Microcontrollers Procurement Notes

Verify the component status before integration, as this part may be designated as Not Recommended for New Designs (NRND). Confirm that the 100-pin QFP package dimensions align with the target PCB layout. Ensure compliance with moisture sensitivity level requirements during storage and soldering processes to prevent damage. Validate that the 3V to 5V supply voltage matches the system power architecture.

Microcontrollers Selection Notes

Select this MCU when a 16-bit architecture with hardware multiplication is required for cost-effective control applications. Consider the M16C/64A series compatibility if migrating from older M16C designs. Evaluate the 100-pin I/O count against peripheral interface needs. Assess the -20°C to +85°C temperature range against environmental constraints. Review migration guides for transitioning to newer RX series architectures if future scalability is a priority.

Microcontrollers Part Context

This component is part of the broader M16C/64A family, which shares common architectural foundations with other members like the R5F364AMNFA#U0 and R5F364AKNFB#30. These devices utilize the same CPU core and similar peripheral sets, differing primarily in memory capacity and specific pinout configurations. The M16C/64A series serves as a legacy platform for embedded control systems requiring reliable 16-bit performance.

Microcontrollers Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Migration to the RX series is suggested via official application notes, but direct pin-compatible replacements are not listed.
