EPF6016ATI144-2N Overview

The Intel (formerly Altera) EPF6016ATI144-2N is a FLEX 6000 family Field-Programmable Gate Array (FPGA) integrating 16,000 gates and 1,320 logic elements, fabricated on a 0.42 µm CMOS process and housed in a 144-pin TQFP package with 117 user I/O lines and 4 dedicated inputs.

A Field-Programmable Gate Array (FPGA) is a programmable logic device that combines the integration density of a gate array with the design flexibility of in-system reprogrammability. Within the broader programmable logic hierarchy, FPGAs sit alongside CPLDs as the highest-density, performance-oriented option. The FLEX 6000 family is a register-rich, LUT-based architecture that targets low-cost, high-volume gate-array replacement designs where fast prototyping iteration and fast time-to-market are priorities.

Key features of the EPF6016ATI144-2N include a maximum internal operating frequency of 166.67 MHz, an OptiFLEX®-enhanced programmable interconnect, built-in carry and cascade chains for high-speed arithmetic and wide-input functions, and embedded memory blocks distributed across Logic Array Blocks (LABs). The device supports in-system programmability via an industry-standard JTAG interface, and the 3.3 V core supply (VCCINT) with 3.0 V–3.6 V tolerance enables low-power operation compared to 5.0-V-only predecessors.

Architecturally, the device is built around LABs each containing 10 Logic Elements (LEs), interconnected through the OptiFLEX routing fabric. The LUT-based architecture delivers predictable performance independent of placement, making static timing closure easier than in cell-based ASICs. The I/O structure supports 5.0-V tolerant inputs when VCCIO is biased at 3.3 V, simplifying mixed-voltage board designs.

Typical applications include glue logic replacement, bus-bridging interfaces, peripheral controllers, industrial control logic, low-density data-path acceleration, and prototype gate-array emulation. Designers choose the EPF6016ATI144-2N when they need FLEX 6000 silicon in the legacy industrial-grade temperature window (-40 °C to +100 °C) with TQFP packaging for through-hole-friendly prototyping.

When designing with this device, ensure your Quartus II (or MAX+PLUS II legacy) toolchain supports the EPF6016 device family, as newer Intel Quartus versions have dropped older device support. Verify VCCINT and VCCIO decoupling with 0.1 µF + bulk capacitors placed adjacent to all supply pins.

Low-Density Data Path Acceleration

The EPF6016ATI144-2N accelerates simple data-path functions — CRC engines, encryption accelerators (DES, AES round logic), packet classifiers — where ASIC NRE cost is unjustified. The dedicated carry chain in every LE supports fast arithmetic at the rated 166.67 MHz, and the LAB cascade chain enables wide-input comparators for pattern matching. Designers targeting telecom or storage edge equipment commonly drop in the EPF6016ATI144-2N to offload a microcontroller's CRC, Manchester, or 8b/10b encoding tasks without migrating to a larger, more expensive Cyclone or MAX family.

Prototype Gate-Array Emulation

The EPF6016ATI144-2N is widely used as an ASIC emulator during pre-silicon validation: designers port gate-netlist logic into the LUT-based fabric and validate real-world behavior before committing to a mask set. The 144-pin TQFP package simplifies breadboard-friendly prototypes, and the -40 °C to +100 °C industrial temperature range matches the target ASIC's operating envelope, allowing thermally realistic validation. FLEX 6000 parts are particularly attractive for prototyping small-to-medium ASICs in the 5K–20K gate complexity range. Recommended companion MPNs: EPCS1 for stand-alone config storage and a JTAG header for ByteBlasterMV programming.

Legacy Industrial Control Logic

The EPF6016ATI144-2N maintains production lines running equipment built around FLEX 6000 logic, where end customers need functional replacements for field service and spare-part inventories. The TQFP-144 footprint matches existing PCBs in deployed industrial controllers, machine tools, and test rigs, so repair depots can swap a damaged FPGA without re-spinning the board. The industrial temperature grade plus 3.3 V operation make the part a long-term stable choice for installed-base support.

What is the EPF6016ATI144-2N FPGA, and what family does it belong to?
The EPF6016ATI144-2N is a Field-Programmable Gate Array (FPGA) from the Altera (now Intel) FLEX 6000 family. According to the Altera FLEX 6000 datasheet, it contains 1,320 Logic Elements (LEs) organized into Logic Array Blocks (LABs), implements approximately 16,000 typical gates, and is fabricated on a 0.42 µm CMOS process. The device is supplied in a 144-pin TQFP package and is designed for low-cost, high-volume gate-array replacement applications.
How many logic elements and user I/O pins does the EPF6016ATI144-2N have?
The EPF6016ATI144-2N provides 1,320 Logic Elements (LEs) inside 132 LABs and exposes 117 user I/O pins plus 4 dedicated inputs for a total of 121 usable pins on its 144-pin TQFP package. According to the Altera FLEX 6000 datasheet, this I/O density suits glue-logic, bus-interface, and peripheral-controller designs that need modest logic capacity with generous external pin count for parallel buses.
What is the maximum operating frequency of EPF6016ATI144-2N?
The EPF6016ATI144-2N is specified for a maximum internal operating frequency of 166.67 MHz in the -2 speed grade. According to Jotrin and FPGAkey listings derived from the Altera datasheet, this frequency is achievable for LUT-bound logic paths on the OptiFLEX interconnect. The actual achievable system clock depends on routing, fan-out, and the percentage of carry-chain logic in the user design.
What supply voltage does EPF6016ATI144-2N require, and is it 5V tolerant?
The EPF6016ATI144-2N uses a 3.3 V core supply (VCCINT) operating from 3.0 V to 3.6 V. The Altera FLEX 6000 datasheet specifies that I/O banks support VCCIO of 3.3 V with 5.0 V input tolerance, meaning the device can be safely driven from 5 V CMOS logic on its inputs when VCCIO is biased at 3.3 V. Output drive levels remain at VCCIO (3.3 V) and require a pull-up resistor to drive 5 V CMOS inputs.
What is the operating temperature range of the EPF6016ATI144-2N?
The EPF6016ATI144-2N is specified for the industrial operating temperature range of -40 °C to +100 °C. The "I" suffix in the part number (per Altera ordering nomenclature) denotes the industrial window. According to the FLEX 6000 datasheet family specification, the -2 speed grade variant supports this industrial range, making the part suitable for factory-floor, automotive-cockpit, and outdoor industrial enclosures.
Where can I buy the EPF6016ATI144-2N today, and is it in stock?
As of 2026-09-11, the EPF6016ATI144-2N is listed as obsolete / EOL by the original manufacturer Altera (now Intel). Authorized distributors no longer carry fresh inventory; remaining stock is available only from independent distributors such as Jotrin, Censtry, Microchip USA, and FPGAkey, where pricing is negotiated per quote. Lead time is typically quote-based because the device is no longer in factory production.
What is the current price of EPF6016ATI144-2N?
As of 2026-09-11, independent distributors list the EPF6016ATI144-2N at approximately USD 28.50 at qty-1 with volume discounts down to USD 17.30 at qty-1000, depending on lot date-code, traceability, and the broker's warranty terms. Because the part is obsolete, prices are highly volatile and often quoted on a per-RFQ basis rather than posted on a price sheet.
What is the lead time for EPF6016ATI144-2N orders?
Lead time for the EPF6016ATI144-2N as of 2026-09-11 is quote-based and typically ranges from 4 to 12 weeks when sourced from independent distributors. Because the part is EOL, distributors pull from allocated warehouse stock and excess OEM inventory; lead time is therefore tied to lot availability rather than factory scheduling. Designers should secure multi-year inventory during last-time-buy windows.
EPF6016ATI144-2N vs EPF6016ATC144-2N — what is the difference?
The EPF6016ATI144-2N and EPF6016ATC144-2N share the same die and TQFP-144 package; the only difference is the operating temperature grade. The "I" suffix indicates industrial temperature range (-40 °C to +100 °C), while the "C" suffix in EPF6016ATC144-2N indicates commercial temperature range (0 °C to +70 °C). Both share identical electrical and timing specifications in the same -2 speed grade, so the parts are pin-compatible drop-in substitutes when the application operates within commercial range.
What is the best drop-in replacement for the EPF6016ATI144-2N?
The best drop-in replacements for the EPF6016ATI144-2N are other FLEX 6000 family devices in the same 144-pin TQFP package and -2 speed grade, namely EPF6016ATC144-2N (commercial temperature only) and EPF6016AT144-3N (faster -3 speed grade, same TQFP-144 footprint). All three parts share identical pinout, JTAG programming interface, and Quartus II/MAX+PLUS II tool support, so they can be interchanged without PCB rework when the speed grade or temperature grade trade-off is acceptable.
Is there an Intel/Altera equivalent to EPF6016ATI144-2N in a different package?
Yes — the EPF6016AQC208-3N is a pin-compatible FLEX 6000 variant in the 208-pin PQFP package offering more user I/O (around 171 user I/O pins) but a different PCB footprint. The PQFP-208 variant is suitable only if your PCB layout already supports that package; otherwise it requires a re-spin. For true drop-in on the TQFP-144 land pattern, stay within the EPF6016ATC144 / ATI144 family members listed above.
Where can I download the EPF6016ATI144-2N datasheet PDF?
The EPF6016ATI144-2N datasheet is bundled in the FLEX 6000 Device Family datasheet, originally published by Altera Corporation as a 52-page PDF document. According to Alldatasheet records, the full document is hosted at https://www.alldatasheet.com/datasheet-pdf/pdf/538002/ALTERA/EPF6016.html. For Altera-archived copies, the FLEX 6000 datasheet is also indexed on Intel's legacy Altera documentation portal under the obsolete-product section.
Where can I find the EPF6016ATI144-2N pinout?
The 144-pin TQFP pinout for the EPF6016ATI144-2N is published in the FLEX 6000 Device Family datasheet on Alldatasheet and in the legacy Altera documentation archive. The pinout lists 117 user I/O pins organized into I/O banks (each with its own VCCIO), 4 dedicated inputs (INPUT1–INPUT4), JTAG pins (TCK, TMS, TDI, TDO), configuration pins (nCE, nCONFIG, nSTATUS, CONF_DONE), clock pins (CLK0–CLK3 or as labeled for the family), and multiple VCCINT / VCCIO / GND supply pins distributed around the package perimeter.
Is the EPF6016ATI144-2N still supported by the Intel Quartus toolchain?
No — the EPF6016ATI144-2N is no longer supported by Intel Quartus Prime. According to Altera's legacy toolchain matrix, the FLEX 6000 family was last supported by Quartus II version 13.0 sp1 and earlier. Designers must retain the legacy Quartus II 13.0 sp1 toolchain (or MAX+PLUS II) to compile, simulate, and program this device. Newer Quartus versions do not include FLEX 6000 device files.
What are the key specifications engineers should know about the EPF6016ATI144-2N?
Key specifications for the EPF6016ATI144-2N: 1,320 Logic Elements, 16K typical gates, 117 user I/O pins, 4 dedicated inputs, 3.3 V VCCINT (3.0 V – 3.6 V), 5 V tolerant inputs at 3.3 V VCCIO, 166.67 MHz maximum internal frequency, -40 °C to +100 °C industrial temperature range, 144-pin TQFP (22 mm × 22 mm, 0.500 mm pitch), JTAG programming, 0.42 µm CMOS process, and obsolete/EOL lifecycle status.

Selection Guide

Choose the EPF6016ATI144-2N when you need an Altera FLEX 6000 family FPGA in a 144-pin TQFP that operates across the industrial temperature range (-40 °C to +100 °C) and is being designed or serviced with the -2 speed grade timing profile. It is ideal for glue-logic replacement, bus-bridging, peripheral hubs, and ASIC emulation in industrial environments. For designs that do not need industrial temperature and want a slightly faster part, choose EPF6016ATC144-3N (commercial -3 speed grade) on the same TQFP-144 footprint. If your PCB already accepts PQFP-208 and you need more than 117 user I/Os, step to EPF6016AQC208-2N. For entirely new designs, consider migrating to a Cyclone IV or MAX V device, as FLEX 6000 silicon is EOL and only available through secondary distributors.

Key Differentiators

  • Industrial temperature range (-40 °C to +100 °C) (vs EPF6016ATC144-2N)
  • -2 speed grade with 166.67 MHz internal fMAX (vs EPF6016ATC144-3N)
  • 144-pin TQFP package for hand-rework friendly prototyping (vs EPF6016AQC208-2N)

Design Notes

Estimated: At VCCINT = 3.3 V and a typical 50% toggle rate across all 1,320 LEs at 100 MHz, the EPF6016ATI144-2N draws roughly 100–150 mA from VCCINT plus I/O current proportional to bank loading. Place one 0.1 µF ceramic decoupling cap adjacent to every VCCINT pin (8 pins total in TQFP-144) and one bulk 47 µF tantalum or 100 µF aluminum electrolytic on each VCCIO bank. VCCIO banks must not be left floating; tie unused banks to 3.3 V even if no I/O is used in that bank.

Keep JTAG chain traces (TCK, TMS, TDI, TDO) short and parallel; route them as a 4-wire bus with 100 Ω characteristic impedance if length exceeds 50 mm. Add a 10 kΩ pull-up on nCONFIG and a 10 kΩ pull-down on TMS per the FLEX 6000 configuration guidelines. The ByteBlasterMV header should be located at the edge of the PCB to avoid routing JTAG signals near switching power or clock nets. Use ground guard traces around high-speed clocks fed into INPUT1–INPUT4.

Because the FLEX 6000 I/Os are 5 V tolerant at 3.3 V VCCIO but only drive 3.3 V levels, a pull-up resistor (typically 1 kΩ–10 kΩ) is required when driving 5 V CMOS inputs. Source-terminate clock nets driven from INPUT1–INPUT4 (series resistor 33 Ω–68 Ω near the driver) to dampen reflections, especially on loads above 4 inches of trace. Avoid stub lengths on global clocks greater than 0.5 inches.

The FLEX 6000 family is no longer supported in Intel Quartus Prime versions later than 13.0 sp1; attempting to open a FLEX 6000 project in Quartus Prime 14+ triggers a "device not supported" error and the user is forced to either retain an older Quartus II install or port to a newer Cyclone/MAX device. Programmers using the original ByteBlasterMV must still be powered by 5 V from the host parallel port — modern PCs without parallel ports require a legacy-equivalent USB-Blaster clone.
