Microcontrollers Procurement Notes

Verify the specific suffix #UB against official Renesas documentation to confirm exact manufacturing lot or revision details. Ensure compatibility with existing PCB footprints for the LQFP-144 package. Confirm that the 3V to 5.5V supply range aligns with the target system power design. Check current availability status as this part may be subject to lifecycle changes.

Microcontrollers Selection Notes

Select this component when a balance of high processing speed and rich peripheral integration is required. The 150 MHz clock speed offers significant performance over standard 50 MHz variants in the same family. Consider the 144-pin form factor for designs needing a high density of general-purpose I/O lines without external multiplexing.

Microcontrollers Part Context

This model belongs to the R32C/100X_150 group, an evolution of the popular R32C/100 series. It shares architectural similarities with parts like the R5F64179PFB but distinguishes itself through increased clock speeds and expanded memory resources. It serves as a mid-to-high-end solution within the Renesas 32-bit MCU portfolio for complex embedded tasks.

Microcontrollers Replacement Considerations

Direct pin-compatible alternatives within the same package may include other members of the R5F641xxDFD series with varying memory sizes. Verify software compatibility if migrating between different memory capacities within the same core family.
