ATSAML11E16A-MUT

Overview

The ATSAML11E16A-MUT is a 32-bit microcontroller from the SAM L11 series, featuring an ARM Cortex-M23 core operating at 32MHz. It integrates 64KB of flash memory and 16KB of SRAM within a 32-VQFN package. The device supports a supply voltage range of 1.62V to 3.63V and includes 25 I/O pins. Peripheral interfaces include I2C, LINbus, SPI, and UART/USART. Data conversion capabilities consist of ten 12-bit ADC channels and one 10-bit DAC. Additional features encompass DMA, PWM, watchdog timer, power-on reset, and brown-out detection.

Feature Summary

• Supports Arm TrustZone for Armv8-M architecture for hardware-based security isolation
• Integrates cryptographic acceleration for secure data processing
• Features ultra-low power consumption modes including standby current as low as 200nA
• Includes internal oscillator with no external crystal required for basic operation

Applications

• Battery-powered IoT sensor nodes requiring extended operational life
• Industrial control systems needing secure boot and trusted execution environments
• Smart home devices utilizing Zigbee or Thread protocols
• Wearable electronics demanding minimal power draw in active and sleep states

Procurement Notes

Verify the specific suffix 'MUT' corresponds to the tape and reel packaging format when ordering. Confirm that the design accommodates the 32-VQFN footprint dimensions and thermal requirements. Ensure compatibility with the 1.62V to 3.63V supply voltage range for all connected peripherals. Check for any recent Product Change Notifications regarding assembly sites or materials before finalizing procurement plans.

Selection Notes

Select this component when both high-level security features via TrustZone and ultra-low power performance are critical. It is suitable for applications requiring moderate code storage (64KB) and RAM (16KB). Consider alternative pin counts if more or fewer general-purpose I/O lines are needed. Evaluate the need for external oscillators if precise timing accuracy beyond the internal RC oscillator is required.

Part Context

This part belongs to the Microchip SAM L11 family, designed specifically for low-power, secure embedded applications. The series utilizes the ARM Cortex-M23 core, which provides efficient code density and enhanced security features compared to previous generations. The ATSAML11E16A variant offers a balanced mix of memory and connectivity options within a compact package.

Replacement Considerations

Consult official cross-reference lists for direct replacements. Variants such as ATSAML11D14A-MUT offer similar functionality with reduced memory and I/O counts. Higher capacity options within the same package may exist but require verification of pin compatibility and software migration efforts.
