RESETO#
2ms after VCC>3.5v and the internal clock starts up, then clamps its output to the 3.3v
output of the internal regulator. Taking RESET# low will also force RESETO# to
go high impedance. RESET0# is NOT affected by a USB Bus Reset.
GROUND
3V3OUT
internal 3.3v supply to the USB transceiver cell and the RSTOUT# pin. A small amount of current
(<=5mA) can be drawn from this pin to power external 3.3v logic if required.
Ground
SWVCC
and Q1 MOSFET power switch. R5 and C3 control the power-up rate to help limit inrush current.
(I/O) Port Pin A0 connected to the SX28 microcontroller
(I/O) Port Pin C2 connected to the SX28 microcontroller.
(I/O) Port Pin C3 connected to the SX28 microcontroller.
(In) Can be used by an external device to reset the SX28. Can be left disconnected if not
(Out) Power from EXTVCC (Pin 19) controlled via Pin 10 (POWERN#) of the FT245BM
(In) Can be used by an external device to reset the FT245BM. Can be left disconnected if
(Out) Output from the integrated L.D.O. regulator. Its primary purpose is to provide the
(Out) Output of the FT245BM’s internal Reset Generator. Stays high impedance for ~
