Introducing the CodeWarrior™ USB TAP Emulator

Operating Requirements

Operating Requirements
Before setting up your system, you should make sure that the operating environment is
prepared.

Standard Electrostatic Precautions

This instrument contains static-sensitive components that are subject to damage from
electrostatic discharge. Use standard ESD precautions when transporting, handling, or
using the instrument and the target, when connecting/disconnecting the instrument and
the target, and when removing the cover of the instrument.
We recommend that you use the following precautions:
• Use wrist straps or heel bands with a 1 MΩ resistor connected to ground.
• On the work surface and floor, use static conductive mats with a 1 MΩ resistor
connected to ground.
• Keep high static-producing items, such as non-ESD-approved plastics, tape and
packaging foam, away from the instrument and the target.
The above precautions should be considered as minimum requirements for a static-
controlled environment.

Electrical Requirements

The USB TAP emulator is powered through the USB cable and does not use an
external power supply. The USB TAP emulator is designed to be plugged directly into
a host computer, but also can work with self-powered hubs. Bus powered hubs may be
unable to provide sufficient power for the USB TAP, which requires 200 mA. If
insufficient power is available, your host operating system will indicate this failure
and the USB TAP emulator will go into a low power suspend mode. If your hub is not
able to provide sufficient power, connect the USB TAP directly to your host PC, or
purchase a self-powered USB hub.

Operating Temperature

The USB TAP emulator can operate in a temperature range of 0 to 40 °C (32 to 104
°F).
