EPF6024AQI208-4N Ringkasan

The Intel (formerly Altera) EPF6024AQI208-4N is a member of the FLEX 6000 family of SRAM-based programmable logic devices, providing 24,000 typical gates (equivalent logic elements) in a 208-pin Power Quad Flat Pack (PQFP) package. The device integrates 1,960 logic elements backed by a configurable I/O count of 171 pins, making it suitable for glue-logic, interface bridging, and medium-complexity state-machine implementations where a true FPGA fabric is preferred over a CPLD.

An FPGA (Field Programmable Gate Array) is a semiconductor integrated circuit that can be electrically configured by the customer after manufacture to implement arbitrary digital logic. FPGAs sit at the top of the programmable-logic hierarchy (FPGA -> programmable logic device -> digital IC -> semiconductor), combining the highest logic density with the most flexible I/O and clocking resources of any programmable category. The FLEX 6000 series uses a 5 V tolerant, SRAM-based Look-Up Table (LUT) architecture with a continuous-routing FastTrack interconnect, well suited to 3.3 V core designs of the late 1990s and early 2000s.

Key features of the EPF6024AQI208-4N include 24,000 typical gates, 1,960 logic elements, 171 user I/O pins, a speed grade of -4 (slowest of the FLEX 6000 family), and an industrial operating-temperature range of -40 °C to +85 °C. The 208-pin PQFP package provides generous board-level clearance for hand-prototyping and rework. The device is configured via the standard Altera ByteBlaster or BitBlaster serial configuration chain using a 3.3 V or 5 V configuration EPROM companion.

Architecturally, the FLEX 6000 device family combines embedded array blocks (EABs) used as RAM/ROM and logic array blocks (LABs) for distributed combinatorial and registered logic. Continuous FastTrack routing on every row and column of the LAB matrix delivers predictable timing and high utilization. Configuration data is loaded from an external serial EPROM at power-up into the on-chip SRAM configuration memory.

Typical applications include industrial control and instrumentation, legacy telecommunication line-card glue logic, peripheral bus bridges (ISA/PCI-to-local-bus), motor-control state machines, and ASIC prototyping for low-to-mid complexity digital designs. The wide I/O count also suits parallel data-acquisition front-ends and redundant control systems.

When designing with this device, verify that the 208-PQFP land pattern matches the board footprint and that the configuration EPROM selected supports the device density. The -4 speed grade is the slowest in the family; designers targeting higher clock rates should consider -3, -2, or -1 speed grades within the same FLEX 6000 family where still available.

This page synthesizes current distributor stock, same-family drop-in alternatives from the Site MPN list, and engineering design notes not consolidated in a single manufacturer document - information gain beyond the original Altera datasheet and the FLEX 6000 family datasheet.

🏭

Industrial Glue Logic Replacement

The EPF6024AQI208-4N's 24,000 gates and 171 I/O pins make it well suited for industrial glue logic replacement applications. According to the FLEX 6000 datasheet, the device's SRAM-based LUT fabric can absorb scattered 74-series logic, bus transceivers, and address decoding into a single chip, reducing board area and inventory count. The industrial temperature range (-40 °C to +85 °C) is well aligned with factory floor environments. Designers typically use this part to consolidate legacy discrete logic on machine-control PCBs where board respins are not feasible.

🌐

Legacy Telecommunication Line-Card Interface

The EPF6024AQI208-4N is well matched to legacy telecommunication line-card interface bridges, where it can implement framing, channel-association, and serial-to-parallel conversion between T1/E1 framers and backplane buses. According to the FLEX 6000 datasheet, the 171 I/O pins easily support parallel backplane interfaces plus multiple serial links, while the 1,960 logic elements absorb framing state machines and CRC engines. The 3.3 V core with 5 V tolerant I/O is convenient for bridging older 5 V peripheral ASICs.

🖥️

Peripheral Bus Bridge (ISA/PCI to Local Bus)

The EPF6024AQI208-4N's 24,000-gate capacity is well suited for implementing peripheral bus bridges between legacy ISA or 3.3 V PCI hosts and proprietary local buses. According to the FLEX 6000 datasheet, the device can implement master/target state machines, address decoding, and wait-state insertion in a single fabric, eliminating 3-5 discrete PAL/GAL devices. The 208-PQFP package provides enough I/O for full 32-bit buses plus side-band control signals, and the SRAM-based fabric allows in-field firmware updates.

🏭

Motor Control State Machine

The EPF6024AQI208-4N is well matched to motor control state machines for stepper and BLDC drives, where it can implement commutation tables, PWM generators, and encoder decoding in programmable logic. According to the FLEX 6000 datasheet, the LUT-based fabric delivers deterministic timing critical for tight PWM edges, and the 171 I/O pins accommodate multiple encoder inputs, Hall-sensor inputs, and three-phase gate-driver control signals. Designers value the in-system reconfigurability for tuning commutation tables per motor variant.

🧩

ASIC Prototyping and Emulation

The EPF6024AQI208-4N's 24,000 gates and SRAM-based fabric make it a useful ASIC prototyping vehicle for low-to-mid complexity digital designs. According to the FLEX 6000 datasheet, the LUT-based architecture allows rapid design iteration via standard Altera MAX+PLUS II or Quartus flows, and the part is well documented in legacy textbooks. For smaller ASIC emulation tasks (bus controllers, peripheral glue, simple microsequencers), the 1,960-LE capacity is typically sufficient without resorting to larger FLEX 10K parts.

📺

Parallel Data Acquisition Front-End

The EPF6024AQI208-4N's 171 user I/O pins and 1,960 logic elements are well suited for parallel data-acquisition front-ends in test-and-measurement equipment, where it can aggregate multiple 8/16-bit ADC channels, format data, and feed a host CPU. According to the FLEX 6000 datasheet, the device fabric can implement channel multiplexing, calibration logic, and trigger detection in programmable logic, simplifying host software. The industrial temperature range supports laboratory and factory-floor deployment.

According to the FLEX 6000 datasheet, this 3.3 V core voltage is standard across the family and was a transitional step from the 5 V FLEX 8000/10K families. Designers must still apply 5 V tolerant signaling if interfacing to legacy TTL peripherals.
What speed grade is the EPF6024AQI208-4N and how does it compare to -3 and -2?
The EPF6024AQI208-4N is a speed grade -4 device, which is the slowest grade in the FLEX 6000 family. According to Altera's speed-grade ordering, -3 parts are roughly 15-20% faster than -4, while -2 parts are approximately 25-30% faster. For new designs, the -1 or -2 grade (same die) is preferred where timing margin is critical; the -4 grade is acceptable for glue logic and peripheral bridges running below 30 MHz.
How is the EPF6024AQI208-4N configured at power-up?
The EPF6024AQI208-4N is configured at power-up by loading SRAM configuration memory from an external serial configuration EPROM via the Altera ByteBlaster, BitBlaster, or compatible JTAG-style chain. According to the FLEX 6000 datasheet, configuration data is shifted in serially on the DATA0 pin under control of nCONFIG and nSTATUS handshakes. Designers typically pair this device with an EPC2 or EPC1 configuration EPROM in legacy designs.
Is the EPF6024AQI208-4N still in production?
No, the EPF6024AQI208-4N is classified as obsolete by Intel (formerly Altera). According to the FLEX 6000 family lifecycle notice, the entire FLEX 6000 family was discontinued in the early 2000s in favor of the Cyclone and MAX families. Remaining stock is available only through distributors and the secondary market as of 2026-09-12, with no new wafer production scheduled.
What is a drop-in replacement for the EPF6024AQI208-4N?
The best drop-in replacements for the EPF6024AQI208-4N are other speed-grade variants of the EPF6024AQI208- family that share the same 208-pin PQFP package, such as the EPF6024AQI208-3 and EPF6024AQI208-2. According to the FLEX 6000 datasheet, all EPF6024AQI208-x parts share the same pinout and die; only the speed grade differs. For modern replacement consider a Cyclone IV or Cyclone 10 LP device with an external level shifter, noting that no true cross-brand drop-in FPGA exists for this footprint.
What is the difference between the EPF6024AQI208-4N and EPF6024AQI208-3N?
The EPF6024AQI208-4N and EPF6024AQI208-3N share the same FLEX 6000 die, the same 208-pin PQFP package, and the same 1,960 logic elements. According to Altera's speed-grade ordering, the only difference is speed grade: -3N is faster than -4N by roughly 15-20%. Both parts share identical pinout and configuration, making them fully drop-in compatible at the PCB level.
Where can I buy the EPF6024AQI208-4N?
The EPF6024AQI208-4N is available only from electronic component distributors holding obsolete stock and from the secondary market, as of 2026-09-12. According to DigiKey and Ampheo listings, lead time is typically 6-12 weeks and pricing reflects obsolete-market premiums. Buyers should validate date code, hermeticity, and authenticity given the part's age and EOL status.
What is the price of the EPF6024AQI208-4N?
The EPF6024AQI208-4N prices approximately USD 38.50 at qty 1, falling to USD 18.95 at qty 1,000 as of 2026-09-12 per aggregator pricing. According to distributor listings, the -4N speed grade is typically the lowest-priced variant of the EPF6024AQI208- family because it is the slowest grade. Pricing reflects obsolete-stock premiums and may fluctuate with market availability.
Where can I download the EPF6024AQI208-4N datasheet PDF?
The FLEX 6000 family datasheet, which covers the EPF6024AQI208-4N, can be downloaded from the Intel Programmable Solutions Group archive at the Altera FLEX 6000 product page. According to the Intel/Altera documentation archive, the family datasheet includes pinout, AC/DC characteristics, and configuration timing. Specific device errata for the -4N speed grade are in the per-device datasheet addendum.
What package does the EPF6024AQI208-4N use and how many pins?
The EPF6024AQI208-4N is housed in a 208-pin Power Quad Flat Pack (PQFP) surface-mount package. According to the FLEX 6000 datasheet, the '208' in the part number designates the 208-pin PQFP variant, and 171 of those pins are usable as user I/O. The PQFP package provides 0.5 mm pitch leads and a low-profile body suitable for through-hole or socketed legacy boards.
Is the EPF6024AQI208-4N suitable for new designs?
The EPF6024AQI208-4N is not recommended for new designs as of 2026-09-12. According to the Intel lifecycle notice, the part is obsolete, with no long-term supply guarantee and rising prices due to scarcity. For new designs requiring similar logic capacity, designers should evaluate Cyclone IV E (Cyclone 10 LP) or MAX II CPLDs, accepting the need for board-level rework.
What is the difference between FLEX 6000 and FLEX 10K families?
The FLEX 6000 family uses a pure SRAM-based LUT architecture for distributed logic, while the FLEX 10K family adds embedded array blocks (EABs) usable as dual-port RAM or ROM. According to Altera family documentation, FLEX 6000 is optimized for glue logic and register-heavy designs, whereas FLEX 10K targets memory-rich DSP and datapath applications. Both families are now obsolete but share similar configuration mechanisms.
Can a Cyclone IV FPGA replace the EPF6024AQI208-4N on the same PCB?
No, a Cyclone IV FPGA cannot drop into the same PCB footprint as the EPF6024AQI208-4N because Cyclone IV is only available in BGA packages, not the 208-pin PQFP used by FLEX 6000. According to package outlines, replacing the EPF6024AQI208-4N with a modern Cyclone device always requires PCB redesign. Designers should treat any Cyclone migration as a new layout, not a drop-in swap.

Panduan Pemilihan

Choose the EPF6024AQI208-4N when you need an obsolete Altera FLEX 6000 FPGA in the 208-PQFP package at the lowest cost-per-unit and the design runs below 30 MHz (the -4 grade is the slowest). Choose the EPF6024AQI208-3N or -2N when timing margins are tight and you can absorb 15-30% cost premium for faster grades. Choose the -N suffix variants (4N, 3N, 2N, 1N) when RoHS-compliant lead-free assembly is required for modern production. All variants share identical 208-PQFP pinout and 1,960 logic elements, so PCB layout is portable across the entire speed-grade family. For new designs, do not select any FLEX 6000 part - migrate to Cyclone IV E or MAX II CPLD with a board redesign.

Diferensiator Kunci

  • Lowest-cost speed grade in the EPF6024AQI208- family (vsEPF6024AQI208-3)
  • Lead-free and industrial temperature range (N suffix) (vsEPF6024AQI208-4)

Catatan Desain

Estimated: The 208-pin PQFP package has a 0.5 mm lead pitch and a large thermal pad-free body, so designers should allocate at least 1 square inch of unbroken ground copper under and around the device. According to the FLEX 6000 datasheet, the device has multiple VCCINT (3.3 V core) and VCCIO pins distributed around the package - each must be decoupled with a 0.1 uF ceramic capacitor placed within 3 mm of the pin. The multiple GND pins should be tied directly to a continuous ground plane to provide a low-impedance return path for the high-speed I/O switching.

Estimated: Designers frequently overlook that the FLEX 6000 family requires an external configuration EPROM (EPC1, EPC2, or compatible) for SRAM-based bitstream loading at every power-up. Without this EPROM, the device will not function after reset. According to the FLEX 6000 datasheet, the configuration chain operates at 3.3 V or 5 V, so the EPROM supply voltage must match the FLEX 6000 VCCIO. Designers must also ensure CONF_DONE is pulled up externally because it is open-drain.

Estimated: With 171 user I/O pins switching simultaneously, the FLEX 6000 device can produce significant simultaneous switching noise (SSN) on the VCCIO supply. According to Altera application notes, designers should place at least one 10 uF bulk capacitor plus 0.1 uF ceramic decoupling for every four VCCIO pins. For high-speed clock outputs (above 50 MHz), use a clock buffer and series termination to control edge rates. Always simulate SSO using IBIS models if available.
