LFE2-6E-6T144I - 6K LUT FPGA, 90 I/O, 1.2 V | Lattice
MPN: LFE2-6E-6T144I ✓ Hoạt độngLFE2-6E-6T144I Tóm tắt
An FPGA is a reconfigurable digital semiconductor that contains configurable logic blocks and programmable interconnect. Unlike a fixed-function microcontroller or application-specific integrated circuit, an FPGA can be programmed after manufacture to implement control logic, data paths, interfaces, and algorithms. The ECP2 family belongs to the broader FPGA and programmable-logic hierarchy, combining flexible parallel hardware with configuration-based design updates.
The LFE2-6E-6T144I provides 6K logic elements, 90 I/O, and 56,320 RAM bits according to DigiKey and Mouser results. One supplier result also identifies 750 logic array blocks or configurable logic blocks, while the available data reports a 1.14 V to 1.26 V supply range and an operating junction temperature beginning at -40 °C. The -6 speed grade identifies the device speed option, but the supplied data does not establish the complete timing table, configuration interface details, or absolute maximum ratings.
Typical uses include industrial control logic, sensor and acquisition systems, communications interface aggregation, low-power signal processing, and embedded instrumentation. The 90-I/O count provides substantial board-level connectivity for buses, status signals, control outputs, and external interfaces. The 56,320 RAM bits can support buffering, packet storage, counters, and small data tables, while the FPGA architecture allows parallel operations without relying on sequential processor execution.
When designing around this device, verify the exact pinout, configuration memory interface, clock requirements, supported I/O standards, and bank voltage constraints in the LatticeECP2/M family data sheet. Do not infer pin compatibility solely from a matching package. The supplied search data supports the core resource and package claims, but not a complete manufacturer-qualified replacement list.
This page combines verified distributor specifications, application guidance, and design cautions for engineers evaluating the LFE2-6E-6T144I. It distinguishes documented facts from unavailable parameters so procurement and hardware decisions can be made without inventing electrical or timing data.

Ứng dụng tiêu biểu
LFE2-6E-6T144I phù hợp cho 6 Áp dụngs: Industrial Control Logic, Sensor and Data Acquisition, Communications Interface Aggregation, Embedded Signal Processing, Programmable Timing and Sequencing, Low-Power Embedded Instrumentation.
Industrial Control Logic
The LFE2-6E-6T144I fits industrial control logic that requires deterministic parallel decision-making and a generous connection count. Its verified 6,000 logic cells and 90 I/O can support machine-state logic, interlocks, sequencing, actuator commands, and diagnostic inputs without relying on a CPU for every real-time decision. The 56,320 RAM bits provide local storage for counters, status histories, and small lookup tables. The 1.14 V to 1.26 V supply range is useful for tightly controlled embedded rails, but the designer must confirm I/O-bank voltages and industrial temperature limits in the family data sheet.
Được đề xuất
Sensor and Data Acquisition
The LFE2-6E-6T144I is suitable for parallel sensor acquisition and signal conditioning when the design benefits from programmable hardware timing. The available 90 I/O can connect digital sensors, control lines, and acquisition peripherals, while the verified 56,320 RAM bits can buffer samples or support event windows. Its DSP capability makes it useful for parallel filtering or arithmetic pipelines, although the supplied data does not specify individual DSP block resources. Engineers should define clocking, input thresholds, conversion latency, and data framing before assigning pins, because those requirements depend on the complete manufacturer electrical specification.
Được đề xuất
Communications Interface Aggregation
The LFE2-6E-6T144I can aggregate multiple digital communication interfaces and protocol-related control logic when a compact programmable-logic implementation is preferred. Its 90 I/O and 6,000 logic cells provide a substantial routing and logic budget for parallel datapaths, status registers, framing logic, and interface adapters. The ECP2 architecture is not automatically compatible with every high-speed serial protocol, so protocol signaling, clock domains, and I/O standards must be verified against the datasheet. This part is best considered where moderate logic complexity and parallel connectivity matter more than a very large FPGA resource count.
Được đề xuất
Embedded Signal Processing
The verified DSP capability and programmable logic resources make the LFE2-6E-6T144I relevant for fixed-point filtering, digital control, and parallel signal-processing pipelines. The 6,000 logic cells can implement control and sequencing around the DSP function, while 56,320 RAM bits can provide local buffers or coefficient storage. A design should document fixed-point widths, pipeline latency, clock frequency, and resource sharing before relying on performance. The supplied distributor data does not state multiplier dimensions or timing margins, so those values must be obtained from the LatticeECP2/M documentation and validated with post-layout timing analysis.
Được đề xuất
Programmable Timing and Sequencing
The LFE2-6E-6T144I is appropriate for systems that require event sequencing, pulse generation, timing windows, and hardware coordination alongside a microcontroller. Its 6,000 logic cells and 90 I/O allow independent logic channels to run in parallel, reducing reliance on processor interrupt latency for time-critical events. The verified -6 speed designation provides a defined ordering option, but actual timing closure depends on the selected clock, I/O standards, pin placement, and external components. Validate every timing path with the final device settings and board-level constraints.
Được đề xuất
Low-Power Embedded Instrumentation
The LFE2-6E-6T144I can serve as the programmable control core in compact instrumentation when moderate logic capacity, DSP support, and numerous external connections are needed. Its 1.14 V to 1.26 V operating range fits low-voltage system rails, while the 144-LQFP package exposes substantially more pins than a small QFN device. Instrumentation designs should still verify quiescent power, dynamic power, configuration retention, and unused-pin requirements from the complete data sheet. The supplied source set does not provide power consumption or quiescent-current values, so those figures must not be estimated.

Ghi chú thiết kế
Design the power tree from the documented 1.14 V to 1.26 V operating range, then separately verify core, configuration, and I/O-bank requirements in the LatticeECP2/M data sheet. The supplied snippets do not identify regulator topology, quiescent current, or dynamic power, so do not select a supply based only on the nominal 1.2 V label. Include local decoupling, sequencing, and voltage monitoring appropriate to the final configuration method.
Reserve the full 144-LQFP land pattern and confirm every pin function against the manufacturer package drawing. The verified sources establish a 20 mm x 20 mm surface-mount package but do not provide the complete numbered pin table. Check pin 1 orientation, exposed power and ground assignments, configuration pins, clock inputs, and I/O-bank voltage limits before routing. A matching package name alone is not sufficient evidence of drop-in compatibility.
Do not treat the LFE2-6E-6T144I and LFE2-6E-6TN144I as interchangeable solely because distributor snippets show similar 6K LUT, 90 I/O, DSP, and 1.2 V descriptions. Confirm the ordering suffix, package drawing, timing grade, configuration interface, and all pin functions in Lattice documentation. Also verify the upper operating temperature; the supplied data only establishes the lower operating junction temperature of -40 °C.
Thông tin tuân thủ
The supplied verified snippets do not explicitly state RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals status. Confirm current compliance documentation for the exact MPN.
