The EP4SGX290NF45C3G is an Intel (Altera) Stratix IV family FPGA device designed for advanced system integration. It provides a large logic fabric and substantial on-chip memory within a high-density FCBGA package, suitable for complex digital designs.

Documented in the Stratix IV device handbook, the device targets applications that require extensive logic resources, abundant I/O, and support for on-chip memory and high-speed subsystem features described in the family handbook.

Key Features

• Logic Capacity — 291,200 logic elements to implement large-scale digital logic and customized processing pipelines.
• Embedded Memory — Approximately 17.7 Mbits of on-chip RAM for buffers, FIFOs, and local data storage within the FPGA fabric.
• I/O Count — 920 general-purpose I/O pins to support dense board-level connectivity and multiple peripheral interfaces.
• Stratix IV Architecture — Device references in the Stratix IV Device Handbook show architecture features such as DSP blocks, PLLs, clock networks, external memory interfaces, and high-speed transceiver capabilities.
• Package and Mounting — 1932-ball FCBGA (45 × 45) in a surface-mount package for high-density PCB integration.
• Core Voltage Range — Core supply specified at 870 mV to 930 mV (0.87–0.93 V) to support the device’s internal logic domains.
• Commercial Temperature Grade — Rated for 0 °C to 85 °C operation, suitable for commercial-class electronic systems.
• RoHS Compliant — Meets RoHS environmental requirements for lead-free assembly and manufacturing.

Typical Applications

• High-speed serial communications — Use with the Stratix IV transceiver and protocol support described in the device handbook to implement serial link endpoints and protocol bridges.
• Digital signal processing — Deploy DSP blocks and abundant logic and memory for signal filtering, encoding/decoding, and real-time data manipulation.
• External memory controllers — Implement complex memory interfaces and controllers leveraging the family’s external memory interface features.
• System integration and prototyping — Large logic capacity and extensive I/O make it suitable for consolidating multiple functions onto a single programmable device during development or in production systems.

Unique Advantages

• High logic density: 291,200 logic elements enable complex, consolidated designs and multi-function integration on a single device.
• Substantial on-chip memory: Approximately 17.7 Mbits of embedded RAM reduce external memory requirements for many buffering and storage needs.
• Extensive I/O resources: 920 I/O pins support dense peripheral interfaces and flexible board-level connectivity without immediate need for external expanders.
• Compact, high-density package: 1932-ball FCBGA (45×45) allows a high-pin-count implementation while minimizing PCB footprint.
• Architecture-level features: Device falls under Stratix IV family documentation that describes DSP blocks, clock networks, PLLs, and high-speed transceiver support—useful for system-level integration decisions.
• Regulatory and assembly readiness: RoHS compliance and surface-mount package make the device suitable for modern lead-free production workflows.
