Requesting for details of the ibis models/components for F280049RSHSR / sprm689.ibis

Abhishekh M L

Hi Team,

I was working on a Piccolo uC from TI. Part# - F280049RSHSR

I see inside ibis model there are various components/models and for which the explanation/definition I could not get in datasheet/ website.

IQ0440FS_VREGENZ_USF

BT3308BT5FSHYPB_SFII

Can you please help me to get those details (maybe from your technical team) ? so it helps in my simulation activity

Thanks and regards,

Hi Peter,

Thanks for your response.

I do have the ibis model downloaded. Sprm689.ibis

Please refer to thread where I've asked about the devices/models inside and definition/explanation for them on how to be used...

IQ0440FS_VREGENZ_USF

BT3308BT5FSHYPB_SFII

Thanks and appreciate people helping me on this

Abhishekh,

The question isn't clear to me. The IQ0040 cell is the input model for the VREGENZ pin. The BT3308 model is for the pins:

GPIO16

GPIO17

GPIO24

GPIO25

GPIO26

GPIO27

GPIO37/TDO

GPIO35/TDI

GPIO41

GPIO42

GPIO43

GPIO40

This connectivity can be seen in the model assignment for pins. IBIS is used at the PCB level simulation to check signal integrity. See these resources:

Best regards,

Abhishekh,

I just heard from our design team that they will provide additional details to your question by this Friday.

Abhishekh,

Below is the description of the two buffers:

IQ0440FS_VREGENZ_USF

>> Input buffer used for internal VREG enable/disable.

BT3308BT5FSHYPB_SFII

>> Input/Output buffer used for GPIO
