Protocol Selection
CryptoMemory supports two application areas with different communication protocols:
The power-up sequence of CryptoMemory determines what mode it shall operate in. A brief description of each of these
modes follows.
Synchronous Mode for Embedded Applications
The two-wire serial interface is used for fast and efficient communication with logic and controllers. The synchronous mode is
the default after powering up V
CryptoMemory in standard plastic packages RST is not bonded out and this is the only communication protocol.
Figure 7-1. Asynchronous Mode
CLK-SCL
The asynchronous mode is selected when RST is low on a rising edge of CLK. Once the asynchronous mode has been
selected, it is not possible to return to the synchronous mode other than by powering the device off and on again.
