Overview
The ATSAML11E15A-MUTKPH is a 32-bit 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 integrates a 12-bit ADC with 10 channels and a 10-bit DAC. Connectivity includes I2C, LINbus, SPI, and USART interfaces. It operates within a voltage range of 1.62 V to 3.63 V and supports an industrial temperature range from -40 °C to +85 °C. The component is housed in a WLCSP-32 package.
Feature Summary
- Integrates Arm TrustZone for Armv8-M technology to provide hardware-based security isolation between secure and non-secure execution environments.
- Includes dedicated cryptographic acceleration capabilities for efficient data encryption and decryption operations.
- Features a Peripheral Touch Controller (PTC) designed for capacitive touch sensing applications.
Applications
- Battery-powered IoT sensor nodes requiring low power consumption
- Secure boot subsystems utilizing hardware trust zones
- Industrial control devices with capacitive user interfaces
Procurement Notes
Verify the specific suffix configuration against official Microchip documentation to ensure compatibility with required packaging and tape-and-reel specifications. Confirm that the selected variant meets all environmental and electrical requirements for the target application before finalizing procurement orders.
Selection Notes
Select this model when both ultra-low power performance and hardware-enforced security are required. The inclusion of TrustZone and crypto acceleration distinguishes it from standard L10 series variants. Ensure the design accommodates the WLCSP-32 package constraints and utilizes the internal oscillator or external clock sources as specified in the datasheet.
Part Context
This component belongs to the SAM L11 family of microcontrollers, which are optimized for ultra-low-power applications. The family shares the Cortex-M23 architecture but differentiates through integrated security features like TrustZone and enhanced peripheral sets compared to the base SAM L10 series.
Replacement Considerations
Cross-reference with ATSAML11E15A-AUKPH for TQFP packaging alternatives. Verify functional equivalence regarding security features and pinout compatibility before substituting packages.
