ATSAML11E15A-AUT

Overview

The ATSAML11E15A-AUT is a 32-bit microcontroller from the SAM L11 family, featuring an ARM Cortex-M23 core operating at up to 32MHz. It integrates 32KB of Flash memory and 8KB of SRAM within a 32-pin TQFP package. The device supports a supply voltage range of 1.62V to 3.63V and includes cryptographic security features with TrustZone technology. Peripheral interfaces include I2C, SPI, UART/USART, and LINbus, alongside multiple analog-to-digital converters.

Feature Summary

• Integrates ARM TrustZone for hardware-based security isolation
• Includes dedicated cryptographic acceleration capabilities
• Features low-power operation modes including standby and sleep

Applications

• Secure IoT sensor nodes
• Smart home devices requiring data encryption
• Industrial control systems with secure communication needs

Procurement Notes

Verify the specific suffix 'AUT' against official Microchip documentation to confirm tape-and-reel packaging status, as datasheets often list 'AU' for trays. Ensure the component meets AEC-Q100 automotive qualification requirements if applicable to the target design environment.

Selection Notes

Select this model when both high-level security via TrustZone and moderate storage capacity are required. Compare against the ATSAML10 series if cryptographic features are unnecessary, or consider the ATSAML11D variant for reduced pin counts in space-constrained applications.

Part Context

This component belongs to the SAM L11 family, which extends the low-power SAM L10 architecture with enhanced security features. The family targets applications demanding robust protection against physical and software attacks while maintaining energy efficiency.

Replacement Considerations

ATSAML11E15A-AU serves as the tray-packaged equivalent. For non-security variants, the ATSAML10E15A-AU offers similar performance without TrustZone.
