ATSAML11D16A-YFT

Overview

The ATSAML11D16A-YFT is a 32-bit ARM Cortex-M23 microcontroller from the SAM L11 family, manufactured by Microchip Technology. It integrates 64 KB of Flash memory and 16 KB of SRAM within a 24-lead SSOP package. The device operates at a maximum clock frequency of 32 MHz and supports an extended industrial temperature range of -40°C to +125°C. Key features include hardware cryptographic acceleration for secure applications and standard connectivity interfaces such as SPI, I2C, and UART.

Feature Summary

• Hardware-accelerated cryptographic engine for secure data processing
• Ultra-low-power ARM Cortex-M23 core architecture
• Extended temperature operation up to 125°C
• Integrated non-volatile memory with SRAM

Applications

• Secure IoT sensor nodes
• Industrial control systems requiring high temperature tolerance
• Smart metering devices
• Access control hardware

Procurement Notes

Verify the specific suffix 'YFT' corresponds to the SSOP-24 package and tape-and-reel packaging configuration. Confirm the extended temperature grade (+125°C) matches application requirements. Check RoHS compliance status and ensure the ordering part number aligns with current Microchip datasheet specifications before procurement.

Selection Notes

Select this component when both secure cryptographic capabilities and extended temperature operation are required in a compact SSOP package. Compare against the ATSAML11E16A series if a QFN package or different pinout is preferred. Ensure system voltage requirements fall within the specified 1.62V to 3.63V range for reliable operation.

Part Context

This part belongs to the SAM L11 family of ultra-low-power microcontrollers based on the ARM Cortex-M23 core. The family emphasizes security and energy efficiency for embedded applications. The 'D' variant typically denotes specific peripheral configurations or package types within the broader SAM L11 lineup, distinguishing it from other memory or package variants.

Replacement Considerations

ATSAML11E16A-MUT offers similar memory and core specifications but utilizes a 32-VQFN package instead of SSOP-24. Verify pin compatibility and thermal performance differences when considering alternative packages within the same memory capacity family.
