TMS320VC5509A: Hello,Customer purchased a batch of TMS320VC5509APGE chips from Rochester Electronics. On this circuits marking $. What this means?

The information on the 3^rd row in the picture is traceability information.

We do not provide a decoder for all the characters.

The first A is the product die revision character.

Hi Egor,

As mentioned by Arnon, whole 3rd row is used for traceability and $ within that is just one character. Hope this helps.

Regards,

Prasad
