• Automotive applications utilizing LIN bus communication protocols
• General-purpose embedded systems needing multiple serial communication interfaces

Microcontrollers Procurement Notes

Verify the specific suffix HAA against official Renesas documentation to confirm package type and temperature grade. Confirm that the 78K0R/IX3 series status aligns with current design-in recommendations, as legacy support may apply. Ensure compatibility with existing development tools like CubeSuite+ for programming and debugging requirements.

Microcontrollers Selection Notes

Select this component when a 16-bit architecture with high clock speeds up to 40MHz is required alongside significant analog input channels. It is suitable for designs needing integrated LIN and UART connectivity without external transceivers. Consider the 48-pin TQFP form factor for board space constraints while ensuring the 2.7V to 5.5V supply range matches the system power rails.

Microcontrollers Part Context

This part belongs to the 78K0R/IX3 group, which is positioned within Renesas' broader portfolio of 8-bit and 16-bit microcontrollers. While the 78K0R/Lx3 family is noted for LCD display applications, the IX3 variant emphasizes enhanced connectivity and performance. It serves as a specialized solution for customers requiring robust peripheral integration in industrial and automotive sectors.

Microcontrollers Replacement Considerations

Consult official Renesas substitution guides for direct equivalents. Verify pin-to-pin compatibility if considering upgrades within the 78K0R family. Ensure software migration paths are evaluated if moving to newer RL78 or RH850 architectures.
