Target Device Atmel SAML11
Hardware Crypto Yes
Status In Developement

This board supports the Microchip ATSAML11 microcontroller.

Power Supply

The core of the SAML11 chip runs from a 1.2v supply. This is supplied through the CW308T 1.2v regulator. The I/O busses are supplied with 3.3v.

Security Features

The SAML11 platform integrates many advanced security features including:

  • Up to four tamper pins for static and dynamic intrusion detections
  • Silent flash access for side channel attack resistance
  • Data scrambling with user-defined keys for both Flash and RAM
  • A True Random Number Generator

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


The SAML10/11 family implements a serial bootloader. Usage of this bootloader is not detailed in the data sheet, for usage information see Microchip Application note AN2699[2].

Serial Wire Debug (SWD) is also supported for programming and debugging applications.
