We are working on STM32F103RBT6 and getting the problem in internal EEPROM Read and Write. Please Help me.

The F1 devices don't have any EEPROM.

Perhaps provide some addition context to your question summary.

But Same Controller STM32F103RBT6 EEPROM working With Arduino IDE. And mention the Size of EEPROM in Datasheet .

Where in this document is the term EEPROM mentioned?

Are you talking about EEPROM Emulation, or FLASH?

With FLASH I'd be conscious of different F1 family devices having different sector sizes and banking. And that die substitution has been done by ST in the past to meet quotas.
