Microcontrollers Procurement Notes

Verify the specific suffix #X6 against official Renesas documentation to confirm package type and tape/reel configuration, as suffixes often denote packaging variations rather than functional changes. Confirm current lifecycle status, as R8C series components may be designated as Not Recommended for New Designs (NRND). Ensure compatibility with existing PCB footprints for the 64-LQFP package before procurement.

Microcontrollers Selection Notes

Select this component when a 16-bit architecture with moderate Flash capacity and extensive I/O is required. The R8C/2B series offers a balance of processing speed and peripheral integration suitable for cost-sensitive applications. Consider the 20 MHz maximum frequency and 5.5 V max voltage rating for system design constraints. Evaluate alternative packages if surface mount space is limited.

Microcontrollers Part Context

This part belongs to the R8C/2B family of 16-bit microcontrollers from Renesas Electronics. The R8C series is known for its high-performance CISC architecture and rich peripheral set. The R5F212B8 variant specifically targets applications needing reliable control with integrated communication interfaces. The #X6 suffix typically indicates a specific tape and reel packaging option for automated assembly.

Microcontrollers Replacement Considerations

Direct pin-to-pin replacements within the same package and memory configuration should be verified via Renesas cross-reference tools. Other members of the R8C/2B series with identical or greater Flash/RAM sizes may serve as substitutes. Ensure any replacement maintains support for required peripherals like LINbus or UART.
