Other Parts Discussed in Post: CC1101

Hey Champs, 

Before anything I am the Mktg mgr for the LPRF product line, which includes the new CC430 series of devices.

I just wanted to give you a heads-up on the recent progress made on the CC430 development tools. Here the picture of our first CC430 EM board that works in the 868Mhz and 915Mhz frequency bands. In brief it is a 4-layer board featuring the last version of our PCB (rev 3.0). It features a CC430F6xxx device with a bunch of connectors that are useful to extend the functionality of the hardware.

 

Compared to the CC1101 and CC1110 devices, they are a couple of new features which need to be highlighted.

1.   The first thing you can notice is the presence of the 14-pin JTAG connector on the top right of the board. This means that the CC430 EM board can be directly used as a target board for the MSP430 Flash Emulation Tools (or FET, see http://focus.ti.com/docs/toolsw/folders/print/msp-fet430uif.html). This means that the CC430 is a true JTAG based architecture. All the designers  who used proprietary emulation solution in the past will appreciate ! BTW I know that the LPRF tools team is working on a similar debugger, that should be released in 1st half… Stay tuned !

2.   The second interesting point is a located at the bottom of the board. If you have good eyes, you will see a string of passive components located between the CC430 and the antenna connector (there is no PCB antenna on this EM but you can hook-up a whip antenna). The reason for these passives devices is that the TI guys have changed the RF matching network they were using on the CC1101. The main difference is that the matching features a band-pass filter instead of a low-pass filter. This easy solution allows designers to get rid of the spurious emissions of the CC1101 radio @ 660Mhz and 699Mhz. The final outcome is that the matching is really optimized for maximum sensitivity (-110dBm @ 3V, 868Mhz and 1.2Kbps). Nice to see !

To close on this, attached the schematics of the band-pass filter that is used on the board…

Will tell you more when I progress with working with the board, talk to you soon !

Thanks, Emmanuel.

  • When will the CC430X parts be available?

    Thanks,

  • All,

    Sorry but I did not get any of the message that have been posted until today... the IT guys just fixed the issue.

    So... in short :

    - We do have a preliminary data-sheet for the CC430. It is not publically available as all the parameters of the data-sheet need to be characterized before the data-sheet can be posted on the TI web site. But you can get it from you local TI contact.

    - For the pricing it is hard to say as we will have a complete family of devices. But for 1Ku it ranges between $4 and $6

    - JTAG connector : sorry I screwed up. It is indeed on the top left corner of the picture

    - PCB antenna : we have not populated on on the first version of the board due to performance issues. But a future version will definitely have one.

    - 433Mhz version : still being discussed internally. I am confident we will have 433Mhz HW solutions available from TI or 3rd Parties

    - M-BUS : the german company AMBER-WIRELESS is working on it. You can contact Mr ESCH from http://www.amber-wireless.de/

    - Attachment : see under my post. the file is called CC430 EM RevC PG06 BPF update.pdf

    Hope this helps !

    Best, Emmanuel.

  • Got the kit. Is exactly what I have been looking for. Is there any CC430 specific wireless M-bus example code on the horizon?

  • I just received a set of these EVM boards. DerekC is correct, the JTAG is indeed top LEFT in the photo.

    The EVM is very funky - all the connectors are jammed up together. There's no RS-232 debug port; I guess it's a roll-your-own thing. I wish that there was a PCB trace antenna that you could select instead of the SMA.

    I would have preferred the EVM come with the non-LCD versions of the CC430, at least to start with, but that's me. The LCD feature makes it more complicated.

    When will there be a 433MHz version of this board available?

    Thanks,

    DerekS
