Overview

The ATSAMC21G18A-AUT is a 32-bit ARM Cortex-M0+ microcontroller designed for high-performance industrial and automotive applications. It features a 48MHz operating frequency, 256KB of Flash memory, and is specifically engineered for robust operation in 5V environments.

Why Choose This Part

This MCU stands out by offering dual CAN-FD interfaces and a true 5V operating voltage, which eliminates the need for level shifters in many industrial systems. It provides superior noise immunity and a robust peripheral set including a Peripheral Touch Controller and advanced analog capabilities.

Applications

Automotive Body Control
Ideal for windshield wipers, lighting control, and window lifts requiring 5V signaling and CAN connectivity.
Industrial Motor Control
Utilizes integrated hardware for Pulse Width Modulation (PWM) and high-speed analog-to-digital conversion to manage brushless DC motors.
Appliances and White Goods
Provides high noise immunity in electrically noisy environments typical of washing machines and dryers.
Sensor Hubs
Aggregates data from multiple analog sensors using its dual 12-bit ADCs and Sigma-Delta ADC interfaces.

Getting Started

Start development using the SAM C21 Xplained Pro evaluation kit (ATSAMC21-XPRO). Use the Microchip Studio or MPLAB X IDE with the XC32 compiler and Atmel START for rapid peripheral configuration and driver generation.
