ATSAML10E15A-UUT

Overview

The ATSAML10E15A-UUT is an ARM microcontroller from the Microchip ATSAML10 series, featuring a Cortex-M23 core. It integrates 32 kB of Flash program memory and 8 kB of SRAM data RAM. The device operates at a maximum clock frequency of 32 MHz and supports surface-mount installation in a WLCSP-32 package. It functions within a temperature range of -40°C to +85°C.

Feature Summary

• Integrates TrustZone-based security architecture for code isolation
• Includes Peripheral Touch Controller (PTC) for capacitive sensing applications
• Features multiple communication interfaces including SERCOM modules
• Provides analog capabilities with ADC, DAC, operational amplifiers, and comparators

Applications

• Battery-powered wearable devices requiring low power consumption
• Smart home sensors utilizing touch interface controls
• Industrial monitoring nodes with analog signal processing needs
• Secure IoT endpoints leveraging hardware-based security features

Procurement Notes

Verify the specific suffix UUT corresponds to the WLCSP-32 wafer-level chip-scale package configuration. Confirm that the ordering quantity aligns with manufacturer reel specifications. Ensure compatibility with existing PCB footprint designs for this compact form factor before finalizing procurement orders.

Selection Notes

Select this component when a small footprint is critical due to the WLCSP-32 packaging. Choose this model over TQFP variants if board space is limited. Consider the integrated PTC and analog peripherals if sensor interfacing is required without external components. Verify voltage supply requirements match the system design constraints.

Part Context

This part belongs to the ATSAML10 family of ultra-low-power microcontrollers based on the ARM Cortex-M23 architecture. The family emphasizes energy efficiency and security for embedded applications. The UUT suffix specifically denotes the wafer-level chip-scale package variant, distinguishing it from leaded or QFN alternatives within the same functional series.

Replacement Considerations

ATSAML10E15A-AU offers identical core functionality but utilizes a 32-TQFP package instead of WLCSP. ATSAML10E15A-MU provides the same electrical characteristics in a VQFN-32 package. These alternatives maintain software compatibility while differing only in physical mounting style.
