CC1100
Low-Power Sub- 1 GHz RF Transceiver

Applications
• Ultra low-power wireless applications
operating in the 315/433/868/915 MHz
ISM/SRD bands
• Wireless alarm and security systems
• Industrial monitoring and control
• Wireless sensor networks
• AMR – Automatic Meter Reading
• Home and building automation

Product Description
The CC1100 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, 400-464 MHz and 800-928 MHz bands.
The RF transceiver is integrated with a highly
configurable baseband modem. The modem
supports various modulation formats and has
a configurable data up to 500 kBaud.
CC1100 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 CC1100 can be
controlled via an SPI interface. In a typical
system, the CC1100 will be used together with a
microcontroller and a few additional passive
components.

Key Features
RF Performance
• High sensitivity (–111 dBm at 1.2 kBaud,
868 MHz, 1% packet error rate)
• Low current consumption (14.4 mA in RX,
1.2 kBaud, 868 MHz)
• Programmable output power up to +10
dBm for all supported frequencies
• Excellent receiver selectivity and blocking
performance
• Programmable data rate from 1.2 to 500
kBaud
• Frequency bands: 300-348 MHz, 400-464
MHz and 800-928 MHz
Analog Features
• 2-FSK, GFSK, and MSK supported as
well as OOK and flexible ASK shaping
• Suitable for frequency hopping systems
due to a fast settling frequency
synthesizer: 90us settling time
• Automatic Frequency Compensation
(AFC) can be used to align the frequency
synthesizer to the received centre
frequency
• Integrated analog temperature sensor
Digital Features
• Flexible support for packet oriented
systems: On-chip support for sync word
detection, address check, flexible packet
length, and automatic CRC handling
• Efficient SPI interface: All registers can be
programmed with one “burst” transfer
• Digital RSSI output
• Programmable channel filter bandwidth
• Programmable Carrier Sense (CS)
indicator
• Programmable Preamble Quality Indicator
(PQI) for improved protection against
false sync word detection in random noise
• Support for automatic Clear Channel
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
• 400nA SLEEP mode current consumption
• Fast startup time: 240us from sleep to RX
or TX mode (measured on EM reference
design [5] and [6])
• 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).
• Support for asynchronous and
synchronous serial receive/transmit mode
for backwards compatibility with existing
radio communication protocols
