WARNING: When the controlCARD is used in a high-voltage setup, it is the user’s responsibility to confirm that the voltages and isolation requirements are identified and understood prior to energizing the board or simulation. When energized, the controlCARD or components connected to the controlCARD should not be touched. Furthermore, the capacitor C7:A should be removed to minimize the possibility of leakage current flowing across the isolation barrier of the controlCARD.
Table 6-1 Hardware Connections
Connectors
J1:AEmulation/UART connector/Power - USB-C connector used to provide XDS110 emulation and USB-to-UART (SCI) communication through MSP432 logic. S1:A determines which connections are enabled to the MCU.

The USB-C connector also provides power on the controlCARD.

J1FSI Header – This header is keyed, contains 2 data lines, and has 3.3-V power.
LEDs
LED1:ATurns on (red) when 5 V is supplied to the controlCARD
(5 V can be supplied either through the USB-C connector or externally through the HSEC connector)
LED2:A/LED3:AJTAG/UART RX/TX toggle indicator (blue)
D1Controlled by GPIO-31 with negative logic (red)
D2Controlled by GPIO-34 with negative logic (red)
D3Turns on (green) when 3.3 V is supplied to the controlCARD
Resistors and Capacitors
R25-R47ADC RC input filter resistors: Series resistors which can be used to create an RC filter on the ADC's input.
C29-C51ADC RC input filter capacitors: Optional capacitors, not populated by default, for the ADC input's RC filters.
Switches
S1:AIsolated emulation and UART communication enable switches:
S1:A Position 1 – USB JTAG Enable:
  • ON – All 4 JTAG signals between the XDS110 emulation logic and the MCU will be connected. This setting is valid when the MCU is being debugged or programmed via the on-card XDS110 emulator.
  • OFF – The XDS110 emulation logic will NOT be connected to the MCU JTAG pins. This setting is valid when the device will boot from FLASH, boot from a peripheral directly, or when an external JTAG emulator will be used.
S1:A Position 2 – USB UART communication enable:
  • ON – The C2000 MCU’s GPIO-28 and GPIO-29 will be connected to the MSP432 on the XDS110. This allows UART communication to a computer COM port. However, in this position, GPIO-28 and GPIO-29 will be reserved for COM port use. The corresponding pins on the 180-pin controlCARD connector cannot be used for another function.
  • OFF – The C2000 MCU's GPIO-28 and GPIO-29 will NOT be connected to the MSP432 on the XDS110. The

    Corresponding pins on the 180-pin controlCARD connector can be used for another function.

S1SPIA or external crystal selection switch: This switch enables the use of SPIA or an external crystal. This methodology was required to support the full range of TI's baseboards and is not recommended in a production system. For full details, see Section 5.2.
S2Boot Mode Switch: Controls the Boot Options of the F280039C device, see Table 6-2. For a full description, see the device-specific data sheet.
S3VREFHI Source Configuration Switch: This switch selects the source for VREFHI (internal or external through the 180-pin controlCARD connector)
  • Upward position – Internal voltage reference
  • Downward Position – External voltage reference

Note that additional software configuration is required to enable the ADC's internal or external voltage reference.
Test Points
TP1:A USB 5.0-V input: This is the 5-V supply from the USB-C connector.
TP2:A USB GND input: This GND from the USB-C connector.
TP1 HSEC 5.0-V input: 5.0-V input provided to the controlCARD.
TP2 Unfiltered 3.3 V: Provides power to the F280039C device.
TP3 MCU 1.2 V: VDD "core supply" to the F280039C device. Note that this controlCARD has been designed to use the internal voltage regulator.
TP4 Device Ground
TP5 XRSn of F280039C device: Connected to the undervoltage output from the 3.3-V voltage supervisor.
TP6 Overvoltage output: Connected to the overvoltage output from the 3.3-V voltage supervisor.
Note: On the front of the controlCARD, test points are indicated by their TPx number.
On the back of the controlCARD, test points are indicated by their signal.
