Designed for demanding industrial applications, this device targets designs that require high logic capacity, substantial embedded memory, and extensive I/O connectivity while operating across a wide industrial temperature range.

Key Features

• Core Capacity — 175,750 logic elements and 7,030 CLBs provide substantial programmable logic resources for complex designs.
• Embedded Memory — Approximately 13.95 Mbits of on-chip RAM to support buffering, packet processing, and local data storage.
• I/O Density — 564 I/O pins to accommodate wide external interfacing, multi-channel connectivity, and parallel buses.
• Stratix IV GX Series Features — Series-level architecture includes high-speed transceiver support, DSP blocks, PLLs, clock networks, and external memory interface capabilities as described in the Stratix IV device handbook.
• Package and Mounting — 1152‑FBGA (35×35) package in a surface-mount form factor (listed as 1152-BBGA, FCBGA) for high‑density board implementations.
• Power — Core supply range specified from 870 mV to 930 mV.
• Industrial Temperature Range — Rated for operation from −40 °C to 100 °C for industrial environments.
• Compliance — RoHS compliant.

Typical Applications

• High-speed serial and protocol bridging — Leverages Stratix IV GX transceiver features for designs that require protocol conversion and serial link aggregation.
• Signal processing and DSP — Large logic capacity and embedded memory support DSP pipelines and real-time data processing tasks.
• Memory interface controllers — On‑chip resources and external memory interface features enable memory controller and caching functions.
• I/O‑intensive systems — High I/O count supports multi-port interfaces, wide parallel buses, and rich peripheral connectivity.

Unique Advantages

• Large programmable fabric: 175,750 logic elements give room for complex algorithms, custom accelerators, and wide datapaths.
• Significant embedded memory: Approximately 13.95 Mbits of on‑chip RAM reduces external memory dependence for intermediate buffering and local storage.
• High I/O capacity: 564 I/Os enable extensive external interfacing and system partitioning without additional IO expanders.
• Designed for high-speed serial designs: Stratix IV GX series-level transceiver and protocol support (as documented in the device handbook) facilitate high-bandwidth connectivity.
• Industrial grade thermal range: −40 °C to 100 °C operation supports deployment in demanding environmental conditions.
• Compact, high-density package: 1152‑FBGA (35×35) surface-mount packaging offers a small footprint for high-performance boards.
