ATSAMC21E16A-AUT

Overview

The ATSAMC21E16A-AUT is an automotive-grade ARM microcontroller from the Microchip SAM C21 family, built on the 32-bit ARM Cortex-M0+ core. It features 64 kB of Flash program memory and 8 kB of SRAM data memory. The device operates with a maximum clock frequency of 48 MHz and supports a supply voltage range of 2.7 V to 5.5 V. It includes a 12-bit ADC with 10 channels and a 10-bit DAC. The component is housed in a TQFP-32 package and is qualified to AEC-Q100 standards for operation within a temperature range of -40°C to +85°C.

Feature Summary

Automotive qualification compliant with AEC-Q100 standards for reliable performance in vehicle environments.
Integrated 2.4 GHz IEEE 802.15.4 radio subsystem supporting ZigBee and Thread wireless protocols.
Low-power architecture designed for energy-efficient operation in battery-powered applications.
Comprehensive peripheral set including multiple communication interfaces and high-resolution analog converters.

Applications

ZigBee and Thread smart home devices
Industrial wireless sensor nodes
Building automation controllers
Medical telemetry equipment

Procurement Notes

Verify the specific suffix 'AUT' confirms automotive grade qualification and the '-T&R' designation indicates tape and reel packaging. Confirm the operating temperature range matches the application requirements of -40°C to +85°C. Ensure the TQFP-32 package type aligns with the PCB footprint design. Cross-reference the datasheet for any specific handling instructions related to moisture sensitivity level.

Selection Notes

Select this component when an automotive-compliant MCU with integrated 2.4 GHz wireless capabilities is required. It is suitable for designs needing moderate processing power with low current consumption. Compare against non-automotive variants if environmental ruggedness is not critical. Consider pin compatibility with other SAM C21 family members for potential future scaling.

Part Context

This part belongs to the Microchip SAM C21 series, which integrates ARM Cortex-M0+ cores with wireless connectivity. The series targets IoT applications requiring secure, low-power communication. The ATSAMC21E16A variant specifically provides 64 kB of flash memory, balancing code storage needs with cost efficiency for mid-range embedded systems.
