USB-232
HW143-19

Basic Operation
To the electronic system (‘device’), USB-232 looks like a
serial UART. To the PC (‘host’), it looks like a Human
Interface Device (HID) with which it may exchange
information using simple commands.
Using the HID USB profile means that no driver
installation is required and immediate compatibility is
assured on Windows, Linux and OS systems.
Additionally, software can find the device automatically
without needing to know which virtual COM port it is
occupying.
Pin Functions
The pin functions are shown in table 2. The function of
the virtual I/O pins is reconfigurable, so their default
settings are also shown. The output pins are in a tri-
state condition until ~20μs after power-on.

The pin functions are described in detail below.
Vss, Vdd, Vusb
Vss is the power supply ground reference. Vdd should
be connected to a regulated supply, for example the
USB bus power.
Vusb should be connected, via a
470nF capacitor, to Vss. See for example C8 in figure 2.
OSC1, OSC2
OSC1 and OSC2 should be connected to a 12MHz
parallel cut crystal circuit with 22pF capacitors. It may
be replaced with a 12MHz resonator with 0.25% total
tolerance.
RxD, TxD
Active low serial data input and output.
Vpp, PGC, PCD
TEAclipper programming pins. Refer to the Delivery
and Programming section for details. Note that the Vpp
pin may be subject to voltages as high as 12V during
programming.
VIO pins
The VIO pin functions can be reconfigured as detailed in
the customization section. The default functions are
shown in table 2. The pins can be configured as follows.
No Function
The pin is a digital input that has no effect. To minimize
power consumption, it should be biased high or low.
This setting is available on all VIOs.
Reset
The pin is an active low reset input.
Resetting the
device effectively implements the soft detach function.
This setting is available on VIO0 only.
USB Power Sense
If the device is capable of operating while not plugged
into a USB port, a USB Power Sense input should be
provided.
This pin should indicate that a voltage is
detected on the V+ pin of the USB connector. It is used
to reduce power consumption by entering into a sleep
mode when the USB is not present, and also to ensure
that the USB engine correctly initializes when the device
is plugged in. The UART is not operational during sleep.
This setting must be on VIO9 or VIO10.
Self Power Sense
If the device is capable of operating while not plugged
into a USB port, a Self Power Sense input may be
provided. This pin should indicate when the device is
not drawing power from the USB bus and can help the
PC manage its power budget. This setting is available
on any VIO pin.
Tx Indication
Output for connecting to a transmit indication LED. It
turns on for approximately 100ms when data has been
transmitted to the host. This setting is available on any
VIO pin except VIO0.
Rx Indication
Output for connecting to a receive indication LED. It
turns on for approximately 100ms when data has been
received from the host. This setting is available on any
VIO pin except VIO0.
