Microcontrollers Procurement Notes

Verify the specific suffix #V0 against official documentation to confirm manufacturing details or revision status. Confirm that the D version designation aligns with the required -40°C to +85°C operating temperature range for your application environment. Ensure compatibility with existing system voltage levels and interface requirements before finalizing procurement.

Microcontrollers Selection Notes

Select this component when a 16-bit architecture with integrated data flash and background operation is required. The 80-pin LQFP package suits designs needing extensive I/O capabilities. Consider the 20 MHz maximum speed and available memory sizes relative to software complexity. Verify peripheral availability matches specific communication and conversion needs.

Microcontrollers Part Context

This part belongs to the R8C/38C Group, which shares common architectural features such as the R8C CPU core and peripheral configurations. Variations within the group primarily differ in memory capacities and operating temperature ranges. The 'D' suffix indicates the industrial temperature grade, while the base model defines the specific memory configuration and package type.

Microcontrollers Replacement Considerations

Consult the official product list for other members of the R8C/38C Group with matching pinouts and memory sizes. Verify functional equivalence regarding peripheral availability and electrical characteristics before substituting.
