EP4SGX180KF40C4N

The EP4SGX180KF40C4N is a Stratix® IV GX Field Programmable Gate Array (FPGA) IC from Intel, offering a high-density programmable fabric with extensive I/O and on-chip memory. It is designed for applications requiring large logic capacity, significant embedded memory, and advanced I/O and transceiver capabilities as described in the Stratix IV device handbook.

This device combines a high count of logic elements with approximately 14 Mbits of embedded memory and 744 user I/Os, making it suitable for designs that demand heavy logic integration, complex signal processing, or wide-interface connectivity while operating within commercial temperature and low-voltage core ranges.

Key Features

• Core Logic Density — 175,750 logic elements provide a large programmable fabric for complex custom logic and system integration.
• Embedded Memory — Approximately 14 Mbits of on-chip RAM to support buffering, FIFOs, and local data storage for compute and interface tasks.
• High I/O Count — 744 user I/Os to support rich peripheral and external-memory interfacing requirements.
• Stratix IV GX Architecture — Device family features highlighted in the datasheet such as high-speed transceiver support, DSP blocks, PLLs, and robust clock networks for high-bandwidth and timing-sensitive designs.
• Package & Mounting — 1517-BBGA FCBGA package (supplier device package: 1517-FBGA 40×40) in a surface-mount form factor suitable for dense board-level integration.
• Power and Operating Range — Low-voltage core operation with a supply range of 870 mV to 930 mV and a commercial operating temperature range of 0 °C to 85 °C.
• Regulatory — RoHS-compliant construction.

Typical Applications

• High-speed serial interfaces — Leverages Stratix IV GX high-speed transceiver features for protocol bridging and multi-gigabit data paths.
• Signal processing and DSP — On-chip memory and DSP-oriented architecture support filtering, aggregation, and other real-time processing tasks.
• External memory controllers — Large I/O count and dedicated interface features enable custom external memory interfacing and controller implementations.
• I/O-heavy system glue logic — High pin count accommodates complex board-level routing, protocol conversion, and peripheral aggregation.

Unique Advantages

• High logic capacity: 175,750 logic elements enable implementation of large-scale custom logic and soft processors without external ASICs.
• Substantial embedded RAM: Approximately 14 Mbits of on-chip memory reduces reliance on external SRAM/DRAM for many buffering and storage needs.
• Extensive I/O flexibility: 744 user I/Os give designers room to connect multiple interfaces and peripherals directly to the FPGA.
• Advanced I/O and transceiver support: Stratix IV GX architecture includes high-speed transceiver and clocking features described in the device handbook, supporting demanding serial and timing applications.
• Compact integration: 1517-BBGA (1517-FBGA 40×40) surface-mount package enables high-density PCB layouts while preserving thermal and signal routing options.
• Commercial temperature and RoHS compliance: Rated for 0 °C to 85 °C and RoHS compliant for mainstream commercial deployments.
