What is the difference between ecc608 and tpm?

Could you please tell me about the the major difference between ecc608 and tpm? And what are the typical applications of ecc608 and tpm?

    I assume "ecc608" is https://www.microchip.com/wwwproducts/en/ATECC608A
    What is "tpm" ?
    Why are your questions so terse?

    TPM is "Trusted Platform Module (TPM, also known as ISO/IEC 11889) is an international standard for a secure cryptoprocessor, a dedicated microcontroller designed to secure hardware through integrated cryptographic keys." 


    ECC608 is mentioned as "The ATECC608A is a secure element from the Microchip CryptoAuthenticationTM portfolio with advanced Elliptic Curve Cryptography (ECC) capabilities. " 
     
    It seems that they have similar functionality, but I don't understand what are the differences between ecc608 and TPM.

    ... and here was me wondering what ecc608 had to do with Tire Pressure Monitoring.
    Avoid acronyms when there's no context to make clear what you are talking about.

    @rik, here TPM I meant is that "Trusted Platform Module (TPM, also known as ISO/IEC 11889)" rather than "Tire Pressure Module".

    My point was you should have mentioned that in the first post.

    Hi,
    My understanding is that ECC608A is an authentication device mostly used for identification by the cloud from the end node (valid signature of the remote device) whereas TPM is generally used as a local device to secure bootloading. e.g. PCs use TPM because they want to make sure that a new BIOS firmware has a valid signature an has not been compromised by hackers
    Regards
