SAMD1x/2x MCU Family Reference
This page connects you with all the information you need to evaluate and design with Microchip's 32-bit SAMD1x/2x families of microcontrollers.
Family Overview
| SAM D10 SAM D11 | SAM D10 microcontroller is the smaller member of this family with serial interfaces, timers, analog comparators and a Peripheral Touch Controller (PTC). SAM D11 adds full speed USB device. - Arm® Cortex® -M0+ core @ 48 MHz - Lowest cost - Low power and USB (SAMD11) |
| SAM D20 SAM D21 | SAM D20 adds memory and peripherals to the SAMD1x family. SAM D21 adds a full-speed host and device USB, DMA, and timer counter for control. - Arm Cortex -M0+ core @ 48 MHz - Lowest cost - Low power and USB (SAMD21) |
| SAM D21 L | SAM D21 L adds peripherals specialized for motor control. - Arm Cortex -M0+ core @ 48 MHz - Lowest cost - Motor control (SAMD21 L) |
| SAM DA1 | SAM DA1 has been qualified for automotive applications per AEC-Q100 grade 1. - Arm Cortex -M0+ core @ 48 MHz - Low power and USB |
