Overview
The ATSAML11E16A-UUT is a 32-bit microcontroller from the SAM L11 series, featuring an ARM Cortex-M23 core operating at up to 32 MHz. It integrates 64 KB of flash memory and 16 KB of SRAM within a 32-pin VQFN package. The device supports a supply voltage range of 1.62 V to 3.63 V and operates between -40°C and +85°C. Key peripherals include ten 12-bit ADC channels, one 10-bit DAC, and standard communication interfaces such as I2C, SPI, UART/USART, and LINbus.
Feature Summary
- Supports Arm TrustZone for Armv8-M architecture for hardware-based security isolation
- Integrates low-power peripherals including DMA, PWM, and watchdog timer
- Features internal oscillator with high-accuracy calibration capabilities
Applications
- Battery-powered IoT sensor nodes requiring ultra-low power consumption
- Secure boot subsystems utilizing hardware trust zones
- Industrial control terminals with LINbus connectivity requirements
Procurement Notes
Verify the suffix 'UUT' corresponds to the specific tape-and-reel packaging configuration required for your assembly line. Confirm that the 32-VQFN footprint matches your PCB design guidelines. Ensure compatibility with the 1.62V to 3.63V supply voltage range in your target application circuitry before finalizing procurement.
Selection Notes
Select this component when both high-level security features via TrustZone and ultra-low power operation are critical. It is suitable for applications needing moderate code storage (64KB) and data RAM (16KB). Consider alternative pin counts or memory sizes if the 32-pin VQFN form factor or specific peripheral count does not align with system constraints.
Part Context
This part belongs to the Microchip SAM L11 family, designed specifically for secure, battery-operated embedded systems. The series emphasizes energy efficiency combined with robust cryptographic capabilities, making it distinct from general-purpose MCUs by integrating hardware security modules directly into the Cortex-M23 architecture.
Replacement Considerations
Consult official cross-reference lists for compatible devices within the SAM L11 family. Verify pinout and register compatibility before substituting with other variants.
