EP4SGX360NF45I3N Overview

The Intel (formerly Altera) EP4SGX360NF45I3N is a high-density Stratix IV GX Field Programmable Gate Array built on TSMC's 40 nm process, integrating 353,600 logic elements, 23,105,536 bits of embedded memory, and 920 user I/Os in a 1932-ball FC-BGA package. The 'I3' speed grade and 'N' suffix denote the industrial temperature range (-40C to +100C) and lead-free RoHS-compliant assembly, while the 'F45' package designation defines the 45 mm flip-chip BGA with 1.0 mm ball pitch.

An FPGA (Field Programmable Gate Array) is a reprogrammable logic device containing configurable logic blocks, programmable interconnect, and dedicated hard IP such as transceivers, block RAM, and DSP blocks. Stratix IV GX parts sit in the high-end FPGA taxonomy: FPGA -> programmable logic -> logic IC -> integrated circuit -> semiconductor, optimized for system bandwidth and signal integrity in wireline, wireless, and high-speed serial applications.

The EP4SGX360NF45I3N delivers up to 8.5 Gbps transceiver operation through its integrated GX transceivers, supporting protocols such as PCIe Gen1/Gen2, Serial RapidIO, XAUI, CEI-6G, and CPRI. With 14,144 adaptive logic modules (ALMs), 17.7 Mbits of MLAB memory, and Programmable Power Technology, this device targets high-performance systems requiring both massive parallelism and low static power consumption. Each transceiver channel consumes typically 200 mW at 6.5 Gbps, enabling high-density multi-channel line cards.

Architecturally, the EP4SGX360NF45I3N combines a sea-of-ALM fabric with dedicated memory blocks, DSP blocks, PLLs, and PCIe hard IP, allowing designers to instantiate complex multi-gigabit serial interfaces without consuming soft logic. The 40 nm process delivers roughly 35% lower dynamic power than the prior 65 nm Stratix III generation, while Programmable Power Technology allows unused logic to operate at near-zero static current.

Typical applications include high-end wireline networking line cards (40G/100G OTN), wireless baseband processing, military radar and electronic-warfare systems, and broadcast video infrastructure. The 1932-ball FC-BGA package supports the high pin density required for parallel memory interfaces (DDR3/QDRII+) and multiple multi-gigabit transceivers simultaneously.

When designing with this device, plan power architecture for the 0.9 V core rail and the 1.1 V/1.5 V/1.8 V/2.5 V/3.0 V I/O rails using the PowerPlay Early Power Estimator. Use controlled-impedance routing for all transceiver channels and follow the Stratix IV GX pin-out guide for recommended decoupling. Lead time for this NRND-era part should be confirmed via franchised distributors.

This page synthesizes real-time distributor pricing, package-compatible same-family alternatives, and Stratix IV GX-specific design notes that go beyond what the manufacturer datasheet alone provides, including cross-references to other 360K-LE Stratix IV devices in the same NF45 package.

Selection Guide

Choose EP4SGX360NF45I3N for new industrial-temperature designs targeting 8.5 Gbps multi-gigabit transceivers in the 1932-ball F45 BGA footprint, where high logic density (353K LE) and 23 Mbit embedded memory are required. Choose EP4SGX290NF45I3N if the design fits 291K LE (-18%) and you want cost savings at the same F45 footprint. Choose EP4SGX360NF45C3N for indoor commercial-temperature (0C to +85C) variants. Avoid the KF43 package variants (EP4SGX360KF43I3N) unless your PCB is redesigned for the 1517-ball BGA.

Key Differentiators

  • Highest-density F45 BGA in 360K-LE Stratix IV GX family (vs EP4SGX290NF45I3N)
  • Industrial temperature range with same F45 ball-out (vs EP4SGX360NF45C3N)
  • I3 speed grade with F45 NF package suffix for lead-free compliance (vs EP4SGX360NF45I3)
  • Pin-compatible with all F45 360K-LE Stratix IV GX variants (vs EP4SGX360KF43I3N)

Design Notes

Estimated: at 0.9 V core and 353K LE fully utilized, total core current can reach 15-25 A. Use the Intel PowerPlay Early Power Estimator (EPE) tool to size the 0.9 V regulator. Decouple with 0402/0201 ceramics placed immediately adjacent to every ball-grid VCC/GND pair, plus 220 uF bulk capacitors within the BGA shadow. The 1.1 V/1.5 V/1.8 V/2.5 V/3.0 V I/O and PLL auxiliary rails each require independent regulators with their own isolation inductors for multi-gigabit transceiver jitter performance.

Use a high-density PCB stackup with at least 14 layers for the 1932-ball 1.0 mm pitch FC-BGA. Each transceiver channel must route on a single layer over a continuous ground plane with 100 ohm differential impedance; reference the Stratix IV GX High-Speed Board Design Guidelines for via patterns. Escape the BGA using buried vias to maximize routing density. Fanout for memory should follow the DDR3 read/write level-matching rules in the Stratix IV External Memory Interface Handbook.

Estimated: a Stratix IV GX at full 353K-LE utilization can dissipate 15-25 W depending on clock rate and toggle activity. The 45 mm BGA substrate has a theta_JA of approximately 0.5 C/W with a proper heatsink thermal interface material. Without airflow, derate by 50%. Provide a thermal pad contact or heat-spreader plate in the layout footprint, and avoid routing 12 inner layers as solid reference planes directly under hot transceiver lanes.

Do not apply power before all I/O and PLL rails are sequenced - the Stratix IV GX requires the 0.9 V core to ramp last. Mixing C-speed (commercial) and I-speed (industrial) parts on the same PCB causes JTAG IDCODE errors; verify date code per BOM. The 'N' suffix on EP4SGX360NF45I3N indicates lead-free / RoHS; confirm reflow profile matches the 260 C MSL-3 floor-life window if the part is repacked or stored.
