PCB

Type

Description

1

5V0

5V0

PWR

Input

5.0 V module supply pin. This pin provides the 5.0V output on the

USB ‘A’ type socket, and also the 3.3V supply to VNCL2, via an on-

board 3.3 V L.D.O.

2

LED1

LD1

Output

USB port 1 traffic activity indicator LED. This pin is hard wired to a

green LED on board the PCB. It is also brought out onto this pin

which allows for the possibility of bring- ing out an additional LED

traffic indicator out of the VDIP1 board. For example, if the VDIP1

USB connector is brought out onto an instrument front panel, an

activity LED could be mounted along side it.

3

LED2

LD2

Output

USB port 2 traffic activity indicator LED. This pin is hard wired to a

green LED on board the PCB. It is also brought out onto this pin

which allows for the possibility of bring- ing out an additional LED

traffic indicator out of the VDIP1 board. For example, if the VDIP1

USB connector is brought out onto an instrument front panel, an

activity LED could be mounted along side it.

USBD1P

U1P

I/O

USB host / slave port 1 - USB Data Signal Plus with integrated pull

up / pull down resistor. Module has on board 27 Ω USB series

resistor. This pin can be brought out along with pin 5 to provide a

second USB port, if required

5

USBD1M

U1M

I/O

USB host / slave port 1 - USB Data Signal Minus with integrated pull

up / pull down resistor. Module has on board 27 Ω USB series

resistor. This pin can be brought out along with pin 4 to provide a

second USB port, if required

Input

Can be used by an external device to reset the VNC1L. This pin can be used

in combination with PROG# and the UART / parallel FIFO / SPI interface to

program firmware into the Vinculum

23

PROG#

PG#

Input

This pin is used in combination with the RESET# pin and the UART / parallel

FIFO / SPI interface to pro gra m fir mware into t he VNC1L.
