ATSAML11E16A-MUKPH

Overview

The ATSAML11E16A-MUKPH is a 32-bit ARM Cortex-M23 microcontroller from the SAM L11 series, manufactured by Microchip Technology. It features 64KB of Flash memory and 16KB of SRAM within a 32-pin WLCSP package. The device operates at a maximum clock frequency of 32MHz with a supply voltage range of 1.62V to 3.63V. It includes integrated cryptographic hardware, TrustZone-M security, and multiple communication interfaces including SPI, I2C, UART, and LINbus.

Feature Summary

• Integrates Arm TrustZone for Armv8-M technology to provide hardware-based security isolation between secure and non-secure execution environments.
• Includes dedicated cryptographic accelerators for efficient handling of encryption and authentication protocols.
• Supports flexible clock distribution architectures optimized for low-power operation across various system states.

Applications

• Secure boot subsystems requiring trusted execution environments
• Battery-powered IoT nodes with strict power consumption constraints
• Industrial sensor terminals needing data integrity protection

Procurement Notes

Verify the specific suffix 'KPH' indicates pre-configured Trustonic Root of Trust keys and Kinibi-M software support as documented for this variant. Confirm package type is WLCSP-32 and ensure EDA models match the specific pinout. Check RoHS compliance status and moisture sensitivity level before integration into manufacturing processes.

Selection Notes

Select this component when both high-level security features and ultra-low power performance are required in a minimal footprint. Compare against standard SMT packages if board space allows, but choose WLCSP for size-constrained designs. Ensure development tools support the specific key provisioning architecture associated with the KPH suffix.

Part Context

This part belongs to the SAM L11 family, which combines Cortex-M23 processing with advanced security features. It is designed for applications demanding both computational efficiency and robust data protection. The KPH suffix distinguishes it from standard variants by including pre-provisioned security keys.

Replacement Considerations

Standard ATSAML11E16A-MU variants lack the pre-configured Trustonic keys. Verify if custom key provisioning can replace the factory-set configuration. Other SAM L11 devices may differ in memory size or package type.
