EP1S25F780C5N - 25K LE Stratix FPGA 780-FBGA | Intel
MPN: EP1S25F780C5N ✗ Cuối đờiEP1S25F780C5N Tóm tắt
An FPGA is a semiconductor device built around an array of configurable logic blocks (CLBs/LABs) connected by programmable interconnect. The bitstream stored in on-chip SRAM configures both the logic function of each block and the routing between them. FPGAs are widely used for high-performance parallel processing, glue logic, prototyping, and ASIC replacement where time-to-market matters more than per-unit cost. The Stratix family in particular was the first Intel/Altera platform to embed dedicated DSP blocks, TriMatrix memory, and high-speed transceivers on-chip.
Key features of the EP1S25F780C5N include up to 1.92 Mbits of embedded TriMatrix memory, dedicated DSP blocks for fixed- and floating-point arithmetic, support for multiple I/O standards (LVTTL, LVCMOS, SSTL, HSTL, LVDS, LVPECL), and 4 phase-locked loops (PLLs) for clock management. The 597 user I/O pins are organized into 12 I/O banks, supporting a wide range of single-ended and differential interfaces including PCI, PCI-X, DDR, and RapidIO. The 780-pin FBGA package enables high signal density for complex board designs.
The device supports configuration via passive serial, passive parallel synchronous, passive parallel asynchronous, and JTAG modes. Configuration bitstreams are stored in external EEPROM or flash and loaded into on-chip SRAM at power-up. The 130 nm process provides a mature, well-characterized fabric with proven reliability for telecom, industrial, and military applications.
Typical applications include high-throughput digital signal processing (radar, software-defined radio, video processing), telecom line cards, ASIC prototyping, industrial control systems, and high-speed serial interface bridging. The combination of large logic capacity and dedicated DSP blocks makes the EP1S25 well suited for data-path intensive designs where parallel arithmetic performance is critical.
When designing with this device, pay close attention to power sequencing and decoupling. The 780-FBGA package requires a multi-layer PCB with continuous power and ground planes. Use the Quartus II design software (version 5.x or later, as required for the Stratix family) for synthesis, place-and-route, and timing closure. Note that the EP1S25 series is end-of-life as newer Stratix/Cyclone generations have superseded it; consult the Intel/Altera Product Discontinuance notices before committing to long-lifecycle designs.
This page synthesizes current distributor pricing, lifecycle status, drop-in same-package alternatives, and Quartus II design considerations not found in the original manufacturer datasheet alone.

Ứng dụng tiêu biểu
EP1S25F780C5N phù hợp cho 6 Áp dụngs: Telecom Line Card Processing, Software Defined Radio (SDR), Digital Signal Processing (DSP) Farm, ASIC Prototyping, Industrial Motion Control, High-Speed Image Processing.
Telecom Line Card Processing
The EP1S25F780C5N's 25,660 logic elements and dedicated DSP blocks make it well suited for high-throughput telecom line card processing where packet inspection, framing, and forward error correction must run at wire speed. Its 597 user I/Os support multiple SFI-4.2 / SPI-4.2 interfaces to network processors, while the four PLLs provide the multiple clock domains required for ingress and egress paths. Placed between a framer and a network processor, the device can absorb protocol conversion overhead without burdening the host CPU. Trade-off: at 130 nm process and 1.5 V core, power dissipation per LE is higher than modern Stratix V/10 parts, so thermal design must account for 5 to 10 W typical board-level dissipation.
Được đề xuất
Software Defined Radio (SDR)
The EP1S25F780C5N is widely used in software-defined radio platforms where its 25,660 logic elements plus dedicated DSP blocks deliver the FIR filter, FFT, and modulation/demodulation throughput required for multi-channel baseband processing. The TriMatrix memory provides on-chip buffering that lets designers minimise external SDRAM accesses, raising effective throughput by 2x to 4x versus discrete DSP implementations. Up to 500 MHz internal logic rates support real-time OFDM and WCDMA signal chains. Trade-off: the part lacks hard multi-Gigabit transceivers, so high-speed ADC/DAC interfaces must be implemented through general-purpose I/O, limiting the part to sub-1 Gsps converter rates.
Được đề xuất
Digital Signal Processing (DSP) Farm
The EP1S25F780C5N's dedicated DSP blocks deliver up to 420 MHz multiply-accumulate performance, making the device a strong choice for DSP farms that implement FIR filters, FFT cores, and adaptive equalisers in parallel. The 597 user I/Os expose multiple high-speed LVDS pairs for connecting to analog front-end ADCs and DACs in radar, sonar, and instrumentation systems. With 12 I/O banks the device can simultaneously interface with DDR memory, LVDS data converters, and legacy parallel buses. Trade-off: the 130 nm process limits the achievable DSP block count per watt; designers should benchmark against Stratix III/IV for new deployments where power budget is tight.
Được đề xuất
ASIC Prototyping
The EP1S25F780C5N's 25,660 logic elements and 597 user I/Os make it a common platform for ASIC prototyping where designers map a multi-million-gate ASIC into one or more Stratix FPGAs for pre-silicon validation. The TriMatrix memory blocks can be reconfigured as RAM, ROM, or FIFO, allowing precise modelling of the target ASIC's memory subsystem. Up to 500 MHz internal operation supports system-speed bring-up of complex SoCs. Trade-off: ASIC prototypes must account for the Stratix routing delay penalty, which typically means the FPGA prototype runs 3x to 5x slower than the final silicon; plan verification cycles accordingly.
Được đề xuất
Industrial Motion Control
The EP1S25F780C5N's large logic capacity and DSP blocks are well suited for multi-axis industrial motion controllers, where each axis requires PID loops, trajectory planning, and encoder interface logic. The 597 I/Os can simultaneously drive stepper/digital servo amplifiers, quadrature encoders, and safety-rated emergency-stop chains across multiple axes. Industrial temperature grade variants (the EP1S25F780I5N drop-in) extend operation from -40 C to 100 C for factory-floor environments. Trade-off: industrial customers increasingly prefer Cyclone IV/V or newer families for long lifecycle support, so treat the EP1S25 as a maintenance component for legacy controllers.
Được đề xuất
High-Speed Image Processing
The EP1S25F780C5N delivers the throughput required for real-time video pipelines such as HD-SDI capture, image scaling, and edge detection in surveillance and broadcast equipment. The device's LVDS-capable I/Os at up to 840 Mbps can ingest CameraLink or HD-SDI streams directly, while the embedded TriMatrix memory buffers several frames of video data without external SRAM. Designers can implement full H.264 motion estimation, scaling, and overlay logic on a single chip. Trade-off: the part lacks dedicated video processing IPs in the silicon; most video functions must be implemented in fabric, consuming 60 to 80 percent of available logic for 1080p60 pipelines.

Ghi chú thiết kế
The 780-ball FBGA package requires a minimum 6-layer PCB stack-up with continuous VCCINT and GND planes to deliver the 1.5 V core supply cleanly across the array. Use 1.0 mm-pitch escape routing and pair each VCCIO ball with at least one GND ball on adjacent rows. Estimated: at 1.5 V core and typical 25 percent toggle activity, the EP1S25F780C5N dissipates 5 to 10 W; budget 25 percent extra thermal headroom above the worst-case operating profile.
Power sequencing matters because the EP1S25 family uses separate VCCINT, VCCIO, and VCCA_PLL rails. Bring up VCCINT before VCCIO and keep VCCA_PLL within 100 mV of VCCINT during ramp to avoid CMOS latch-up. Use a supervisor IC such as the TPS38600 or equivalent 4-rail sequencer. Decouple each VCCIO bank with 0.1 uF X7R ceramics placed within 5 mm of the package ball.
Do not assume modern Quartus releases support the EP1S25 family. Use Quartus II Service Pack 2 or Service Pack 3 (version 5.1 to 7.2) for synthesis, place-and-route, and timing closure. Trying to compile with Quartus Prime 18+ will fail because the legacy device database was dropped. Plan for a Quartus II legacy toolchain if you intend to maintain or rebuild existing EP1S25 bitstreams.
Estimated: at 500 MHz core logic, full 597-I/O LVDS drive, and 1.5 V supply, the EP1S25F780C5N dissipates up to 12 W. With theta_JA around 15 C/W (4-layer JEDEC board), junction temperature can rise to 95 C above ambient in still air. Provide forced-air cooling of at least 200 LFM or attach a small heatsink via thermal pad to keep Tj below 100 C in commercial-grade operation.
