Figure 15. Isolated SPI pulse shape and logical meaning
3.4.4.1
ISO communicator receiver and transmitter
An isolated receiver and transmitter are connected to the couple of pins and ISOP/M. Depending on the
communication phase, they can be enabled or disabled.
3.4.4.1.1
ISO communicator receiver
The receiver is able to convert a differential input signal into a single ended signal that is provided to the logic:
•
While in Normal state, in order to guarantee a correct communication, the input common mode must stand
within VCM_ISO_IN limits.
•
When in Stand-by state, the ISOP and ISOM pins are not biased with a common mode. If the device
receives a series of differential pulses longer than NMIN_ISO_WAKEUP_EDGES, a wake up condition is
triggered. Pulse amplitude must be higher than Wakeup_thr in order to be counted.
3.4.4.1.1.1
Electrical parameters - ISO receiver
All parameters are tested and guaranteed in the following conditions, unless otherwise specified: 4.5 V ≤ VVDD ≤
5.5 V ; -40 °C < Tambient < 105 °C
