MPN: EP3SE50F780I3N ⚠ Lần mua cuốiEP3SE50F780I3N Tóm tắt
A Field-Programmable Gate Array (FPGA) is a type of programmable logic device that allows engineers to implement custom digital circuits by configuring an array of configurable logic blocks (CLBs), programmable interconnects, and dedicated hard IP blocks such as DSP slices, M20K memory blocks, transceivers, and PLLs. FPGAs sit within the semiconductor hierarchy: programmable logic -> logic IC -> integrated circuit, and serve as the highest-density reconfigurable digital fabric between microcontrollers and custom ASICs. Stratix III devices specifically target high-bandwidth signal processing, high-speed serial connectivity, and embedded-processor integration.
Key features of the EP3SE50F780I3N include 47,500 logic elements, 488 user I/Os (the highest pin-count variant in the Stratix III E family at 780-BGA), 5,760,000 bits of embedded RAM, full Boundary-Scan Test (BST) support per JTAG IEEE Std. 1149.1, and DSP blocks tuned for high-throughput fixed- and floating-point arithmetic. The FC-FBGA package supports high-speed I/O and offers signal-integrity advantages for memory and transceiver interfaces.
Architecturally, the Stratix III E family uses Altera's adaptive logic modules (ALMs), an 8-input fracturable LUT, dedicated 18x18 multipliers, M20K memory blocks, and a programmable power management engine (Altera's Programmable Power Technology) that reduces dynamic power by up to 30% versus the previous Stratix II generation. Device configuration is supported through JTAG IEEE 1149.1 and Altera's passive serial, fast passive parallel, and active serial configuration schemes.
Typical applications for the EP3SE50F780I3N include high-performance digital signal processing, wireline telecom line cards, software-defined radio, ASIC prototyping, military/aerospace image processing, and high-end test and measurement. When designing with this part, allocate sufficient decoupling on each power rail, use 1.0 V core and 0.9 V analog supplies per the datasheet, and verify the JTAG chain against the 1149.1 boundary-scan architecture before board bring-up.

Ứng dụng tiêu biểu
EP3SE50F780I3N phù hợp cho 6 Áp dụngs: High-Performance Digital Signal Processing, ASIC Prototyping and Emulation, Wireline Telecom Line Cards, Military and Aerospace Signal Processing, Software-Defined Radio Baseband, Test and Measurement Instrumentation.
High-Performance Digital Signal Processing
The EP3SE50F780I3N's 47,500 logic elements and Stratix III E family's enhanced DSP blocks make it well-suited for high-throughput DSP workloads. The E variant packs more 18x18 multipliers and M20K memory blocks than the L variant, delivering higher DSP bandwidth for FFTs, FIR filters, and forward-error-correction pipelines. With 0.9 V core operation and industrial temperature grade, the part handles signal-processing cards in outdoor or ruggedized telecom platforms.

Ghi chú thiết kế
Decouple each Stratix III power rail (VCCINT 0.9 V, VCCIO 1.2-3.0 V per bank, VCCPD, VCCAUX, VCCBAT) with the capacitor network recommended in the Stratix III Power Management chapter. Place 0.1 uF and 10 uF ceramics within 100 mils of each pin pair. Use PowerPlay Early Power Estimator before layout to size the regulator; at maximum DSP throughput the EP3SE50F780I3N can draw 5-10 W from VCCINT alone. Sequence rails as documented in the datasheet to avoid latch-up.
The 780-ball FC-FBGA package requires a multilayer PCB with microvia stack-ups. Per JEDEC/IPC-9701, design 1-2-1 or 1-2-1-2-1 stack-ups with laser-drilled microvias on the top/bottom and filled/via-in-pad for the BGA pads. Match trace impedance to 50 ohm single-ended / 100 ohm differential for high-speed transceiver and LVDS pairs. Keep at least 4-6 ground return vias stitched around the BGA perimeter to provide a low-impedance return path.
Do not apply power before the configuration is complete and the CONF_DONE pin goes high - earlier transitions can corrupt the FPGA state. Wire the JTAG chain with TRST properly tied through the recommended resistor network; floating TRST can randomly put the device in test mode. When migrating from EP3SE50F780I3N to the EP3SE50F484I3N or another footprint, verify the Quartus II pin-out file (.pin) for every pin - same silicon, different package, different ball-to-pin mapping.
