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]
Programming¶
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].
