ATSAML11E16A-MF

Overview

The ATSAML11E16A-MF is a 32-bit microcontroller from the SAM L11 series, built on the ARM Cortex-M23 core. It features 64KB of Flash memory and 16KB of SRAM. The device operates at a maximum frequency of 32MHz with a supply voltage range of 1.62V to 3.63V. It includes 25 I/O pins, a 12-bit ADC, and supports interfaces such as I2C, SPI, UART, and LINbus. The component is housed in a 32-VQFN package and functions within an industrial temperature range of -40°C to 85°C.

Feature Summary

• Integrates Arm TrustZone technology for hardware-based security isolation
• Optimized for ultra-low power consumption in active and standby modes
• Includes cryptographic accelerators for secure data processing

Applications

• Secure wearable devices requiring low power and encryption
• Industrial IoT sensors with authentication needs
• Smart home security peripherals

Procurement Notes

Verify the suffix 'MF' indicates the tube packaging format, distinct from the 'MUT' reel variant. Confirm the operating temperature grade matches the -40°C to 85°C specification. Ensure design compatibility with the 32-VQFN footprint and pinout. Cross-reference the latest datasheet for any errata or specific assembly guidelines provided by Microchip Technology.

Selection Notes

Select this model when 64KB program storage and 16KB RAM are required alongside hardware security features. The VQFN-32 package suits space-constrained designs. Compare against ATSAML11E16A-MUT if tape-and-reel automation is preferred over tube handling. Ensure the application does not require the extended high-temperature range found in other series variants.

Part Context

This part belongs to the SAM L11 family of ultra-low-power microcontrollers. It shares the Cortex-M23 core and peripheral set with the SAM L10 series but adds integrated security capabilities. The E16 designation typically denotes the 64KB Flash configuration within the L11 lineup.

Replacement Considerations

ATSAML11E16A-MUT is a functional equivalent with identical electrical specifications but utilizes tape-and-reel packaging instead of tubes.
