Overview
The ATSAML11E16A-MFT is a 32-bit microcontroller from the SAM L11 series, manufactured by Microchip Technology. It features an ARM Cortex-M23 core operating at a maximum frequency of 32 MHz. The device integrates 64 KB of Flash memory and 16 KB of SRAM. It includes 10 channels of 12-bit ADC and one 10-bit DAC. The unit supports I2C, LINbus, SPI, and UART/USART interfaces with 25 available I/O lines. It operates within a voltage range of 1.62 V to 3.63 V and functions between -40°C and 85°C in a 32-VQFN package.
Feature Summary
- Integrates Arm TrustZone for Armv8-M architecture to provide hardware-based security isolation between secure and non-secure execution environments.
- Delivers ultra-low power performance with dynamic operation as low as 34 µA/MHz and standby current down to 200 nA.
- Includes built-in ROM bootloader supporting secure boot verification from internal or external flash sources.
Applications
- Battery-powered IoT sensor nodes requiring extended operational life
- Industrial communication terminals utilizing LINbus or serial protocols
- Secure embedded systems requiring trusted execution environments
Procurement Notes
Verify the specific suffix 'MFT' against official Microchip documentation to confirm package type and tape/reel specifications. Ensure compatibility with standard surface-mount assembly processes. Confirm moisture sensitivity level handling requirements prior to PCB fabrication. Cross-reference the exact part number with the manufacturer's current production status to ensure availability.
Selection Notes
Select this component when a balance of moderate code storage capacity and robust security features is required. The 64 KB Flash accommodates complex firmware while maintaining low power consumption. Ideal for applications needing hardware-enforced security boundaries without excessive peripheral complexity. Consider thermal management capabilities within the specified operating temperature range during design integration.
Part Context
This MCU belongs to the SAM L11 family, designed specifically for cost-sensitive, battery-operated devices that demand high security. It shares architectural similarities with other Cortex-M23 based MCUs but distinguishes itself through optimized power management and integrated TrustZone support. The family targets smart metering, wearable electronics, and industrial control applications.
Replacement Considerations
Consult Microchip datasheets for direct pin-compatible alternatives within the SAM L11 series. Verify memory size and peripheral availability in substitute models. Ensure security feature parity if TrustZone implementation is critical to the system design.
