EPF6024AQC240-3N Overview
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.

Typical Applications
EPF6024AQC240-3N is suitable for 6 applications: 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.
Recommended
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.
Recommended
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.
Recommended
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.
Recommended
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.
Recommended
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.

Key Differentiators
- Highest speed grade in the EPF6024AQC240 family at -3 (vs EPF6024AQC240-2N)
- Pin-compatible lead-free RoHS option in same package (vs EPF6024AQC240-3 (leaded))
- SRAM-based reconfigurability versus hard-wired gate array (vs ASIC gate array of equivalent gate count)
Design Notes
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.
Compliance Information
The 'N' suffix in EPF6024AQC240-3N indicates a lead-free terminal finish consistent with RoHS. AEC-Q100 qualification is not applicable to this FLEX 6000 family part; the device is not automotive-grade. REACH and conflict-minerals status not explicitly stated on the Altera datasheet referenced by Alldatasheet.
