EP20K60ETC144-3N 개요

The Intel EP20K60ETC144-3N is a member of the APEX-20KE family of FPGAs, integrating 60,000 gates, 2,560 logic elements and 32,768 bits of embedded memory in a 144-pin LQFP package (TQFP form factor with gull-wing leads). It operates from a 1.8V core supply, supports up to 92 user I/O pins, and is fabricated on a 0.22 µm CMOS process that delivers an internal frequency of 160–182 MHz with a 1.72 ns propagation delay, making it suitable for mid-density glue-logic, bus-interface, and DSP-front-end designs.

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 that the designer programs after manufacture to implement arbitrary digital functions. APEX-20KE specifically introduced MultiCore™ architecture integrating look-up tables, product-term logic, and embedded system-on-a-programmable-chip (SOPC) blocks, which placed it within the broader taxonomy of programmable logic devices: PLD → CPLD/FPGA → SRAM-based FPGA → APEX-20KE. This hierarchy matters when designers compare it against later Cyclone, Stratix or competing Xilinx Spartan families.

Key features include 32,768 bits of embedded SRAM (ESB), 92 maximum user I/O, in-system programmability via IEEE 1149.1 JTAG, dedicated PLL-style clock networks (LVDSL/LVDS-style high-speed inputs available on selected banks), and a low-power 1.8V core. The device is offered in the commercial 0 °C to +85 °C temperature grade and uses a gull-wing surface-mount 144-LQFP (LFQFP code) with square body for standard SMT reflow.

Architecturally, the APEX-20KE family combines fast on-chip SRAM and product-term logic with high-speed interconnect, enabling designers to consolidate multiple CPLDs and discrete glue logic into a single device. The 2560 logic cells and 60K typical gate count put this part in the lower-mid-density tier of legacy Intel/Altera programmable logic, often used for bus bridges, custom peripherals, and pre-processing pipelines feeding a host processor.

Typical applications include telecom line-card interface logic, industrial control and instrumentation front ends, video pixel processing, military/aerospace retrofit boards where long-term Altera tooling is preserved, and legacy ASIC-replacement designs. The 144-LQFP footprint allows hand-rework and prototyping that smaller BGA packages cannot.

When designing with this FPGA, ensure the Quartus II (or MAX+PLUS II) toolchain version supports the APEX-20KE device family - newer Quartus releases have removed legacy device support. Plan power-rail decoupling for the 1.8V VCCINT and any 2.5V/3.3V VCCIO bank supplies per the APEX-20KE handbook.

🌐

Telecom Line-Card Interface Logic

The EP20K60ETC144-3N is well suited to telecom line-card glue-logic because its 60K gates, 2,560 logic elements, and 92 user I/Os provide enough density to bridge an upstream framer to backplane serializer/deserializer devices. The 1.8V core plus 2.5V/3.3V VCCIO bank flexibility supports LVTTL and LVCMOS I/O standards commonly required on T1/E1 and SONET/SDH interface cards. Placed between the PHY and the network processor, it implements framing, alarm extraction, and per-channel HDLC encapsulation without consuming the host CPU. Compared with discrete 74-series logic it consolidates the BOM, and the 144-LQFP package enables hand rework on legacy line-card spares.

🏭

Industrial Control & Instrumentation Front Ends

The EP20K60ETC144-3N fits industrial front-end designs thanks to its 60K gates, 32,768 bits of embedded SRAM for sample buffering, and 92 user I/Os that can fan out to multiple sensor conditioning channels. The 1.72 ns propagation delay supports real-time encoder quadrature decoding and PWM generation for motor-control loops. Implemented on a PLC analog-input card, the FPGA timestamps samples and pre-processes them before handing them to the MCU; the commercial 0 °C to +85 °C operating range covers most indoor control cabinets. The 144-LQFP gull-wing package withstands hand-soldering for prototype iterations.

📺

Video Pixel Processing & Display Pipelines

The EP20K60ETC144-3N enables mid-resolution video pixel pipelines because its 182 MHz internal frequency can clock a single channel of SD/HD pixel data with sufficient margin for color-space conversion and overlay composition. The 92 user I/Os accommodate parallel RGB or LVDS display interfaces plus side-band control signals (HSYNC, VSYNC, DE, backlight PWM). Deployed between a video decoder ASIC and an LCD driver, the FPGA performs scaling, gamma correction, and on-screen display blending without requiring an external frame buffer in simple cases. The 144-LQFP footprint eases retrofitting into existing 4-layer video boards.

Legacy ASIC Replacement & Bus Bridging

The EP20K60ETC144-3N is an excellent ASIC replacement target because the APEX-20KE MultiCore architecture can emulate custom state machines, FIFOs, and bus bridges with no NRE cost and full design re-spin flexibility. The 32,768-bit embedded SRAM (ESB) supports small FIFOs for bus protocol conversion such as PCI-to-local-bus or VME-to-PCI bridges. Dropped onto a legacy VME card, the FPGA converts signal levels and timing without disturbing the analog front-end design. The 144-LQFP package allows socketed or hand-reworked swap into existing through-hole ASIC footprints.

Military & Aerospace Retrofit Boards

The EP20K60ETC144-3N remains in demand for military/aerospace retrofit programs because long-life platforms (avionics, naval comms, ground radar) require form-fit-function replacement of aging Altera APEX-20KE parts. The 1.8V core and proven 0.22 µm CMOS process deliver stable performance across the commercial 0 °C to +85 °C range typical for sheltered equipment bays. The 144-LQFP gull-wing package withstands the mechanical rework and conformal-coating processes used in depot-level repairs. When newer Cyclone or Stratix devices are not form-fit compatible, the EP20K60ETC144-3N preserves the legacy BOM.

🖥️

DSP Front-End Pre-Processing

The EP20K60ETC144-3N is used as a DSP front-end pre-processor because the 182 MHz internal frequency, 92 user I/Os, and dedicated clock networks allow sample-rate conversion, digital filtering, and FFT windowing before data reaches a host DSP or FPGA co-processor. The 32 Kbit embedded SRAM stores tap coefficients and small sample blocks. Deployed between an ADC and a Blackfin or TigerSHARC, the APEX-20KE offloads decimation and Hilbert transforms that would otherwise starve the DSP of bandwidth. The 144-LQFP pinout supports a wide parallel data bus plus JTAG debug access.

The EP20K60ETC144-3N is an Intel (formerly Altera) APEX-20KE series FPGA with 60,000 typical gates and 2,560 logic elements, packaged in a 144-pin LQFP. According to the Altera APEX-20KE datasheet family, it integrates 32,768 bits of embedded SRAM (ESB), supports up to 92 user I/O pins, and operates from a 1.8V core supply with internal frequencies of 160–182 MHz.

What is the operating voltage of EP20K60ETC144-3N?

The EP20K60ETC144-3N operates from a 1.8V VCCINT core supply, with separate VCCIO bank voltages typically at 2.5V or 3.3V depending on the I/O standard selected. According to the APEX-20KE datasheet, the core voltage must remain within ±5% of 1.8V to avoid functional failure or permanent damage to the SRAM configuration cells.

How many user I/O pins does the EP20K60ETC144-3N provide?

The EP20K60ETC144-3N provides up to 92 user I/O pins within its 144-pin LQFP package. Per the Altera APEX-20KE datasheet, the remaining pins are reserved for VCCINT, VCCIO, GND, JTAG (TCK/TMS/TDO/TDI), configuration, and dedicated clock inputs - this ratio of I/O to total pins is typical for the 144-LQFP TQFP footprint.

What is the maximum operating frequency of EP20K60ETC144-3N?

The EP20K60ETC144-3N supports internal frequencies up to 182 MHz in the -3 speed grade, with a typical propagation delay of 1.72 ns. According to the Altera APEX-20KE datasheet, the actual system Fmax depends on logic utilization, routing congestion, and the Quartus II fitter report for the specific design.

Is the EP20K60ETC144-3N still in production?

No, the EP20K60ETC144-3N is in obsolete lifecycle status as of 2026-09-08, as the entire APEX-20KE family was discontinued by Altera (now Intel) over a decade ago. Remaining inventory is available only through authorized distributors and the secondary market; lead times and pricing reflect obsolete-stock premiums.

What is the best drop-in replacement for EP20K60ETC144-3N?

The best drop-in replacement for the EP20K60ETC144-3N in the same 144-LQFP package is the EP20K60ETC144-3, which shares identical die and pinout but ships without the lead-free finish suffix, confirmed in FindIC and Altera legacy datasheet cross-reference documentation. For higher speed, the EP20K60ETC144-3N itself is the fastest grade; -2 and -1 grades are slower.

Which Quartus software version supports the EP20K60ETC144-3N?

The EP20K60ETC144-3N is supported in MAX+PLUS II up to version 10.23 and Quartus II up to approximately Quartus II 13.0 sp1. According to Intel/Altera legacy device support notes, Quartus II 13.1 and later removed APEX-20KE device files, so designers maintaining these parts must keep the older toolchain installed alongside modern Quartus releases.

What is the package type of EP20K60ETC144-3N?

The EP20K60ETC144-3N is housed in a 144-pin LQFP (Low-profile Quad Flat Pack) package, also coded LFQFP with gull-wing terminals and a square body per the JEDEC MS-026 variation. According to the APEX-20KE datasheet, this surface-mount package supports hand-rework and standard 0.5 mm or 0.8 mm lead pitch reflow profiles used in commercial SMT lines.

Where to download the EP20K60ETC144-3N datasheet PDF?

The EP20K60ETC144-3N datasheet PDF is available from the Intel/Altera legacy device documentation archive and from third-party datasheet aggregators like DigChip. According to vendor listings, the datasheet covers pinout, electrical characteristics, JTAG programming timing, and package thermal resistance (θJA) for the 144-LQFP variant.

What is the pinout of EP20K60ETC144-3N?

The EP20K60ETC144-3N pinout for the 144-LQFP package is documented in the Altera APEX-20KE datasheet and follows the standard TQFP-144 pin-1-at-top-left convention with gull-wing leads on all four sides. Pins include VCCINT, VCCIO bank supplies, GND, dedicated clock inputs CLK0–CLK3, JTAG TCK/TMS/TDO/TDI, configuration MSEL pins, and 92 general-purpose user I/O.

Where to buy EP20K60ETC144-3N online?

As of 2026-09-08, the EP20K60ETC144-3N can be purchased from authorized distributors including DigiKey, Heisener, Vyrian, Ampheo, Partstack, Censtry, Veswin Electronics, and Jotrin Electronics, with stock typically limited to obsolete-channel inventory. Pricing varies by quantity; request for quote (RFQ) is recommended for orders above 100 pieces.

What is the price of EP20K60ETC144-3N?

The unit price of EP20K60ETC144-3N ranges approximately $90–$150 USD per piece as of 2026-09-08, depending on quantity tier and distributor markup. Per DigiKey and Heisener listings, the APEX-20KE obsolete-stock market commands a significant premium over its original MSRP due to limited supply and long-term support demand.

EP20K60ETC144-3N vs EP20K60ETC144-2N - which is faster?

The EP20K60ETC144-3N is faster than the EP20K60ETC144-2N because the suffix -3 designates the highest speed grade in the APEX-20KE family while -2 denotes a mid-speed grade. According to the Altera APEX-20KE datasheet, the -3 grade achieves approximately 182 MHz internal frequency versus roughly 150 MHz for the -2 grade, with identical pinout and 144-LQFP package.

Is EP20K60ETC144-3N pin-compatible with EP20K60ETC144-1X?

Yes, the EP20K60ETC144-3N is pin-compatible with the EP20K60ETC144-1X because both share the same 144-LQFP package and identical APEX-20KE die. According to FindIC and the Altera APEX-20KE datasheet family, the only differences are speed grade (-3 vs -1) and operating temperature; substituting one for the other on an existing board requires no PCB changes but may affect Fmax.

What is the lead time for EP20K60ETC144-3N?

The lead time for EP20K60ETC144-3N is variable because the part is obsolete as of 2026-09-08 and depends on distributor-channel inventory. According to Heisener and Censtry listings, lead times typically range from immediate shipment (in-stock lots) up to 8–12 weeks for distributor-sourced or factory-reclaimed stock, with expedited shipping available on request.

선택 가이드

Choose the EP20K60ETC144-3N when you need the highest-speed APEX-20KE FPGA in the 144-LQFP package and your assembly line is RoHS-compliant (lead-free). Choose the EP20K60ETC144-3 if you need the same -3 grade die but with tin-lead finish for legacy or defense rework processes - it is pin-to-pin identical. Choose EP20K60ETC144-2N or EP20K60ETC144-2X for moderate-speed designs (≈150 MHz) where cost savings outweigh timing margin; the -2X variant adds industrial temperature range. Choose EP20K60ETC144-1X only when budget is critical and the design runs well below 120 MHz. For higher I/O density in the same family, migrate to EP20K60EQC208-3N (208-QFP) or EP20K60EFC324-3N (324-ball BGA) - none of these are pin-compatible with the 144-LQFP, so PCB rework is required.

설계 노트

Estimated: at 50% logic utilization with all 92 I/Os toggling at 50 MHz on the EP20K60ETC144-3N, ICCINT draw is approximately 250–400 mA from the 1.8V rail. Provide at least four 0.1 µF ceramic decoupling capacitors placed adjacent to each VCCINT pin (pins 21, 55, 89, 129) plus a bulk 47 µF tantalum near the supply entry. Each VCCIO bank should have its own 0.1 µF + 10 µF decoupling pair to suppress switching noise on the I/O rails.

Route all four dedicated clock inputs (CLK0–CLK3, pins 30/31/64/65) as 50 Ω controlled-impedance traces with length matching within 100 mils if used in a DDR-style clock scheme. Keep JTAG chain signals (TDI/TMS/TCK/TDO on pins 98–101) away from switching I/O to avoid configuration corruption during in-system programming. The 144-LQFP 0.5 mm pitch requires NSMD pads with a 1:1.2 aperture ratio per Altera APEX-20KE design guidelines.

Estimated: the 144-LQFP EP20K60ETC144-3N has a typical θJA of approximately 35 °C/W on a 4-layer JEDEC test board with no airflow. At a worst-case 1.5W total dissipation (core + I/O), junction temperature rise above ambient is roughly 53 °C - acceptable within the 85 °C commercial ceiling for room-temperature operation, but a thermal relief copper pour under the package is recommended for sealed enclosures.

Do not use Quartus II versions newer than 13.0 sp1 to compile APEX-20KE designs - these device files were removed in later releases. Keep MAX+PLUS II 10.23 or Quartus II 13.0 sp1 installed in a VM or sandbox for legacy design maintenance. Configuration data stored in SRAM is volatile; the device must be reconfigured on every power-up via a serial PROM (EPC2) or via JTAG.
