MCHPATSAMD21G17D-AZVAO

Overview

The ATSAMD21G17D-AZVAO is a Microchip SAM D21 series ARM Cortex-M0+ microcontroller in a 48-pin TQFP package. It is aimed at low-power embedded designs and includes USB support, making it useful for compact USB-connected products and prototypes.

Why Choose This Part

This part combines a Cortex-M0+ core with on-chip flash, USB support, and an extended-temperature grade, which makes it practical for compact embedded designs. The 48-pin TQFP package is manageable for PCB assembly while still giving access to a useful set of I/O and peripherals. It is also well supported by the broader SAM D21 ecosystem, which helps reduce bring-up time.

Applications

Getting Started

For development, look at Microchip's SAM D21 Curiosity Nano and other SAM D21 evaluation boards, then use MPLAB X IDE with the XC32 toolchain or Arm GCC-based workflows. The device is also commonly used with Arduino-compatible cores in the SAM D family, which can speed up initial firmware bring-up. For first-time hardware work, confirm the exact pinout, clock source, and USB design requirements before laying out the board.
