EFM32™ Giant Gecko 32-bit Microcontroller

Our EFM32™ Giant Gecko ARM® Cortex®-M3-based 32-bit microcontrollers (MCUs) provide flash memory configurations up to 1024 kB, 128 kB of RAM, and CPU speeds up to 48 MHz, making them ideal for energy-sensitive applications with high memory and connectivity requirements. Our Giant Gecko low-power MCUs are available in packages down to 7x7 mm, as well as full wafer options, and feature autonomous, low-energy peripherals, including AES encryption, pulse counter, low-energy UARTs, a low-energy sensor interface, and on-chip operational amplifiers.

The USB connectivity option is USB 2.0 compliant at full speed (12 Mbps), integrating 2 kB endpoint buffers and handling up to 14 endpoints. Our Giant Gecko MCUs provide support for USB host, device and on-the-go configurations, as well as bootloader over USB.

Sleep current with RTC as low as
1.1 μA
Active current as low as
