Product Description
The
CC2431
is a true System-On-Chip (SOC)
for wireless sensor networking ZigBee
®
/IEEE
802.15.4 solutions. The chip includes a
location detection hardware module that can
be used in so-called blind nodes (i.e. nodes
with unknown location) to receive signals from
nodes with known location’s. Based on this the
location engine calculates an estimate of a
blind node’s position. The
CC2431
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 Texas
Instruments, 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.

Low current consumption (RX: 27 mA, TX: 27
mA, microcontroller running at 32 MHz)
Only 0.5µA current consumption in power-
down mode, where external interrupts or the
RTC can wake up the system
0.3 µA current consumption in power-down
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
CSMA/CA hardware support
Wide supply voltage range (2.0 V – 3.6 V)
Digital RSSI/ LQI support
Battery monitor and temperature sensor
ADC with up to eight inputs and configurable
resolution
128-bit AES security coprocessor
