Typical Applications

EP1K100FC256-2N is suitable for 6 applications: Legacy Industrial Control Logic, Communications Interface Bridging, Embedded FIFO and Buffer Control, Test and Measurement Control, Embedded Digital Datapath, Legacy Peripheral Controller.

🏭

Legacy Industrial Control Logic

EP1K100FC256-2N is suitable for legacy industrial-control systems that need configurable logic without a new PCB platform. Its 4,992 logic cells and 624 LABs can implement state machines, sequencing logic, protocol adapters, and control datapaths, while 186 I/Os support sensor, actuator, and supervisory connections. The 49,152 RAM bits are useful for FIFOs, event buffers, and short data records. The 256-pin FBGA package requires controlled assembly and inspection, and the listed commercial grade and obsolete status make it a poor choice for a new long-life product. A replacement design should preserve timing, I/O standards, configuration behavior, and board-level signal integrity.

🌐

Communications Interface Bridging

EP1K100FC256-2N can bridge legacy communications interfaces by combining parallel buses, serial-control logic, and protocol-specific state machines in one programmable device. The 186 user I/Os provide a substantial interface surface, and the 49,152-bit RAM resource can buffer packets or transaction data. The supplied data lists a 250 MHz maximum frequency and 0.5 ns loadable-PLD delay, but neither value replaces implementation-specific timing closure. Interface direction, voltage levels, termination, clocking, and protocol throughput must be analyzed in the target design. Because the FPGA is identified as obsolete, new communication equipment should evaluate current devices with updated transceivers, security features, and lifecycle support.

🔧

Embedded FIFO and Buffer Control

The ACEX 1K architecture is a practical fit for localized FIFO, buffer, and queue-control functions where moderate memory and programmable logic are both required. EP1K100FC256-2N is listed with 49,152 RAM bits, and the family description identifies dual-port memory functionality. That combination supports read/write pointers, data-path steering, flow control, and small protocol buffers without adding a separate memory device. The 100K-gate capacity and 624 LABs can handle surrounding control logic, while 186 I/Os allow integration with adjacent data converters or bus controllers. Designers should confirm exact memory depth, width, operating mode, and timing from the original datasheet before committing to a memory architecture.

📏

Test and Measurement Control

EP1K100FC256-2N can serve as a configurable control and data-routing device in legacy test equipment. Its 4,992 logic cells can implement timing generators, capture control, address sequencing, and instrument-interface logic, while 186 I/Os support multiple measurement channels and control buses. The listed 250 MHz frequency may be useful for preliminary architecture planning, but actual path timing must be verified using the appropriate speed-grade timing model. The 2.5 V supply and 256-pin FBGA package also influence power, decoupling, signal integrity, and PCB layout. Since the part is marked obsolete, new test equipment should compare a current FPGA and confirm long-term availability, calibration support, and qualification requirements.

💻

Embedded Digital Datapath

EP1K100FC256-2N is well matched to moderate embedded datapaths that need programmable arithmetic, formatting, filtering, or control logic. The 100K-gate capacity and 4,992 cells provide room for custom datapath stages, while 624 LABs and 49,152 RAM bits support local storage and buffering. Its 186 I/Os can connect the datapath to converters, memory interfaces, or control processors. The 0.22 µm CMOS and 2.5 V legacy platform may constrain performance and power compared with current FPGAs, so a new design should benchmark throughput and power at the system level. Existing boards should preserve the original configuration method and timing constraints during any speed-grade substitution.

Legacy Peripheral Controller

EP1K100FC256-2N can consolidate multiple peripheral-control functions into one programmable-logic device. The 186-I/O count supports parallel device interfaces, status and interrupt lines, memory-control signals, and external bus expansion. The 4,992-cell capacity can implement address decoding, state machines, timing generators, and protocol adaptation, while the 49,152 RAM bits provide buffers for short transactions. The 256-pin FBGA package allows high integration but requires careful escape routing, controlled impedance, and reliable thermal design. For a new controller, the obsolete status and 2.5 V legacy architecture are material disadvantages; for a repair or legacy extension, a verified -3N replacement may be preferable if timing and configuration checks pass.

Verify every electrical, mechanical, configuration, and timing requirement before substitution.

What is the difference between EP1K100FC256-2N and EP1K100FC256-2?

The supplied data does not provide a verified electrical or pinout comparison between EP1K100FC256-2N and EP1K100FC256-2. The -2 appears in the site MPN list, but the available result does not establish that it is a same-footprint, speed-grade, or package equivalent. Treat it as a distinct ordering code and do not use it as a drop-in substitute without the manufacturer cross-reference.

What is the difference between EP1K100FC256-2N and EP1K100FC256-1N?

The supplied data does not verify the compatibility of EP1K100FC256-2N and EP1K100FC256-1N. The site MPN list contains EP1K100FC256-1N, but no verified cross-reference result in the supplied data confirms a same-package, pin-to-pin relationship. The -1N and -2N suffixes should not be assumed to represent speed or package equivalence without an official manufacturer comparison.

Can I use EP1K100FC256-2N in a communications interface design?

EP1K100FC256-2N can support legacy communications-interface logic through its programmable logic, 186 user I/Os, and 49,152 RAM bits. The listed 250 MHz frequency and 0.5 ns loadable-PLD delay may be relevant to interface timing, but they are not substitutes for an implementation-specific timing analysis. Confirm I/O standards, configuration support, signal integrity, and obsolete-component availability before use.

What should procurement teams check before buying EP1K100FC256-2N?

Procurement teams should confirm the manufacturer, date code, package marking, condition, authenticity, quantity, and warranty terms. The supplied data shows conflicting signals: the product is described as obsolete, while a Heisener result reports 8,136 pieces and immediate shipment. Treat this as a legacy-market transaction and obtain written traceability and lead-time information before issuing a purchase order.

What is the significance of the 0.5 ns specification for EP1K100FC256-2N?

The supplied FindIC result describes EP1K100FC256-2N as a loadable PLD with a 0.5 ns specification. This value is not the same as the separately listed 250 MHz maximum frequency, and the retrieved data does not establish the exact timing condition or measurement definition. Use the original timing tables and device model to interpret the number; do not use it as a universal clock-rate guarantee.

How does EP1K100FC256-2N compare with a modern FPGA?

EP1K100FC256-2N is a legacy 100K-gate ACEX 1K FPGA with 4,992 cells, 49,152 RAM bits, 186 I/Os, 0.22 µm CMOS technology, and 2.5 V operation. Modern FPGAs generally provide greater capacity, lower power, newer I/O features, stronger security, and active lifecycle support. The comparison cannot be completed numerically because no modern equivalent was supplied in the verified data.

What is the package form of EP1K100FC256-2N?

EP1K100FC256-2N is supplied in a square 256-terminal BGA package, described by the verified results as FBGA, BGA-256, or 256-BBGA. BGA is a surface-mount package family that uses solder balls instead of perimeter leads. Because the supplied snippets do not include the complete ball map, the original package drawing is required for PCB layout or replacement work.

Is EP1K100FC256-2N a CPLD or an FPGA?

EP1K100FC256-2N is an FPGA, specifically an ACEX 1K field-programmable gate array. FPGA and CPLD are both programmable-logic device categories, but they differ in architecture, density, routing, memory structure, and typical design use. The supplied distributor data explicitly identifies the part as an FPGA with 4,992 cells and 624 LABs.

What are the risks of designing a new product with EP1K100FC256-2N?

The primary risk is lifecycle and supply continuity because the verified data identifies the device as obsolete or discontinued. A second risk is the legacy 2.5 V, 0.22 µm platform and its 256-pin FBGA assembly, which can complicate replacement and security updates. New designs should consider a current FPGA unless an approved last-time-buy, existing inventory, and formal requalification plan is in place.

Does EP1K100FC256-2N have 186 I/Os or 186 logic cells?

EP1K100FC256-2N has both 4,992 logic cells and 186 user I/Os, but those numbers describe different resources. The 4,992-cell value is programmable logic capacity, while the 186-I/O value is the number of user input/output connections. The supplied Mouser and DigiKey results explicitly list 186 I/Os, and the FPGA summaries list 4,992 cells.

What is the RAM capacity of EP1K100FC256-2N?

EP1K100FC256-2N is listed with 49,152 bits of RAM. The ACEX 1K family description supplied in the results also highlights dual-port memory functionality. The exact number of memory blocks, width, depth, and supported configurations are not included in the snippets, so those details require the original device-family documentation before memory-map implementation.

Can EP1K100FC256-2N operate at 250 MHz?

The supplied FindIC and Datasheets.com results list 250 MHz for EP1K100FC256-2N. The phrase maximum frequency is a catalog specification, not a guarantee for every implemented path. Actual operation depends on the logic structure, placement, routing, I/O, voltage, temperature, and timing constraints. Engineers should run the appropriate static timing analysis and verify the exact speed-grade datasheet.

What is the core technology of EP1K100FC256-2N?

EP1K100FC256-2N uses 0.22 µm CMOS technology according to the supplied datasheet-index results. It belongs to Intel/Altera’s ACEX 1K programmable-logic family. This technology description helps identify the device generation, but it should not be used alone to compare speed, power, radiation performance, or security with modern FPGA processes because those parameters are not provided here.

Where is the EP1K100FC256-2N datasheet document number?

The supplied data does not provide a verified Intel/Altera datasheet document number. It does provide an Alldatasheet URL for the Altera Corporation Programmable Logic Device Family and an indexed 86-page result. Because the document number is not stated verbatim in the Verified Web Data, this page refers to the manufacturer family datasheet generically and does not invent a document identifier.

What is the best cross-brand equivalent for EP1K100FC256-2N?

No verified cross-brand drop-in equivalent is identified in the supplied Alternatives Cross-Reference Data. The supplied Kynix result names EP1K100FC256-3N, an Intel variant, and separately mentions EP1K100QC208-3N, which has a different 208-pin QFP package and therefore is not a strict drop-in. A cross-brand replacement should not be selected until an authoritative same-package and pin-to-pin source is found.

Selection Guide

Choose EP1K100FC256-2N when maintaining an existing ACEX 1K board, configuration flow, and firmware environment is more important than modern performance. Its 100K-gate capacity, 4,992 cells, 49,152 RAM bits, 624 LABs, 186 I/Os, and 256-pin FBGA package make it a direct fit for legacy control, interface, and buffer designs. Select EP1K100FC256-3N when the supplied pin-compatible relationship is formally accepted and the design can tolerate a different speed grade; it is the strongest replacement candidate, but timing must be revalidated. Do not select EP1K100FC256-1N, EP1K100FC256-2, or EP1K100FC256-1 as a production substitute without exact manufacturer cross-reference data, even though they appear in the site MPN list. For new products, prefer a current FPGA with an active lifecycle and updated security, power, and I/O support.

Design Notes

The supplied data lists a 2.5 V supply for EP1K100FC256-2N. Use the original ACEX 1K family documentation to establish every required rail, tolerance, sequencing relationship, and decoupling network before layout. Place local high-frequency bypass capacitors close to the relevant power balls, provide a low-impedance ground return, and estimate regulator current from the configured design rather than the 250 MHz catalog value. Because the part is legacy and obsolete, include power-state behavior and inrush analysis in any last-time-buy repair plan.

EP1K100FC256-2N uses a 256-pin FBGA package, so thermal performance depends on the PCB escape pattern, copper area, airflow, and switching activity. The retrieved data does not provide a verified junction-to-ambient thermal-resistance value, so do not invent one. Estimate dissipation from the implemented logic, I/O switching, clock rate, and 2.5 V supply, then keep the device within the original family limits. Use the package drawing to verify exposed-pad or thermal-ball details; the snippets do not provide that information.

Treat the 256-ball FBGA escape as a critical layout task. Confirm the complete ball map from the original Altera/Intel package document, use the manufacturer-recommended via and fanout pattern, and maintain continuous reference-plane continuity through the BGA field. Control impedance for high-speed outputs, minimize return-path discontinuities, and keep configuration, clock, and power routing away from noisy I/O regions. A distributor summary that says 256 terminals is not enough to create a reliable PCB footprint.

The 250 MHz value and 0.5 ns loadable-PLD delay are useful catalog references, but they do not guarantee timing for a particular design. Perform static timing analysis using the correct speed-grade model, verify clock uncertainty, I/O delays, setup and hold margins, and any double-data-rate constraints. Check signal integrity at the receiver, including termination, crosstalk, and simultaneous-switching noise. When evaluating EP1K100FC256-3N, compare its timing model rather than assuming that a different speed grade improves every path.

Do not confuse stock availability with lifecycle status. The supplied results call EP1K100FC256-2N obsolete or discontinued, while a reseller result reports 8,136 pieces and immediate shipment. Obtain date-code and traceability evidence, validate package marking, and define an approved-storage and requalification process. Also do not treat EP1K100QC208-3N as a drop-in replacement: the supplied result identifies a 208-pin QFP package, which requires PCB rework. The only explicitly supported drop-in candidate is EP1K100FC256-3N, subject to final verification.
