EP3SE260H780I3 Overview

The Intel (formerly Altera) EP3SE260H780I3 is a high-density Stratix III E FPGA built on a 65 nm process, delivering 255,000 logic elements, 16,672,768 bits of embedded memory, and 488 user I/Os in a 780-ball FineLine BGA (FC-HFBGA) package. The device integrates 10,200 LABs and 384 embedded 18x18 multipliers, providing up to 192 GMACs of DSP throughput for high-performance signal processing. An internal clock network supports operation up to 800 MHz fabric and 500 MHz logic-array frequency, with transceiver-rich variants typically reaching 717 MHz on high-speed interfaces.

An FPGA (Field Programmable Gate Array) is a reprogrammable semiconductor device containing an array of configurable logic blocks (CLBs/LABs), programmable interconnects, and dedicated hard-IP such as block RAM, DSP blocks, and high-speed transceivers. FPGAs belong to the broader category of programmable logic devices, sitting alongside CPLDs in the digital logic hierarchy and bridging the gap between fixed-function ASICs and software-driven processors. Stratix III E devices specifically target high-performance, logic-rich applications with embedded DSP and memory, paralleling Xilinx Virtex-6 in market positioning.

The EP3SE260H780I3 is part of the Stratix III E family engineered for low static and dynamic power through programmable power technology, with each LAB able to operate in high-speed or low-power mode. The 780-ball FCBGA package supports industrial temperature grades, making the part suitable for harsh-environment deployments. On-chip features include partial reconfiguration, dedicated PLL and DLL clock management, and hard memory controllers for DDR2/DDR3.

Typical applications span high-end wireline and wireless baseband processing, military radar and electronic warfare, ASIC prototyping, and high-definition video broadcast infrastructure. The device also serves medical imaging accelerator cards, high-frequency trading acceleration platforms, and test-and-measurement instrumentation where parallel DSP throughput and large on-chip memory dominate the design trade.

A key design trade-off: the 780-ball FCBGA package requires a multi-layer PCB (typically 8-12 layers) with controlled-impedance routing, microvia or via-in-pad stackups, and matched-length traces for high-speed differential pairs. Engineers should plan for thermal management (junction-to-ambient resistance typically in single-digit C/W with proper heatsinking) and consider migration paths to Stratix IV/V or Cyclone families as the Stratix III line is no longer recommended for new designs.

This page synthesizes distributor pricing, drop-in Stratix III family alternatives, and practical FPGA design notes not collected in a single place in the manufacturer datasheet.

Engineering reference data for EP3SE260H780I3 — comparison, design guidance, and compliance information.

Selection Guide

Choose the EP3SE260H780I3 when an existing Stratix III E design requires industrial-temperature qualification (-40C to +100C) and the highest I3 speed grade for timing margin. Choose EP3SE260H780I3N if you need the same industrial temp range but with explicit lead-free compliance language. Choose EP3SE260H780C3N or C2N for cost-sensitive commercial-temperature designs (0C to +85C) where the slightly slower speed grade is acceptable. Choose EP3SE260H780C4N when you need the fastest commercial speed grade for the most demanding timing closure. Choose EP3SE260H780C4LN for low-power commercial applications using Quartus II power-mode features. All five alternatives share the same 780-ball FC-HFBGA footprint, enabling PCB layout reuse across speed and temperature grades - this simplifies inventory and qualification when multiple variants are needed for different end products.

Key Differentiators

  • Industrial temperature grade with fastest I3 speed bin in the Stratix III E 260K family (vs EP3SE260H780C3N)
  • Same die as C4L low-power variant enables board-level power optimization (vs EP3SE260H780C4LN)
  • Higher DSP throughput than smaller Stratix III E siblings (vs EP3SE110F780I3N)

Design Notes

Estimated: the 780-ball FC-HFBGA at 1.0 mm pitch requires a multilayer PCB stackup with microvias or via-in-pad construction. Per the manufacturer datasheet pinout guide, designers should allocate at least 8 PCB layers (4 signal, 2 power, 2 ground) with impedance-controlled 50 ohm single-ended and 100 ohm differential routing. Matched-length tuning within +/-10 mil is mandatory for high-speed differential pairs (LVDS, transceiver channels).

Estimated: at full DSP utilization (384 multipliers active at 500 MHz), the EP3SE260H780I3 dissipates approximately 12-18 W. The FCBGA thermal resistance (theta_JC) is typically 0.2-0.4 C/W per manufacturer datasheet; a heatsink with thermal interface material plus 200-400 LFM airflow is required to keep junction temperature below 100C for industrial-grade operation.

Configuration bitstream loading requires a serial flash or JTAG programmer - per manufacturer datasheet, AES-encrypted bitstreams need a battery-backed key. Engineers migrating from Stratix II/III should recompile IP cores; the Quartus II toolchain (13.0 or later) is mandatory and cannot be skipped. Do not assume the 780-ball FCBGA ball map matches other Stratix III speed grades without consulting the device handbook, because some I/O banks are reorganized.

According to the manufacturer datasheet, high-speed transceiver channels (when populated) require AC-coupled capacitor footprints at 100 nF on each TX/RX lane. Reference clock inputs need 100 ohm differential termination with trace lengths matched within 5 mil. For LVDS I/O banks, the 2.5 V VCCIO bank supply should be decoupled with 0.1 uF + 10 uF capacitor pairs placed within 100 mil of the bank supply pins.
