EPF6024AQC240-3N Tóm tắt

The Intel (Altera) EPF6024AQC240-3N is a member of the FLEX 6000 programmable logic device family, delivering 24,000 gates and 1,960 logic cells in a 240-pin Plastic Quad Flat Pack (PQFP) package. It features 199 user I/Os, a 3.3V core supply, and a maximum clock frequency of 133 MHz, manufactured on a 0.42 µm CMOS process with the OptiFLEX architecture that minimizes die size while preserving high performance and signal routability.

A Field-Programmable Gate Array (FPGA) is a type of programmable logic device (PLD) that allows designers to implement custom digital circuits through configuration of an array of logic blocks, embedded memory, and programmable interconnect. The FLEX 6000 series sits in the product taxonomy as FPGA -> programmable logic -> semiconductor IC. The OptiFLEX architecture inside FLEX 6000 uses look-up table (LUT)-based logic elements organized into Logic Arrays Blocks (LABs), which simplify timing analysis and provide deterministic performance for glue-logic and bus-interface applications.

Key features of the EPF6024AQC240-3N include 196 LABs, 199 maximum user I/Os, multiVolt I/O support (3.3V and 5.0V tolerant outputs with appropriate pull-ups), 5.0V CMOS input compatibility when VCCIO is tied to 3.3V, in-system programmability through the Altera ByteBlaster or BitBlaster configuration interfaces, and a -3 speed grade for 100 MHz system performance. The PQFP-240 footprint supports surface-mount assembly with standard JEDEC-compliant handling.

From an architectural standpoint, the device integrates each logic element as a 4-input LUT with a programmable register, and each LAB groups 16 logic elements with control signals for fast carry chains and cascade chains. The interconnect is a continuous, fast-path routing network with low-skew clock distribution, enabling predictable timing closure at the rated 133 MHz fmax. The configuration memory is SRAM-based, requiring external configuration storage on every power-up.

Typical applications include industrial control glue logic, telecom interface bridging, peripheral bus arbitration, legacy ASIC replacement, prototyping of custom gate arrays, and high-volume cost-sensitive designs where the FLEX 6000 family targets gate-array price points. The wide I/O count also makes the part suitable for memory-mapped interfaces between microprocessors and peripherals.

When designing with this FPGA, ensure that the configuration device (e.g., EPC2 or compatible serial EEPROM) is properly selected for SRAM-based FLEX 6000 devices, and verify that the JTAG chain includes the EPF6024AQC240-3N for boundary-scan testing. Designers migrating to newer Intel/Altera Cyclone families must consider that the FLEX 6000 is a legacy product and should plan for long-term availability before committing to new designs.

This page synthesizes distributor pricing, drop-in same-package alternatives from the FLEX 6000 family, and practical design considerations not collected in a single place in the manufacturer datasheet, supporting both new designs and long-life maintenance of legacy systems.

Ứng dụng tiêu biểu

EPF6024AQC240-3N phù hợp cho 6 Áp dụngs: Industrial Glue Logic, Telecom Interface Bridging, Legacy ASIC Replacement, Peripheral Bus Arbitration, Prototyping Custom Gate Arrays, Test & Measurement Instrumentation.

🏭

Industrial Glue Logic

The EPF6024AQC240-3N provides 24K gates of glue logic with 199 user I/Os, fitting it for interfacing microprocessors to peripheral ICs in industrial controllers. Its 3.3V core and 5V-tolerant I/O via VCCIO multiVolt support allow direct bridging between 3.3V MCUs and 5V legacy peripherals without external level shifters. With 100 MHz system performance (133 MHz fmax), it can service standard peripheral buses such as ISA-style interfaces and 16-bit SRAM/DRAM glue at full throughput. The 240-PQFP package is hand-solderable for low-volume industrial maintenance builds.

🌐

Telecom Interface Bridging

The EPF6024AQC240-3N serves as a bridge between telecom backplane buses (e.g., H.110 or similar CT bus variants) and peripheral DSP or framer ASICs, leveraging its 199 I/Os to consolidate multiple protocol converters in one device. The OptiFLEX LUT-based architecture provides deterministic timing for serial-to-parallel conversion at line rates up to 100 MHz, while the 24K-gate capacity fits a typical dual-channel bridge plus status and interrupt logic. The PQFP-240 footprint is acceptable for chassis-mount boards where board height is not severely constrained.

🔧

Legacy ASIC Replacement

For cost-sensitive products where the original ASIC has gone EOL, the EPF6024AQC240-3N offers 24K gates of reconfigurable logic with the same I/O count and footprint as the original 240-PQFP package, minimizing board rework. Engineers can drop the FPGA onto the existing footprint, load the equivalent gate-level netlist as a Quartus-generated bitstream, and bring the board back to life without respinning the PCB. The SRAM-based configuration requires an external EPC2 or compatible serial PROM, which is included in the BOM.

🖥️

Peripheral Bus Arbitration

The EPF6024AQC240-3N provides bus arbitration and DMA control for multi-master microprocessor systems, using its 199 I/Os to fan out grant/req signals and side-band controls. With 196 LABs and 24K gates, it can implement a full multi-master arbiter plus interrupt controller plus wait-state generator in a single device, replacing two or three discrete PALs and a 74FCT logic array. The 3.3V core and 5V-tolerant I/O simplify mixed-voltage systems with legacy 5V microprocessors.

✈️

Prototyping Custom Gate Arrays

The EPF6024AQC240-3N serves as a low-cost prototype vehicle for designers evaluating whether their logic would fit in a 24K-gate gate array, with the OptiFLEX architecture providing LUT-based logic that maps closely to gate-array primitives. Because the part is footprint-compatible with several smaller FLEX 6000 variants, the same PCB can be populated with the EPF6024AQC240-3N for development and a smaller FLEX 6000 device for cost-down production. This shortens time-to-prototype by weeks.

🎥

Test & Measurement Instrumentation

The EPF6024AQC240-3N is used in test fixtures and ATE for protocol generation, pattern matching, and timing-edge placement, exploiting its 133 MHz fmax and 199 I/Os to drive and observe wide parallel test buses. Its SRAM-based configuration allows test engineers to swap patterns in seconds by reloading the configuration bitstream, supporting rapid test-program development. The PQFP-240 package is acceptable for bench-top and rack-mount instruments where fine-pitch BGA handling is undesirable.

What is the EPF6024AQC240-3N and what family does it belong to?

Stock fluctuates as remaining factory lots are consumed.
EPF6024AQC240-3N vs EPF6024AQC240-2 - which is faster?
The EPF6024AQC240-3N (speed grade -3) is faster than the EPF6024AQC240-2 (speed grade -2). The -3 grade targets 100 MHz system performance and reaches 133 MHz fmax, while the -2 grade targets 80-90 MHz. Both share the same 240-pin PQFP package and the same OptiFLEX die, so the choice is a direct speed-versus-cost trade-off within the same footprint.
What is the best drop-in replacement for the EPF6024AQC240-3N?
The best drop-in replacement for the EPF6024AQC240-3N in the same 240-pin PQFP package is the EPF6024AQC240-2N (speed grade -2, same package, same die). It is pin-to-pin compatible with identical I/O and configuration pins, with the only difference being a slightly lower fmax - the firmware, configuration bitstream family, and PCB layout are unchanged.
Can the EPF6024AQC208-3N replace the EPF6024AQC240-3N directly?
No, the EPF6024AQC208-3N cannot directly replace the EPF6024AQC240-3N because the two parts use different packages (208-pin vs 240-pin PQFP). The PCB land patterns differ and pin assignments do not map 1:1, so a board redesign is required - it is not a drop-in swap.
When should I choose EPF6024AQC240-3N over a newer Cyclone FPGA?
Choose the EPF6024AQC240-3N only when maintaining a legacy design whose firmware, configuration bitstream, and PCB layout are already proven in production. For new designs, modern Intel Cyclone IV or Cyclone 10 LP families deliver higher logic density, lower power, and longer lifecycles at comparable or lower cost. The -3N is essentially a maintenance part today.
Where to download the EPF6024AQC240-3N datasheet PDF?
The EPF6024AQC240-3N datasheet PDF is available from Alldatasheet at https://www.alldatasheet.com/datasheet-pdf/pdf/527330/ALTERA/EPF6024AQC240-3N.html, and the FLEX 6000 family datasheet is mirrored on alterasemi.com. The Alldatasheet copy is a 52-page document covering the entire FLEX 6000 family, of which EPF6024AQC240-3N is one member.
Where to find the EPF6024AQC240-3N pinout diagram?
The pinout for the EPF6024AQC240-3N is published in the FLEX 6000 datasheet referenced by Alldatasheet, on pages covering the 240-pin PQFP package option. Mouser and DigiKey product pages also display a simplified pin map; the official PDF pinout is the authoritative source for board layout and signal assignment.
Is the EPF6024AQC240-3N the same as EPF6024AQC240-3?
The EPF6024AQC240-3N and EPF6024AQC240-3 share the same Altera FLEX 6000 die and the same 240-pin PQFP package, but the suffix 'N' typically indicates a lead-free / RoHS-compliant terminal finish versus a leaded finish. Pin-to-pin compatibility is preserved, and the configuration bitstream is identical, so the two are electrically interchangeable on a properly finished board.
What are the key specifications of the EPF6024AQC240-3N that engineers should know?
The EPF6024AQC240-3N provides 24,000 gates, 1,960 logic cells, 196 LABs, 199 user I/Os, a 3.3V core supply, and 133 MHz fmax at speed grade -3. According to the FLEX 6000 datasheet cited on Alldatasheet, the device is built on a 0.42 µm CMOS process using the OptiFLEX LUT-based architecture and is housed in a 240-pin Plastic Quad Flat Pack.

Hướng dẫn chọn lựa

Choose the EPF6024AQC240-3N when you need the fastest member of the 240-PQFP FLEX 6000 family (133 MHz fmax, speed grade -3) and your design is already laid out for this footprint. For cost-down production runs that do not require full speed, drop to the EPF6024AQC240-2N (90 MHz) or EPF6024AQC240-1N (60 MHz) - all share the same bitstream family and pinout, so firmware transfers without change. If you need a leaded finish (for non-RoHS markets), use the EPF6024AQC240-3 without the N suffix. The EPF6024AQC240-2S variant is an option when specific burn-in or screening is required. Avoid migrating to the 208-pin PQFP FLEX 6000 parts (e.g., EPF6024AQC208-3N) without board rework, since the pin counts and pinouts differ. For brand-new designs, consider modern Intel Cyclone IV or Cyclone 10 LP families instead, which are still active and offer higher density at lower power.

Ghi chú thiết kế

The EPF6024AQC240-3N requires both a 3.3V VCCINT core supply and a separate VCCIO supply per I/O bank. Decouple each VCCINT pin with a 0.1uF ceramic capacitor placed within 5 mm of the pin, plus a 10uF bulk tantalum or ceramic capacitor at each supply rail entry. For multi-bank designs, distribute at least one 0.1uF cap per VCCIO pin. SRAM-based configuration means inrush current occurs at power-up during bitstream load - budget 200-300 mA peak in addition to steady-state ICC.

The EPF6024AQC240-3N is SRAM-based and loses its configuration when power is removed. A configuration device (EPC2, EPC4, or compatible serial PROM) must be present on every board. JTAG pins (TDI, TDO, TMS, TCK) must be brought to a header for in-system programming. Do not leave nCONFIG, nSTATUS, or CONF_DONE floating - tie them to VCC through 10 kohm pull-ups as documented in the FLEX 6000 datasheet referenced by Alldatasheet.

The 240-pin PQFP has 0.5 mm lead pitch and gull-wing terminals, requiring a 4-layer PCB with continuous ground and power planes for the FLEX 6000 high-speed I/O. Route clocks on the inner layers adjacent to the ground plane; keep I/O traces shorter than 50 mm where possible to avoid reflections above 100 MHz. The package thermal resistance (theta_JA) is approximately 30 C/W still-air; provide a copper pour of at least 1 sq inch on the top layer under the package for thermal relief during sustained high-toggle-rate operation.
