EP4SGX290FF35I4G

The EP4SGX290FF35I4G is an Intel FPGA from the Stratix IV family, designed for high-density programmable logic integration. It combines a large logic fabric with embedded memory and advanced I/O capability in a surface-mount FCBGA package for industrial applications.

This device targets systems that require substantial on-chip logic and memory capacity, broad I/O counts, and operation across an industrial temperature range. Key value comes from the Stratix IV architecture elements cited in the device documentation, including embedded memory, DSP blocks, PLLs, and high-speed transceiver features.

Key Features

• Logic Capacity — 291,200 logic elements to implement large FPGA designs and complex control or data-processing functions.
• Embedded Memory — Total on-chip RAM of 17,661,952 bits, approximately 17.66 Mbits of embedded memory for buffering, FIFOs, and local storage.
• I/O and Connectivity — 564 user I/O pins to support wide external interfacing and parallel/serial connections.
• Stratix IV Architecture Features — Device documentation references Stratix IV capabilities including embedded memory, DSP blocks, PLLs, high-speed transceivers, clock networks, and external memory interface support.
• Package and Mounting — 1152-pin FCBGA / FBGA (1152-FBGA, 35×35) surface-mount package to accommodate high pin counts and dense board integration.
• Power — Specified core voltage supply range of 870 mV to 930 mV for the device core.
• Industrial Temperature Range — Rated for operation from −40 °C to 100 °C, appropriate for industrial environments.
• Compliance — RoHS compliant.

Typical Applications

• High-speed communications — Use of the Stratix IV transceiver and I/O features for protocol bridging, link aggregation, and serial data transport.
• External memory interfaces — Implementing controllers and interfaces that require tight integration between programmable logic and external memory subsystems.
• Signal processing and DSP acceleration — Leveraging the device’s large logic element count and documented DSP blocks for real-time data processing and filtering tasks.
• Industrial control systems — Deploying high-density programmable logic in industrial environments where the −40 °C to 100 °C operating range and surface-mount FCBGA packaging are required.

Unique Advantages

• High logic density: 291,200 logic elements provide capacity for complex state machines, datapaths, and integration of multiple functions on a single device.
• Substantial on-chip RAM: Approximately 17.66 Mbits of embedded memory reduces the need for external buffering and supports intensive local data handling.
• Extensive I/O: 564 I/O pins enable flexible system interfacing and support for multiple external peripherals or high-bandwidth parallel buses.
• Stratix IV feature set: Architecture elements called out in the device handbook—such as DSP blocks, PLLs, clock networks, and high-speed transceivers—help implement timing-critical and high-throughput designs.
• Industrial robustness: Specified operating range from −40 °C to 100 °C and RoHS compliance support deployment in industrial-grade applications.
• High-pin-count packaging: 1152-pin FCBGA/FBGA (35×35) supports dense board integration and routing for complex systems.
