LFE2-6E-5T144I Descripción general

The Lattice Semiconductor LFE2-6E-5T144I is a 6K-LUT ECP2 field-programmable gate array with 90 user-programmable I/O pins, 56,320 RAM bits, and a 1.2 V supply class, packaged in a 144-pin TQFP. The I suffix identifies the industrial-temperature offering, while the -5 speed grade and 144-pin package support designs requiring deterministic programmable logic in industrial embedded systems.

A field-programmable gate array, or FPGA, is a programmable semiconductor used to implement control logic, interfaces, protocol handling, datapaths, and DSP functions after board fabrication. Within the broader semiconductor hierarchy, an FPGA combines configurable logic blocks, programmable interconnect, block RAM, and I/O resources. This makes it useful when a design requires rapid revisions, parallel channels, mixed logic functions, or a compact controller that would otherwise require several fixed-function devices.

The verified product data identifies 6K LUTs, 90 I/O, 56,320 RAM bits, and a 1.2 V operating class. A 144-TQFP package provides 144 physical leads and a surface-mount form factor suitable for automated PCB assembly. The available listing data also reports 90 I/O and a 144-TQFP package, while detailed pin assignments, block counts, pin standards, and configuration interface details require the manufacturer datasheet before layout or replacement approval.

Typical ECP2 applications include industrial control, instrumentation, embedded communication, motion-control logic, and general-purpose programmable signal conditioning. The programmable architecture lets designers consolidate parallel control functions into one FPGA, while the 90 I/O count supports external memory, converters, communications transceivers, status indicators, and actuator or sensor interfaces. Designers should verify voltage tolerances and pin multiplexing against the device-specific pinout rather than relying only on the package name.

For robust implementation, begin with the manufacturer pinout and power specifications, then define bank voltage constraints before assigning external interfaces. Place decoupling capacitors close to every supply pin, preserve the package footprint and exposed thermal requirements specified by the manufacturer, and program the device using the supported Lattice toolchain. A hardware replacement is valid only after checking pinout, I/O standards, supply rails, timing, configuration interface, and temperature grade.

This product page consolidates verified distributor and cross-reference information, practical selection guidance, and design cautions for engineers evaluating the LFE2-6E-5T144I. Exact price, lead time, stock status, pin-level electrical limits, and full timing/resource parameters are not supplied consistently in the provided source data and should therefore be confirmed before procurement or PCB release.

Aplicaciones típicas

LFE2-6E-5T144I es adecuado para 7 aplicacións: Industrial Control Logic, Programmable Signal Conditioning, Communication Interface Consolidation, Motion and Motor Control, Embedded Instrumentation, Programmable Data Acquisition, Compact Programmable System Control.

🏭

Industrial Control Logic

The LFE2-6E-5T144I fits industrial control designs that need programmable sequencing, interlocks, state machines, and multiple external control lines. Its 6K LUT capacity provides logic resources for parallel control paths, while 90 user-programmable I/O can connect sensors, relay drivers, status indicators, and actuators. The 1.14 V to 1.26 V supply range and -40°C to +100°C junction-temperature specification support industrial design planning, although exact I/O voltage limits and timing must be checked in the datasheet.

📟

Programmable Signal Conditioning

Use the FPGA when several sensor channels require parallel conversion control, digital filtering, timing coordination, or programmable signal routing. The 6K LUT and 56,320 RAM-bit resources can consolidate control and buffering functions that would otherwise require multiple fixed-function devices. Its 90 I/O supports converters, amplifiers, switches, and digital sensors, while the 144-pin TQFP package is convenient for automated assembly. Designers must verify supported voltage standards and acquisition timing before implementation.

🌐

Communication Interface Consolidation

The LFE2-6E-5T144I can implement protocol formatting, byte framing, FIFO control, interrupt logic, and data routing for embedded communications. With 90 I/O and 6K LUTs, it is suitable for bridging processors to transceivers or managing several low-speed interfaces in parallel. The 1.2 V nominal core supply is compatible with modern digital power planning, but external transceiver voltage domains, timing margins, and configuration behavior must be verified against the manufacturer documentation.

⚙️

Motion and Motor Control

The FPGA is suitable for deterministic motion-control assistance, including encoder decoding, step/direction sequencing, pulse counting, fault handling, and protection interlocks. The 6K LUT capacity supports parallel state machines, and the 90 I/O can expose encoder, capture, enable, direction, and status signals. The industrial junction-temperature range is useful for embedded automation, but motor transients, isolation, ground returns, and output-drive requirements should be handled by appropriate external hardware.

🖥️

Embedded Instrumentation

Instrumentation systems can use the LFE2-6E-5T144I for measurement sequencing, calibration tables, trigger routing, status reporting, and front-panel control. The 56,320 RAM bits provide on-chip storage for small data buffers or configuration state, while 90 I/O supports converters, displays, switches, and communication ports. The 144-TQFP package simplifies standard surface-mount assembly, but analog input isolation, reference quality, calibration storage, and timing accuracy are system-level responsibilities rather than automatic FPGA functions.

📊

Programmable Data Acquisition

The device can coordinate multiple converters, trigger signals, sample counters, and data-transfer routines in compact acquisition equipment. Its 6K LUTs support control and timing logic, while 90 I/O provide connectivity to converters, memory, and host interfaces. The 1.14 V to 1.26 V operating range and identified industrial temperature class support robust digital implementations, provided the selected I/O banks and external interface voltage levels are compatible with the target system.

🧩

Compact Programmable System Control

LFE2-6E-5T144I can act as a compact supervisory controller for board bring-up, power sequencing, watchdog behavior, fault aggregation, and peripheral control. Its 90 I/O leaves substantial external connectivity for status LEDs, reset signals, interlock inputs, and bus transceivers. The device is most useful when several small control tasks need configurable logic rather than separate fixed-function controllers. Firmware-free configuration and diagnostic coverage should be designed into the FPGA implementation and verified with the supported programming flow.

The provided search data also links to a Lattice user-reference-manual result, but its page count should not be treated as an authoritative datasheet specification. Use the manufacturer document for final pinout and electrical details.
Where can I find the LFE2-6E-5T144I pinout?
The LFE2-6E-5T144I pinout is not included in the supplied verified data, so a complete pin list cannot be fabricated. The package is identified as 144-pin TQFP, and the source data reports 90 user-programmable I/O pins. Download the LatticeECP2/M datasheet and use the exact device pin table before assigning power, ground, configuration, clock, and user I/O signals.
Where can I buy LFE2-6E-5T144I online?
You can search for LFE2-6E-5T144I at Mouser, DigiKey, Octopart, and the other verified distributor listings. The supplied sources do not provide a consistent numeric price or current stock quantity, so the quantity-one price is marked [DATA_NEEDED: current unit price]. Confirm authorized-source status, date, lead time, and package condition with the selected distributor before ordering.
What is the price of LFE2-6E-5T144I?
A verified current price for LFE2-6E-5T144I is not available in the supplied data. The Mouser and DigiKey pages identify the component and provide pricing interfaces, but their snippets do not expose usable numeric tier prices. Therefore, the pricing tiers remain marked [DATA_NEEDED: current unit price] and related quantity-break values rather than relying on an estimate.
What is the lead time for LFE2-6E-5T144I?
The verified data does not state a numeric manufacturer or distributor lead time for LFE2-6E-5T144I. Distributor pages may show availability or quote terms dynamically, but those values were not included in the supplied search results. Request a written lead time and stock confirmation from an authorized distributor before committing a production schedule.
Is LFE2-6E-5T144I in stock?
Stock status cannot be confirmed from the supplied snippets. DigiKey states that the component can be ordered and shipped, while other listings provide availability or stock-search interfaces, but no current numeric inventory is given. Treat the part as unconfirmed until the distributor shows live stock, and use the seller-confirmed quantity as the procurement basis.
LFE2-6E-5T144I vs LFE2-6E-5TN144I - which is better?
LFE2-6E-5TN144I is the same Lattice ECP2 144-pin TQFP family listed with the same 90 I/O and 56,320 RAM-bit class, and the cross-reference data describes its terminals and package as consistent with the target. The exact ordering-code and temperature details should still be checked in the manufacturer datasheet before substitution. For a drop-in decision, confirm speed grade, temperature suffix, pinout, supply limits, and configuration behavior.
What is the difference between LFE2-6E-5T144I and LFE2-6E-5TN144I?
The verified cross-reference identifies LFE2-6E-5TN144I as a TQFP-144 alternative with consistent terminals, package, and main functional characteristics. The supplied data does not provide a complete suffix-by-suffix comparison, so the exact industrial-temperature, speed, and qualification differences cannot be quantified here. Use the device ordering guide and datasheet to confirm whether the N suffix changes the required production temperature or qualification criteria.
When should I choose LFE2-6E-5T144I over LFE2-6E-5TN144I?
Choose LFE2-6E-5T144I when the production design specifically requires its documented ordering code and verified operating conditions. LFE2-6E-5TN144I may be appropriate when its manufacturer data confirms the same electrical limits, pinout, speed grade, and environmental requirements. Because the supplied cross-reference indicates package and terminal consistency, the practical selection criterion is not footprint alone but verified device qualification, temperature, supply, and lifecycle requirements.
What can replace LFE2-6E-5T144I?
LFE2-6E-5TN144I is the clearest drop-in candidate in the supplied cross-reference results because it is identified as a TQFP-144 Lattice ECP2 part with consistent terminals and package. LFE2-6SE-5T144I is also compared as a same-family 144-pin option, but its S-series feature set may differ. No cross-brand pin-compatible replacement is verified in the provided data, so a substitute must be approved after checking every pin and electrical parameter.
Is LFE2-6E-5T144I suitable for industrial control systems?
Yes, the LFE2-6E-5T144I is a reasonable candidate for industrial control because it provides 6K LUTs, 90 I/O, 56,320 RAM bits, a 1.14 V to 1.26 V supply range, and an identified -40°C to +100°C junction-temperature range. Suitability still depends on the complete I/O budget, timing closure, isolation requirements, environmental qualification, and availability of a supported Lattice configuration and programming toolchain.
How much power does the LFE2-6E-5T144I FPGA use?
The supplied data does not provide a verified core-current, I/O-current, static-power, or dynamic-power specification for the LFE2-6E-5T144I. The 1.14 V to 1.26 V operating range and 1.2 V nominal class are known, but voltage alone does not determine power. Obtain quiescent and active power values from the manufacturer datasheet and calculate board-level dissipation using the actual core and I/O loads.
Can LFE2-6E-5T144I replace LFE2-6SE-5T144I?
LFE2-6SE-5T144I is a same-family, 144-pin comparison part, but the supplied data does not establish that it is a universal drop-in replacement for LFE2-6E-5T144I. The comparison identifies related FPGA variants, while the target’s exact speed, temperature, I/O, memory, and configuration requirements must be matched individually. Treat the S-series part as a candidate only after manufacturer-level pin and parameter verification.

Notas de diseño

Use the exact LFE2-6E-5T144I package drawing and pin table before placing the 144-pin TQFP. The supplied data identifies the package as 20 x 20 mm but does not provide the pin pitch, land pattern, or pin numbering. Route supply and ground pins first, place local decoupling close to their associated pins, and preserve the manufacturer-defined footprint rather than relying on a generic TQFP symbol.

The verified operating range is 1.14 V to 1.26 V, with a 1.2 V nominal supply class. Check every bank’s allowed voltage and external interface level in the manufacturer datasheet; a low-voltage core rating does not automatically authorize 1.8 V, 2.5 V, or 3.3 V I/O. Use separate, properly filtered supplies where required and verify power sequencing, tolerances, and transient limits before layout release.

The listed junction-temperature range is -40°C to +100°C, but actual FPGA temperature depends on device activity, I/O loading, airflow, and PCB copper. Estimate worst-case board temperature during the design review, provide continuous copper around the package where the footprint permits, and avoid placing the device next to unregulated power stages or heat sources. The supplied data does not include thermal resistance or power dissipation, so those values must come from the manufacturer documentation.

Do not approve a substitute from the 144-TQFP package name alone. Verify configuration pins, power pins, I/O standards, bank voltage limits, user I/O assignment, speed grade, temperature suffix, and programming compatibility. LFE2-6E-5TN144I is the strongest verified drop-in candidate, while S-series and other speed-suffix variants require a device-by-device engineering review.
