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.
XDS110 EnergyTrace™ Technology
The LP-EM-CC2340R5 is compatible with EnergyTrace technology.
EnergyTrace implements a new method for measuring MCU current consumption. It uses
GND 20
a DC-DC solution to measure the time density of charge pulses, allowing accuracy on
19
ultra low power measurements. Its high dynamic range (700 nA to 400 mA) and fast
DIO11 SPI_CS 18
sampling rate (256 kSPS) captures the complete operational profile of the wireless MCU.
