    Software reset sequence of Serial FRAM (FM24CL64B)



      Several I2C EEPROMs have a software reset sequence.

      When the power-on EEPROM falls into an incorrect state (due to excessive bus noise, etc.)

      or when the microcontroller is reset during communication.

      In such a case, the serial EEPROM device can reset correctly by sending the following sequence.


      • Start bit

      • 9-bit "1" clock

      • Start bit

      • Stop bit


      Is it possible to perform a software reset also in FRAM of Cypress?
