ATSAML11E15A-AFKPH

Overview

The ATSAML11E15A-AFKPH is a 32-bit ARM Cortex-M23 microcontroller from the Microchip SAM L11 family. It features 32 kB of Flash memory and 8 kB of SRAM, operating at a maximum clock frequency of 32 MHz. The device supports a supply voltage range of 1.62 V to 3.63 V and includes integrated cryptographic security modules. It offers 25 general-purpose I/O pins and is housed in a 32-ball WLCSP package.

Feature Summary

• Integrates hardware-based cryptographic acceleration for secure data processing
• Supports TrustZone-M technology for system-level security isolation
• Includes programmable threshold controller for analog signal monitoring

Applications

• Secure IoT sensor nodes
• Low-power wearable devices
• Smart home security peripherals

Procurement Notes

Verify the specific suffix AFKPH against official datasheets to confirm package type and temperature grade. Ensure compatibility with existing board layouts due to the WLCSP form factor. Check for recent PCN updates regarding assembly sites or material changes before finalizing procurement plans.

Selection Notes

Select this component when small footprint and high security are required. Compare with ATSAML10 series if cryptographic features are unnecessary. Verify pinout compatibility with alternative packages like TQFP if redesigning for different manufacturing constraints.

Part Context

This MCU belongs to the SAM L11 series, designed for ultra-low power applications requiring robust security. It shares architectural similarities with the SAM L10 but adds dedicated crypto engines. The series targets battery-operated devices needing long life and data protection.

Replacement Considerations

ATSAML11E15A-UUTKPH: Same core specifications but in WLCSP-32 package; verify pin mapping differences.
