Microcontrollers Procurement Notes

Verify the specific suffix 'MR' corresponds to the QFN package type required for your design. Confirm that the '-40V' designation matches the intended operating temperature range and voltage specifications. Ensure compatibility with existing firmware libraries designed for the PIC32MX4xx family before finalizing procurement.

Microcontrollers Selection Notes

Select this component when a balance of moderate Flash capacity and integrated USB connectivity is required. It is suitable for applications needing up to 40 MHz processing speed without the higher cost or complexity of larger memory variants. Consider the available GPIO count and peripheral set against project requirements.

Microcontrollers Part Context

This part belongs to the PIC32MX4xx series of high-performance, general-purpose, and USB-enabled 32-bit Flash microcontrollers. It shares architectural similarities with other members of the MX3XX/4XX family but offers specific memory sizes and clock speeds tailored for mid-range embedded applications requiring USB functionality.

Microcontrollers Replacement Considerations

Check for pin-compatible alternatives within the PIC32MX4xx series such as the PIC32MX440F128H if higher performance is needed. Verify software compatibility when substituting with other Microchip 32-bit MCUs.
