How to Choose the Right 32-bit MCU for Your Application
Selecting the right 32-bit microcontroller depends on your application's performance, connectivity, and peripheral requirements. Our technical experts recommend considering these key factors:
Performance Requirements
For applications requiring high computational performance, consider the PIC32MZ or SAM G series with up to 200MHz operation. For general-purpose applications, the PIC32MX or SAM D series provide excellent performance-per-watt efficiency.
Connectivity Needs
If your application requires rich connectivity options, select devices with integrated Ethernet, CAN, or USB Hi-Speed interfaces. The PIC32MZ series offers the broadest connectivity options.
Power Consumption
For battery-powered or power-sensitive applications, the SAM L series or PIC32MM offer excellent low-power features with sophisticated sleep modes and wake-up capabilities.
Security Requirements
Applications with security requirements should consider the PIC32MZ family with integrated security features or SAM devices with hardware security modules.
