Microcontrollers Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific suffix #V0 matches project requirements. Check current lifecycle status as this model may be subject to discontinuation notices. Ensure compliance with RoHS directives and moisture sensitivity level classifications before procurement.

Microcontrollers Selection Notes

Select this component when a 16-bit architecture with extensive I/O count is necessary. The 80-pin LQFP package suits designs needing significant peripheral connectivity. Consider the 20MHz speed limit and 1.8V-5.5V supply range against system power constraints. Evaluate the availability of sufficient Flash and RAM for application logic and data handling needs.

Microcontrollers Part Context

This part belongs to the R8C/3x family, designed for general-purpose embedded applications. It shares the R8C core architecture with other members like the R5F2138CCNFP#V0 but differs in pin count and memory configuration. The series emphasizes cost-effective performance for mid-range control tasks.
