Microcontrollers Procurement Notes

Verify the specific ordering suffix '-120' against official Microchip documentation to confirm the 120 MHz speed grade and package configuration. Ensure compatibility with development tools such as MPLAB X IDE and XC32 compilers. Confirm that the selected package variant matches the required pin count and thermal specifications for the target PCB layout.

Microcontrollers Selection Notes

Select this component when a balance of processing power and peripheral integration is required for embedded applications. The 120 MHz core offers higher performance than standard 80 MHz variants while maintaining pin compatibility with lower-speed models. Consider the available memory size and the presence of specialized peripherals like the CTMU and USB OTG for system requirements.
