LFE2-6E-5T144I 概要
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.

主な用途
LFE2-6E-5T144I の用途: 7 件s: 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.
おすすめ
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.
おすすめ
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.
おすすめ
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.
おすすめ
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.
おすすめ
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.
おすすめ
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.

設計ノート
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.
コンプライアンス情報
The supplied verified data does not provide RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals declarations. The industrial temperature suffix does not by itself establish AEC-Q100 qualification.
