LFE2-6E-6F256C - 6K LUT 190 I/O FPGA | Lattice Semiconductor
MPN： LFE2-6E-6F256C ✗ 停產LFE2-6E-6F256C 概覽
An FPGA is a semiconductor device whose digital behavior is defined by loading a configuration bitstream after manufacture. The ECP2 family belongs to the broader programmable-logic hierarchy and combines LUT-based combinational logic, embedded block RAM, programmable I/O, and dedicated DSP resources. This combination allows designers to implement parallel data paths, protocol handling, state machines, and control functions on one device.
The verified listing identifies the LFE2-6E-6F256C as a 6K-LUT device with 190 I/O and DSP support at 1.2 V. Independent indexing also identifies the device as a 256-pin FBGA using 90 nm technology. These figures make the part relevant to industrial control, communications, test equipment, consumer electronics, and embedded systems that need more routing resources and I/O than a small programmable logic device can provide.
The LFE2-6E-6F256C belongs to the LatticeECP2 family. Its large I/O count can simplify board-level connections when the design uses multiple buses, parallel data interfaces, or multiple external peripherals. The 55 Kb block RAM figure applies explicitly to the verified LFE2-6E-6FN256C family member; the supplied search data does not state that figure for LFE2-6E-6F256C, so that value is not used as a target specification here.
For a new board, engineers should verify power rails, configuration interface support, I/O standards, pin constraints, and the exact package drawing before layout. Because the available evidence confirms 256 FBGA and 190 I/O but does not provide a complete manufacturer pin table, detailed ball assignments and electrical limits should be taken from the official Lattice documentation rather than inferred from distributor summaries.
This page consolidates distributor availability, family-level technical context, procurement questions, and design cautions. It distinguishes verified facts from unavailable details and avoids treating generic FPGA advice as device-specific performance data. Check current distributor inventory and quote terms directly before committing a production BOM.

典型應用
LFE2-6E-6F256C 適用於 6 應用s: Industrial Control and Automation, Parallel Data Acquisition and Signal Conditioning, Communications and Protocol Bridging, Test and Measurement Instrumentation, Embedded Video and Image Processing, Consumer and Embedded Logic Modules.
Industrial Control and Automation
The LFE2-6E-6F256C fits compact industrial controllers that combine parallel I/O, control state machines, and programmable signal conditioning. Its verified 6,000-LUT capacity provides substantially more logic than a small CPLD, while 190 I/O can support multiple sensors, actuators, counters, and communication transceivers. In a typical control board, the FPGA could implement timing, interlocks, pulse shaping, and interface logic beside a microcontroller. The 1.2 V supply and 256-FBGA package demand careful rail and thermal planning. Before layout, verify the exact I/O standards, configuration scheme, pin assignments, and industrial temperature requirements in the Lattice documentation.
推薦
Parallel Data Acquisition and Signal Conditioning
With 190 I/O and approximately 6,000 LUTs, the LFE2-6E-6F256C can consolidate parallel ADC, counter, timer, and digital sensor interfaces in one programmable-logic device. The FPGA can implement input capture, filtering, calibration, data packing, and a host interface while preserving deterministic timing. Its 256-FBGA package provides many physical balls for high pin-count fan-out, although routing density and signal-integrity margins still require a proper package-aware layout. The verified data does not specify supported voltage standards or maximum I/O rates, so those checks must precede board release.
推薦
Communications and Protocol Bridging
The LFE2-6E-6F256C is suitable for fixed-function protocol conversion, UART or bus bridging, and packet-format handling when parallel interfaces and moderate logic capacity are required. Its verified DSP marking indicates dedicated signal-processing resources, and the 190-I/O count allows several buses and control signals to be consolidated. A practical implementation could use the FPGA for framing, CRC generation, buffering, and timing between two interfaces. The final design must check supported I/O standards, clock domains, configuration pins, and package ball assignments; these details are not present in the supplied snippets.
推薦
Test and Measurement Instrumentation
A 6K-LUT ECP2 FPGA can coordinate timing sequences, pattern generation, capture logic, and instrument-control interfaces in a compact test system. The LFE2-6E-6F256C's 190 I/O is useful when multiple digital channels must be routed between a DUT interface, counters, and a control processor. Its 256-FBGA package also supports dense fan-out compared with leaded programmable logic. Engineering review should include clock jitter, I/O voltage tolerances, configuration startup, thermal behavior, and the exact LFE2-6E-6F256C pin map. The supplied data confirms the package and I/O count but does not establish a particular instrumentation grade.
推薦
Embedded Video and Image Processing
The LFE2-6E-6F256C can serve as a preprocessing FPGA when a design needs programmable pixel timing, thresholding, filtering, or data-format conversion before a host processor receives the result. Its verified 6,000 LUTs and DSP support provide a useful baseline for compact image pipelines, while 190 I/O can accommodate parallel sensors and memory interfaces. The practical limitation is resource and bandwidth availability, which must be calculated for the target image format and frame rate. Because the supplied evidence does not state block RAM, clock limits, or I/O standards, do not commit to a resolution or frame rate without consulting the official ECP2 data.
推薦
Consumer and Embedded Logic Modules
The LFE2-6E-6F256C can add programmable logic, display timing, keypad scanning, motor sequencing, or peripheral arbitration to a larger embedded system. Its 256-FBGA package and 190-I/O count make it appropriate when a controller board needs many deterministic signals without relying on a large software loop. The device can implement boot-time configuration and hardware safety interlocks alongside a microcontroller. Designers should budget PCB area for the BGA escape routing, validate power sequencing for the 1.2 V core, and confirm configuration storage. Compliance and environmental claims are not supplied for this exact MPN and should be verified separately.

主要差異化特點
- High verified I/O density (對比LFE2-6E-6FN256C)
- DSP-capable programmable logic (對比LFE2-6E-6FN256C)
- Explicit 1.2 V core operating point (對比LFE2-6E-6FN256I)
- Same-family sourcing path (對比LFE2-6E-6SE-5FN256C)
設計說明
Treat the 256-FBGA as a package-specific routing problem rather than copying a generic 256-ball land pattern. Confirm the official LFE2-6E-6F256C ball map, power balls, configuration pins, exposed-pad requirements, and escape strategy before placement. The verified sources establish a 256-pin FBGA and 190 I/O, but they do not provide the complete pin assignment; board layout must therefore be based on the manufacturer package drawing.
The verified target supply is 1.2 V, but the supplied snippets do not provide current limits, power consumption, or sequencing requirements. Before designing the power tree, determine the required core and I/O supplies from the official datasheet, check the tolerance and startup order, and estimate dynamic power from the actual clock, I/O, DSP, and memory utilization. Do not infer a regulator rating from the 1.2 V label alone.
Use the device's supported I/O standards and official timing constraints as the basis for edge-rate and termination decisions. The verified data confirms 190 I/O but does not identify voltage standards, slew limits, input thresholds, or maximum toggle rates. Account for BGA return paths, continuous reference planes, length matching where required, and the coupling between the FPGA and external memory or transceiver. Verify the final interface with simulation and measurement rather than relying on the generic FPGA category.
The ECP2 family offers related ordering codes, but a similar MPN does not automatically prove that its ball map, temperature grade, speed grade, configuration interface, or memory resources are interchangeable. For any substitution, compare the exact LFE2-6E-6F256C package drawing, pin table, speed grade, electrical limits, and bitstream constraints. Rebuild and revalidate the design in the Lattice tool flow before treating a related device as a production replacement.
