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

Since it’s a Cortex-M23 core, it’s also got Arm TrustZone-M.

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


Programming#

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]. This bootloader doesn’t have a driver in ChipWhisperer, but one could be added.

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