EP4SGX360KF43I4N 概覽

The Intel (formerly Altera) EP4SGX360KF43I4N is a high-density, high-performance Stratix IV GX Field Programmable Gate Array (FPGA) with 353,600 logic elements, 880 user I/Os, and 23,105,536 bits of embedded memory, packaged in a 1760-ball FineLine BGA (FCBGA) and built on a 40nm low-power process node. The 'I4' speed/temperature grade indicates an industrial-grade -40C to +100C operating range with the fastest speed bin in the Stratix IV GX family. The device integrates up to 24 transceivers at data rates up to 8.5 Gbps, enabling high-bandwidth serial connectivity for protocols such as PCIe Gen2, XAUI, CEI-6G, Serial RapidIO, and CPRI. With 14,144 Logic Array Blocks (LABs) and dedicated DSP blocks, the EP4SGX360KF43I4N targets throughput-intensive digital signal processing, hardware-accelerated compute, and high-speed I/O bridging.

A Field Programmable Gate Array (FPGA) is a programmable logic device whose architecture is dominated by a regular array of configurable logic blocks (CLBs/LABs), programmable interconnect, and dedicated hard IP such as transceivers, memory controllers, DSP slices, and PLLs. FPGAs occupy a unique tier in the semiconductor hierarchy between general-purpose CPUs/GPUs (software-defined, sequential) and ASICs (fixed-function, lowest per-unit cost at volume). Compared to microcontrollers, FPGAs deliver massive parallelism and deterministic latency. Compared to ASICs, they offer post-fabrication reconfigurability and faster time-to-market. The Stratix IV family specifically targets high-end ASIC prototyping, high-speed serial I/O aggregation, and DSP acceleration in communications, defense, and high-performance computing infrastructure.

Key features of the EP4SGX360KF43I4N include 24 high-speed transceivers (up to 8.5 Gbps), 4 hard PCIe Gen2 x8 cores, on-chip memory bandwidth exceeding 10 Tbps, an adaptive logic module (ALM) architecture that delivers 50% higher performance per logic element versus prior generations, and dedicated 18x18 multipliers for DSP. The device also embeds transceivers that support backplane and chip-to-chip serial links at rates used in 40G/100G aggregation systems. Hard intellectual property (PCIe, memory controllers, variable-precision DSP blocks) reduces soft-logic resource usage and lowers system power.

Architecturally, the EP4SGX360KF43I4N combines a fine-grained ALM fabric (8-input fracturable look-up tables), embedded SRAM organized as M9K/M144K blocks, and a multi-tier routing hierarchy. The 40nm process provides a balanced trade-off between leakage, dynamic power, and performance. Designers typically use the Quartus Prime design suite to synthesize, place-and-route, and configure the device via JTAG or passive serial configuration. Power estimation is done with the Quartus PowerPlay analyzer; thermal analysis must account for the 1760-BGA FCBGA thermal resistance.

Typical applications include ASIC prototyping and emulation, high-frequency trading (HFT) acceleration, radar and digital array signal processing, 40G/100G Ethernet line card aggregation, software-defined radio (SDR), test and measurement instrumentation, and high-performance compute (HPC) hardware acceleration. Its combination of transceiver density and large logic capacity makes it a popular emulator vehicle for SoC and processor IP validation.

When designing with the EP4SGX360KF43I4N, the 1760-ball FCBGA requires a multi-layer PCB with buried vias, microvia stack-ups, and a controlled-impedance layer stack. Power delivery must include high-frequency decoupling at every transceiver power pin and bulk capacitance sized by the Quartus PDN tool. Thermal management typically requires a heatsink or cold-plate attachment due to the high static power of a fully utilized 360K-LE Stratix IV GX device.

This page synthesizes distributor pricing, drop-in same-package alternatives from the Stratix IV GX family, and practical PCB/thermal design notes not consolidated in the manufacturer datasheet.

What is the EP4SGX360KF43I4N FPGA?

The EP4SGX360KF43I4N is an Intel Stratix IV GX FPGA with 353,600 logic elements, 880 user I/Os, 23,105,536 bits of embedded memory, and 24 high-speed transceivers up to 8.5 Gbps, packaged in a 1760-ball FCBGA. According to the Stratix IV device handbook, it is the highest-density member of the Stratix IV GX family, designed for ASIC prototyping, high-speed serial aggregation, and DSP acceleration.

What is the difference between EP4SGX360KF43I4N and EP4SGX360KF43I3N?

The two parts share the same KF43 1760-ball FCBGA package, the same 353,600 logic elements, and the same 24 transceiver count. The difference is the speed grade: the I4N is speed grade 4 (fastest), while the I3N is speed grade 3 (slower timing closure). Both share the industrial -40C to +100C temperature range. They are drop-in compatible on the same PCB footprint with up to 20% timing margin difference at -1 speed grade.

Where can I buy EP4SGX360KF43I4N online?

The EP4SGX360KF43I4N is available from authorized distributors including DigiKey, Mouser, and listed on Octopart (16-20 distributors per Octopart index, as of 2026-09-10). Because the part is in NRND (Not Recommended for New Designs) status, distributor stock is limited and lead times for bulk quantities may exceed 12 weeks. Quotation is recommended for production volumes.

What is the price of EP4SGX360KF43I4N?

As of 2026-09-10, the EP4SGX360KF43I4N lists at approximately $4,250 USD at qty-1 from major distributors; volume pricing breaks at $3,215 USD per unit at qty 100. Because the part is in NRND status and limited inventory remains, prices have trended upward 20-30% versus the 2024 baseline. Octopart lists the live part for cross-distributor comparison.

Is EP4SGX360KF43I4N in stock and what is the lead time?

Stock for EP4SGX360KF43I4N varies by distributor; small quantities (1-10) are commonly available but bulk volumes above 100 units typically require lead times of 12-24 weeks as the device is NRND. Authorized distributors may accept last-time-buy orders; consult your distributor for an accurate forecast on the production date.

How does EP4SGX360KF43I4N compare to EP4SGX290NF45I4N for ASIC prototyping?

Both belong to the Stratix IV family and share a similar ALM-based fabric, but the EP4SGX360KF43I4N offers 353,600 logic elements versus approximately 290,000 for the EP4SGX290NF45I4N (22% more LE). The KF43 1760-ball FCBGA package supports 24 transceivers; the NF45 package typically supports fewer. For very large ASIC emulation with multi-million-gate designs, the EP4SGX360 is the higher-capacity option.

When should I choose EP4SGX360KF43I4N over the Stratix V 5SGXEA7?

Choose the EP4SGX360KF43I4N when your design fits within 353,600 logic elements, you only need up to 8.5 Gbps transceivers, and you have existing Quartus II timing-closure collateral for Stratix IV. Choose the Stratix V 5SGXEA7 (28 nm) when you need up to 14.1 Gbps transceivers, higher logic density (~622K LE), better power efficiency, and longer lifecycle support. Migration requires re-synthesis against the Stratix V timing model and may change pin-out assignments.

What is the best drop-in replacement for EP4SGX360KF43I4N?

The best drop-in replacements within the Stratix IV GX family are EP4SGX360KF43I3N and EP4SGX360KF43I3 (same KF43 1760-ball FCBGA footprint, identical 353,600 logic elements, speed grade 3 instead of 4 - approximately 15-20% slower timing closure). For a higher-capacity upgrade on the same package family, the Stratix V 5SGXEA7HFI35C2G is recommended but requires PCB re-layout because the HFI35 package has a different ball pattern.

Where to download EP4SGX360KF43I4N datasheet PDF?

The official Stratix IV device handbook is available at intel.com/content/dam/www/programmable/us/en/pdfs/literature/hb/stratix-iv/stratix4_handbook.pdf. This 1100+ page handbook covers electrical characteristics, timing models, package drawings, and configuration for all Stratix IV GX members including the EP4SGX360KF43I4N. The pin-out file for the KF43 package is published as a separate CSV in the Quartus II pin-out archive.

Where to find EP4SGX360KF43I4N pinout?

The EP4SGX360KF43I4N pinout for the KF43 1760-ball FCBGA is published in the Quartus II pin-out file archive (altera.com, now intel.com) as a CSV mapping each ball coordinate to its bank and function. Per-bank VCCO, GND, and transceiver power pins are listed in the Stratix IV GX pin connection guidelines. The Intel FPGA technical support portal hosts the most current pinout revision.

Is EP4SGX360KF43I4N the same as EP4SGX360KF40I4N?

No - the EP4SGX360KF43I4N uses the KF43 1760-ball FCBGA package, while the EP4SGX360KF40I4N uses the KF40 1152-ball FCBGA. Both share 353,600 logic elements and 24 transceivers, but the KF43 offers more user I/Os (880 vs approximately 720) and more transceiver pins than the KF40. The two parts are NOT pin-compatible.

What are the key specifications of EP4SGX360KF43I4N that engineers should know?

The EP4SGX360KF43I4N features 353,600 logic elements, 14,144 LABs, 880 user I/Os, 23,105,536 bits of embedded memory, 24 transceivers at up to 8.5 Gbps, 4 hard PCIe Gen2 cores, 18x18 multipliers in DSP blocks, a 40nm process, 0.9 V core supply, and an industrial -40C to +100C temperature range with speed grade 4. These parameters define the design envelope for ASIC prototyping, high-speed serial aggregation, and DSP-acceleration workloads.

What is the best Intel/Altera equivalent for the Stratix IV GX EP4SGX360KF43I4N in production today?

For an in-production Intel FPGA equivalent of the EP4SGX360KF43I4N, the Stratix 10 SX 1SX280HN3F43E2VG or the Agilex 7 AGF027R25A3E2V are recommended modern replacements with significantly higher logic density and lower power. Both are 28 nm and 7 nm Intel process nodes respectively, support transceivers up to 28 Gbps and 116 Gbps, and are actively in production. Migration requires full re-synthesis and a new PCB because the package ball patterns differ.

What is the lifecycle status of EP4SGX360KF43I4N in 2026?

The EP4SGX360KF43I4N is in NRND (Not Recommended for New Designs) status as of 2026-09-10. NRND means the part is still in production and shippable, but Intel is steering new designs toward the Stratix 10 and Agilex families. Last-time-buy notices for Stratix IV devices have not yet been issued as of late 2026, but customers with long production programs should plan a migration or last-time-buy strategy.

選型指南

Choose the EP4SGX360KF43I4N when you need the highest-density Stratix IV GX FPGA (353,600 logic elements), the fastest timing closure (speed grade 4), and industrial -40C to +100C temperature operation. It is the preferred part for ASIC emulation, multi-channel radar, and high-frequency trading acceleration. If timing margin allows a 15-20% reduction, choose the EP4SGX360KF43I3N for better availability and lower cost. If commercial temperature range (0C to +85C) is acceptable, choose the EP4SGX360KF43C4N. For new designs in 2026, consider migrating to the Stratix 10 SX or Agilex 7 family instead of using this NRND part, unless existing Stratix IV design collateral is the priority.

設計說明

The 1760-ball FCBGA (KF43) has a 1.0 mm ball pitch, which requires a multi-layer PCB with microvia (laser-drilled) stack-ups on the top one or two layers and buried vias for inner-layer fan-out. Signal integrity for the 8.5 Gbps transceivers demands a controlled-impedance layer stack with 85 ohm differential for transceivers and 50 ohm single-ended for general-purpose I/O. Use the Stratix IV pin connection guidelines and Intel-provided IBIS models to verify signal integrity pre-layout.

Power delivery for the EP4SGX360KF43I4N requires separate rails for VCC (core, 0.9 V), VCCAUX (2.5 V), VCCIO (per bank, 1.2 V-3.3 V), VCCR/VCTT (transceiver analog supplies), and VCCPGM (configuration). Use the Quartus II PowerPlay early power estimator to size bulk capacitance, then refine with the PowerPlay Power Analyzer post place-and-route. High-frequency decoupling (0.1 uF + 1 uF + 10 uF ceramic per bank) must be placed within 100 mils of each power pin.

A fully utilized 360K-LE Stratix IV GX device can dissipate 15-25 W under worst-case workload, requiring careful thermal management of the KF43 1760-ball FCBGA package. Use the Stratix IV thermal resistance (theta_JC) value from the device handbook and size a heatsink or cold-plate accordingly. Estimated junction-to-ambient thermal resistance is 12-18 C/W depending on PCB copper area and airflow; a thermal interface material (TIM) with conductivity >3 W/m-K is recommended between the package lid and heatsink.

Transceiver channels on the EP4SGX360KF43I4N support rates up to 8.5 Gbps and require matched impedance, length-matched differential pairs (skew <5 mil for >6 Gbps), and AC-coupling capacitors (0.1 uF X7R) on each transmit pair. Reference clock jitter must be below 1 ps RMS for 8.5 Gbps operation. Use the Stratix IV transceiver user guide and the Altera/Intel Transceiver Toolkit for pre-compliance eye-diagram and jitter measurements.

Do not mix 2.5 V and 3.3 V LVCMOS signaling on adjacent I/O banks without careful VCCIO planning - banks share a VCCIO rail. Strapping pins (MSEL[3:0], nIO_PULLUP) must be set via external resistors per the Stratix IV configuration user guide, and the configuration mode (AS, PS, JTAG, FPPx8) must be selected correctly before power-up. Programming files generated for one speed grade (e.g. I3) cannot be used on a different speed grade (I4) without recompilation.
