  • Forum Post: CC2570 Reference design

    Marko Pavlin75965
    Hi! I am looking for CC2570 reference design. There are schematics in datasheet SWRS095A without values. Is it possible to use reference design from similar product? Any suggestions? Thanks! Marko

  • Forum Post: Timing details on the CC2570/71 "SPI" interface?

    Mike Wirth
    I'm using a byte-synchronous connection between an MSP430F2274 and a CC2571, which is like SPI, with a few extra control lines. The timing diagram for this interface (Figs. 13 and 14 of the datasheet, SWRS095A, rev. March 2011) isn't very detailed (besides having the Figure titles reversed :...

    Peter Passow
    Hi, I am comparing the TI CC257x and the NS nRF24AP2 and discovered a significant difference in the amount of flash/ram requirements for the host processor. According to the "RF Connectivity with Microcontrollers" page on the TI website an MCU with no less than 128/256 kb flash and 8 kb...

    Reza Naima95461
    Hi all, I've looked through the datasheets on both TI's website and thisisant.com's website, but I can't find any specific requirements for either crystal. If it is documented someplace, can someone please provide a link? Otherwise, what are the requirements for the crystals? ...

    George Lin
    When I use ANTC7EK1 Evaluation Kit to be a Heart Rate Monitor transceiver. There are voltage drop( about 300~500 mV ) on battery voltage side. as this picture. If the battery (2032) is new, the situation is better. I try to put 100uF capacitor x2 ,but it still have same situation. We change...

  • Forum Post: RE: ANT Continuous-Scanning channel - Collisions?

    Harrison
    Hi Ragnar, I would recommend looking up the ANT Basics video describing ANT's built-in Isochronous Ad-hoc Time-Adaptive Multiplexing scheme which you can find at the thisisant.com website under presentations but I will try to summarize here. An ANT Master channel breaks an RF space into "timeslots"...

  • Forum Post: RE: ANT Continuous-Scanning channel - Collisions?

    Harrison
    Hi, just to provide some additional clarifications. No need to worry about intermittent transmissions, ANT master channels by default take a brief receive window to find an open timeslot before broadcasting, so they do have some measure of avoiding each other even as they start transmitting. In a...

    Harrison
    Hi, The CC2570/71 is a network processor only which is why information such as flash or RAM is not available, and at the moment TI does not yet offer an ANT System on Chip . The lowest power mode on the CC257x is Powered Down Sleep, so the sleep mode current is 0.5uA. In-between ANT messages on a...

    Hi, You can find TI's reference for the CC2570/CC2571 right on their respective product page here , it's also Gerber files + Cadstar. There's also footprints for a handful of formats including Altium. Cheers!
