4 Design Considerations

  1. There are three user-configurable parameters in eeprom_emulation_type_a.h. These parameters can be configured accordingly, depending on the requirements of the application. To set appropriate parameters, see the application aspects section in the EEPROM Emulation Type A Design application note.
    1. Record size: 64, 128, or 256 bytes
    2. Number of sectors used: at least 2
    3. Sector address
  2. To evaluate the Flash usage and cycling capability, see the application aspects section in the EEPROM Emulation Type A Design application note.
  3. Data or header corruption is possible in case of a power loss during a EEPROM_TypeA_writeData or EEPROM_TypeA_eraseLastSector.

    To detect, and recover from corruption, implement EEPROM_TypeA_init. Call EEPROM_TypeA_initimmediately after power-up. EEPROM_TypeA_init checks all the headers of the records to confirm whether data storage of EEPROM emulation is correct, and performs format-repair, if necessary.

    In the structure of EEPROM emulation, headers show the status of the corresponding records. There are four states in total. The changes between the four states are described in detail in Section 3.
