EFM32 Pearl Gecko Family
EFM32PG1 Data Sheet
The EFM32 Pearl Gecko MCUs are the world’s most energy-
friendly microcontrollers.
EFM32PG1 features a powerful 32-bit ARM^® Cortex^®-M4 and a wide selection of periph-
erals, including a unique cryptographic hardware engine supporting AES, ECC, and
SHA. These features, combined with ultra-low current active mode and short wake-up
time from energy-saving modes, make EFM32PG1 microcontrollers well suited for any
battery-powered application, as well as other systems requiring high performance and
low-energy consumption.
Example applications:
• IoT devices and sensors
• Health and fitness
• Smart accessories
• Home automation and security
• Industrial and factory automation
