EP3SE80F780I4LN - 80K LE Stratix III E FPGA, 780-FCBGA | Intel
MPN: EP3SE80F780I4LN ⚠ Lần mua cuốiEP3SE80F780I4LN Tóm tắt
A Field Programmable Gate Array (FPGA) is a reconfigurable integrated circuit whose logic fabric, interconnect, and I/O behavior are defined by a user-supplied configuration bitstream. Stratix III E sits within Altera's hierarchy as: FPGA -> programmable logic device (PLD) -> logic IC -> digital semiconductor. Compared with fixed-function ASICs, FPGAs accelerate time-to-market and enable in-system design changes, while compared with earlier FPGA generations Stratix III E achieves higher logic density per Watt thanks to its 65 nm low-power process and adaptive logic modules (ALMs).
Key differentiating features of the EP3SE80F780I4LN include: 80,000 logic elements (LEs) for high-density datapath and control-plane designs; 3,200 LABs/CLBs for parallel architectural flexibility; 488 maximum user I/Os (in this F780 package variant) for wide memory and high-speed transceiver interfaces; and embedded memory of 6,843,392 bits distributed in M9K/M144K blocks. The 'I4' speed grade corresponds to an industrial temperature range, and the 'N' suffix indicates lead-free / Pb-free terminations compliant with current RoHS directives.
Architecturally, the Stratix III E family uses Altera's adaptive logic module (ALM) building block, an 8-input fracturable LUT that can be reconfigured to implement any 7-input LUT or two independent 4-input LUTs. Combined with dedicated 18x18 multipliers, MLAB memory, and high-speed serial transceivers, the EP3SE80 enables DSP-intensive designs, memory-rich packet processing, and protocol bridging without external logic. The 780-FCBGA package provides ample signal integrity for high-speed DDR/DDR2/QDR II memory interfaces and LVDS-based chip-to-chip links.
Typical applications for the EP3SE80F780I4LN include wireline telecommunications line cards, military and aerospace signal processing, high-performance DSP prototyping, broadcast video processing, and ASIC prototyping for system architects who need >70 KLE in a single device. The industrial temperature range also suits ruggedized computing and test-and-measurement platforms.
When designing with this part, pay careful attention to power-rail sequencing for the 0.9 V core, 1.1 V PLL, and 1.8/2.5/3.3 V I/O banks, and follow Altera's Stratix III PowerPlay guidelines to estimate junction temperature with the device's thermal model. Designers new to Stratix III should use the Quartus II design software for synthesis, place-and-route, and timing closure.

Ghi chú thiết kế
The EP3SE80F780I4LN requires multiple power rails: 0.9 V for the core, 1.1 V for PLLs, and 1.8/2.5/3.3 V for I/O banks depending on bank configuration. Power sequencing must follow Altera's Stratix III PowerPlay guidelines to prevent latch-up. Use a dedicated POR (power-on-reset) supervisor for each rail and observe the tRAMP specification; failure to sequence properly can cause long-term reliability issues or configuration failures. Decoupling should include 0.1 µF X7R capacitors at each power pin plus bulk tantalum or ceramic on each rail.
Estimated: with all 80 KLE active at 375 MHz and 0.9 V core, dynamic power can reach 5–8 W depending on toggle rate. The 780-FCBGA package requires adequate PCB thermal management via thermal vias under the exposed die pad and inner copper planes. Without thermal vias, junction temperature can exceed the 100 °C industrial limit in still-air environments; a heatsink or forced-air cooling is recommended for high-activity designs.
The 780-FCBGA package has a 1.0 mm ball pitch and requires microvia or via-in-pad PCB technology for reliable breakout. Use a 12-layer or higher stack-up with dedicated ground and power planes. Matched-length routing is mandatory for LVDS, DDR2, and QDR II memory interfaces; follow Altera's Stratix III board design guidelines for skew budgets. Decoupling capacitors must be placed within 100 mils of their respective power pins to minimize parasitic inductance.
Common pitfalls: (1) leaving configuration mode pins (MSEL) floating; (2) using unsupported JTAG IDCODE values; (3) violating the absolute maximum 1.0 V on the 0.9 V core rail; (4) exceeding the 488 user I/O count in pin assignments; (5) ignoring Quartus II fitter warnings about I/O bank VCCIO constraints. Always run the Quartus II design assistant and TimeQuest timing analyzer before tape-out to catch these issues.
