Microcontrollers Procurement Notes

Verify that the ordering suffix corresponds to the SOIC package type and the -V temperature grade. Confirm the specific revision level matches project requirements. Ensure compatibility with existing PCB footprints designed for 28-pin narrow SOIC components. Cross-reference the datasheet revision date to validate feature availability.

Microcontrollers Selection Notes

Select this component when a balance of processing power and integrated USB connectivity is required in a compact form factor. The 28-pin SOIC package suits designs prioritizing surface-mount assembly on standard boards. Consider the 50 MHz performance ceiling and 64 KB RAM limit against application complexity before finalizing the choice.

Microcontrollers Part Context

This part belongs to the PIC32MX2XX series of 32-bit microcontrollers, which are distinguished by their inclusion of USB On-The-Go controllers compared to the general-purpose PIC32MX1XX series. The family shares a common MIPS32 M4K core architecture but varies in memory sizes and pin counts. The -V suffix indicates the extended industrial temperature rating suitable for demanding environments.

Microcontrollers Replacement Considerations

Direct replacements within the same package and pinout include other PIC32MX270 variants with different suffixes, such as PIC32MX270F256B-I/SO for commercial temperature ranges. Verify electrical specifications and memory configurations match exactly when substituting.
