DESCRIPTION
The RFW122-L ISM transceiver module is a short-
range wireless radio transceiver. The transceiver is
intended for use in the world wide unlicensed Indus-
trial, Scientific and Medical (ISM) band of 2400-2483.5
MHz, complying with world wide regulations and stan-
dards. The module core consists of 2 chips, offering
small size, low power consumption and simple inter-
gration with applications. The module includes a
printed antenna which is matched to 200 Ω differential
input impedance. The module has a simple six pin
interface, which includes 3 digital control lines. The

FEATURES
APPLICATIONS
• Home automation and security
• Industrial automation
• Peripherals: keyboards, mice, gamepads
• Remote control devices
• Toys and games
data I/O line is a simple serial interface. During
standby, the transceiver consumes almost no power
(0.1 μA at V
time of 20 μs. The signal acquisition time is only 1.2 μs.
This results in an efficient power consumption man-
agement method, by using the standby mode in a fre-
quent manner. The communication link between the
transceivers is a Unique Direct Sequence Spread
Spectrum (DSSS) pulse pipe. The modulation scheme
is 100 % Amplitude Shift Keying (ASK).
• Designed for short range wireless communication
• Data rate - up to 1 Mb per second
• Simple 3 line digital interface
• Low power consumption - ideal for battery operated
• + 7 dBm typical peak output transmission power
• - 75 dBm typical sensitivity
• Complies with FCC regulations
• Wide range operating voltage (2.6 - 3.5 V)
• Unique Direct Sequence Spread Spectrum Code
• Short signal acquisition time (1.2 μs)
in the 2.4 GHz - world wide license free band
