Microchip ATSAML11E15A-MF

Industry’s first and lowest power Arm® Cortex®-M23 featuring chip-level security and ARM® TrustZone® Technology, consuming less than 25uA/MHz in active mode and less than 100 nA in sleep mode. It features secure key storage, chip-level tamper resistance, crypto accelerators, secure boot, secure bootloader, enhanced peripheral touch controller, advanced analog, ISO7816 smart card interface, event system and SleepWalking peripherals.

SAM L11 achieved EEMBC Certified ULPMark Core Profile score of 410 & Peripheral Profile score of 167

SAML11-KPH variants (Example part#: ATSAML11E15A-MUKPH) are pre-provisioned with Trustonic Root of Trust key and are supported by Kinibi-M Software Development Kit.

SAML11 variants(Example part#: ATSAML11E15A-MU) have the option to be securely key provisioned using Secure Thingz Secure Deploy™ Architecture.

Supported by MPLAB X IDE and MPLAB Harmony.
