Hello,
I've searched a long time detailed specfications on BL6450 (BlueLink 7.0) chip and only get below pdf :

Does this chip exist as a standalone component or is it compulsory embedded in other chip as NL5500 ?
Is there a way to get in touch with the relevant person at TI's able to provide me with detailed specs, availability informations, contact for pricing and samples buying.
Thanks in advance for your great help.
Best regards,
Arnaud
