Overview
The ATSAML11E15A-AU is a 32-bit microcontroller from the SAM L11 family, built on the ARM Cortex-M23 core. It features 32KB of flash memory and 8KB of SRAM. The device operates at speeds up to 32MHz with a supply voltage range of 1.62V to 3.63V. It includes 25 programmable I/O lines and supports interfaces such as I2C, SPI, UART/USART, and LINbus. The unit is housed in a 32-TQFP package and functions within a temperature range of -40°C to +85°C.
Feature Summary
- Integrates ARM TrustZone technology for hardware-based security isolation
- Includes cryptographic acceleration capabilities for secure data processing
- Features an event system allowing peripheral-to-peripheral communication without CPU intervention
Applications
- Secure IoT sensor nodes requiring hardware encryption
- Low-power industrial control systems with LINbus connectivity
- Battery-operated devices utilizing standby modes with SRAM retention
Procurement Notes
Verify the specific suffix against official Microchip documentation to confirm pinout and package dimensions. Ensure compatibility with required security configurations, as SAML11 models support distinct TrustZone implementations compared to the SAML10 series. Confirm operating temperature ratings match the target environment specifications before integration.
Selection Notes
Select this model when ARM TrustZone security is mandatory, distinguishing it from the non-TrustZone SAML10 variant. Choose based on the requirement for 32KB flash and 25 I/O pins in a TQFP-32 package. Consider the 1.62V minimum supply voltage for low-power battery applications requiring stable operation under varying load conditions.
Part Context
This component belongs to the SAM L11 family of ultra-low-power MCUs. Unlike the SAML10 series, the SAML11 family incorporates ARM TrustZone for enhanced security isolation. The family shares the Cortex-M23 core architecture but differs in security features and memory configurations across various pin counts and packages.
Replacement Considerations
ATSAML10E15A-AU lacks TrustZone security features. ATSAML11E15A-MUT offers the same functionality in a VQFN-24 package. Verify that any substitute maintains the required security level and interface availability.
