Microcontrollers Procurement Notes

Verify component status carefully before integration, as this specific part number may be classified as obsolete or not recommended for new designs by the manufacturer. Confirm current availability and lead times directly with authorized distributors. Ensure that the 64-LQFP package dimensions align with existing PCB footprints. Validate that the RX200 series architecture meets all functional requirements for the target application prior to final procurement decisions.

Microcontrollers Selection Notes

Select this microcontroller when a balance of moderate memory capacity and established RX architecture is required. The 64 kB flash size suits applications with complex firmware but limited storage needs. Consider the 32 MHz operating speed for real-time control tasks. Evaluate the 1.8 V to 3.6 V supply range against system power constraints. Compare against newer RX200 variants if future-proofing or enhanced peripheral sets are necessary for long-term product viability.

Microcontrollers Part Context

This component belongs to the Renesas RX200 family, designed for cost-effective embedded solutions. It shares architectural similarities with other RX200 devices but differs in memory size and package options. The RX core offers a strong instruction set optimized for efficiency. This specific model represents a legacy option within the broader RX portfolio, often utilized in established designs where pin compatibility and software libraries are already validated.
