Microcontrollers Procurement Notes

Verify the specific suffix #00 against official Renesas documentation to confirm pinout and electrical characteristics. Confirm moisture sensitivity levels and recommended reflow profiles prior to assembly. Ensure compatibility with existing PCB footprints for the 32-HVQFN package. Cross-reference part numbers with current Renesas production status to avoid obsolescence risks during manufacturing.

Microcontrollers Selection Notes

Select this component when industrial-grade temperature ratings are mandatory. The combination of 32 MHz processing speed and dedicated cryptographic hardware suits security-conscious designs. Evaluate the 32-pin form factor against available board space constraints. Consider the 2.5 V to 5.5 V input range for flexible power supply architectures in harsh environments.

Microcontrollers Part Context

This unit belongs to the RL78/I1E family, which targets industrial markets with enhanced reliability features. The I1E series distinguishes itself through extended temperature ranges and specialized peripheral sets compared to general-purpose counterparts. It shares architectural similarities with other RL78 variants but offers optimized support for industrial communication protocols and safety-critical operations.

Microcontrollers Replacement Considerations

Consult Renesas official cross-reference tools for verified substitutes. Potential alternatives within the RL78/I1E family may offer different memory configurations or package options while maintaining functional compatibility.
