KL8x current draw for LP Trusted Crypto (LTC)

Hello,

I'm looking into low power uCs for a battery operated application. I don't seem to find the info on the power draw for the LTC (crypto) module available in the KL8x. I assume this may be a large value due to the complexity of the encryption/decryption operation so I should definitely consider it for the overall power consumption.

I'm looking in the KL82P121M72SF0 document and this info doesn't appear to be listed.

Should I be looking elsewhere?

Regards,

Andrei
