EnergyTrace Profile
EnergyTrace Profile runtime and energy data for low power modes along with each
function run during Active Mode.
Graphical Power Data in Code Composer Studio
These two tabs of the EnergyTrace Technology window show a graph over time of
power and energy.
Available in the LP-XDS110ET debug probe and selected LaunchPads
UART (DIO20, DIO22), Reset (LP_RST) and JTAG (SWCK and SWD) are also present in the
LP-EM Debug Connector. Power (GND, 3V3 and 5V) is also provided.
*This function is not connected to the LaunchPad connector by default.
SWRU588
EnergyTrace implements a new method for measuring MCU current consumption. It uses
a DC-DC solution to measure the time density of charge pulses, allowing accuracy on
ultra low power measurements. Its high dynamic range (700 nA to 400 mA) and fast
sampling rate (256 kSPS) captures the complete operational profile of the wireless MCU.

Hardware setup
What do you need?
To use your new LaunchPad, you need to connect an external debug probe to either the 20-pin
LP-EM debug connector on the edge of the board or to the 10-pin debug connector and supply
power separately.
LP-XDS110 or LP-XDS110ET

Option 1: Using the LP-EM debug connector
This is the easiest way to setup the hardware. It requires either an LP-XDS110 or
LP-XDS110ET debug probe (sold separately).
Simply connect the connector at the edge of the debug probe to its counterpart on the
LaunchPad and connect the USB port of the debug probe to the host computer. A secondary
UART communications channel will also be available and power to the LaunchPad will be
provided directly.
LP-EM debug connector
Together with a LP-XDS110 or
LP-XDS110ET, allows:
- Debugging and programming
- Communicating to the host via UART
- Powering the microcontroller

When using the 10-pin debug connector, the UART communications channel must be wired
separately (this connector does not carry UART signals).

Option 2: Using the 10-pin debug connector
Either a standalone debug probe or a separate LaunchPad with a built-in debug probe can
be used.
Connect the two boards as shown in the picture below:
This LaunchPad is great for...
- Battery-operated wireless applications operating in the 2.4GHz ISM RF band
- Add RF capabilities to your product using one of the supported protocols: Bluetooth®5.3 Low Energy,
Zigbee®, SimpleLinkTM 15.4 stack and proprietary protocols
If using a standalone debug probe, consult its documentation to see if it supports the ARM
Cortex-M 10-pin standard.
