Synchronous 2-wire Serial Interface
The synchronous mode is the default after powering up V
applications using CryptoMemory in standard plastic packages, this is the only communication protocol.
• Power-up V
• After stable V
Figure 11.
Note:
Communication Security Modes
Communications between the device and host operate in three basic modes. Standard mode is the default mode for
the device after power-up. Authentication mode is activated by a successful authentication sequence. Encryption mode
is activated by a successful encryption activation following a successful authentication.
