ATSAMD21G15B-MU

Overview

The ATSAMD21G15B-MU is a 32-bit microcontroller based on the ARM Cortex-M0+ core, operating at a maximum frequency of 48 MHz. It features 32 KB of in-system programmable Flash memory and 4 KB of SRAM. The device includes an analog subsystem with fourteen 12-bit ADC channels and one 10-bit DAC. It supports multiple communication interfaces including I2C, SPI, USART, and USB Full-Speed. Powered by a supply voltage ranging from 1.62 V to 3.63 V, it is housed in a 48-lead QFN package and operates within a temperature range of -40°C to +85°C.

Feature Summary

Integrates advanced analog peripherals including a 12-bit ADC and 10-bit DAC for signal processing applications.
Supports comprehensive connectivity options via integrated I2C, SPI, USART, and USB interfaces.
Designed for low-power operation with flexible clocking sources and power management modes.

Applications

Portable consumer electronics requiring compact form factors
Industrial control systems utilizing analog sensor inputs
USB-enabled peripheral devices and host controllers

Procurement Notes

Verify the specific suffix 'MU' confirms the 48-QFN package and commercial temperature grade. Confirm RoHS compliance status through official Microchip documentation prior to procurement. Ensure design-in compatibility with required voltage levels and interface protocols.

Selection Notes

Select this component when 32 KB of program storage and 4 KB of RAM are sufficient for the application logic. Choose this part over higher-capacity variants if cost and pin count optimization are priorities. Verify that the 48 MHz performance meets real-time processing requirements.

Part Context

This unit belongs to the SAM D21G series, which focuses on functional safety and low-power efficiency. It shares architectural similarities with other SAM D21 variants but offers distinct memory configurations. The G-series typically targets general-purpose embedded applications requiring balanced performance and peripheral integration.
