Product Description
The CC2431 is a true System-On-Chip (SOC)
for wireless sensor networking ZigBee™ /
802.15.4 solutions with location detection
engine hardware onboard allowing location
accuracy of around 3 meters or less. It
enables ZigBee™ nodes to be built with very
low total bill-of-material costs. The CC2431
combines the excellent performance of the
leading CC2420 RF transceiver with an
industry-standard enhanced 8051 MCU, 128
KB flash memory, 8 KB RAM and many other
powerful features. Combined with the industry
leading ZigBee™ protocol stack (Z-Stack™)
from Figure 8 Wireless / Chipcon, the CC2431
provides the market’s most competitive
ZigBee™ solution.
The CC2431 is highly suited for systems where
ultra low power consumption is required. This
is achieved by various operating modes. Short
transition times between these modes further
ensure low power consumption.
Key Features
•
•
•
Location Engine accurately calculates the
location of a node in a network
High performance and low power 8051
microcontroller core.
2.4 GHz IEEE 802.15.4 compliant RF
transceiver (industry leading CC2420 radio
core).
•
•
Low current consumption (RX: 27mA, TX:
25mA, microcontroller running at 32 MHz)
Only 0.9µA current consumption in power-
down mode, where external interrupts or
the RTC can wake up the system
Less than 0.6µA current consumption in
stand-by mode, where external interrupts
can wake up the system
Very fast transition times from low-power
modes to active mode enables ultra low
average power consumption in low duty-
cycle systems
