EP20K400FI672-3N Overview
A field-programmable gate array, or FPGA, is a semiconductor device containing programmable logic elements, routing resources, and configurable input/output cells. FPGA architecture sits within the broader hierarchy of programmable logic, then digital logic ICs, integrated circuits, and semiconductors. Unlike a fixed-function application-specific integrated circuit, an FPGA can be configured after manufacturing, allowing designers to implement changing logic requirements without producing a new custom mask set.
The EP20K400FI672-3N combines a 2.5 V nominal operating point with a 2.375 V to 2.625 V supply range. Its 502 I/O lines make the device relevant to systems that need many parallel connections or several external bus interfaces. The 3.6 ns propagation delay and 833 MHz maximum clock frequency are important timing indicators, although actual design performance depends on the selected configuration, routing, I/O standards, load, and power conditions.
The device is built using CMOS technology and is offered in a 672-terminal PBGA package identified as S-PBGA-B672, with 1.000 mm terminal pitch. This high-pin-count package supports the device's extensive I/O capability but requires careful BGA assembly, escape routing, power distribution, and thermal analysis. The large number of terminals also makes footprint verification essential when considering a replacement.
Typical applications include telecommunications interface equipment, industrial control and automation, and high-density digital processing platforms. It can serve as configurable glue logic, protocol or bus bridging infrastructure, or an integration layer for multiple peripheral interfaces. The exact architecture, logic capacity, configuration method, supported I/O standards, and operating-temperature grade are not present in the supplied verified data and require the manufacturer documentation before final design approval.
For design-in, verify the complete pin assignment, required supply rails, decoupling network, configuration interface, and timing constraints against the official manufacturer datasheet. A proposed replacement must match the 672-terminal PBGA footprint and pinout as well as the relevant electrical and timing parameters. This page combines the supplied distributor and manufacturer-source findings with clearly marked data gaps and does not infer unverified specifications.

Typical Applications
EP20K400FI672-3N is suitable for 6 applications: Industrial Automation Controllers, Telecommunications Interface Equipment, High-Density Digital Backplanes, Test and Measurement Instrumentation, Communication Protocol Bridging, Legacy System Maintenance and Control.
Industrial Automation Controllers
EP20K400FI672-3N can be evaluated for industrial automation controllers that require configurable logic and a large number of external connections. Its verified 502 I/O lines can aggregate sensor inputs, actuator controls, status signals, and inter-module buses without immediately expanding into multiple programmable devices. The 2.5 V nominal supply and 2.375 V to 2.625 V range provide a defined power target, while the 3.6 ns propagation-delay value and 833 MHz maximum clock frequency help establish an initial timing budget. The device should be positioned as a configurable control and interface-integration component rather than a fixed-function controller. Before design approval, confirm operating temperature, I/O standards, logic capacity, configuration method, and available development tools from the manufacturer documentation. For a new industrial platform, also verify whether the 672-terminal PBGA can be assembled with the intended process and whether a lifecycle supply agreement is available.
Recommended
Telecommunications Interface Equipment
EP20K400FI672-3N is potentially useful in telecommunications interface equipment where parallel data paths, control channels, and protocol conversion are combined in one programmable logic device. The verified 502 I/O lines can support numerous physical and logical connections, while the 3.6 ns propagation-delay specification helps identify devices requiring careful timing closure. The 2.5 V nominal supply range of 2.375 V to 2.625 V must be implemented with a low-noise regulator and local decoupling appropriate to the documented rail requirements. Because the supplied data does not identify supported I/O standards, serializer/deserializer resources, logic capacity, or transceiver capability, those features must not be assumed. The 672-terminal S-PBGA-B672 package also demands controlled impedance, complete ball-map review, and high-density assembly capability. A timing analysis should use the exact configuration and interface constraints, not the 833 MHz maximum alone.
Recommended
High-Density Digital Backplanes
EP20K400FI672-3N can serve as a configurable bridge or aggregation device in a high-density digital backplane. Its 502 verified I/O lines are a strong fit for systems combining many parallel bus segments, control signals, and status monitoring paths. The APEX 20K architecture allows system logic to be adapted when interface requirements change, but the supplied evidence does not quantify the device's logic resources or supported I/O standards, so capacity planning remains incomplete. The 2.5 V nominal supply and 1.000 mm BGA pitch must be incorporated into the power and PCB design from the beginning. A 672-terminal package requires a verified land pattern, escape strategy, and signal-integrity review for high-speed or heavily loaded nets. Use the official datasheet to confirm pin multiplexing, configuration pins, clocking resources, and timing constraints before treating this device as a backplane bridge.
Recommended
Test and Measurement Instrumentation
EP20K400FI672-3N may be considered for test and measurement equipment that needs configurable timing, control, and signal-routing logic. The verified 3.6 ns propagation delay and 833 MHz maximum clock frequency provide concrete timing landmarks for preliminary system planning, while 502 I/O lines can support instrument buses, trigger networks, control paths, and acquisition interfaces. The 2.5 V nominal supply requires a stable power implementation within the verified 2.375 V to 2.625 V range. The device's suitability for a particular measurement channel cannot be established from the supplied data because resolution, analog-interface functions, logic capacity, I/O standards, and operating-temperature specifications are not provided. Designers should use the manufacturer timing model and development-tool documentation to verify whether the selected configuration can meet measurement repeatability and synchronization requirements. Pinout accuracy is especially important because the 672-terminal S-PBGA-B672 package leaves no room for incorrect signal assignment.
Recommended
Communication Protocol Bridging
EP20K400FI672-3N is a candidate for communication protocol bridging when several control or data interfaces must be adapted within one programmable platform. Its 502 I/O lines can support multiple parallel interfaces, and the APEX 20K programmable architecture can be configured for protocol conversion, bus adaptation, or custom control sequencing. The verified 2.5 V nominal supply and 2.375 V to 2.625 V range define the power input target. However, the supplied data does not state which I/O voltage levels, termination schemes, logic resources, or interface protocols are supported, so a protocol-specific claim would be unsupported. The 3.6 ns propagation-delay value and 833 MHz maximum clock frequency should be treated as starting points for timing analysis rather than application guarantees. Confirm the complete manufacturer pinout, configuration process, toolchain, and signal-integrity requirements before implementing a bridge on a new PCB.
Recommended
Legacy System Maintenance and Control
EP20K400FI672-3N may be used in legacy system maintenance where an existing Altera APEX 20K design must be reproduced, repaired, or supported. The verified 3.6 ns propagation delay, 2.5 V nominal supply, 502 I/O lines, and 833 MHz maximum clock frequency provide a documented starting point for identifying the original device characteristics. The 672-terminal S-PBGA-B672 package and 1.000 mm pitch make physical replacement especially sensitive to land-pattern and ball-map errors. Because lifecycle status is not explicitly stated, procurement should not assume active production or long-term availability. The manufacturer data should be checked for ordering-code suffixes, speed grades, configuration compatibility, and development-tool support. For legacy boards, inspect the original bill of materials, approved-vendor list, and date-code requirements before authorizing a substitute. A replacement with a different APEX 20K ordering code is not a drop-in choice without a complete pinout and timing comparison.

- Defined propagation-delay value (vs EP20K400EFC672-3N)
Design Notes
Before routing, obtain the official 672-terminal S-PBGA-B672 ball map and recommended land pattern. The verified package description establishes the terminal count and 1.000 mm pitch but does not provide ball functions, power pins, configuration pins, or differential-pair assignments. Verify escape routing, via dimensions, solder-mask definition, and the assembly process with the PCB fabricator. Do not generate a pinout from the package silhouette or a distributor photo.
Design the nominal 2.5 V rail to remain inside the verified 2.375 V to 2.625 V range under transient, load, and temperature conditions. The supplied data does not identify the number of rails, regulator-current requirement, permitted ripple, or decoupling values, so those values must come from the manufacturer datasheet. Place the regulator and local bypass network close to the relevant power entry and power pins, and keep high-current return paths away from sensitive clock and configuration traces.
Treat 3.6 ns propagation delay and 833 MHz maximum clock frequency as preliminary timing indicators only. Actual system timing depends on the implemented logic, routing, I/O loading, voltage, temperature, and configuration. Use the official timing model to constrain clocks, establish setup and hold margins, and model output behavior. The supplied data does not identify supported I/O standards or termination requirements, so those values must not be guessed.
The 672-terminal BGA can make thermal verification important, but the supplied data does not provide junction-temperature limits, thermal resistance, or power dissipation. Do not estimate a safe power level without the manufacturer thermal model and the intended airflow, PCB copper, and via arrangement. Use the official thermal documentation to calculate junction temperature and verify that the selected package and board implementation provide adequate heat spreading.
Compliance Information
The supplied verified data does not state RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals compliance. Obtain the manufacturer declaration before making a compliance claim.
