# CW308T-ATSAML11 This board supports the Microchip ATSAML11 microcontroller. ![](Images/saml11-picture.png) ## Specifications | Feature | Notes/Range | |---------|----------| | Target Device | ATSAML11E16A | | Target Architecture | Arm Cortex-M23 | | Vcc | 1.2V | | Programming | Serial Bootloader, SWD | | Hardware Crypto | Accelerator | | Availability | Standalone | | Status | Released | | Shunt | 22Ω | Available from [Mouser](https://www.mouser.com/ProductDetail/NewAE/NAE-CW308T-ATSAML11?qs=PzGy0jfpSMuVApvEE0Yklw%3D%3D). --- ## 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. --- ## Schematic and Layout ![](Images/saml11-sch.png) [^1]: [^2]:
