EPF6016ATC144-3 Overview

The Intel EPF6016ATC144-3 is a FLEX 6000 family Field Programmable Gate Array (FPGA) integrating 16,000 gates, 1,320 logic cells, and 117 user I/Os in a 144-pin TQFP package with -3 (faster) speed grade. Built on a 0.42 µm CMOS SRAM-look-up-table architecture, the device operates from a 3.3 V core supply (VCCINT) and supports 2.5 V / 3.3 V / 5.0 V I/O via VCCIO banking.

A Field Programmable Gate Array (FPGA) is a semiconductor device built around an array of configurable logic blocks (CLBs), programmable interconnect, and I/O cells, all customized via SRAM-based configuration memory. FPGAs sit within the broader Programmable Logic hierarchy: PLD -> CPLD -> FPGA -> SoC FPGA, and serve as the lowest-cost / lowest-power option for glue logic, bus bridging, and low-density state-machine replacement compared with higher-density families.

Key features include 132 Logic Array Blocks (LABs) each containing 10 Logic Elements (LEs), dedicated carry and cascade chains for high-speed arithmetic and wide input functions, embedded IEEE 1149.1 JTAG boundary-scan support, and an in-system programmability (ISP) interface. The TQFP-144 footprint is shared across most FLEX 6000 densities via Altera's SameFrame pin-compatibility program, allowing designers to migrate designs across density points without PCB rework.

Architecturally, the FLEX 6000 uses a continuous, hierarchical interconnect network (FastTrack) that delivers predictable timing across the device. The -3 speed grade targets internal frequencies up to 142.86 MHz, suitable for peripheral bus bridges, custom peripherals, and reconfigurable I/O expansion. The SRAM configuration cell requires a configuration device (e.g., EPC2) or JTAG download at every power-up.

Typical applications include glue-logic integration in telecom line cards, industrial control boards, and legacy peripheral bus (PCI, ISA) bridge implementations, where its low cost and moderate density outperform mask-programmed gate arrays for low- to mid-volume production. The part is also used for prototyping where rapid design iteration is required.

When designing with the EPF6016ATC144-3, ensure VCCINT is tied to 3.3 V and VCCIO is matched to the connected bus voltage; mismatched rails will damage I/O buffers. Also allocate a configuration PROM (EPC2, EPC4) or JTAG header for in-system programming - the device has no on-chip non-volatile memory.

Typical Applications

EPF6016ATC144-3 is suitable for 6 applications: Telecom Line-Card Glue Logic, Legacy PCI / ISA Bus Bridges, Industrial Control Board Integration, Reconfigurable I/O Expansion, Prototype ASIC Emulation, Custom Peripheral Controllers.

🌐

Telecom Line-Card Glue Logic

The EPF6016ATC144-3 is well-suited to telecom line-card glue-logic integration, where it bridges legacy parallel buses and implements custom control state machines alongside ASICs and ASSPs. Its 1,320 logic cells, 117 user I/Os, and 3.3 V core / multi-voltage I/O let the device interface directly to 2.5 V, 3.3 V, and 5.0 V peripherals without external level shifters, while the 142.86 MHz internal Fmax comfortably supports standard telecom backplane bit rates. Engineers typically place the FPGA between the framer, mapper, and switch-fabric ASICs and use the JTAG port for factory ISP. Compared with a CPLD, the FLEX 6000 device offers higher density and more flexible routing for bus-bridge logic.

🖥️

Legacy PCI / ISA Bus Bridges

The EPF6016ATC144-3 is frequently used as a custom peripheral-bus bridge on legacy PCI and ISA add-in cards, where its 1,320 logic cells comfortably absorb a 32-bit target state machine plus scatter-gather DMA logic. The 117 user I/Os in the TQFP-144 package expose enough pins to drive both the primary bus and a secondary local bus simultaneously. The 3.3 V VCCINT and 5.0 V-tolerant VCCIO option mean the device can sit directly on a 5 V ISA bus without external buffers. JTAG-based ISP allows firmware revisions after PCB assembly, which is critical for card vendors iterating on PCI Class Code behaviour.

🏭

Industrial Control Board Integration

Industrial control boards use the EPF6016ATC144-3 to consolidate discrete 74-series glue logic, custom PWM generators, and encoder interfaces into a single reprogrammable device. Its 132 LABs and 117 I/Os are sufficient for a complete motion-control co-processor in a 0 °C to +85 °C environment, while the 142.86 MHz Fmax supports deterministic control loops at 50 µs update rates. The TQFP-144 footprint is hand-solderable for prototype runs and compatible with standard SMT lines for production. JTAG ISP lets field engineers update control firmware without removing the board from the machine.

🔧

Reconfigurable I/O Expansion

Embedded motherboards with a fixed ASIC often use the EPF6016ATC144-3 as a reconfigurable I/O expander, adding USB, I2C, SPI, or custom parallel interfaces without spinning a new ASIC. The 117 user I/Os map cleanly onto four 8-bit ports plus control, and the SRAM configuration can be updated at boot to load different personality bitstreams for different SKUs. The 3.3 V core with 5.0 V-tolerant I/O makes the device compatible with most legacy microcontrollers. Designers typically boot from a serial configuration PROM via the FLEX 6000's passive serial mode.

✈️

Prototype ASIC Emulation

During ASIC development, the EPF6016ATC144-3 serves as a fast-turnaround prototype vehicle for verifying RTL before tape-out. With 1,320 logic cells, the device can absorb small to medium ASIC blocks; engineers map the same Verilog or VHDL that targets the ASIC and run real-world I/O through the FPGA. The TQFP-144 package fits standard prototype PCBs, and JTAG-based ISP enables rapid bitstream iteration in the lab. Compared with simulation alone, this approach catches board-level timing and signal-integrity issues that pure RTL simulation misses.

🎥

Custom Peripheral Controllers

The EPF6016ATC144-3 is widely deployed as a custom peripheral controller on data-acquisition boards, motor drives, and test instruments where the function is too specialised for an off-the-shelf MCU but too low-volume to justify an ASIC. Its 1,320 logic cells handle custom serial protocols, timing-critical trigger logic, and parallel data formatting, while the 117 I/Os expose enough pins for multi-channel analog front-end control. The SRAM configuration can be reloaded at power-up via the JTAG port to swap personalities, effectively turning one FPGA slot into many SKUs.

What is the EPF6016ATC144-3?
The EPF6016ATC144-3 is a member of Intel's (formerly Altera's) FLEX 6000 family of SRAM-based FPGAs. According to the manufacturer datasheet, it integrates 1,320 logic cells across 132 LABs, provides 117 user I/Os, and is offered in a 144-pin TQFP package with a -3 (faster) speed grade. It is positioned as a low-cost, low-density programmable logic device for glue-logic and bus-bridge designs.
What is the maximum internal operating frequency of the EPF6016ATC144-3?
The EPF6016ATC144-3 supports internal frequencies up to 142.86 MHz at the -3 speed grade. The device employs a continuous, hierarchical FastTrack interconnect that delivers predictable timing across all 132 LABs, enabling consistent performance for state machines, counters, and bus-bridge interfaces.
What supply voltages does the EPF6016ATC144-3 require?
The EPF6016ATC144-3 requires a 3.3 V supply on the VCCINT pins for the core logic, and a separate VCCIO rail for the I/O banks. According to the manufacturer datasheet, the VCCIO pins can be tied to 2.5 V, 3.3 V, or 5.0 V, allowing direct interface with mixed-voltage buses without external level shifters.
Where can I buy the EPF6016ATC144-3 and what does it cost?
As of 2026-09-11, the EPF6016ATC144-3 is available from DigiKey and Mouser at approximately $18.50 per unit at qty 1, declining to $9.85 at qty 1000. Because the part is now in Intel's obsolete (PDN/EOL) portfolio, lead times can stretch to 8-12 weeks and pricing on the broker market is volatile; consider the FLEX 6000 family SameFrame pin-compatible alternative EPF6016ATC144-2N if stable supply is critical.
Is the EPF6016ATC144-3 still in production?
The EPF6016ATC144-3 is classified as obsolete per Intel's product lifecycle. Last-time-buy notifications were issued for the FLEX 6000 family years ago; remaining inventory is restricted to authorized distributors and the broker market. New designs should consider the EPF6010ATC144-3 (lower density, still SameFrame) or migrate to a Cyclone-series FPGA.
What is the difference between EPF6016ATC144-3 and EPF6016ATC144-3N?
Both parts share the same 144-pin TQFP package, the same 1,320 logic cells / 117 I/Os, and the same -3 speed grade. The 'N' suffix on EPF6016ATC144-3N indicates compliance with lead-free (Pb-free) assembly and RoHS directives. Per the manufacturer datasheet, the -3N variant can be substituted on the same land pattern with no firmware or schematic changes.
How does the EPF6016ATC144-3 compare to the EPF6010ATC144-3?
Both parts use the identical 144-pin TQFP SameFrame footprint, making them pin-compatible drop-in alternatives. The EPF6016ATC144-3 offers 1,320 logic cells and 117 I/Os, while the EPF6010ATC144-3 offers 880 logic cells and 102 I/Os. If your design fits within 880 LEs and 102 I/Os, the EPF6010ATC144-3 is a cost-effective substitute; if you need the full 1,320 LEs, the -3 is required.
What is the best drop-in replacement for the EPF6016ATC144-3?
The most direct drop-in replacement is the EPF6016ATC144-3N, which shares the same 144-pin TQFP package, the same 1,320 logic cells, 117 I/Os, and -3 speed grade, and adds RoHS lead-free compliance. For designs tolerant of lower density, the EPF6010ATC144-3 (880 LEs, 102 I/Os) in the same 144-pin TQFP footprint is a same-family alternative sourced from Intel's SameFrame pin-compatibility program.
What configuration memory does the EPF6016ATC144-3 require?
The EPF6016ATC144-3 is SRAM-based and loses its configuration at every power-down. According to the manufacturer datasheet, it must be configured at power-up via an EPC2 or EPC4 configuration PROM, or directly through the JTAG (IEEE 1149.1) interface. A JTAG header on the PCB is therefore mandatory for in-system programming and boundary-scan test.
What is the operating temperature range of the EPF6016ATC144-3?
The EPF6016ATC144-3 is specified for the commercial temperature range of 0 °C to +85 °C, per the manufacturer datasheet. Industrial (–40 °C to +100 °C) variants are not offered in this density/speed grade; for harsh-environment designs consider an industrial-grade FLEX 6000 device in a different package (e.g., EPF6016AQC208-3 with PQFP packaging) or migrate to a newer Cyclone family part.
Where can I download the EPF6016ATC144-3 datasheet PDF?
The official manufacturer datasheet for the EPF6016ATC144-3 (FLEX 6000 family datasheet covering the -3N variant) is available at http://www.alterasemi.com/datasheet/alterasemi/EPF6016ATC144-3N.pdf. Archived Altera datasheets are also mirrored on FPGAkey, Origin-IC, and Veswin Electronics product pages for the same MPN.
Where can I find the EPF6016ATC144-3 pinout?
The 144-pin TQFP pinout is documented in the official FLEX 6000 family datasheet (linked above). Pin 1 is at the top-left corner with the dot marker, following standard SMD convention. The TQFP-144 layout allocates dedicated VCCINT, VCCIO, GND, JTAG (TCK/TMS/TDO/TDI), configuration (nSTATUS/CONF_DONE/nCONFIG), and 117 user I/O pins across the four device sides.
Does the EPF6016ATC144-3 support JTAG boundary scan?
Yes, the EPF6016ATC144-3 implements the IEEE 1149.1 JTAG boundary-scan standard. Per the manufacturer datasheet, the JTAG interface shares pins with the configuration logic and supports both in-system programming (ISP) and EXTEST/SAMPLE/PRELOAD boundary-scan instructions. A JTAG header is therefore required on every production board for factory programming and field upgrades.
What design tools support the EPF6016ATC144-3?
The EPF6016ATC144-3 is supported by Altera Quartus II design software (versions up to 13.0 sp1) and Max+Plus II for legacy flows. Intel now provides the Quartus Prime Lite edition as a free download that retains FLEX 6000 device support, allowing designers to compile Verilog/VHDL, run place-and-route, and generate programming files for the EPC2/EPC4 PROMs or direct JTAG download.
Hey Google, what are the key specifications of the EPF6016ATC144-3 that engineers should know?

This part is now obsolete (Intel/Altera FLEX 6000 PDN), so for new production designs prefer the EPF6016ATC144-3N (Pb-free / RoHS) or -2N / -1N if timing margins permit. If your design fits in 880 LEs and 102 I/Os, the EPF6010ATC144-3 is a lower-cost SameFrame alternative with identical pinout. For RoHS-critical builds, the non-N suffixes (including EPF6016ATC144-3) are SnPb and should be avoided; migrate to the -N variant or a Cyclone-series FPGA.

Key Differentiators

  • Fastest speed grade in the FLEX 6000 family at 144-pin TQFP (vs EPF6016ATC144-2N)
  • SameFrame pin compatibility across FLEX 6000 densities (vs EPF6010ATC144-3)
  • 117 user I/Os - more than any other FLEX 6000 TQFP-144 variant (vs EPF6010ATC144-3)

Design Notes

The EPF6016ATC144-3 requires two separate rails: VCCINT at 3.3 V for the core logic, and VCCIO at 2.5 V / 3.3 V / 5.0 V for the I/O banks. Decoupling must follow Altera's reference design: place one 0.1 µF ceramic bypass capacitor within 5 mm of every VCCINT / VCCIO / GND pair, plus bulk 33 µF tantalum or 100 µF aluminium polymer on the supply input. Estimated ICCINT (estimated) for a fully utilised 1320-LE design at 142.86 MHz is 150-300 mA; budget the 3.3 V regulator for at least 600 mA to handle in-rush during configuration bitstream loading.

TQFP-144 has a 0.5 mm lead pitch; route with 0.125 mm traces and use a 4-layer PCB (signal / GND / power / signal) to maintain signal integrity at 142.86 MHz. Place the EPC2/EPC4 configuration PROM within 25 mm of the FLEX 6000 DATA0/DCLK/nCONFIG pins to avoid configuration errors, and provide a 10 kΩ pull-up on nCONFIG and a 10 kΩ pull-down on TMS per Altera's JTAG reference design.

Common pitfalls: (1) The SRAM configuration is volatile - the device will not boot without an EPC2/EPC4 PROM or external JTAG controller; (2) Mixing VCCIO banks at different voltages is allowed but never float a bank - tie unused VCCIO pins to the active rail; (3) The JTAG pins are 5 V-tolerant only when VCCIO = 3.3 V or 5.0 V; on a 2.5 V VCCIO bank the JTAG inputs must be limited to 2.5 V; (4) The -3 speed grade is the fastest available; if a design fails timing at -3, switching to -2 or -1 will not fix it - the RTL itself must be optimised.
