Overview
The ATSAMD21G16B-AF 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 clock speed of 48MHz with an internal oscillator. It supports a supply voltage range of 1.62V to 3.6V and includes analog peripherals such as 14-channel 12-bit ADCs and one 10-bit DAC. Connectivity options include I2C, LINbus, SPI, USART, and USB interfaces. The component is housed in a 48-TQFP package and is rated for an operating temperature range of -40°C to 125°C.
Feature Summary
- Functional Safety (FuSa) qualification compliant with AEC-Q100 standards for automotive applications.
- Integrated advanced analog peripherals including multiple high-resolution ADCs and a DAC.
- Supports comprehensive communication protocols including LINbus, SPI, I2C, USART, and USB.
Applications
- Automotive electronic systems requiring functional safety compliance.
- Industrial control devices utilizing LINbus or standard serial interfaces.
- Battery-powered embedded systems leveraging low-power operation modes.
Procurement Notes
Verify the specific suffix 'AF' against official Microchip documentation to confirm the exact package type and temperature grade. Ensure compatibility with required programming interfaces and firmware libraries designed for the SAM D21G FuSa series before integration into production designs.
Selection Notes
Select this model when automotive-grade reliability and functional safety certification are mandatory. It is suitable for designs requiring moderate code storage and robust analog input capabilities within a compact TQFP footprint. Compare against other SAM D21 variants if higher pin counts or different thermal ratings are needed.
Part Context
This component is part of the Microchip SAM D21G family, specifically engineered for functional safety applications. It shares architectural similarities with the broader SAM D21 series but includes additional safety mechanisms and certifications required for automotive environments. The G-series designation typically indicates specific peripheral configurations optimized for cost-sensitive yet reliable embedded solutions.
Replacement Considerations
Direct substitutes include other ATSAMD21G16B variants with different packages, such as ATSAMD21G16B-MU (QFN) or ATSAMD21G16B-AFT (Tape & Reel). Verify that any replacement maintains the same FuSa qualification status and electrical specifications.
