EPF10K10TC144-3 개요

The Intel EPF10K10TC144-3 is a member of the FLEX 10K family of SRAM-based FPGAs, providing 10,000 usable gates, 576 logic elements (logic cells), and 102 user I/O pins in a 144-pin TQFP package. It is built on a 0.42 µm CMOS process and operates from a 5 V supply, with a -3 speed grade targeting commercial timing closure. The device integrates 72 logic array blocks (LABs) and embedded array blocks (EABs) for memory and complex logic functions.

A Field Programmable Gate Array (FPGA) is a semiconductor device built around an array of configurable logic blocks (CLBs), programmable interconnects, and I/O cells, allowing engineers to implement custom digital logic without fabricating an application-specific IC. Within the broader semiconductor taxonomy, an FPGA sits under programmable logic devices (PLDs) -> logic ICs -> integrated circuits. The FLEX 10K family specifically pioneered embedded array blocks (EABs), which provide on-chip SRAM for fast FIFO/RAM/CAM storage and reduce system chip count versus discrete SRAM plus CPLD designs.

Key features of the EPF10K10TC144-3 include 6,144 typical gate count marketing figure, 12,288 bits of embedded memory across EABs, in-system programmability through the IEEE 1149.1 JTAG interface, and 102 user I/O with multi-voltage I/O support (3.3 V and 5 V tolerant). The device supports configuration via configuration EPROMs, JTAG, or controller-driven serial/parallel modes. Operating junction temperature spans 0 °C to +85 °C for the commercial -3 speed grade.

The architecture combines a fine-grained logic element (LE) fabric with coarse-grained EABs of 2,048 bits each, delivering an efficient trade-off between random logic density and block-memory throughput. I/O banks support selectable drive strength and slew-rate control to simplify mixed 3.3 V / 5 V board designs. The 144-pin TQFP package exposes 102 user I/O, with the remaining pins reserved for power, ground, configuration, and JTAG signals.

Typical applications include telecommunications interface glue logic, industrial control and instrumentation, prototyping ASICs, custom peripheral controllers, and legacy digital signal preprocessing. The -3 speed grade is well suited for bus interfaces, glue logic between microcontrollers and peripherals, and pre-silicon ASIC/ASSP emulation where deterministic timing across moderate clock frequencies (up to 125 MHz internally) is sufficient.

When designing with this part, ensure JTAG chain integrity by including proper TCK pull-down and TMS pull-up resistors, and observe VCCINT/VCCIO supply sequencing. Note that the FLEX 10K family is mature but classified NRND by Intel; verify long-term availability before committing to new production designs, or plan a migration path to Cyclone series devices.

This page synthesizes distributor pricing, pin-compatible drop-in alternatives, and practical design considerations across the FLEX 10K family not consolidated in any single source.

일반적인 애플리케이션

EPF10K10TC144-3 적합 용도: 6 애플리케이션s: Bus Interface Glue Logic, ASIC/ASSP Prototyping and Emulation, Telecommunications Interface Controllers, Industrial Control and Instrumentation, Custom Peripheral Controllers, Legacy Product Repair and Sustainment.

🔧

Bus Interface Glue Logic

The EPF10K10TC144-3 fits bus-interface glue logic because it offers 102 user I/O and 576 logic cells, enough to bridge mismatched bus widths between microcontrollers, memory, and peripherals. Its 5 V tolerant I/O banks simplify interfacing with legacy 5 V devices while 3.3 V support allows connection to modern microprocessors. Compared to discrete 74-series logic, a single FPGA replaces dozens of packages and supports late-stage design changes, which is critical when bus timing is still being characterized. The -3 speed grade delivers comfortable timing margin for bus speeds up to roughly 33 MHz.

🖥️

ASIC/ASSP Prototyping and Emulation

The EPF10K10TC144-3 serves well as an ASIC prototyping vehicle thanks to its 10K usable gates, 12 Kbit embedded memory, and 102 I/O - enough capacity for moderate-complexity ASIC pre-silicon validation. Engineers map RTL into Quartus and iterate against the target ASIC's functional and timing requirements, cutting ASIC respins. The FLEX 10K architecture exposes a JTAG interface for real-time debug, and the 144-pin TQFP is convenient for socket-based prototyping boards. Use the -4 speed grade when emulating higher-frequency ASIC paths.

Telecommunications Interface Controllers

The EPF10K10TC144-3 is well suited to telecom interface controllers where 5 V I/O tolerance, deterministic logic, and moderate embedded memory are required for protocol conversion and framing. The 12 Kbit EAB memory implements small FIFOs and elastic buffers for serial protocol rate adaptation, while 102 I/O lines accommodate parallel bus interfaces to DSPs and framers. The -3 speed grade handles sub-100 MHz telecom clocks with margin. FLEX 10K's proven installed base in telecom infrastructure continues to support field repairs and legacy product extensions.

🏭

Industrial Control and Instrumentation

The EPF10K10TC144-3 is deployed in industrial control platforms where 5 V-tolerant I/O directly drives optocouplers, relays, and 24 V interface backplanes. Its 576 logic cells handle state machines for motor control, encoder decoding, and PLC I/O expansion without resorting to multiple CPLDs. Embedded EAB memory supports small lookup tables for sensor linearization or pulse-width modulation patterns. The 144-pin TQFP package is robust for industrial temperature environments within its commercial 0-85 °C range; for harsher temperatures, verify derating or select an industrial-speed-grade variant.

🔧

Custom Peripheral Controllers

The EPF10K10TC144-3 fits custom peripheral controller designs where a microcontroller needs glue logic, custom register maps, or unusual timing not supported by off-the-shelf peripherals. The 102 I/O directly interfaces to external buses, sensors, and actuators, while the 576 logic cells implement state machines, FIFOs, and protocol converters. In-system programmability via JTAG allows late-stage firmware updates without board rework. Compared to a CPLD of similar I/O count, the FLEX 10K provides substantially more memory and sequential logic for moderate-complexity controllers.

🧩

Legacy Product Repair and Sustainment

The EPF10K10TC144-3 is commonly sourced for legacy product repair programs, where original equipment manufacturers must continue to support deployed systems with 10-20 year service lifetimes. Because the FLEX 10K family is NRND but still stocked through distribution, repair depots use the part to replace damaged FPGAs on existing boards. The 144-pin TQFP footprint matches the original board, eliminating any mechanical redesign. Order the -3N variant when RoHS compliance is required for repair, or the -3 base part for legacy non-RoHS service stock.

What is the EPF10K10TC144-3 FPGA?

The EPF10K10TC144-3 is an Intel (formerly Altera) FLEX 10K family SRAM-based FPGA with 10,000 usable gates, 576 logic elements, and 102 user I/O in a 144-pin TQFP package. It operates from a 5 V supply and is built on a 0.42 µm CMOS process. The -3 suffix denotes a commercial speed grade targeting moderate clock rates up to roughly 125 MHz internal timing.

How many I/O pins does the EPF10K10TC144-3 have?

The EPF10K10TC144-3 exposes 102 user I/O pins across its 144-pin TQFP package, with the remaining 42 pins allocated to power, ground, configuration, dedicated JTAG signals, and no-connect reservations. This I/O count makes the part suitable for bus-interface glue logic and small-to-medium peripheral controllers where roughly 80-100 signal pins are required.

Where can I buy the EPF10K10TC144-3?

The EPF10K10TC144-3 is available from authorized distributors listed on Octopart and DigiKey; the part is shown as ships-today on several inventory feeds as of 2026-09-11. Common distributors include Heisener, Xecor, LCSC, and smaller franchised stockists. Note that Intel classifies FLEX 10K as NRND, so verify long-term availability before committing to new high-volume production.

What is the price of EPF10K10TC144-3 as of 2026-09-11?

As of 2026-09-11, the EPF10K10TC144-3 lists at approximately $42.42 at qty 1, scaling down to roughly $26.40 per unit at qty 1,000, based on distributor pricing aggregated from LCSC and Heisener. Pricing for legacy FLEX 10K parts varies with stock availability; obtain firm quotes from franchised distributors for production orders and confirm lead-time, since the family is no longer in full active production.

What is the lead time for EPF10K10TC144-3?

Lead time for the EPF10K10TC144-3 is generally 1-3 weeks when in distributor stock, with Heisener reporting expedited shipping delivery windows of July 15-20 and April 25-30 depending on the order. Because the FLEX 10K family is NRND, lead times can stretch when distributors exhaust last-time-buy inventory; plan ahead or qualify a Cyclone-series replacement for new designs.

Is EPF10K10TC144-3 in stock today?

Yes, multiple distributors report EPF10K10TC144-3 in stock as of 2026-09-11, including Heisener listing 5,856 pieces and Intel-branded inventory at 5,536 pieces, plus LCSC, Xecor, and Microchip-Price.com listings. Because the FLEX 10K family is NRND, stock is finite; confirm current availability at the time of order since quantities deplete as the part approaches end-of-life.

What is the difference between EPF10K10TC144-3 and EPF10K10TC144-4?

The EPF10K10TC144-3 and EPF10K10TC144-4 share the same die and 144-pin TQFP package but differ in speed grade: -3 is the standard commercial timing closure, while -4 is a faster speed grade delivering shorter propagation delays and higher Fmax on internal paths. The -4 variant is preferred when timing margin is tight; the -3 is adequate for bus glue logic, peripheral controllers, and most telecommunications interface designs running below ~80 MHz.

What is the difference between EPF10K10TC144-3 and EPF10K10ATC144-3N?

The EPF10K10ATC144-3N belongs to the higher-density EPF10K10A (sometimes labeled EPF10K10A) FLEX 10K variant, offering more usable gates and embedded memory than the EPF10K10TC144-3. Both come in the same 144-pin TQFP footprint, but the A version provides additional EABs and logic capacity for designs that exceed the base EPF10K10's 576-cell budget. Use the A variant when you need extra logic headroom without changing the PCB layout.

EPF10K10TC144-3 vs EPF10K100EQC208-2 - which is better for new designs?

The EPF10K10TC144-3 is a 10K-gate FLEX 10K part suited for legacy glue logic in the 144-pin TQFP footprint, while the EPF10K100EQC208-2 is a 100K-gate FLEX 10KE part in a 208-pin QFP, offering roughly 10× the logic capacity. Choose EPF10K10TC144-3 for legacy 144-pin TQFP boards with low gate count; choose EPF10K100EQC208-2 for new designs requiring higher density and accepting the PCB migration to 208 pins.

When should I choose EPF10K10TC144-3 over a modern Cyclone FPGA?

Choose EPF10K10TC144-3 only when you must drop into an existing 144-pin TQFP board footprint that was designed around FLEX 10K pinout, or when repairing/legacy-supporting a deployed product. For any new design, a modern Cyclone IV or Cyclone 10 LP device in a similar QFP package offers lower power, faster I/O, and active lifecycle support at comparable price points.

What is the best drop-in replacement for EPF10K10TC144-3?

The best drop-in replacement is the EPF10K10TC144-3N (lead-free variant) or EPF10K10TC144-4 (faster speed grade, same footprint), both sourced from the same Intel FLEX 10K family. For a same-footprint capacity upgrade, the EPF10K10ATC144-3N provides additional logic and EAB resources in the identical 144-pin TQFP package without requiring PCB rework.

Can a Xilinx XC3S50A-4TQG144C replace the EPF10K10TC144-3?

The Xilinx XC3S50A-4TQG144C is NOT a drop-in replacement for EPF10K10TC144-3: while both use a 144-pin TQFP package, the pinout, JTAG chain, configuration scheme, and I/O bank voltages are not pin-to-pin compatible. Migrating from FLEX 10K to Spartan-3A requires PCB redesign and a Quartus-to-ISE toolchain port; treat this as a cross-package functional equivalent, not a drop-in.

Where can I download the EPF10K10TC144-3 datasheet PDF?

The official EPF10K10TC144-3 datasheet PDF is hosted on Altera's legacy literature archive at https://www.altera.com/literature/ds/dsf10k.pdf (FLEX 10K family datasheet). Archived copies are also available via pdf.support and FPGAkey. Always reference the family datasheet together with the device-specific pinout table when designing.

Where do I find the EPF10K10TC144-3 pinout diagram?

The EPF10K10TC144-3 pinout is documented in the FLEX 10K family datasheet (DS-F10K), specifically in the TQFP-144 pin table section. XAIPART also provides an SVG pinout diagram under package_svg_key tqfp-144 for visual reference. Cross-check dedicated JTAG pins (TCK, TMS, TDI, TDO), configuration pins (nCONFIG, nSTATUS, CONF_DONE), and power/ground distribution before laying out the PCB.

Is the EPF10K10TC144-3 RoHS compliant?

Yes, the EPF10K10TC144-3 is RoHS compliant per Intel/Altera product documentation. The lead-free variant is identified by the suffix N (EPF10K10TC144-3N), which explicitly marks the RoHS-compliant ordering code. If your build requires lead-free assembly, order the -3N suffix variant to ensure compliance with RoHS-6/6 directives.

선택 가이드

Choose EPF10K10TC144-3 when you need a 10K-gate FLEX 10K FPGA for legacy board repair, drop-in replacement on existing 144-pin TQFP designs, or low-density glue logic on commercial-temperature deployments. Select the -3N variant when RoHS compliance is required, and the -4 (or -4N) when timing margins are tight at higher clock frequencies. For new designs where you have flexibility in the PCB footprint, prefer a modern Cyclone IV or Cyclone 10 LP part - they offer lower power, faster I/O, and active lifecycle support. The EPF10K10ATC144-3N is the right choice when you need more logic capacity in the same 144-pin TQFP footprint without changing the PCB.

설계 노트

The EPF10K10TC144-3 requires a stable 5 V VCCINT supply and a separate VCCIO rail that can be set to either 3.3 V or 5 V depending on the connected peripherals. Decouple each VCCINT pin with a 0.1 µF ceramic capacitor placed as close to the package as possible, plus a bulk 10-47 µF tantalum or low-ESR electrolytic on each rail. Power sequencing between VCCINT and VCCIO is not strictly required for FLEX 10K, but a common recommendation is to bring up VCCINT before or simultaneously with VCCIO to avoid I/O bus contention during configuration. For multi-FPGA boards, provide a centralized power supervisor with reset distribution to all nCONFIG pins.

Lay out the TQFP-144 footprint using 0.5 mm pitch land patterns with continuous ground and power planes on inner layers. Provide dedicated escape routing for the dedicated JTAG pins (TCK, TMS, TDI, TDO) so they can be daisy-chained across multiple devices without stubs. Route clock inputs using impedance-controlled traces (typically 50 Ω) and place termination as close to the receiver as possible. The configuration pins (nCONFIG, nSTATUS, CONF_DONE, DCLK, DATA0) should be pulled to known states with 4.7-10 kΩ resistors; the nCONFIG pin requires a 1 kΩ pull-up to VCCINT and a small capacitor (~0.01 µF) to GND for clean power-on reset.

Do not assume the EPF10K10TC144-3 is a generic drop-in for any 144-pin TQFP FPGA: the JTAG chain order, configuration pinout, and I/O bank voltages differ from Xilinx Spartan-3A and other vendors. Always re-derive pin assignments from the FLEX 10K family datasheet, not from competitor pinout tables. A common pitfall is to confuse the -3 speed grade with the -4 grade; mixing them on the same JTAG chain works but each device is timed individually. Finally, do not exceed the maximum I/O count of 102 even though the package has 144 pins - the remaining pins are power, ground, and dedicated configuration signals.
