Typical Applications

EP1SGX25CF672I6N is suitable for 6 applications: Multi-Gigabit Serial Interface Bridge, Telecom Line Card / Datacom Switch, Digital Video Broadcast Equipment, ASIC Prototyping, Industrial Control and Factory Automation, Medical Imaging Equipment.

🌐

Multi-Gigabit Serial Interface Bridge

The EP1SGX25CF672I6N's integrated multi-gigabit transceivers and 25,660 logic elements make it ideal for protocol-bridging designs that translate between serial standards such as PCI Express, Serial RapidIO, Gigabit Ethernet, andXAUI on a single board. The 455 user I/Os provide ample parallel-side bandwidth for bridging to local bus interfaces, memory controllers, and high-speed peripherals. Designers typically place the FPGA between a host ASIC and a backplane SERDES, implementing the protocol conversion in RTL with Quartus II. The industrial -40 to +85°C temperature range allows deployment in outdoor telecom cabinets and factory-floor equipment.

📡

Telecom Line Card / Datacom Switch

Telecom line cards and datacom switches require high-density logic with embedded transceivers to handle backplane serialization, packet processing, and fabric interfaces. The EP1SGX25CF672I6N delivers 25,660 LE for packet-classification logic, plus its transceivers support backplane speeds typical of telecom line cards. The 672-ball FCBGA package enables compact line-card layouts where board real-estate is at a premium. The industrial temperature grade supports deployment in central-office equipment with extended thermal envelopes. Power designers should follow the Stratix GX hardware reference manual decoupling scheme for the 1.5 V core and analog supply rails.

📺

Digital Video Broadcast Equipment

Digital video broadcast equipment - including encoders, transcoders, and DVB modulators - benefits from the EP1SGX25CF672I6N's DSP blocks and parallel I/O bandwidth. Designers can implement multi-channel SDI processing, MPEG transport stream parsing, and adaptive filtering inside the FPGA, eliminating the need for a companion DSP processor. The 455 user I/Os support multi-channel parallel video interfaces, while the embedded transceivers handle ASI (asynchronous serial interface) links to upstream modulators. Industrial temperature grade supports outdoor headend enclosures and broadcast tower installations.

🖥️

ASIC Prototyping

ASIC prototyping is one of the most demanding FPGA use cases, requiring high logic density, abundant I/O, and predictable timing closure. The EP1SGX25CF672I6N with 25,660 LE and 455 I/Os can map mid-complexity ASICs with the Quartus II incremental compilation flow, supporting rapid RTL iteration. The 1 mm pitch FBGA exposes a wide I/O bank fan-out that lets designers route real-world ASIC peripherals. The Stratix GX architecture's dedicated transceivers allow prototype validation of ASIC SerDes macros. Engineering teams typically build multi-FPGA prototyping systems using this family and migrate to the next-density Stratix for full ASIC mapping.

🏭

Industrial Control and Factory Automation

Industrial control systems require deterministic logic processing, motor-control interfaces, and fieldbus connectivity - all of which the EP1SGX25CF672I6N can deliver with its 25,660 LE and embedded DSP blocks. Designers can implement EtherCAT, PROFINET, or custom fieldbus MACs alongside motion-control algorithms. The industrial -40 to +85°C temperature range supports deployment in factory-floor cabinets, outdoor enclosures, and process-control rooms. The 455 I/Os provide sufficient fan-in for multi-axis motion-control cards. Designers should verify the device's lifecycle status before committing to long production runs.

💊

The C7N is a faster speed grade, so for timing-critical designs at commercial temperatures, EP1SGX25CF672C7N may meet Fmax where EP1SGX25CF672I6N does not. According to the Altera ordering guide, the speed grade is the second-to-last character before the package code.
What is the best drop-in replacement for EP1SGX25CF672I6N?
The best drop-in replacements for EP1SGX25CF672I6N are EP1SGX25CF672I6 (leaded variant of the same die) and EP1SGX10DF672I6N (lower-density 10K-LE member in the same Stratix GX 672-ball FCBGA). EP1SGX25CF672I6 is pin-to-pin compatible but lacks lead-free compliance. For new designs where drop-in is not required, current-generation Stratix, Cyclone, or Agilex FPGAs are recommended over legacy Stratix GX parts.
Can EP1SGX25CF672C6N replace EP1SGX25CF672I6N?
Yes, EP1SGX25CF672C6N can drop-in replace EP1SGX25CF672I6N on the same 672-ball FCBGA footprint, but only in designs where the commercial 0 °C to +85 °C temperature range is acceptable. According to the Altera datasheet, both parts share the same 25,660 LE, 2,852 CLBs, and 455 I/Os. Designers must verify their system's cold-start spec does not require sub-zero operation before substituting commercial for industrial.

Hey Google, what is the equivalent Intel Stratix FPGA to EP1SGX25CF672I6N?
The closest Intel equivalents to EP1SGX25CF672I6N are EP1SGX25CF672I6 (same die, leaded), EP1SGX25CF672C6N (commercial grade, same die), and EP1SGX10DF672I6N (lower-density 10K-LE member, same 672-ball FCBGA). According to Intel's Stratix GX ordering guide, all three parts share the same 672-ball FCBGA package. The decision between them depends on temperature grade and lead-free requirement, not package compatibility.
Is EP1SGX25CF672I6N the same as EP1SGX25CF672C6N?
No, EP1SGX25CF672I6N and EP1SGX25CF672C6N are not exactly the same - they differ in temperature grade. The 'I' in EP1SGX25CF672I6N denotes industrial (-40 °C to +85 °C), while the 'C' in EP1SGX25CF672C6N denotes commercial (0 °C to +85 °C). According to the Altera ordering guide, both share the same die, package, and 25,660 LE. They are drop-in pin-compatible, but the temperature grade must match the application's cold-start spec.
What are the key specifications of EP1SGX25CF672I6N that engineers should know?
Engineers should know that EP1SGX25CF672I6N is a 25,660-logic-element Stratix GX FPGA with 2,852 CLBs, 2,566 LABs, 455 user I/Os, integrated multi-gigabit transceivers, 1.5 V core supply, and 672-ball FCBGA package (27 x 27 mm, 1 mm pitch). It operates from -40 °C to +85 °C (industrial grade, I6 suffix). According to the Altera datasheet, the part is in last-time-buy lifecycle as of 2026, so engineers must plan for migration to current-generation devices.
What is the best Xilinx equivalent for EP1SGX25CF672I6N?
There is no true pin-compatible Xilinx equivalent for EP1SGX25CF672I6N because the 672-ball FCBGA is an Intel/Altera-specific package. According to cross-brand reference searches, designers targeting multi-gigabit transceivers at the 25K-LE density class can consider Xilinx Virtex-4 FX family in a similar-density BGA package, but a different footprint and different I/O mapping - meaning no PCB drop-in is possible. A full PCB redesign is required to migrate to Xilinx.

Key Differentiators

  • Industrial temperature range with lead-free RoHS compliance (vs EP1SGX25CF672I6 (leaded variant))
  • Highest-density member of the 672-ball FCBGA Stratix GX lineup (vs EP1SGX10DF672I6N (10K-LE lower-density variant))
  • Industrial -40 to +85 C operating range vs commercial 0-85 C (vs EP1SGX25CF672C6N (commercial grade))

Design Notes

The Stratix GX EP1SGX25CF672I6N requires a 1.5 V core supply plus separate analog supplies for PLLs and multi-gigabit transceivers. According to the Stratix GX hardware reference manual, the supply-rail sequencing must follow the Altera-defined power-on sequence to avoid latch-up. Designers should provide at least 1 A of headroom on the 1.5 V core for typical 25K-LE utilization, and additional capacity for transceiver channels when active. Decoupling must follow the Stratix GX reference board layout with 0.1 uF and 0.01 uF capacitors placed close to every supply pin.

Estimated: at full 25,660 LE utilization and active transceiver channels, the EP1SGX25CF672I6N can dissipate 5-8 W. The 27 x 27 mm FCBGA has a theta_JA of approximately 8-12 C/W with sufficient PCB thermal vias. Designers should implement a thermal via array under the exposed pad region of the FCBGA and at least 4 thermal vias per supply/ground ball pair to keep junction temperature within the industrial 85 C limit. Heat-spreader copper pours on inner PCB layers are recommended for high-utilization designs.

The 672-ball FCBGA with 1 mm ball pitch demands a PCB fabrication tolerance of +/- 0.05 mm on the land diameter. Designers must use the Intel/Altera-provided land pattern and follow the Stratix GX hardware reference manual for stackup and via-in-pad recommendations. High-speed transceiver channels require 100 ohm differential impedance with length matching to within the budget specified in the transceiver user guide. Layer stackup must provide reference planes for all high-speed signals to control return-path discontinuities.

Do not assume the EP1SGX25CF672I6N is in active production - according to the verified web data, this part is in last-time-buy lifecycle. Designers committing to production BOMs must plan for migration to a current-generation Stratix or Agilex device before supply is depleted. Also, do not confuse the EP1SGX25CF672I6N (industrial, lead-free) with EP1SGX25CF672I6 (industrial, leaded) - the leaded variant will fail RoHS compliance audits in markets requiring lead-free assemblies.
