Overview
The ATSAML11E16A-AUTKPH is a Microchip Technology microcontroller based on the ARM Cortex-M23 core, operating at a maximum frequency of 32 MHz. It features 64 kB of Flash program memory and 16 kB of SRAM data RAM. The device supports a supply voltage range from 1.62 V to 3.63 V and operates within a temperature range of -40°C to +85°C. It includes integrated cryptographic hardware for security applications.
Feature Summary
- Integrates Arm TrustZone technology for hardware-based security isolation between secure and non-secure execution environments.
- Includes dedicated cryptographic accelerators supporting AES, SHA, and RSA operations for secure key management and data protection.
- Features ultra-low power consumption modes optimized for battery-operated IoT devices and sensor nodes.
Applications
- Secure boot implementations requiring trusted execution environments
- Battery-powered IoT sensor nodes with encryption requirements
- Industrial control systems needing hardware-level security isolation
Procurement Notes
Verify the specific suffix 'AUTKPH' against official Microchip documentation to confirm package type and tape/reel specifications. Ensure compatibility with existing PCB footprints for the WLCSP or similar small outline packages associated with this variant. Confirm moisture sensitivity level handling procedures during assembly.
Selection Notes
Select this component when both high security (TrustZone/Crypto) and low power are required in a compact form factor. Compare pin counts and memory sizes against other ATSAML11 variants like the E15 or E14 series to ensure sufficient I/O and storage for the target application constraints.
Part Context
This part belongs to the ATSAML11 family, designed specifically for secure, low-power embedded applications. It shares the Cortex-M23 architecture with other members but offers distinct memory configurations and package options tailored for different integration densities and cost targets within the same ecosystem.
Replacement Considerations
Consult Microchip's official cross-reference tools for verified substitutes. Potential alternatives within the same family include ATSAML11E16A-MUT or ATSAML11E15A-UUTKPH, depending on whether package changes or memory adjustments are acceptable for the design.
