XE1202A TrueRF™
433 MHz / 868 MHz / 915 MHz
Low-Power, Integrated UHF Transceiver
GENERAL DESCRIPTION
The XE1202A TrueRF™ is a single chip transceiver
operating in the 433, 868 and 915 MHz license free
ISM (Industry Scientific and Medical) frequency
bands. Its highly integrated architecture allows for
minimum external components while maintaining
design flexibility. All major RF communication
parameters are programmable and most of them can
be dynamically set. The XE1202A TrueRF™ offers a
wide range of channel bandwidths, without the need
to modify the number or parameters of the external
components. The XE1202A TrueRF™ is optimized for
low power consumption whilst offering high RF output
power and channelized operation suitable for both the
European (ETSI-300-220) and the North American
(FCC part 15) regulatory standards.
APPLICATIONS
Security systems
Voice and data over an RF link
Process and building control
Access control
Home automation
Home appliances interconnection
