Overview
The ATSAML11E15A-MUT is a 32-bit microcontroller from the Microchip SAM L11 series, featuring an ARM Cortex-M23 core operating at 32MHz. It integrates 32KB of Flash memory and 8KB of SRAM within a 32-WLCSP package. The device supports a supply voltage range of 1.62V to 3.63V and includes 25 I/O pins. Peripheral interfaces include I2C, SPI, UART/USART, and LINbus. Analog capabilities consist of five 12-bit ADC channels and one 10-bit DAC. It operates within a temperature range of -40°C to 85°C.
Feature Summary
- Integrates hardware security features including TrustZone and cryptographic accelerators for secure data processing.
- Includes an enhanced Peripheral Touch Controller (PTC) supporting capacitive touch sensing applications.
- Provides versatile serial communication interfaces such as SPI, I2C, UART, and LINbus for system connectivity.
Applications
- Secure IoT sensor nodes requiring hardware-based encryption
- Battery-powered wearable devices utilizing capacitive touch interfaces
- Industrial control systems with LINbus communication requirements
Procurement Notes
Verify the specific package variant, as the suffix 'MUT' denotes a WLCSP form factor which may differ from other pinouts in the same family. Confirm RoHS compliance status and moisture sensitivity level prior to assembly planning. Cross-reference the latest errata sheet for any known silicon revisions or operational clarifications relevant to this specific batch.
Selection Notes
Select this component when a compact WLCSP footprint is required alongside dedicated security features like TrustZone. It is suitable for designs needing moderate I/O counts with integrated touch sensing capabilities. Compare against the ATSAML10 series if cryptographic features are not mandatory, or consider the ATSAML11D series for alternative package options.
Part Context
This part belongs to the SAM L11 family of ultra-low-power microcontrollers based on the ARM Cortex-M23 architecture. The family emphasizes energy efficiency combined with robust security implementations. The ATSAML11E15A-MUT specifically targets applications demanding secure boot and encrypted storage in a minimal spatial envelope.
Replacement Considerations
ATSAML11E15A-MU serves as a direct pin-compatible alternative in a different package type. For non-security variants, the ATSAML10E15A series offers similar performance without cryptographic hardware. Verify peripheral mapping compatibility before substituting.
