Key Features

? Location Engine 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).

? ZigBee? protocol stack (Z-Stack?) from

Texas Instruments includes support for CC2431

‘s location engine.

? 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: 27 mA, TX: 27

mA, microcontroller running at 32 MHz)

? Only 0.5μA current consumption in powerdown

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
