ATA5823/ATA5824
The supply voltage range of the ATA5823/ATA5824 is 2.15V to 3.6V or 4.4V to 5.25V.
Pin VS1 is the supply voltage input for the range 2.15V to 3.6V and is used in battery applica-
tions using a single lithium 3V cell. Pin VS2 is the voltage input for the range 4.4V to 5.25V (car
applications), in this case the voltage regulator V_REG regulates VS1 to typically 3.25V. If the
voltage regulator is active, a blocking capacitor of 2.2 µF has to be connected to VS1.
Pin VSINT is the voltage input for the Microcontroller_Interface and must be connected to the
power supply of the microcontroller. The voltage range of V
10-5
AVCC is the internal operation voltage of the RF transceiver and is feed via the switch
SW_AVCC by VS1. AVCC must be blocked on pin AVCC with a 68 nF capacitor (see
on page
DVCC is the internal operation voltage of the digital control logic and is fed via the switch
SW_DVCC by VS1. DVCC must be blocked on pin DVCC with 68 nF (see
Figure 4-1 on page
Pin PWR_ON is an input to switch on the transceiver (active high).
Pin N_PWR_ON is an input for a push button and can also be used to switch on the transceiver
(active low).
For current consumption reasons it is recommended to set N_PWR_ON to GND only tempo-
rarily. Otherwise an additional current flows because of a 50 k pull-up resistor.
A voltage monitor generates the signal DVCC_OK if DVCC
