Hi all!
I have seen that TI recommends to interface its CC2520 modules to MSP430F5438
and MSP430F2618 (at least that's what I saw on TI's web page). I was
wondering why couldn't I interface these zigbee modules to other MSP430
MCU's such as MSP430G2553? I read that cc2520 modules can communicate with
the above mentioned MCU's via SPI, and can even be configured this way.
Could somebody explain me that? I will appreciate it, indeed.
Thanks,
Javier

Not necessarily. The below links to a library using the Launchpad:

Hi Yagui,
To get the most out of zigbee you are going to need a fairly large chip,
in the ram and Flash section, to load the library and whatever else you
want to do with it.

One word...
Stack.
The G2xx series only has 16K flash at most. A minimalist ZigBee stack would still be too much. The smallest CC2530 (the SoC device) has 32K of flash. That is enough to flash the most minimalist stack you can think of and have maybe a little room for some application software.
If you really want to use a G2xx, use something like a CC110L. There's a wireless boosterpack called the CC430BOOST-110L for like 20 bucks which just connects cleanly to the Launchpad headers. Granted, it isn't ZigBee but if you're doing point to point and don't need to set up a mesh, this will work fine.

I've written a small tutorial on the using CC110l with msp430g2553
