ATSAML11E16A-AUKPH

Overview

The ATSAML11E16A-AUKPH is a Microchip Technology microcontroller from the SAM L11 series, built on an ARM Cortex-M23 core. It features 64 kB of Flash memory and 16 kB of SRAM. The device operates with a maximum clock frequency of 32 MHz and supports a supply voltage range of 1.62 V to 3.63 V. It includes a 12-bit ADC with 10 channels and provides 25 I/O pins. The component is housed in a 32-VQFN (5x5) package and functions within a temperature range of -40°C to +85°C.

Feature Summary

• Integrates Arm TrustZone for Armv8-M architecture to provide hardware-based security isolation between secure and non-secure execution environments.
• Delivers ultra-low power performance with optimized dynamic current consumption during active operation and minimal standby current draw.
• Supports secure boot processes via internal ROM bootloader capabilities for verifying firmware integrity before execution.

Applications

• Battery-powered IoT sensor nodes requiring extended operational life
• Industrial devices needing secure data acquisition and processing
• Wearable electronics demanding compact form factors and low energy usage

Procurement Notes

Verify the specific suffix AUKPH against official Microchip documentation to confirm pinout compatibility and package dimensions. Ensure that the selected variant matches the required thermal characteristics and moisture sensitivity level for your assembly process. Cross-reference the datasheet revision to validate all electrical specifications prior to finalizing procurement orders.

Selection Notes

Select this component when a balance of moderate code storage capacity and robust hardware security is required. The Cortex-M23 core offers efficient Thumb-2 instruction execution suitable for complex control algorithms. Consider the 32-VQFN package constraints regarding PCB space and thermal dissipation requirements compared to larger TQFP alternatives.

Part Context

This part belongs to the SAM L11 family of ultra-low-power microcontrollers designed for security-conscious embedded applications. It shares architectural similarities with the SAM L10 but offers enhanced memory configurations and advanced cryptographic peripherals. The family targets markets where power efficiency and data protection are critical design drivers.

Replacement Considerations

ATSAML11E16A-MUT serves as a functional equivalent within the same series, offering identical core specifications but utilizing a VQFN package variant. Verify pin-to-pin compatibility and software configuration settings when transitioning between these package types.
