I bought some FT230X (FT230XS) USB-USART bridge chip recently for a new design.  FT230X is not only cheaper than the traditional FT232RL, but also offers a new fancy “USB charger detection” function. This interests me because I’m quickly running out of desk space and power socket. I wish the new device to be solely powered by USB and/or battery.

    Did they finally fix the flaw in these chips? I went back to the FT232RL a couple of years ago after a bad experience with these ones locking up.
