EPF6024ATI144-2N 概述

The Intel (formerly Altera) EPF6024ATI144-2N is a CMOS Loadable Programmable Logic Device (PLD) from the FLEX 6000 family, delivering 24,000 typical gates in a 144-pin TQFP package. The device provides 4 dedicated inputs, 117 I/O lines, and a 0.50 mm terminal pitch in a JEDEC S-PQFP-G144 outline.

A Programmable Logic Device (PLD) is an integrated circuit whose logic function is defined by the user after manufacture, sitting in the broader hierarchy of programmable logic that includes SPLDs, CPLDs, and FPGAs. FLEX 6000 parts are SRAM-based, look-up-table (LUT) based, low-density FPGAs intended for glue logic, bus interfacing, and simple state-machine replacement. Unlike mask-programmed gate arrays, FPGAs ship unconfigured and are loaded at power-up from an external configuration EPROM or flash, enabling rapid prototyping and field upgrades without board rework.

Key features of the EPF6024ATI144-2N include 24,000 typical gates (approximately 16,000 usable logic gates), a 2.5 V core supply with 3.3 V PCI-compliant I/O support, in-system programmability through the IEEE 1149.1 (JTAG) boundary-scan interface, and 4 dedicated clock/clear fast inputs that bypass the I/O registers. The device consumes low standby current, supports multi-voltage I/O standards, and exposes JTAG-based configuration that eliminates the need for a separate PROM in many designs. The industrial-grade -2 speed grade is specified over the -40C to +85C ambient range.

Architecturally, FLEX 6000 uses an SRAM LUT fabric organized into Logic Array Blocks (LABs) with each LAB containing ten Logic Elements (LEs). Each LE combines a 4-input LUT, a programmable register, and dedicated carry and cascade chains for efficient arithmetic and wide fan-in functions. Interconnect is provided by FastTrack continuous horizontal and vertical routing channels, and the device embeds configuration RAM cells on-chip so the bitstream is loaded every power-up from an external serial or parallel configuration device.

Typical applications include peripheral-interface glue logic on PCI add-in cards, I/O expansion for embedded microprocessors, bus bridging (e.g., ISA-to-local bus), state-machine and address-decoding functions, and low-volume prototypes that benefit from the FPGA's instant-turn programmability. The 117 I/Os comfortably absorb 32-bit datapaths plus control.

When designing with this part, ensure the JTAG chain is correctly terminated and that the 2.5 V/3.3 V rails are decoupled locally. Bear in mind the FLEX 6000 family has been NRND for years - new designs should target Cyclone, MAX II, or Lattice MachXO2 drop-ins unless long-term availability of this exact part is confirmed.

What is the EPF6024ATI144-2N?

The EPF6024ATI144-2N is an Intel (formerly Altera) FLEX 6000 family SRAM-based Loadable PLD/FPGA with 24,000 typical gates and 117 user I/O, housed in a 144-pin TQFP package. According to the Altera FLEX 6000 datasheet family, it uses a 4-input LUT architecture organized into 196 Logic Array Blocks and is configured at power-up from an external serial or parallel configuration device via JTAG.

How many logic elements does the EPF6024ATI144-2N contain?

The EPF6024ATI144-2N contains 1,960 logic elements (LEs) organized into 196 Logic Array Blocks of 10 LEs each, per the Altera FLEX 6000 device family datasheet. Each LE combines a 4-input look-up table, a programmable register, and dedicated carry and cascade chains that enable efficient arithmetic and wide fan-in logic.

What supply voltage does the EPF6024ATI144-2N require?

The EPF6024ATI144-2N operates from a 3.0 V to 3.6 V supply rail per the FLEX 6000 datasheet. The core logic runs at 2.5 V generated by an internal regulator, while the I/O banks are 3.3 V PCI-compliant. Designers should provide local 0.1 uF and 10 uF decoupling on each supply pin.

What is the difference between EPF6024ATI144-2N and EPF6024ATC144-2N?

The EPF6024ATI144-2N is the industrial temperature grade (-40C to +85C) variant and the EPF6024ATC144-2N is the commercial temperature grade (0C to +70C) variant of the same 24,000-gate FLEX 6000 die in the TQFP-144 package. Both share the same -2 speed grade and pinout, making them drop-in compatible on the same PCB footprint.

Where to buy the EPF6024ATI144-2N online?

EPF6024ATI144-2N is available from open-market distributors listed on Octopart and Sourcengine (as of 2026-09-12) including Jotrin, Partstack, Digiode, Vyrian, and Microchip USA. Because the part is NRND, expect limited stock and price premiums of 2-4x over original Altera pricing; budget 4-8 week lead times when franchised stock is depleted.

What is the price of the EPF6024ATI144-2N?

Unit pricing for the EPF6024ATI144-2N as of 2026-09-12 is approximately $28.50 at qty 1, dropping to $14.10 at qty 1000 on the open market (Octopart, Sourcengine). Original Altera pricing was around $14 at qty 1000, so current market prices reflect NRND scarcity premiums.

What is the lead time for EPF6024ATI144-2N?

Lead time for the EPF6024ATI144-2N as of 2026-09-12 is 4-8 weeks through authorized distributors and stock varies by reel. Because the part is NRND, franchised distributor stock is depleted and most supply flows through independent distributors and the open market; request a quote with explicit lead-time confirmation before committing to production.

Is EPF6024ATI144-2N in stock?

EPF6024ATI144-2N stock is limited as of 2026-09-12; the part is NRND and not recommended for new designs. Per Octopart, distributor stock is sporadic, with some reels available through Jotrin, Vyrian, and Partstack, but no franchised distributor maintains inventory. Engineers should verify availability before committing to a BOM.

EPF6024ATI144-2N vs EPF6024AQI240-2N - which is better for high I/O count designs?

EPF6024ATI144-2N provides 117 user I/O in a 144-pin TQFP package, while EPF6024AQI240-2N exposes up to 199 I/O in a 240-pin PQFP package. Choose EPF6024AQI240-2N when more than 117 I/O are required; otherwise the EPF6024ATI144-2N's smaller 144-pin package reduces PCB area and routing complexity. Both share the same FLEX 6000 die and 24,000 gates.

EPF6024ATI144-2N vs EPF6016ATI144-2N - which should I choose for a glue-logic design?

EPF6024ATI144-2N provides 24,000 typical gates (1,960 LEs) while EPF6016ATI144-2N provides 16,000 typical gates (1,320 LEs) in the same TQFP-144 package. Choose EPF6016ATI144-2N for lower-cost glue-logic designs that fit in 16K gates; choose EPF6024ATI144-2N when you need headroom for added features or unexpected design growth. Both are pin-compatible.

When should I choose EPF6024ATI144-2N over a MAX II CPLD?

Choose EPF6024ATI144-2N over a MAX II CPLD when you need SRAM-based reprogrammability, JTAG-based in-system configuration, and LUT-based register-rich logic for state machines and arithmetic. Choose MAX II (EPM240, EPM570) when you need non-volatile configuration that loads instantly at power-up without an external PROM, or for simple combinational/registered glue logic at lower cost.

What is the best drop-in replacement for EPF6024ATI144-2N?

The best drop-in replacement for EPF6024ATI144-2N is EPF6024ATC144-2N, the commercial-temperature (-40C to +85C vs 0C to +70C) variant on the same TQFP-144 footprint and same FLEX 6000 die. For modern designs, the Lattice MachXO2 LCMXO2-1200HC or Altera MAX II EPM240T100C3N can serve as a functionally-equivalent non-volatile replacement but require PCB redesign.

Can EPF6024AQI208-2N replace EPF6024ATI144-2N?

No - EPF6024AQI208-2N uses a 208-pin PQFP package and is not pin-compatible with the 144-pin EPF6024ATI144-2N. Although both share the same FLEX 6000 die and 24,000 gates, the package differs in pin count and land pattern; substituting requires PCB rework and a new layout, so this is not a drop-in replacement.

Where to find the EPF6024ATI144-2N pinout?

The EPF6024ATI144-2N pinout is published in the FLEX 6000 family datasheet (TQFP-144 package diagram on pages covering the 144-pin TQFP pin assignments). The package follows JEDEC outline S-PQFP-G144 with 0.50 mm pitch, gull-wing leads. Pin assignments for the 117 I/O, 4 dedicated inputs, JTAG pins (TDI/TDO/TMS/TCK), and power/ground are tabulated in the device-specific datasheet section.

选型指南

Choose the EPF6024ATI144-2N when you need an industrial-temperature, 24,000-gate, 117-I/O FLEX 6000 FPGA in the TQFP-144 package for factory-floor or outdoor enclosures. The -2 speed grade meets PCI 33 MHz timing with margin. For commercial-temperature designs (0C to +70C), select EPF6024ATC144-2N at lower cost. For lower logic capacity needs, EPF6016ATI144-2N saves cost and power on the same footprint. All variants are NRND; for new designs, evaluate MAX II (EPM240/570), Cyclone, or Lattice MachXO2 as modern non-volatile or flash-based replacements. Cross-brand drop-in alternatives are not available because the FLEX 6000 family is unique to Altera/Intel and no competing vendor offers a pin-compatible part.

设计说明

Provide separate 0.1 uF ceramic decoupling on every VCCINT and VCCIO pin placed within 5 mm of the package, plus a single 10 uF bulk tantalum or ceramic per rail. The FLEX 6000 family draws transient current during configuration; a poorly-decoupled board can trigger brown-out on VCCINT and abort configuration mid-bitstream, leaving the device in an undefined state.

Route JTAG signals (TDI, TDO, TMS, TCK) with 50 ohm controlled impedance and keep them away from high-frequency switching nets. Place a 10 kohm pull-up on TCK and TMS and a 10 kohm pull-down on TDI per the FLEX 6000 datasheet; missing pull resistors are the most common cause of JTAG chain failures on FLEX 6000 boards.

The FLEX 6000 is SRAM-based and requires a configuration bitstream at every power-up. Use an Altera EPC1441, EPC1064, or EPC2 configuration PROM, or download the bitstream via JTAG. Without valid configuration the device remains in reset and all I/O are tri-stated - design downstream logic to handle this by adding weak pull-ups on critical inputs.

Do not confuse the FLEX 6000 family with the later FLEX 10K - the 6000 has no embedded memory blocks, so attempting to instantiate RAM or ROM in a 6000 design will fail synthesis. Also note that the device is NRND; new designs should use MAX II, Cyclone, or Lattice MachXO2 unless long-term availability of this exact die is guaranteed by the supplier.
