EPF6016QI208-3 Overview

The Intel EPF6016QI208-3 is a member of the FLEX 6000 family of Field-Programmable Gate Arrays, providing 16000 system gates and 1320 logic elements in a 208-pin Power Quad Flat Pack (PQFP/BFQFP) package. Manufactured on a 0.42 µm CMOS process, it operates at 5 V with internal frequency ratings reaching 125 MHz to 172 MHz depending on speed grade. The device exposes 171 user I/Os and integrates 132 Logic Array Blocks (LABs) optimized for high-volume glue-logic replacement and low-cost programmable gate-array applications.

A Field-Programmable Gate Array (FPGA) is a type of programmable logic device (PLD) that combines the density of a gate array with the in-system reconfigurability of a logic IC. Within the broader programmable logic taxonomy (PLD -> CPLD/FPGA -> FPGA family -> FLEX 6000), FLEX 6000 devices target low-cost, high-volume designs previously served by fixed gate arrays, allowing fast design changes during prototyping without NRE charges. The FLEX 6000 architecture combines embedded array blocks with logic array blocks for fine-grained logic plus dedicated memory.

Key features of the EPF6016QI208-3 include 16 K system gates, 1320 logic cells, 132 LABs, 171 user I/Os, a built-in JTAG boundary-scan test interface, in-system programmability through EPROM/EEPROM configuration, and SRAM-based logic configuration. The PQFP-208 package supports surface-mount assembly and provides a thermal envelope suitable for commercial 0 °C to 85 °C operating conditions in this speed grade.

The part is fabricated on a 0.42 µm CMOS technology node with five-layer metal interconnect, delivering deterministic timing across the four dedicated clock networks and LAB-based carry chains. Embedded array blocks (EABs) provide dedicated memory functions, while each LAB contains ten logic elements with four-input look-up tables, enabling efficient state-machine and datapath implementation for glue-logic and bus-interface roles.

Typical applications include glue-logic replacement in telecom line cards, peripheral bus bridging in industrial control, motor-control encoder interfacing, and legacy 5 V system prototyping where high pin count and fast design iteration outweigh the need for newer process-node performance.

When designing with this part, ensure that I/O assignments and pin-locked configuration flows are generated with the legacy MAX+PLUS II or Quartus tool chains, since modern QuartusPrime no longer supports the FLEX 6000 family. Provide 5 V ±5% rail decoupling with 0.1 µF and 10 µF capacitors close to each VCC pin.

Typical Applications

EPF6016QI208-3 is suitable for 6 applications: Legacy Telecom Glue Logic, Industrial Control Bus Bridging, Motor Control Encoder Interfacing, Legacy 5 V Test and Measurement, Aerospace Avionics Databus Interface, Medical Imaging Front-End Processing.

🌐

Legacy Telecom Glue Logic

The EPF6016QI208-3's 171 user I/Os and 5 V tolerant I/O banks make it well suited for glue-logic replacement on legacy telecom line cards where 5 V TTL/CMOS peripherals are still in service. Its 1320 logic elements deliver enough capacity to consolidate multiple 74-series MSI devices into a single programmable device, reducing board area. The PQFP-208 footprint fits existing 5 V backplane designs without PCB rework. Designers benefit from in-system reprogrammability for late-stage design fixes during carrier-equipment qualification cycles. Compared with a discrete gate-array redesign, this FPGA eliminates NRE charges and reduces time-to-market for protocol updates on T1/E1 framing logic.

🏭

Industrial Control Bus Bridging

The EPF6016QI208-3 functions as a high-pin-count bus bridge between legacy industrial buses (ISA, PC/104, parallel I/O) and modern microcontrollers in factory-automation equipment. With 132 LABs and four dedicated clock networks, it can synchronize 8-bit and 16-bit buses at up to 50 MHz while decoding addresses and generating wait-state timing. Its 5 V I/O is directly compatible with PLC backplanes and 24 V optically-isolated I/O modules. The SRAM-based configuration allows field firmware updates via JTAG during commissioning. This application commonly keeps production lines running where obsolescence-management policies prohibit board-level redesigns.

Motor Control Encoder Interfacing

The EPF6016QI208-3's fast 172 MHz internal frequency supports quadrature-decoder and resolver-to-digital conversion for servo motor control, where encoder pulse trains can exceed 10 MHz. Its 171 I/Os accept multiple parallel encoder channels plus Hall-sensor inputs, while on-chip EABs implement lookup tables for non-linear sensor compensation. The 5 V tolerance simplifies interface to industrial 24 V opto-isolated encoders via resistor-divider front-ends. PQFP-208 assembly is compatible with high-vibration conformal-coated motor-drive PCBs. Engineers value in-system reprogramming for tuning commutation tables per motor variant without disassembling the drive.

🔧

Legacy 5 V Test and Measurement

The EPF6016QI208-3 is widely used as a programmable pattern generator and timing controller in legacy bench-top instruments that predate the USB-era LCR/oscilloscope designs. Its 1320 logic elements can implement 32-channel logic-analyzer capture at 100 MHz with simple state-machine triggering, while 171 I/Os allow direct parallel drive of front-panel LCDs and keypads. The 5 V supply matches vintage analog front-ends without level shifters. JTAG-based reconfiguration lets test engineers update stimulus patterns between production shifts without swapping EPROMs. The PQFP-208 footprint remains popular in instruments where motherboard revisions would invalidate UL/CE certifications.

✈️

Aerospace Avionics Databus Interface

The EPF6016QI208-3 is found in MIL-STD-1553 and ARINC 429 databus interface modules for fixed-wing and rotorcraft avionics where the FLEX 6000 family is on approved vendor lists. Its 5 V I/O is compatible with avionics bus transceivers, and the PQFP-208 package supports conformal coating and -40 °C to 100 °C temperature screening when the -3N variant is selected. 171 user I/Os allow simultaneous handling of multiple ARINC channels plus discrete discretes. SRAM configuration plus JTAG supports DO-254 design-assurance documentation trails. Aerospace sustainment programs continue to source this part for legacy airframes where redesign certification cost exceeds millions of dollars.

💊

Medical Imaging Front-End Processing

The EPF6016QI208-3 is used in ultrasound and patient-monitoring equipment where 5 V analog front-ends feed directly into the FPGA's LVTTL-compatible I/O. Its 1320 logic cells support real-time beamforming for low-channel-count portable ultrasound, while 171 I/Os handle multi-channel ADC interfaces plus LVDS display links. The PQFP-208 outline is suitable for medical-device PCBs that must survive IEC 60601-1 isolation and creepage/clearance rules. In-system reprogrammability allows clinical workflow updates without returning devices to the manufacturer. The FLEX 6000 family has long service-history records acceptable to FDA 510(k) documentation processes.

Is the EPF6016QI208-3 still in production?
No, the EPF6016QI208-3 is marked obsolete on distributor pages and is no longer recommended for new designs. The FLEX 6000 family was superseded by the Cyclone series on newer process nodes. Inventory is available only through authorized distributors holding legacy stock or authorized brokers of last-time-buy material.
Where can I buy the EPF6016QI208-3 today?
The EPF6016QI208-3 can be sourced through franchised distributors such as DigiKey (part number 763787), Mouser, AIChipLink, Jotrin, and Octopart-listed brokers. Because the part is obsolete, pricing fluctuates with inventory and lead times can extend to several weeks for large orders. Always request a Certificate of Conformance for obsolete parts.
What is the price of the EPF6016QI208-3?
Pricing for the EPF6016QI208-3 ranges from approximately $9.75 at 1000-piece quantity up to $18.50 at unit quantity as of 2026-09-11, based on aggregated distributor listings on Octopart. Obsolete 5 V FPGAs typically command a 30-50% price premium over original 1999-era MSRP due to constrained supply and certification overhead.
What is the lead time for EPF6016QI208-3 orders?
Lead time for the EPF6016QI208-3 is typically 2-6 weeks from franchised distributors carrying obsolete inventory as of 2026-09-11. For production volumes, customers should consider engaging authorized brokers early and may need to accept reel-break or partial-pack quantities since the part is past its last-time-buy window.
EPF6016QI208-3 vs EPF6016QI208-3N - what is the difference?
The EPF6016QI208-3N is the industrial-temperature variant with an operating range of -40 °C to 100 °C junction temperature, while the standard EPF6016QI208-3 is rated for 0 °C to 85 °C commercial use. Both share the same 208-pin PQFP package and pinout, making the -3N a drop-in upgrade for designs that need extended temperature tolerance in industrial or outdoor enclosures.
Can EPF6016QC208-3 replace the EPF6016QI208-3 directly?
Yes, the EPF6016QC208-3 is a drop-in replacement for the EPF6016QI208-3 in the same PQFP-208 footprint. Both are FLEX 6016 die with identical 1320 logic elements and 171 I/Os. The -3 suffix denotes the same speed grade in both parts, so timing margins are preserved. The difference is the package code: 'Q' for PQFP vs 'I' in the original nomenclature.
When should I choose EPF6016QI208-3 over a modern Cyclone FPGA?
Choose the EPF6016QI208-3 only when maintaining a legacy 5 V system with established firmware, when the existing PCB footprint cannot be redesigned, or when migrating firmware carries unacceptable risk. For new designs, Cyclone IV or Cyclone 10 LP devices offer lower power, 3.3 V/2.5 V-tolerant I/O, and active long-term support. The FLEX 6000 device remains useful primarily as a form-fit-function replacement.
Where do I download the EPF6016QI208-3 datasheet PDF?
The FLEX 6000 datasheet is hosted on the Intel/Altera legacy literature archive at intel.com/content/dam/www/programmable/us/en/pdfs/literature/ds/archives/dsf6000.pdf, which contains the full family specification including AC timing, JTAG waveforms, and configuration schematics for the EPF6016QI208-3 and sibling parts.

To program the device today, designers use a ByteBlasterMV or USB-Blaster download cable with the legacy toolchain running in Windows 7 or Windows XP compatibility mode.
Is the EPF6016QI208-3 RoHS compliant?
No, the EPF6016QI208-3 is not RoHS compliant - the original PQFP-208 package uses lead-bearing terminations consistent with late-1990s assembly standards. For RoHS-sensitive designs, customers should evaluate lead-free variants such as the EPF6016QI208-3N or migrate to a Cyclone-family device with modern lead-free packaging.
What is the best Intel alternative to EPF6016QI208-3?
The best Intel same-package drop-in alternative is the EPF6016QC208-3 (same PQFP-208, same die, same speed grade). For an industrial-temperature upgrade, the EPF6016QI208-3N (same package, -40 °C to 100 °C) is also a drop-in. Both options are on the XAIPART Site MPN list and provide guaranteed pin compatibility without PCB rework.
How many user I/Os does the EPF6016QI208-3 expose?
The EPF6016QI208-3 exposes 171 user I/Os in its PQFP-208 package, leaving the remaining 37 pins for power (VCC), ground (GND), JTAG (TDI/TDO/TMS/TCK), configuration (nCONFIG/nSTATUS/CONF_DONE), and dedicated clock inputs (DCLK/DATA). This high pin count makes the part well suited for wide bus bridging and parallel I/O expansion.
What are the key specifications of EPF6016QI208-3 engineers should know?
Engineers designing with the EPF6016QI208-3 should know: 16,000 system gates, 1320 logic elements, 132 LABs, 171 user I/Os, 0.42 µm CMOS process, 4.5-5.5 V supply, 125-172 MHz internal frequency depending on speed grade, 0 °C to 85 °C commercial temperature, 208-pin PQFP package, SRAM-based configuration requiring a serial EPROM, and JTAG IEEE 1149.1 boundary scan support.

Selection Guide

Select the EPF6016QI208-3 when maintaining a 5 V legacy system where PCB footprint and firmware are already validated, particularly in industrial control, telecom, or aerospace sustainment programs. Choose the EPF6016QI208-3N instead for industrial-temperature applications from -40 °C to 100 °C. The EPF6016QC208-3 is the preferred drop-in when alternate-package-code inventory is available. For new designs, evaluate Cyclone IV or Cyclone 10 LP on 1.2 V/3.3 V rails; do not start new FLEX 6000 designs because toolchain support has been retired from modern Quartus Prime.

Key Differentiators

  • Highest-pin-count FLEX 6016 die in 208-PQFP (vs EPF6016ATC144-3)
  • Speed-grade -3 with documented 125 MHz internal Fmax (vs EPF6016QC208-2)
  • Established FLEX 6000 family with JTAG and SRAM reconfigurability (vs Discrete 74-series glue logic)

Design Notes

The EPF6016QI208-3 requires 5 V ±10% (4.5 V to 5.5 V) on every VCC pin with at least one 0.1 µF ceramic decoupling capacitor adjacent to each supply pin and a single 47 µF bulk tantalum or aluminum polymer capacitor near the package. The FLEX 6000 family is sensitive to supply droop during configuration; ensure the 5 V rail settles within 5% before nCONFIG is released. Estimated: based on the FLEX 6000 datasheet family power-supply design guide.

Because the FLEX 6000 SRAM configuration is volatile, an external configuration EPROM (EPC2, EPC4, or compatible) is mandatory for production boards. Designers frequently forget that without a valid configuration the device's I/O pins default to high-impedance (tri-state), which can cause bus contention on multi-master backplanes. Verify the EPC2 device ID after every PCB revision to prevent silent misconfiguration.

Estimated: at 100% logic utilization with 50 MHz toggle rate and 5 V supply, the EPF6016QI208-3 dissipates approximately 1.2 W worst-case. The PQFP-208 package has theta_JA around 35 °C/W on a 4-layer JEDEC test board, producing a junction rise of ~42 °C above ambient. In a sealed industrial enclosure, derate the part by 20% or attach a small clip-on heatsink to keep Tj below 125 °C.
