Cypress Semiconductor CYRF9935
CYRF9935
General Description
CYRF9935 is a low power radio transceiver operating in the
world wide 2.4–2.5 GHz ISM band. The transceiver contains fully
integrated receiver, transmitter, frequency synthesizer and
baseband engine. Internal voltage regulators ensure good
immunity to power supply noise and wide power supply voltage
range.
CYRF9935 offers a high data rate of 2 Mbps. It enables burst
transmission to reduce the average power consumption. In
addition, the built-in automatic acknowledgement, automatic
re-send and low power consumption in Idle-I mode, are very
useful features for low power wireless applications.
