Compact housings with extremely low power consumption


A “busy bee” – this is the starter kit with which we are offering you free entry to the
high-speed and ultra-low power world of the EFM8™ series from SILICON LABS.

The “Busy Bee” starter kit contains a fully fledged hardware debugger, the tool chain “Simplicity Studio” and a free licence for the Keil compiler.
Everything that makes a developer's heart beat faster.

Compact housings (starting at 1.78 x 1.65 mm), an extremely low power consumption of 50 nA (ultra sleep) and a short wakeup time of 2µs and 150 µA/MHz are what set the EFM8™ series apart.
Ideal for various applications in the IoT sector. 

The EFM8™ series is based on the 8-bit CPU core CIP-51, which is compatible with the process architecture 8051. The number of clock cycles per command has been reduced from 12 to 1-2, and the clock frequency increased to 72 MHz.
