部品番号: LFE2-6E-6TN144I ✓ 生産中LFE2-6E-6TN144I 概要
An FPGA is a programmable-logic semiconductor whose digital function is defined by loading a configuration bitstream into on-chip memory. Within the semiconductor hierarchy, the LFE2-6E-6TN144I belongs to the ECP2 family of field-programmable gate arrays, placing it below programmable logic devices and above fixed-function logic integrated circuits. This distinction allows one PCB design to support firmware-driven changes in timing, interfaces, control algorithms, or system behavior without replacing the physical device.
The device provides 6,000 logic cells and 90 user I/O in a surface-mount 144-pin LQFP package measuring 20 mm by 20 mm. A 1.2 V core operating voltage supports low-power logic implementation, and the -6 speed grade targets designs requiring more timing margin than slower ECP2 grades. The 90 I/O count is particularly useful for parallel control, data acquisition, industrial interfaces, and board-level integration where a programmable device must directly connect to multiple external signals.
The ECP2 architecture provides programmable logic together with dedicated block RAM and DSP resources, allowing designers to implement control logic, counters, state machines, data pipelines, signal conditioning, and fixed-point processing in one device. The manufacturer classifies the part in the ECP2 family and identifies 6,000 cells, a 144-LQFP package, 90 I/O, and a 90 nm process node. This combination provides a practical platform for moderately complex digital systems where a small microcontroller is insufficient or an application-specific ASIC would not justify the development cost.
Typical uses include industrial automation controllers, sensor and measurement interfaces, communication equipment, embedded data acquisition, motor and machine-control logic, and general-purpose digital signal conditioning. Its 90 I/O can simplify board partitioning when multiple buses, discrete inputs, and outputs must be consolidated. The 20 mm by 20 mm LQFP also remains practical for conventional multilayer PCB assembly methods rather than requiring fine-pitch BGA assembly.
Designers should confirm the exact pin assignments, supported I/O standards, configuration requirements, clocking resources, and recommended power and decoupling networks against the manufacturer ECP2 documentation before layout release. Pay particular attention to the -6 speed designation, 1.2 V core supply, industrial-temperature ordering code, and package pinout. Configuration storage, JTAG access, programming voltage, and unused-pin treatment must also be validated for the selected board architecture.
This product page combines the exact ECP2 ordering information with practical selection guidance, alternative cross-references, parameter comparisons, and design-oriented implementation notes. These resources help engineers identify whether the LFE2-6E-6TN144I fits the required logic density, I/O count, package, speed grade, and environment before beginning a new programmable-logic design.

主な用途
LFE2-6E-6TN144I の用途: 6 件s: Industrial Automation Controller, Data Acquisition System, Communications Interface, Motor and Machine Control, Signal Conditioning and DSP, Embedded Test Equipment.
Industrial Automation Controller
The LFE2-6E-6TN144I suits machine-control logic that must combine many parallel sensor inputs, actuator outputs, and deterministic state machines in one device. Its 6,000 logic cells provide room for sequencing, interlocking, counters, communications, and diagnostic logic, while 90 I/O reduce the number of external interface components. The -6 speed grade supports designs requiring greater timing margin than the -5 grade, and the industrial-temperature suffix suits equipment expected to operate above commercial-temperature limits. Place the FPGA near protected I/O circuitry and route critical timing paths away from switching-node activity.
おすすめ
Data Acquisition System
The LFE2-6E-6TN144I can implement parallel data capture, digital filtering, trigger control, and interface conversion in a compact instrument. With 6,000 configurable logic cells, it can coordinate multiple data paths without requiring a separate controller for every protocol function. The 90 I/O provide substantial board-level connectivity for sample buses, clocks, status signals, and communications, while the 144-pin LQFP supports conventional surface-mount assembly. Engineers should use the manufacturer timing tables to confirm acquisition-clock rates and should treat analog-to-digital conversion performance as a system-level specification rather than an FPGA characteristic.
おすすめ
Communications Interface
The LFE2-6E-6TN144I is appropriate for custom communication bridges, protocol translators, test interfaces, and equipment that needs programmable framing or bit manipulation. Its 6,000 logic cells can implement parallel-to-serial conversion, packet filtering, clock-domain-related control, and command decoding, while 90 I/O offer enough connections for multiple buses and status lines. The -6 grade provides more timing headroom than the -5 option for demanding interfaces. Final design work must verify each supported I/O standard, voltage tolerance, clocking topology, and maximum interface rate in the ECP2 documentation.
おすすめ
Motor and Machine Control
The LFE2-6E-6TN144I can implement motion sequencing, pulse generation, encoder decoding, fault handling, and safety interlocks in programmable logic. Its 90 I/O provide direct access to position sensors, stepper or motor-control signals, limit switches, and diagnostic outputs, while the 6,000 logic cells allow multiple control tasks to operate concurrently. The industrial-temperature ordering option is relevant to equipment with an elevated internal ambient temperature, but enclosure heating, conducted noise, and motor-transient protection remain external design requirements. Use differential routing and grounded return paths for sensitive encoder and control signals.
おすすめ
Signal Conditioning and DSP
The LFE2-6E-6TN144I supports digital filtering, correlation, counting, waveform generation, and fixed-point signal-processing tasks through its ECP2 programmable logic and DSP resources. Six thousand logic cells allow multiple pipeline stages to coexist with control logic, and the -6 grade provides additional timing margin for pipelined implementations. The 144-pin LQFP package also exposes numerous I/O for parallel data input, coefficient loading, and synchronized test outputs. Designers should estimate DSP, block RAM, and routing requirements before committing to the 6,000-cell device, because adding arithmetic stages can consume resources even when the package has sufficient I/O.
おすすめ
Embedded Test Equipment
The LFE2-6E-6TN144I can implement programmable stimulus generation, pattern sequencing, response capture, and communication for embedded test systems. Its 90 I/O allow parallel connection to devices under test, while 6,000 logic cells support timing tables, counters, and protocol engines that adapt through configuration. The -6 speed grade is useful when test timing margins must be preserved around device-under-test stimulus. Board design should separate test clocks from digital data returns, provide controlled I/O reference voltages, and account for the LQFP package's lead geometry when planning probe access.

設計ノート
Use the TQFP-144 land pattern associated with the 20 mm by 20 mm LQFP package and route every configuration, clock, JTAG, power, and ground connection exactly as shown in the manufacturer pin table. Keep the FPGA footprint inside the board-placement outline so that both sides remain accessible for inspection and rework. Do not infer configuration or dual-purpose I/O behavior from package position alone because several ECP2 pins can have functions determined by device options.
Separate the 1.2 V core rail from the applicable I/O rails and follow the manufacturer power-supply topology, decoupling values, and sequencing requirements. Place the required bypass capacitors adjacent to their designated package pins, with short, low-inductance connections and a solid ground reference. Validate startup, configuration behavior, and supply tolerance against the ECP2 electrical tables before adding independent rail sequencing or voltage adjustment.
Assign clock-capable pins according to the ECP2 clocking rules and keep high-speed or externally clocked traces short and continuously referenced. Provide clean returns for JTAG, configuration, and optional differential interfaces, and avoid routing sensitive clocks beside switching power nodes or motor-control outputs. For multi-source or multiplexed I/O, verify the selected standards and supported data rates in the manufacturer documentation before committing to the PCB layer stack.
Do not treat a shared LQFP footprint as proof that every ECP2 ordering code is interchangeable. The LFE2-6E-6TN144C changes the temperature grade, the LFE2-6E-5TN144I changes the speed grade, and the 6SE and omitted-N ordering forms require confirmation of configuration-related options. Before substitution, compare the exact ordering table, pin description, configuration bitstream support, timing grade, and environmental requirements.
