Product Description
The
CC2500
is
a low
-
cost 2.4 GHz transceiver
designed for very low
-
power wireless appli
-
cations. The circuit is intended for the
2400
-
2483.5 MHz
ISM (Industrial, Scientific and
Medical) and SRD (Short
Range Device)
frequency band
.
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 500
kBaud
.
CC2500
provides extensive hardware support
for packet handling, data buffering, burst
transmissions, clear channel asses
sment, link
quality indication
,
and wake
-
on
-
radio.
The main operating parameters and the 64
-
byte transmit/receive FIFOs of
CC2500
can be
controlled via an SPI interface. In a typical
system, the
CC2500
will be used together with
a micro
controller and a f
ew additional passive
components.
