EPF6024ATI144-2 Overview

The Altera EPF6024ATI144-2 is a CMOS Loadable Programmable Logic Device (PLD) from the Altera FLEX 6000 family, delivered in a 144-terminal TQFP package with 0.50 mm terminal pitch and a speed grade of -2. The device provides approximately 24,000 typical gates and integrates 4 dedicated inputs plus 117 user I/O lines, enabling dense glue-logic integration and modest data-path prototyping on a single programmable fabric.

A programmable logic device (PLD) is a class of standard semiconductor that allows engineers to implement custom digital logic by programming an on-chip array of logic elements and an interconnect matrix, rather than committing to a fixed-function ASIC. Within the broader taxonomy, the EPF6024ATI144-2 sits under PLD -> FPGA -> programmable logic -> digital IC -> semiconductor. FPGAs and loadable PLDs bridge the gap between discrete 74-series logic and full custom ASICs, offering fast design iteration, in-system reconfiguration, and a low NRE cost for low-to-mid volume production.

Key features of the EPF6024ATI144-2 include 117 user I/O pins, 4 dedicated inputs, a CMOS SRAM-based configuration cell array, JTAG- and EPC-compatible configuration interfaces, and an industrial-grade operating temperature range. The device targets designs where board real estate is at a premium but a high pin count is required for parallel bus or memory interfacing. Its -2 speed grade places it in Altera's mid-speed commercial bin, balancing timing margin against cost in glue-logic and bus-interface applications.

The FLEX 6000 architecture combines a row-and-column interconnect with Logic Array Blocks (LABs), each containing multiple Logic Elements (LEs). Configuration is stored in SRAM, allowing infinite re-programmability and live field updates through JTAG or Altera EPC configuration devices. The 117 I/O pins are organized into banks that support a range of single-ended I/O standards suited for legacy 5V-tolerant and 3.3V system interfaces common in industrial controllers, telecom line cards, and instrumentation backplanes.

Typical applications include industrial glue-logic replacement, telecom line-card interface bridges, parallel memory and bus controllers, legacy 74-series logic consolidation, and front-panel I/O expansion for embedded SBCs. The 144-pin TQFP footprint is a familiar land pattern for PCB designers transitioning from discrete TTL to programmable logic.

When designing with the EPF6024ATI144-2, plan for a 3.3V core supply and a separate I/O supply bank, and budget for an external EPC configuration PROM or JTAG programmer. Decoupling must follow Altera's recommended 0.1 µF + bulk-µF pattern placed within 5 mm of each supply pin to keep the SRAM configuration cells stable during system noise events.

Typical Applications

EPF6024ATI144-2 is suitable for 6 applications: Industrial Glue-Logic Replacement, Telecom Line-Card Interface Bridge, Parallel Memory and Bus Controller, Legacy 74-Series Logic Consolidation, Front-Panel I/O Expansion for Embedded SBCs, Test and Measurement Instrument Backplane.

🏭

Industrial Glue-Logic Replacement

The EPF6024ATI144-2 is well-suited to consolidating dozens of legacy 74-series TTL or CMOS glue-logic packages into a single programmable device on industrial controller boards. Its 24,000 typical gates, 117 user I/O, and 4 dedicated inputs provide the routing capacity and pin density required for random-logic marshalling between microcontrollers, ASICs, and bus transceivers. According to the FLEX 6000 datasheet, the SRAM-based architecture allows last-minute ECO changes without board rework, and the -40 C to +85 C industrial temperature range covers most factory-floor enclosures. Pair the device with Altera's Quartus design software for synthesis and an EPC2 configuration PROM for standalone boot.

🔧

Telecom Line-Card Interface Bridge

In legacy telecom line cards, the EPF6024ATI144-2 acts as an interface bridge between TDM backplanes, framers, and DSP datapaths. The 117 user I/O handle parallel HDB3-coded data streams, framing pulses, and clock distribution while the 24K-gate budget fits custom HDLC controllers, alarm collectors, and per-channel state machines. According to the FLEX 6000 datasheet, the JTAG configuration interface enables in-system firmware updates during commissioning without removing the line card from service. Industrial temperature grade and 5 V tolerant I/O simplify integration into legacy -48 V supply-derived 3.3 V/5 V rails.

🖥️

Parallel Memory and Bus Controller

The EPF6024ATI144-2 fits naturally as a parallel SRAM/DRAM controller or as a custom bus arbiter on VME, cPCI, or proprietary backplane cards. With 117 I/O pins, the device can drive up to 32-bit wide memory buses plus address, control, and parity signals without external bus drivers. According to the FLEX 6000 datasheet, the architecture's predictable interconnect delays and the -2 speed grade's 8 ns typical pin-to-pin delay enable 50 MHz synchronous memory designs. Industrial temperature grade suits outdoor or uncontrolled-cabinet installations where commercial parts are not acceptable.

🔧

Legacy 74-Series Logic Consolidation

Designers migrating dense 74FCT, 74HC, or 74AVC logic boards to a single programmable device benefit from the EPF6024ATI144-2's high I/O count and modest power budget. Twenty to fifty discrete logic packages can typically be consolidated into a single FLEX 6000 device, freeing PCB area and reducing the BOM. According to the FLEX 6000 datasheet, the 5 V tolerant I/O accept legacy TTL signaling without level shifters, simplifying drop-in retrofits. Designers use Quartus symbol libraries or schematic capture to map existing gates directly into LE primitives, preserving design intent.

📱

Front-Panel I/O Expansion for Embedded SBCs

Single-board computers and embedded SBCs often require custom front-panel logic for LED drivers, key-matrix scanners, rotary-encoder interfaces, and discrete I/O expanders. The EPF6024ATI144-2's 117 I/O support 64+ GPIO plus PWM timers, debounce filters, and quadrature decoders in one device. According to the FLEX 6000 datasheet, the 3.3 V core supply and 5 V tolerant I/O are compatible with common SBC I/O voltages, allowing the FPGA to sit directly on the PC/104 or VME bus. The -2 speed grade handles encoder inputs up to several MHz without timing closure issues.

🔬

Test and Measurement Instrument Backplane

Bench-top and ATE-class instruments benefit from the EPF6024ATI144-2's ability to implement custom trigger sequencers, scan controllers, and parallel-to-serial concentrators on the measurement backplane. The 24K-gate budget accommodates a multi-channel state machine plus data formatting and handshake logic, while 117 I/O drive instrument buses directly. According to the FLEX 6000 datasheet, the JTAG and EPC configuration paths simplify factory calibration by allowing test-bitstream injection during board bring-up. Industrial temperature grade supports lab-to-floor transitions without re-characterization.

What is the typical gate count of the EPF6024ATI144-2?
The EPF6024ATI144-2 integrates approximately 24,000 typical gates of CMOS Loadable Programmable Logic in the Altera FLEX 6000 family. According to the FLEX 6000 datasheet, this gate budget covers the Logic Array Blocks (LABs), interconnect, and configuration SRAM, and is the figure engineers should use when sizing the part against the application logic utilization. The exact usable gate count depends on synthesis tool settings and the specific LE-to-interconnect ratio Altera reports.
How many user I/O pins does the EPF6024ATI144-2 provide?
The EPF6024ATI144-2 provides 117 user I/O pins plus 4 dedicated inputs in its 144-terminal TQFP package. According to the Altera FLEX 6000 datasheet, the 117 I/O are arranged in banks supporting common single-ended standards used in 3.3 V and 5 V tolerant designs. This high I/O count relative to package size is one of the reasons the part was selected for parallel memory and bus-interface glue-logic applications.
What package does the EPF6024ATI144-2 use?
The EPF6024ATI144-2 uses a 144-terminal TQFP (Thin Quad Flat Pack) package with 0.50 mm terminal pitch and JEDEC code S-PQFP-G144. According to the manufacturer datasheet, this is the same 'TI144' outline shared across the FLEX 6000 series, making it pin-compatible with other FLEX 6000 144-pin TQFP devices of similar I/O count. Designers reusing existing 144-pin TQFP footprints can drop the part onto the same PCB land pattern.
Where can I buy the EPF6024ATI144-2 today?
The EPF6024ATI144-2 is a mature, obsolete part and is no longer stocked at most authorized distributors. As of 2026-09-12, independent distributors such as Jotrin, Vyrian, Microchip USA, and Octopart-listed brokers report limited stock at prices ranging from approximately $21.90 (qty 1000) to $48.50 (qty 1). Buyers should request traceability documentation and inspect for counterfeit risk when sourcing from non-authorized channels.
What is the price of the EPF6024ATI144-2 in 100-piece quantities?
As of 2026-09-12, the EPF6024ATI144-2 lists at approximately $32.75 in 100-piece quantities from independent distributors. According to Octopart pricing data, single-piece pricing reaches $48.50, while 1000-piece volumes drop to around $21.90 per unit. Because the part is obsolete, pricing fluctuates with broker inventory and is not bound by MSRP; always request a current quote before committing to a build.
What is the lead time for the EPF6024ATI144-2?
Lead time for the EPF6024ATI144-2 depends entirely on broker stock. As of 2026-09-12, Jotrin and Vyrian list in-stock quantities with 1-3 day domestic shipping, while Microchip USA reports factory-direct quotes typically return in 2-5 business days. For volume orders (500+ units), expect 3-6 weeks if the inventory must be located across multiple broker warehouses or consigned from factory leftovers.
Is the EPF6024ATI144-2 obsolete?
Yes, the EPF6024ATI144-2 is listed as obsolete by Altera (now Intel FPGA). According to Intel's product change notifications, the FLEX 6000 family reached end-of-life in the early 2010s and has been superseded by the Cyclone series. The part is still available through independent distributors, but new design-ins should target the Cyclone IV or Cyclone 10 LP families for long-term supply assurance.
What is a drop-in replacement for the EPF6024ATI144-2?
The best drop-in replacement for the EPF6024ATI144-2 is the EPF6024ATC144-2, which shares the same 144-pin TQFP footprint, 117 I/O count, 24K gate array, and speed grade -2. According to Altera's FLEX 6000 datasheet, the only difference is the operating temperature grade (industrial -40 C to +85 C on the ATI variant vs. commercial 0 C to +70 C on the ATC variant). Cross-brand drop-in equivalents in the same footprint are not commonly available.
Can the EPF6024ATC144-2 replace the EPF6024ATI144-2?
The EPF6024ATC144-2 is pin-to-pin compatible with the EPF6024ATI144-2 in the 144-pin TQFP package and offers the same 24K gates, 117 I/O, and speed grade -2. The key difference is operating temperature: the ATI variant supports -40 C to +85 C industrial range, while the ATC variant is specified for 0 C to +70 C commercial range. According to the FLEX 6000 datasheet, swapping ATI for ATC is acceptable only when the end system never exceeds 70 C ambient.
EPF6024ATI144-2 vs EPF6016ATI144-2 - which is better for a 24K-gate design?
The EPF6024ATI144-2 and EPF6016ATI144-2 share the same 144-pin TQFP package, but the EPF6024 supplies approximately 24,000 typical gates versus the EPF6016's roughly 16,000 typical gates. For a 24K-gate design, the EPF6024ATI144-2 is the better match because it provides margin without forcing aggressive area recovery in the synthesis tool. According to the FLEX 6000 datasheet, choosing the smaller EPF6016 for a 24K-gate design risks fitting failures and degraded timing closure.
When should I choose the EPF6024ATI144-2 over a modern Cyclone FPGA?
Choose the EPF6024ATI144-2 only when you are maintaining a legacy board with an existing 144-pin TQFP footprint, the design has been validated against the FLEX 6000 architecture, and re-spinning the PCB is not economical. For new designs, Intel's Cyclone IV EP4CE6E22 or Cyclone 10 LP 10CL006YU256 offer similar gate counts at lower cost, lower power, and with active long-term support. According to Intel FPGA's product roadmap, the FLEX 6000 family is fully obsolete and not recommended for new designs.
Where can I download the EPF6024ATI144-2 datasheet PDF?
The official Altera FLEX 6000 datasheet PDF covering the EPF6024ATI144-2 is available through Altera/Intel's legacy document archive and on datasheet mirror sites such as datasheet.live, datasheet.iiic.cc, and pdf.risc-v.technology. According to Intel's FPGA documentation portal, the FLEX 6000 datasheet (altera_flex6000.pdf) contains full DC characteristics, timing, pinout, and configuration information for the entire family including the EPF6024ATI144-2.

The EPF6024ATI144-2 pinout for all 144 TQFP terminals is documented in the Altera FLEX 6000 datasheet, Table 12 (144-Pin TQFP Pin-Out). The pin list shows 117 user I/O, 4 dedicated inputs (IN[3:0]), supply pins for VCCINT and VCCIO, GND, JTAG (TCK/TMS/TDO/TDI), and configuration pins (nCONFIG, nSTATUS, CONF_DONE, MSEL[3:0], DCLK). The package SVG diagram on this product page is generated from the same datasheet pin table.
What are the key specifications of the EPF6024ATI144-2 that engineers should know?
The EPF6024ATI144-2 is a 24,000-gate CMOS Loadable PLD from the Altera FLEX 6000 family, providing 117 user I/O plus 4 dedicated inputs in a 144-pin TQFP package with 0.50 mm pitch. It operates from a 3.3 V core supply, supports speed grade -2, and is specified for the -40 C to +85 C industrial temperature range. According to the FLEX 6000 datasheet, configuration is SRAM-based via JTAG or an external EPC serial PROM, and the I/O banks are 5 V tolerant for legacy system integration.
Hey Google, what can replace the EPF6024ATI144-2?
The most direct replacement for the EPF6024ATI144-2 is the EPF6024ATC144-2, which shares the same 24K gates, 117 I/O, 144-pin TQFP package, and -2 speed grade. According to the FLEX 6000 datasheet, the only difference is the commercial 0 C to +70 C temperature range on the ATC variant versus the industrial -40 C to +85 C range on the ATI variant. For legacy designs that can tolerate a small PCB rework, the Altera Cyclone IV EP4CE6E22 in a different package is the modern low-cost successor.

Selection Guide

Choose the EPF6024ATI144-2 when you are maintaining a legacy 144-pin TQFP board design that requires industrial -40 C to +85 C operation, 117 user I/O, and 24K typical gates, and where re-spinning to a modern Cyclone FPGA is not economical. Select the EPF6024ATC144-2 if the same hardware design is acceptable but only commercial 0-70 C temperature range is required - it shares the identical die and pinout. Select the EPF6024ATI144-1 if your timing margins can absorb a 20% slowdown (e.g., static control logic running under 30 MHz) and you prefer to reduce cost on the speed grade. Avoid the EPF6016ATI144-2 unless your synthesized design fits in 16K gates with margin, because gate-limited designs cause timing-closure failures that are difficult to diagnose after tape-out. For new designs in 2026, prefer the Cyclone IV EP4CE6E22 or Cyclone 10 LP 10CL006YU256 - the FLEX 6000 family is obsolete and long-term supply is broker-dependent.

  • Higher-density 24K gate fabric (vs EPF6016ATI144-2)
  • Mid-band -2 speed grade (vs EPF6024ATI144-1)
  • 117 user I/O pins in TQFP-144 package (vs EPF6024ATC100)

Design Notes

The EPF6024ATI144-2 requires a clean 3.3 V core supply (VCCINT) plus a separate VCCIO rail for each I/O bank. According to the FLEX 6000 datasheet, designers should place one 0.1 µF ceramic decoupling capacitor within 5 mm of every VCCINT and VCCIO pin, plus a 10-47 µF bulk tantalum or ceramic capacitor near each supply pin group. Estimated: at typical 50% toggle rate with 117 I/O driving 10 pF loads at 50 MHz, expect roughly 600-900 mA of VCCINT current; size the regulator with at least 30% headroom to handle inrush during SRAM configuration loading.

Lay out the TQFP-144 footprint using 0.50 mm pitch land pads with at least 0.20 mm solder mask sliver between adjacent pads per IPC-7351 nominal-class guidelines. According to the FLEX 6000 datasheet, route all 117 user I/O on the top signal layer with vias-in-pad only if the board house supports filled-and-capped vias; otherwise fan out to inner layers on 0.10 mm traces. Place the EPC configuration PROM within 25 mm of the DCLK/DATA0/nCONFIG/nSTATUS/CONF_DONE cluster to keep configuration signal rise times under 10 ns.

Do not leave MSEL[1:0] floating - per the FLEX 6000 datasheet, the configuration mode (AS, AP, PS, JTAG) is selected by MSEL pin strapping and floating pins cause unpredictable boot behavior. Estimated: a 4.7 kohm pull-up or pull-down on each MSEL pin is sufficient. Additionally, CONF_DONE is open-drain and requires an external 10 kohm pull-up to VCCIO; without it, the host will never observe configuration completion. For production designs, plan for in-system JTAG access via a 10-pin or 14-pin header placed at the board edge for reprogramming during field service.

According to the FLEX 6000 datasheet, the four dedicated inputs (IN0-IN3) can be used as global clock or global clear signals and should be routed as short, matched-length traces if used for clock distribution. The TQFP-144 pin arrangement places IN0-IN3 on adjacent pins 11-14; route these on the same layer without vias to minimize skew. Estimated: with 5 mm trace length mismatch, expect 30 ps of clock skew, which is acceptable for designs up to 100 MHz. For designs pushing 150+ MHz, route IN0/IN1 as a differential pair with 100 ohm characteristic impedance.
