Microcontrollers Procurement Notes

This component is officially designated as End-of-Life (EOL) by Renesas Electronics. Availability is restricted, and procurement should focus on verifying stock status through authorized channels. Buyers must review discontinuation notifications and plan for alternative sourcing or redesigns due to limited supply longevity.

Microcontrollers Selection Notes

Select this part only if legacy V850 architecture compatibility is required. Verify that the 100-lead package fits the target PCB layout. Ensure the design accounts for the specific memory configuration of 1024 KB ROM and 80 KB RAM. Confirm that the E3 suffix aligns with environmental compliance requirements for the intended market.

Microcontrollers Part Context

This MCU belongs to the V850ES/SG3 family, designed for applications demanding high cost-performance and robust peripheral integration. It shares architectural similarities with other V850 variants but is distinguished by its specific memory map and lead count. The series targets complex control tasks requiring significant code space and data handling capabilities.

Microcontrollers Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Due to the EOL status, direct pin-to-pin replacements may not be listed; system redesign or long-term inventory management is recommended.
