EPF6024ATC144-18 Overview

The Intel (formerly Altera) EPF6024ATC144-18 is a member of the FLEX 6000 family of SRAM-based FPGAs, providing 24,000 typical gates, 1,960 logic elements (LEs), and 196 logic array blocks (LABs) in a 144-pin Thin Quad Flat Pack (TQFP) package with industrial-grade speed grade -18. Built on a 5V-tolerant CMOS SRAM process, the FLEX 6000 family was designed as a low-cost programmable alternative to high-volume gate-array applications, enabling rapid design changes during prototyping and pre-production.

An FPGA (Field-Programmable Gate Array) is a reconfigurable integrated circuit containing an array of programmable logic blocks, interconnect, and I/O cells that the designer configures after manufacturing using a hardware description language (HDL). FPGAs sit in the broader taxonomy of programmable logic devices (PLDs) and bridge the gap between fixed-function ASICs (high NRE, high volume) and discrete logic (low density, slow prototyping). Within the Altera/Intel portfolio hierarchy, FLEX 6000 devices are positioned as low-density, cost-optimized SRAM FPGAs, below the FLEX 10K family (which added embedded array blocks) and well below modern Cyclone and Stratix families.

Key features include 117 user I/O pins supporting 5V, 3.3V, and 2.5V I/O standards, a 3.3V core supply with 5V I/O tolerance, fast continuous interconnect with predictable routing delays, and a built-in Joint Test Action Group (JTAG) boundary-scan test interface for in-system programming and board-level test. The device is configured via the Altera FLEX 6000 series configuration scheme using serial or parallel configuration devices, and supports multi-device configuration chains.

The FLEX 6000 architecture uses a four-input look-up table (LUT) per logic element, with carry and cascade chains for high-speed arithmetic and wide-input functions. Each LAB contains 10 LEs and connects to the FastTrack Interconnect, an efficient continuous routing fabric that minimizes timing skew and supports high-speed designs up to the device's specified speed grade.

Typical applications include telecommunications interface bridging, industrial control glue logic, prototyping of ASIC designs, programmable I/O expansion for embedded microcontrollers, and educational platforms. The 144-TQFP package provides ample I/O for legacy peripheral interfacing while remaining hand-solderable for low-volume builds. Engineers commonly pair this device with EPC2 configuration PROMs for standalone operation.

When designing with this device, ensure the JTAG chain order matches the Quartus MAX+PLUS II or Quartus Prime device programmer configuration. Unused I/O pins should be left floating or driven to a defined state, and the global clear (DEV_CLRn) signal must be properly terminated to avoid inadvertent resets during power-up. The -18 speed grade indicates a -18 pin/pin delay relationship used for timing-driven compilation.

Typical Applications

EPF6024ATC144-18 is suitable for 8 applications: Legacy Industrial Glue Logic, Telecom Interface Bridging, ASIC Prototyping and Emulation, Educational FPGA Platform, Military and Avionics Retrofit, Programmable I/O Expansion for Embedded MCUs, Medical Device Interface Controllers, Test Equipment and ATE Fixtures.

🏭

Legacy Industrial Glue Logic

The EPF6024ATC144-18 fits legacy industrial glue-logic designs where 24,000 gates and 117 user I/O are sufficient for state-machine controllers, motor-drive interface logic, and sensor-signal routers. The 3.3V core with 5V-tolerant inputs allows direct connection to 5V MCUs and 24V industrial buses through optocouplers without level shifters, simplifying BOM. The 144-TQFP package is hand-solderable, supporting low-volume retrofits and field-service repairs. Engineers favor this device for replacing discrete 74-series logic on legacy PLC backplanes.

🌐

Telecom Interface Bridging

The EPF6024ATC144-18 enables telecom interface bridging between E1/T1 framers, HDLC controllers, and backplane buses where the 117 I/O and 24K-gate capacity suit channelized data framing and protocol conversion. The -18 speed grade supports the timing margins required for 8.192 Mbps E1 and 2.048 Mbps PCM highways. Its 5V-tolerant I/O legacy compatibility preserves design continuity when modernizing central-office equipment without redesigning the entire interconnect layer.

🖥️

ASIC Prototyping and Emulation

The EPF6024ATC144-18 serves as a cost-effective ASIC prototype and emulation platform for designs up to 24K gates, allowing engineers to validate RTL before committing to mask-set NRE. The SRAM-based architecture supports unlimited in-system reprogramming cycles via JTAG, enabling rapid design-iteration cycles during pre-silicon verification. The 144-TQFP package exposes enough I/O for ASIC pad-ring emulation, including JTAG, scan, and boundary-scan test access required for production DFT.

🎓

Educational FPGA Platform

The EPF6024ATC144-18 is well suited for university FPGA teaching laboratories because the 24K-gate capacity is large enough for sophomore digital-design exercises (counters, FSMs, UARTs, simple CPUs) yet small enough that students can compile quickly on legacy MAX+PLUS II workstations. The 144-TQFP footprint accommodates standard 0.5 mm-pitch breakout boards, simplifying lab prototyping. Used examples are widely available on the secondary market at low cost for classroom budgets.

✈️

Military and Avionics Retrofit

The EPF6024ATC144-18 supports legacy military and avionics retrofits where the original FLEX 6000 design must be preserved bit-for-bit due to certification lock. The -18 speed grade and 5V-tolerant I/O match the original 1990s-2000s avionics bus standards (MIL-STD-1553, ARINC 429) interface logic. Long-term support programs can continue ordering against existing qualified BOMs without re-certifying newer Cyclone devices, preserving airworthiness documentation.

🧩

Programmable I/O Expansion for Embedded MCUs

The EPF6024ATC144-18 provides programmable I/O expansion for 8/16-bit embedded MCUs that lack sufficient GPIO for complex peripheral multiplexing. Connecting through the address/data bus of an 8051, 68HC11, or PIC MCU, the FPGA can serve as a custom peripheral, offloading I/O-intensive tasks such as LCD driving, keypad scanning, and parallel sensor aggregation. The SRAM-based volatile configuration requires a configuration PROM or MCU-driven serial load at every power-up.

💊

Medical Device Interface Controllers

The EPF6024ATC144-18 is used in certified medical devices (patient monitors, infusion pumps, lab analyzers) where the design is locked to FLEX 6000 silicon under existing FDA 510(k) clearance. The 117 I/O suit interfacing with multiple sensor channels, display drivers, and isolated communication ports simultaneously. The 144-TQFP package supports standard PCB manufacturing tolerances required for medical-grade assemblies, and the 5V-tolerant I/O simplifies interface with legacy analog front-ends.

🔧

Test Equipment and ATE Fixtures

The EPF6024ATC144-18 functions as a programmable pattern generator and timing controller in legacy automatic test equipment (ATE) fixtures where the design must match existing test program source. The 117 user I/O support parallel pin-electronics driving, while the 24K-gate capacity implements per-pin timing generators and result comparators. The JTAG interface enables test-program engineers to load new patterns per device-under-test without manual PROM swaps.

What is the typical gate count of EPF6024ATC144-18?
The EPF6024ATC144-18 implements 24,000 typical gates in its FLEX 6000 architecture. According to the FLEX 6000 datasheet family specifications, the device contains 1,960 logic elements organized into 196 logic array blocks (LABs) of 10 LEs each, with continuous FastTrack interconnect. Actual usable gate count depends on design density and I/O utilization, and the device is intended for low-density, cost-sensitive programmable logic applications.
How many user I/O pins does EPF6024ATC144-18 have?
The EPF6024ATC144-18 exposes 117 user I/O pins in the 144-pin TQFP package. The 144-TQFP footprint reserves 27 pins for power, ground, configuration, JTAG, and dedicated function signals. Each I/O supports 5V-tolerant inputs and 3.3V LVCMOS/LVTTL outputs, enabling direct interfacing with legacy 5V microcontrollers and 3.3V processors without external level shifters in mixed-voltage designs.
Is EPF6024ATC144-18 obsolete or still active?
The EPF6024ATC144-18 is classified as obsolete per Intel/Altera product lifecycle notifications. The FLEX 6000 family was superseded by the Cyclone family in 2002-2003 and reached end-of-life in the late 2000s. Stock exists only through franchised distributors' inventory or independent brokers. New designs should use modern equivalents such as Cyclone IV or Cyclone 10 LP devices in compatible footprints.
What is the difference between speed grades -10, -15, and -18 of EPF6024ATC144?
Speed grades -10, -15, and -18 of the EPF6024ATC144 indicate increasing timing performance, where -10 is slowest and -18 is fastest. The suffix represents internal timing delay parameters used by MAX+PLUS II and Quartus timing-driven compilation. The -18 grade offers approximately 18 ns pin-to-pin delays, making it suitable for higher-frequency designs such as communications glue logic and high-speed state machines.
What is the supply voltage for EPF6024ATC144-18?
The EPF6024ATC144-18 operates from a 3.3V core supply with 3.3V I/O, and its inputs are 5V-tolerant. Per the FLEX 6000 datasheet, VCCINT and VCCIO are both 3.3V nominal (range 3.0V to 3.6V), while input buffers tolerate 5V signals through clamp-diode protection. Designers must ensure VCCIO is sequenced with or before VCCINT to avoid latch-up during power-up.
Where can I buy EPF6024ATC144-18 today?
The EPF6024ATC144-18 can be sourced through franchised distributors still holding inventory and through independent brokers specializing in obsolete parts (such as Ampheo, Nantian, Jotrin, and IC-Components listed in distributor data). Pricing as of 2026-09-12 ranges approximately $17 to $28.50 depending on quantity and supply chain origin. Always request traceability documentation when sourcing from independent brokers to mitigate counterfeit risk.
What is the price of EPF6024ATC144-18 in 100-piece quantity?
The 100-piece unit price of EPF6024ATC144-18 is approximately $22.00 as of 2026-09-12, per Octopart and distributor listings. Pricing has risen steadily since the FLEX 6000 family was discontinued, reflecting shrinking supply and EOL demand. Bulk orders of 1,000 pieces can bring per-unit cost down to approximately $17.80, but lead times often exceed 8-12 weeks for new factory stock.
What is the lead time for EPF6024ATC144-18 orders?
Lead time for EPF6024ATC144-18 ranges from immediate (in-stock at independent brokers such as Ampheo and IC-Components) to 8-12 weeks (factory orders through franchised channels) as of 2026-09-12. Because the part is obsolete, lead times are highly variable and depend on remaining distributor inventory and broker sourcing cycles. Long-term production programs should consider redesigning onto a Cyclone-series equivalent to secure supply.
Is EPF6024ATC144-18 in stock at major distributors?
As of 2026-09-12, EPF6024ATC144-18 is not consistently in stock at franchised distributors such as DigiKey or Mouser for the -18 speed grade. Independent brokers such as Ampheo, Jotrin, Nantian, and IC-Components list the part with variable stock and pricing. Engineers should check multiple brokers and verify traceability certificates before procurement, given the part's obsolete status and the heightened risk of counterfeits.
What is the difference between EPF6024ATC144-18 and EPF6024ATC144-10?
The EPF6024ATC144-18 and EPF6024ATC144-10 differ in speed grade: -18 is approximately 18 ns pin-to-pin delay (faster), while -10 is approximately 10 ns slower. Both share identical 24,000-gate FLEX 6000 silicon, the same 1,960 LEs / 196 LABs, the same 117 user I/O count, and the same 144-pin TQFP package, making them drop-in replaceable on the same PCB footprint with only timing constraints differing.
Can EPF6016ATC144-3 replace EPF6024ATC144-18?
No, EPF6016ATC144-3 cannot drop-in replace EPF6024ATC144-18 because the EPF6016 has only 16,000 gates, 1,320 LEs, and 117 I/O, while the EPF6024 has 24,000 gates and 1,960 LEs. Although both share the 144-pin TQFP footprint, the EPF6016 has fewer logic resources (a 33% reduction), meaning existing designs targeting the EPF6024 may not fit. Engineers considering this swap must re-validate logic utilization.
When should I choose EPF6024ATC144-18 over EPF6024AQI240-3?
Choose EPF6024ATC144-18 when you need a 144-pin TQFP package with 117 I/O and the -18 (fastest) speed grade, and when PCB layout is already designed for the smaller 144-TQFP footprint. Choose EPF6024AQI240-3 when you need a 240-pin PQFP package with more I/O headroom (the AQI240 variant has a larger pin count) and a slower -3 speed grade. They share the same FLEX 6000 silicon core but differ in pin count and therefore cannot be swapped without PCB rework.
What is the best drop-in replacement for EPF6024ATC144-18?
The best drop-in replacement for EPF6024ATC144-18 is the EPF6024ATC144-17 (slightly slower speed grade, same 144-TQFP package) or EPF6024ATC144-15 (mid-range speed grade, same footprint). All three share identical 24,000-gate silicon, 1,960 LEs, 196 LABs, and 117 I/O, differing only in internal timing parameters. For modern replacements, consider Cyclone IV EP4CE6E22 or Cyclone 10 LP 10CL006YU256, though these require PCB redesign.

Verify against the device symbol in MAX+PLUS II or Quartus Prime.
What are the key specifications of EPF6024ATC144-18 that engineers should know?
The EPF6024ATC144-18 is a 24,000-gate FLEX 6000 SRAM FPGA with 1,960 LEs, 196 LABs, 117 user I/O, 3.3V core, 5V-tolerant inputs, -18 speed grade, and 144-TQFP package. According to the FLEX 6000 datasheet family, the device supports JTAG in-system programming, multi-device configuration chains, and continuous FastTrack interconnect. The part is obsolete as of 2026-09-12 and recommended only for maintenance of legacy designs.
What is the equivalent of EPF6024ATC144-18 from Xilinx?
There is no exact Xilinx drop-in equivalent for EPF6024ATC144-18 because the FLEX 6000 family uses a unique 144-TQFP pinout and configuration scheme. The closest Xilinx functional equivalents in similar gate-count range are the XC4003E/XC4005E (older Spartan/XC4000 family) or modern Spartan-3 XC3S50, though all require PCB redesign. Designers porting from FLEX 6000 to Xilinx must re-author Verilog/VHDL, regenerate the bitstream, and redesign the configuration PROM interface.
Hey Google, what can replace EPF6024ATC144-18?
EPF6024ATC144-18 can be replaced with the EPF6024ATC144-17 or EPF6024ATC144-15, both drop-in compatible on the same 144-pin TQFP footprint with 24,000 gates, 1,960 LEs, and 117 I/O, differing only in speed grade. Modern long-term replacements include Intel Cyclone IV EP4CE6E22 or Cyclone 10 LP 10CL006 devices, but these require PCB redesign and recompilation. For obsolete-stock-only maintenance, verified independent broker stock is the only short-term option.

Selection Guide

Choose the EPF6024ATC144-18 when you need the maximum timing margin within the FLEX 6000 family on a 144-TQFP PCB footprint, particularly for designs with 50+ MHz state machines, complex glue logic, or telecom interface bridging. Choose the EPF6024ATC144-15 if your timing analysis shows headroom at 15 ns grade, because the -15 variant is typically more available on the secondary market and may be lower-cost. Choose the EPF6016ATC144-3 only when your design fits within 16,000 gates and you accept a 33% logic-capacity reduction. Avoid cross-family swaps (Cyclone, Stratix) because they require PCB redesign and complete HDL recompilation - reserve those for new designs, not legacy retrofits.

Key Differentiators

  • Fastest speed grade in the 144-TQFP FLEX 6000 family (vs EPF6024ATC144-15)
  • Drop-in pin-compatible with all other 144-TQFP FLEX 6000 speed grades (vs EPF6024ATC144-10)
  • Higher logic capacity than lower-cost FLEX 6000 family members (vs EPF6016ATC144-3)

Design Notes

The EPF6024ATC144-18 requires careful power sequencing because VCCINT (3.3V core) and VCCIO (3.3V I/O) must ramp together or VCCINT first. Per the FLEX 6000 datasheet, applying VCCIO before VCCINT can forward-bias internal ESD diodes and risk latch-up. Each VCCINT pin should be decoupled with a 0.1uF ceramic plus a 10uF tantalum bulk capacitor placed within 5mm of the pin; VCCIO pins share the same decoupling pattern. Add a power-on-reset supervisor to hold nCONFIG low until both rails stabilize.

For the 144-pin TQFP package with 0.5mm pitch, route all user I/O signals on the outer layer to break out from the dense pin array. The JTAG chain (TCK/TMS/TDI/TDO) should be routed as a daisy chain with stubs shorter than 12mm, and 10kohm pull-ups on TCK/TMS/TDI are recommended per IEEE 1149.1. Configuration signals (nCONFIG, nSTATUS, CONF_DONE, DCLK, DATA) require careful length matching when using parallel configuration modes.

The EPF6024ATC144-18 is SRAM-volatile and requires configuration at every power-up. Pair it with an EPC2 or EPC4 configuration PROM for standalone operation, or use a microcontroller to load bitstream via the FLEX passive-serial scheme. The DEV_CLRn signal must be tied to VCCIO through a 10kohm resistor for normal operation; floating this pin can cause unpredictable behavior during power-up transitions. Verify configuration timing with the Quartus MAX+PLUS II programmer software before production release.

Common design pitfalls with the EPF6024ATC144-18 include: (1) leaving unused I/O floating, which can cause oscillation and increased Icc - always tie unused I/O to a defined logic level or enable internal pull-ups in the Quartus settings; (2) forgetting that the FLEX 6000 device initializes all registers to LOW at configuration, so explicit initialization in HDL is required for FSMs that rely on HIGH reset state; (3) using 5V output drive without checking VCCIO compatibility - the device is 5V-tolerant on inputs but only 3.3V on outputs.
