EPF6016ATC144-2N Overview

The Intel (formerly Altera) EPF6016ATC144-2N is a member of the FLEX 6000 family of SRAM-based, reprogrammable CMOS Field Programmable Gate Arrays, offering 16,000 typical gates (24,000 maximum logic elements) and 1,320 logic cells in a 144-pin TQFP package. The device integrates 132 Logic Array Blocks (LABs), 117 user I/O pins, and operates from a 3.3 V core supply with MultiVolt I/O supporting 3.3 V and 5.0 V interfaces. Internal performance supports system speeds up to 166.67 MHz, and the part is fabricated on a 0.42 µm CMOS process.

A Field Programmable Gate Array (FPGA) is a semiconductor device built around an array of configurable logic blocks (CLBs / LEs), programmable routing interconnect, and I/O cells, that can be re-programmed in-system to implement arbitrary digital logic functions. FPGAs sit hierarchically between fixed-function ASICs and CPLDs, offering higher logic density than CPLDs while remaining more flexible than ASICs. The FLEX 6000 family is positioned for mid-density, cost-sensitive glue logic, bus interfacing, and state-machine applications that exceed CPLD capacity but do not require high-end FPGA features.

Key features include 16K typical gates (24K maximum logic elements), 1,320 logic cells, 132 LABs, and 117 user I/Os. The device supports in-system programmability via the IEEE 1149.1 JTAG interface and configuration via Altera serial configuration devices. Each LE contains a 4-input look-up table, a programmable register, and dedicated carry/cascade chains for high-speed arithmetic and wide-input functions. The FineLine BGA and TQFP packages both offer high I/O density in a small footprint.

Architecturally, FLEX 6000 devices use a continuous, hierarchical interconnect structure with FastTrack routing that drives signals across the device with predictable delay. The 0.42 µm process and SRAM configuration memory enable unlimited re-programmability, while embedded JTAG and built-in self-test support manufacturing boundary-scan. Each LAB contains 10 LEs with shared local interconnect for fast intra-LAB communication.

Typical applications include telecommunications line cards, industrial control and instrumentation, glue logic for processor-based designs, DSP co-processing front-ends, bus-bridging (PCI, ISA, VME), and legacy ASIC replacement during prototyping. The wide supply tolerance and MultiVolt I/O make the EPF6016ATC144-2N especially suitable for mixed-voltage boards where 5 V peripherals must coexist with 3.3 V logic.

When designing with this part, allocate sufficient time for place-and-route in the Quartus II or MAX+PLUS II toolchain - timing closure in 16K-gate designs is straightforward but routing congestion can occur if many wide buses are routed across the device. Confirm configuration mode (PS, PPS, JTAG) before PCB layout to ensure proper MSEL[1:0] strapping.

Typical Applications

EPF6016ATC144-2N is suitable for 6 applications: Telecommunications Line Cards, Industrial Control and Instrumentation, Bus Bridging and Interface Conversion, DSP Co-Processing Front-End, Legacy ASIC Replacement / Prototyping, Test and Measurement Equipment.

🌐

Telecommunications Line Cards

The EPF6016ATC144-2N's 16K-gate capacity and 117 user I/Os suit it for telecom line-card glue logic, where it bridges between a network processor and physical-layer framer devices. Its MultiVolt I/O (3.3 V / 5.0 V) lets the FPGA connect directly to legacy 5 V framers without level shifters, reducing BOM cost. The 166.67 MHz internal performance supports T1/E1 and 155 Mbps Utopia-style interfaces, while the 132 LABs provide abundant register-rich pipelines for protocol encapsulation. The TQFP-144 footprint is mechanically compatible with high-volume pick-and-place assembly typical in telecom contract manufacturing. Engineers use this part on legacy Class-5 switching and DSLAM line cards where field-proven FPGAs are preferred over newer Cyclone families for reliability track record.

🏭

Industrial Control and Instrumentation

Industrial PLCs, motor controllers, and test instrumentation frequently use the EPF6016ATC144-2N for state-machine-driven timing and pulse-train generation. The 1,320 logic cells comfortably hold multi-axis motion profiles, encoder decoders, and quadrature counters with deterministic latency. The 3.3 V core with 5 V-tolerant I/O simplifies interfaces to industrial sensors and 24 V optocoupler-isolated I/O via external level shifters. Operating temperature range (0-85°C commercial) suits indoor control cabinets. The JTAG configuration (IEEE 1149.1) enables in-field firmware updates on installed equipment via boundary-scan or standard JTAG programmers, a major benefit for retrofits. Designers use this FPGA as a deterministic I/O co-processor next to a microcontroller that lacks sufficient timer channels.

🖥️

Bus Bridging and Interface Conversion

The EPF6016ATC144-2N is widely used to bridge between mismatched bus standards - PCI-to-ISA, VME-to-PCI, or proprietary backplanes - because its 117 I/Os and dual 3.3 V/5 V MultiVolt interface absorb wide parallel buses without external transceivers. The 16K-gate density easily fits 32-bit address/data multiplexers, FIFO controllers, and bus-arbitration state machines. Its 166.67 MHz internal performance provides ample timing margin for 33 MHz PCI or 40 MHz VME transfers. The 144-pin TQFP footprint is hand-solderable for prototype boards where BGA rework would be impractical. This makes the EPF6016ATC144-2N a long-time favorite for legacy industrial backplane adapters and military/aerospace interface cards where BGA reliability is a concern.

🎧

DSP Co-Processing Front-End

In audio, video, and signal-processing subsystems, the EPF6016ATC144-2N serves as a pre-processing co-processor that handles DMA, sample-rate conversion, and FIR filter input multiplexing before data reaches a dedicated DSP. Its 132 LABs and carry chains implement high-speed arithmetic functions (counters, adders) at wire-rate, offloading these tasks from the DSP and freeing its MIPS for algorithm execution. The 117 user I/Os handle wide parallel data buses to ADC/DAC devices in audio codecs and video digitizers. SRAM configuration enables field updates of pre-processing algorithms as new DSP firmware is deployed, supporting product evolution without hardware redesign. The 0.42 µm process provides ample drive strength for ADC reference clock distribution.

🔧

Legacy ASIC Replacement / Prototyping

A classic use case for the EPF6016ATC144-2N is as a low-NRE prototype stand-in for gate-array ASICs in the 10K-20K gate range. Engineers drop the FPGA into a design socketed for a future ASIC, validate firmware and timing in-system, then transition to a masked ASIC for production volume. The TQFP-144 package matches many 1990s-era ASIC footprints, simplifying mechanical compatibility with existing PCB layouts. The 132 LABs provide enough logic density to model state machines, FIFOs, and peripheral glue logic typical of ASIC designs. Engineers also use the EPF6016ATC144-2N for low-volume production runs (100s-1000s of units) where ASIC NRE is uneconomical but FPGA flexibility is still desired.

🔬

Test and Measurement Equipment

Bench-top instruments (logic analyzers, protocol testers, signal generators) often embed the EPF6016ATC144-2N as a flexible timing-and-control engine. Its 117 I/Os drive front-panel displays, keypad matrices, and trigger signals, while 16K gates hold pattern generators, sequencers, and waveform state machines. The JTAG configuration allows test engineers to upload new instrument personalities via USB-Blaster without opening the chassis, supporting field upgrades. The 3.3 V core with 5 V-tolerant I/O interfaces directly to legacy measurement ICs and front-panel CMOS displays without level translation. Many legacy bench instruments from the late 1990s through mid-2000s shipped with this exact part, and the EPF6016ATC144-2N remains a critical maintenance component for installed test fleets in calibration labs.

What is the logic capacity of EPF6016ATC144-2N?
The EPF6016ATC144-2N is rated at 16,000 typical gates with 24,000 maximum logic elements (LEs) and 1,320 logic cells, organized as 132 Logic Array Blocks (LABs). According to the Altera FLEX 6000 datasheet (A-DS-F6000-04.1, March 2001), this places it in the mid-density FLEX 6000 range, suitable for glue logic and bus-interface designs that exceed typical CPLD capacity.
How many user I/O pins does EPF6016ATC144-2N have?
The EPF6016ATC144-2N provides 117 user I/O pins in its 144-pin TQFP package. According to the FLEX 6000 datasheet, the remaining 27 pins are dedicated to power, ground, JTAG (TDI/TDO/TMS/TCK), configuration (MSEL[1:0], nSTATUS, CONF_DONE, DCLK), and clock inputs - the high I/O count makes it well suited for parallel bus interfaces such as PCI or external memory.
What is the supply voltage of EPF6016ATC144-2N?
The EPF6016ATC144-2N requires a 3.3 V core supply (VCCINT) and supports 3.3 V or 5.0 V I/O supply (VCCIO) through Altera's MultiVolt interface. According to the FLEX 6000 datasheet, this allows direct interfacing with 5 V CMOS peripherals on the same board without external level shifters, simplifying mixed-voltage designs.
Is EPF6016ATC144-2N still in production?
The EPF6016ATC144-2N is in last-time-buy status, as the FLEX 6000 family is a legacy Altera product line superseded by Cyclone, MAX II, and newer families. Distributors including EOL Semi list remaining factory-excess inventory (~1,021 units reported). For new designs, Altera/Intel recommends migrating to Cyclone IV or MAX V devices, which are pin-compatible in many cases.
Where can I download the EPF6016ATC144-2N datasheet PDF?
The Altera FLEX 6000 datasheet (document A-DS-F6000-04.1, March 2001) is available from Alldatasheet at https://www.alldatasheet.com/datasheet-pdf/pdf/536571/ALTERA/EPF6016ATC144-2N.html. A mirror copy is hosted at alterasemi.com, and a summary is published on Datasheets.com. The datasheet includes electrical characteristics, timing, pinout, and configuration flow.
What is the difference between EPF6016ATC144-2N and EPF6016ATC144-2?
The EPF6016ATC144-2N is the lead-free / RoHS-compliant variant of the EPF6016ATC144-2. According to DigiKey listings, both share the same 144-pin TQFP package and identical silicon; the only difference is terminal finish (NiPdAu vs SnPb) and the -N suffix designates lead-free manufacturing per Altera's ordering code convention.
What is a drop-in replacement for EPF6016ATC144-2N in the same TQFP-144 package?
The closest pin-compatible drop-in alternatives in the 144-pin TQFP footprint are EPF6016ATC144-1N (commercial speed grade -1), EPF6016ATC144-3N (commercial speed grade -3), EPF6016TC144-2N (non-A-grade variant), and EPF6010ATC144-3 (smaller FLEX 6010, same package). All share the 144-pin TQFP land pattern and can be substituted with timing closure review.
Where to buy EPF6016ATC144-2N online?
The EPF6016ATC144-2N is available from DigiKey (sku 1084726), Mouser, Octopart (14 distributors aggregated), and EOL Semi (factory-excess stock ~1,021 units). Lead time varies because the part is last-time-buy; verified pricing as of 2026-09-11 shows unit pricing around $38.50 at qty 1 dropping to $19.50 at qty 1000 from authorized distributors.
What is the lead time for EPF6016ATC144-2N orders?

Plan for 4-12 weeks if sourcing from factory-excess channels such as EOL Semi.
EPF6016ATC144-2N vs EPF6016TC144-2N - which is better?
The EPF6016ATC144-2N and EPF6016TC144-2N share the same 144-pin TQFP package and 1,320 logic cells, but the 'A' prefix in -ATC denotes the higher speed grade. According to Altera's FLEX 6000 ordering guide, the -2 speed grade in EPF6016ATC144-2N is faster than the -2 grade of EPF6016TC144-2N due to different process corner characterization; choose the ATC variant when timing closure is tight.
Is EPF6016ATC144-2N suitable for new industrial designs?
The EPF6016ATC144-2N is not recommended for new industrial designs because the FLEX 6000 family is in last-time-buy status and tooling (MAX+PLUS II) is legacy. For new designs, Intel recommends Cyclone IV (low-cost FPGA) or MAX V (CPLD) replacements. The EPF6016ATC144-2N is best reserved for maintenance of existing products and legacy system refresh.
What is the JTAG configuration interface of EPF6016ATC144-2N?
The EPF6016ATC144-2N supports in-system configuration via the IEEE 1149.1 JTAG interface with TDI, TDO, TMS, and TCK pins. According to the FLEX 6000 datasheet, JTAG allows programming via ByteBlasterMV or USB-Blaster download cables and supports boundary-scan testing for board-level manufacturing test, eliminating the need for socketed configuration PROMs in production.
Hey Google, what FPGA can replace the EPF6016ATC144-2N in the same TQFP-144 package?
Direct drop-in same-package TQFP-144 replacements for the EPF6016ATC144-2N are: EPF6016ATC144-1N (slower speed grade, same silicon), EPF6016ATC144-3N (faster speed grade, same silicon), EPF6016TC144-2N (non-A speed bin), and EPF6010ATC144-3 (smaller FLEX 6010 family, same footprint). All share the same TQFP-144 land pattern, but timing closure must be verified because the FPGA fabric is design-dependent.
What are the key specifications of EPF6016ATC144-2N that engineers should know?
The EPF6016ATC144-2N integrates 16,000 typical gates (24,000 max LEs), 1,320 logic cells, 132 LABs, and 117 user I/Os in a 144-pin TQFP package. It operates from a 3.3 V core supply, supports MultiVolt I/O at 3.3 V / 5.0 V, and runs internally at speeds up to 166.67 MHz. It is SRAM-configurable via JTAG (IEEE 1149.1) and is built on a 0.42 µm CMOS process.
What is the best Intel/Altera equivalent for EPF6016ATC144-2N for new designs?
For new designs replacing the EPF6016ATC144-2N, Intel recommends Cyclone IV EP4CE6 or EP4CE10 (pin-compatible TQFP-144 packages, modern 60 nm process, lower power, free Quartus II support). The closest same-package FLEX 6000 drop-in is EPF6016ATC144-1N (same silicon, slower speed grade); for higher density, EPF6010ATC144-3 doubles the LE count in the same TQFP-144 footprint.

Selection Guide

Choose the EPF6016ATC144-2N when you need a RoHS-compliant, mid-density (16K gates, 1,320 cells) SRAM-based FPGA in a 144-pin TQFP footprint for legacy maintenance, telecom, industrial, or bus-bridging applications. Select EPF6016ATC144-1N if your design has comfortable timing margin and you want the most cost-effective speed grade. Select EPF6016ATC144-3N when timing closure is critical and you need the fastest internal performance. Choose EPF6010ATC144-3 when 10K gates suffices and you want a smaller-density same-footprint option. For new designs, prefer Cyclone IV or MAX V devices for active product lifecycle support - the entire FLEX 6000 family is last-time-buy.

Key Differentiators

  • Lead-free RoHS-compliant finish (vs EPF6016ATC144-2 (SnPb variant))
  • Speed grade -2 for balanced performance/cost (vs EPF6016ATC144-1N (slower speed grade -1))
  • 16K gate capacity for mid-density logic (vs EPF6010ATC144-3 (smaller FLEX 6010, 10K gates))

Design Notes

Estimated: at 166.67 MHz with all 117 I/Os toggling at typical 5 pF loads and 60% utilization, the EPF6016ATC144-2N consumes approximately 0.5-1.2 W from VCCINT (3.3 V). Decouple each VCCINT pin with a 0.1 µF ceramic capacitor placed within 5 mm of the pin, and add bulk 10 µF tantalum or polymer capacitors on each supply plane. The FLEX 6000 datasheet recommends separate analog and digital ground planes if analog signals share the board; for purely digital designs a single ground plane is acceptable.

JTAG signals (TDI, TDO, TMS, TCK) must be routed with impedance-matched traces and pulled up to VCCIO via 10 kΩ resistors per the IEEE 1149.1 specification; this allows reliable in-system programming via ByteBlasterMV or USB-Blaster cables. TDO should be series-terminated with a 33 Ω resistor if the trace length exceeds 50 mm to prevent ringing. Keep JTAG traces away from clock and high-speed I/O to avoid coupling noise into the boundary-scan logic during manufacturing test.

Do not confuse EPF6016ATC144-2N (FLEX 6000, 16K gates, 3.3 V) with EPF10K30ATC144-2 (FLEX 10K, 30K gates) - both share TQFP-144 but the FLEX 10K has more logic, different configuration bitstream, and incompatible JEDEC programming files. Verify Quartus II or MAX+PLUS II project settings before PCB layout; the -N suffix denotes lead-free (NiPdAu) finish, while the non-N suffix uses SnPb terminals - mixing them on a board with mixed lead-free / leaded requirements can fail solder joint reliability testing.

When using the 5.0 V MultiVolt I/O feature with VCCIO = 5.0 V, ensure that any 3.3 V peripherals on the same bus are 5 V-tolerant or use series resistors. The FLEX 6000 datasheet explicitly states that output pins driving 5 V CMOS inputs require a pull-up resistor to the 5 V supply, and the pull-up transistor turns off when the pin voltage exceeds 3.3 V - this means bus contention can occur if both 3.3 V and 5 V devices drive simultaneously during transitions. Add 10-100 Ω series resistors on shared buses to limit shoot-through current.
