Customization
The product can be customized in one of three ways:
Delivery and Programming
USB-232 is available pre-programmed in 28-pin DIL and
20-pin SSOP packages. USB-232-SS (SSOP package)
may be supplied with an ID label, or it may be identified
with a yellow mark on the package.
In high volumes (5K+), USB-232 is available reeled with
your custom settings preloaded, in any available
package.
TEAclipper Programming
If practical, a TEAclipper programming socket should be
added to the circuit board in order to facilitate in-circuit
firmware updates.
During programming, these connections must be
protected against contention.
Vpp is subject to 13V during programming. Nothing else
should be connected to Vpp except via a 22k pull-up
resistor.
The TEAclipper connector format is shown in figure 13.
Since the programming time is fast, no programming

against the plate-through holes shown.
It is strongly recommended that this connector is
included in circuits even if in-circuit programming is not
anticipated, since this allows you to upgrade the
firmware if necessary.
Evaluation Board
USB-232 may be evaluated with the Firmware Factory
USB Products Eval Board (figure 14). The components
which must be fitted are shown in table 5. In addition,
the following wire links must be made:
- TxD28 to TxD near the MAX222.
- RxD28 to RxD near the MAX222.
- Pin VIO9/CTS (DIL pin 22) to CTS near the MAX222.
- Pin VIO6/RTS (DIL pin 11) to RTS near the MAX222.
- Pin VIO5/Suspend# (DIL pin 24) to SHDN near the
- Pin VIO10/Send (DIL pin 21) to Vin
The prototyping area on the left of the board may be
used to add components to which the expandIO-USB
will interface. In figure 11, an active low LED has been
connected to the AllSysGo# pin and active high LEDs to
the Tx and Rx indicators.
The printed circuit board integrates an edge connector
of USB Type A format. This may be plugged into a USB
extension cable.
