TPS65987DDJ: How can I use IC without FLASH memory?

Aleksandr Dudko

Part Number: TPS65987DDJ

Hi everyone

I am creating new project with TPS65987DDJ. I finded table with Device Default Configurations. But I didn't find Default Configurations of GPIO pins. I need to use one GPIO pin like control signal of MUX SuperSpeed lines. And one more like Enable signal of external DC/DCs when power source is greate than 5V@900mA. My device is UFP (sink). I want to use Configuration 3 (Table 7. Device Default Configurations P.41 of DataSheet) and BP_NoWait config.
What GPIO can I use like "Port 0 Cable Orientation Event" by default (without external flash memory)?

What GPIO can I use like "Ice Lake High Current Contract Active Event" by default (without external flash memory)?

Thanks

Hello,

If you want to use GPIO's from the TPS65987DDJ, then you must use an external flash device, and create a project file using the application configuration tool

But TPS65987DDJ have Default Configurations. You can read it on page 41 of DataSheet. I want to use this config.

Hello,

Yes I understand the request and what default configurations you are referring to. However, if you would like to use GPIO's in your design, you must use the application configuration tool and load a patch bundle generated by the configuration tool onto an external flash.

I understood... I thought this IC have standard default (without external memory) configuration for standard use (UFP) with flip signal USB Type-C for external MUX.
I will use external memory.
Thank you for your fast answers.
Unfortunately, tool for configuration this IC doesn't work on my PC.
