ATSAML11D15A-YFT

Overview

The ATSAML11D15A-YFT is a 32-bit microcontroller from the Microchip SAM L11 family, built on the ARM Cortex-M23 core. It operates at a maximum frequency of 32MHz and includes 32KB of Flash memory, 8KB of SRAM, and 2KB of EEPROM. The device features five 12-bit ADC channels and one 10-bit DAC. It supports I2C, LINbus, SPI, and UART/USART interfaces. Operating voltage ranges from 1.62V to 3.63V, with a temperature range of -40°C to 85°C. It is housed in a 24-SSOP package.

Feature Summary

• Integrates hardware security features including TrustZone and cryptographic accelerators for secure boot and data protection.
• Includes an enhanced Peripheral Touch Controller (PTC) supporting capacitive touch sensing applications.
• Provides multiple communication peripherals such as DMA, PWM, and watchdog timers for efficient system management.

Applications

• Secure consumer electronics requiring trusted execution environments
• Battery-powered IoT devices utilizing low-power modes
• Industrial control systems needing robust peripheral connectivity

Procurement Notes

Verify the specific suffix against official Microchip documentation to confirm package type and temperature grade. Ensure compatibility with development tools like MPLAB X IDE. Check for recent Product Change Notices regarding assembly or fabrication sites. Confirm RoHS compliance status through current datasheets before integration into production designs.

Selection Notes

Select this component when a balance of security, touch capability, and moderate performance is required. Compare storage capacities with other SAM L11 variants if larger memory is needed. Consider the SSOP package constraints for PCB layout compared to QFN options. Evaluate power consumption requirements against the device's active and sleep modes.

Part Context

This part belongs to the SAM L11 series of ultra-low-power microcontrollers. It shares architectural similarities with the ATSAML11D15A-MUT but differs in packaging. The series targets applications demanding high security and touch interface integration within a compact form factor.

Replacement Considerations

ATSAML11D15A-MUT offers identical electrical specifications but utilizes a VQFN-24 package instead of SSOP. Verify pinout compatibility and thermal dissipation requirements when substituting packages. No functional differences exist between these variants within the same memory configuration.
