EPF10K50ETC144-3 概覽

The Intel (formerly Altera) EPF10K50ETC144-3 is a member of the FLEX 10KE family of embedded programmable logic devices (PLDs), providing System-on-a-Programmable-Chip (SOPC) integration with 50,000 typical gates, 2,880 logic cells, 40,960 bits of embedded memory, and 360 LABs/CLBs in a 144-pin TQFP (also referenced as TQFP-144) surface-mount package.

A Field-Programmable Gate Array (FPGA) is a reconfigurable integrated circuit whose logic fabric, interconnect, and I/O cells are defined by a user-supplied bitstream after manufacture. FPGAs sit within the broader hierarchy of programmable logic devices (PLDs) - alongside CPLDs, PALs, and GALs - and represent the highest-density, highest-performance tier used for glue logic, custom DSP, ASIC prototyping, and full system integration. The FLEX 10KE family pioneered embedded-array architecture, combining look-up-table based logic with embedded memory blocks and Embeddable Logic Array Blocks (EABs) to deliver a System-on-a-Programmable-Chip (SOPC) integration platform that pre-dated modern SoC FPGAs.

Key features include 102 user I/O pins (274 maximum in the family), 0.22 µm CMOS process technology, 166.67 MHz maximum internal frequency, 0.6 ns propagation delay, 2.5 V core supply, and SameFrame pin compatibility across the FLEX 10KE family for design migration. The device is offered in the commercial 0 °C to +70 °C operating range and supports in-system programmability via the IEEE 1149.1 JTAG boundary-scan interface and the Altera serial configuration scheme.

The EPF10K50ETC144-3 is built on a 0.22 µm four-metal-layer CMOS process, with 3.3 V tolerant I/O banks supporting LVTTL, LVCMOS, PCI, and other common interface standards of its generation. Its SRAM-based configuration memory allows unlimited reconfiguration but requires a configuration PROM or microcontroller to load the bitstream at power-up. The -3 speed grade corresponds to a faster device-bin than the -4 grade, enabling higher Fmax for clocked logic paths.

Typical applications include telecommunications line cards, industrial control and glue logic, legacy ASIC prototyping, custom DSP datapaths, and test-and-measurement front-ends. Designers value the FLEX 10KE family for deterministic pin-to-pin timing and abundant memory for small to medium-density designs where modern FPGA tools would be overkill. The 144-pin TQFP package also makes the part hand-solderable for prototyping.

When designing with this part, note that the SRAM configuration cells must be loaded from a serial or parallel PROM on every power-up; plan a configuration clock source and ensure all unused I/O pins are configured as inputs with weak pull-ups to avoid floating-input quiescent current. The SameFrame pin migration path is supported only with the 484-pin FineLine BGA package, so TQFP-144 designs are not directly migratable to higher I/O-count packages without board rework.

This page synthesizes distributor pricing from DigiKey and Mouser, drop-in alternatives within the FLEX 10KE family, and practical design notes not found in the manufacturer datasheet - all cross-referenced against XAIPART's internal FLEX 10K part database.

典型應用

EPF10K50ETC144-3 適用於 6 應用s: Telecommunications Line Cards, Industrial Glue Logic and Bus Controllers, Legacy ASIC Prototyping, Custom DSP Datapaths, Test and Measurement Equipment, Educational and FPGA Training Platforms.

🌐

Telecommunications Line Cards

The EPF10K50ETC144-3's 50K-gate logic capacity, 360 LABs, and embedded memory blocks make it well suited to mid-1990s through mid-2000s telecom line-card designs implementing TDM framing, HDLC controllers, and ATM segmentation-and-reassembly (SAR) engines. Its 166.67 MHz Fmax and 0.6 ns propagation delay are sufficient for E1/T1 and 155 Mbps STM-1/OC-3 datapaths. The 102 I/O pins in the TQFP-144 package interface directly to parallel bus framer ICs and TDM backplanes. Designers benefit from the device's deterministic, register-rich architecture which simplifies timing closure for synchronous serial protocols. The same die also supports SameFrame pin migration to the 484-FineLine BGA package when higher I/O is required.

🏭

Industrial Glue Logic and Bus Controllers

The EPF10K50ETC144-3 was widely deployed as a flexible 'glue logic' replacement for multiple 74-series TTL parts on industrial control boards, implementing custom address decoding, wait-state generation, and bus arbitration between microprocessors, memory, and peripherals. Its 102 user I/O in the TQFP-144 package comfortably accommodate 8- and 16-bit ISA-style bus bridging plus dedicated control signals. The SRAM-based configuration lets factories re-spin logic without respinning PCBs - particularly valuable in long-lifecycle industrial products. The 0 °C to +70 °C commercial temperature grade suits factory-floor enclosures; engineers needing wider ranges should look at EPF10K50ETI144 (industrial -40 °C to +85 °C) or EPF10K50EQI240-2N family members.

🖥️

Legacy ASIC Prototyping

The 50K-gate density and 0.6 ns propagation delay of the EPF10K50ETC144-3 are ideal for prototyping ASIC designs of similar complexity before committing to mask costs. Engineers can drop RTL into the FLEX 10KE fabric, validate real-world timing at near-ASIC speeds (166.67 MHz Fmax), and iterate on the bitstream in minutes via JTAG. The 144-TQFP package is hand-solderable on prototype boards, eliminating the need for BGA rework equipment during bring-up. The embedded memory (40,960 bits) absorbs small FIFOs and register files common in custom ASICs. Quartus II (legacy software) supports this family, though modern Quartus Prime has dropped FLEX 10KE support.

📻

Custom DSP Datapaths

The EPF10K50ETC144-3's 360 LABs and 40,960 embedded memory bits enable moderate-density digital signal processing - FIR/IIR filters, FFT butterfly engines, and baseband demodulators. While lacking dedicated DSP blocks (which appeared in later Stratix families), the fabric supports efficient time-multiplexed MAC implementations at 100+ MHz sample rates for audio and low-MHz IF processing. The 144-TQFP package suits hand-built SDR prototypes and audio DSP evaluation boards. Designers can use Quartus II's MegaWizard to instantiate parameterized FIR/IIR IP cores that map to the FLEX 10KE's EAB blocks. For modern DSP workloads, Cyclone V with dedicated DSP blocks is preferred.

🔧

Test and Measurement Equipment

The EPF10K50ETC144-3's high I/O count (102 pins), fast propagation delay, and reconfigurable fabric make it well suited to test-and-measurement instruments - logic analyzer probes, pattern generators, protocol exercisers, and custom fixture controllers. Engineers can program stimulus patterns, bus monitors, or timing-critical measurement sequences directly into the fabric and reconfigure between tests via JTAG. The 2.5 V core with 3.3 V-tolerant I/O interfaces cleanly to TTL/CMOS test buses of its era. SameFrame pin migration to 484-BGA allows easy scaling of channel count. The commercial temperature grade is sufficient for laboratory environments; industrial temperature variants are required for field-deployed testers.

🎓

Educational and FPGA Training Platforms

The EPF10K50ETC144-3 remains useful in university FPGA curriculum and self-study where the simplicity of the FLEX 10KE architecture (no hard cores, no transceivers) helps students learn fundamentals of RTL synthesis, timing closure, and bitstream configuration without tool-chain complexity. The TQFP-144 package is hand-solderable on breadboard-friendly PCBs and works with Altera's classic ByteBlaster or BitBlaster download cables. Quartus II Web Edition (legacy free tool) supports this device. The 50K-gate density exercises real-world floorplanning and resource budgeting. Many vintage Altera development kits and academic FPGA boards shipped with this exact part.

What is the EPF10K50ETC144-3?
The EPF10K50ETC144-3 is a 50,000-gate member of Intel/Altera's FLEX 10KE family of SRAM-based FPGAs, supplied in a 144-pin TQFP package. According to the Altera FLEX 10KE datasheet, it provides 2,880 logic cells, 40,960 bits of embedded memory, 360 LABs, and 102 user I/O pins - the first family to combine embedded memory and logic in a System-on-a-Programmable-Chip (SOPC) architecture.
How many user I/O pins does the EPF10K50ETC144-3 have?
The EPF10K50ETC144-3 exposes 102 user I/O pins in its 144-pin TQFP package. According to the FLEX 10KE datasheet, the family maximum is 274 I/O pins, but the 144-TQFP package variant specifically exposes 102; designers needing more I/O must select the 208-pin, 240-pin, 256-pin, or 484-pin packages in the same family.
What is the maximum operating frequency of EPF10K50ETC144-3?
The EPF10K50ETC144-3 is rated for a maximum internal frequency of 166.67 MHz with a 0.6 ns propagation delay (per the Altera datasheet specifications reported by FPGAkey). A separate distributor summary on DigChip lists 66.67 MHz; the 166.67 MHz figure is the family Fmax for the -3 speed grade. Verify against the timing-model section of the datasheet for the specific logic path of your design.
Where can I download the EPF10K50ETC144-3 datasheet PDF?
The EPF10K50ETC144-3 datasheet is hosted on datasheets.com at https://www.datasheets.com/intel/epf10k50etc144-3 and mirrored on pdf.support (Altera-hosted PDF). Because the FLEX 10KE family is end-of-life, the datasheet may need to be retrieved from Altera/Intel legacy documentation archives or third-party FPGA archives such as FPGAkey and Octopart.
Is the EPF10K50ETC144-3 still in production?
No. The FLEX 10KE family, including the EPF10K50ETC144-3, was discontinued by Altera (now Intel FPGA) and is in obsolete lifecycle status as of 2026-09-11. Remaining stock is available only through distributors and the secondary market; new designs should migrate to Cyclone IV/V or MAX 10 family equivalents using Altera/Intel migration guides.
What is the difference between EPF10K50ETC144-3 and EPF10K50ETC144-3N?
The EPF10K50ETC144-3N suffix indicates a lead-free (Pb-free) / RoHS-compliant version of the same FLEX 10KE 50K-gate FPGA in the 144-TQFP package. According to Altera's legacy ordering scheme, the -3N part is the RoHS-compliant drop-in replacement for the original -3 part, with identical electrical and timing specifications - only the lead-finish composition differs.
What is the best drop-in replacement for EPF10K50ETC144-3?
The closest drop-in replacement for the EPF10K50ETC144-3 within Intel's FLEX 10KE family is the EPF10K50ETC144-3N, the lead-free version of the same die in the same 144-TQFP package. For new designs, Intel recommends migrating to the MAX 10 family (e.g., 10M08DAF256) which provides higher density, non-volatile configuration, and modern I/O standards, though this is a board redesign rather than a true drop-in.
EPF10K50ETC144-3 vs EPF10K50VRI240-4N - which should I choose?
The EPF10K50ETC144-3 (144-TQFP, 102 I/O, -3 speed grade) and EPF10K50VRI240-4N (240-RQFP, more I/O, -4 speed grade) are both FLEX 10KE 50K-gate FPGAs. Choose EPF10K50ETC144-3 for designs needing maximum internal frequency in a hand-solderable TQFP; choose EPF10K50VRI240-4N for designs requiring more user I/O. They are NOT pin-to-pin drop-in compatible due to the different package pin counts (144 vs 240).
What is the price of EPF10K50ETC144-3 as of 2026?
As of 2026-09-11, the EPF10K50ETC144-3 is priced at approximately USD 45.50 in single-unit quantities on the secondary market, dropping to USD 29.90 at the 1000-piece break (per available distributor listings on Mouser and FPGAkey). Because the part is obsolete, pricing varies significantly by lot date code, lead-finish, and RoHS status; quote-based sourcing is recommended for production volumes.
Is the EPF10K50ETC144-3 in stock at major distributors?
Stock of EPF10K50ETC144-3 is highly variable because the part is obsolete. As of 2026-09-11, DigiKey lists the part with lead time on quote, and secondary distributors such as Dyethin, Microchip-Price, and ICs-100 carry limited inventory. For volume production, plan for 8-16 week lead times or migrate to an active family.
What package does the EPF10K50ETC144-3 use?
The EPF10K50ETC144-3 uses a 144-pin Thin Quad Flat Pack (TQFP) with 0.5 mm lead pitch, also referred to as 144-LQFP in the DigiKey listing. The 'T' suffix in 'ETC144' indicates TQFP packaging per the Altera legacy ordering scheme; 'C' denotes commercial temperature grade; '144' is the pin count.
What is the difference between the -3 and -4 speed grades in FLEX 10KE?
In Altera's FLEX 10KE ordering scheme, the -3 speed grade is faster (higher Fmax, lower propagation delay) than the -4 grade. The EPF10K50ETC144-3 is the faster -3 bin; the EPF10K50ETC144-4 would be the slower -4 bin. Both are pin-compatible in the 144-TQFP package, allowing engineers to choose the speed grade that meets timing without PCB changes.
Can the EPF10K50ETC144-3 be used for ASIC prototyping?
Yes, the EPF10K50ETC144-3 was widely used for ASIC prototyping in the late 1990s and early 2000s. With 2,880 logic cells and 40,960 bits of embedded memory, it can absorb medium-complexity ASICs - glue logic, peripheral controllers, and modest DSP datapaths. Modern prototyping should use Cyclone IV/V or MAX 10 for higher density and modern tool support (Quartus Prime).
What configuration memory does the EPF10K50ETC144-3 require?
The EPF10K50ETC144-3 uses volatile SRAM configuration memory, which must be re-loaded from an external EPC serial configuration PROM or a microcontroller on every power-up via the Altera FLEX configuration scheme. Without a valid bitstream, all I/O pins remain tri-stated and logic functions are undefined. Modern MAX 10 or Cyclone V FPGAs use non-volatile flash configuration, eliminating this requirement.
What are the key specifications of EPF10K50ETC144-3 that engineers should know?
The EPF10K50ETC144-3 delivers 50,000 typical gates, 2,880 logic cells, 40,960 embedded memory bits, 360 LABs, 102 user I/O in 144-TQFP, 166.67 MHz max internal frequency, 0.6 ns propagation delay, 2.5 V core, 0.22 µm CMOS process, and 0 °C to +70 °C commercial temperature. It supports JTAG IEEE 1149.1 boundary scan, SameFrame pin migration with 484-FineLine BGA variants, and uses SRAM-based configuration requiring an external EPC PROM at power-up.

Choose the EPF10K50ETC144-3 when you need a mid-density 50K-gate SRAM-based FPGA in a hand-solderable TQFP-144 package with the fastest -3 speed grade of the FLEX 10KE family, and you are maintaining a legacy design that already provisions an external EPC configuration PROM. Choose the EPF10K50ETC144-3N instead for any new build requiring RoHS/Pb-free compliance - identical die, same TQFP-144 footprint, drop-in compatible. Choose the EPF10K30ETC144-3 if your design only needs 30K gates and you want to reduce cost at the same speed grade. For new designs with no legacy constraint, migrate to Intel MAX 10 (10M08SAE144) which provides non-volatile flash configuration, an integrated ADC, and modern Quartus Prime tool support, though this requires a board redesign. All five recommended alternatives share the TQFP-144 footprint, enabling PCB reuse across speed grade and density options.

設計說明

The EPF10K50ETC144-3 requires two supplies: VCCINT at 2.5 V (±5%) for the core logic and VCCIO at 3.3 V (±5%) for the I/O banks. Place 100 nF decoupling capacitors as close as possible to every VCCINT and VCCIO pin pair, with bulk 10 µF tantalum capacitors at the supply-entry points. Power-on sequencing: VCCINT should reach 90% of nominal before VCCIO reaches 1.0 V to prevent I/O latch-up; consult the FLEX 10KE datasheet for recommended sequence.

Because the FLEX 10KE family uses SRAM configuration memory, the EPF10K50ETC144-3 must be re-loaded from an external EPC configuration PROM (e.g., EPC2, EPC8) or a microcontroller on every power-up. Without a valid bitstream, all I/O pins tri-state and logic is undefined - downstream devices can be damaged by simultaneous outputs. Always instantiate a configuration controller in the design and route nSTATUS, nCONFIG, CONF_DONE, DCLK, and DATA0 to the configuration source. Allow a minimum of 100 µs for the FPGA to begin accepting configuration after power-on reset.

The 144-pin TQFP uses 0.5 mm lead pitch and benefits from a 4-layer PCB with a continuous ground plane beneath the device. Route all 102 user I/O signals on inner or outer layers with 50 Ω controlled impedance if any signals exceed 50 MHz. Keep JTAG signals (TDI, TMS, TCK, TDO) short and isolated from switching outputs to avoid programming failures. Use a 10 kΩ pull-up on nCONFIG and a 10 kΩ pull-up on nSTATUS (open-drain) per the FLEX 10KE reference schematic.

I/O banks on the FLEX 10KE support LVTTL, LVCMOS, and PCI signaling at 3.3 V. Each bank can be independently supplied via VCCIO pins; mixing voltage standards across banks is permitted but requires separate VCCIO rails. Configure unused I/O pins as inputs with weak pull-ups enabled to minimize quiescent current and reduce EMI. The -3 speed grade supports 16-bit-wide LVTTL interfaces at 100+ MHz; verify timing closure in Quartus II TimeQuest before committing to layout.

When migrating from TQFP-144 to higher-density packages in the same FLEX 10KE family, the SameFrame pin-out guarantees compatibility only for the 484-pin FineLine BGA package. Migration from 144-TQFP to 240-QFP or 256-BGA requires PCB rework. For new designs, consider Intel's MAX 10 family (10M08/10M16) which provides non-volatile flash configuration, eliminating the external EPC PROM and reducing BOM cost.
