ATSAML10D15A-MU

Overview

The ATSAML10D15A-MU is an ARM Cortex-M23 microcontroller from the SAM L10 family, housed in a 24-VQFN package. It features 32 KB of Flash memory and 8 KB of SRAM. The device operates at a maximum clock frequency of 32 MHz with a supply voltage range of 1.62V to 3.63V. It includes 17 I/O lines, five 12-bit ADC channels, one 10-bit DAC, and supports interfaces such as I2C, SPI, UART/USART, and LINbus.

Feature Summary

• Integrates ARM Cortex-M23 core with TrustZone for secure execution environments
• Includes hardware cryptographic acceleration for data protection
• Features programmable threshold controller for analog signal monitoring

Applications

• Secure IoT sensor nodes
• Smart home devices requiring low power consumption
• Industrial control systems with security requirements

Procurement Notes

Verify the specific suffix against official Microchip documentation to confirm package type and temperature grade. Ensure compatibility with existing PCB footprints for the VQFN-24 form factor. Confirm RoHS compliance status through current datasheets before finalizing procurement specifications.

Selection Notes

Select this component when a balance of security features and low power consumption is required. The 32 MHz speed suits applications needing moderate processing capability without excessive energy drain. Compare pin counts and peripheral sets against similar models like the ATSAML11 series if additional crypto capabilities are needed.

Part Context

This part belongs to the SAM L10 family of ultra-low-power MCUs designed for battery-operated devices. It shares architectural similarities with other M23-based chips but offers specific memory configurations and peripheral sets tailored for cost-sensitive, security-conscious embedded applications.

Replacement Considerations

ATSAML10D15A-MUT serves as the tape-and-reel equivalent for automated assembly processes.
