LFE2-20E-5F484C - 21K LUT FPGA, 331 I/O | Lattice
MPN： LFE2-20E-5F484C ✗ 停產LFE2-20E-5F484C 概覽
An FPGA is a programmable semiconductor whose lookup tables, registers, interconnect, and dedicated blocks can be configured after manufacture. The LFE2-20E-5F484C belongs to the ECP2 FPGA family and provides a hardware platform for parallel logic, state machines, interfaces, control logic, and DSP pipelines. Its 331 I/O make the package especially useful when the design requires substantial external connectivity.
The supplied distributor information identifies the device as an ECP2 FPGA with 21K LUTs, 331 I/O, DSP support, 1.2 V operation, and a -5 speed designation. The package is identified as 484-BBGA. Detailed timing, memory, configuration, electrical, and temperature data are not present in the supplied source excerpts, so those values are not asserted here. The design should be checked against the manufacturer datasheet before layout, power budgeting, or production qualification.
A -5 FPGA speed designation indicates the manufacturer’s speed-grade family, but the operating-temperature grade and timing margins are not stated in the verified excerpts. The 1.2 V core supply is the confirmed supply value, while external I/O supply requirements, configuration voltage, and power consumption require the full manufacturer documentation. The 484-BBGA package requires a PCB footprint and thermal design appropriate for a large fine-pitch BGA.
Typical design uses include industrial automation, communications equipment, video and image processing, embedded control, and general-purpose programmable logic. The large I/O count can support external memory, parallel buses, sensor interfaces, transceiver connections, and control peripherals. DSP capability can reduce external processing hardware when the design uses fixed-point or parallel signal-processing functions implemented within the FPGA.
For a new PCB, preserve the exact Lattice package pinout and ball assignment, define clean power and ground planes, and validate high-speed routing with the complete timing and pinout documentation. Do not treat distributor snippets as a substitute for the manufacturer datasheet. This page consolidates the verified distributor identity, package, density, I/O, voltage, and sourcing information while explicitly separating unknown technical details.
The practical advantage of this part is its combination of moderate FPGA logic density, extensive I/O, DSP support, and a 1.2 V core architecture. It is more suitable than a small logic device when a design needs substantial parallel connectivity, while the -5 grade should be selected only after confirming timing requirements against the complete Lattice documentation.

主要差異化特點
- High verified I/O availability for parallel systems (對比LFE2-20E-5F484I)
- DSP capability is explicitly identified for the target (對比LFEC20E-5F484C)
- Confirmed core supply and speed designation (對比LFE2M20SE-5F484C)
設計說明
Start the layout by obtaining the manufacturer’s exact 484-BBGA ball map, land pattern, and escape-routing guidance. Reserve continuous power and ground planes, place decoupling close to the relevant supply balls, and route high-speed signals with controlled impedance. Because the verified data confirms the package and ball count but not the full pinout or stack-up requirements, do not finalize the PCB footprint from distributor summaries alone.
Build the power tree around the verified 1.2 V core requirement, then confirm every auxiliary and I/O supply from the complete Lattice datasheet. Separate noisy digital activity from sensitive analog or external interface sections where practical, and validate power sequencing against configuration requirements. The supplied excerpts do not state current consumption, tolerance, startup behavior, or decoupling values, so those values must not be guessed.
A 484-BBGA design requires disciplined escape routing and signal-integrity planning. Keep clock and configuration paths short, avoid routing high-speed signals through power-plane splits, and use the manufacturer’s recommended ball assignments and I/O standards. Establish a timing-closure plan around the -5 speed designation and the actual clock targets. The verified excerpts do not provide maximum frequency or I/O timing values, so validation must use the complete family documentation.
Do not substitute a related Lattice MPN solely because it has a similar 484-BBGA package. Confirm logic resources, I/O count, voltage rails, speed grade, temperature grade, configuration method, memory resources, and qualification. The cross-reference results name several candidates, but search snippets are not proof of drop-in equivalence. Verify the exact ordering table and pin map before releasing a replacement or respin.
合規資訊
The supplied verified data does not state RoHS, REACH, lead-free, halogen-free, conflict-mineral, or automotive qualification status for LFE2-20E-5F484C. AEC-Q100 is recorded as not applicable because the verified data does not identify this device as an automotive-qualified part.
