Discussion - Hardware / FT230XQ: Powering VCC with 3.3V
« on: February 04, 2020, 10:36:34 AM »
Hi,
I am integrating the FT230XQ chip into my design, and am powering VCC with 3.3V (regulated from USB_VBUS). Consequently, I followed the datasheet which states "3V3OUT on pin 8 is an input pin and should be connected to pin10". Please could you advise whether the attached schematic is correct? I should highlight that the 3.3V rail supplying VCC, VCCIO, and 3V3OUT is derived from USB_VBUS using an LDO regulator.
Thanks.
