This board supports the Microchip ATSAML11 microcontroller.
|Target Architecture||Arm Cortex-M23|
|Programming||Serial Bootloader, SWD|
Available from Mouser.
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.
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
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. 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.
