Microcontrollers Procurement Notes

Verify component authenticity through authorized Renesas distributors or direct manufacturer channels. Confirm RoHS compliance status and check for End-of-Life notices, as this specific part number may be discontinued. Ensure packaging specifications match design requirements before finalizing procurement orders.

Microcontrollers Selection Notes

Select this component for applications requiring a 16-bit architecture with moderate memory capacity in a compact surface-mount package. Consider the 20MHz processing speed and available peripheral set against system timing and interface needs. Evaluate thermal performance within the specified operating temperature range during hardware design.

Microcontrollers Part Context

This microcontroller belongs to the R8C/1B group, which represents a legacy line of 16-bit MCUs from Renesas Electronics. These devices are designed for cost-sensitive applications requiring reliable processing power. New designs are often directed toward modern alternatives like the RL78/G12 series, while existing products may continue support for established customer bases.

Microcontrollers Replacement Considerations

Consult official Renesas documentation for confirmed substitute part numbers within the same family or recommended newer generations. Verify pin compatibility and software migration paths when transitioning to alternative components.
