ATSAML10D16A-YU

Overview

The ATSAML10D16A-YU is a 32-bit microcontroller from the Microchip SAM L10 series, featuring an ARM Cortex-M23 core. It integrates 64KB of Flash memory and 16KB of SRAM within a 24-SSOP package. The device operates at a maximum clock speed of 32MHz with a supply voltage range of 1.62V to 3.63V. It supports I2C, LINbus, SPI, and UART/USART interfaces, includes five 12-bit ADC channels and one 10-bit DAC, and functions within a temperature range of -40°C to 85°C.

Feature Summary

• Integrates ARM Cortex-M23 processor core for efficient 32-bit processing
• Includes hardware security features such as TrustZone and cryptographic accelerators
• Provides versatile communication capabilities via multiple serial peripheral interfaces
• Features enhanced Peripheral Touch Controller for capacitive touch sensing applications

Applications

• Battery-powered IoT sensor nodes
• Smart home control devices
• Industrial monitoring systems
• Wearable electronic devices

Procurement Notes

Verify the specific suffix 'YU' against official Microchip documentation to confirm the 24-SSOP package type and commercial temperature rating. Ensure compatibility with existing board layouts designed for SSOP footprints. Cross-reference part numbers with current datasheets to avoid confusion with similar VQFN variants like the ATSAML10D16A-MUT.

Selection Notes

Select this component when a 24-pin SSOP package is required instead of QFN options. It offers higher memory capacity than the 16KB or 32KB variants in the same family. Consider the internal oscillator accuracy and available GPIO count relative to system interface requirements before finalizing the design.

Part Context

This unit belongs to the SAM L10 family of ultra-low-power microcontrollers. These devices are optimized for battery-operated applications requiring secure code execution and touch sensing. The family shares common architectural features while varying in memory size and package options to suit different form factors.

Replacement Considerations

Direct substitutes include other SAM L10 variants with identical pinouts but different memory sizes, such as ATSAML10D15A-YU (32KB Flash) or ATSAML10D14A-YU (16KB Flash). Verify that the lower memory variants meet application storage needs.
