MSP Debuggers
Target V
CC
is selectable in a range between 1.8 V and 3.6 V in steps of 0.1 V.
Alternatively, the target can be supplied externally. In this case, the external voltage should be connected
to pin 4 of the 14-pin JTAG connector. MSP-FET tools adjusts the level of the JTAG signals to
automatically match the external V
CC
.
NOTE:
Only pin 2 (MSP-FET tool supplies target) or pin 4 (target is externally supplied) must be
connected. Both connections are not supported at the same time.
Even if an external supply powers the target device on the target socket module and any
user circuitry connected to the target socket module, the MSP-FET tool continues to be
powered from the PC through the USB interface.
NOTE:
MSP-FET430PIF only
The PC parallel ports with a connected MSP-FET430PIF can source a maximum current of
25 mA. Because of the ultra-low-power requirement of the MSP430, a stand-alone MSP430
does not exceed the provided current. However, if additional circuits are added, the current
limit could be exceeded. In this case, the MSP430 must be supplied externally.

Hardware Installation
This section describes how to install the drivers for all MSP debug probes. The drivers are needed to
enable the IDE (integrated development environment) to use the debug probe that is connected to the
system. There are four different ways to install the drivers.
1. CCS desktop: During the CCS setup, all MSP debug probe drivers are installed for all supported
operation systems.
2. CCS cloud: The automatic driver installer is included in the TI Cloud Agent application, which must be
downloaded when connecting a local MSP debug probe to CCS cloud.
3. Stand-alone driver installer: The stand-alone driver installer is available only for Windows. It installs all
MSP debug probe drivers.
4. Using another supported IDE such as IAR EW430 or the MSP-Flasher: During the setup, all MSP
debug probe drivers are installed.
4.1
MSP-FET430PIF
The MSP-FET430PIF has the following system requirements:
It supports only Windows XP with IAR EW430 version 5.xx.x and Code Composer Studio version 5.x.x. No
new development is scheduled to support MSP-FET430PIF.
Follow these steps to install the hardware for the MSP-FET430PIF tool:
1. Use the 25-pin ribbon cable to connect the debugger interface module to the parallel port of the PC.
The necessary driver for accessing the PC parallel port is installed automatically during CCS or IAR
Embedded Workbench installation. Note that a restart is required after the CCS or IAR Embedded
Workbench installation.
2. Use the 14-pin ribbon cable to connect the parallel-port debug interface to a target board which
contains the target MSP430 device.

MSP-FET430UIF, MSP-FET, eZ-FET, and eZ-FET Lite
NOTE:
The built-in DC-DC converter of the MSP-FET and eZ-FET emulators causes a load-
dependent amount of ripple on the output voltage (f
ripple
= 1 kHz to 50 kHz, V
rms_ripple
= 5 mV to
50 mV), which might affect sensitive analog and RF circuits that are supplied by the
emulator. For such sensitive circuits, TI recommends temporarily increasing the amount of
power supply decoupling used during development, using an emulator with an integrated
linear regulator (MSP-FET430UIF or eZ-FET430), or using a separate bench supply.
