Note:
1. 5V tolerant input considerations when operating from 3.3V:
When the XRT8001 is powered at 3.3V, it can tolerate 5V-level signals via its inputs. However, the user should be aware the XRT8001
contains a “Factory-Test” Mode. This mode is enabled whenever the MSB (Master-Slave select) input pin is pulled to about 2V above
VDD.
Therefore, if the user is powering the XRT8001 at 3.3V but is applying a 5.25V signal to the MSB input pin, then it is possible that the
XRT8001 could be configured to operate in this “Factory-Test” Mode. Since all “Factory-Test” Mode registers are reset to “0”, upon
chip power, this should not be a problem for the user.
However, if the user performs write operations to “non-defined” address locations within the XRT8001, then the user may observe strange
operation from the XRT8001. The user must make sure that when the Microcontroller performs WRITE operations to the XRT8001, it
is only performing these WRITE operations to the Address Locations defined in the XRT8001 Data Sheet.
