EFM®32 Tiny Gecko

Silicon Labs' EFM32 Tiny Gecko is ideal for low power applications subject to stringent PCB space and product cost limitations

Image of Silicon Labs' EFM32 Tiny GeckoSilicon Labs' EFM32 Tiny Gecko (TG) microcontrollers offer the energy-efficient performance of the company's bigger Gecko products combined with smaller Flash and RAM combinations and a choice of space-saving QFN20, QFN32, or QFN64 packaging.

Engineered around the energy-efficient ARM® Cortex™-M3 architecture, the 32-bit Gecko products use less than a quarter of the energy needed by alternative 8-, 16-, or 32-bit microcontrollers. Their current consumption is extremely low: in active mode typically 180 µA per MHz executing code from Flash, 900 nA in deep sleep mode, and 20 nA in shut off mode. In application benchmark tests, this low current performance, combined with a wake-up time of under 2 µs, has enabled the EFM32 Gecko microcontrollers to extend battery cell life by a factor of at least four.
