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
