ATSAML11E15A-MFTKPH

Overview

The ATSAML11E15A-MFTKPH is a 32-bit ARM Cortex-M23 microcontroller from the SAM L11 family, featuring 32KB of flash memory and 8KB of SRAM. It operates at a maximum frequency of 32MHz with a supply voltage range of 1.62V to 3.63V. The device includes a 10-channel 12-bit ADC, a 1-channel 10-bit DAC, and supports interfaces such as I2C, LIN, RS-485, SPI, and USART. It utilizes a WLCSP-32 package and is rated for an operating temperature range of -40°C to +85°C.

Feature Summary

• Pre-configured with Trustonic Root of Trust keys for hardware-based security
• Integrated Crypto engine and TrustZone-M technology for secure execution environments
• Enhanced Positive Temperature Coefficient (PTC) sensor support
• Low-power architecture with multiple sleep modes and flexible clock distribution

Applications

• Secure IoT edge devices requiring hardware root of trust
• Smart energy metering applications
• Industrial sensors with encrypted data transmission
• Consumer electronics needing secure key provisioning

Procurement Notes

Verify the specific suffix KPH indicates pre-provisioned Trustonic keys. Confirm package type is WLCSP-32. Check RoHS compliance status. Ensure development tools like Kinibi-M SDK are available for integration. Validate lead times as factory special orders may vary.

Selection Notes

Select this variant over standard SAML11 models when pre-provisioned hardware roots of trust are required. Compare pin counts and peripheral sets against ATSAML11D series if lower memory suffices. Consider the WLCSP-32 package constraints for PCB layout versus VQFN options.

Part Context

Part of the Microchip SAM L11 family of ultra-low power MCUs based on the ARM Cortex-M23 core. This series emphasizes security features including TrustZone-M and integrated cryptographic engines. The E15A designation typically denotes specific memory configurations within the family.

Replacement Considerations

ATSAML11E15A-MU: Standard version without pre-provisioned Trustonic keys. ATSAML11D15A-MUT: Lower pin count variant with different package. Verify functional equivalence regarding security features and peripheral availability before substitution.
