• Industrial and factory automation systems
• Home automation and security devices
• Mid- and high-tier wearable electronics
• IoT connected devices

Microcontrollers Procurement Notes

Verify the 'I' suffix confirms the -40 °C to +125 °C extended temperature grade and the 'L112' suffix specifies the BGA112 package. Confirm the 'AR' suffix indicates tape and reel packaging. Ensure the feature set code '4' matches requirements for QSPI, SDIO, and LCD support without DC-DC converter integration.

Microcontrollers Selection Notes

Select this variant when extended industrial temperature ratings are required alongside specific connectivity features like Quad-SPI and SDIO. The absence of an integrated DC-DC converter distinguishes it from higher-performance variants within the same family. Verify GPIO count and peripheral availability against system design constraints before finalizing the component choice.

Microcontrollers Part Context

This component belongs to the EFM32 Giant Gecko Series 1 family, designed for energy-sensitive applications requiring high performance. The GG12 series offers up to 1024 kB Flash and 192 kB RAM, targeting complex embedded tasks. It integrates advanced peripherals such as LESENSE and PDM interfaces for sensor data acquisition.

Microcontrollers Replacement Considerations

EFM32GG12B410F1024GL112-A shares identical electrical specifications but operates within the standard commercial temperature range (-40 °C to +85 °C). Other GG12 variants may differ in memory size, package type, or the presence of integrated regulators and specific communication interfaces.
