How about using Integration's ML7065 it has a complete 802.15.4 MAC implementation where as my understanding is that Airbee and Ember if using the CC2420 (or EM2420) have implemented part of the MAC layer into their software stack on the micro which does have an impact on code/data space available. I do not know what footprint does the Airbee implementation carries and what are your application's requirements. So, get the part with most ram/flash, the F13x and F14x family are possible candidates.
Making something custom is entirely your choice but If you are only looking for a module which gives you zigbee connectivity then Telegesis's ETRX1 or ETRX2 which are based on AVR/CC2420/EM250 and Ember zigbee stack and comes with two serial ports and number of I/O pins in a convenient form factor can also be used to provide your application zigbee compatibility. It will save you the hassle of doing 2.4GHz RF design.

Hi all, I'm switching my tooling from AVR to MSP. I'd like to make some CC2420 ZigBee/MSP modules (think AirBee-light MSP430 demo), and I'm wondering which MSP variant folks would suggest. Design criteria, in order of importance: * Small (QFN package) * 1.8V operation * SPI (obviously, for CC2420) * Uart, 38.4k operation w/o crystal preferred * >4 GPIO's * I2C * Adc Also, what solution is suggested for flash programming & debug (can be two items)? Usb prefered, 802.3 ok too? Has MSP standardized on a connector and pinout for prog/debug? Anybody want to buy a couple boards when I do a run? I'm planning a 24-pin extra-wide (0.9") DIP format so we can stick it into proto boards directly, and a carrier with some screw-terminals, gpio buffers, some solid-state relays . Thanks for the info! Steve
