DSP56301 BSDL for revision 1F48S

mjd_bishop — Tue, 22 Apr 2025 14:36:26 GMT

I'm working on a vintage design / hardware, from the 1990's using DSP56301

The JTAG scan chain works, the correct BSDL file is what I require to educate the software

Hello @mjd_bishop ,

Thanks for you post. It's such an old product. I only find IBIS file for it.

However, you can go to the website and try to request the file:
Microcontroller Symbols, Footprints and Models | NXP Semiconductors

Hope it can help you.

BRs,

Celeste

Thank you for the IBIS file
As suggested, I have requested a BSDL file
Let us see if that resolves the issue

Hello @mjd_bishop ,

I can find the BSDL for DSP56301 on the Search | NXP Semiconductors. What's your model? You can find it through the search function on the official website of NXP.

Hi @Celeste_Liu

Thank you for the pointer - I have downloaded BSDL for 56301 rev A B C for 208 tqfp

The next issue is which BSDL file corresponds to a 1F48S device revision

With a suplementary question of where this information is tabulated, not on the silicon Errata sheet

Best Regards

Martin

Hello @mjd_bishop ,

According to my understanding,

I don't think there is a strong correlation between the bsdl file and the chip mask. A new revision will only be issued when we find problems with the bsdl. Eg,

Therefore, I think you should refer to Rev C.

Hope it can help you.
