PSOC 5 using EEPROM

[Anonymous]

I using the PSOC 5 in a modbus application.  I would like to configure the EEPROM to store a new modbus address and to store 7 floating point calibration values.  Functionally the solution work but the EEPROM Write utilities take more time than the modbus timeouts.

       

Question:  What is the time required to write an EEPROM byte and write an EEPROM row?

       

Thanks for responses

        I believe ~20ms, it is always a row, not byte

EEProm datasheet AC specs show : Row erase/write cycle time is typ. 10ms, max 20ms.

   

Because a row is the smallest amount to program, the time to change a byte is roughly the same as for the row.

Thanks for all your help.  What I found key was to organize EEPROM data into 16 byte pages and transfer data on the modbus 16 bytes at a time.  Then EEPROM_StartWrite function call can be used, which allows processing to continue.
