1.1 MSP-FET-432ADPTR
1.1.1 Introduction
The MSP-FET-432ADPTR is an adapter to convert the 14-pin JTAG connector to either standard ARM 10-
pin or ARM 20-pin connectors. This allows for use of the MSP-FET debug probe with MSP432 Cortex-M
devices.
1.1.2 Key Features
• Use MSP-FET to debug MSP432 Cortex-M Devices
• 10-pin ARM support
• 20-pin ARM support
1.1.3 Kit Contents
• 1x MSP-FET-432ADPTR 14-pin JTAG to ARM adapter
1.1.4 Configuration and Usage
The MSP-FET-432ADPTR allows the use of the MSP-FET debug probe with the MSP432 Cortex-M family
of devices. Operation is straight-forward, with only one selection for how the power is sourced. This
selection is required because of the difference in the power source and sense behavior of the MSP-FET
and the ARM debug standard.
The MSP-FET debug probe has two power states:
1. VCC Output
• MSP-FET outputs a voltage to the target.
• Output voltage is configurable in the IDE.
• In VCC output state, the MSP-FET voltage sense functionality is not enabled.
2. VCC Sense
• MSP-FET senses an existing external voltage (not from the MSP-FET itself).
• The JTAG signals are level shifted accordingly to match this voltage.
• In VCC Sense state, the MSP-FET output voltage is not provided.
The Cortex-M debug standard works a bit differently. In this standard, the VCC Sense is always active, no
matter where the external voltage is coming from. Some debug probes, such as the IAR I-jet and Segger
J-Link have a voltage output, all while still sensing the VCC Sense.
Table 1-1. Matrix of S1 Switch Orientation Compared to ARM Connector Option
VCC Sense (S1 Left) VCC Output (S1 Right)
ARM 20-pin connector • External power is sensed through ARM pin 1
• External power needs to be connected to
debug target
• Power is provided by the MSP-FET through
ARM pin 19.
• Alternatively, power can be wired to the target
using connector J4.
• This output matches other ARM debug probes
like IAR i-Jet and SEGGER J-Link
• Note that the IAR i-Jet outputs 3.3 V, and
SEGGER J-Link outputs 5 V on this pin.
Ensure the target accounts for the specific
voltage output by MSP-FET.
ARM 10-pin connector • External power is sensed through ARM pin 1
• External power needs to be connected to
debug target
• There is no pin to connect the power output
on the 10 pin connector
• Power output is provided on connector J4.
This can be wired to the target board.

1.2 MSP-TS432PZ100
1.2.1 Introduction
NOTE: This kit does not include MSP432 microcontroller samples. To sample the compatible
devices, visit the product page or select the related MCU after adding the tool to the TI Store
cart: MSP432P401R.
The MSP-TS432PZ100 is a stand-alone ZIF socket target board used to program and debug the MSP432
MCU in-system through the JTAG interface or the Serial Wire Debug (SWD 2-wire JTAG) protocol. Two
standard ARM Cortex-M debug connectors provide connectivity to a large number of debug probes from
Texas Instruments and third parties.
All device pins are readily accessible through dedicated headers, which makes the board the ideal center
of a prototype setup.
1.2.2 Key Features
• ZIF socket for 100-pin QFP (PZ) packages
• Access to all 100 device pins
• LEDs and buttons
• 2 x Cortex-M JTAG connectors supporting all 10- or 20-pin compatible debug probes
1.2.3 Kit Contents
• One READ ME FIRST document
• One MSP-TS432PZ100 target socket board
• One TI Terms and Conditions for Evaluation Modules
• One 32.768-kHz crystal from Micro Crystal
• Four SAM1029-25-ND 25-pin 100-mil through-hole male headers
• Four SAM1213-25-ND 25-pin 100-mil through-hole female headers
1.2.4 Configuration and Usage
Table 1-3 lists the devices that are compatible with the MSP-TS432PZ100 target socket board.

1.2.4.1 Board Configuration For External Target Power Supply
If the application needs to operate in stand-alone mode (for example, to measure current consumption
without debug overhead) or when using ARM Cortex-M debug probes that do not provide power for the
target device (for example, TI XDS100, XDS200, Keil ULINK2, or Keil ULINK Pro), power must be
supplied externally to the target socket board.
Always follow the voltage limits defined in the device data sheet. Also make sure that the following
jumpers have been set as shown here before connecting the debug probe and power supply (see
Figure 1-2):
• JP8: Open
• JP12: Open
• J1: Close 2-3
• JP1: Closed
• JP2: Closed
• J16: Closed
• J2: Connect external VCC to pin 1, and external GND to pins 2 or 3

1.2.4.2 Board Configuration When Using ARM®Cortex®-M Debug Probes With Target Power Supply
Capability
Some third-party ARM Cortex-M debuggers (for example, Segger J-Link and IAR i-Jet) can optionally
supply a 5-V voltage to the target system through pin 19 of the debug connector. The LDO IC2 uses this
voltage to generate the 3.3-V target supply voltage. To use the LDO, make sure the following jumpers are
set as shown here before connecting the debug probe (see Figure 1-3):
• JP8: Closed
• JP12: Closed
• J1: Close 1-2
• JP1: Closed
• JP2: Closed
• JP16: Closed
If the debug probe supplies a logic level voltage through pin 19, the LDO can be entirely bypassed using
JP15. Always follow the voltage limits defined in the device data sheet.
