ATSAML11E15A-MUKPH

Overview

The ATSAML11E15A-MUKPH is a 32-bit ARM Cortex-M23 microcontroller from the SAM L11 family, manufactured by Microchip Technology. It features 64KB of flash memory and 16KB of SRAM, operating at a maximum frequency of 32MHz. The device supports a supply voltage range of 1.62V to 3.63V and includes integrated cryptographic security with TrustZone for Armv8-M. It utilizes a VQFN-32 package (5x5mm) and operates within a temperature range of -40°C to +85°C.

Feature Summary

• Integrated hardware security engine supporting TrustZone for Armv8-M architecture
• Pre-configured Secure Thingz Secure Deploy architecture for key management
• Supports Kinibi-M software development kit for secure application deployment

Applications

• Secure IoT sensor nodes requiring hardware-based authentication
• Low-power wearable devices with strict security requirements
• Industrial control systems needing protected firmware storage

Procurement Notes

Verify the specific suffix 'KPH' indicates the pre-configured Secure Thingz and Kinibi-M support during procurement. Confirm package availability matches the VQFN-32 specification. Ensure design tools align with the required secure deployment workflows. Check current RoHS compliance status against latest manufacturer notices.

Selection Notes

Select this variant when hardware-level security and pre-provisioned keys are mandatory. Compare with standard ATSAML11E15A-MU if security configuration is handled externally. Consider pin count and thermal performance for the VQFN-32 footprint. Validate software compatibility with Kinibi-M SDK before finalizing the design.

Part Context

This component belongs to the SAM L11 series of ultra-low-power microcontrollers. It shares the core Cortex-M23 architecture with other SAM L11 variants but distinguishes itself through factory-installed security credentials. The KPH suffix denotes specific secure provisioning not found in standard commercial units.

Replacement Considerations

Standard ATSAML11E15A-MU lacks pre-configured security keys. Verify if external secure element integration can substitute for the built-in TrustZone features. Ensure any replacement supports the same VQFN-32 package dimensions.
