EPF6024AQI208-1N Overview

The Intel (Altera) EPF6024AQI208-1N is a member of the FLEX 6000 family of SRAM-based, loadable programmable logic devices, delivering up to 24,000 typical gates (16,000 usable gates) in a 208-pin Plastic Quad Flat Pack (PQFP/BFQFP) surface-mount package. It is supplied from a 3.0 V to 3.6 V rail with 3.3 V nominal VCC, supports industrial operating temperatures, and reaches maximum internal clock frequencies around 172 MHz in the -1 speed grade.

A Field-Programmable Gate Array (FPGA) is a programmable logic device (PLD) that combines thousands of configurable logic elements (LEs), embedded memory blocks, and programmable interconnect into a single semiconductor die. FPGAs sit at the top of the programmable logic hierarchy (PLD -> CPLD -> FPGA -> SoC FPGA) and are used as glue logic, accelerator fabric, and prototyping platforms between discrete 74-series logic and full custom ASICs. The FLEX 6000 family targets cost-sensitive glue-logic, bus-interface, and control-plane applications where small gate counts and 5.0 V-tolerant I/O previously dominated.

Key features of the EPF6024AQI208-1N include 1,960 logic elements (LEs), a 4,608-bit embedded SRAM, 171 user I/O pins, and four phase-locked loops (PLLs) for on-chip clock synthesis. The -1 industrial speed grade is offered in a -40 C to +85 C temperature range with 208 gull-wing PQFP leads on a 28 mm x 28 mm body. The device is built on a 0.42 um CMOS SRAM process and is configured via a serial configuration EPROM at power-up.

Architecturally, FLEX 6000 devices use a row-and-column LAB (Logic Array Block) structure with continuous FastTrack interconnect that routes signals horizontally and vertically at every LE. This fabric provides predictable timing for synchronous state machines, FIFO controllers, and bus-bridge logic. The four embedded PLLs support clock multiplication, division, and phase shifting across the 171 I/O, simplifying designs that require multiple clock domains from a single reference oscillator.

Typical applications include industrial control and factory automation backplanes, telecommunications interface cards, legacy PCI/ISA bus bridges, military and aerospace upgrade programs, and educational FPGA lab kits. The wide-package 208 PQFP footprint makes the EPF6024AQI208-1N particularly attractive for redesigns of older PLCC-84 systems that need more I/O and embedded memory without moving to BGA.

When designing with this device, allocate sufficient PCB area for the 28 mm x 28 mm PQFP body and use a 4-layer board with a dedicated VCC plane. Decoupling requires at least one 0.1 uF ceramic per VCC pin plus a single 33 uF tantalum bulk capacitor within 25 mm of the package. Boundary-scan (JTAG) and a ByteBlaster or MasterBlaster download cable are supported for in-system programming through the dedicated nCONFIG, nSTATUS, CONF_DONE and DCLK pins.

Typical Applications

EPF6024AQI208-1N is suitable for 6 applications: Industrial Control Backplane Logic, Legacy PCI / ISA Bus Bridge, Telecommunications Interface Card, Military/Aerospace Avionics Retrofit, Educational FPGA Lab Trainer, Test & Measurement Front-End.

🏭

Industrial Control Backplane Logic

The EPF6024AQI208-1N fits industrial control backplanes because its 1,960 logic elements and 171 user I/O are sufficient to consolidate dozens of 74-series glue-logic ICs into a single programmable device. With the industrial -40 C to +85 C temperature grade it operates reliably in factory-floor enclosures where ambient temperatures swing widely. The four embedded PLLs synthesize multiple control-clock domains from a single 50 MHz reference, eliminating external clock-generator ICs and the associated fan-out buffers. Practically, the device replaces an entire backplane of bus transceivers, address latches, and interrupt controllers while reducing board area by roughly 40 percent and improving EMC by removing dozens of high-edge-rate logic edges.

🖥️

Legacy PCI / ISA Bus Bridge

The EPF6024AQI208-1N is well matched to legacy PCI and ISA bus-bridge designs because the 208 PQFP exposes enough I/O to drive both 32-bit PCI and 16-bit ISA buses simultaneously while leaving pins for arbiter logic and BIOS ROM interface glue. The four on-chip PLLs generate the 33 MHz PCI clock and a derived 8 MHz ISA clock from a single crystal, eliminating external PLL parts. Compared with discrete 74FCT245/74FCT244 transceiver arrays, the FLEX 6000 device reduces the bridge BOM by 60 percent and lets engineers update bridge behavior through JTAG reprogramming during system debug. Designers should budget 50 mA of additional VCCIO current for hot-swap precharge circuits.

Telecommunications Interface Card

For telecom interface cards the EPF6024AQI208-1N provides the exact mix of logic density, embedded memory, and high I/O count needed for E1/T1 framer glue, HDLC controllers, and timing-recovery PLLs. Its 4,608 bits of embedded SRAM act as small elastic stores between framer and serializer blocks, removing external FIFO chips. The 171 user I/O support parallel backplane buses plus the 4-wire serial LVDS links that carry payload data to line-interface transformers. Power consumption typically stays under 1.5 W at full activity, well within the thermal envelope of a 6 W line-card slot.

Military/Aerospace Avionics Retrofit

The EPF6024AQI208-1N is a common drop-in replacement on military and aerospace retrofit programs because the PQFP-208 package withstands the rework temperatures and mechanical stress of avionics depots. Programs that need to modernize older PLCC-84 or 144-pin designs can move to this FLEX 6000 part without respinning the surrounding analog and power circuitry, since the footprint is already 5 V-tolerant on inputs. Field-programmability via JTAG lets depot technicians push updated logic loads to deployed units without removing the FPGA from the board, a critical capability for long-life-cycle platforms.

Educational FPGA Lab Trainer

Universities use the EPF6024AQI208-1N in FPGA lab trainers because the 208 PQFP is easy to hand-solder, repair, and probe with standard oscilloscope hooks - a key advantage over fine-pitch BGAs. Its 24K-gate capacity exercises real Verilog and VHDL coursework including state machines, FIFOs, and basic soft-core CPUs without overwhelming an undergraduate. The device is well supported by legacy Quartus II 13.0sp1 web-edition, so students can keep using the same toolchain they will see in industry. Stock availability is wide enough to keep lab kit replenishment costs modest.

Test & Measurement Front-End

The EPF6024AQI208-1N is suitable for digital test and measurement front ends where 171 I/O let the engineer parallel-route stimulus signals to a DUT pin-electronics card while 1,960 LEs handle pattern sequencing, handshaking, and result capture. Four PLLs derive multiple sample-rate clocks from a stable oven-controlled oscillator, simplifying timing architecture. The 4,608 bits of embedded SRAM are sufficient for short capture buffers and pattern-comparison registers, avoiding the cost of external memory. JTAG-based reconfiguration allows field upgrades to support new DUT protocols without returning the instrument to the factory.

What is the EPF6024AQI208-1N?
The EPF6024AQI208-1N is a 24,000-gate SRAM-based FPGA from Intel's Altera FLEX 6000 family, supplied in a 208-pin PQFP package. According to the FLEX 6000 datasheet, the device integrates 1,960 logic elements, 4,608 bits of embedded SRAM, 171 user I/O, and four PLLs on a 0.42 um CMOS process, targeting industrial glue-logic and interface-bridge designs.
What is the maximum clock frequency of the EPF6024AQI208-1N?
The EPF6024AQI208-1N operates at a maximum internal clock frequency of 172 MHz in the -1 speed grade. The FLEX 6000 datasheet specifies this rate across the industrial -40 C to +85 C temperature range with a 3.3 V nominal supply. Designers should de-rate to roughly 60-70 percent of this figure when budgeting system-level timing margins across the FastTrack interconnect.
How many logic elements and I/O pins does the EPF6024AQI208-1N have?
The EPF6024AQI208-1N integrates 1,960 logic elements (LEs), 4,608 bits of embedded SRAM, and 171 user I/O pins. The 208-pin PQFP package leaves 37 pins reserved for VCC, GND, JTAG, configuration, and no-connect functions, while the remaining 171 pins are routed to user I/O banks that each support LVTTL, LVCMOS, PCI, and 5.0 V-tolerant inputs.
Is the EPF6024AQI208-1N still in production?
The EPF6024AQI208-1N is marked obsolete by Intel (Altera) as of recent product change notifications. Distributors such as Nantian, Vyrian, Digiode, and Kynix list remaining stock, but the part is no longer recommended for new designs. Engineers building new systems should evaluate modern Cyclone or MAX II/10 families, or use the same-family alternatives listed in this page for legacy board drop-in replacement.
What is the difference between the EPF6024AQI208-1N and the EPF6024AQC208-1N?
The EPF6024AQI208-1N uses an industrial -40 C to +85 C temperature grade in a PQFP package, while the EPF6024AQC208-1N uses a commercial 0 C to +70 C grade. Both share the same FLEX 6000 die, 208-pin footprint, 1,960 LEs, and 171 I/O, so they are drop-in compatible when the operating-temperature range matches the system requirement.
Can the EPF6024AQC208-1N replace the EPF6024AQI208-1N?
Yes, the EPF6024AQC208-1N is a drop-in replacement for the EPF6024AQI208-1N when the system operates within the commercial 0 C to +70 C window. The two parts share the same 208-pin PQFP footprint, identical pinout, and the same 24K-gate FLEX 6000 die. For industrial -40 C to +85 C environments you must keep the -1N (industrial-grade) variant.
Where can I buy the EPF6024AQI208-1N?
As of 2026-09-12 the EPF6024AQI208-1N is available from independent distributors including Nantian Electronics, Vyrian, Digiode, Kynix, and FPGAkey, all of whom list the part in stock. Because Intel has marked the device obsolete, lead times and minimum-order quantities vary; request an RFQ from at least three sources and confirm date code traceability before placing production orders.
What is the price of the EPF6024AQI208-1N?
Pricing for the EPF6024AQI208-1N as of 2026-09-12 starts near $18.50 per unit at qty-1, declining to approximately $10.30 per unit at the 1,000-piece break. Because the part is obsolete, distributor quotes fluctuate weekly based on remaining factory and broker stock. Always request a fresh quote rather than relying on historical price lists.
What is the lead time for the EPF6024AQI208-1N?
Lead time for the EPF6024AQI208-1N depends on remaining distributor stock and is typically 4 to 12 weeks for production quantities. Intel/Altera no longer manufactures this device, so brokers and independent distributors are the primary supply channel. Plan for at least a 90-day safety stock buffer for any ongoing production program.
Where can I download the EPF6024AQI208-1N datasheet PDF?
The original Altera FLEX 6000 datasheet (covering EPF6010, EPF6016, and EPF6024 devices including the EPF6024AQI208-1N) is hosted at the Intel FPGA archive at https://www.altera.com/literature/ds/dsf6000.pdf. The document includes pinout tables, DC/AC switching characteristics, configuration timing, and JTAG BSDL files. Always cross-reference the latest revision letter when validating timing parameters.
Where can I find the EPF6024AQI208-1N pinout?
The EPF6024AQI208-1N pinout is published in the FLEX 6000 datasheet, Chapter 7, in the '208-Pin PQFP Pin-Out Tables' section. The 208-pin PQFP uses the standard Altera pin numbering convention with pin 1 at the top-left marker dot. Dedicated configuration pins (nCONFIG, nSTATUS, CONF_DONE, DCLK, DATA0) are clustered on the package edge for predictable PCB routing.
How do I configure the EPF6024AQI208-1N?
Configure the EPF6024AQI208-1N with a serial configuration EPROM such as the EPC2 or EPC8, or via JTAG using a ByteBlasterMV or USB-Blaster download cable. On power-up the FLEX 6000 device reads configuration data from the EPC device on the rising edge of DCLK, then releases CONF_DONE to enter user mode. The MSEL[2:0] pins select between AS, AP, PS, and JTAG configuration modes.
Which software is used to program the EPF6024AQI208-1N?
The EPF6024AQI208-1N is programmed with the legacy Altera Quartus II design software (versions 9.0 through 13.0sp1 support the FLEX 6000 family). Modern Quartus Prime releases have dropped FLEX 6000 support, so designers maintaining legacy boards must retain a Quartus II virtual machine or use the Altera Subscription Edition archive from the Intel FPGA support portal.
What are the best drop-in replacements for the EPF6024AQI208-1N?
The best drop-in replacements for the EPF6024AQI208-1N are the EPF6024AQC208-1N (commercial temperature grade, same PQFP-208 footprint, identical die), the EPF6024AQI208-1 (lead-free industrial variant of the same die), and other FLEX 6000 family members such as the EPF6016AQC208-3 (16K gates in the same PQFP-208 outline, lower logic density). All retain the same 208-pin pinout, JTAG chain, and configuration interface.
Is the EPF6024AQI208-1N suitable for new industrial designs in 2026?
Intel recommends against using the EPF6024AQI208-1N for new industrial designs because the device has been obsolete for several years and lacks long-term supply guarantees. For new projects, select a Cyclone IV/V or MAX 10 device with active lifecycle support, modern Quartus Prime toolchain compatibility, and RoHS/REACH compliance documentation. Reserve the EPF6024AQI208-1N for maintaining existing equipment where form-fit-function replacement is mandatory.

Selection Guide

Choose the EPF6024AQI208-1N when you need the full 24,000-gate FLEX 6000 capacity, industrial -40 C to +85 C temperature range, and the 208-pin PQFP footprint in a legacy or industrial-control application. For new designs, however, prefer a Cyclone IV or MAX 10 device to avoid obsolete-part risk. Select the EPF6024AQC208-1N as a same-package drop-in if your environment stays within 0 C to +70 C, the EPF6024AQI208-1 for an industrial alternative in a different reel code, the EPF6024AQC208-2 if your timing budget tolerates a slower speed grade, and the EPF6016AQC208-3 if your logic utilization is below 1,320 LEs and you want the lowest broker price. All five alternatives share the identical PQFP-208 pinout, allowing PCB-rework-free migration.

Key Differentiators

  • Industrial temperature grade with full 24K-gate capacity in PQFP-208 (vs EPF6024AQC208-1N)
  • Full 24K-gate logic capacity vs 16K on smaller family member (vs EPF6016AQC208-3)
  • Faster -1 speed grade at 172 MHz versus -2/-3 bins (vs EPF6024AQC208-2)

Design Notes

Estimated: at 3.3 V nominal supply with all 171 I/O switching at 50 MHz into 35 pF loads, the EPF6024AQI208-1N draws approximately 250 mA (ICCINT ~150 mA + ICCIO ~100 mA). Place one 0.1 uF X7R ceramic bypass capacitor within 5 mm of every VCCINT and VCCIO pin, plus a single 33 uF tantalum bulk capacitor adjacent to the package. The FLEX 6000 datasheet requires VCCIO ramp-up before VCCINT; use a power-sequencer IC or an RC delay on the VCCINT regulator enable to enforce this order.

Route the configuration bus (nCONFIG, nSTATUS, CONF_DONE, DCLK, DATA0) on the same PCB layer as the FPGA with no vias where possible; keep the trace length below 50 mm and isolate them from switching I/O runs to avoid coupling during programming. The 208-pin PQFP land pattern requires a 28 mm x 28 mm footprint with 0.65 mm lead pitch; use a 4-layer board with continuous VCC and GND planes directly under the device to provide a low-impedance return path for the four PLL analog supplies.

Do not attempt to program a FLEX 6000 device with modern Quartus Prime; the last version supporting FLEX 6000 is Quartus II 13.0sp1, and the legacy USB-Blaster driver is incompatible with Windows 10 64-bit without manual INF signing. For JTAG programming on legacy boards, use the parallel-port ByteBlasterMV with a Quartus II 9.1 SP2 virtual machine, or pre-program an EPC2/EPC8 configuration EPROM that is soldered to the board. New designs should migrate to a Cyclone IV or MAX 10 device to avoid these toolchain complications.

Estimated: at ambient +70 C with 1 W dissipation, the junction temperature of a PQFP-208 package rises roughly 35 C above ambient based on a typical theta_JA of 35 C/W. Keep the device below +85 C ambient with at least 25 CFM of forced-air cooling across the package, or add a small clip-on heatsink. Avoid placing the FPGA adjacent to high-power DC-DC converters; thermal coupling from a 2 W switcher can push the junction 10-15 C above ambient.
