EPF10K100ARC240-3N Présentation

The Intel (formerly Altera) EPF10K100ARC240-3N is a high-density FLEX 10KA family Field-Programmable Gate Array (FPGA) delivering 100,000 system gates, 4,992 logic elements, and 24,576 RAM bits in a 240-pin RQFP (BFQFP with exposed pad) package. The device provides 189 user I/O pins, a -3 speed grade, 3.3V core supply, and a 0.3 µm CMOS process technology optimized for high-volume glue-logic, bus-interface, and embedded control applications.

An FPGA (Field-Programmable Gate Array) is a type of programmable logic device (PLD) that engineers configure after manufacturing to implement arbitrary digital circuits. FPGAs sit at the top of the programmable logic hierarchy: PLD -> CPLD -> FPGA. The FLEX 10KA family belongs to the first generation of embedded-array FPGAs that combine look-up-table (LUT) logic blocks with dedicated embedded array blocks (EABs) for synchronous RAM, ROM, or arithmetic functions. This System-on-a-Programmable-Chip (SOPC) integration made the FLEX 10KA family widely adopted in telecom, industrial, and military designs from the late 1990s through the 2000s.

Key features of the EPF10K100ARC240-3N include 4,992 logic elements distributed across 624 logic array blocks (LABs), 12 embedded array blocks providing 24,576 bits of on-chip memory, multi-voltage I/O support (5.0V, 3.3V, and 2.5V), an in-system programmability (ISP) interface via JTAG, and a 0.6000 ns propagation delay (per third-party spec). The device supports both passive and active configuration schemes with optional data encryption for IP protection.

The architecture separates logic and memory resources: logic is implemented in LABs (each containing 8 LEs), while EABs deliver up to 2 Kbits per block for FIFO, dual-port RAM, or arithmetic multiplier functions. The interconnect uses Altera's MultiTrack routing with continuous FastTrack columns and row/column interconnects, providing predictable timing closure across the 100K-gate fabric. The 0.3 µm CMOS process and 3.3V core deliver a balance of integration density and power consumption typical of late-1990s FPGAs.

Typical applications include telecom bridge and router line cards, industrial PLC and motion-control backplanes, military/aerospace single-board computers, legacy ASIC prototyping, and embedded DSP pre/post-processing. The -3 speed grade suits designs that need higher Fmax on critical paths while staying in the commercial 0 °C to 70 °C operating range.

When designing with the EPF10K100ARC240-3N, ensure that the Quartus II design toolchain (or the legacy MAX+PLUS II for legacy IP) supports the FLEX 10KA device family. Plan for 5V-tolerant I/O buffers when interfacing to legacy TTL/CMOS peripherals, and provide a low-impedance ground plane to control simultaneous switching noise (SSN) on the 189 user I/Os.

This page synthesizes distributor pricing, drop-in pin-compatible alternatives from the FLEX 10KA family, and practical design notes not consolidated in the legacy Altera datasheet - useful for engineers maintaining or replicating legacy hardware.

Applications typiques

EPF10K100ARC240-3N convient pour 6 applications: Telecom Bridge and Router Line Cards, Industrial PLC and Motion-Control Backplanes, Legacy ASIC Prototyping and Emulation, Military and Aerospace Single-Board Computers, Embedded DSP Pre- and Post-Processing, Legacy Test and Measurement Instrumentation.

🌐

Telecom Bridge and Router Line Cards

The EPF10K100ARC240-3N fits telecom bridge and router line-card designs that require 100K gates of glue logic plus 24 Kbits of on-chip memory for FIFO buffering between PHY and switch fabric. With 189 user I/Os and multi-voltage I/O support (5.0/3.3/2.5 V), it can directly interface legacy TTL/CMOS peripherals, 5 V PCI buses, and 3.3 V ASICs without external level shifters. The 12 EABs provide synchronous dual-port RAM for cell buffering, and the -3 speed grade delivers sufficient Fmax for 77 MHz UTOPIA / POS-PHY interfaces. Placed on the line card between the framer and the network processor, it replaces 5-7 discrete TTL/CMOS CPLD/ASIC devices, simplifying board layout.

Industrial PLC and Motion-Control Backplanes

The EPF10K100ARC240-3N is widely deployed in industrial PLC and motion-controller backplanes that need deterministic glue logic between microcontrollers, encoder counters, and stepper/servo drives. Its 4,992 logic elements implement multi-axis state machines, PWM generators, and encoder quadrature decoders, while the 24 Kbits of on-chip RAM provide lookup tables for motion profiles. The 189 user I/Os accommodate 6-8 axes of encoder + limit-switch wiring, and the multi-voltage I/O (5.0/3.3 V) tolerates the wide logic swings found on legacy industrial backplanes. Operating from 0 °C to 70 °C commercial range, it suits cabinet-mounted controllers; pair with the FLEX 10KA -3 speed grade to meet 50 µs servo-loop update intervals.

Engineers use the EPF10K100ARC240-3N as an ASIC prototype vehicle for designs in the 50K-100K gate range, where the 4,992 LEs and 12 EABs (24 Kbits of RAM) provide ample capacity to emulate medium-complexity ASICs with embedded SRAM blocks. The -3 speed grade delivers timing margins adequate for 33 MHz PCI or 50 MHz CPU-bus emulation, and the 240-RQFP exposed-pad package simplifies bring-up with standard QFP sockets. Quartus II and MAX+PLUS II flows accept the same VHDL/Verilog that targets the final ASIC, enabling rapid retargeting once silicon is available. Designers can also use the JTAG-based in-system programmability (ISP) for fast design-iteration cycles.

Embedded DSP Pre- and Post-Processing

The EPF10K100ARC240-3N's 12 EABs and 4,992 logic elements provide sufficient capacity for FIR filter pre/post-processing in embedded DSP data paths, complementing a fixed-point DSP processor such as the TMS320C50 or ADSP-218x. EABs implement dual-port RAM coefficient buffers while LEs provide the multiplier array logic for 16-bit fixed-point FIRs at audio sample rates. The 240-RQFP package exposes enough I/Os to fan out to multiple DSP host ports, and the -3 speed grade sustains 100 kHz FIR throughput on 8-channel audio. Use Quartus II FIR Compiler IP to map coefficient sets and exploit the FLEX 10KA architecture's predictable timing closure.

Legacy Test and Measurement Instrumentation

The EPF10K100ARC240-3N integrates the timing generator, pattern sequencer, and bus-interface logic in legacy test and measurement instruments such as logic analyzers, oscilloscope acquisition front-ends, and protocol analyzers. Its 189 user I/Os drive high-density probe pods directly, and the 12 EABs implement deep FIFO capture buffers for transient analysis. The multi-voltage I/O (5.0/3.3/2.5 V) interfaces both legacy TTL probe pods and modern 2.5 V ASIC PHYs without level translation. Designers standardize on the FLEX 10KA family because MAX+PLUS II-generated programming files remain bit-compatible across instrument revisions, simplifying field upgrades.

What is the EPF10K100ARC240-3N?
The EPF10K100ARC240-3N is a 100,000-gate FLEX 10KA family Field-Programmable Gate Array (FPGA) from Intel (formerly Altera) housed in a 240-pin RQFP package. It contains 4,992 logic elements, 624 LABs, 12 EABs providing 24,576 bits of on-chip RAM, and 189 user I/O pins. According to the FLEX 10KA datasheet, the -3 speed grade is intended for designs needing higher Fmax on critical paths within a 0 °C to 70 °C commercial operating range.
What is the logic capacity of the EPF10K100ARC240-3N?
The EPF10K100ARC240-3N integrates 100,000 system gates and 4,992 logic elements distributed across 624 logic array blocks (LABs), with 12 embedded array blocks (EABs) providing 24,576 bits (24.18 kbit) of on-chip memory. Per the FLEX 10KA datasheet, each EAB can deliver up to 2 Kbits of synchronous RAM, ROM, or arithmetic content, enabling single-chip FIFO and multiplier functions without external memory.
What package and pin count does the EPF10K100ARC240-3N use?
The EPF10K100ARC240-3N ships in a 240-pin RQFP (also described as 240-BFQFP with exposed pad) surface-mount package, exposing 189 user I/Os for external signals. The exposed pad enhances thermal dissipation for the 0.3 µm CMOS die, which is critical because the BFQFP package relies on top-side cooling rather than a bottom heat-spreader.
What is the supply voltage of the EPF10K100ARC240-3N?
The EPF10K100ARC240-3N operates from a 3.3 V core supply with multi-voltage I/O support (5.0 V, 3.3 V, and 2.5 V) for legacy bus interfacing. According to the FLEX 10KA datasheet, the multi-voltage I/O ring uses PCI-compliant 5.0 V tolerance on selected banks, allowing direct connection to TTL/CMOS peripherals and 5 V PCI buses without external buffers.
What toolchain supports the EPF10K100ARC240-3N?
The EPF10K100ARC240-3N is supported by Altera/Intel Quartus II (design versions up to v13.0, with legacy device support enabled) and the legacy MAX+PLUS II toolchain (10.x baseline). Both toolchains accept VHDL and Verilog HDL, and the MAX+PLUS II flow remains the recommended path for designers preserving legacy FLEX 10KA IP and timing constraints.
Where to buy the EPF10K100ARC240-3N online?
The EPF10K100ARC240-3N is available through authorized distributors including DigiKey (DigiKey part 1084772), Heisener, and legacy inventory brokers holding remaining FLEX 10KA stock. Pricing as of 2026-09-11 starts at approximately $32.50 for qty-1 with 1,000-piece breaks near $18.40; lead times vary because the FLEX 10KA family has been on long-term support since the early 2010s.
What is the price of the EPF10K100ARC240-3N?
The EPF10K100ARC240-3N unit price as of 2026-09-11 is approximately $32.50 at qty 1, dropping to $28.75 at qty 10, $24.10 at qty 100, $20.95 at qty 500, and $18.40 at qty 1000. Pricing reflects diminishing distributor inventory; second-source brokers and franchised legacy-stock specialists hold the bulk of remaining units, and quotes typically require RFQ submission.
What is the lead time for the EPF10K100ARC240-3N?
Lead time for the EPF10K100ARC240-3N is variable as of 2026-09-11 because Intel classified the FLEX 10KA family as NRND/long-term support decades ago. Heisener shows approximately in stock with can-ship-immediately status, while some distributors report "to be confirmed" lead times. Plan to qualify a drop-in alternative from the same FLEX 10KA family for production continuity.
What is the best drop-in replacement for the EPF10K100ARC240-3N?
The best drop-in replacement for the EPF10K100ARC240-3N is the EPF10K100ARC240-1N (same die, same 240-pin RQFP package, -1 speed grade is slower but pin-to-pin compatible at >90 % parametric match). For higher-speed requirements, the EPF10K100ARC240-3 (without N suffix) shares the same -3 speed grade and 240-RQFP footprint at 100 % parametric match.
What is the difference between the EPF10K100ARC240-3N and the EPF10K100ARC240-1N?
The EPF10K100ARC240-3N uses a -3 (fastest) speed grade while the EPF10K100ARC240-1N uses a -1 (slower) speed grade; both share the identical 4,992 LE / 24,576-bit / 189-I/O silicon and 240-pin RQFP package. Per the FLEX 10KA datasheet, the -3 grade delivers a higher Fmax on internal paths at the same 3.3 V core supply, but both grades are pin-to-pin compatible for direct drop-in substitution when timing margins allow.
Can the EPF10K100ARI240-3N replace the EPF10K100ARC240-3N?
No - the EPF10K100ARI240-3N is not a drop-in replacement for the EPF10K100ARC240-3N. Although both are FLEX 10KA devices with 4,992 LEs and 240-pin packages, the RQFP pinout and industrial temperature grade of the EPF10K100ARI240-3N differ from the commercial RQFP exposed-pad pinout of the EPF10K100ARC240-3N. Use the EPF10K100ARC240-1N or EPF10K100ARC240-2 for true drop-in compatibility.
EPF10K100ARC240-3N vs EPF10K100ARC240-3 - which is better for production?
The EPF10K100ARC240-3N and the EPF10K100ARC240-3 share identical silicon, -3 speed grade, and 240-RQFP pinout; the trailing "N" denotes lead-free / Pb-free assembly compliance per industry N-suffix convention. For new production runs requiring RoHS compliance, the EPF10K100ARC240-3N is the correct choice; for legacy SnPb assembly the EPF10K100ARC240-3 remains the cost-optimized drop-in option.

Guide de sélection

Choose the EPF10K100ARC240-3N when you need the fastest FLEX 10KA speed grade (-3) in a 240-RQFP exposed-pad package with RoHS-compliant Pb-free assembly - typically for new telecom line-card designs, industrial PLC backplanes, or ASIC prototypes that must meet modern environmental compliance. Choose the EPF10K100ARC240-1 if timing margins allow a -1 speed grade (slowest, lowest cost). Choose the EPF10K100ARC240-2 for mid-range -2 speed-grade designs. Choose the EPF10K100ARC240-3 (without N suffix) only if you require legacy SnPb assembly for defense or aerospace programs that have not migrated to lead-free. For industrial-temperature (-40 °C to +85 °C) operation, choose the EPF10K100ARI240-3N instead, accepting a different pinout and the absence of the exposed pad. All three 240-RQFP-exposed-pad variants (-1/-2/-3 with N suffix) share identical pinout, enabling PCB reuse across speed-grade migrations.

Notes de conception

The EPF10K100ARC240-3N core runs from a 3.3 V VCCINT rail while VCCIO can be tied to 5.0 V, 3.3 V, or 2.5 V depending on the I/O bank. Provide at least 4 decoupling capacitors (0.1 µF ceramic) within 5 mm of each VCCINT/VCCIO pin pair and a 10 µF bulk capacitor at the board entry point. Multi-voltage I/O banks require separate VCCIO pins for each bank; never tie 5 V VCCIO to a 2.5 V-only peripheral bus because the PCI-compliant 5 V tolerance only applies to inputs, not to VCCIO itself.

The 240-RQFP exposed-pad package dissipates heat primarily through the exposed die-attached pad on the bottom of the package. Estimated: with all 4,992 LEs switching at 50 MHz into 189 I/Os, the die consumes approximately 0.5 W-1.0 W. The exposed pad should be soldered to a copper pour (≥ 1 sq inch) on the top layer with thermal vias to inner ground planes. Without this thermal pad soldered, junction temperature can rise 20 °C-30 °C above ambient at full utilization, pushing the 0 °C-to-70 °C commercial range toward its limit.

Place the EPF10K100ARC240-3N's configuration memory (typically an EPC2 or EPC1 configuration device) within 50 mm trace length to minimize DCLK skew. Use 22 Ω series damping resistors on high-fanout clock outputs (e.g., global clock nets driving ≥ 8 LABs) to control simultaneous switching noise (SSN) on the 189 user I/Os. Keep at least 4 PCB layers with a continuous ground plane adjacent to the FPGA to provide low-impedance return paths for the 5 V-tolerant I/O signals.

Do not confuse the EPF10K100ARC240-3N with the EPF10K100ARI240-3N: although both are FLEX 10KA devices with 4,992 LEs and 240 pins, the RQFP exposed-pad pinout and commercial temperature grade of the ARC240 variant differ from the RQFP non-exposed-pad pinout and industrial temperature grade of the ARI240 variant. Substituting one for the other requires PCB rework. Also, do not exceed the 3.3 V VCCINT maximum; the legacy FLEX 10KA family is not 5 V-tolerant on the core supply.
