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
