OM5578/PN7150ARD is
How can I get it?

Discontinuation Notification 202001024DN

Why was PN7150B0HN / C11004E discontinued?

[IvanRuiz]

Hello,

Yes, I just received internal feedback about this. They let me know that we had to discontinue this version because of a major regression lately found.

We are planning to release a new version fixing this but are still waiting for R&D planning for which we will appreciate your comprehension on this.

Thank you very much.

BR,

Ivan.

[IvanRuiz]

Hello,

Please let me know if I understood your requirement.

When you try to read ICODE SLIX 1 & 2 specifically it is not possible to activate them? If so, have you modified something in the SW to detect multiple devices?

Thank you for clarifying.

BR,

Ivan.

Hello

Thank you for your reply

Yet I have not changed the settings
The same execution environment

[Anti-collision failure]

  UID = e0 04 01 50 65 6c 74 0f
  UID = e0 04 01 50 65 6c e9 df

[Anti-collision success]

  UID = e0 04 01 50 d6 bb 63 76
  UID = e0 04 01 50 d6 bb 63 09

After this, I want to change the PF_BIT_RATE setting.
Are there any other measures?

[h-kawada]

> After this, I want to change the PF_BIT_RATE setting.

Changing PF_BIT_RATE did not change the result

  Tried value :
    0x00 : 106k
    0x01 : 212k
    0x02 : 424k
    0x03 : 848k
    0x80 : 26k
    0x81 : 212k & 424k
