Description
BOARD ID (Out) Identifies the board as either a DLP-USB245M or DLP-USB232M. High for DLP-
USB232M and low for DLP-USB245M.
Ground
RESET# (In) Can be used by an external device to reset the FT245BM. If not required this pin must
be tied to VCC.
RESETO# (Out) Output of the internal Reset Generator. Stays high impedance for ~ 2ms after
VCC > 3.5v and the internal clock starts up, then clamps it’s output to the 3.3v output of the internal
regulator. Taking RESET# low will also force RSTOUT# to go high impedance. RSTOUT# is NOT
affected by a USB Bus Reset.
Ground
3V3OUT (Out) Output from the integrated L.D.O. regulator. It’s primary purpose is to provide the
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
SLEEP (Out) Goes Low after the device is configured via USB, then high during USB suspend.
Can be used to control power to external logic using a P-Channel Logic Level
MOSFET switch.
