EP3SE50F780I3N Présentation

The Intel (formerly Altera) EP3SE50F780I3N is a high-performance Stratix III E Field-Programmable Gate Array (FPGA) IC built on a 65 nm process, integrating 47,500 logic elements, 488 user I/O pins, and 5,760,000 bits of embedded memory in a 780-ball Fine-pitch Chip-Scale BGA (FC-FBGA) package. According to the Altera/Intel datasheet, the device operates at a core voltage of 0.9 V with industrial temperature grade support and is qualified to deliver the world's highest performance and highest density 65-nm FPGA combined with the lowest possible power consumption in its generation.

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.

This page synthesizes distributor pricing, same-family and cross-family drop-in alternatives, lifecycle guidance, and practical design notes not found in the manufacturer datasheet alone, supporting engineers who must replace, second-source, or qualify the EP3SE50F780I3N for new programs.

Does EP3SE50F780I3N support JTAG boundary scan?
Yes, the EP3SE50F780I3N fully supports JTAG Boundary-Scan Test (BST) per IEEE Std. 1149.1. According to the Stratix III datasheet, BST allows testing of pin connections without physical test probes and capturing functional data while the device is operating normally. The JTAG pins are TDI, TDO, TMS, TCK, and TRST, all of which must be terminated per the datasheet guidelines for reliable configuration and test access.
What is the difference between Stratix III E and Stratix III L?
Stratix III E (Enhanced) variants like the EP3SE50F780I3N are optimized for high DSP and memory bandwidth with more DSP blocks and M20K memory blocks, while Stratix III L (Logic) variants optimize for the highest logic density and lowest static power with fewer DSP resources. For DSP-heavy DSP workloads choose the E variant; for control-plane and glue-logic choose the L variant. Both share the same 65 nm process, Quartus II tool flow, and largely compatible footprint across matched packages.
What are the key specifications of EP3SE50F780I3N that engineers should know?
Key specifications of the EP3SE50F780I3N: 47,500 logic elements, 5,760,000 bits of embedded memory, 488 user I/Os, 0.9 V core supply, 65 nm process, JTAG IEEE 1149.1 boundary-scan support, 780-ball FC-FBGA package, industrial temperature grade, and Last Time Buy lifecycle status.

Notes de conception

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.
