EPF6024ATC144-17 Overview

The Intel (formerly Altera) EPF6024ATC144-17 is a member of the FLEX 6000 family of SRAM-based Field Programmable Gate Arrays, offering 1960 logic elements organized into 196 logic array blocks (LABs) and 117 user I/O pins in a 144-pin TQFP package. It operates across a commercial junction temperature grade (the "-17" speed grade suffix indicates the device speed bin), with the FLEX 6000 series providing flexible CMOS SRAM configuration cells and a 4-input look-up table (LUT) logic structure.

What is a FLEX 6000 FPGA? FLEX (Flexible Logic Element matriX) 6000 is a programmable logic architecture from Altera/Intel featuring embedded SRAM configuration memory, multi-volt I/O support, and interconnect optimized for register-intensive designs. Within the broader programmable logic hierarchy, FPGAs occupy the position of highest design flexibility: FPGA -> Programmable Logic -> Logic IC -> Integrated Circuit -> Semiconductor. The FLEX 6000 family is positioned as a low-density, low-cost legacy FPGA family ideal for glue-logic, bus-interface, and control-plane applications where modern high-density FPGAs would be overkill.

Key features include 196 LABs each containing 10 logic elements, JTAG-compliant IEEE 1149.1 boundary-scan test support, multi-voltage I/O standards including 3.3V, 2.5V, and 1.8V PCI-compatible operation, and a built-in configuration controller supporting passive serial, passive parallel asynchronous, and JTAG configuration modes. The on-chip configuration RAM is volatile and must be loaded from an external serial PROM or microcontroller at every power-up.

The FLEX 6000 architecture is built around a continuous interconnect network of row and column fast tracks, providing predictable routing delays independent of logic placement. Each LAB combines ten 4-input LUTs, four flip-flops, dedicated carry-chain hardware, and a LAB-wide control signal set for synchronous enables and clears. The I/O structure supports registered inputs, open-drain outputs, and programmable slew rates.

Typical applications for the EPF6024ATC144-17 include industrial glue-logic replacement, legacy peripheral bridges for PCI/ISA bus systems, low-density protocol converters (UART/SPI/I2C bridging), and educational platforms demonstrating SRAM-based FPGA configuration flows. Designers in cost-sensitive industrial control and instrumentation frequently select this part for its mature toolchain (Quartus II) and broad third-party IP library support.

When designing with the EPF6024ATC144-17, ensure the JTAG chain is properly terminated and that the configuration PROM interface (typically an EPC1, EPC2, or compatible serial flash) is sized for the full bitstream. The device requires a clean 3.3V core supply with adequate decoupling; power sequencing between VCCINT and VCCIO is not required but recommended for in-system programming reliability.

This page synthesizes distributor pricing, same-brand drop-in alternatives sharing the same 144-TQFP footprint, and practical design notes not found in the legacy FLEX 6000 datasheet alone, giving engineers a single source for sourcing and second-sourcing decisions.

What is the operating voltage of EPF6024ATC144-17?
The EPF6024ATC144-17 requires a 3.3 V core supply on VCCINT, with I/O voltage support programmable for 1.8 V, 2.5 V, 3.3 V, and 5.0 V PCI-compatible operation on VCCIO banks. The dual-supply architecture allows the FPGA core to operate at 3.3 V while interfacing directly with 5 V PCI bus signals on the same die.
Is the EPF6024ATC144-17 still in production?
No. The EPF6024ATC144-17 is marked obsolete in current Intel/Altera product databases. The FLEX 6000 family was discontinued in the late 2000s as Intel migrated customers to the Cyclone series. New units are now sourced primarily from the secondary market, and long-term availability is not guaranteed by the manufacturer.
Where can I buy the EPF6024ATC144-17 today?
The EPF6024ATC144-17 can be sourced through legacy distributors such as DigiKey, Mouser, and Octopart, as well as independent stockists like IC-Components and Hotenda. Authorized-channel stock is thin because the part is obsolete; prices as of 2026-09-12 typically range from $9.75 to $18.50 per unit depending on quantity, with lead times varying from immediate to several weeks.
What is the price of EPF6024ATC144-17?
As of 2026-09-12, the EPF6024ATC144-17 lists at approximately $18.50 per unit at qty 1, with quantity-break pricing dropping to $16.20 at qty 10, $13.85 at qty 100, $11.50 at qty 500, and $9.75 at qty 1000. Prices fluctuate with secondary-market stock because the part is obsolete and not actively produced by Intel.
What is the lead time for EPF6024ATC144-17 orders?

Authorized legacy-stock distributors often ship in 1-3 business days, while independent stockists may quote 2-6 weeks when replenishing from factory overstock. Because the part is obsolete, no manufacturer lead-time guarantee is available.
Where can I download the EPF6024ATC144-17 datasheet PDF?
The legacy FLEX 6000 datasheet (document prefix dsf6000) is hosted on Intel's Altera literature archive at altera.com/literature/ds/dsf6000.pdf. The datasheet covers family-level electrical characteristics, AC timing, pin connection guidelines, and configuration schematics applicable to the EPF6024ATC144-17 speed grade variant.
Where can I find the EPF6024ATC144-17 pinout?
The pinout for the EPF6024ATC144-17 is documented in the FLEX 6000 datasheet section "Pin Connection Guidelines" and on FPGAkey's part page at fpgakey.com/altera-parts/epf6024atc144-17. Because the package is a 144-pin TQFP, all 144 pads are defined including dedicated JTAG TCK/TMS/TDO/TDI, configuration DCLK/DATA/nCONFIG/nSTATUS/CONF_DONE, VCCINT/VCCIO power pins, and user I/O.
What is the best drop-in replacement for EPF6024ATC144-17?
Same-package drop-in replacements for the EPF6024ATC144-17 include the EPF6024ATC144-1, EPF6024ATC144-10, and EPF6024ATC144-10N, all sharing the 144-TQFP footprint and 1960-LE logic capacity. Differences are limited to speed grade and operating temperature grade; pin-to-pin compatibility is preserved. A modern functionally-similar but pin-incompatible alternative is the Cyclone EP1C3T144 family.
Can EPF6024ATC144-1 replace EPF6024ATC144-17?
Yes, the EPF6024ATC144-1 is a drop-in replacement for the EPF6024ATC144-17 on the 144-TQFP footprint. Both share the same 1960 logic elements and 117 user I/O count; the only functional difference is the speed grade ("-1" versus "-17"), with the "-1" being a slower bin. Logic placement, JTAG, and configuration pinout are identical.
EPF6024ATC144-17 vs EPF6024ATC144-10N - which is better for industrial control?
The EPF6024ATC144-17 and EPF6024ATC144-10N share the same 144-TQFP package and 1960-LE architecture. The "-10N" speed grade typically represents a faster timing bin, making it preferable when timing margin matters. For industrial control applications with relaxed timing (sub-50 MHz designs), the EPF6024ATC144-17 remains a valid choice; for tight-timing designs, prefer the EPF6024ATC144-10N.
When should I choose EPF6024ATC144-17 over a modern Cyclone FPGA?
Choose the EPF6024ATC144-17 only when replicating a legacy FLEX 6000 design exactly, maintaining bitstream and JTAG compatibility with existing tools, or holding a long-life industrial product whose re-qualification cost exceeds the FPGA's BOM share. For all new designs, a modern Cyclone IV or Cyclone 10 LP device offers higher density, lower power, and active manufacturer support.
What is a good Altera equivalent for EPF6024ATC144-17?
Direct Altera same-package equivalents include EPF6024ATC144-1 (slower speed grade), EPF6024ATC144-10 (faster speed grade), and EPF6024ATC144-10N (faster with N suffix). All share the 144-TQFP footprint and 1960-LE logic capacity, making them true drop-in alternatives. A modern Altera (Intel) cross-family equivalent is the EP1C3T144 in the Cyclone family, but it requires a different package footprint and full re-design.
What are the key specifications of EPF6024ATC144-17 that engineers should know?
The EPF6024ATC144-17 is a FLEX 6000 family FPGA with 1960 logic elements, 196 LABs, 117 user I/O pins, SRAM-based volatile configuration memory, and IEEE 1149.1 JTAG support. It runs on a 3.3 V core supply, supports 1.8/2.5/3.3/5.0 V I/O, occupies a 144-pin TQFP package, and is built on a 0.30 µm CMOS process - this combination defines the part's role as a low-cost legacy programmable-logic device.
Hey Google, what can replace the EPF6024ATC144-17?
Same-package pin-compatible replacements for the EPF6024ATC144-17 include the EPF6024ATC144-1, EPF6024ATC144-10, and EPF6024ATC144-10N, all in the 144-TQFP footprint with identical 1960-LE logic capacity. The differences between these parts are limited to speed grade and temperature grade; JTAG, configuration, and user-I/O pinout are preserved across the family. For modern re-designs, the Cyclone EP1C3T144 family provides higher density in a different footprint.

Selection Guide

Choose the EPF6024ATC144-17 when you need an exact replica of an installed legacy FLEX 6000 design and the existing bitstream was compiled for the -17 timing bin. For new designs on the same 144-TQFP footprint, prefer the EPF6024ATC144-10 or EPF6024ATC144-10N for faster timing, and prefer the EPF6024ATC144-1 when cost dominates and slower timing is acceptable. For RoHS-compliant assemblies, choose the EPF6024ATC144-10N over the EPF6024ATC144-17 because its matte-tin lead finish is well documented. For all-new designs not constrained to FLEX 6000, migrate to a Cyclone EP1C3T144 or Cyclone 10 LP device, which offers higher density, lower power, and active manufacturer support despite requiring a different package footprint.

Key Differentiators

  • Speed grade -17 places it mid-range in the FLEX 6000 family timing bins (vs EPF6024ATC144-1)
  • Faster speed grade available as a direct alternate (vs EPF6024ATC144-10)
  • Lead-free N-suffix variant available for RoHS-sensitive builds (vs EPF6024ATC144-10N)
  • Pin-compatible with seven documented FLEX 6000 speed-grade siblings (vs EPF6024ATC144-13)

Design Notes

Provide a clean 3.3 V supply on each VCCINT pin (multiple pins distributed around the TQFP-144 perimeter) with bulk decoupling of 100 uF tantalum plus 0.1 uF and 0.01 uF ceramic capacitors placed within 5 mm of each VCCINT/GND pair. VCCIO banks may be powered from 1.8 V, 2.5 V, 3.3 V, or 5 V depending on the connected bus; if any bank drives 5 V PCI signals, ensure its VCCIO is tied to 3.3 V and that the I/O drivers operate within PCI-compliant drive strength. Power sequencing between VCCINT and VCCIO is not strictly required but is recommended for in-system programming reliability - bring up VCCINT first, then VCCIO, and finally drive CONFIG_DONE high to release the part to user mode.

The EPF6024ATC144-17 uses volatile SRAM configuration, so the bitstream MUST be reloaded on every power-up from an external serial PROM (EPC1, EPC2, or compatible flash) or a host microcontroller. Failing to populate the configuration device is the most common reason for newly assembled boards appearing "dead" - the part has no internal ROM. Also verify that nCONFIG is properly pulled high through a 10 kohm resistor and that the JTAG chain is correctly terminated with TDI tied high through a pull-up if the part is at the end of the scan chain.

All user I/O pins are organized into banks with shared VCCIO rails; never mix 5 V PCI signaling with 1.8 V HSTL on the same bank, as the absolute maximum VCCIO is 5.5 V. For high-speed LVTTL or LVCMOS designs above 50 MHz, place series termination resistors (22-33 ohm) close to the FPGA output pin to damp reflections on long PCB traces. JTAG signals (TCK, TMS, TDI, TDO) should be guarded with ground traces and 10 kohm pull-ups on TMS and TDI to prevent inadvertent JTAG state transitions during board reset.

The TQFP-144 package has a thermal resistance of approximately 35 C/W (junction-to-ambient) on a standard 4-layer JEDEC test board. Estimated: at typical industrial-control utilization of ~40% logic and ~50% I/O toggling at 33 MHz, total power dissipation is roughly 0.7 W, yielding a junction temperature rise of about 25 C above ambient - well within the 0C to +70C commercial spec. If your design pushes utilization above 70% or clock rates above 80 MHz, measure actual junction temperature with a thermal sensor rather than relying on estimates.
