Delivery and Programming
In high volumes (5K+), expandIO-USB is available
reeled with your custom settings preloaded.
devices listed in table 9 are commonly stocked by
distributors.
USB-expandIO-SS may be supplied with an ID label, or
it may be identified with a red mark on the package.
Programming expandIO-USB
expandIO-USB may be programmed in-circuit provided
the programming signals PGC, PGD and Vpp are
protected against contention. In particular, note that the
Vpp line is subject to a voltage of up to 13V during
programming. Nothing else should be connected to this
input except via a 22k pull-up resistor.
Since the programming time is fast, no programming
socket is required for the TEAclipper. It may be leaned
against five plate-through holes as described in figure
10. In-circuit programming connections of some form
should always be provided, even if the device is
supplied pre-loaded, in order to facilitate firmware
upgrades.
Evaluation Board
expandIO-USB may be evaluated with the Firmware
Factory USB Products Eval Board (figure 11).
components which must be fitted are shown in table 10.

In addition, the prototyping area on the left may be used
to add components to which the expandIO-USB will
interface.
The printed circuit board integrates an edge connector
of USB Type A format. This may be plugged into a USB
extension cable.
The HIDconfig.exe application can be used to discover
and test the evaluation circuit prior to writing a software
application to do the task.
