Vue d'ensemble

Description

ATSAMD21G17A-AU is a Microchip/Atmel SAM D21 family 32-bit MCU with an ARM Cortex-M0+ core running up to 48 MHz. It provides on‑chip flash and SRAM (sizes vary by variant), USB Full‑Speed device support, multiple SERCOM peripherals (SPI/I2C/UART), a 12‑bit ADC (with multiple channels), timers, DMAC, and an Event System for fast peripheral data transfers. It operates from a 1.6–3.6 V supply and supports low‑power sleep modes for energy efficiency. The -AU suffix denotes a specific package code used by Microchip (check the datasheet for exact pin count and package options). This MCU is suitable for embedded systems, IoT, USB peripherals, sensor nodes, and similar applications. Toolchain support includes MPLAB X, Microchip Studio, and Arduino core for SAM D21. For exact memory sizes and packaging, consult the datasheet.

Pinout

- Pin count: 32 pins (package code AU)
- Function: Microcontroller (Microchip/Atmel SAM D21 family) – 32-bit ARM Cortex-M0+ MCU with on-chip Flash and RAM, USB Full-Speed device, multiple SERCOM peripherals (USART/SPI/I2C), ADC, timers, and up to ~48 MHz operation. Typical memory: 64 KB Flash, 16 KB RAM, operating at 1.8–3.6 V.

Manufacturer

- Manufacturer: Microchip Technology Inc.
- What kind of company: A global semiconductor company based in the United States that designs and manufactures microcontrollers (including SAMD family like ATSAMD21G17A), memory, and analog ICs; publicly traded (NASDAQ: MCHP) and owns the Atmel line (acquired 2016).

Application

ATSAMD21G17A‑AU is a low‑power Cortex‑M0+ MCU with USB 2.0 device, SERCOM, 12‑bit ADC and PWM. Key applications include:
- USB-enabled peripherals (HID, CDC, mass storage bootloaders)
- IoT/sensor nodes and smart meters (low power, sleep modes)
- Wearables and portable devices
- Consumer electronics and home automation (remotes, hubs, switches)
- Data acquisition, logging and automation in industrial/applications
- Rapid prototyping and education boards (Arduino Zero family)

Equivalent

Equivalent products are other SAM D21 devices from Microchip with the same memory and peripherals in different packages. Pin-compatible options include the same silicon in alternate package codes (e.g., ATSAMD21G17A-MU). For exact substitutes, specify the desired package and memory requirements (flash/RAM); I can give a precise cross-reference.
