ATSAML10E15A-AFT

Overview

The ATSAML10E15A-AFT is a 32-bit microcontroller from the Microchip SAM L10 family, built on the ARM Cortex-M23 core. It features 32KB of in-system programmable flash memory and 8KB of SRAM. The device operates at a maximum frequency of 32MHz with a supply voltage range of 1.62V to 3.63V. It includes an internal oscillator, 25 I/O lines, and supports interfaces such as I2C, SPI, UART/USART, and LINbus. The component is housed in a 32-TQFP package and functions within a temperature range of -40°C to 125°C.

Feature Summary

• Integrates ARM TrustZone technology for hardware-based security isolation
• Includes a Peripheral Touch Controller (PTC) for capacitive touch sensing applications
• Features a CryptoAuthentication module for secure cryptographic operations

Applications

• Secure consumer electronics requiring code protection
• Industrial control systems operating in high-temperature environments
• Battery-powered devices utilizing ultra-low-power modes
• Smart home appliances with touch interface requirements

Procurement Notes

Verify the specific suffix 'AFT' against official Microchip documentation to confirm the 125°C industrial temperature grade and TQFP packaging. Ensure compatibility with development tools supporting the SAM L10 series. Check for recent Product Change Notifications regarding assembly sites or material changes before finalizing procurement.

Selection Notes

Select this model when high-temperature operation up to 125°C is required alongside robust security features. The 32KB flash and 8KB RAM suit moderate complexity firmware. Compare against the ATSAML10E15A-MUT variant if a smaller VQFN package is preferred instead of the TQFP form factor.

Part Context

This component belongs to the SAM L10 family of ultra-low-power microcontrollers. It shares the Cortex-M23 architecture with other members but differs in memory size and package options. The E15 designation typically indicates the 32KB flash configuration within this specific product line.

Replacement Considerations

ATSAML10E15A-MUT offers identical electrical specifications in a 32-VQFN package. ATSAML10E15A-AU provides the same performance in a standard 32-TQFP package without the extended temperature rating.
