In this tutorial we will discuss how to access the PIC16F877A internal EEPROM memory to store and retrieve the data. Eeprom is basically used to store the non volatile data which is required to be stored even if there is power loss or controller resets.
PIC16F877A Memories
PIC16F877A comes with three memories Flash,RAM and EEPROM. Below table shows the memory capacity of PIC16F877A:
| Memory | Size | Description |
|---|---|---|
| FLASH | 8k-bytes | Used to store the programs |
| RAM | 368-bytes | Temporary/ScratchPad memory used during program execution. |
| EEPROM | 256-bytes | Used to store the non-volatile data across power cycles |
