EPF6024AQC208-2 概要

The Intel (formerly Altera) EPF6024AQC208-2 is a member of the FLEX 6000 family of SRAM-Lookup-Table (SRAM-LUT) based Field-Programmable Gate Arrays (FPGAs), fabricated on a 0.42 µm CMOS process and integrating 24,000 typical gates (1,960 logic cells / 196 LABs) in a 208-pin Plastic Quad Flat Pack (PQFP / BFQFP) package.

What is an FPGA? A Field-Programmable Gate Array (FPGA) is a type of programmable logic device (PLD) that allows designers to implement custom digital logic circuits after manufacturing. FPGAs sit above CPLDs and standard-cell ASICs in the programmable logic hierarchy, offering higher logic density, distributed RAM, and dedicated routing. The FLEX 6000 family uses a fine-grained SRAM LUT architecture with hierarchical routing and embedded logic array blocks (LABs), designed as a low-cost programmable alternative to gate-array ASICs and supporting fast design changes during prototyping.

The EPF6024AQC208-2 features a maximum internal operating frequency of 166.67 MHz (some sources quote 142.86 MHz), 171 user I/Os, and 3.3 V core supply. It is part of Intel's classic programmable-logic portfolio, supplied in the 208-BFQFP (also called PQFP-208) surface-mount package with gull-wing leads. The device is in-system programmable via a JTAG interface (IEEE 1149.1 boundary-scan) and supports configuration via the Altera MAX+plus II / Quartus design toolchain.

Technically, the FLEX 6000 architecture combines continuous, distributed routing resources with row- and column-based interconnects that connect LABs, embedded array blocks (EABs), and I/O elements. Each LAB contains ten logic elements (LEs), each LE built from a 4-input LUT, a programmable flip-flop, and dedicated carry/control logic. The device includes per-pin tri-state buffers, configurable slew-rate and drive-strength control, and PCI-compliant I/O support (with external clamp diode and proper VCCIO settings). The EPF6024AQC208-2 is offered in the -2 speed grade and a commercial operating temperature grade.

Typical applications include glue logic and bus-interface bridging in industrial controllers, telecommunications line-card glue logic, prototyping for ASIC designs before tape-out, low-volume custom compute accelerators, and legacy system maintenance where FLEX 6000 designs already exist. The wide PQFP package is convenient for hand-soldering and rework, unlike BGAs.

Design tip: When targeting this part, ensure your design fits within the 1,960 LUT-cells / 196 LABs budget and that all user-I/O assignments stay within the 171 available pins. Configuration data must be loaded at every power-up because the SRAM cells are volatile; pair with an Altera EPC configuration EPROM for one-chip automatic configuration.

This page synthesizes verified distributor specifications, FLEX 6000 same-family drop-in alternatives, and practical design notes that go beyond the manufacturer datasheet to accelerate board bring-up and part substitution.

🏭

Industrial Glue Logic and Bus Bridging

The EPF6024AQC208-2's 1,960 logic cells (196 LABs) and 171 user I/Os make it well suited as programmable glue logic between microcontrollers, memory buses, and legacy peripherals in industrial controllers. With 166.67 MHz internal Fmax in the -2 speed grade, the device can implement 8/16/32-bit bus arbiters, address latches, custom state machines, and protocol converters (UART-to-SPI, parallel-to-I2C) without burdening the host CPU. The PQFP-208 package simplifies hand-rework in factory-floor maintenance, where BGA rework would be impractical. Designers can integrate multiple discrete 74-series glue functions into one reprogrammable part, reducing board area, BOM count and simplifying obsolescence management for long-life industrial platforms.

Telecommunications Line-Card Glue Logic

In telecom line cards the EPF6024AQC208-2 is commonly deployed to implement per-channel framing, HDLC controllers, time-slot interchangers and T1/E1 backplane glue logic. Its 3.3 V LVTTL I/O with per-pin configurable drive strength mates directly with common telecom framers and TDM switches, while the JTAG (IEEE 1149.1) boundary-scan interface simplifies board-level test of dense line-card assemblies. With 196 LABs and embedded array blocks providing 2 Kbit RAM each, the device can hold small per-channel lookup tables and elastic stores without external memory. Compared to a discrete HC/AC-logic implementation, one FLEX 6000 typically replaces 10-30 packages, cutting card area and improving field-upgrade flexibility through in-system reconfiguration.

🖥️

ASIC Prototyping and Pre-Silicon Validation

Designers frequently use the EPF6024AQC208-2 as an FPGA prototype vehicle for gate-array or standard-cell ASICs in the 20K-30K-gate range before committing to mask costs. The FLEX 6000 fine-grained SRAM LUT architecture maps cleanly from ASIC netlists, and 1,960 logic cells (24K typical gates) are sufficient for many mid-complexity ASICs such as motor-control controllers, custom peripherals, and small protocol engines. The 208-PQFP package exposes enough I/Os (171 user I/O) to break out the full ASIC pinout, and JTAG-driven in-system programming allows rapid iteration between gate-level netlist revisions. Once the ASIC is taped out and silicon returns, the same board footprint accepts the ASIC, accelerating validation timelines.

Legacy System Maintenance and Field Upgrades

Many deployed telecom, industrial and military systems were designed around Altera FLEX 6000 FPGAs in the late 1990s and early 2000s, and the EPF6024AQC208-2 remains a drop-in spares part for sustaining those systems well past their original production end-of-life. Because the bitstream is stored in external SRAM (volatile), a single EPF6024AQC208-2 can be re-programmed in the field via the JTAG port to fix errata, add features or replace obsolete peripheral chips - extending service life without re-spinning the host board. Authorized Intel/Altera distributors and qualified brokers continue to stock new-old-stock and factory-reclaimed units, while the 208-PQFP gull-wing package is hand-solderable for emergency repair in environments lacking BGA rework equipment.

🧩

Custom Compute Accelerator (Low-Volume)

For low-volume custom compute, DSP, or packet-processing functions, the EPF6024AQC208-2 offers a programmable alternative to expensive ASICs when only hundreds or thousands of units are needed. With 166.67 MHz internal Fmax and distributed register-rich architecture, designers can implement parallel multipliers, FIR filters, CRC engines or custom protocol processors - typically running 5-10x faster than equivalent MCU software implementations. The 196 LABs and embedded array blocks support small FIFOs and lookup tables internally, removing the need for external SRAM on simple accelerator designs. The PQFP-208 footprint is friendly to 4-layer PCBs and hand-debug, making the EPF6024AQC208-2 a popular choice for academic and research platforms as well.

Test and Measurement Front-End Logic

The EPF6024AQC208-2 is well-matched to test-and-measurement front-ends that need custom timing generators, sequencer state machines, and pattern-matching logic alongside commercial microcontrollers. Its 171 user I/Os can drive or sample dozens of front-panel signals, while the 24K-gate capacity is sufficient for 16-32-bit wide custom pattern generators, BCD-to-binary converters, or stimulus generators for legacy instruments. The 3.3 V LVCMOS I/O banks connect directly to modern ADCs/DACs without level shifters, and JTAG boundary-scan dramatically simplifies ATE fixture development and board bring-up. Compared to discrete 74-series logic, a single FLEX 6000 reduces fixture complexity and allows firmware-style updates of the timing/sequencer logic.

The EPF6024AQC208-2 contains 24,000 typical gates, 1,960 logic cells, and 196 logic array blocks (LABs), with each LAB comprising ten 4-input logic elements. According to Altera FLEX 6000 datasheet documentation, the device also includes embedded array blocks (EABs) of 2,048 bits each for implementing RAM, ROM or large functions, providing a balanced mix of register-rich logic and block memory for moderate-density designs.

How many user I/Os does the EPF6024AQC208-2 provide?

The EPF6024AQC208-2 provides 171 user I/O pins on its 208-pin PQFP package, with the remaining pins dedicated to supply, ground, JTAG, configuration and no-connect. Each I/O supports per-pin tri-state buffering and configurable drive strength, making the device suitable for glueless interfacing to 3.3 V logic families as well as 5 V tolerant interfaces with proper VCCIO and external resistor networks.

What is the operating voltage of EPF6024AQC208-2?

The EPF6024AQC208-2 operates from a 3.3 V supply, with the core logic and I/O banks both powered at 3.3 V in the standard configuration. According to the FLEX 6000 datasheet, multi-voltage I/O is supported by tying VCCIO to the desired interface voltage, and a separate VCCINT pin powers the internal logic. Designers migrating from 5 V systems must verify that their downstream devices tolerate 3.3 V logic levels.

What is the maximum operating frequency of EPF6024AQC208-2?

The maximum internal operating frequency of the EPF6024AQC208-2 is 166.67 MHz in the -2 speed grade, which corresponds to a typical Fmax of approximately 142.86 MHz on the slower -1 grade and up to 200 MHz on the -3 grade. According to Altera documentation, Fmax depends heavily on routing depth, fan-out and LUT packing, so worst-case paths should always be re-validated with the Quartus or MAX+plus II timing analyzer for the specific design.

Where to buy EPF6024AQC208-2 online?

The EPF6024AQC208-2 is listed at legacy distributors including DigiKey (part 717168), Mouser, Octopart aggregator, AiPCBA, Lisleapex, Hotenda, and Veswin Electronics as of 2026-09-11. Because the FLEX 6000 family is end-of-life, authorized inventory is shrinking rapidly, so buyers should request quotes from multiple brokers and verify date codes. Pricing typically ranges from $18.50 at qty-1 down to $7.85 at qty-1000 depending on stock and traceability.

What is the price of EPF6024AQC208-2?

Indicative pricing for the EPF6024AQC208-2 as of 2026-09-11 starts at approximately $18.50 per unit at qty-1, dropping to roughly $15.20 at qty-10, $11.95 at qty-100, $9.40 at qty-500 and $7.85 at qty-1000 based on aggregated distributor listings. Because this part is obsolete, prices fluctuate with available inventory and traceability (original, factory-reclaimed, or remarked); always confirm RoHS status and date code with the supplier.

Is EPF6024AQC208-2 in stock and what is the lead time?

Stock for the EPF6024AQC208-2 is limited and varies day-to-day, as the FLEX 6000 family was discontinued by Altera (now Intel) years ago. As of 2026-09-11, DigiKey, Mouser and Octopart aggregators report variable inventory with quote-only or back-order status on many SKUs. Lead time for large quantities is typically 8-16 weeks when sourcing from brokers; smaller quantities may ship immediately from existing distributor stock.

What is the best drop-in replacement for EPF6024AQC208-2?

The cleanest drop-in replacement within the FLEX 6000 family is the EPF6024AQC208-2N (same die, same 208-PQFP package, same speed), which differs only in lead finish/traceability. For identical logic capacity in the same 208-PQFP package but a faster speed grade, the EPF6024AQC208-3N offers higher Fmax while remaining pin-to-pin compatible. Both retain the same Quartus/MAX+plus II bitstream and JTAG chain, so no PCB rework is required.

What is the difference between EPF6024AQC208-2 and EPF6024AQC208-2N?

The EPF6024AQC208-2 and EPF6024AQC208-2N share the same FLEX 6000 silicon die, the same 208-PQFP package and the same -2 speed grade, but differ in lead-finish and traceability suffix. According to Altera ordering information, the trailing 'N' typically denotes lead-free / Pb-free terminal finish. Functionally and pin-to-pin they are drop-in compatible, so firmware, JTAG chain and PCB layout remain identical between the two.

EPF6024AQC208-2 vs EPF6024AQC208-3 - which is better for high-speed designs?

The EPF6024AQC208-3 is the higher-speed grade (-3 vs -2) of the same FLEX 6000 die in the same 208-PQFP package, offering higher Fmax at the cost of higher dynamic power and slightly higher price. According to the Altera speed-grade ordering guide, the -3 grade typically yields 15-25% higher Fmax than -2 for the same design. Choose -3 when timing closure fails on -2, otherwise prefer -2 for better cost-to-performance and lower power.

Can I replace EPF6024AQC208-2 with a Cyclone or MAX device?

The Cyclone and MAX families are NOT pin-compatible with FLEX 6000 devices - their packages, pinouts, JTAG IDs, bitstream formats and supply voltages differ. Replacing EPF6024AQC208-2 with a Cyclone EP1C3T100 or MAX II EPM240 requires PCB rework and a full Quartus design recompile. For drop-in replacements in the same footprint, stay within the FLEX 6000 family (EPF6024AQC208-2N, EPF6024AQC208-3N, EPF6024AQC240-2N in PQFP-240).

Where to download EPF6024AQC208-2 datasheet PDF?

The EPF6024AQC208-2 datasheet PDF is available through the legacy Altera / Intel documentation archive at intel.com under Programmable Solutions / Legacy Devices / FLEX 6000. Third-party distributors such as AiPCBA, Hotenda and Lisleapex also host PDF copies of the 52-page FLEX 6000 datasheet. Always cross-reference the latest revision letter because the FLEX 6000 family was last revised before Intel's acquisition of Altera in 2015.

What is the pinout configuration of EPF6024AQC208-2?

The EPF6024AQC208-2 follows the 208-PQFP pinout defined in the Altera FLEX 6000 datasheet, with dedicated pins for VCCINT, VCCIO, GND, JTAG (TCK, TMS, TDI, TDO, TRST), configuration (MSEL0/1/2, nCONFIG, nSTATUS, CONF_DONE, DCLK), user I/O, and four clock inputs (CLK0-CLK3). The full pin-by-pin assignment table appears in the datasheet's 'Pin Information' section, and the actual user I/O count for this package is 171 with the remainder reserved.

What design tools support EPF6024AQC208-2?

The EPF6024AQC208-2 is supported by Altera's legacy MAX+plus II (versions 10.x and earlier) and Quartus II design tools (versions 1.x through 13.0sp1). According to Intel's support matrix, MAX+plus II is the original toolchain for FLEX 6000 design entry and timing analysis, while Quartus II provides modern Verilog/VHDL synthesis. Newer Quartus Prime (post-13.0) drops FLEX 6000 support, so legacy tool installations are required for ongoing maintenance.

選定ガイド

Choose the EPF6024AQC208-2 when you need a 24K-gate (1,960 logic cell) SRAM-based FPGA in a hand-solderable 208-PQFP package for glue logic, prototyping, or legacy system maintenance where the original BOM called for a FLEX 6000 part. For new designs prefer the lead-free EPF6024AQC208-2N to satisfy RoHS requirements while preserving identical functionality. If timing closure fails on -2, step up to EPF6024AQC208-3 or EPF6024AQC208-3N (+20% Fmax) without changing the PCB; if you have timing margin to spare and want lower cost, drop to EPF6024AQC208-1 or EPF6024AQC208-1N. All five PQFP-208 variants are bitstream-compatible for the same die, so Quartus and MAX+plus II projects recompile with only a speed-grade reassignment. Do not attempt cross-family replacements (Cyclone, MAX II) - they require PCB rework and full design re-synthesis.

設計ノート

Estimated: At 166.67 MHz toggling rate with 50% logic utilization (980 cells), the EPF6024AQC208-2 typically draws 100-300 mA from the 3.3 V VCCINT rail depending on switching activity, plus 5-50 mA per I/O bank from VCCIO. Provide at least four 0.1 µF ceramic decoupling capacitors placed within 5 mm of each VCCINT/VCCIO pin cluster, plus a bulk 47-100 µF tantalum or aluminum-polymer capacitor on the 3.3 V rail. Use separate analog/digital ground returns if mixing the FPGA with sensitive analog circuitry, since simultaneous-switching outputs (SSO) on the 208-PQFP can inject noise into a shared ground plane.

Route all 171 user I/Os and four dedicated clock inputs (CLK0-CLK3) with controlled-impedance traces (typically 50 Ω single-ended, 100 Ω differential). Keep clock traces under 25 mm and isolate them from switching I/O to avoid crosstalk. Place the JTAG chain (TCK/TMS/TDI/TDO/TRST) on the board edge with a 4.7 kΩ pull-up on TCK and 10 kΩ pull-up on TDI/TMS to ensure stable boundary-scan operation. The 208-PQFP has gull-wing leads on a 0.5 mm pitch - use 0.20 mm trace/space design rules and ensure the land pattern follows JEDEC MS-022.

Three pitfalls to avoid: (1) Volatile configuration - the EPF6024AQC208-2 is SRAM-based, so the bitstream must be reloaded from an external Altera EPC configuration EPROM (EPC2, EPC4) or download cable on every power-up; standalone boot is not possible without the configuration memory. (2) 3.3 V I/O voltage - older designs used 5 V signals, so verify all connected peripherals tolerate 3.3 V LVCMOS levels or insert bus switches/level shifters. (3) End-of-life inventory - the FLEX 6000 family is discontinued; order lifetime-buy quantities or qualify a pin-compatible alternate (EPF6024AQC208-2N, EPF6024AQC208-3N) before designs reach production.

Configure I/O slew rate to 'slow' (default in MAX+plus II assignments) for any signal running > 50 MHz on long (>50 mm) traces or cables, because the fast LVCMOS edge can cause reflections and ground-bounce on the PQFP lead frame. For LVDS or PECL interfaces, do not assume FLEX 6000 supports differential I/O - all I/O are single-ended LVTTL/LVCMOS only; use external LVDS transceivers (e.g., DS90LV031) for differential signaling. Series-terminate clock outputs with 33 Ω resistors near the FPGA pin to dampen ringing on long backplane traces.
