1. Yes, it means that CYPD3123-40LQXIT part includes the charge-through dongle application firmware and is pre-programmed with a USB bootloader.
2. We dont have any measured value for the time taken for firmware update as it depends on many factors based on the bootloader and host application implementation.
But I saw that the firmware update with I2C bootloader takes around 25s when using the EZ-PD Configuration Utility and USB-Serial device as a bridge. I think the firmware update with USB bootloader will take lesser time since there is no bridge controller involved and the I2C interface is slower when compared to updating directly through the USB interface.
Thank you so much for your kinds comment.
