ATSAML10D15A-YUT

Overview

The ATSAML10D15A-YUT is a 32-bit microcontroller from the Microchip SAM L10 series, featuring an ARM Cortex-M23 core operating at 32MHz. It integrates 32KB of Flash memory, 8KB of SRAM, and 2KB of EEPROM. The device includes five 12-bit ADC channels and one 10-bit DAC. Connectivity options comprise I²C, LINbus, SPI, and UART/USART interfaces. It supports 17 general-purpose I/O pins and operates within a voltage range of 1.62V to 3.63V across a temperature range of -40°C to 85°C. The component is housed in a 24-SSOP package.

Feature Summary

• Integrates ARM TrustZone technology for hardware-based security isolation
• Includes Crypto authentication peripheral for secure boot and data protection
• Features enhanced Peripheral Touch Controller (PTC) for capacitive sensing applications

Applications

• Secure IoT sensor nodes requiring hardware trust zones
• Battery-powered devices utilizing ultra-low-power modes
• Industrial control systems with LINbus communication requirements
• Consumer electronics needing capacitive touch interface support

Procurement Notes

Verify the specific suffix YUT confirms the 24-SSOP package variant during procurement. Ensure compatibility with design tools supporting the SAM L10 family architecture. Confirm RoHS compliance status matches project environmental regulations. Validate that the internal oscillator configuration meets system timing accuracy requirements without external crystals.

Selection Notes

Select this model when 32KB program storage and 17 I/O lines are sufficient for the application logic. Choose over larger variants if board space constraints favor the compact SSOP footprint. Consider this part for designs requiring integrated crypto and PTC features without additional discrete components. Verify power supply stability within the 1.62V to 3.63V range for reliable operation.

Part Context

This component belongs to the Microchip SAM L10 family of ultra-low-power MCUs based on the ARM Cortex-M23 core. The family emphasizes energy efficiency combined with hardware security features like TrustZone and cryptographic accelerators. The D15A designation typically indicates the specific memory configuration and I/O count within this series.

Replacement Considerations

ATSAML10D15A-MU offers identical functionality in a VQFN-24 package. ATSAML10E15A-AU provides increased I/O count in a TQFP-32 package. Substitution requires verifying pinout compatibility and ensuring the alternative package fits the PCB layout constraints.
