- Up to 256 KB embedded Flash and 32 KB SRAM
- 2.7 V to 5.5 V operating voltage
- Controller Area Network (CAN) interface
- DMA and Event system
- Six (SAM C21J and SAM C21G, four in the SAM C21E) flexible serial communication modules (SERCOM)
- 12-bit ADC (SAM C21J: 20 channels; SAM C21G: 14 channels; SAM C21E: 10 channels)
- 16-bit SDADC (SAM C21J: three channels; SAM C21G: two channels; SAM C21E: one channel)
- Temperature sensor
- Divide and square root accelerator (DIVAS)
- Hardware touch support
- QFP and QFN package options (SAM C21J: 64 pins; SAM C21G: 48 pins; SAM C21E: 32 pins)
