MPN: EP3SE50F780C4N ✗ סוף ייצורEP3SE50F780C4N סקירה
A field-programmable gate array (FPGA) is a semiconductor integrated circuit composed of configurable logic blocks (CLBs), programmable interconnect, and dedicated silicon resources such as block RAM, DSP blocks, and high-speed transceivers. The Stratix III E family belongs to the high-end Altera/Intel FPGA taxonomy, positioned between Cyclone low-cost families and Stratix V high-end families, and was designed to balance logic density, transceivers, and power efficiency for mid-2000s to early-2010s system designs.
Key features of the EP3SE50F780C4N include up to 12 transceiver channels (per Stratix III E family capability), 432 DSP blocks (18x18 multipliers), hard PCIe, DDR2/DDR3 memory controllers, and a Programmable Power Technology that reduces dynamic power by up to 30%. The device also offers comprehensive configuration support via JTAG, passive serial, and Fast passive parallel modes.
Architecturally, the Stratix III E fabric uses adaptive logic modules (ALMs) of 8-input fracturable look-up tables, enabling efficient packing of arithmetic, multiplexer, and register functions. Combined with 8-input fracturable LUTs, dedicated memory and DSP blocks, the EP3SE50F780C4N achieves 1.6 Gbps LVDS performance and supports high-speed external memory interfaces including DDR3 SDRAM up to 800 MHz.
Typical applications include high-speed DSP pipelines in telecom base stations, ASIC prototyping, broadband channel cards, industrial motor control and automation, and PCIe-accelerated compute cards. Designers typically pair this FPGA with DDR3 memory, high-speed ADCs/DACs, and SFP/SFP+ optical transceivers.
Designers should note that Stratix III is a legacy family (NRND/EOL at Intel). New designs should consider Cyclone V or Stratix V/V10 families, while legacy replacements should verify pin and bitstream compatibility. The 780-FBGA package uses 1.0 mm ball pitch and requires PCB design rules for fine-pitch BGA fanout.

יישומים טיפוסיים
EP3SE50F780C4N מתאים עבור 6 יישוםs: Telecom Base-Station DSP Pipeline, ASIC Prototyping and Emulation, Industrial Motor Control and Servo Drives, High-Speed ADC/DAC Signal Processing, PCIe-Accelerated Compute Cards, Broadband Channel Cards and Line Cards.
Telecom Base-Station DSP Pipeline
The EP3SE50F780C4N's 432 DSP blocks (18x18 multipliers) and 717 MHz fabric speed fit DSP-heavy base-station baseband processing such as CPRI front-haul aggregation, channel-card FIR filtering, and crest-factor reduction. Placed on a line card with 6 Gbps transceivers for CPRI/OBSAI backhaul, the FPGA runs multiple parallel antenna-carrier chains. With 5.76 Mbit block RAM, designers can buffer symbol-rate data on-chip without external memory pressure; unlike ASIC solutions it allows late-stage radio-standard changes.
מומלץ
ASIC Prototyping and Emulation
With 47.5K LEs, 5.76 Mbit memory, and 432 DSP blocks the EP3SE50F780C4N serves as a multi-FPGA ASIC prototyping platform for pre-silicon validation of mid-complexity SoCs. Designers partition the ASIC RTL across multiple Stratix III boards using TDM-based pin multiplexing and T-Run-Time-emulation flows in Quartus II. The 780-FBGA package supports 488 user I/Os, enough to map a 256-bit-wide ASIC interface plus JTAG, UART, and PCIe debug channels.
מומלץ
Industrial Motor Control and Servo Drives
The EP3SE50F780C4N drives multi-axis industrial servo loops with high-resolution PWM, encoder decoding, and field-oriented control (FOC) algorithms. Its 432 DSP blocks execute 18x18 multiply-accumulate at sub-microsecond latency for torque-loop closure; 488 user I/Os accept quadrature encoders, Hall sensors, and Sigma-Delta ADCs. Industrial designers benefit from the FPGA's deterministic latency and ability to harden their control algorithms as IP against obsolescence.
מומלץ
High-Speed ADC/DAC Signal Processing
Stratix III E's up-to-12 transceiver channels operating at 6.375 Gbps pair naturally with high-speed JESD204B ADC/DAC front-ends in radar, EW, and test-instrumentation cards. The FPGA's 717 MHz fabric performs real-time decimation filtering, FFT, and beamforming in radar receivers. The 5.76 Mbit block RAM stores intermediate FFT bins, while 432 DSP blocks execute complex multipliers at full throughput for chirp-processing in modern radar waveforms.
מומלץ
PCIe-Accelerated Compute Cards
Stratix III E hard PCIe IP blocks (x1/x4/x8 Gen1-2) make the EP3SE50F780C4N a strong fit for PCIe-form-factor compute accelerators in image processing, financial Monte Carlo, and database query offload. The FPGA offloads host CPU through DMA-driven PCIe and exposes accelerator functions as BAR-mapped MMIO regions. 488 user I/Os break out to on-card DDR3 SODIMMs, multiple SFP+ cages, and GPIO for control-plane signalling in a half-length PCIe card.
מומלץ
Broadband Channel Cards and Line Cards
Stratix III E cards in ATCA / AdvancedTCA and proprietary chassis aggregate 10G/40G optical links using the FPGA's high-speed transceivers. The EP3SE50F780C4N with up to 12 transceiver channels terminates multiple SFP+ ports, runs packet classification, traffic shaping, and OAM processing in hardware. 5.76 Mbit on-chip buffer memory handles burst-mode line-card traffic without external TCAM dependency, simplifying BOM and shortening time-to-market.

הערות תכנון
Estimated: At 50% utilization, 400 MHz core frequency, and full transceiver activity, the EP3SE50F780C4N dissipates approximately 6-12 W. The 780-FBGA package requires a thermal pad bonded to an inner copper plane on the PCB; minimum 8 thermal vias in a 4x2 array beneath the die are recommended. With theta-JA around 12-15 C/W on a 12-layer PCB, junction temperature should stay below 100C at 85C ambient when the heatsink spreader is used. Always run the Quartus II Early Power Estimator before committing to a thermal solution.
The 780-FBGA uses 1.0 mm ball pitch, requiring 0.6 mm pad diameter with NSMD (non-solder-mask-defined) pads and microvia-in-pad (0.1 mm/0.25 mm) escape routing. Maintain 0.5 mm trace width with 0.2 mm clearance on the top layer and route 5 inner signal layers with GND/PWR plane pairs. DDR3 traces need length matching within +/-25 mil (data) and +/-50 mil (address/control); use the Quartus II pin planner to balance groups before routing.
Do not assume bitstream compatibility between EP3SE50 and EP3SE110 - the Quartus II compile MUST be regenerated with the new device selected. Hot-swap of configuration flash between speed grades (e.g. C4 vs C5) requires only an updated .sof/.pof, but cross-die hot-swap will fail power-on. Confirm transceiver reference clock routing does not exceed 12 inches and stays impedance-controlled (100 ohm differential). Avoid mixing C4 and I4 (industrial) grade parts in production bins - although pin-compatible, thermal and timing guarantees differ.
