ATSAMD21E16B-MUT

Overview

The ATSAMD21E16B-MUT is an ARM microcontroller from the SAM D21E series, featuring a Cortex-M0+ core operating at 48 MHz. It integrates 64 kB of Flash memory and 8 kB of SRAM within a 32-pin QFN 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 interfaces such as I2C, SPI, USART, I2S, and LIN. It holds AEC-Q100 qualification for automotive applications.

Feature Summary

Functional Safety (FuSa) certified architecture compliant with ISO 26262 standards
Integrated USB 2.0 full-speed controller for communication connectivity
Direct Memory Access (DMA) engine for efficient data transfer management
Low-power operation modes including idle, sleep, standby, and hibernate

Applications

Automotive infotainment systems requiring functional safety certification
Industrial control devices utilizing LIN bus communication
Portable consumer electronics powered by single-cell lithium batteries
Smart home sensors and actuators with low power requirements

Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging when ordering. Confirm the temperature grade corresponds to the industrial range (-40°C to +85°C). Ensure compatibility with existing PCB footprints for the 32-QFN package. Check for any recent product change notices regarding pinout or electrical characteristics updates from Microchip Technology.

Selection Notes

Select this component when functional safety compliance is mandatory for the application. Choose the tape-and-reel variant for automated surface-mount assembly processes. Consider the 64 kB memory limit for complex firmware requirements. Evaluate the 26 available I/O pins against interface needs before finalizing the design.

Part Context

This part belongs to the SAM D21E family, specifically designed for automotive and industrial markets. It shares architectural similarities with the standard SAM D21 series but includes enhanced safety features. The 'E' designation denotes the extended automotive/industrial grade. It serves as a robust alternative to general-purpose MCUs in safety-critical environments.
