MPN: LFE2-50E-5F672C ✓ ActiveLFE2-50E-5F672C Overview
An FPGA is a programmable semiconductor whose digital logic, I/O, and embedded resources can be configured after manufacture. Within the product hierarchy, the LFE2-50E-5F672C is a field-programmable gate array, an LatticeECP2 FPGA, a reconfigurable digital logic IC, and a semiconductor intended for embedded systems. Its large 672-ball package supports a high pin count and extensive user I/O, while its 48,000 LUT capacity supports parallel digital logic and DSP-oriented designs.
The verified product information identifies 48,000 LUTs, 500 I/O, a 1.2 V supply, a -5 speed grade, and a 672-pin FBGA package. Cross-reference data lists the device as a 50,000-cell FPGA operating at 357 MHz and describes its package as a 27 mm by 27 mm lead-free FBGA-672. These specifications make it relevant to industrial control, communications, instrumentation, and embedded processing systems requiring extensive programmable logic.
The LFE2-50E-5F672C belongs to the LatticeECP2 family and uses 90 nm CMOS fabrication technology. Its 396,288-bit configuration-memory value is shown for the closely related 50K ECP2 listing, while the target listing itself is presented as a 48K-LUT device. The ECP2 architecture combines programmable logic with DSP resources, allowing designers to implement control logic, data pipelines, serial interfaces, and protocol handling in one programmable device.
Typical uses include industrial automation controllers, communications interface modules, test and measurement equipment, embedded video and control systems, and general-purpose system-on-chip prototypes. The 500 available I/O are particularly useful when a design requires multiple parallel buses, mixed logic interfaces, or high pin-count connectivity. Its 357 MHz listed performance gives the design a concrete clock target, subject to the device's documented configuration and timing conditions.
The most important design check is the difference between pin compatibility and complete application equivalence. The verified cross-reference data explicitly describes LFE2-50E-5FN672C as a complete replacement, while other ECP2 ordering codes can differ in speed grade, temperature suffix, or package marking. Engineers should compare the exact Lattice ordering guide, power requirements, configuration scheme, and system timing before approving a substitution.
This page consolidates verified supplier specifications, same-package ECP2 alternatives, parameter comparisons, pricing availability status, and practical design guidance. It distinguishes explicitly documented replacement candidates from ordering variants whose exact electrical, temperature, or package details require manufacturer confirmation.

Typical Applications
LFE2-50E-5F672C is suitable for 6 applications: Industrial Automation Controllers, Communications Interface Modules, Test and Measurement Equipment, Embedded System-on-Chip Designs, Data Acquisition and Signal Conditioning, Programmable Logic Development.
Industrial Automation Controllers
The LFE2-50E-5F672C fits industrial automation control when a machine or process controller needs extensive parallel logic and programmable timing. Its 48,000 LUTs and 500 I/Os provide substantial capacity for sequencing logic, motor-control interfaces, interlocks, and digital sensor conditioning, while the listed 357 MHz performance supports clocked control and datapath functions. The 1.2 V core supply also places it in the low-voltage programmable-logic domain used by modern FPGA systems. Because the verified data does not state a numerical operating-temperature range, industrial qualification should not be inferred from the family name alone. Confirm the exact temperature suffix, I/O voltage tolerances, power sequencing, and industrial qualification details before deploying the FPGA in factory-floor equipment.
Recommended
Communications Interface Modules
The LFE2-50E-5F672C is appropriate for communications equipment requiring configurable serial framing, buffering, and parallel data conversion. Its 500 I/Os allow a compact module to connect multiple buses or high-density digital interfaces without relying on several fixed-function glue devices. The 48,000-LUT capacity can support protocol state machines, test logic, and data-path pipelines, while the 357 MHz listed frequency provides a useful performance target for synchronous designs. For industrial RS-485, CAN, or Ethernet-adjacent subsystems, companion transceivers must be matched to the actual voltage, isolation, and signaling requirements. Before layout release, verify pin assignments, supported I/O standards, clocking resources, and configuration pins in the current 672-pin FBGA documentation.
Recommended
Test and Measurement Equipment
The LFE2-50E-5F672C can serve as the programmable control and acquisition engine in test and measurement equipment because it combines 48,000 LUTs, a 357 MHz listed maximum frequency, DSP capability, and 500 user I/Os in one device. These resources allow engineers to implement timing generation, pattern control, acquisition logic, and instrument-specific protocol handling in parallel. The high I/O count is valuable for tester fixtures and parallel instrument interfaces, while DSP resources support filtering or waveform-processing blocks. The 1.2 V core supply simplifies integration with contemporary mixed-signal components, but external analog front ends still require their own power and reference design. Timing closure, input thresholds, output standards, and calibration paths must be verified against the actual instrument architecture.
Recommended
Embedded System-on-Chip Designs
The LFE2-50E-5F672C is well suited to embedded system-on-chip prototypes that consolidate control logic, peripheral bridges, and fixed datapath functions into one programmable device. Its 48,000 LUTs and 500 I/Os allow multiple subsystem interfaces to coexist, while the ECP2 family's DSP resources can accelerate filtering, correlation, or waveform shaping. The device is implemented in 90 nm CMOS and operates from a 1.2 V core, matching the architecture of many contemporary embedded control systems. A successful design still needs a deliberate partition between FPGA fabric and external processors, plus careful configuration-memory, clock, and power planning. Use the 672-ball FBGA footprint for fanout-constrained systems, but confirm every ball location and power-ground assignment from manufacturer documentation.
Recommended
Data Acquisition and Signal Conditioning
The LFE2-50E-5F672C fits data-acquisition subsystems that need flexible digital signal conditioning between an analog front end and a host processor. Its DSP resources can implement filtering, decimation, and data alignment, while 48,000 LUTs provide parallel channel multiplexing and control logic. The 500 available I/Os are useful when several converters, status signals, and synchronization lines must be coordinated. The listed 357 MHz performance can support demanding synchronous pipelines, although actual throughput depends on the selected clock, fabric architecture, and timing constraints. Analog precision remains the responsibility of the converter and amplifier stages rather than the FPGA. Confirm converter interface voltage, clock-edge compatibility, input timing, and output latency to prevent digital integration from limiting the acquisition system.
Recommended
Programmable Logic Development
The LFE2-50E-5F672C can support FPGA logic-development, education, and prototype platforms where a large pin count and substantial LUT capacity are valuable. Its 48,000 LUTs allow students or engineers to implement multiple bus bridges, counters, memory controllers, DSP examples, and interface experiments, while the 500 I/Os reduce the need for expansion logic during early prototyping. The 357 MHz listed performance provides a clear target for timing exercises, and the 1.2 V core is compatible with modern FPGA board power systems. A development board should still include suitable configuration memory or another supported boot path, clock generation, decoupling, and I/O conditioning. Because no complete verified pin table was provided, prototype designers should rely on the current manufacturer pinout before assigning board connectors.

Key Differentiators
- Documented direct replacement with the same ECP2 package class (vs LFE2-50E-5FN672C)
- Higher speed-grade option in the same 672-ball ECP2 family (vs LFE2-50E-6FN672C)
- Identical verified core resource profile for the SE-family comparison part (vs LFE2-50SE-5F672C)
Design Notes
Do not treat every 672-pin ECP2 ordering code as automatically interchangeable. The verified cross-reference explicitly describes LFE2-50E-5FN672C as a complete replacement, but speed suffixes, SE-family identifiers, and C or I terminal suffixes may represent different operating or commercial configurations. Compare the exact pinout, core and I/O voltage requirements, supported configuration pins, temperature range, and timing tables for the specific suffix before releasing a substitute to manufacturing.
Plan the FBGA-672 layout around the manufacturer's exact ball map, power rails, ground assignments, configuration pins, and decoupling recommendations. The verified package is square and approximately 27 mm by 27 mm, with 672 terminals. Use short return paths for supply connections and place decoupling capacitors close to the relevant supply and ground balls. Because no complete verified pin table was provided, the mechanical footprint and electrical netlist must be checked against current Lattice documentation rather than inferred from another ECP2 device.
Budget the 1.2 V core rail and every required I/O supply separately, accounting for static current, configurable logic activity, and I/O loading. The supplied data confirms a 1.2 V core but does not provide current limits, regulator recommendations, startup sequencing, or power-down behavior. Estimated current and thermal values must not be inferred from the 357 MHz frequency; obtain the ECP2 power table and use worst-case utilization assumptions when selecting regulators and supply capacity.
Assign clocks, high-speed buses, and sensitive configuration interfaces according to the documented ECP2 I/O standards and routing constraints. The LFE2-50E-5F672C exposes 500 I/O, so an indiscriminate pin assignment can create simultaneous-switching-noise and routing-congestion problems even when the nominal 357 MHz figure is acceptable. Keep clocks on dedicated clock-capable pins, match trace lengths where required by the interface, and validate the final board with the actual FPGA timing constraints and I/O implementation.
Compliance Information
The verified FindIC comparison describes the LFE2-50E-5F672C as lead free. No explicit RoHS, REACH, AEC-Q100, halogen-free, or conflict-minerals statements were present in the supplied data, so those fields remain unknown.
