ATSAML11D14A-YU

Overview

The ATSAML11D14A-YU is a 32-bit microcontroller from the SAM L11 family, featuring an ARM Cortex-M23 core operating at 32MHz. It integrates 16KB of Flash memory and 8KB of SRAM within a 24-SSOP package. The device supports a supply voltage range of 1.62V to 3.63V and operates between -40°C and +85°C. Key peripherals include five 12-bit ADCs, one 10-bit DAC, and communication interfaces such as I2C, SPI, UART/USART, and LINbus.

Feature Summary

• Integrates hardware security features including True Random Number Generator (TRNG) and Advanced Encryption Standard (AES) engine for secure data processing.

Applications

• Secure IoT sensor nodes
• Low-power wearable devices
• Smart home security systems

Procurement Notes

Verify the specific suffix 'YU' corresponds to the 24-SSOP package variant when sourcing. Confirm RoHS compliance status with the supplier. Ensure ESD handling procedures are followed during assembly due to the sensitive nature of the CMOS technology used in this microcontroller series.

Selection Notes

Select this component for designs requiring integrated cryptographic acceleration alongside low-power operation. Compare against the ATSAML11D14A-MUT if surface-mount QFN packaging is preferred over SSOP. Evaluate power consumption requirements against the Cortex-M23 architecture capabilities for battery-operated applications.

Part Context

This part belongs to the Microchip SAM L11 family of Arm Cortex-M23 microcontrollers. These devices are designed for ultra-low-power applications with enhanced security features. The family shares common peripheral sets but varies in memory size and package options.

Replacement Considerations

ATSAML11D14A-MUT offers identical electrical specifications but utilizes a 24-VQFN package instead of SSOP. Verify pin compatibility and thermal performance differences before substitution.
