Introduction www.ti.com
1.1 Introduction
The MSP-GANG430 is an MSP430 device programmer that can program up to eight identical MSP430
flash devices at the same time. The MSP-GANG430 connects to the host PC using a standard RS232
serial connection. The MSP-GANG430 provides flexible device programming options as described in
Chapter 2.
The MSP-GANG430 is not a gang programmer in the traditional sense; i.e., there are not eight sockets
provided to program the target devices. Instead, the MSP-GANG430 is designed to connect to the target
devices in-circuit (i.e., the target devices are mounted in the final circuit/system). The MSP-GANG430
accesses the target devices using connectors to the JTAG signals.
Chapter 6 contains a schematic that shows how the signals from the MSP-GANG430 can be brought out
to each of the target devices via an MSP430-standard JTAG connector. The circuit could easily be
modified to connect the signals to the target device pins directly (via a socket) if a traditional gang
programmer is desired.
The MSP-GANG430 is provided with an expansion board that implements the interconnections between
the MSP-GANG430 and multiple target devices. Eight cables are provided that connect the expansion
board to eight target devices (via a JTAG connector).
1.2 Software Installation
Always use the latest software version, which can be downloaded from the MSP430 web site at
www.msp430.com.
To install the MSP-GANG430 software:
1. Insert the MSP430 CD-ROM into the CD-ROM drive of the computer. Setup automatically opens the
default browser of the computer and displays the MSP430 start page.
If the start page does not open automatically, open the file index.htm located in the root directory of the
CD-ROM using a web browser. The MSP430 start page is displayed in the browser window.
2. Select Tools & Software.
3. Select MSP-GANG430 Gang Programmer.
4. Select Save this program to disk under the File Download options and click OK. A Save As dialog is
displayed.
5. Using the Save As dialog, save the GANG430_Rxxx.exe program to the computer. Make a note of the
directory path to this file.
6. Navigate to this file (GANG430_Rxxx.exe) and run it. A welcome message is displayed on the screen.
7. The setup program guides you through the installation process. Follow the setup instructions on the
screen.
8. On completion of the setup program execution, the MSP-GANG430 program icons are created in the
selected folder. Click on the GANG430 Read Me First icon to obtain important information about the
MSP-GANG430 hardware and software.
9. The appropriate program group and icons are added to the Windows desktop.
10. To start the MSP-GANG430 software, click the GANG430 icon in the selected program group (the
default program group is ADT430).

1.3 Hardware Installation
To install the MSP-GANG430 hardware:
1. Connect the MSP-GANG430 to the serial port (COM1 to COM15 or extension board) of the PC using
the 9-pin Sub-D connector.
2. Connect an external power supply to the MSP-GANG430. The voltage of the power supply must be
between 9 V and 15 V dc and must be capable of providing a minimum current of 300 mA. The center
post of the power supply connector on the MSP-GANG430 is the positive-voltage terminal.
The power supply connection status is indicated by the yellow system LED on the MSP-GANG430.
3. Attach the expansion board to the 25-pin Sub-D connector on the MSP-GANG430. The expansion
board provides connectivity for up to eight targets, using the included 14-pin cables. The target
MSP430 flash devices can be in stand-alone sockets or can be on an application’s PCB, and they are
accessed via the JTAG signals.
NOTE: Maximum Signal Path Length: 60 cm
The maximum length of the signal path between the 25-pin Sub-D connector on the
MSP-GANG430 and a target device is 60 cm. If cables between the programmer and targets
are longer than 20 cm, serial resistors of 100 Ωshould be inserted on signals TCK and TMS
on the expansion board. TCK is on pin 4 and TMS is on pin 3 of the 25-pin Sub-D connector.
4. The MSP-GANG430 provides the selected power-supply voltage VCC (VCC_MSP on pins 7 and 14 of
the 25-pin Sub-D target connector; pin 2 on the 14-pin cable) to the target devices in application PCBs.
A maximum total current of 150 mA can be provided by the programmer to the targets.
When an external supply voltage VCC is used for the target systems, it also should be connected to the
sense input pin (MSP_VCC_IN on pin 15 of the 25-pin Sub-D target connector; pin 4 on the 14-pin
cable) of the programmer. This connection allows the integrated level shifters to match the target JTAG
signal levels with the external supply voltage.
If the expander PCB (25-pin Sub-D to 8 x 14-pin header) is used, the external supply voltage must be
connected to pin 4 of the 14-pin header at position 1.
CAUTION
When an external supply voltage is used for the target systems, it is important
to disconnect VCC_MSP from the targets to avoid power-supply conflicts that
could potential damage the MSP-GANG430 and the targets. Connect the
external supply voltage to MSP_VCC_IN.
It is not possible to simultaneously use the MSP-GANG430 with targets
powered by the MSP-GANG430 and with targets powered by an external
supply.

2.1.5 Description of the Gang430.ini File
The Gang430.ini file contains the MSP-GANG430 default settings and the most recently used GUI
settings.
2.1.5.1 Section [System]
The most recently used settings of the MSP-GANG430 GUI are stored in the Gang430.ini file when the
GUI application exits. This information is stored under the [System] section of the file. There are few
entries in this section that cannot be changed via the GUI.
JtagSpeed = 0 (default value is 0)
Set JtagSpeed = 1 to make the JTAG connection slower. This can be used for quality testing of the cable
between target devices and the MSP-GANG430.
VerifyMarginal = 0 (default value is 0)
Set VerifyMarginal = 0 to avoid the marginal check on devices with the marginal read feature. It can be
used to reduce the verification time. For more information, see the MSP430x2xx Family User's Guide or
MSP430x4xx Family User's Guide.
2.1.5.2 Section [User]
The initial settings for the following parameters are in the [User] section and may be modified by the user.
CaptionIndexed = 0 (default). The caption of the MSP-GANG430 GUI in the default state is MSP430
FLASH Gang Programmer.
CaptionIndexed = 1. The caption is extended with a suffix [n] to allow multiple-instance operation for
programming in automated production environment that uses caption titles for process control. The suffix n
represents the unique COMn port number for that instance. For example, for COM3, the caption is
displayed as MSP430 FLASH Gang Programmer [3].
2.1.5.3 Section [Timing]
The [Timing] section shows the approximate time, in milliseconds, that has elapsed for various operations
of the MSP-GANG430. The parameters under this section are updated after successful completion of the
associated operations. The information on the elapsed time is useful for development and setup. The
parameter that is most often useful is the time taken to complete a gang programming cycle, which is
reported in the TimeGangProg key in this section.
2.1.5.4 Section [Diagnostic]
The [Diagnostic] section is useful for automatic production using the MSP-GANG430. During gang
programming operation, Busy = 1. After completion of the operation, the information in the Result group
box in the GUI is also listed in this section for the following: Connected, EraseChecked, Verified,
SecureDevice, OverAll, and MiscErrors, if any. A Busy = 0 terminates that process and the diagnostics
can be read from the .ini file.
For example:
OverAll = 239 (0xEF) indicates that all channels except channel 5 were successfully processed
(channel 1 represents the LSB, channel 8 represents the MSB of a byte).
NOTE: When MiscErrors is nonzero, the diagnostic values are not valid for evaluation. Possible
values for MiscErrors are shown in Table 2-4.

16 ERROR: Could not set target voltage (VCCT) −MSP_VCC_IN pin connected?
2.1.6 Target Connector Functional Check
The MSP-GANG430 GUI diagnostics support a functional check of the target connector pins. The
functional check is invoked by selecting the Target Connector category in the Maintenance group box, and
clicking the Execute button with the appropriate Set Signals defined. The Set Signals value is the decimal
value that represents the combination of the appropriate control bits. The defined pin’s signal level is
available for measurement after execution of the functional check. The signal levels remain unchanged
until another configuration is set. The target connector functional check always must be terminated by
executing the End of Check setting (0x8000 = 32768) or by executing an hardware self test to initialize the
MSP-GANG430. Table 2-5 shows the details of the control bits.

Example 1
To check the logic-high level on TDO/TDI3 and VPP voltage level on TEST/VPP:
Enter 0x040A (0x0002 + 0x0008 + 0x0400) into Set Signal and click Execute.
The VCC at pin 10 and VPP at pin 17 can be measured now. All other pins remain at 0 V. The connector
case is electrically grounded, as are pins 19 to 23.
