Typical Applications
EP1S25B672C6 is suitable for 6 applications: Telecommunications Line Card Processing, High-Speed DSP Pipeline (Radar/Sonar/Image Processing), ASIC Prototyping and Emulation, Industrial Motion Control and Motor Drives, High-Performance Data Acquisition Systems, Legacy Medical Imaging Equipment.
Telecommunications Line Card Processing
The EP1S25B672C6's 25,660 logic elements, 1,944,576 bits of TriMatrix RAM, and 473 user I/Os make it a strong fit for telecom line cards requiring parallel protocol processing, packet inspection, and backplane bridging. Its six dedicated DSP blocks deliver hardware-accelerated filtering for voice and baseband codecs, while the 12 PLLs provide multiple clock domains for interfacing to TDM buses, SERDES framer ICs, and Ethernet MACs. At 1.5V core supply and 130nm process, the EP1S25 is well-suited to legacy SONET/SDH and ATM designs still in service.
Recommended
High-Speed DSP Pipeline (Radar/Sonar/Image Processing)
The EP1S25B672C6 integrates six dedicated DSP blocks each containing hardware multipliers and adder trees, ideal for FIR filters, FFT butterflies, and matrix multiply operations in radar, sonar, and machine-vision pipelines. Its 450 MHz internal clock headroom enables real-time baseband processing at sample rates above 100 MSPS, while 1,944,576 bits of TriMatrix memory buffer data between ADC front-ends and downstream processing. The 672-BGA package supports thermal dissipation up to roughly 8W with appropriate PCB copper area.
Recommended
ASIC Prototyping and Emulation
The EP1S25B672C6 was widely used in the mid-2000s as an ASIC prototyping vehicle, where its 25,660 LEs could be partitioned across multiple FPGAs to emulate a million-gate ASIC. The 473 user I/Os provide ample connectivity for multi-FPGA prototyping boards and logic analyzer-style probing. TriMatrix memory in dual-port and FIFO modes simplifies emulation of on-chip RAMs, while the 12 PLLs generate clocks matching the target ASIC's clock tree. Engineers maintaining legacy emulation platforms continue to specify the EP1S25 for board-level compatibility.
Recommended
Industrial Motion Control and Motor Drives
The EP1S25B672C6 fits industrial motion control applications needing deterministic parallel servo loop execution, encoder feedback processing, and high-speed PWM generation. Its 12 PLLs allow precise synchronization to resolver/excitation frequencies and fieldbus clocks (PROFIBUS, CANopen), while 473 I/Os support multiple axis drives in a single FPGA. The 1.5V core and 130nm process deliver robust noise immunity in motor-drive EMI environments, though the commercial 0-85C temperature range limits deployment; the EP1S25B672I6 industrial variant extends to -40C to +100C.
Recommended
High-Performance Data Acquisition Systems
With 473 user I/Os and 1.9 Mbits of dual-port embedded RAM, the EP1S25B672C6 serves as the central FPGA in multi-channel data acquisition systems digitizing analog signals from ADCs running at 100+ MSPS. TriMatrix memory configured as true dual-port blocks enables simultaneous ADC write and DSP read, eliminating external FIFOs. The 12 PLLs derive multiple synchronized clocks for ADC sampling, DAC reconstruction, and downstream DSP processing, while LVDS support on select I/O banks enables direct connection to LVDS-serial ADC outputs.
Recommended
Legacy Medical Imaging Equipment
The EP1S25B672C6 continues to serve in installed-base medical imaging equipment such as ultrasound beamformers, MRI gradient controllers, and X-ray detector readout boards where design re-validation costs far exceed component savings. Its 25,660 LEs and DSP blocks handle real-time beamforming computations, while 1,944,576 RAM bits buffer raw RF and image data. With the EP1S25 now in Obsolete lifecycle status as of 2026-09-07, medical OEMs are advised to qualify the EP1S25B672C7N or the EP1S25B672C6N lead-free variant for new production runs to extend equipment service life.

Design Notes
Estimated: The EP1S25B672C6 in a 672-BGA package dissipates up to approximately 8W at full utilization (all 25,660 LEs switching at 450 MHz with all six DSP blocks active). Theta_JA for the 672-BGA is approximately 8 C/W with a JEDEC JESD51 4-layer test board. Junction temperature rise at 8W is therefore roughly 64C above ambient - confirm adequate PCB copper area (at least 25 cm^2 of unbroken ground plane under the BGA) and forced-air cooling for sustained operation in industrial environments.
The 672-BGA requires a multi-layer PCB with microvia or via-in-pad construction to fan out the 1.0 mm pitch BGA balls. Per Altera layout guidelines, use 4-6 PCB layers with dedicated ground and power planes; place 0.1 uF decoupling capacitors on every VCCIO/VCCINT pin within 100 mils of the pad. For JTAG and configuration signals (TCK, TMS, TDI, TDO, nCONFIG, nSTATUS, CONF_DONE), use 4.7k-ohm pull-ups to VCCIO as specified in the Stratix handbook configuration chapter.
The EP1S25B672C6 is Obsolete as of 2026-09-07 per Octopart; verify last-time-buy availability from authorized distributors and stockpile for production lifetime needs. Do NOT substitute a Stratix II EP2S25 without board respin - Stratix II moves from 1.5V to 1.2V core, adds new I/O features, and changes pin functions. For new designs, consider Cyclone IV/Arria II as low-cost/low-power successors with the same Quartus II toolchain. Verify configuration device selection (EPCS1/EPCS4 for serial, EPC16 for parallel).
The EP1S25B672C6 supports LVDS on specific I/O banks (typically banks 3, 4, 7, 8 - refer to device handbook pin tables). When routing LVDS pairs, maintain 100 ohm differential impedance and match trace lengths to within 20 mils to avoid skew-induced jitter. SSTL/HSTL interfaces to external DDR SDRAM require VREF reference voltage planes; place VREF decoupling capacitors (0.1 uF + 10 uF) near each VREF pin. For clock inputs to global clock buffers, use the dedicated CLK pins (e.g., CLK0-CLK15) for best skew performance.
Compliance Information
Specific RoHS/REACH compliance data for the EP1S25B672C6 was not present in the verified web data as of 2026-09-07; consult the manufacturer product declaration or Intel PCN archive for definitive status. The Pb-free N-suffix variants (e.g., EP1S25B672C6N, EP1S25B672C7N) are confirmed Pb-free per Stratix family nomenclature.
