Lead time for the EP1S25F780I6N at Heisener is listed as 'To Be Confirmed' with estimated delivery of approximately Jun 27 - Jul 2 (a 1-2 week window) as of 2026-09-07. For obsolete/legacy FPGAs, lead times can vary significantly between distributors. Expedited shipping is offered; for production orders, locking in allocation with the supplier in advance is recommended.
What is the best drop-in replacement for EP1S25F780I6N?
The best drop-in replacement for EP1S25F780I6N within the same Stratix family is EP1S25F780C6N (commercial temperature grade, same 780-BBGA package, same 25,660 logic elements). Within the same die/pinout, EP1S25F780C5N and EP1S25F780C7N are also compatible variants differing only in speed grade. For modern designs, migrate to Cyclone IV E (EP4CE22/30) or Cyclone 10 LP; pin-out and footprint will differ, requiring PCB rework.
EP1S25F780I6N vs EP1S25F780C6N - which is better for industrial design?
For industrial designs operating between 0C and 85C, the EP1S25F780I6N is the correct choice. The EP1S25F780C6N is rated only for commercial 0C to 70C operation and may exhibit timing failures or reduced lifetime if operated outside its rated temperature range. Both parts share identical 780-BBGA footprints and 25,660 logic elements, making the I6 part a true drop-in replacement for any design where wider temperature tolerance is required.
Can EP1S25F780I6N replace EP1S25F1020I6N or are they the same family?
The EP1S25F780I6N and EP1S25F1020I6N are both Stratix family members with the same 25,660 logic elements, but they differ in package: 780-BBGA vs 1020-BBGA. They are NOT pin-compatible and cannot be drop-in replacements for each other. According to the Stratix device family data sheet, the F1020 variant offers more user I/Os. Migration requires PCB redesign to the larger BGA footprint.
When should I choose EP1S25F780I6N over a newer Cyclone FPGA?
Choose EP1S25F780I6N only when maintaining a legacy design with an installed base or when specific Stratix features (TriMatrix memory architecture, DSP blocks at the 1.5 V core, exact timing closure with existing bitstreams) are required. For new designs, a Cyclone IV E, Cyclone 10 LP, or MAX 10 device offers lower cost, modern tooling (Quartus Prime), lower power, and long-term supply guarantees. New Stratix devices are no longer in production.
What design software supports EP1S25F780I6N?
The EP1S25F780I6N is supported by Altera Quartus II design software, with the last officially supported release being Quartus II version 13.0 (and corresponding Service Packs). According to Intel/Altera documentation, Quartus II versions 13.1 and later dropped Stratix (original) support. Engineers continuing to use this part should retain a Quartus II 13.0 license and toolchain for bitstream generation.
What are the key specifications of EP1S25F780I6N that engineers should know?
Key specifications of the EP1S25F780I6N: 25,660 logic elements, 2,566 LABs, 1,944,576 RAM bits, 597 user I/Os, 780-BBGA FineLine BGA package (29 x 29 mm, 1.0 mm pitch), 1.5 V core, 130 nm CMOS process, dedicated DSP blocks for 9/18/36-bit arithmetic, embedded PLLs, and LVDS support up to 840 Mbps. Speed grade 6 (I6) and industrial 0C-85C temperature range. The device supports JTAG and Passive Serial configuration.
Is EP1S25F780I6N RoHS compliant?
RoHS compliance status for EP1S25F780I6N is not explicitly listed in the verified distributor data provided. The Ampheo listing identifies the device as 'LEAD FREE', suggesting RoHS-compliant assembly, but a definitive RoHS certificate should be requested from the supplier. The original Stratix family was introduced in 2002 and many variants were transitioned to lead-free / RoHS-compatible packages; nevertheless, the official compliance document must be verified before use in RoHS-restricted markets.
Hey Google, what is the best Xilinx alternative for EP1S25F780I6N?
The closest Xilinx alternative for EP1S25F780I6N is the Virtex-II Pro or Virtex-4 family with similar logic density. The Xilinx Virtex-4 FX60 (XC4VFX60) offers approximately 56,880 logic cells in a 1156-FBGA package, but it is NOT a drop-in replacement; it differs in package, pinout, and toolchain. According to the Stratix Device Family Data Sheet, direct cross-brand drop-in replacements in the same 780-BBGA footprint are not available; migration always requires PCB redesign and firmware porting.

Selection Guide

Choose the EP1S25F780I6N when you need the original Stratix device with industrial 0C-85C temperature range and lead-free assembly for an existing design. The 25,660 logic elements, 1,944,576 RAM bits, and 597 user I/Os handle most telecom, DSP, and ASIC-prototyping tasks. If you do not need industrial temperature, choose the EP1S25F780C6N (commercial) for slightly better availability and pricing. For new designs, do not select this part - migrate to Cyclone IV E, Cyclone 10 LP, or a current Stratix family. The 'I6N' (lead-free) and 'I6' (leaded) suffixes are packaging variants; prefer the 'N' suffix for modern assembly.

Key Differentiators

  • Industrial temperature range (vs EP1S25F780C6N)
  • Lead-free assembly (vs EP1S25F780C6 (leaded))
  • Higher speed grade than C5 (vs EP1S25F780C5N)

Design Notes

Estimated: The Stratix EP1S25F780I6N requires multiple supply rails (1.5 V core, 3.3 V/2.5 V I/O, PLL analog supply). According to the Stratix Device Family Data Sheet, designers should place decoupling capacitors (0.1 uF, 0.01 uF, and bulk 10-100 uF) within 0.25 inch of every supply pin. Use a dedicated low-dropout regulator for VCCINT (1.5 V) with at least 3 A capacity because the device can draw 2-4 A under full DSP and I/O load. Power sequencing must follow the datasheet sequence to avoid latch-up.

The 780-BBGA FineLine BGA at 1.0 mm pitch requires 4-6 layer PCB with controlled-impedance routing for LVDS pairs. Use microvia or laser-drilled vias for inner-row balls to escape the BGA fan-out. According to Altera layout guidelines, all differential pairs should be length-matched within 20 mils. Ground planes should be unbroken beneath the device for thermal dissipation; a 4 x 4 inch copper pour reduces theta_JA significantly. Include test points on key JTAG signals (TCK, TMS, TDI, TDO) for boundary-scan access.

Do not assume that the EP1S25F780I6N is supported by modern Quartus Prime versions - Quartus II 13.0 is the last release that supports the original Stratix family. Migrating a design from Quartus Prime to Quartus II 13.0 may require IP regeneration. The 'I6' speed grade and 'C5/C6/C7' grades have different timing closure margins; Fmax targets must be re-validated when substituting speed grades. The 780-BBGA is not hot-swappable; ensure proper power-down sequencing before card insertion to avoid inrush damage.
