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.
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.

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

Reduced Battery Current using
TPS62730
The
TPS62730
[26] is a step down
converter with bypass mode for ultra low
power wireless applications.
In RX, the current drawn from a 3.6 V
battery is typically less than 11 mA when
TPS62730
output voltage is 2.1 V. When
connecting
CC1101
directly to a 3.6 V
battery the current drawn is typically 17
mA (see Figure 1)
In TX, at maximum output power (+12
dBm), the current drawn from a 3.6 V
battery is typically 22 mA when
TPS62730
output voltage is 2.1 V. When connecting
CC1101
directly to a 3.6 V battery the
current drawn is typically 34 mA (see
Figure 2).
When
CC1101
enters SLEEP mode, the
TPS62730
can be put in bypass mode for
very low power down current
The typical
TPS62730
current consumption
is 30 nA in bypass mode.
The
CC1101
is connected to the battery via
an integrated 2.1 Ω (typical) switch in
bypass mode
