Overview
The ATSAML11E15A-AF is a 32-bit microcontroller from the Microchip SAM L11 family, built on the ARM Cortex-M23 core. It features 32KB of Flash memory and 8KB of SRAM. The device operates at a maximum frequency of 32MHz with a supply voltage range of 1.62V to 3.63V. It includes an internal oscillator, five 12-bit ADC channels, one 10-bit DAC, and supports interfaces such as I2C, LINbus, SPI, and UART/USART. The component is housed in a 32-TQFP package and functions within a temperature range of -40°C to +85°C.
Feature Summary
- Integrates ARM TrustZone-M technology for hardware-based security isolation.
- Includes a Peripheral Touch Controller (PTC) for capacitive touch sensing applications.
- Features a CryptoCell cryptographic accelerator for secure data processing.
- Supports low-power operation modes suitable for battery-powered devices.
Applications
- Secure consumer electronics requiring code protection
- Battery-operated IoT sensor nodes
- Smart home automation controllers
- Industrial control systems with security requirements
Procurement Notes
Verify the specific suffix 'AF' against the official datasheet to confirm the TQFP-32 package and industrial temperature grade. Ensure compatibility with development tools supporting the SAM L11 series. Confirm RoHS compliance status through current manufacturer documentation before integration into production designs.
Selection Notes
Select this model when a balance of moderate memory capacity and robust security features is required. The TQFP-32 package offers easier manual handling compared to QFN options. Consider the SAM L11 family errata for known silicon revisions prior to finalizing the design implementation.
Part Context
This component belongs to the SAM L11 family of ultra-low-power microcontrollers designed for security-sensitive applications. It shares architectural similarities with the SAM L10 series but adds advanced security peripherals like the CryptoCell and PTC. The family targets applications needing secure boot and encrypted storage capabilities.
Replacement Considerations
ATSAML11D15A-MUT: Different package (VQFN vs TQFP) and pin count. ATSAML11E15A-UUTKPH: Different package (WLCSP). Verify pinout compatibility and thermal performance when substituting.
