Overview
The ATSAMD21J16B-MFT is a 32-bit microcontroller based on the ARM Cortex-M0+ core, operating at a maximum frequency of 48MHz. It features 64KB of Flash memory and 8KB of SRAM. The device supports a supply voltage range of 1.62V to 3.6V and includes an internal oscillator. Connectivity options include I2C, LINbus, SPI, UART/USART, and USB interfaces. Analog peripherals consist of twenty 12-bit ADC channels and one 10-bit DAC. The component is housed in a 64-QFN (9x9) package with exposed pad and operates within a temperature range of -40°C to 85°C.
Feature Summary
- Functional Safety (FuSa) compliant design for safety-critical applications
- Integrated DMA controller supporting up to twelve channels for efficient data transfer
- Advanced analog subsystem with multiple high-resolution ADCs and a DAC
- Comprehensive peripheral set including timers, PWM, and standard communication interfaces
Applications
- Industrial control systems requiring functional safety certification
- Medical devices adhering to strict reliability standards
- Automotive infotainment and body electronics modules
- Smart home appliances with connectivity requirements
Procurement Notes
Verify the specific suffix 'MFT' against official Microchip documentation to confirm package type and temperature grade. Ensure compatibility with existing PCB footprints for the 64-QFN form factor. Cross-reference datasheet revisions for any errata affecting pinout or electrical characteristics prior to final procurement decisions.
Selection Notes
Select this model when functional safety compliance is mandatory alongside moderate I/O counts. Compare against non-FuSa variants if safety certification is unnecessary to optimize cost. Evaluate pin availability against application interface needs, as the J-series offers specific peripheral mappings distinct from G or E series counterparts.
Part Context
This component belongs to the SAM D21J family, which is specifically engineered for Functional Safety applications. It shares the Cortex-M0+ architecture with other SAM D21 series members but distinguishes itself through FuSa qualification and specific memory/peripheral configurations tailored for industrial and automotive sectors.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source material. Consult Microchip's official cross-reference tools for verified alternatives.
