Notes
[1]. Typically data modes with high chip encoding which provides a higher process gain and lower data rates provide longer range and / or a more
robust wireless link.
[2]. This mode is compatible with Cypress Generation 1 RF WirelessUSB transceiver devices, CYWUSB6934 and CYWUSB6935.
[3]. It is permissible to connect voltages above V
IO
to inputs through a series resistor limiting input current to 1 mA. AC timing not guaranteed.
[4]. Human Body Model (HBM).
