I put together a Zigbee/802.15.4 chip comparison guide. There is another one up on the web , but it hasn't been updated since 2004. I thought I would put together the 2008 version since a lot of the info on the 2004 chart is a bit obsolete. Such as:
- The AT86RF210 is EOL'd
- CompXS was purchased by Integrated
- Ember's EM2420 was a re-marked CC2420 which disappeared after TI purchased Chipcon
- ZMD no longer makes their Zigbee chip. I think they cut some deal with Renesas which gave them the IP
The second comparison table is for integrated MCUs + Transceivers. The integrated category is quite complex and I might expand this one later. Integrating an MCU and a radio is difficult because many features come into play: ADC, ADC Resolution, number of timers, types of timers, GPIO, development tools, architecture, etc... I might need to make a more comprehensive list, but here is the first stab at it. Regarding the power consumption values, in cases where a multi-chip module are used (they just stuck an MCU and a radio die on the same substrate), the power values are given as separate MCU and RF numbers since I couldn't get the actual total consumption value. If anyone can correct me on these, please let me know...
In case these images are too small, I've made the PDF available here as well as an easy pdf download link at the bottom of this page. If you find any mistakes or if I left out anything significant, please feel free to drop me an email or leave a comment or send me a private message (see, there is some benefit to being registered) or post on the discussion forum or instant message me. Just kidding. I don't like instant messaging much.
Updated 2008-12-05: Added AT86RF231 and MC13224 chips to the chip comparison guide.
Updated 2008-12-12: Fixed to include the Microchip MRF24J40 and the Radiopulse MG2400. These were cut off by the margins on the PDF utility.
