TMP1826: User Memory Write Protection methods of Verifications

Part Number: TMP1826

Tool/software:

Hi there,

I am implementing the write-protection (page locking) on the user memory eeprom pages.

Can I know what are all the methods to verify that locking is done successfully?

Is there any other methods other than attempting to write and read the eeprom pages after locking and check that the Eeprom is the original content before locking.

Any development tools that you could recommend as well would be greatly appreciated.

Best Regards,

Carl

Hi Carl,

There isn't a method that I see for the TMP1826 device to report page protection status. I think you will have to attempt to write to the EEPROM to confirm that the page protection worked.

There is example code on the product page https://www.ti.com/product/TMP1826#software-development which has a SetNVMProtection function you can refer to. There is also example code inside ASCStudio https://dev.ti.com/sysconfig/index.html?product=ascstudio&module=/ti/sensors/tempsensor/TMP1826 which has a TMP1826_lockEEPROM function you can refer to.

thanks,

ren
