Overview
The ATSAMD21E16B-MU is a 32-bit microcontroller based on the ARM Cortex-M0+ core, operating at a maximum frequency of 48 MHz. It features 64 kB of Flash program memory and 8 kB of SRAM data memory. The device includes a 12-bit ADC with 10 channels and a 10-bit DAC. It supports multiple communication interfaces including I2C, I2S, LIN, SPI, and USART. The unit operates within a voltage range of 1.62 V to 3.63 V and functions in temperatures from -40°C to +85°C. It is housed in a 32-pin QFN package.
Feature Summary
- Functional Safety (FuSa) qualification compliant with AEC-Q100 standards for automotive reliability.
- Integrated advanced analog peripherals including high-resolution ADCs and PWM generators.
- Supports low-power operation modes suitable for battery-constrained embedded applications.
Applications
- Automotive infotainment systems requiring functional safety compliance.
- Industrial control units utilizing LIN bus communication.
- Consumer electronics devices needing efficient power management.
Procurement Notes
Verify the specific suffix 'MU' confirms the 32-QFN package and industrial temperature grade. Confirm RoHS compliance status through official Microchip documentation. Ensure the Functional Safety (FuSa) designation matches project requirements. Check for any recent Product Change Notifications regarding assembly or fabrication sites.
Selection Notes
Select this component when AEC-Q100 qualification is mandatory for the application. Compare against ATSAMD21G16B-MU if higher pin counts are needed. Consider ATSAMD20E16A-MU if 5V operation is required instead of 3.3V logic levels. Evaluate pin availability against interface requirements such as USB or additional timers.
Part Context
This part belongs to the SAM D21E series, which focuses on Functional Safety applications. It shares the Cortex-M0+ architecture with other SAM D21 variants but offers specific automotive-grade validation. The E-series designation typically indicates a subset of features optimized for cost-sensitive yet reliable environments compared to the G or J series.
Replacement Considerations
ATSAMD21E16B-MUT serves as the tape-and-reel equivalent of this tray-packaged component. For non-automotive applications, the ATSAMD21G16B-MU provides similar specifications with increased I/O count.
