Just would like to know, when jumping from one RF chip to another,if my layout, antenna,matching circuit are identical then would I notice a differnce in performance of my RF signal? I know that RF is 1db more powerful, so I guess I would get a extra transmission differnce with my current design? I urge you to not do RF design at the chip level. Start with a module, as sold by Atmel, Digi International, Anaren, and many others. Has antenna on PCB or antenna connector.

I currently looking to integrate the RF transceiver from Atmel in one of my design and I just wonder if someone have something to tell about it.
Is the chip follow the spec given by Atmel sensitivity, timing, etc? Is there a lot of bugs with the chips? TinyOS - Help. Search everywhere only in this topic. Advanced Search. Classic List Threaded. Frederic Beaulieu Atmel RF Giri Baleri. Re: Atmel RF Hi Fred,. You can find product details at.
I hope that helps,. Miklos Maroti. In reply to this post by Frederic Beaulieu I cannot verify the sensitivity, but the published timings to control the state machine of the radio chip is correct. The basic operation mode works as advertised. The automatic mode had several errors and lack of configuration options that prevented the tinyos 2. Nonetheless, the basic mode is perfectly appropriate to do everything at least as good as the cc driver does.
We can send a software generated acknowledgement frame in less than microsecond. The chip has a new revision and corrects most of the early problems of the first revision. However I did not investigate if the automatic mode would be useful. Also, the original revision does not have an automatic CRC check for the received packets in the basic mode, this is corrected in the new revision. I have observed that under very rare circumstances in a 1 microsecond window , that the chip can get stuck between the receive state and transmit state.
I cannot really compare. I think the programming interface of the chip is simpler than that of the CC Thanks for your input! When you are talking about the new chip revision, do you talk about the rf??? Can you be more explicit about the "several errors and lack of configuration options" of the automatic modes?
