EP4SGX360FH29I3G

The EP4SGX360FH29I3G is an Intel FPGA device drawn from the Stratix IV family, offering a high-density programmable fabric for demanding embedded and industrial applications. It combines a large pool of logic elements and embedded memory with advanced architecture features described in the Stratix IV device handbook.

This device targets designs that require significant logic capacity, substantial on-chip memory, and flexible I/O in a surface-mount FCBGA package—suitable for industrial environments that require extended temperature operation and RoHS compliance.

Key Features

• Logic Capacity  Approximately 353,600 logic elements for implementing large-scale custom logic, state machines, and glue logic.
• Embedded Memory  Approximately 23.1 Mbits of on-chip RAM to support buffering, frame storage, and intermediate data processing without immediate external memory dependency.
• I/O Density  289 user I/O pins provide broad connectivity for external peripherals, memory interfaces, and board-level signaling.
• Package and Mounting  780-ball FCBGA package (supplier device package: 780-HBGA 33×33) in a surface-mount form factor for high-density board integration.
• Core Power  Low-voltage core supply range of 870 mV to 930 mV to match system power architectures that use sub-1V core rails.
• Industrial Temperature Rating  Rated for operation from −40 °C to 100 °C, aligning with industrial-grade deployment needs.
• Architecture Features (Stratix IV)  Device handbook coverage includes high-speed transceiver features, DSP blocks, PLLs, clock networks, and external memory interface support—enabling high-bandwidth and timing-flexible designs.
• Regulatory  RoHS-compliant material status suitable for environmentally regulated product flows.

Typical Applications

• High-speed communications  Implement protocol-specific logic, packet processing, and interface bridging using the device family’s high-speed I/O and architecture capabilities.
• Signal processing and DSP  Leverage abundant logic and on-chip RAM to implement filtering, transforms, and real-time streaming pipelines.
• Industrial control and automation  Use the industrial temperature range and flexible I/O to integrate motor control, sensor aggregation, and deterministic control logic.
• Memory interface and system integration  Serve as a central FPGA for external memory controllers, bus bridging, and board-level glue logic requiring substantial on-chip resources.

Unique Advantages

• High logic density: Approximately 353,600 logic elements allow consolidation of complex functions into a single device, reducing BOM and board area.
• Significant embedded memory: Approximately 23.1 Mbits of on-chip RAM enables larger on-chip buffers and lowers reliance on external memory for many use cases.
• Robust industrial operating range: −40 °C to 100 °C rating supports deployment in harsh or temperature-variable environments.
• Flexible I/O and package: 289 I/Os in a 780-ball FCBGA package support dense external connectivity while fitting high-density PCB designs.
• Low-voltage core operation: 870–930 mV supply range aligns with modern low-voltage power domains to optimize system power design.
• Documented architecture: Backed by the Stratix IV device handbook that details transceiver, DSP, clocking, and memory-interface features for design integration.
