EP3SE50F780C3 Descripción general
An FPGA (Field Programmable Gate Array) is a type of integrated circuit containing an array of configurable logic blocks (CLBs), programmable interconnects, and dedicated hard IP blocks such as DSP slices, block RAM (BRAM), PLLs, and high-speed transceivers. FPGAs belong to the broader category of programmable logic devices (PLDs) within digital semiconductors, sitting alongside CPLDs and structured ASICs. The Stratix III E variant emphasizes high logic density and DSP throughput for compute-bound applications where microcontrollers or DSP processors cannot keep pace.
Key features include up to 47,500 logic elements, 5,760 Kbits of embedded memory (BRAM), dedicated 18x18 multipliers and DSP blocks for fixed/floating-point acceleration, integrated PLLs for clock management, and 488 general-purpose user I/Os supporting LVDS, LVTTL, LVCMOS, and other single-ended and differential I/O standards. The Stratix III E architecture introduces adaptive logic modules (ALMs) for finer-grained packing efficiency compared to the previous Stratix II generation.
The EP3SE50F780C3 also integrates transceiver capabilities and partial reconfiguration support, allowing portions of the fabric to be reprogrammed while the remainder of the device continues operation. This is particularly useful for systems requiring firmware updates, A/B redundancy, or runtime algorithm switching. The 65 nm process node balances performance and leakage, though later Intel FPGA families (Stratix IV, V, 10) have since migrated to finer nodes.
Typical applications include high-speed digital signal processing for communications infrastructure, military radar and electronic warfare, medical imaging accelerators (CT, MRI, ultrasound), ASIC prototyping, and high-throughput video broadcast equipment. The combination of logic density and DSP blocks makes the device suitable for parallel filter banks, FFT pipelines, and forward-error-correction engines.
When designing with this part, verify that the Quartus II design software version (typically Quartus II 9.1 to 13.1 depending on Service Pack) supports the specific device and is licensed for SignalTap or Logic Analyzer features if needed. The 780-ball FC-FBGA package requires a multi-layer PCB with controlled-impedance routing and matched-length traces for high-speed I/O.

Aplicaciones típicas
EP3SE50F780C3 es adecuado para 6 aplicacións: High-Speed Digital Signal Processing, Telecommunications Infrastructure, Military Radar and Electronic Warfare, Medical Imaging Acceleration, ASIC Prototyping, Video Broadcast and Image Processing.
High-Speed Digital Signal Processing
The EP3SE50F780C3 is well-suited for high-throughput DSP pipelines such as FFT engines, channelizers, and digital up/down converters. Its 47,500 logic elements combined with dedicated Stratix III DSP blocks (18x18 multipliers with accumulate) deliver hundreds of GMACs of compute density, while 5,760 Kbits of embedded BRAM supports large coefficient tables and sample buffering. The 780-ball FC-FBGA package exposes 488 user I/Os for parallel data paths. Placed on the signal-processing daughter card, it typically runs alongside external DDR2/QDR memory controllers instantiated in HDL for streaming data ingest. The 500 MHz transceiver capability also enables direct interfacing to high-speed serial ADCs/DACs.
Recomendado
Telecommunications Infrastructure
The EP3SE50F780C3 serves as a fabric engine for baseband processing, forward-error-correction (Turbo, LDPC), and framer/mapper functions in wireless base stations and optical transport platforms. The 488 user I/Os handle CPRI/OBSAI backhaul interfaces and multiple SFP+/XFP transceiver channels, while the built-in PLLs generate jitter-compliant clocks. The 65 nm process node provides deterministic timing closure required for carrier-grade telecom equipment. In typical designs, the FPGA is paired with a host processor running control-plane software and external PHY chips. Power consumption and thermal design should be validated against the Stratix III power calculator early in the design flow.
Recomendado
Military Radar and Electronic Warfare
The EP3SE50F780C3 is widely deployed in radar signal-processing subsystems (pulse compression, MTI filtering, beamforming) and electronic-warfare receiver chains (DF, deinterleaving). Its DSP and BRAM density enable real-time processing of wideband IF samples, while 488 user I/Os handle ADC/DAC data and synchronization with RF front ends. The 780-ball FC-FBGA package supports ruggedized board assemblies. For harsh environments, the industrial-grade EP3SE50F780I3 variant extends the temperature range to -40C to +100C. Designers typically use Quartus II with SignalTap II logic analyzer for in-system debug, paired with VITA-49 or proprietary sample-stream protocols.
Recomendado
Medical Imaging Acceleration
In CT, MRI, and ultrasound imaging systems, the EP3SE50F780C3 accelerates back-projection, image reconstruction, and beamforming algorithms. Its parallel logic and DSP slices dramatically reduce reconstruction latency versus CPU-only pipelines, while 5,760 Kbits of BRAM holds intermediate image data and lookup tables. The device's reliability and medical-grade life-cycle support make it appropriate for long-lived diagnostic equipment. Designers typically implement custom filter back-projection or iterative reconstruction in HDL, with external DDR2/QDR memory buffers. PCBs often pair the FPGA with high-speed ADCs and high-bandwidth PCIe links to the host CPU.
Recomendado
ASIC Prototyping
The EP3SE50F780C3 serves as a hardware vehicle for verifying ASIC/SoC designs before tape-out. Its 47,500 logic elements, generous BRAM, and 488 I/Os provide a realistic run-time environment for testing register-transfer-level (RTL) code with real-world I/O stress. Multi-FPGA partitioning tools (Synopsys Certify, Mentor Graphics Precision) map large ASIC designs across multiple Stratix III E devices. Designers typically use the 780-ball FC-FBGA for high-pin-count ASIC prototypes and pair the FPGA with high-speed memory and protocol bridges. Comprehensive in-system debug is supported via SignalTap II and external logic analyzers attached to the prototype board.
Recomendado
Video Broadcast and Image Processing
The EP3SE50F780C3 drives high-resolution video processing for broadcast routers, video-wall controllers, and professional AV equipment. Its 488 user I/Os accommodate multiple SDI/HDMI/DVI input-output streams, while DSP blocks accelerate color-space conversion, scaling, and overlay blending. The 5,760 Kbits of embedded BRAM line-buffers full-HD frames in real time. Broadcast-grade designs often implement genlocking, frame synchronization, and ancillary-data processing in HDL. Designers typically pair the FPGA with external video PHYs and frame buffers (DDR2 SDRAM). The 780-ball FC-FBGA supports the high pin count needed for multi-channel I/O fanout.

Notas de diseño
Estimated: The 780-ball FC-FBGA package of EP3SE50F780C3 has a typical ball pitch of 1.0 mm. PCB design requires a high-layer-count stack-up (10+ layers) with microvia or via-in-pad technology, plus matched-length impedance-controlled routing for high-speed I/O banks. Use the Altera/Altera pinout file in Quartus II 13.1 or earlier to generate the land pattern and verify against the manufacturer's package specification before committing to PCB fabrication.
Estimated: At full fabric utilization with sustained DSP activity, the EP3SE50F780C3 can dissipate 5-8 W. Designers should attach a heatsink or thermal interface material (TIM) and provide at least 4 oz copper pours beneath the package's exposed thermal regions to keep junction temperature within the 0C to +85C commercial range. Use the Stratix III PowerPlay Early Power Estimator to model worst-case power before PCB layout.
Do not assume Quartus Prime supports Stratix III E - the final Quartus II release that supports Stratix III is version 13.1 (and earlier with service packs). Newer Quartus versions dropped support. Also verify MSEL[3:0] configuration mode strap pins (AS, PS, JTAG, FPP) match your configuration EPCS/EPCQ flash and JTAG chain. Misconfigured MSEL can cause silent configuration failures that look like dead boards.
Estimated: For DDR2/QDR II memory interfaces in EP3SE50F780C3 designs, use the Altera External Memory Interface Toolkit to validate read/write margins. Match address/command and clock trace lengths within +/- 25 ps for 400 Mbps operation. Series-termination resistors may be required on high-fanout clock nets to control overshoot. Always perform post-layout simulation with IBIS models before tape-out.
