EP1S25F672I7N - 25,660 LE Stratix FPGA, 672-FBGA | Intel / Altera
MPN: EP1S25F672I7N ✗ Cuối đờiEP1S25F672I7N Tóm tắt
An FPGA (Field Programmable Gate Array) is a reconfigurable digital logic device that allows hardware designers to implement arbitrary digital functions after PCB assembly. Stratix devices occupy the high-density, feature-rich tier of the Altera/Intel programmable logic hierarchy, sitting above Cyclone (cost-optimized) and below Stratix GX (transceiver-equipped) and Stratix II/GX (next-generation). Within a power management or embedded system, FPGAs serve as hardware accelerators, protocol bridges, glue logic, and signal-processing engines. FPGAs differ from MCUs in that logic and interconnect are user-defined rather than fetched from firmware, enabling deterministic parallel throughput.
Key features of the EP1S25F672I7N include up to 25,660 logic elements, 1.9 Mbit embedded TriMatrix memory, dedicated 18×18 multipliers for DSP, support for high-speed external memory interfaces such as DDR SDRAM, QDR SRAM, and ZBT SRAM, and dedicated serial configuration support via passive serial, fast passive parallel, and JTAG. The 672-pin FineLine BGA package measures 35 × 35 mm with 1.27 mm pitch and is optimized for high pin-count, multi-layer PCB layouts.
Architecturally, the Stratix family introduced the TriMatrix memory architecture with three block sizes (M512, M4K, M-RAM) to optimize silicon area across distributed and buffer-style memory requirements. The 1.5 V core supply is supported by on-chip voltage regulation requiring only a single external supply input, simplifying power tree design compared to earlier 2.5 V / 3.3 V core architectures.
Typical applications include telecom line-card packet processing, military/aerospace signal processing, medical imaging accelerators, industrial machine vision, and ASIC prototyping. The wide DSP block density also suits software-defined radio baseband and digital video broadcasting infrastructure.
When designing with this device, allocate 1.5 V core and dedicated PLL/IO supply rails with decoupling placed close to each BGA quadrant. Use Altera Quartus II (legacy) or Intel Quartus Prime for synthesis, place-and-route, and timing closure. Note that this part is mature legacy silicon; new designs should consider Stratix IV/V or Cyclone families for active long-term supply.

Ứng dụng tiêu biểu
EP1S25F672I7N phù hợp cho 6 Áp dụngs: Telecom Line-Card Packet Processing, ASIC Prototyping and Emulation, Industrial Machine Vision, Software-Defined Radio Baseband, Military and Aerospace Signal Processing, Medical Imaging Accelerator.
Telecom Line-Card Packet Processing
The EP1S25F672I7N's 25,660 logic elements and 1.9 Mbit TriMatrix memory suit wire-speed packet classification and queuing engines in telecom line cards. At a -7 speed grade it sustains internal clocks near 420 MHz, enabling OC-48/STM-16 (2.488 Gbps) class data plane processing without external TCAM. Place Ethernet framer and SERDES glue logic in fabric, push flow tables into M4K blocks, and use dedicated multipliers for hashing. The 473 user I/O let designers fan out to multiple SFP/uplink SERDES. Industrial temperature supports outdoor cabinet deployments.

ASIC Prototyping and Emulation
Designers targeting ASIC tape-out use the EP1S25F672I7N as an emulation vehicle for sub-million-gate RTL. Its 1.5 V Stratix architecture and Quartus II support make pre-silicon validation of ASIC RTL straightforward, with the 672-FBGA exposing enough I/O to model 473 signal pins plus JTAG and clock pins. Industrial temperature allows in-circuit emulation under stress. For multi-FPGA partitioning the larger EP1S40/EP1S60 parts extend capacity while keeping the Quartus flow identical.
Được đề xuất
Industrial Machine Vision
Camera-link and CoaXPress front-end image processing pipelines fit naturally inside the EP1S25F672I7N. Dedicated 18×18 multipliers and 1.9 Mbit TriMatrix memory handle Bayer demosaicing, color-space conversion, and edge detection at gigapixel/sec rates. Industrial temperature grade (0-85C) supports factory-floor enclosures. The 672-FBGA exposes enough user I/O to sink Camera-Link LVDS pairs directly into the FPGA without external transceivers, lowering BOM cost in vision-system designs.
Được đề xuất
Software-Defined Radio Baseband
The 1.5 V Stratix silicon in EP1S25F672I7N hosts wide-band digital down/up-converters and channelizers for software-defined radio. Embedded multipliers accelerate complex FFT/iFFT operations, while TriMatrix memory stages overlap-save buffers. Paired with external ADC/DAC, the FPGA implements full IF-to-baseband processing for narrow-band tactical radios. Industrial temperature and the mature Quartus II toolchain keep legacy SDR platforms supportable, although new designs should consider Cyclone V or Stratix V for active long-term supply.
Được đề xuất
Military and Aerospace Signal Processing
Defense-grade signal-processing subsystems benefit from the EP1S25F672I7N's industrial temperature range and mature Altera silicon, though true MIL-spec flow requires separate screening. Radar pre-processing, electronic-warfare channelizers, and secure-comm DSP fit inside 25,660 LEs and 1.9 Mbit memory. The 672-FBGA's 1.27 mm pitch balances I/O count with PCB manufacturability. Programs already fielded with original Stratix can sustain production through obsolescence-mitigation brokers sourcing this exact MPN.
Được đề xuất
Medical Imaging Accelerator
Ultrasound beamforming and MRI reconstruction engines map cleanly onto the EP1S25F672I7N's parallel fabric. The 1.9 Mbit TriMatrix memory holds beamformed line buffers; 18×18 multipliers implement FIR/IIR filters and complex mixers for quadrature demodulation. The 672-FBGA exposes enough LVDS pairs to receive raw transducer data directly, while the industrial temperature range supports imaging-cart environments. Mature Quartus II IP libraries (FFT, FIR, NCO) shorten development cycles for FDA-cleared medical platforms.

Ghi chú thiết kế
Estimated: at full logic utilization and 420 MHz internal clocks, the EP1S25F672I7N can draw 1.5–2.0 A from the 1.5 V core rail plus per-bank VCCIO. Use a low-impedance power plane with bulk and high-frequency decoupling (220 µF bulk + 10 µF + 0.1 µF + 1 nF) within 5 mm of each BGA quadrant. Sequence VCCINT before VCCIO if your downstream devices require it; Stratix allows simultaneous ramp but a slight delay improves inrush behavior.
Estimated: at 1.5 V × 2 A core plus typical I/O switching, total dissipation is roughly 4 W. The 672-FBGA has no exposed top-side heatsink path, so cooling relies on copper pour under the package plus package-top airflow. Keep junction-to-ambient below 35 °C/W for industrial operation. For sealed enclosures, add a 10 × 10 mm copper slug directly under the BGA footprint to spread heat into inner PCB layers.
The 672-ball FineLine BGA uses 1.27 mm pitch and 35 × 35 mm body, requiring microvia or laser-drilled via technology for inner escape. Stack the PCB at minimum 6 layers with two dedicated GND planes adjacent to the BGA. Per JEDEC J-STD-020, the package supports reflow profiles up to 260 °C peak. Use ENIG or OSP surface finish for fine-pitch BGA reliability.
Do not confuse the EP1S25F672I7N with the EP1S25F1020 variants — the 1020-ball package exposes more I/O but is pin-incompatible with 672-ball designs. Use Altera Quartus II 13.0sp1 (final version with original Stratix support) — newer Quartus Prime releases dropped original Stratix synthesis. Confirm date code and country of origin when sourcing from broker channels to avoid counterfeit risk on legacy FPGAs.
