CC2430: Flash Lock

Part Number: CC2430

Hi All,

In one of the application I am using CC2430 RF IC. I am write protecting all Flash by setting LSIZE = "000".

The question I have is,

After write protecting 128kB (all Flash bytes) from CC2430 can we access and write into flash through available SPI?


  • Hi Sanket,

    This has not been tested recently given that the device is NRND, but if flash memory is write protected then logically you should not be able to write to memory using flash operations regardless of the method used.  You could leave some memory areas as writeable or write data to an external flash memory storage device.
