Product Description
CC1101 is a low-cost sub-1 GHz transceiver
designed for very low-power wireless appli-
cations. The circuit is mainly intended for the
ISM (Industrial, Scientific and Medical) and
SRD (Short Range Device) frequency bands
at 315, 433, 868, and 915 MHz, but can easily
be programmed for operation at other
frequencies in the 300-348 MHz, 387-464 MHz
and 779-928 MHz bands.
The RF transceiver is integrated with a highly
configurable baseband modem. The modem
supports various modulation formats and has
a configurable data rate up to 600 kbps.
CC1101 provides extensive hardware support
for packet handling, data buffering, burst
transmissions, clear channel assessment, link
quality indication, and wake-on-radio.
The main operating parameters and the 64-
byte transmit/receive FIFOs of CC1101 can be
controlled via an SPI interface. In a typical
system, the CC1101 will be used together with a
microcontroller and a few additional passive
components.
The CC1190 850-950 MHz range extender [21]
can be used with CC1101 in long range
applications for improved sensitivity and higher
output power.
