ATSAML11E15A-MFKPH

Overview

The ATSAML11E15A-MFKPH is a Microchip Technology microcontroller based on the ARM Cortex-M23 core, operating at a maximum frequency of 32 MHz. It features 32 kB of Flash memory and 8 kB of SRAM. The device includes integrated cryptographic hardware for security applications. It supports multiple communication interfaces including I2C, SPI, and USART. The unit operates within a voltage range of 1.62 V to 3.63 V and functions across a temperature range of -40°C to +85°C.

Feature Summary

• Integrated TrustZone-M technology for secure code execution
• Hardware-accelerated cryptographic engine support
• Low-power operation with configurable sleep modes

Applications

• Secure IoT sensor nodes
• Cryptographic key storage devices
• Industrial control systems requiring authentication

Procurement Notes

Verify the specific suffix MFKPH against official Microchip documentation to confirm package type and pre-provisioned security keys. Ensure compatibility with required development tools such as Kinibi-M SDK. Confirm RoHS compliance status via current datasheets before finalizing procurement specifications.

Selection Notes

Select this component when ARMv8-M TrustZone isolation is required alongside standard SAM L11 peripherals. Compare pin counts and memory sizes against ATSAML11D variants if fewer I/O lines are sufficient. Validate that the 32-bit architecture meets processing requirements for intended firmware complexity.

Part Context

This part belongs to the SAM L11 family of microcontrollers designed for security-focused applications. It shares the Cortex-M23 core with the SAM L10 series but adds enhanced memory protection units and TrustZone capabilities. The family targets low-power embedded systems needing robust data protection.

Replacement Considerations

ATSAML11E15A-MUKPH is a documented alternative variant within the same family offering similar core specifications.
