TPS65987D: TPS65987D firmware

Part Number: TPS65987D

Dear team,

I have a question about TPS65987D, the firmware will write into the SPI flash or write into the main CPU?

Thanks.

Best regards,

Sammi

    Hello Sammi,

    On power up (either through VBUS or VIN_3V3), the TPS65987D will read the contents of the external SPI flash, and load .bin file into its internal RAM. You only need to program the SPI flash once, and the TPS65987D will need to read its contents during each power cycle as the TPS65987D clears its RAM after each power cycle. 

    Hope this helps answer your question
