Product Description

CC1101 is a low-cost sub-1 GHz transceiver

designed for very low-power wireless applications.

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.

Assessment (CCA) before transmitting (for

listen-before-talk systems)

 Support for per-package Link Quality

Indication (LQI)

 Optional automatic whitening and dewhitening

of data

Low-Power Features

 200 nA sleep mode current consumption

 Fast startup time; 240 μs from sleep to RX

or TX mode (measured on EM reference

design [1] and [2])

 Wake-on-radio functionality for automatic

low-power RX polling

 Separate 64-byte RX and TX data FIFOs

(enables burst mode data transmission)

General

 Few external components; Completely onchip

frequency synthesizer, no external

filters or RF switch needed

 Green package: RoHS compliant and no

antimony or bromine

 Small size (QLP 4x4 mm package, 20

pins)

 Suited for systems targeting compliance

with EN 300 220 (Europe) and FCC CFR

Part 15 (US)

 Suited for systems targeting compliance

with the Wireless MBUS standard

EN 13757-4:2005

 Support for asynchronous and

synchronous serial receive/transmit mode

for backwards compatibility with existing

radio communication protocols

Improved Range using CC1190

 The CC1190 [21] is a range extender for

850-950 MHz and is an ideal fit for CC1101

to enhance RF performance

1% packet error rate

o -120 dBm at 1.2 kBaud, 915 MHz,

1% packet error rate

 +20 dBm output power at 868 MHz

 +27 dBm output power at 915 MHz
