The EZR32LG family of Wireless MCUs deliver a high performance, low energy wireless solution inte-
grated into a small form factor package. By combining a high performance sub-GHz RF transceiver
with an energy efficient 32-bit MCU, the family provides designers the ultimate in flexibility with a fam-
ily of pin-compatible devices that scale from 64/128/256 kB of flash and support Silicon Labs EZRadio
or EZRadioPRO transceivers. The ultra-low power operating modes and fast wake-up times of the
Silicon Labs energy friendly 32-bit MCUs, combined with the low transmit and receive power con-
sumption of the sub-GHz radio, result in a solution optimized for battery powered applications.
To develop and/or evaluate the EZR32Leopard Gecko the EZR32LG Radio Board can
be connected to the Wireless Starter Kit Mainboard to get access to display, buttons and
additional features from Expansion Boards.
