CC2540 single-mode SoC capable of running both protocol stack?

Other Parts Discussed in Thread: CC2540, CC2564, CC2560, CC2567

Hello,

i found the information that the CC2540 support both protocol stack. The link with this information is below

http://newscenter.ti.com/Blogs/newsroom/archive/2010/07/06/texas-instruments-continues-to-lead-bluetooth-174-low-energy-technology-advancements-452287.aspx

now, i'm just trying to find out how to implemt the Bluetooth stack on the cc2540, but i can't find any information.

If the CC2540 support both protocol stacks, it must be also possible to connect the CC2540 with Bluetooth devices with lower version than Bluetooth 4.0.

Best regards

Andreas

    Hi Andreas,

    I think you have misunderstood the press release. We are not claiming to be able to run both LE and Bluetooth BR/EDR protocol stacks on CC2540. We support both dual- and single-mode, but dual-mode requires different ICs (CC2560, CC2564, CC2567).

    The CC2540 does not support the BR and EDR modulation formats and packet formats. If we had designed it to be compatible with BR/EDR, then it would have been higher power and cost more. The whole reason Bluetooth accepted that BLE would not be backwards-compatible is that this allowed improvements in power and cost that could not be realized in dual-mode devices.

    Hi 

    I am looking for SOC that will be cable to support Blue tooth 2.1 such like the CC2540?

    Is anyone know if there is an IC like that ?

    Hi,

    I am not aware of any flash-based classic Bluetooth SoCs, no.

    Most Bluetooth ICs are HCI-level ones, like CC2560 and CC2564. There are a few more SoC-like chips for things like headsets or keyboards, but these generally require external memory and are pretty specialized for the targeted application.

    Best regards,
