ATSAML11E16A-MUTKPH

Overview

The ATSAML11E16A-MUTKPH is a 32-bit microcontroller from the Microchip SAM L11 series, built on the ARM Cortex-M23 core. It features 64KB of in-system programmable Flash memory and 16KB of SRAM. The device operates at a maximum clock frequency of 32MHz with a supply voltage range of 1.62V to 3.63V. It includes an internal oscillator, 25 general-purpose I/Os, and supports interfaces such as I2C, SPI, UART/USART, and LINbus. The component is housed in a 32-VQFN (5x5) package and is rated for operation between -40°C and +85°C.

Feature Summary

• Integrates Arm TrustZone technology for hardware-based security isolation between secure and non-secure execution environments.
• Includes dedicated cryptographic accelerators to support secure boot and data encryption operations.
• Optimized for ultra-low power consumption across active and standby modes to extend battery life in portable devices.

Applications

• Battery-powered IoT sensor nodes requiring long-term energy efficiency
• Secure embedded systems utilizing trusted execution environments
• Industrial control terminals with safety-critical firmware requirements

Procurement Notes

Verify the specific suffix KPH against official datasheets to confirm package marking and tape-and-reel specifications. Ensure compatibility with existing PCB footprints for the 32-VQFN form factor. Cross-reference moisture sensitivity levels and reflow soldering profiles during assembly planning. Confirm that the ordered variant matches the required pinout and thermal characteristics for the target application environment.

Selection Notes

Select this component when both high-level security features and low power consumption are critical. The inclusion of TrustZone and crypto accelerators distinguishes it from standard Cortex-M23 variants. Consider the 64KB Flash capacity relative to application code size. Evaluate the 32MHz performance limit against processing requirements. Verify that the VQFN package suits the available board space and thermal management strategy.

Part Context

This part belongs to the SAM L11 family, designed for applications demanding security and power efficiency. It shares the Cortex-M23 architecture with other members but offers specific memory and peripheral configurations. The series emphasizes ease of migration within the ecosystem while providing robust protection mechanisms for sensitive data and firmware integrity.

Replacement Considerations

Consult official substitution guides for compatible parts within the SAM L11 series. Verify pin-to-pin compatibility and software register mapping before replacing. Ensure equivalent security features and memory sizes are maintained in any alternative selection.
