ATSAML11D16A-MF

Overview

The ATSAML11D16A-MF is a 32-bit ARM Cortex-M23 microcontroller from the Microchip SAM L11 family, housed in a 24-pin VQFN package. It integrates 64 kB of Flash memory and 16 kB of SRAM. The device operates with a maximum clock frequency of 32 MHz and supports an input/output count of 17 I/O lines. Power supply ranges from 900 mV to 1.2 V for low-power modes and 1.62 V to 3.63 V for standard operation. It features a 12-bit ADC resolution and includes hardware cryptographic acceleration. The operating temperature range extends from -40°C to +85°C or +125°C depending on specific variant configurations.

Feature Summary

• Integrated hardware cryptographic engine for secure data processing
• Ultra-low power architecture based on ARM Cortex-M23 core
• Supports multiple communication interfaces including SPI, I2C, and UART

Applications

• Secure IoT sensor nodes
• Low-power wearable devices

Procurement Notes

Verify the suffix 'MF' indicates tube packaging and extended temperature range capabilities compared to other variants. Confirm RoHS compliance status through official Microchip documentation before integration. Ensure design compatibility with the 24-VQFN footprint and thermal requirements for the specified operating environment.

Selection Notes

Select this model when hardware-based security is required alongside ultra-low power consumption. Compare against the ATSAML11D16A-MU if tube packaging is preferred over tray options. Consider the 125°C temperature rating if operating in harsh industrial environments. Verify pinout compatibility with existing board layouts designed for the SAM L11 series.

Part Context

This component belongs to the Microchip SAM L11 series of ultra-low power microcontrollers. It shares the Cortex-M23 core architecture with other members like the ATSAML11D16A-MUT but differs in packaging and temperature specifications. The series emphasizes energy efficiency and integrated security features for embedded applications.

Replacement Considerations

ATSAML11D16A-MUT offers similar functionality in tape-and-reel packaging. ATSAML11D16A-MU provides comparable specs in tube packaging with potentially different temperature ratings. Verify electrical characteristics and pin compatibility before substitution.
