Serial Data Out pin. In SPI communication mode this pin functions as the serial data output. In TWI communication
mode this pin is not used.
SPI Slave Select Bar input pin. In SPI communication mode this pin functions as the slave select input. In TWI
communication mode this pin is not used and should be connected to V
RF Pin Descriptions
Antenna driver. The 13.56 MHz carrier frequency is generated by ANT and is shaped into a sine wave by external
passive circuitry.
C6 Antenna bypass capacitor pin. The C6 pin provides power to the antenna circuits and modulates the power level for
communications.
RF input pin. RFin is the input to the receiver. A resistor/capacitor filter is used to limit the peak to peak voltage on this
pin to a safe level. See the AT88RF1354 reference design for appropriate component values.
Analog Pin Descriptions
C1 bypass capacitor pin. Bypass capacitance of 0.33 uF for the digital circuits must be connected between the C1 pin
and V
dielectric and a working voltage of 10 volts minimum may be used.
C2 bypass capacitor pin. Bypass capacitance of 47 nF for the analog circuits must be connected between the C2 pin
and V
dielectric and a working voltage of 10 volts minimum may be used.
C3 bypass capacitor pin. Bypass capacitance of 47 nF for the analog circuits must be connected between the C3 pin
and V
dielectric and a working voltage of 10 volts minimum may be used.
C4 bypass capacitor pin. Bypass capacitance of 0.33 uF for the analog circuits must be connected between the C4 pin
and V
dielectric and a working voltage of 10 volts minimum may be used.
C5 bypass capacitor pin. Bypass capacitance of 0.33 uF for the digital circuits must be connected between the C5 pin
and V
dielectric and a working voltage of 10 volts minimum may be used.
