Last modified by Microchip on 2023/11/09 09:01

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 a 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
