TPS65987D: Can I use NO external SPI Flash?

Part Number: TPS65987D

Dear,

I'm designing a USB powered device using the TPS65987D, which will sink 15V 3A. 

Can I use NO external SPI Flash? Is the default configuration[3] sufficient?

I'll also have no onboard MCU for I2C. The I2C will be used only for initial setup with the Aardvark adapter.

    Hi Jeong,

    The TPS65987D does not always require a flash. There are some default configurations highlighted in section 8.4.1 of the device datasheet. However, functionality is limited in these operation modes and it is suggested to use a Flash or have an external EC boot the device so that the latest patch can be used.
