Wonder Gecko MCU enables longer battery life

The EFM32 Wonder Gecko MCU from Energy Micro includes an ARM Cortex-M4 processor that provides a full DSP instruction set and a dedicated floating point unit (FPU). The Wonder Gecko also utilizes the eLL (extreme low leakage) process for ultimate low-power operation in active and sleep modes.

The Wonder Gecko family consists of 60 scalable memory and package configurations with up to 256 KB Flash and 32 KB RAM, and QFN64 to BGA120 options. All options include the autonomous Gecko peripherals and interface options like LESENSE, LETIMER, PRS, USB and TFT/LCD drivers for a complete system on chip solution.

Design tools for planning, coding and design verification are supported by Energy Micro’s free Simplicity Studio suite. To reduce the design time, Simplicity Studio includes the CMSIS-DSP library with over 60 functions in fixed-point and single precision floating-point (32-bit) implementation, and documentation for DSP algorithms such as complex FFT, FIR filters, matrix and vector operations and statistical analysis. All supporting hardware development tools come with a built-in J-Link debugger from SEGGER, so it is only necessary to plug it into your computer’s USB port to get started.

The EFM32 Wonder Gecko microcontrollers cost from USD2.64 in 100k units, and the accompanying starter kit with built in J-Link debugger, the EFM32WG-STK3800, sells from USD79. The products are available from Mouser and Digi-Key as well as franchised distributors.
