EFM32WG Datasheet, PDF (2/834 Pages) List of Unclassifed Manufacturers – The EFM32WG Wonder Gecko is the ideal choice for demanding 8-, 16-, and 32-bit energy sensitive applications.

...the world's most energy friendly microcontrollers
1 Energy Friendly Microcontrollers
1.1 Typical Applications
The EFM32WG Wonder Gecko is the ideal choice for demanding 8-, 16-, and 32-bit energy sensitive
applications. These devices are developed to minimize the energy consumption by lowering both the
power and the active time, over all phases of MCU operation. This unique combination of ultra low energy
consumption and the performance of the 32-bit ARM Cortex-M4 processor, help designers get more out
of the available energy in a variety of applications.
Ultra low energy EFM32WG microcontrollers are perfect for:
• Gas metering
• Energy metering
• Water metering
• Smart metering
• Alarm and security systems
• Health and fitness applications
• Industrial and home automation

1.2 EFM32WG Development
Because EFM32WG use the Cortex-M4 CPU, embedded designers benefit from the largest
development ecosystem in the industry, the ARM ecosystem. The development suite spans the whole
design process and includes powerful debug tools, and some of the world’s top brand compilers.
Libraries with documentation and user examples shorten time from idea to market.
The range of EFM32WG devices ensure easy migration and feature upgrade possibilities.
