑speed communications — Implement protocol engines and data path logic leveraging Stratix IV GX transceiver and I/O features.
• Digital signal processing — Use the device’s large logic array and embedded memory for DSP pipelines and algorithm acceleration.
• Memory interface controllers — Integrate external memory controllers and wide interface logic using abundant I/O and on‑chip RAM.

Unique Advantages

• Large on‑chip logic resource: 291,200 logic elements reduce the need for external glue logic and enable complex SoC‑style implementations.
