ATSAML11D15A-MFTKPH

Overview

The ATSAML11D15A-MFTKPH is a 32-bit microcontroller from the SAM L11 family, featuring an ARM Cortex-M23 core operating at 32MHz. It integrates 32KB of Flash memory and 8KB of SRAM within a 32-VQFN package. The device supports a supply voltage range of 1.62V to 3.63V and operates between -40°C and +85°C. Key peripherals include five 12-bit ADC channels, one 10-bit DAC, and communication interfaces such as I2C, SPI, UART/USART, and LINbus.

Feature Summary

• Integrates ARM TrustZone-M technology for hardware-based security isolation
• Includes pre-configured Trustonic Root of Trust keys for secure boot
• Features enhanced Positive Temperature Coefficient (PTC) sensors
• Supports low-power operation with multiple sleep modes

Applications

• Secure IoT sensor nodes requiring hardware root of trust
• Industrial control systems utilizing PTC temperature sensing
• Battery-powered devices needing ultra-low power management
• Smart home appliances with secure communication requirements

Procurement Notes

Verify the specific suffix KPH indicates the inclusion of Trustonic Root of Trust keys and Kinibi-M software support. Confirm the MFT designation corresponds to the 32-VQFN package and industrial temperature range. Ensure compatibility with Secure Thingz or Trustonic deployment architectures if key provisioning is required for the target application.

Selection Notes

Select this model when hardware-enforced security via TrustZone and pre-loaded root keys are mandatory. Compare against standard SAML11 variants if key provisioning flexibility is needed instead of fixed factory keys. Consider the 32-VQFN package constraints for PCB layout and thermal dissipation in dense designs.

Part Context

This component belongs to the Microchip SAM L11 series, designed for applications demanding high security and low power consumption. It builds upon the Cortex-M23 architecture with added TrustZone capabilities and integrated PTC sensors, distinguishing it from the non-security-focused SAM L10 series.

Replacement Considerations

ATSAML11E15A-UUTKPH offers similar security features but in a WLCSP-32 package with 25 I/Os. Standard ATSAML11D15A-MU provides equivalent memory and core specs without the pre-configured Trustonic keys.
