Microcontrollers Procurement Notes

Verify the specific suffix 'G' against official datasheets to confirm feature set variations. Check current lifecycle status as some variants in this series are marked obsolete. Confirm moisture sensitivity level and reflow soldering profiles prior to assembly. Ensure the 112-pin BGA footprint matches the design layout exactly.

Microcontrollers Selection Notes

Select this model when 128 kB of program storage and 32 kB of RAM are required within a compact 112-pin BGA form factor. It is suitable for designs needing USB capability without sacrificing GPIO count. Compare against other LG series parts if higher memory or different pin counts are needed.

Microcontrollers Part Context

This component belongs to the EFM32 Leopard Gecko series, designed for energy-sensitive applications. It shares the ARM Cortex-M3 architecture with other Gecko variants but offers specific memory and peripheral configurations tailored for mid-range performance needs.

Microcontrollers Replacement Considerations

EFM32LG390F128G-F-BGA112R is a reel-packaged variant of the same silicon. Other LG series devices may serve as functional substitutes if memory and pin compatibility allow.
