(note that figure 5.2 is for illustration only and that the pins do not actually go all the way through the pcb) for a self - powered configuration it is necessary to prevent current from flowing back to the usb data lines when the connected usb host or hub has powered down. to carry out this function the umft230xa uses an on - board voltage divider network connected to the usb power bus and reset# pin. this operates on the principle that when no power is supplied to the vbus line , the ft230x will automatically be held in reset by a weak pull - down , when power is applied the v oltage divider will apply a weak 3.3v pull - up . driving a level to the reset# pin of the umft230xa will override the effect of th is voltage divider. when the ft230x is in reset the usb dp signal pull - up resistor connected to the data lines is disconnected and no current can flow down the usb lines. an example of interfacing the ft230x with a microcontrollers uart interface is also illustrated in figure 5 . 2 . this example shows the wire configuration of th e transfer and handshake lines. this example also illustrate s that a voltage other than 3.3v can be supplied to the ft230x s io port, this feature is described further and for bus powered mode in section 5.6 . a lternatively both the ft230x s io port and mcu can be powered from the 3v3out pin; this approach is described in section 5.5 . m c u v c c = 1 . 8 v C 3 . 3 v t x d r x d r t s # c t s # v c c = 5 v t x d r x d r t s # c t s # s o l d e r l i n k j p 2 - o p e n s o l d e r l i n k j p 1 - o p e n g n d s e l f p o w e r m o d e v a r i a b l e t t l m o d e v i o v c c i o 3 v 3 o u t v b u s v c c v i e w i n g p i n s t h o u r g h t h e b o a r d f r o m t h e t o p .

(note: it is impossible to be in suspended mode when enumerated.) (note that figure 5.3 is for illustration only and that the pins do not actually go all the way throug h the pcb) to implement a power switch using pwren#, configure a p - channel power mosfet to have a soft start by fitting a 10k pull - up, a 1k series resistor and a 100nf cap as shown in fi gure 5 . 3 . the ti me constant connecting the source of the p - channel mosfet to 3v3out instead of vbus can allow external logic to source 3.3v power from the ft230x without breaking usb compliancy. in this setup it is important that the vccio is not sourced from the drain of this mosfet, this is because the power used to drive the gate of this transistor is sourced from vccio. vccio should be connected directly to 3v3out for this setup to function effectively. it is also important that the external logic must and io core of the ft230x must not draw more that 50ma, this is because the current limit of the internal 3.3v regulator is 50ma. m c u t x d r x d r t s # c t s # t x d r x d r t s # c t s # s o l d e r l i n k j p 2 - c l o s e d s o l d e r l i n k j p 1 - c l o s e d g n d s d g 1 k 0 . 1 u f 0 . 1 u f s o f t s t a r t c i r c u i t p w r e n # c b u s x p - c h a n n e l p o w e r m o s f e t b u s p o w e r e d m o d e s e l f - s o r c e d 3 . 3 v t t l m o d e v c c 1 0 k v c c i o 3 v 3 o u t v b u s v c c 5 v v i e w i n g p i n s t h o u r g h t h e b o a r d f r o m t h e t o p .

(note that figure 5.4 is for illustration only and that the pins do not actually go all the way through the pcb) by default, a short is present between 3v3out (embedded voltage regulator) and vccio (io ports power input) by solder links jp1. if an external power supply is used to power the io ports this s older links needs to be open. this can be done by removing the solder linking the tw o pads of the solder links . the configuration described in this section can be implemented in either bus - powered mode or self - powered mode. note 1: the cbus and dbus pins are 5v tolerant; however these signals cannot drive signals at 5v ttl/cmos. vccio is not 5v tolerant; applying 5v to vccio will damage the chip. m c u v c c = 1 . 8 v C 3 . 3 v t x d r x d r t s # c t s # t x d r x d r t s # c t s # s o l d e r l i n k j p 2 - c l o s e d s o l d e r l i n k j p 1 - o p e n g n d v c c i o 3 v 3 o u t v b u s v c c v i e w i n g p i n s t h o u r g h t h e b o a r d f r o m t h e t o p .
