ATSAML11D16A-YUT

Overview

The ATSAML11D16A-YUT is a 32-bit ARM Cortex-M23 microcontroller from the SAM L11 family, manufactured by Microchip Technology. It integrates 64KB of Flash memory and 16KB of SRAM within a 24-SSOP package. The device operates at a maximum clock frequency of 32MHz and supports a supply voltage range of 1.62V to 3.63V. It features an internal oscillator and includes cryptographic security capabilities. The component is rated for an operating temperature range of -40°C to +85°C.

Feature Summary

• Integrates ARM TrustZone technology for hardware-based security isolation
• Includes dedicated cryptographic engine for secure data processing
• Supports low-power operation modes suitable for battery-constrained applications

Applications

• Secure wearable devices requiring hardware encryption
• IoT sensor nodes with authentication requirements
• Smart home security peripherals

Procurement Notes

Verify the specific suffix 'YUT' corresponds to the 24-SSOP package and tape-and-reel packaging configuration. Confirm that the cryptographic features are enabled in the final silicon revision. Ensure compatibility with development tools supporting the SAM L11 series before procurement.

Selection Notes

Select this part when a balance of moderate code storage and robust security is required. The 24-pin SSOP package offers a compact solution for space-constrained designs. Consider the 32MHz performance limit and available I/O count against application demands compared to higher-density variants in the SAM L11 family.

Part Context

This component belongs to the SAM L11 series, which focuses on ultra-low-power performance combined with enhanced security features. It utilizes the ARM Cortex-M23 core, designed for efficiency and safety-critical applications. The series distinguishes itself by integrating hardware security modules directly into low-power MCUs.

Replacement Considerations

ATSAML11D16A-YFT: Identical electrical specifications and memory size but housed in a different SSOP package variant.
