Procurement Notes

Verify the specific suffix designation to confirm the exact clock frequency variant, as the base model supports multiple speeds. Confirm RoHS compliance status through official documentation before procurement. Check for end-of-life notifications or discontinuance alerts from Renesas Electronics. Ensure storage conditions account for moisture sensitivity classification during handling. Validate package dimensions against PCB footprint requirements prior to ordering.

Selection Notes

Select this component when a CMOS UART with low power consumption and high noise immunity is required. Compare performance metrics against alternative UART controllers regarding data rate limits and clock speed options. Evaluate the PLCC-28 package suitability for the target assembly process. Consider the operating temperature range constraints relative to the application environment. Verify compatibility with the host microprocessor's voltage levels and timing requirements.

Part Context
