Target Device Silicon Labs EFM32TG11
Hardware Crypto Yes
Status In Developement

This board supports the Silicon Labs EFM32 Tiny Gecko 11 microcontroller. The chip mounted on the target board is the EMF32TG11B3.

Power Supply

The core of the Tiny Gecko chip runs from a 1.2v supply. This is supplied and filtered through the CW308T. The I/O buses are supplied with 3.3v.

Security Features

The Tiny Gecko family of microcontrollers implements many security features including:

  • Hardware implementations of AES-128/256, SHA-224/256
  • Hardware CRC engine
  • Access control for peripherals

For a full list of security features see the product family data sheet[1]


A serial bootloader is implemented on the Tiny Gecko series of chips. Details for the use of this feature are described in Silicon Labs application note AN0042[2].
