Table 1 - DLP-USB245M PINOUT DESCRIPTION

Pin# Description

1 BOARD ID (Out) Identies the board as either a DLP-USB245M or DLP-USB232M. High for DLP-

USB232M and low for DLP-USB245M.

2 Ground

3 RESET# (In) Can be used by an external device to reset the FT245BM. If not required this pin must

be tied to VCC.

4 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.

5 Ground

6 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.

7 Ground

8 SLEEP (Out) Goes Low after the device is congured via USB, then high during USB suspend.

Can be used to control power to external logic using a P-Channel Logic Level

MOSFET switch.
