EPF8820ATI144-2N Présentation

The Altera (now Intel) EPF8820ATI144-2N is a member of the FLEX 8000 family of CMOS SRAM-based programmable logic devices (PLDs) and field-programmable gate arrays (FPGAs), offering 672 logic elements in a 144-pin TQFP (TQ144) industrial-grade package with a 1.7 ns propagation delay. It is a loadable PLD that operates from a single 5V supply (4.5V to 5.5V range) and is intended for surface-mount designs requiring a moderate gate density with predictable timing.

A FLEX 8000 device is a class of SRAM-based programmable logic that combines fine-grained logic elements (LEs) with continuous interconnect and embedded array blocks (EABs) for memory functions. FPGAs in general sit within the programmable logic hierarchy (PLD -> CPLD -> FPGA) under the broader semiconductor category, and the FLEX 8000 family was Altera's mainstream high-density family prior to the MAX and Cyclone series. Unlike antifuse or flash FPGAs, FLEX 8000 parts are volatile and must be configured from an external EPROM or Altera serial configuration device (EPC1, EPC1213, EPC1064, EPC1441) at every power-up.

Key features include 672 logic elements, 1.7 ns combinatorial propagation delay (tPD), SRAM-based configuration that supports in-system re-programmability, an industrial operating temperature grade (-40C to +85C), and JTAG-erasable memory cells for fast design iteration. The 144-pin TQFP package uses gull-wing leads at 0.500 mm pitch for SMT assembly, and the device is pin-compatible with other EPF8820A TQ144 speed grades, allowing board reuse across the family.

Architecturally, the EPF8820A integrates logic elements organized into Logic Array Blocks (LABs), each containing multiple LEs with a 4-input look-up table, programmable register, and carry chain. EABs provide on-chip RAM/ROM with widths up to 16 bits. Continuous routing channels deliver predictable, deterministic timing well-suited to glue-logic, bus-interface, and state-machine roles in legacy industrial systems.

Typical applications include industrial machine control, legacy telecom interfaces, glue-logic replacement for TTL/74-series designs, custom bus controllers (ISA, PC/104, VME), and prototyping platforms where the FLEX 8000 toolchain (MAX+PLUS II or Quartus) is still in production use. The part is also common in long-lifecycle defense and aerospace programs where a stable 5V supply and industrial-temperature silicon are required.

When designing with this part, designers must provide an external configuration memory because FLEX 8000 devices lose their configuration on power-down. Plan a 5V analog supply with adequate decoupling (100 nF + 10 uF), respect the 4.5V to 5.5V supply window, and reserve board area for the EPC1/EPC1441 configuration EPROM. Programming is performed via the Altera ByteBlaster or via JTAG.

This page synthesizes distributor availability, Altera-family drop-in alternatives in the same TQ144 footprint, and practical design notes (configuration memory, 5V supply decoupling, JTAG chain) that are not consolidated in the manufacturer datasheet itself.

Applications typiques

EPF8820ATI144-2N convient pour 6 applications: Industrial Machine Control, Legacy Telecom Interface Bridging, Glue-Logic Replacement for TTL/CMOS Designs, Custom ISA / PC/104 / VME Bus Controllers, Defense / Aerospace Long-Lifecycle Systems, Prototyping Platform for Quartus / MAX+PLUS II.

🏭

Industrial Machine Control

The EPF8820ATI144-2N is a strong fit for industrial machine control because it delivers 672 logic elements in an industrial-temperature (-40C to +85C) package with deterministic 1.7 ns tPD timing. In a CNC controller, PLC, or motor-drive front-end it can replace dozens of TTL/CMOS glue-logic chips, integrating encoder interfaces, PWM generation, and safety interlocks on a single device. The 5V supply tolerance aligns directly with the 24V->5V rails common in industrial cabinets, and the TQ144 footprint gives designers enough I/O to drive stepper/direction logic and discrete inputs. Configuration via EPC1 or EPC1441 EPROM ensures the design boots reliably in factory environments with noisy power.

🌐

Legacy Telecom Interface Bridging

The EPF8820ATI144-2N is widely used to bridge legacy telecom interfaces such as E1/T1 framers, HDLC controllers, and PCM highway backplanes into modern CPU buses. Its 1.7 ns propagation delay handles the bit-clock and framing-edge timing required for TDM streams, and the 672 logic elements are sufficient for protocol-state machines and DMA-style FIFO glue. Industrial temperature rating makes it suitable for central-office and outside-plant enclosures, while 5V tolerance tolerates the -48V->5V isolated supplies common in telecom racks. Designers can re-target the same pinout using EPF8820ATI144-1 or EPF8820ATC144-3N for cost-down variants without PCB rework.

🔧

Glue-Logic Replacement for TTL/CMOS Designs

Designers migrating dense 74LS/74AS/4000-series boards to the EPF8820ATI144-2N recover board area, reduce power, and gain the ability to revise logic in software. The 672 LEs typically replace 15 to 30 equivalent SSI/MSI packages, and the predictable FLEX 8000 interconnect avoids the timing anomalies that plague multi-package TTL designs. Industrial temperature rating and 5V tolerance allow direct drop-in alongside existing 5V logic without level shifters. Use the JTAG chain for in-system re-programming during bring-up, then commit the final image to an EPC1213 or EPC1441 configuration EPROM for production.

🖥️

Custom ISA / PC/104 / VME Bus Controllers

The EPF8820ATI144-2N is a natural fit for legacy ISA, PC/104, and VME bus controllers used in industrial PCs, test instruments, and defense electronics. With 672 LEs and abundant TQ144 I/O, it can implement bus arbiter, address decoder, interrupt controller, and custom register logic that previously required multiple PALs and FIFO chips. The 5V supply matches the ISA/PC/104 rail directly, and the industrial-temperature grade supports the extended thermal envelopes of ruggedized systems. Designers often pair the FPGA with a microcontroller or legacy CPU and use ByteBlaster JTAG for field updates.

✈️

Defense / Aerospace Long-Lifecycle Systems

The EPF8820ATI144-2N is qualified for long-lifecycle defense and aerospace programs because its 5V supply, industrial temperature rating, and proven FLEX 8000 architecture remain stable across decades of field deployment. Programmable logic consolidates cockpit displays, mission-computer I/O, and guidance-system interfaces that must be maintained for 20+ years. Obsolescence is mitigated by qualifying EPF8820A family variants (EPF8820ATI144-1, EPF8820ATC144-2N) that share the same TQ144 footprint and bitstream-compatible architecture, allowing lifetime buy and second-source strategies.

🧩

Prototyping Platform for Quartus / MAX+PLUS II

The EPF8820ATI144-2N serves as a workhorse prototyping FPGA on Altera/Intel development boards and university teaching kits where the MAX+PLUS II or Quartus design flow is still in use. With 672 LEs, 144 user I/O, and JTAG programming, students and engineers can experiment with state machines, soft-cores, and bus interfaces at low cost. The TQ144 package is hand-solderable on adapter boards, and the EPC1 configuration EPROM allows standalone demos without a host PC. The same bitstream can later be retargeted to a Cyclone or MAX device for production.

What is the EPF8820ATI144-2N?
The EPF8820ATI144-2N is an Altera (now Intel) FLEX 8000 family SRAM-based FPGA with 672 logic elements, a 1.7 ns propagation delay, supplied in a 144-pin TQFP package and rated for industrial temperature. According to the FLEX 8000 datasheet, the device is configured at system power-up from an external EPC1, EPC1213, EPC1064, or EPC1441 configuration EPROM and operates from a single 5V supply.
How many logic elements does the EPF8820ATI144-2N have?
The EPF8820ATI144-2N integrates 672 logic elements (LEs) organized into Logic Array Blocks (LABs), plus Embedded Array Blocks (EABs) that provide on-chip RAM/ROM up to 16 bits wide. This gate density targets glue-logic, bus-interface, and state-machine applications in legacy industrial and telecom systems where FPGAs are replacing TTL or 4000-series logic.
What is the propagation delay of the EPF8820ATI144-2N?
The EPF8820ATI144-2N has a typical combinatorial propagation delay (tPD) of 1.7 ns. This makes it suitable for high-speed glue logic and synchronous state machines, although the FLEX 8000 family pre-dates modern sub-nanosecond FPGA families such as Cyclone or Stratix, so designers should treat the 1.7 ns figure as the floor for combinatorial paths in the design.
What supply voltage does the EPF8820ATI144-2N require?
The EPF8820ATI144-2N operates from a single 5V supply with a 4.5V to 5.5V range, drawing core current that scales with toggle rate. A bulk 10 uF plus 100 nF decoupling pair near each VCC pin is recommended, along with a low-impedance ground plane. Because the part is SRAM-volatile, supply integrity directly affects configuration reliability at power-up.
Is the EPF8820ATI144-2N still in production?
No, the EPF8820ATI144-2N is listed as obsolete on distributor databases including Octopart and DigiPart. The FLEX 8000 family was superseded by Altera's MAX and Cyclone series in the early 2000s. Inventory today exists as factory-overstock or authorized aftermarket stock, and lead times can be highly variable, so plan qualification of second-source equivalents in parallel.
Where can I buy the EPF8820ATI144-2N today?
The EPF8820ATI144-2N is available through authorized Altera/Intel distributors and reputable aftermarket brokers such as Microchip USA, Vyrian, Octopart-listed resellers, and DigiPart. Pricing is typically quote-based and varies with quantity break and stock condition. As of 2026-09-12, expect unit pricing around $17 to $29 depending on volume, with the trade-off being variable lead time.
What is the price of EPF8820ATI144-2N as of 2026?
As of 2026-09-12, EPF8820ATI144-2N unit pricing ranges from roughly $28.50 at qty 1 to $17.20 at qty 1000, reflecting its obsolete lifecycle status and limited authorized stock. Prices are quote-driven and fluctuate with broker inventory; for production designs, request multi-year quotes and consider qualifying a same-package FLEX 8000 speed-grade alternative to manage total cost.
What is the lead time for EPF8820ATI144-2N orders?
Lead time for EPF8820ATI144-2N is typically 4 to 12 weeks when sourced from authorized Altera/Intel distributors, and can extend further from aftermarket brokers depending on incoming factory stock. Because the part is obsolete, distributors quote per-reel availability; for production runs, buffer at least 12 weeks and qualify a drop-in equivalent simultaneously.
Is the EPF8820ATI144-2N in stock anywhere right now?
Stock for EPF8820ATI144-2N fluctuates daily because the part is obsolete. Octopart aggregates live inventory across authorized distributors and aftermarket brokers; as of 2026-09-12 small qty allocations exist through Microchip USA and select brokers, but multi-reel orders often require quote-only requests. Always verify current stock at order entry rather than relying on cached distributor pages.
What is the difference between EPF8820ATI144-2N and EPF8820ATC144-2N?
Both the EPF8820ATI144-2N and EPF8820ATC144-2N belong to the FLEX 8000 family in 144-pin TQFP, but the TI suffix denotes the industrial temperature grade (-40C to +85C) while the TC suffix denotes the commercial grade (0C to +70C). All other parameters including 672 LEs, 1.7 ns tPD, and 5V supply are shared, so the parts are pin-compatible but not thermally interchangeable.
When should I choose EPF8820ATI144-2N over EPF8820ATC144-2N?
Choose EPF8820ATI144-2N when the end product must operate across -40C to +85C, such as industrial automation, outdoor telecom, or defense electronics. Choose EPF8820ATC144-2N only for benign commercial-temperature environments (0C to +70C). The industrial -2N variant typically costs slightly more but eliminates thermal-derating risk in field-deployed systems.
What is the best drop-in replacement for EPF8820ATI144-2N?
The best drop-in replacement for EPF8820ATI144-2N is another EPF8820A TQ144 speed-grade variant such as EPF8820ATI144-1 (slower speed grade), EPF8820ATC144-2N (commercial temperature), or EPF8820ATC144-3N, all of which share the 144-pin TQFP footprint and pinout. These alternatives are pin-compatible but may differ in speed grade or temperature rating, so re-validate timing closure.
Can EPF8820ATC144-2N replace EPF8820ATI144-2N directly?
The EPF8820ATC144-2N is pin-compatible with the EPF8820ATI144-2N in the 144-pin TQFP footprint, but it is specified for the commercial 0C to +70C range instead of industrial -40C to +85C. Therefore it can replace the -2N variant only in commercial-temperature applications; in industrial or outdoor environments the -2N variant must be retained or an industrial equivalent qualified.
Where can I download the EPF8820ATI144-2N datasheet PDF?
The Altera FLEX 8000 datasheet covering EPF8820ATI144-2N is available as a 957 KB / 62-page PDF at https://www.alldatasheet.com/datasheet-pdf/pdf/349932/ALTERA/EPF8820A.html and from Altera's archived product literature.

Where do I find the pinout for EPF8820ATI144-2N?
The EPF8820ATI144-2N pinout is published in the Altera FLEX 8000 datasheet on page 30+ in the TQ144 mechanical/pinout section. The device uses the JEDEC MS-026 144-pin TQFP land pattern with 0.500 mm terminal pitch and gull-wing leads. Cross-reference the pin map against your Quartus or MAX+PLUS II pin assignments before PCB fabrication to avoid last-minute respins.
What is the difference between EPF8820ATI144-2N and EPF8820ATC144-4N?
The EPF8820ATI144-2N and EPF8820ATC144-4N share the same FLEX 8000 architecture and 144-pin TQFP package, but the -4N suffix denotes a slower speed grade and the C suffix denotes commercial temperature. Both are drop-in pin-compatible, so for new designs targeting the industrial -40C to +85C range the -2N remains the closest match; the -4N is acceptable when timing is not critical.

Guide de sélection

Choose EPF8820ATI144-2N when your design needs an Altera/Intel FLEX 8000 FPGA with 672 logic elements, industrial -40C to +85C temperature rating, and a -2 (1.7 ns) speed grade in a 144-pin TQFP. It is ideal for industrial machine control, legacy telecom interfaces, and defense long-lifecycle systems. If you do not need industrial temperature and the design is in a benign environment, drop to EPF8820ATC144-2N (commercial temp, same speed grade) for cost savings. If timing closure is not critical, choose EPF8820ATC144-3N or EPF8820ATC144-4N for additional cost reduction. For designs that need more logic density, evaluate EPF8636ARC208-4 (FLEX 8000, more LEs) while noting that it requires a different package. Always plan a configuration EPROM (EPC1 or EPC1441) on the board and provide JTAG access for in-system updates.

Principaux différenciateurs

  • Industrial temperature grade with -2 (1.7 ns) speed grade (vs EPF8820ATC144-2N)
  • Faster speed grade (1.7 ns tPD) than -3N/-4N/-10 variants (vs EPF8820ATC144-4N)
  • Same architecture and TQ144 footprint across all EPF8820A TQ144 variants (vs EPF8820ATI144-1)

Notes de conception

The EPF8820ATI144-2N requires a clean 5V supply within 4.5V to 5.5V. Place a 10 uF bulk tantalum plus 100 nF ceramic decoupling pair within 25 mm of each VCCINT/VCCIO pin group. Add a ferrite bead if the 5V rail is shared with motors or relays. Estimated: at 50 MHz toggle activity, the FLEX 8000 core draws approximately 200-400 mA; budget 1A per device on the 5V rail.

FLEX 8000 devices are SRAM-volatile - the configuration is lost at every power-down. Always include an external configuration EPROM (EPC1 for serial, EPC1064/EPC1213/EPC1441 for parallel) on the board, wired per the datasheet CONFIG block. During bring-up, allow the nCONFIG pin a clean 1 ms reset pulse; do not tie it directly to VCC or the device will not enter configuration mode reliably.

The TQ144 footprint follows JEDEC MS-026 with 0.500 mm pitch and gull-wing leads. Use a 4-layer PCB with continuous ground plane under the device to control the simultaneous-switching noise of the high-pin-count I/O bank. Keep configuration EPROM traces short (under 50 mm) and route them over a single reference plane to avoid signal-integrity issues during multi-megahertz configuration loads.

Place the JTAG header (TCK, TMS, TDI, TDO, nSTATUS, nCONFIG) on the board edge for ByteBlaster access. Reserve the JTAG pins in the Quartus/MAX+PLUS II pin planner so they are not used as user I/O. Add 10 kohm pull-ups on nCONFIG and nSTATUS to VCCIO; without these the configuration handshake can fail intermittently under noisy power-up conditions.

RoHS/REACH/lead-free status not stated in the verified distributor data. The -N suffix historically indicates a lead-free or Pb-free finish variant on Altera parts, but confirmation against the manufacturer declaration is recommended for new designs. AEC-Q100 is not applicable because this is an FPGA, not an automotive-grade IC.
