EPF6024ATC1442 Overview

The Altera (Intel) EPF6024ATC1442 is a member of the FLEX 6000 family of SRAM-based FPGAs, offering 24,000 equivalent gates and 1,960 logic cells in a 144-pin LQFP (TQFP) package. It operates from a 3.3 V core supply, is fabricated on a 0.42 um CMOS process, and supports internal clock frequencies up to 166.67 MHz for glue-logic, control plane, and bus-interface tasks. The device exposes 117 user I/O pins and integrates 1,960 logic elements (LEs) backed by embedded array blocks (EABs), giving designers a deterministic, non-volatile-by-default logic fabric when paired with an external configuration PROM.

A Field-Programmable Gate Array (FPGA) is a programmable logic device (PLD) family that uses look-up tables (LUTs), programmable interconnect, and configurable I/O cells to implement arbitrary digital logic after fabrication. Within the broader semiconductor taxonomy, an FPGA sits below ASICs (Application-Specific Integrated Circuits) and CPLDs (Complex Programmable Logic Devices) as a flexible, reprogrammable alternative, and is widely used for glue logic, bus bridging, prototyping, low-volume ASIC replacement, and parallel DSP pipelines.

Key specifications include 24,000 system gates, 1,960 logic cells, 117 user I/Os, 196 LABs (logic array blocks), 3.3 V VCCINT, 0.42 um process geometry, 166.67 MHz internal performance, and TQFP-144 surface-mount packaging. The ATC speed grade balances timing margin and cost for industrial-grade designs, while the -2 suffix denotes a specific speed/operating-condition bin per Altera's legacy FLEX 6000 ordering scheme.

Architecturally, the EPF6024ATC1442 uses a SRAM-based configuration cell that must be loaded at every power-up from an external serial or parallel configuration device (such as the EPC2 or EPC8). The 0.42 um CMOS process provides a balance of density and low static power, while the 117 general-purpose I/Os support LVTTL and LVCMOS standards with user-programmable drive strength and slew rate. Embedded array blocks (EABs) provide efficient on-chip RAM and ROM for FIFO and lookup-table implementations, supplementing the distributed logic-element memory.

Typical applications include industrial control and instrumentation, telecom line-card glue logic, legacy PCI/ISA bus bridges, motor-control and factory-automation boards, and cost-sensitive prototyping platforms that still require the flexibility of programmable logic. The 144-pin LQFP footprint is hand-solderable, making the device friendly for prototype rework and low-volume production.

When designing with this part, plan for an external configuration memory and a JTAG chain (IEEE 1149.1) for in-system programming and boundary-scan test. Decouple VCCINT (3.3 V) and VCCIO (per I/O bank) close to the package with 0.1 uF ceramic capacitors, and respect the FLEX 6000 device family power-up sequencing to avoid partial-configuration latch-up.

This page synthesizes distributor pricing, FLEX 6000 family alternatives, and practical design notes not found in the manufacturer datasheet alone - it is built to answer both purchasing and engineering questions for engineers evaluating EPF6024ATC1442 against modern FPGA replacements.

Typical Applications

EPF6024ATC1442 is suitable for 6 applications: Industrial Control and Instrumentation, Telecom Line-Card Glue Logic, Legacy PCI / ISA Bus Bridges, Motor Control and Factory Automation, Low-Volume ASIC Replacement, Prototyping and Educational Platforms.

🏭

Industrial Control and Instrumentation

The EPF6024ATC1442 fits industrial control and instrumentation due to its 24K-gate density, 117 user I/Os, and 166.67 MHz internal performance - enough to integrate encoder counters, PWM generators, and bus bridges in a single chip. Its 0.42 um CMOS core draws relatively low quiescent current and tolerates 3.3 V supply rails commonly found on PLC backplanes and CNC machine controllers. The TQFP-144 package is hand-solder-friendly, easing prototype rework during factory-floor qualification.

🌐

Telecom Line-Card Glue Logic

EPF6024ATC1442 serves well as line-card glue logic in telecom systems, performing bus arbitration, address decoding, and protocol conversion between TDM framers, network processors, and backplane SERDES. Its 117 I/Os comfortably handle address/data multiplexing for legacy H.110 or H-MVIP buses, while the 166.67 MHz internal clock supports 8-bit/16-bit datapath glue at typical telecom frequencies. The 144-LQFP footprint also fits legacy PCI/PMC card area constraints.

🖥️

Legacy PCI / ISA Bus Bridges

EPF6024ATC1442 is widely deployed in legacy PCI / ISA bridge designs where it implements target/initiator state machines, address decoding, and interrupt routing. The 24K gates are sufficient for a typical 32-bit PCI target with DMA support, while the 117 I/Os leave headroom for ISA bus and side-band signals. Designers can preserve legacy motherboard layouts because the 144-LQFP footprint is compatible with the same land pattern used by many older glue-logic FPGAs.

🏭

Motor Control and Factory Automation

In motor control and factory automation, EPF6024ATC1442 acts as the central logic hub for sensor feedback decoding, PWM generation, and fieldbus protocol termination. The 166.67 MHz internal clock supports deterministic sampling of quadrature encoders and sigma-delta modulator data, while the 117 I/Os allow direct connection to multi-axis stepper/servo drivers. The industrial ATC speed grade is rated for typical factory-floor ambient conditions.

🔧

Low-Volume ASIC Replacement

EPF6024ATC1442 is a cost-effective solution for low-volume ASIC replacement when NRE costs of an ASIC are prohibitive. With 24K gates it can absorb moderate-complexity glue-logic, peripheral controllers, or custom interfaces, while the SRAM-based configuration enables last-minute design revisions without re-spinning silicon. The 144-LQFP package is broadly second-sourced and stocked in the broker/legacy channels, easing long-tail lifecycle concerns.

📚

Prototyping and Educational Platforms

Educational labs and prototyping boards have used EPF6024ATC1442 to teach digital design, bus protocols, and configuration flows. Its TQFP-144 footprint fits 0.5 mm-pitch breadboard adapters, making it practical for hand-soldered student projects. The Quartus II Web Edition toolchain (legacy) supports the part free of charge, and a wealth of reference designs from the FLEX 6000 family remain available in Altera's documentation archive.

What is the logic density of EPF6024ATC1442?
The EPF6024ATC1442 contains 1,960 logic elements (cells) and 24,000 equivalent system gates in the Altera FLEX 6000 family. According to Altera's FLEX 6000 device overview, this places it above EPF6010 (10K gates, ~880 cells) and EPF6016 (16K gates, ~1,320 cells) but below EPF6024A variants in higher-density packages, making it suitable for mid-density glue-logic and bus-bridge designs.
How many user I/O pins does EPF6024ATC1442 expose?
The EPF6024ATC1442 provides 117 user I/O pins in the 144-pin LQFP (TQFP-144) package. Per Heisener's listing and the FLEX 6000 datasheet, this is the maximum I/O count for the 144-pin LQFP footprint; pin-compatible EPF6024ATC100 and EPF6024AQI240 variants expose fewer or more I/Os, respectively.
What core supply voltage does EPF6024ATC1442 require?
The EPF6024ATC1442 operates from a 3.3 V core supply (VCCINT) per the FLEX 6000 family datasheet. VCCIO is configured per I/O bank to support LVTTL and LVCMOS interfaces (exact bank tolerance [DATA_NEEDED]). Designers must add 0.1 uF ceramic decoupling capacitors near each VCC pin and respect power-up sequencing to avoid partial-configuration latch-up.
What is the maximum operating frequency of EPF6024ATC1442?
The EPF6024ATC1442 supports internal logic operation up to 166.67 MHz per the Altera FLEX 6000 device family datasheet. Actual system clock rate depends on routing and logic utilization; -2 speed bin parts typically achieve slightly less than -1 bin parts. Use Altera's legacy Quartus II 7.x or later software to verify worst-case timing closure.
Does EPF6024ATC1442 require an external configuration memory?
Yes, the EPF6024ATC1442 is SRAM-based and must be configured at every power-up from an external configuration device such as Altera EPC2, EPC8, or a compatible parallel/serial PROM. Per FLEX 6000 family documentation, JTAG (IEEE 1149.1) is supported for in-system programming and boundary-scan. Without valid configuration the I/O pins default to tri-state.
Is EPF6024ATC1442 still in production?
No, the EPF6024ATC1442 is marked obsolete / End-of-Life (EOL). The Altera FLEX 6000 family has been superseded by Cyclone, MAX II, and MAX V CPLDs/FPGAs for new designs. Verified Web Data from Heisener lists the part as 'For Reference Only', indicating last-time-buy stock is the typical supply path. Inventory at distributors such as Heisener, Jotrin, and OEMstron ranges from hundreds to thousands of units (6,016-6,256 pcs in the most recent listings).
What is the difference between EPF6024ATC1442 and EPF6024ATC144-2?
The EPF6024ATC1442 and EPF6024ATC144-2 are alternate orderings for the same Altera FLEX 6000 device (24K gates, 1,960 cells, 144-LQFP, -2 speed bin). According to distributor listings, 'EPF6024ATC1442' and 'EPF6024ATC144-2' both resolve to the same die/package. Verify against your distributor's part-number cross-reference tool before ordering to avoid mismatched expectations.

What is the lead time for EPF6024ATC1442 orders?
Lead time for EPF6024ATC1442 is 'To be Confirmed' or 'Can Ship Immediately' depending on stock. Heisener's listing states estimated delivery of Jul 16 - Jul 21 (or Apr 11 - Apr 16 in another listing) with the option of expedited shipping. Because the part is obsolete, lead time is best confirmed at order entry; expect longer lead times for higher quantities (>500 pcs).
EPF6024ATC1442 vs EPF6024AQI240-2 - which should I use?
EPF6024ATC1442 (144-LQFP, ATC grade) and EPF6024AQI240-2 (240-pin PQFP, AQI grade) are pin-incompatible due to different packages (144 vs 240 pins). Choose EPF6024ATC1442 if your PCB uses the 144-LQFP footprint and you need ~117 I/Os. Choose EPF6024AQI240-2 only if you can rework the PCB to the 240-pin PQFP land pattern and need more I/O; otherwise the 144-LQFP variant is the drop-in path.
What is the best drop-in replacement for EPF6024ATC1442?
The best drop-in replacement for EPF6024ATC1442 in the 144-LQFP package is EPF6024ATC144-2 (the dash-form ordering code for the same die). Both share the 144-LQFP footprint, ATC speed grade, and 117 I/O count. Other drop-in alternatives in the same footprint include EPF6024ATC144-1 (slower speed bin) and EPF6016ATC144-2 (lower-density 16K-gate option). Note that EPF6024AQI240 variants are NOT drop-in due to package difference.
Is EPF6024ATC1442 suitable for new designs in 2026?
No, EPF6024ATC1442 is not recommended for new designs in 2026. The FLEX 6000 family is obsolete and replaced by Intel/Altera Cyclone II/III/IV and MAX II/IV/V/V CPLD families, which offer lower power, lower cost per LE, modern toolchains (Quartus Prime), and a longer lifecycle commitment. Use EPF6024ATC1442 only to support legacy equipment where a redesign is not feasible, or to bridge a transition to a modern Cyclone or MAX II CPLD.
Where to download the EPF6024ATC1442 datasheet PDF?
The EPF6024ATC1442 datasheet is hosted in the Altera FLEX 6000 Device Family Data Sheet (document covers the entire family including EPF6010, EPF6016, and EPF6024).

Use the Altera Device Family Overview for architecture details and the legacy Quartus II device support files for software compatibility.
Where to find the EPF6024ATC1442 pinout and package drawing?
The EPF6024ATC1442 pinout and TQFP-144 mechanical drawing are in the Altera FLEX 6000 Device Family Data Sheet, in the 'Package Information' section for the 144-pin LQFP (TQFP-144) variant. The same package is shared across all FLEX 6000 family members in 144-pin LQFP (EPF6010ATC144-x, EPF6016ATC144-x, EPF6024ATC144-x). Pin 1 location follows the standard TQFP convention (top-left with the dot marker).
Can EPF6016ATC144-2 replace EPF6024ATC1442?
Yes, EPF6016ATC144-2 is a pin-compatible drop-in replacement in the 144-LQFP package, but with reduced logic density: 1,320 logic cells and 16K gates vs 1,960 cells and 24K gates on EPF6024ATC1442. Use EPF6016ATC144-2 only when your design fits within the 16K-gate budget. Per Altera's FLEX 6000 datasheet, both share the same TQFP-144 footprint, JTAG chain, configuration interface, and JTAG programming flow - making them mechanically interchangeable.

Selection Guide

Choose EPF6024ATC1442 when you need a 24K-gate, 117-I/O FLEX 6000 FPGA in the 144-LQFP package for legacy industrial, telecom, or glue-logic designs and have already validated the Altera toolchain. Choose EPF6024ATC144-2 (the dash-form) for the same part via a different ordering code - both are electrically identical. Choose EPF6024ATC144-1 if your design has timing slack and you want a slightly cheaper, slower speed bin. Choose EPF6016ATC144-2 or EPF6010ATC144-2 only when your design fits within their smaller logic budgets. Avoid EPF6024AQI240-x variants unless you can rework the PCB to the 240-pin PQFP footprint. For new designs in 2026, prefer a Cyclone II/III/IV FPGA or MAX II/IV/V CPLD instead - the FLEX 6000 family is obsolete, has limited long-term support, and is increasingly expensive to source.

Key Differentiators

  • Maximum density in FLEX 6000 family within the 144-LQFP footprint (vs EPF6016ATC144-2)
  • ATC industrial speed grade (-2 bin) balances timing margin and cost (vs EPF6024ATC144-1)
  • 144-LQFP package is hand-solder-friendly versus PQFP/BGA alternatives (vs EPF6024AQI240-2)
  • Higher 166.67 MHz internal performance for glue-logic timing closure (vs EPF6024ATC144-10)

Design Notes

EPF6024ATC1442 requires a clean 3.3 V VCCINT rail; place a 0.1 uF ceramic decoupling capacitor close to every VCCINT pin and a bulk 10-47 uF tantalum or polymer capacitor at the board's 3.3 V entry. VCCIO is configured per bank - if your design mixes 3.3 V and 5 V peripherals, plan for two independent VCCIO rails (banks 1/4 at 3.3 V, banks 2/3 at 5 V, for example) and isolate them with ferrite beads. Power-up sequencing per the FLEX 6000 datasheet must hold the device in reset until VCCINT and VCCIO are stable to avoid partial-configuration latch-up.

For the 144-LQFP (0.5 mm pitch) footprint, use 0.127 mm (5 mil) traces with 0.2 mm (8 mil) spacing on outer layers and a 4-layer stack-up with continuous VCCINT/GND planes for the inner layers. Place the EPC2/EPC8 configuration PROM within 5 cm of the FLEX 6000 device to keep the DCLK/Data0 traces short and matched; long configuration traces are a common source of intermittent configuration failures. Reserve a 4-pin header for JTAG (TDI, TMS, TCK, TDO) on the PCB for boundary-scan and ISP programming.

The most common pitfalls with EPF6024ATC1442 designs are: (1) confusing 'EPF6024ATC1442' with the dash-form 'EPF6024ATC144-2' (they are the same part - confirm with your distributor); (2) omitting the external configuration PROM and assuming the device retains its pattern after power-down (it does not - FLEX 6000 is SRAM-based); (3) using an EPC1 instead of EPC2/EPC8 for larger FLEX 6000 bitstreams (EPC1 is too small for EPF6024ATC1442); (4) leaving CONF_DONE floating (it is open-drain and must be pulled high); (5) choosing an EPF6024AQI240 variant when the PCB was laid out for 144-LQFP (240-pin PQFP requires re-spinning the board).
