CC1110Fx / CC1111Fx
The high speed crystal oscillator must
be used when the radio is active.
Typically used to connect to external
DAC or ADC
Clock source for ultra-low power
operation can be either a low-power RC
oscillator or an optional 32.768 kHz
crystal oscillator
2.5 Hardware AES Encryption/Decryption
128-bit AES supported in hardware
coprocessor
Very fast transition to active mode from
power modes enables ultra low average
power consumption in low duty-cycle
systems
2.6 Peripheral Features
Powerful DMA Controller
Power On Reset/Brown-Out Detection
2.8 Sub-1 GHz Radio with Baseband
Modem
ADC with eight individual input
channels, single-ended or differential
(CC1111Fx has six channels) and
configurable resolution
Based on the industry leading CC1101
radio core
Few external components: On-chip
frequency synthesizer, no external filters
or RF switch needed
Programmable watchdog timer
Five timers: one general 16-bit timer
with DSM mode, two general 8-bit
timers, one MAC timer, and one sleep
timer
Flexible support for packet oriented
systems: On-chip support for sync word
detection, address check, flexible
packet length, and automatic CRC
handling
Two
programmable
USARTs
for
master/slave SPI or UART operation
21 configurable general-purpose digital
I/O-pins (CC1111Fx has 19)
Supports use of DMA for both RX and
TX
resulting
in
minimal
CPU
intervention even on high data rates
Random number generator
Programmable channel filter bandwidth
2.7 Low Power
2-FSK, GFSK, MSK, ASK, and OOK
modulation formats supported
Four flexible power modes for reduced
power consumption
Optional automatic whitening and de-
whitening of data
System can wake up on external
interrupt or when the Sleep Timer
expires
Programmable Carrier Sense (CS)
indicator
0.5 µA current consumption in PM2,
where external interrupts or the Sleep
Timer can wake up the system
Programmable
Preamble
Quality
Indicator (PQI) for detecting preambles
and improved protection against sync
word detection in random noise
0.3 µA current consumption in PM3,
where external interrupts can wake up
the system
Support for automatic Clear Channel
Assessment (CCA) before transmitting
(for listen-before-talk systems)
Low-power fully static CMOS design
Support for per-package Link Quality
Indication (LQI)
System clock source is either a high
speed crystal oscillator (26 - 27 MHz for
CC1110Fx and 48 MHz for CC1111Fx) or a
high speed RC oscillator (13 - 13.5 MHz
for CC1110Fx and 12 MHz for CC1111Fx).
