ATSAMC21J15A-MUT

Overview

The ATSAMC21J15A-MUT is an ARM microcontroller from the Microchip ATSAMC21 series, featuring an ARM Cortex-M0+ core. It operates at a maximum clock frequency of 48 MHz and includes 32 kB of Flash program memory and 4 kB of SRAM data RAM. The device provides 52 general-purpose I/O pins and supports a supply voltage range of 2.7 V to 5.5 V. It integrates a 12-bit ADC with 20 channels and a 10-bit DAC. Communication interfaces include LIN, I2C, PMBus, Serial, SPI, and USART. The component is housed in a 64-VQFN package and is qualified under AEC-Q100 standards for automotive applications.

Feature Summary

• Automotive-grade reliability certified by AEC-Q100 qualification standards
• Integrated analog peripherals including a 20-channel 12-bit ADC and a 10-bit DAC
• Supports multiple serial communication protocols such as SPI, I2C, LIN, and USART

Applications

• Automotive body electronics and control modules
• Industrial sensor nodes and monitoring systems
• Consumer devices requiring robust MCU performance

Procurement Notes

Verify the specific suffix 'MUT' corresponds to the 64-VQFN package and tape-and-reel delivery format. Confirm the temperature grade matches the required operational environment, as indicated by the product description. Ensure compatibility with existing PCB footprints for the VQFN-64 housing. Check for any regional compliance requirements beyond RoHS directives.

Selection Notes

Select this model when a balance of moderate pin count and automotive certification is required. The 32 kB Flash size suits applications with constrained code storage needs. Consider alternative SAMC21 variants if higher memory capacity or different package types are necessary. Evaluate power consumption profiles against system battery life requirements.

Part Context

This component belongs to the ATSAMC21 family of 32-bit microcontrollers based on the ARM Cortex-M0+ architecture. The family offers various memory sizes and package options tailored for cost-sensitive and high-volume applications. The J-series designation typically indicates a specific pin count and peripheral set within the broader SAMC21 portfolio.

Replacement Considerations

Direct substitutes within the same package and memory configuration may include other ATSAMC21JxxA-MUT variants with differing Flash sizes, such as ATSAMC21J18A-MUT. Cross-family replacements require careful verification of pin compatibility and software migration efforts.
