Connections and Optional External Components
Power Connections (VDD)
The CYBLE-0130XX-00 contains one power supply connection, VDD.
VDD accepts a supply input range of 2.3V to 3.6 V.
provides this specification. The maximum power supply ripple for this
power connection is 100 mV, as shown in
External Reset (XRES)
The CYBLE-0130XX-00 has an integrated power-on reset circuit which completely resets all circuits to a known power on state. This
action can also be driven by an external reset signal, which can be used to externally control the device, forcing it into a power-on
reset state. The XRES signal is an active-low signal, which is an input to the CYBLE-0130XX-00 module.
External Component Recommendation
Power Supply Circuitry
It is not required to place any power supply decoupling or noise reduction circuitry on the host PCB. If desired, an external ferrite bead
between the supply and the module connection can be included, but is not necessary. If used, the ferrite bead should be positioned
as close as possible to the module pin connection.
If used, the recommended ferrite bead value is 330
Ω
