ATSAML11D16A-YF

Overview

The ATSAML11D16A-YF 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 features 64KB of Flash memory and 16KB of SRAM. The device includes an AES-128 hardware security engine for cryptographic operations. It supports I2C, SPI, UART/USART, and LINbus interfaces. Power supply ranges from 1.62V to 3.63V. It offers five 12-bit ADC channels and one 10-bit DAC. The component is housed in a 24-SSOP package and functions within a temperature range of -40°C to +125°C.

Feature Summary

• Integrated hardware security engine supporting AES-128 encryption algorithms
• Low-power ARM Cortex-M23 processor core optimized for energy efficiency
• Comprehensive analog peripheral set including multiple 12-bit ADCs and a 10-bit DAC

Applications

• Secure consumer electronics requiring data protection
• Industrial control systems utilizing LINbus communication
• Battery-powered IoT devices needing low power consumption

Procurement Notes

Verify the specific suffix 'YF' corresponds to the 24-SSOP package and extended temperature range when sourcing. Confirm RoHS compliance status with the supplier. Ensure ESD handling procedures are followed during assembly due to moisture sensitivity classification. Cross-reference pinouts with official datasheets to prevent integration errors.

Selection Notes

Select this model for applications requiring integrated hardware security alongside standard connectivity options. Compare against other SAM L11 variants based on required Flash size and package constraints. Consider the operating temperature range if deployed in harsh environments. Evaluate power consumption profiles against system battery life requirements.

Part Context

This component belongs to the SAM L11 series of microcontrollers designed for low-power applications. It shares architectural similarities with other members of the family but differs in memory capacity and package type. The series emphasizes security features and efficient processing for embedded control tasks.

Replacement Considerations

ATSAML11D16A-MUT serves as a functional alternative with identical specifications but utilizes a VQFN package instead of SSOP. Verify footprint compatibility before substitution.
