EPF10K20RC240-4 Visão geral

The Intel (formerly Altera) EPF10K20RC240-4 is a member of the FLEX 10K family of embedded programmable logic devices (PLDs), delivering approximately 20,000 usable gates in a 240-pin BFQFP (RQFP) exposed-pad package. The device integrates 1,152 logic elements across 144 LABs (logic array blocks) and offers 189 user I/O pins, providing system-on-a-programmable-chip (SOPC) integration in a single device. It is fabricated on a 0.42 µm CMOS process and operates from a 5 V supply with industrial 0 °C to 70 °C temperature support.

An FPGA (Field Programmable Gate Array) is a type of integrated circuit containing an array of programmable logic blocks, interconnect, and I/O cells that can be configured by the customer after manufacturing to implement arbitrary digital logic functions. FPGAs sit hierarchically below ASICs and above standard logic in flexibility-vs-cost, and the FLEX 10K family specifically pioneered embedded array blocks (EABs) for on-chip SRAM/ROM, enabling system-on-chip integration of logic plus memory in one device.

Key features of the EPF10K20RC240-4 include 12,288 typical gates, 1,152 logic elements (cells), 144 LABs, 189 user I/Os, 5 V core operation, and a 240-pin BFQFP exposed-pad package for improved thermal dissipation. The -4 speed grade corresponds to a slower timing bin than -3 but offers cost advantages for designs that do not require maximum clock rates. The exposed-pad (EP) construction provides a low thermal-resistance path to PCB copper for reliable operation up to the rated junction temperature.

Typical applications include glue logic and bus interfacing in industrial control systems, legacy telecom infrastructure, prototyping platforms for ASICs, and educational hardware where the FLEX 10K family remains widely supported by the legacy Altera MAX+PLUS II / Quartus tool flow. The 189 I/O count is well matched to peripheral-rich embedded designs.

When designing with this device, ensure adequate decoupling on all VCCINT/VCCIO pins and follow Altera's BFQFP land-pattern recommendations to avoid solder-joint fatigue. The -4 speed grade is the slowest of the FLEX 10K20 family - verify timing closure before substituting -3 or unmarked parts.

Aplicações típicas

EPF10K20RC240-4 é adequado para 6 aplicaçãos: Industrial Glue Logic and Bus Interfacing, Legacy Telecom Infrastructure, ASIC Prototyping Platform, Educational Hardware and FPGA Training, Test and Measurement Equipment Backplanes, Military and Aerospace Legacy Avionics.

🏭

Industrial Glue Logic and Bus Interfacing

The EPF10K20RC240-4 excels as glue logic between legacy microcontrollers, memory, and peripheral buses in industrial control systems. Its 189 user I/Os handle address/data multiplexing, chip-select decoding, and timing-protocol bridging in a single device, replacing dozens of 74-series logic gates. The 5 V tolerant I/Os and 0.70 C operating range align with factory-floor temperature profiles, while 1,152 logic elements provide ample headroom for state-machine-rich protocol converters (e.g., ISA-to-PCI, VME bridge logic).

🌐

Legacy Telecom Infrastructure

In telecom central-office equipment of the 1990s-2000s era, the EPF10K20RC240-4 implemented framing, line-card control, and backplane arbitration functions. Its embedded array blocks (EABs) provide on-chip dual-port SRAM for small FIFO buffers between TDM time slots, eliminating external RAM and reducing board area. The 240-BFQFP exposed-pad package is robust against the vibration and thermal cycling of telecom racks, and Altera's mature configuration bitstream toolchain (MAX+PLUS II) ensures bitstream reproducibility for decades-long field support.

🖥️

ASIC Prototyping Platform

Designers used the EPF10K20RC240-4 as an FPGA prototype before committing an ASIC to fab, validating RTL logic at near-ASIC clock rates thanks to the -3 and -4 speed grades. The 1,152 logic elements plus EAB SRAM map cleanly to standard-cell ASIC gate libraries, and Quartus II synthesis reports correlate well with ASIC synthesis timing. For digital-signal-processing or bus-protocol prototypes that will eventually migrate to a 0.18 µm ASIC, the 240-BFQFP exposed pad provides the thermal margin needed for sustained burn-in testing.

🎓

Educational Hardware and FPGA Training

University digital-design labs adopted the EPF10K20RC240-4 on Altera UP2 and similar education boards because the FLEX 10K family balances logic density, JTAG-friendly configuration, and student-friendly MAX+PLUS II GUI. The 189 I/Os expose students to buses, LEDs, seven-segment displays, and VGA/PS2 interfaces simultaneously, and the EAB SRAM teaches embedded-memory concepts. The device remains in active use at universities worldwide, and the legacy toolchain is freely downloadable for educational purposes.

📺

Test and Measurement Equipment Backplanes

Instruments such as logic analyzers, protocol testers, and modular ATE systems used the EPF10K20RC240-4 as a backplane arbiter between instrument cards. Its 189 I/Os accommodate multi-drop test buses, trigger distribution, and high-speed pattern generation, while the embedded EABs implement deep pattern-capture FIFOs. The exposed-pad 240-BFQFP package ensures reliable operation across the 0 °C to 70 °C commercial-industrial range typical of laboratory environments.

✈️

Military and Aerospace Legacy Avionics

Avionics LRUs (line-replaceable units) from the late 1990s incorporate the EPF10K20RC240-4 for MIL-STD-1553 bus termination, ARINC 429 decoding, and discrete I/O aggregation. Although not formally MIL-PRF-38535 qualified, the plastic BFQFP package has demonstrated decades-long field reliability in commercial-derivative military systems. Because avionics programs demand 20+ year sustainment, the EPF10K20RC240-4 remains in active procurement through brokers and franchised inventory for these long-life platforms.

What is the gate count of the EPF10K20RC240-4?
The EPF10K20RC240-4 has approximately 20,000 usable gates and 1,152 logic elements organized across 144 logic array blocks (LABs). According to the Altera FLEX 10K family datasheet, this places it in the mid-density tier of the FLEX 10K lineup. It is fabricated on a 0.42 µm CMOS process and targets industrial/commercial operating temperature (0 °C to 70 °C).
How many user I/O pins does the EPF10K20RC240-4 have?
The EPF10K20RC240-4 provides 189 user I/O pins in a 240-BFQFP exposed-pad package. This high I/O count is well suited for bus-intensive designs such as legacy peripheral interfaces and industrial glue logic. The exposed pad underneath the package provides a thermal dissipation path; it should be soldered to a copper pour per the manufacturer's land-pattern recommendation.
What is the difference between speed grades -3 and -4 on FLEX 10K20 devices?
The -4 speed grade is the slowest bin of the FLEX 10K20 family, while -3 is faster. Both share identical logic resources (1,152 cells, 144 LABs, 189 I/Os) and the same 240-BFQFP pinout, so they are drop-in interchangeable when timing closure permits. The -3 part allows higher clock rates but commands a price premium; -4 is typically chosen when the design is not timing-critical.
Where can I buy the EPF10K20RC240-4 today?
The EPF10K20RC240-4 is widely available as of 2026-09-11 through authorized Altera/Intel distributors including Heisener, DigiKey, Mouser, AIChipLink, and Jotrin. Heisener lists in stock at $104.66 unit price with immediate shipping. Because the part is in the obsolete/legacy FLEX 10K family, distributors and aftermarket brokers are the primary sourcing channel.
What is the lead time and price of the EPF10K20RC240-4?
As of 2026-09-11, the EPF10K20RC240-4 lists at $104.66 per unit (qty 1) on Heisener with immediate shipment (estimated delivery Feb 9 - Feb 14). DigiKey and Mouser also list stock; volume pricing falls to roughly $67-75 at qty 1000. Since this is a legacy/obsolete FLEX 10K device, pricing fluctuates with broker inventory and remaining factory stock.
Is the EPF10K20RC240-4 still in production?
The EPF10K20RC240-4 is in the obsolete/legacy lifecycle status. Intel (formerly Altera) discontinued the FLEX 10K family years ago, with the APEX 20K and Cyclone families as successors. New old stock (NOS), franchised distributor inventory, and aftermarket brokers remain the only supply sources; lead times and pricing are subject to remaining-channel availability.
What is the best drop-in replacement for the EPF10K20RC240-4?
The closest drop-in replacement within the same FLEX 10K family is the EPF10K20RC240-3, which has identical logic resources (1,152 cells, 144 LABs, 189 I/Os) and the same 240-BFQFP package but a faster -3 speed grade. The EPF10K20RC240-3N variant adds an 'N' suffix typically denoting lead-free or Pb-free finish. Both are pin-compatible and can replace the -4 part when timing closure allows.
EPF10K20RC240-4 vs EPF10K20RC240-3 - which should I choose for a new design?
Choose EPF10K20RC240-4 when your design is not timing-critical and you want the lowest unit price from remaining-channel stock. Choose EPF10K20RC240-3 when you need higher clock headroom for new logic that is more aggressive than legacy code, since -3 is one speed grade faster. Both share the 240-BFQFP pinout, so the choice is purely a speed-versus-cost trade-off within the same drop-in footprint.
Can the EPF10K20RC240-3N replace the EPF10K20RC240-4 directly?
Yes. The EPF10K20RC240-3N is pin-compatible with the EPF10K20RC240-4 in the same 240-BFQFP exposed-pad package and shares identical logic resources. The 'N' suffix generally indicates a Pb-free or lead-free finish suitable for modern RoHS assembly lines. The -3 speed grade is faster than -4, so timing closure is guaranteed; only consider the speed-grade delta if migrating a design where the -4 timing margin is intentionally tight.
Where can I download the EPF10K20RC240-4 datasheet PDF?
The official Altera FLEX 10K datasheet PDF is hosted on Alldatasheet at https://www.alldatasheet.com/datasheet-pdf/pdf/527313/ALTERA/EPF10K20RC240-4.html, with mirrored copies available on Octopart. The datasheet covers device architecture, pinout for the 240-BFQFP package, DC/AC characteristics, and configuration details. Intel's official product page is recommended for ordering information; however, for in-depth electrical specifications the Altera datasheet PDF remains the authoritative source.
Where do I find the EPF10K20RC240-4 pinout?
The EPF10K20RC240-4 pinout is documented in the Altera FLEX 10K datasheet as a 240-BFQFP exposed-pad package. The 189 user I/Os are distributed across all four sides of the QFP; the exposed pad is on the underside for thermal relief. Package drawing and pin assignments are in the datasheet's 'Package Information' and 'Pin-Out' sections. Note: the BFQFP variant uses 1.27 mm pitch with 45 × 45 mm body.
What design software supports the EPF10K20RC240-4?
The EPF10K20RC240-4 is supported by Altera's legacy MAX+PLUS II toolchain (versions up to 10.x) and Quartus II versions through roughly Quartus II 13.0. The BitBlaster or ByteBlaster download cable is used for JTAG configuration. Modern Quartus Prime editions do not include FLEX 10K support, so legacy toolchains and EDIF netlist import paths remain the primary flow.
What is the operating voltage of the EPF10K20RC240-4?
The EPF10K20RC240-4 operates from a 5 V supply (VCCINT). The I/O banks can typically be configured for 5 V or 3.3 V signaling depending on VCCIO. This is documented in the FLEX 10K datasheet's 'DC Characteristics' section. Because the device is 5 V core and supports 5 V-tolerant I/O, it is well matched to legacy TTL-level buses common in industrial and telecom equipment of the 1990s.
Is the EPF10K20RC240-4 RoHS compliant?
The original EPF10K20RC240-4 (with the 'N' suffix absent) is generally not RoHS compliant - it uses a SnPb finish typical of pre-2000 Altera packages. The EPF10K20RC240-4N variant or the 'N' designation in similar FLEX 10K parts indicates a Pb-free / RoHS-compliant finish. If your assembly line mandates RoHS, source the -4N variant explicitly and confirm finish with the supplier.

Guia de seleção

Choose EPF10K20RC240-4 when you need the original FLEX 10K20 baseline part for legacy-system sustainment, training labs, or production boards already qualified with SnPb assembly. It is the lowest-cost entry into the 1,152-cell FLEX 10K20 family. If your design requires tighter timing margins, step up to the EPF10K20RC240-3 (same package, one speed grade faster). If your assembly line requires Pb-free reflow, choose the EPF10K20RC240-4N. Avoid the EPF10K20RC208-4 unless you are intentionally redesigning for a smaller 208-pin footprint - it has only ~148 user I/Os and is NOT a true drop-in replacement despite the matching FLEX 10K20 family.

Notas de projeto

The 240-BFQFP exposed-pad package requires the central thermal pad to be soldered to a PCB copper pour of at least 1 square inch for rated operation. Estimated: at 5 V VCCINT and typical 200 mA active current, junction-to-ambient thermal resistance is roughly 25 C/W with a 1 in² 4-layer copper pour, supporting 0 °C to 70 °C operation at moderate toggle rates. Without the EP soldered, internal junction temperatures may exceed 100 °C during continuous operation.

Place 0.1 µF decoupling capacitors within 5 mm of every VCCINT and VCCIO pin pair, plus bulk 10 µF tantalum capacitors at each supply rail entry point. The 240-BFQFP package has 1.27 mm pitch - route signals on inner layers to avoid crosstalk on long outer-layer traces. Follow Altera's recommended 4-layer stack-up with continuous ground plane beneath the device to control return-path impedance for the JTAG configuration signals (TCK, TMS, TDI, TDO).

Critical pitfalls when migrating between FLEX 10K20 speed grades: (1) verify that the -3 part's improved timing margin is genuine for your specific design paths, not just nominal; (2) the 'N' suffix denotes Pb-free finish and is electrically identical but may have different reflow-profile requirements (peak 260 °C vs 220 °C); (3) configuration bitstreams are speed-grade-dependent - do not use a -3 bitstream on a -4 device without resynthesis; (4) JTAG chain order matters when programming multiple devices via ByteBlaster.
