EPF6024AQI208-4 Tóm tắt

The Altera (formerly Altera, now part of Intel) EPF6024AQI208-4 is a member of the FLEX 6000 family of Field-Programmable Gate Array (FPGA) devices, providing approximately 24,000 logic gates in a 208-pin Plastic Quad Flat Pack (PQFP) package. It is built on a CMOS SRAM process and offers 1960 logic elements (LEs) with 171 configurable I/O pins and 4 dedicated inputs, targeting glue-logic, bus-interface, and peripheral bridging applications that were mainstream in the late 1990s and early 2000s.

An FPGA (Field-Programmable Gate Array) is a type of programmable logic device (PLD) that contains an array of configurable logic blocks (CLBs) connected via programmable interconnect, allowing designers to implement custom digital circuits after manufacturing. FPGAs sit in the taxonomy as: PLD -> programmable logic -> FPGA -> SRAM-based FPGA -> FLEX 6000 family. Compared to CPLDs, FPGAs offer higher logic density and richer register-rich architectures but lose non-volatility, requiring an external configuration memory (typically an EPC2 or similar serial PROM).

Key features include 1960 logic elements organized as logic array blocks (LABs), embedded memory blocks, and a maximum clock frequency of 153 MHz. The device supports in-system programming via the FLEX 6000 configuration scheme, supports JTAG boundary-scan testing, and provides tri-state bus-friendly I/O with individually programmable slew-rate and drive-strength control per pin.

The FLEX 6000 architecture employs a four-input LUT-based logic element, FastTrack interconnect for predictable timing, and a continuous routing structure that simplifies place-and-route. Configuration bitstream loads from a serial EPROM or microprocessor interface, and the device supports passive parallel, passive serial, and JTAG configuration modes.

Typical applications include PCI bridge logic, legacy peripheral controllers, telecom line-card glue logic, industrial control boards, and replacement of discrete 74-series TTL/MSI gate arrays in long-lifecycle systems. The wide 171 I/O count suits bus-intensive designs.

When designing with this FPGA, ensure configuration storage is provisioned and verify the speed grade (-4) matches timing closure requirements for the target logic. The -4 speed grade is one of the slower grades; newer logic designs should be verified against timing analysis.

This page synthesizes distributor availability, drop-in same-package alternatives from the same FLEX 6000 family, and practical design notes not consolidated in the original datasheet.

Ứng dụng tiêu biểu

EPF6024AQI208-4 phù hợp cho 6 Áp dụngs: PCI Bridge Glue Logic, Legacy Peripheral Controllers, Telecom Line-Card Glue Logic, Industrial Control Boards, Bus Interface Bridging, Replacement of Discrete 74-Series TTL/MSI.

🌐

PCI Bridge Glue Logic

The EPF6024AQI208-4's 1960 LEs and 171 I/O pins make it well suited to PCI 2.2/3.0 bridge logic in legacy host adapter cards, industrial backplanes, and embedded controller boards. Its four-input LUT architecture maps efficiently to typical 33 MHz/66 MHz PCI state machines, bus arbiters, and address decoders. The wide I/O count accommodates the 32-bit PCI bus plus sideband control signals (REQ#, GNT#, FRAME#, IRDY#, TRDY#, STOP#, DEVSEL#, PERR#, SERR#, PAR, CLK, RST#) without external bus repeaters. Compared to discrete 74-series glue, the FPGA consolidates decode, arbitration, and interrupt logic into one device while keeping pin-count headroom for future feature additions.

Legacy Peripheral Controllers

Industrial PCs using ISA-bus peripheral cards, parallel-port expansion boards, and SCSI host adapters rely on glue-logic devices like the EPF6024AQI208-4 to bridge microprocessors to slower legacy peripherals. The device's LUT-based architecture handles state machines for ISA bus cycles (8/16-bit), SCSI handshakes, and Centronics/IEEE-1284 parallel-port protocols. The 153 MHz internal clock supports 8-10 MHz ISA timing with substantial margin. Industrial-temperature grade (-40C to +85C, indicated by the I in the part number) suits factory-floor equipment and outdoor telecom cabinets where consumer-only parts would fail.

Replacement of Discrete 74-Series TTL/MSI

Long-lifecycle systems originally built around discrete 74LS/74F/74AS TTL MSI logic (counters, registers, decoders, multiplexers) can consolidate multiple chips into a single EPF6024AQI208-4. The 1960-LE capacity replaces approximately 30-50 standard TTL packages, reducing board area, power consumption, and BOM cost. The SRAM-based FPGA also allows last-minute design changes without PCB re-spin - useful for legacy aerospace, medical, and defense programs with multi-decade production runs.

What family does EPF6024AQI208-4 belong to?

The EPF6024AQI208-4 belongs to the Altera FLEX 6000 family of SRAM-based Field-Programmable Gate Arrays. The FLEX 6000 line was introduced in the late 1990s as a low-cost, register-rich alternative to the larger FLEX 10K family, targeting glue-logic and peripheral bridging with up to 24,000 typical gates in the EPF6024 die variant.

How many logic elements does the EPF6024AQI208-4 contain?

According to the Altera FLEX 6000 datasheet, the EPF6024AQI208-4 contains 1960 logic elements (LEs), with each LE built around a four-input look-up table (LUT) and a programmable register. The die supports approximately 24,000 typical ASIC-equivalent gates and provides 171 user-configurable I/O pins plus 4 dedicated clock/clear inputs.

What package does the EPF6024AQI208-4 use?

The EPF6024AQI208-4 ships in a 208-pin Plastic Quad Flat Pack (PQFP) with 0.500 mm terminal pitch. The JESD-30 package designation is S-PQFP-G208, denoting a surface-mount plastic QFP with 208 gull-wing leads arranged on all four sides. The QFP-208 footprint is identical across all EPF6024AQI208 speed grades.

Where can I buy EPF6024AQI208-4 today?

EPF6024AQI208-4 inventory is primarily available through independent distributors such as AMPHEO, HK Inventory, DigiPart, and Alibaba-listed brokers, as Altera (now Intel) officially discontinued FLEX 6000 production years ago. Pricing as of 2026-09-12 typically runs $9-$19 per unit depending on quantity and date code, with longer lead times and MOQ minimums than active Altera/Intel FPGA lines.

What is the lead time for EPF6024AQI208-4?

Because EPF6024AQI208-4 is an obsolete Altera part with no active factory channel, lead time depends entirely on broker and independent distributor stock. Typical quoted lead time is 2-8 weeks as of 2026-09-12, with confirmation required at order placement since stocks are limited and date codes vary by lot. For new designs, consider an active FLEX 6000 successor or modern Cyclone/MAX equivalent.

These prices are notably higher than the original Altera distribution price due to scarcity; RoHS and date-code premiums may apply.

Is EPF6024AQI208-4 in stock?

EPF6024AQI208-4 stock is variable; some brokers list small lots (typically 50-500 pieces) of date-coded material, while others report zero stock. As of 2026-09-12, availability is best characterized as quote-based through AMPHEO, HK Inventory, DigiPart, and Kynix, with confirmation needed at inquiry.

What is the difference between EPF6024AQI208-4 and EPF6024AQI208-3?

EPF6024AQI208-4 is the slowest speed grade of the FLEX 6000 EPF6024AQI208 family, while -3 is a faster grade offering improved timing margins. Both share the identical QFP-208 PQFP package, pinout, and 1960-LE die. Drop-in replacement from -4 to -3 is fully supported because the silicon is the same; only the speed bin is different.

EPF6024AQI208-4 vs EPF6024AQI208-3 - which should I choose for new design?

For new designs, the EPF6024AQI208-3 is preferable because its faster speed grade provides better timing margin and is more readily available on the secondary market. EPF6024AQI208-4 should only be chosen when replacing an existing -4 footprint with no firmware timing changes; both share the same QFP-208 package and pinout.

When should I choose EPF6024AQI208-4 over EPF6016QI208-3?

Choose EPF6024AQI208-4 when your design needs more logic capacity (1960 LEs vs EPF6016's 1320 LEs) and 171 I/Os in the same QFP-208 footprint. Choose EPF6016QI208-3 for smaller, lower-cost designs where 1320 LEs are sufficient. Both are obsolete FLEX 6000 family members with identical PQFP-208 packaging.

What is the best drop-in replacement for EPF6024AQI208-4?

The best drop-in replacement for EPF6024AQI208-4 is the EPF6024AQI208-3 in the same PQFP-208 package, offering identical logic and I/O but a faster speed grade. Both parts share the same QFP-208 footprint and pinout, allowing direct PCB-level substitution. The -3 grade is generally more available on the secondary market.

Where to download EPF6024AQI208-4 datasheet PDF?

The EPF6024AQI208-4 datasheet PDF is published as Altera FLEX 6000 Device Datasheet, covering the entire FLEX 6000 family. It is hosted on the Altera/Intel literature archive. Search query "FLEX 6000 datasheet Altera dsf6000.pdf" retrieves the document from the official archive. Third-party sources also redistribute the PDF.

Where to find EPF6024AQI208-4 pinout?

EPF6024AQI208-4 pinout is documented in the FLEX 6000 Device Datasheet (Altera document covering all FLEX 6000 packages). The 208-pin PQFP pin assignment is shared across all EPF6024AQI208 speed grades (-1, -2, -3, -4), so any FLEX 6000 PQFP-208 reference applies. Ball/pin map is on the package diagram page of the datasheet.

Can EPF6024AQC208-3 replace EPF6024AQI208-4?

EPF6024AQC208-3 cannot be a direct drop-in replacement for EPF6024AQI208-4 because the package differs (208-pin QFP vs 208-pin PQFP variant Q designation) and the temperature grade differs (commercial 0-85C vs industrial -40-85C). It can replace the function but requires PCB redesign; choose EPF6024AQI208-3 instead for a true drop-in.

Hướng dẫn chọn lựa

Choose EPF6024AQI208-4 only when maintaining an existing FLEX 6000 design with -4 speed grade timing. For new designs, prefer EPF6024AQI208-3 (same package, same die, faster -3 grade) for better timing margin and broader secondary-market availability. Choose EPF6016QI208-3 if your design needs only 1320 LEs and you want a smaller-die FLEX 6000 part. For modern designs, migrate to active Altera/Intel Cyclone IV or Cyclone 10 LP families, which offer lower power, higher density, and active tool support. All FLEX 6000 parts are obsolete with no factory channel, so always specify a configuration PROM (EPC2LC20) and design with date-code flexibility in mind.

Ghi chú thiết kế

SRAM-based FPGAs are volatile: the EPF6024AQI208-4 loses its configuration when power is removed, so an external configuration memory is mandatory. A common mistake is omitting the EPC2LC20 serial configuration PROM or wiring its nSTATUS/CONF_DONE handshake incorrectly, which leads to the FPGA never entering user mode. Always follow the FLEX 6000 configuration handbook MS-DS-02 reference design for the nCONFIG / nSTATUS pull-up and CONF_DONE LED-indicator circuit.

PQFP-208 with 0.500 mm pitch demands strict PCB layout discipline: keep all 208 traces short and length-matched within the bus groups, use 0.200 mm wide traces with 0.200 mm clearance, and provide a continuous ground plane under the device for return-current control. Decoupling: place 0.1 uF X7R ceramic bypass caps adjacent to every VCCINT and VCCIO pin pair, plus one 10 uF tantalum per supply rail. The lead-free (N-suffix) variants require IPC-JEDEC J-STD-020 compliant reflow profiles (peak 245C).

Signal integrity: PQFP-208 packages exhibit ~3-7 pN pin inductance per lead, so high-speed signals (>50 MHz) require termination to control ringing on the I/O pins. Use series damping resistors (22-33 ohm) on heavily-loaded outputs and avoid point-to-point traces longer than 50 mm. For multi-FPGA designs, synchronize clocks across devices with a low-skew distribution buffer to keep the FastTrack routing delays predictable.
