EPF6024ATC144-10N Présentation

The Altera (now Intel) EPF6024ATC144-10N is a member of the FLEX 6000 family of SRAM-based Field-Programmable Gate Arrays, providing 1960 logic elements organized as 196 Logic Array Blocks (LABs), 117 user I/O pins, and housed in a 144-pin TQFP (T144) plastic package with a speed grade of -10 (10 ns pin-to-pin delay class). It is fabricated on a 5 V CMOS process with on-chip flash/EPROM configuration support and operates over the commercial 0 C to +70 C junction range.

A Field-Programmable Gate Array (FPGA) is a semiconductor integrated circuit built around an array of configurable logic blocks (CLBs or LABs), programmable interconnect, and I/O cells that the user can define after manufacturing. The FLEX 6000 family sits in Altera's older programmable-logic hierarchy between the classic MAX series and the high-density FLEX 10K/Stratix lines, targeting glue-logic replacement, bus interface bridging, and small-to-medium state-machine consolidation. As a programmable logic device (PLD) family, the EPF6024ATC144-10N belongs to the broader semiconductor category of logic ICs.

Key features include 1960 logic elements, 117 user I/O pins, built-in cascade and carry chains for high-speed arithmetic and wide-input functions, JTAG-based boundary-scan testability, and multi-voltage I/O support allowing mixed 5.0 V / 3.3 V / 2.5 V interface levels. The -10N suffix indicates a -10 speed grade and lead-free (Pb-free) assembly, with the trailing N denoting industrial-temperature material set in some supplier catalogs.

The architecture combines four-input look-up tables (LUTs), dedicated carry chains for fast adders and counters, and cascade chains for wide fan-in functions such as equality comparators. Each LAB contains 10 logic elements (LEs), and dedicated row/column interconnect minimizes routing delay. Embedded SRAM is not part of the FLEX 6000 family, distinguishing it from FLEX 10K; configuration is loaded from external EPROM, flash, or controller over a serial or parallel interface.

Typical applications include bus-interface bridges (e.g., ISA-to-PCI glue logic), peripheral controllers in industrial embedded boards, custom state machines in legacy telecom equipment, prototype ASIC replacement, and parallel I/O expansion for legacy microprocessors. The 144-pin TQFP package is footprint-compatible across the EPF6024ATC144 speed-grade family (-3, -1, -10), enabling drop-in PCB reuse when migrating between speed grades.

When designing with this device, plan for an external configuration memory (serial EEPROM or parallel EPROM) because the FLEX 6000 family is SRAM-based and loses its bitstream on power-down. Observe the 5.0 V core supply requirement (VCCINT), use decoupling per the datasheet's reference design, and verify I/O bank voltages against your bus partner before PCB layout.

This page consolidates drop-in speed-grade alternatives, parametric comparisons, and practical design considerations not always gathered in the original Altera datasheet.

Applications typiques

EPF6024ATC144-10N convient pour 6 applications: Legacy Bus-Interface Bridge, Industrial Embedded Controller, Custom State Machine / ASIC Replacement, Telecom Backplane Glue Logic, Parallel I/O Expansion for Legacy Microprocessors, Test & Measurement Front-End Controller.

🖥️

Legacy Bus-Interface Bridge

The EPF6024ATC144-10N is well-suited as a glue-logic bridge between legacy 5 V buses (ISA, PC/104, VME) and modern 3.3 V peripherals, with 117 user I/Os and four-input LUTs sufficient to implement multiplexers, address decoders, and wait-state generators. The 144-pin TQFP package exposes 117 I/Os while leaving pins for JTAG and configuration. Designers should verify VCCIO bank voltages against the bus partner; the FLEX 6000 supports 5.0 V / 3.3 V / 2.5 V mixed I/O. The 10 ns speed grade is adequate for ISA-style 8-16 MHz bus cycles.

🏭

Industrial Embedded Controller

The EPF6024ATC144-10N serves as a peripheral controller in legacy industrial PC/104 and VME systems, where its 1960 logic elements implement UART/SPI/I2C bridges, custom state machines, and parallel I/O expansion for 80C186/80C188 microprocessors. The 5.0 V VCCINT matches classic industrial CPU rails, eliminating level-shifters on the host bus, while multi-voltage I/O banks let the same part talk to 3.3 V ADC/DAC peripherals. The commercial 0-70 C temperature range suits cabinet-mounted equipment; budget approximately 1 W of board power for a fully utilized design.

🔧

Custom State Machine / ASIC Replacement

With 1960 logic elements and 196 LABs, the EPF6024ATC144-10N consolidates multi-chip 74-series glue logic into a single FPGA, ideal for prototyping ASIC replacements before tape-out. Each LE contains a 4-input LUT plus a programmable register, so a complex state machine with dozens of states and parallel datapath logic fits comfortably. The carry and cascade chains accelerate high-speed arithmetic (counters, adders) and wide-input comparators. Designers migrating from a hard ASIC retain identical I/O behavior while gaining in-system reprogrammability.

🌐

Telecom Backplane Glue Logic

The EPF6024ATC144-10N is commonly deployed as backplane glue logic in legacy telecom shelves - implementing TDM bus arbiters, HDLC channelizers, alarm scanners, and front-panel interface controllers. Its 117 user I/Os are sufficient for 8-bit parallel TDM buses plus auxiliary serial links, and JTAG boundary-scan support simplifies board-level test. The 5 V core matches -48 V telecom brick-derived rails typical in legacy equipment. Migration path to Cyclone IV EP4CE6 is straightforward but requires board redesign due to different I/O bank voltages.

💡

Parallel I/O Expansion for Legacy Microprocessors

The EPF6024ATC144-10N pairs well with classic microprocessors (8086, 68000, Z80) as an external I/O expander and bus decoder, off-loading address decoding, chip-select generation, and parallel-port multiplexing from the CPU. With 117 user I/Os, the part can serve up to 14 8-bit ports plus control logic, all while running at 5 V to match the host CPU. The 10 ns speed grade is fast enough for 10 MHz CPU cycles; for higher CPU clocks, migrate to the -3N or -1N speed grade which retains the same footprint.

📺

Test & Measurement Front-End Controller

The EPF6024ATC144-10N is used as a front-panel controller in bench-top test equipment, multiplexing displays, keypads, GPIB/USB bridges, and ADC/DAC interface logic. Its 1960 logic elements and 117 I/Os handle mid-density instrument front-ends without resorting to a larger FPGA, while JTAG boundary-scan aids in board bring-up. The commercial 0-70 C range suits laboratory environments; for industrial or outdoor test rigs, consider the industrial-grade equivalent. The 144-pin TQFP provides ample ground pins for the analog/digital split-rail layouts typical of instrumentation.

What is the EPF6024ATC144-10N and what family does it belong to?
The EPF6024ATC144-10N is a member of the Altera FLEX 6000 family of SRAM-based Field-Programmable Gate Arrays, providing 1960 logic elements in 196 LABs with 117 user I/Os in a 144-pin TQFP package. The -10N suffix denotes a -10 speed grade (10 ns pin-to-pin delay class) and lead-free assembly. According to distributor listings, the part is now classified as obsolete/end-of-life, with remaining inventory held by specialist distributors.
Where can I buy EPF6024ATC144-10N online and what is the price?
EPF6024ATC144-10N can be sourced from specialist distributors and brokers including FPGAkey, Nantian, AIChipLink, IC-Components, Kynix, and Sierra IC, since the part is obsolete and no longer in mainstream distributor stock. As of 2026-09-12, single-unit pricing on surplus channels is approximately USD 28.50, with volume breaks down to USD 14.95 at 1000 pieces. Lead times are typically 2-6 weeks depending on remaining factory or distributor stock.
What is the lead time for EPF6024ATC144-10N?
Because EPF6024ATC144-10N is end-of-life, lead times vary from immediate shipment (when in stock at a broker) to 6-12 weeks when parts must be sourced from factory wafer banks or franchise inventory. As of 2026-09-12, distributors such as FPGAkey and AIChipLink list the part on a quote basis rather than live stock. Request firm quotes from at least three brokers and confirm traceability documentation (date code, lot, country of origin) before placing production orders.
Is EPF6024ATC144-10N in stock at any major distributor?
EPF6024ATC144-10N is not in stock at major franchised distributors as of 2026-09-12; the part has been migrated to obsolete status by Altera/Intel. Specialist brokers and aftermarket distributors such as Sierra IC, Nantian, IC-Components, and AIChipLink may carry limited inventory. For new designs, consider migrating to EP4CE6 or EP4CE10 (Cyclone IV) or Lattice iCE40 parts, which are active and available.
What is the difference between EPF6024ATC144-10N and EPF6024ATC144-3N?
EPF6024ATC144-10N is a -10 speed grade (slower, 10 ns pin-to-pin delay class), while EPF6024ATC144-3N is the -3 speed grade (faster, ~3 ns). Both share the same 144-pin TQFP footprint, identical 1960 LE / 117 I/O architecture, and lead-free assembly, so they are pin-to-pin drop-in alternatives. Choose -3N when timing closure is tight; -10N is acceptable for glue-logic, slow bus bridging, and cost-sensitive legacy designs.
What is the difference between EPF6024ATC144-10N and EPF6024ATC144-1N?
EPF6024ATC144-10N (speed grade -10) is slower than EPF6024ATC144-1N (speed grade -1, ~1 ns class), but both share the same 144-pin TQFP package, identical 1960 logic elements, 117 user I/Os, and lead-free assembly. They are drop-in compatible on the same PCB footprint, so designers can migrate between speed grades without board rework. Choose -1N only when timing closure requires it; -10N is typically lower cost on the surplus market.
Can EPF6024ATC144-3N replace EPF6024ATC144-10N directly?
Yes, EPF6024ATC144-3N is a drop-in replacement for EPF6024ATC144-10N. Both parts share the same 144-pin TQFP (T144) footprint, identical 1960 logic elements, 117 user I/Os, 5.0 V core supply, and lead-free assembly. The only difference is the speed grade: -3N is faster than -10N. Because timing is the only difference, the slower part will always meet the setup/hold of a design built for the faster part.

It supports multi-voltage I/O (5.0 V / 3.3 V / 2.5 V), JTAG boundary-scan testability, and SRAM-based configuration requiring an external boot memory. The part is now obsolete and primarily available through surplus distributors; new designs should consider Cyclone IV or Lattice iCE40 equivalents.
When should I choose EPF6024ATC144-10N over a Cyclone IV FPGA?
Choose EPF6024ATC144-10N only when you must maintain exact pin compatibility with a legacy FLEX 6000 design, replicate an obsolete board for spare-part production, or study the FLEX 6000 architecture for educational or maintenance reasons. For all new designs, Altera/Intel Cyclone IV (EP4CE6, EP4CE10) or Lattice ECP5/iCE40 are far better choices: lower core voltage (1.2 V), more logic, lower power, modern toolchains (Quartus, Diamond), and active distributor stock.
Is there an Intel / Altera equivalent or replacement for EPF6024ATC144-10N?
Yes - within the Altera/Intel portfolio, the closest drop-in replacements are the other speed grades of EPF6024ATC144 (-3N, -1N), all sharing the 144-pin TQFP footprint. For a modern migration, the Altera/Intel Cyclone IV family (EP4CE6E22, EP4CE10E22 in similar packages) is functionally similar but requires PCB redesign. Cross-brand equivalents are limited; Lattice ispMACH 4000ZE and Xilinx XC9500XL series are pin-compatible architectural alternatives in CPLDs rather than true FPGAs.
What is the best cross-brand equivalent for EPF6024ATC144-10N?
The best cross-brand equivalents for the EPF6024ATC144-10N are 5 V SRAM-based FPGAs from Xilinx's XC4000E series or Lattice's ispXPGA family in 144-pin TQFP packages. These are not pin-for-pin compatible but offer similar logic capacity (around 2000 logic cells), JTAG support, and 5 V operation, making them suitable for board-level re-designs where the PCB can be re-laid. For direct drop-in, stay within the Altera FLEX 6000 family speed-grade options.
How much power does EPF6024ATC144-10N consume?
EPF6024ATC144-10N draws core current proportional to toggle rate and logic utilization; with all 1960 LEs switching at 50 MHz and 5.0 V VCCINT, ICCINT typically ranges from 50 mA to 250 mA depending on design density. Idle current is around 10-30 mA. Designers should budget approximately 1.0-1.5 W for a fully utilized commercial-temperature design and provide adequate decoupling (one 0.1 uF per VCCINT pin plus bulk capacitors) on the PCB.
What configuration memory does EPF6024ATC144-10N require?
Because FLEX 6000 is SRAM-based, the EPF6024ATC144-10N loses its configuration on power-down and must be loaded from an external boot memory at every power-up. Typical choices are a serial EPC1/EPC2 configuration EPROM (for designs up to ~2 Mbit) or a parallel x8 flash/EPROM connected to the DATA[7:0] bus. Configuration mode is selected by the MSEL[1:0] pins per the FLEX 6000 datasheet. Designers must budget PCB space for the configuration memory.

Guide de sélection

Choose the EPF6024ATC144-10N only when you need a 1960-LE 5 V FLEX 6000 FPGA for cost-sensitive legacy maintenance where 10 ns timing is acceptable and lead-free (RoHS) assembly is required. For new designs, migrate to Altera/Intel Cyclone IV EP4CE6 or EP4CE10, which are active products with modern toolchains and lower power. If you need a pin-compatible alternative in the same package, choose EPF6024ATC144-3N (faster, ~3 ns) or EPF6024ATC144-1N (fastest, ~1 ns) when timing closure is tight. Choose EPF6024ATC144-10 (no N) only if you specifically require SnPb-leaded assembly for legacy aerospace or military builds that prohibit Pb-free components. All five parts share the 144-pin TQFP footprint and 117 user I/O count, so PCB layout is fully reusable.

Principaux différenciateurs

  • Lowest-cost drop-in variant in the FLEX 6000 family (vs EPF6024ATC144-3N)
  • Lead-free assembly variant in modern RoHS-conscious builds (vs EPF6024ATC144-10)
  • Best cost-vs-speed ratio for slow glue logic (vs EPF6024ATC144-1N)

Notes de conception

The FLEX 6000 family requires a stable 5.0 V VCCINT and separately decoupled VCCIO bank supplies (5.0 V / 3.3 V / 2.5 V). Place one 0.1 uF ceramic decoupling capacitor adjacent to every VCCINT and VCCIO pin, plus a single 47-100 uF bulk capacitor per supply rail within 1-2 cm of the package. Estimated ICCINT for a typical 50% utilized design toggling at 50 MHz is 50-150 mA, so budget 0.5-1.0 W of core dissipation. Avoid tying VCCINT and VCCIO to the same rail unless your design uses 5 V I/O exclusively.

FLEX 6000 is SRAM-based, so the EPF6024ATC144-10N loses its bitstream at every power-down. You MUST include an external configuration memory (EPC1/EPC2 serial EPROM, or x8 flash/EPROM in parallel mode) selected by the MSEL[1:0] pins, otherwise the device will boot unconfigured and all I/Os will be tri-stated. Also note that the nCONFIG pin must be held low through power-up ramp and released only after VCCINT stabilizes, or configuration will fail intermittently. Always include a 10 kohm pull-up on nCONFIG and CONF_DONE.

The 144-pin TQFP has a 0.5 mm lead pitch, requiring careful PCB escape routing. Use a 4-layer stack-up with a dedicated ground plane adjacent to the FPGA layer to control impedance on high-speed I/O. Separate analog and digital ground returns if you are routing analog signals on user I/Os, and place decoupling on the opposite side of the board directly under the VCC pins. Keep JTAG chain traces (TCK, TMS, TDI, TDO) under 100 mm total length and series-terminate if longer than 50 mm.
