• Manufacturer Part Number: xe1202
• Description: Low-power, Integrated Uhf Transceiver
• Manufacturer: ETC-unknow

The XE1202 single-chip solution is an integrated circuit intended for use as a low cost FSK transceiver to establish
a frequency-agile, half-duplex, bi-directional RF link, with non-return to zero data coding. The device is available in
an LQFP44 package and is designed to provide a fully functional multi-channel FSK transceiver. It is intended for
applications in the 433- and 868MHz European band and the North American 902-928MHz ISM band. The single
chip transceiver operates down to 2.7 V and provides low power consumption solutions for battery-operated and
power sensitive applications. Thanks to the low external components count, the XE1202 is ideal for small size, low-
cost UHF links. Its reference board design has no tunable components, which facilitates high volume cost sensitive
production.
The XE1202 can easily be interfaced to a controller such as the XEMICS’ XE8000 Series of ultra low-power
microcontrollers. The XE1202 serial control registers are programmed by the MCU and the MCU manages the
communication protocol.
