ATSAMD21G15B-AFT

Overview

The ATSAMD21G15B-AFT is a 32-bit microcontroller based on the ARM Cortex-M0+ core, belonging to the SAM D21G Functional Safety (FuSa) series. It features 64KB of flash memory and 8KB of SRAM. The device operates at a maximum frequency of 48MHz with an internal oscillator. It supports a supply voltage range of 1.62V to 3.6V and functions within a temperature range of -40°C to 125°C. The component is housed in a 48-TQFP package and includes analog converters such as 14x12-bit ADCs and 1x10-bit DAC.

Feature Summary

Functional Safety (FuSa) certification for automotive applications
Integrated advanced analog peripherals including multiple ADC channels
Support for LINbus communication protocols alongside standard interfaces

Applications

Automotive body electronics systems
Industrial control units requiring functional safety compliance
Consumer devices operating in extended temperature environments

Procurement Notes

Verify the specific suffix AFT corresponds to the 48-TQFP package and industrial temperature grade when sourcing. Confirm that the Functional Safety qualification aligns with your system's safety integrity level requirements. Check for any recent product change notices regarding assembly or packaging modifications from Microchip Technology before finalizing procurement plans.

Selection Notes

Select this model when automotive functional safety standards are mandatory and high-temperature operation up to 125°C is required. Compare pin counts and peripheral sets against other SAM D21 variants like the E or J series if fewer I/Os suffice. Ensure the 48MHz clock speed meets processing demands without necessitating higher-performance cores.

Part Context

This component is part of the SAM D21 family, specifically designed for applications demanding reliability and safety certifications. The G-series designation indicates automotive-grade qualification under AEC-Q100 standards. It shares architectural similarities with non-safety variants but includes additional verification for functional safety compliance.
