Logic circuitry packages for replaceable print apparatus components

A logic circuitry package for a replaceable print apparatus component comprising an interface to communicate with a host logic circuit, and

• a logic circuit configured to:
• include a plurality of personalities, each personality of the plurality of personalities comprising an ID and a cryptographic key;
• start a cryptographic session with the host logic circuit using a selected personality of the plurality of personalities;
• transmit a consumable level value to the host logic circuit in response to a request from the host logic circuit independent of which personality of the plurality of personalities is the selected personality;
• receive, from the host logic circuit, a query ID command upon powerup of the logic circuitry package;
• transmit, to the host logic circuit, an ID corresponding to one personality of the plurality of personalities in response to the query ID command;
• and
• set the one personality as the selected personality in response to receiving a start session command from the host logic circuit and start the cryptographic session with the host logic circuit using the selected personality.
