ATSAMD20G17A-MU

Overview

The ATSAMD20G17A-MU is a 32-bit microcontroller based on the ARM Cortex-M0+ core, operating at a maximum frequency of 48MHz. It features 128kB of Flash program memory and 16kB of SRAM data memory. The device includes one 12-bit analog-to-digital converter with 14 channels. It supports I2C, SPI, and UART/USART interfaces but lacks USB connectivity. Operating voltage ranges from 1.62V to 3.63V, with an extended temperature range of -40°C to +85°C.

Feature Summary

ARM Cortex-M0+ processor core for efficient low-power execution
Integrated 12-bit ADC with multiple input channels for sensor interfacing
Standard serial communication peripherals including I2C, SPI, and UART

Applications

Low-power embedded control systems
Sensor data acquisition nodes
Industrial monitoring devices

Procurement Notes

Verify the specific suffix against official Microchip documentation to confirm package type and temperature grade. Ensure compatibility with required voltage levels and interface configurations before integration. Cross-reference datasheet revisions for any errata or pinout changes relevant to the design.

Selection Notes

Select this component when a balance of processing capability and power efficiency is required without USB functionality. Compare against SAMD21 series if additional peripherals like DAC or USB are needed. Confirm that the TQFP package fits the board layout constraints.

Part Context

This part belongs to the Microchip SAM D20 family, designed for cost-sensitive applications requiring reliable performance. It shares architectural similarities with other SAMD variants but offers specific memory and peripheral configurations tailored for general-purpose microcontroller tasks in compact form factors.
