1. Does CC2420 support 6LOWPAN?  

2. Can the 6LOWPAN stack available in CONTIKI OS can be used with CC2420?

3. Does 6lowpan support is hardware specific

    CC2420 is a transceiver only. If you want run 6low pan , you need an extra host mcu. If you don't insist in using CC2420, I would suggest you using CC2538.

    Yikai,

    I concur with the previous post, if possible you should considder the CC2538. Its a single chip solution where there is a good well tested port of Contiki.

    But let me answer your orignal question:

    1. Does CC2420 support 6LOWPAN?  

    • The CC2420 is an 802.15.4 compatible transciever and it was one of the original drivers included in the Contiki system. So the answer is yes.

    2. Can the 6LOWPAN stack available in CONTIKI OS can be used with CC2420?

    • Yes, there are multiple "Motes" available in the market today that has a combination of MSP430+CC2420 where there exists a good port to Contiki.

    3. Does 6lowpan support is hardware specific

    • I am not sure I fully understand this question, but in general 6LoWPAN is a definition of how to transport IPV6 data over a low power lossy network. The stack and the definition is agnostic to what the actual physical layer is. That is, a Sub1GHz radio doing 50kbps is just a valid as a Zigbee (802.15.4) type radio is, it can even be PLC (Power line communication, it does not have to be wireless)
