ATSAML21E17B-AUT

Overview

The ATSAML21E17B-AUT is an ultra-low-power microcontroller from the SAM L21 series, featuring a 32-bit ARM Cortex-M0+ processor operating at up to 48MHz. It integrates 128KB of in-system self-programmable Flash memory and 16KB of main SRAM. The device supports a supply voltage range of 1.62V to 3.63V and operates within a temperature range of -40°C to +85°C. It is housed in a 32-pin TQFP package with matte tin plating.

Feature Summary

Ultra-low-power architecture with SleepWalking capabilities for peripheral-driven wake-up
Integrated full-speed USB 2.0 interface supporting both host and device functions
Advanced analog peripherals including a 12-bit ADC, dual DACs, and operational amplifiers
Configurable Custom Logic (CCL) for flexible peripheral interconnection

Applications

Battery-powered wearable devices requiring low standby current
Industrial automation systems utilizing capacitive touch interfaces
Smart home appliances with USB connectivity requirements
Portable metering equipment needing precise analog signal processing

Procurement Notes

Verify the specific ordering code suffixes against official Microchip documentation to confirm package type and temperature grade. Ensure compatibility with existing design constraints regarding pinout and power supply specifications before finalizing procurement decisions.

Selection Notes

Select this component when migrating from the SAM D family due to pin compatibility and identical peripheral modules. Consider the SAM L21 series for applications prioritizing ultra-low power consumption over raw processing speed, leveraging the embedded buck/low-dropout regulator for efficient power management.

Part Context

This part belongs to the SAM L21 series of ultra-low-power microcontrollers designed for industrial and consumer applications. It shares architectural similarities with the SAM D21 but offers enhanced power management features such as SleepWalking and multiple sleep modes, making it suitable for battery-operated devices.
