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).

•

Excellent

receiver

sensitivity

and

robustness to interferers

•

128 KB in-system programmable flash

•

8 KB RAM, 4 KB with data retention in

all power modes

•

Powerful DMA functionality

•

Very few external components

•

Only a single crystal needed for mesh

network systems

•

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
