Overview
The ATSAMC21J17A-MUT is a 32-bit microcontroller based on the ARM Cortex-M0+ core, operating at a maximum frequency of 48 MHz. It features 128 KB of in-system programmable Flash memory and 16 KB of SRAM. The device supports a supply voltage range of 2.7 V to 5.5 V and includes 52 general-purpose I/O pins. Integrated peripherals include 20 channels of 12-bit ADC, one 10-bit DAC, and multiple communication interfaces such as SPI, I2C, USART, LINbus, and PMBus. It is housed in a 64-VFQFN package with an exposed pad.
Feature Summary
- Supports automotive-grade reliability through AEC-Q100 qualification for extended temperature ranges.
- Integrates comprehensive analog conversion capabilities with high-resolution ADC and DAC channels.
- Provides versatile connectivity via multiple serial communication protocols including LINbus and PMBus.
Applications
- Automotive body electronics and control modules
- Industrial sensor nodes requiring LINbus or PMBus interfaces
- Consumer devices needing robust 5V operation
Procurement Notes
Verify the specific suffix 'MUT' corresponds to the 64-VFQFN (9x9) package and tape-and-reel shipping configuration. Confirm that the AEC-Q100 qualification aligns with your target application's environmental requirements. Ensure compatibility with the 2.7V to 5.5V supply voltage range for your system design.
Selection Notes
Select this component when a 5V-tolerant ARM Cortex-M0+ MCU with automotive certification is required. It is suitable for designs needing 128 KB of program memory and extensive analog input channels. Consider alternatives if higher clock speeds or larger RAM capacities are necessary.
Part Context
This part belongs to the Microchip SAM C21 family, which is designed for cost-sensitive applications requiring low power consumption and small form factors. The J-series variant specifically offers a balance of performance and peripheral richness within the 64-pin package constraint.
Replacement Considerations
ATSAMD21J17A-MUT is a similar 3.3V-only variant from the SAM D21 family but lacks AEC-Q100 qualification. For direct pin-compatible upgrades within the SAM C21 series, consider ATSAMC21J18A-MUT for increased memory capacity.
