ATA5811/ATA5812 [Preliminary]
The supply voltage range is 4.4 V to 6.6 V and VAUX is connected to an inductive
supply.

The microcontroller interface is a level converter which converts all internal digital sig-
nals which are referred to the DVCC voltage, into the voltage used by the
microcontroller. Therefore, the pin VSINT has to be connected to the supply voltage of
the microcontroller.
This makes it possible to use the internal voltage regulator/switch at pin VSOUT as in
Figure 4 on page 6 and Figure 6 on page 8 or to connect the microcontroller and the pin
VSINT directly to the supply voltage of the microcontroller as in Figure 5 on page 7.
The configuration of the transceiver is stored in RAM cells. The RAM contains a
16
via a 4-wire serial interface (CS, SCK, SDI_TMDI, SDO_TMDO).
The 1
interface.
The RAM and the status information is stored as long as the transceiver is in any active
mode (DVCC = VS1 or DVCC = V_REG2) and gets lost if the transceiver is in OFF
mode (DVCC = OFF).
