Define the required function
The ECP5-5G branch adds higher-speed serial connectivity within the ECP5 architecture.
Use the requirements below to decide which specification limits your design. A family name alone is not a purchasing specification.
Lattice Semiconductor / FPGA FAMILY
ECP5-5G FPGAs
The ECP5-5G family combines LUT4 fabric, embedded memory, DSP resources and serial transceivers. Compare package channels and consult the electrical tables for protocol and operating conditions.

Selection note
Serial channel count alone does not establish protocol support or usable data rate. The reviewed ordering table lists -8 speed-grade options; these are not cross-vendor speed rankings.

SELECTION CONTEXT
Working with ECP5-5G
Check the integration boundary
Choose the complete device and ordering code before checking package pinout, power, electrical limits and operating grade. Keep family maxima separate from a selected device or package.
Open the manufacturer reference ↗Family selection checkpoints
- Verify package-specific serial lanes and electrical limits.
- Check the exact ordering table and speed grade.

PRACTICAL QUESTIONS
ECP5-5G selection questions
How do I select a model within ECP5-5G?
Start with the documented product scope: The ECP5-5G branch adds higher-speed serial connectivity within the ECP5 architecture. Then compare the device-specific facts below with your required resources and interfaces. Open each model for its evidence and ordering constraints.
Is a base-device name enough to place an order?
A base-device identifier identifies the silicon or model, but may omit package, speed, temperature, qualification and packing options. Use the manufacturer ordering table to establish the complete code. Reference examples do not establish stock or an approved replacement.
Can the listed devices use the same PCB or development tools?
A shared family or manufacturer does not establish pin compatibility. Compare pinout, supply and I/O-bank voltages, configuration, timing, tool support and thermal limits before changing a board.
What should I include for sourcing or PCBA review?
Provide the exact part or board revision, quantity, delivery requirement, operating environment and traceability needs. For assembly, identify BOM readiness, PCB stack-up, programming access and the inspection or functional-test scope.
