The difference between CC2520 and CC2480

Other Parts Discussed in Thread: CC2520, Z-STACK

I'm now constructing a Zigbee package using MSP430 and CC2520 or CC2480. I found some data about these two chips. CC2480 is called Zigbee processor, and CC2520 is TI's second generation ZigBee RF transceiver. But I don't know the exact difference between these two when working in the Zigbee network. I know the Pins and functions are similar for these two chips, but there must be some difference with connection between the CC2XXX and the MSP430.

In addition, I know in the development kit of eZ430-RF2480, Z-Accel concept is applied, while in the DK of CC2520 they apply Z-stack concept. I want to know the difference between these two concepts.

Thanks.

    Both kits use Z-stack. However the CC2520 supports the newer version of the Z-Stack which is based on the Zigbee 2007 PRO standard, whereas the CC2480 supports the older version of Z-Stack which is based on the Zigbee 2006 standard.

    Hi recursive

    Thanks for your reply.

    But I'm still wandering if you know the difference between the two chips when working in the Zigbee network? For example the transmission distance of the RF signal, the intensity of the signal or the processing speed of the digital signal with the MSP.

    Thanks
