EPF6024ATC144-2N Overview

The Intel (formerly Altera) EPF6024ATC144-2N is a FLEX 6000 family Field Programmable Gate Array (FPGA) featuring 24,000 gates, 1,960 logic cells, and 117 user I/Os in a 144-pin TQFP package. It is built on a 0.42 µm SRAM-based process and supports a maximum internal frequency of 166.67 MHz at a 3.3 V supply. The 'A' speed grade and 'C' commercial temperature range (0°C to 85°C) make this part suitable for mainstream digital logic designs.

An FPGA (Field Programmable Gate Array) is a type of programmable logic device (PLD) that allows designers to configure digital logic functions after manufacture. FPGAs occupy the middle ground between fixed-function ASICs and software-driven microcontrollers, offering hardware-level parallelism for high-throughput tasks. Within Intel's product hierarchy, the FLEX 6000 family sits as a low-cost, SRAM-based logic solution beneath the more capable FLEX 10K and APEX families.

Key features of the EPF6024ATC144-2N include 196 logic array blocks (LABs), 117 general-purpose I/O pins, embedded SRAM-based configuration memory, and an interleaved LAB architecture that improves fitting efficiency. The device supports in-system programmability via a serial configuration interface and operates from a single 3.3 V supply, simplifying board-level power design.

The architecture combines four-input look-up tables (LUTs) per logic element, dedicated carry chains for arithmetic, and a continuous FastTrack Interconnect routing fabric. This combination provides predictable timing and fast compile cycles, which is why FLEX 6000 devices remained popular for glue logic, bus interfacing, and state-machine prototyping well into the 2010s.

Typical applications include telecommunications infrastructure, industrial control systems, consumer electronics glue logic, and legacy digital signal processing front-ends. The 144-TQFP package is a familiar surface-mount footprint that supports standard reflow soldering and hand-rework, which simplifies prototyping and field upgrades.

When designing with this FPGA, engineers should note that configuration data must be loaded from an external EPROM or flash on every power-up because the SRAM cells are volatile. JTAG boundary-scan and IEEE 1532 in-system programmability are supported, enabling rapid iteration during development.

This page consolidates distributor pricing, drop-in alternatives in the 144-TQFP footprint, and engineering design notes that go beyond the manufacturer datasheet, giving procurement teams and design engineers a single source for evaluation and sourcing.

What is the gate count and logic capacity of EPF6024ATC144-2N?
The EPF6024ATC144-2N contains 24,000 typical gates and 1,960 logic cells organized into 196 logic array blocks (LABs). According to the Altera FLEX 6000 datasheet, this positions the device in the low-density FPGA category. It is well-suited for glue logic, state-machine implementation, and bus-interface bridging tasks, but it is not appropriate for designs requiring high-density DSP blocks or embedded multipliers.
What package does EPF6024ATC144-2N use and how many pins does it have?
The EPF6024ATC144-2N is housed in a 144-pin Thin Quad Flat Pack (TQFP-144) with a maximum of 117 user I/O pins. The remaining pins are dedicated to power, ground, JTAG, and configuration signals. TQFP packages are surface-mount and have gull-wing leads on all four sides, making the part compatible with standard reflow soldering and hand rework.
Is EPF6024ATC144-2N still in production or is it obsolete?
The EPF6024ATC144-2N is listed as obsolete by most major distributors. The original FLEX 6000 family was introduced in the late 1990s and has since been discontinued in favor of newer Intel/Altera FPGA families such as Cyclone and MAX series. Engineers maintaining legacy designs can still source stock from authorized distributors and brokers, but long-term procurement planning should account for limited and dwindling inventory.
What is the operating voltage and frequency of EPF6024ATC144-2N?
The EPF6024ATC144-2N operates from a single 3.3 V supply and supports internal logic frequencies up to 166.67 MHz in the 'A' speed grade. The I/O banks are 3.3 V compatible, allowing direct interfacing with TTL and 3.3 V CMOS logic families without level shifters. Higher-frequency operation requires careful PCB layout and adherence to the impedance guidelines in the FLEX 6000 datasheet.
Where can I download the EPF6024ATC144-2N datasheet PDF?
The official FLEX 6000 family datasheet is hosted on Alldatasheet at the URL linked in this product record. The document covers 52 pages of detailed specifications including DC characteristics, AC timing parameters, configuration modes, and package drawings. Always cross-reference the latest revision published by Intel (which absorbed Altera in 2015) for any errata or revisions affecting the FLEX 6000 family.
What is the difference between EPF6024ATC144-2N and EPF6024ATC144-2?
The EPF6024ATC144-2 and EPF6024ATC144-2N are functionally identical FLEX 6000 devices in the 144-TQFP package with the same -2 speed/density code. The trailing 'N' suffix on this part typically denotes lead-free or RoHS-compliant terminal finish, while the bare -2 variant may use a SnPb finish. Designers should verify the exact terminal-finish code with the manufacturer datasheet before substituting.
Where to buy EPF6024ATC144-2N online at the best price?
As of 2026-09-12, the EPF6024ATC144-2N is available through major distributors including DigiKey, Mouser, Octopart-listed brokers, and XAIPART. Because the part is obsolete, prices fluctuate significantly based on remaining stock and wafer allocation. The current qty-1 reference price is approximately $38.50 USD, with volume discounts available at 100-piece and 1000-piece breaks. Always request a fresh quote for production orders.
What is the lead time for EPF6024ATC144-2N orders?
Lead times for the obsolete EPF6024ATC144-2N depend on remaining distributor stock and the order quantity. Small-quantity orders from authorized brokers typically ship within 2-4 weeks. Large orders of 1,000 pieces or more may require 8-12 weeks if stock must be allocated from multiple channels. Engineering teams are advised to qualify second-source alternatives in advance to mitigate supply-chain risk.
Is EPF6024ATC144-2N in stock at major distributors?
Stock levels for EPF6024ATC144-2N are limited as of 2026-09-12 due to its obsolete lifecycle status. DigiKey, Mouser, and Octopart-listed distributors show sporadic inventory. Procurement teams should not rely on real-time distributor stock and should plan for last-time-buy orders or transition to newer FLEX-family equivalents. Cross-checking XAIPART's live inventory is recommended for urgent requirements.
What is the best drop-in replacement for EPF6024ATC144-2N in a 144-TQFP footprint?
Drop-in replacements for the EPF6024ATC144-2N in the 144-TQFP footprint include the EPF6024ATC144-2 (same family, different terminal finish), EPF6024ATC144-1, EPF6024ATC144-1N, and EPF6024ATC144-3 speed grades. These parts share the same pinout and configuration memory format, allowing them to be used as functional replacements with the same bitstream. For new designs, consider migrating to a Cyclone III or Cyclone IV device in a compatible footprint.
Can EPF6016ATC144-2N replace EPF6024ATC144-2N in an existing design?
The EPF6016ATC144-2N is NOT a drop-in replacement for the EPF6024ATC144-2N. While both share the 144-TQFP package, the EPF6016 has 16,000 gates versus 24,000 gates, fewer LABs, and reduced logic capacity. Replacing one with the other would require re-synthesizing the bitstream and may not fit the original design. Engineers should choose a part from the same 6024-density family for true compatibility.
EPF6024ATC144-2N vs Cyclone II EP2C5 - which is better for new designs?
The EPF6024ATC144-2N is obsolete and is not recommended for new designs. The Cyclone II EP2C5 (or modern Cyclone IV EP4CE6) is a vastly superior replacement offering 4,608 logic elements, embedded multipliers, more RAM, and lower core voltage. Although the package pinout differs and a PCB redesign is required, the Cyclone family provides 5-10x the logic capacity at comparable cost and remains in active production.
When should I choose EPF6024ATC144-2N over a newer Intel FPGA?
Choose the EPF6024ATC144-2N only for sustaining legacy designs where a board redesign is not feasible, where the existing bitstream must run unchanged, or where long-term inventory has already been secured. For new designs, prefer the active Cyclone IV, Cyclone V, or MAX 10 families, which provide better performance, lower power, modern toolchain support, and continued manufacturer warranty.
What configuration memory does EPF6024ATC144-2N use?
The EPF6024ATC144-2N uses SRAM-based configuration memory, which is volatile and must be reloaded from an external non-volatile source (such as an EPC configuration EPROM or flash) on every power-up. This enables unlimited reprogramming cycles and in-system programming via JTAG, but it requires additional board space for the configuration storage device. Designers should follow the configuration scheme guidelines in the FLEX 6000 datasheet.
Where to find the pinout diagram for EPF6024ATC144-2N?
The pinout for EPF6024ATC144-2N is published in the FLEX 6000 family datasheet on Alldatasheet and the original Altera/Intel documentation. The 144-TQFP package follows standard JEDEC pin numbering with pin 1 located by the indicator dot. User I/O assignments are pinout-specific to the device variant; the datasheet's package diagrams section contains the full ball/pin map with signal names and bank assignments.

Selection Guide

Choose the EPF6024ATC144-2N for sustaining legacy designs where board rework is not feasible, the existing bitstream must run unchanged, or where long-term inventory has been secured. Select the EPF6024ATC144-2 for non-RoHS applications requiring SnPb finish. Use the EPF6024ATC144-3N if higher speed-grade timing margin is required, or the EPF6024ATC144-1N when timing is non-critical and cost is paramount. For new designs, do not start with FLEX 6000 — the family is obsolete and lacks modern features such as embedded multipliers, PLLs, and high-speed transceivers. Migrate to Cyclone IV EP4CE6 (TQFP-144) or MAX 10 (EQFP-144) for active production, modern toolchain support, and 5-10x higher logic density at comparable cost.

Key Differentiators

  • Industry-standard 144-TQFP footprint with established long-term supply (vs EPF6024AFC256-3 (BGA-256))
  • Volatile SRAM configuration supports unlimited reprogramming cycles (vs CPLDs (e.g., MAX 7000 series))
  • 166.67 MHz internal frequency exceeds most legacy glue-logic requirements (vs EPF6016ATC144-2 (16K gates))

Design Notes

The EPF6024ATC144-2N requires a clean 3.3 V supply for both VCCINT (core) and VCCIO (I/O) rails. Place 0.1 µF ceramic decoupling capacitors as close as possible to every VCC pin and add a bulk 10-47 µF tantalum or polymer capacitor near the package. Estimated: at typical 100 MHz toggle rate, this FPGA draws ~150-250 mA core current; budget the regulator for 500 mA peak to handle configuration transients. Add a 10 kΩ pull-up on nCONFIG and a 10 kΩ pull-up on nSTATUS per the FLEX 6000 datasheet recommendation.

The 144-TQFP package has a 0.5 mm pitch and gull-wing leads. Use at least 4-layer PCB stack-up with a dedicated ground plane and a 3.3 V power plane. Maintain 50 Ω controlled impedance for high-speed clock and JTAG signals. Keep configuration signals (DCLK, DATA0, nCONFIG, nSTATUS, CONF_DONE) away from switching I/O traces to prevent crosstalk during configuration. Provide a solid ground return path under the package thermal pad area (although the TQFP has no exposed pad, ensure continuous ground fill underneath).

Configuration memory is volatile SRAM — without an external EPC configuration EPROM or flash, the FPGA will not boot on power-up. Do not omit the configuration device or jumper the JTAG chain incorrectly. MSEL pins must be tied to the correct logic levels for the chosen configuration mode (AS, PS, or JTAG). Estimated: configuration time for a fully populated EPF6024 is ~50-100 ms; allow at least 200 ms margin in system boot sequencing before accessing FPGA-controlled peripherals.

The 144-TQFP package has a typical θJA of approximately 35-45 °C/W in still air. Estimated: at 200 mA core current and 0.42 µm process, internal dissipation is ~660 mW, yielding a 25-30 °C junction temperature rise above ambient. For continuous commercial-temperature operation (0-85°C), no heatsink is required, but ensure adequate airflow in enclosed industrial cabinets. Avoid placing the FPGA directly adjacent to high-heat components such as linear regulators.

JTAG chain integrity is critical for in-system programming and boundary-scan test. Place a 4.7 kΩ pull-up on TCK, TMS, and TDI; place a 4.7 kΩ pull-up on TDO only if it is the last device in the chain. Keep JTAG traces under 6 inches (150 mm) total length and maintain 50 Ω impedance. The FLEX 6000 datasheet recommends routing DCLK away from high-frequency I/O to avoid coupling that could corrupt configuration data.
