AM2432: OTP eFuse for storing keys

Prithvi Joshi

Part Number: AM2432

Hi Expert,

We are using AM2432BSFFHIALVR. For a cyber security requirement, we are looking to store some keys in the OTP (eFuse) of the device.

1. Does our device support programming of keys to OTP?

2. If yes, can we get some tools, documentations regarding this?

Thanks,

Prithvi

Thanks for the reply Aakash.

We are currently using 08.02.00.31 version of SDK. Can we still go ahead with this version for programming OTP?

Thanks,

For compatibility reasons, I would suggest you to request for 08.02 version of OTP Keywriter or to migrate to newer version of SDK i.e. 08.04.00.17

Hi Prithvi,

My recommendation would be to migrate to newer SDK as the security support officially started with 08.04 release.
