UM10973 NXP Semiconductors LPCXpresso54114 1. Introduction The LPCXpresso™ family of boards provides a powerful and flexible development system for NXP's Cortex®-M family of MCUs. They can be used with a wide range of development tools, including the NXP’s LPCXpresso IDE. The LPCXpresso54114 board has been developed by NXP to enable evaluation of and prototyping with the LPC54110 family of MCUs, and is based on the LPC54114J256BD64 version of the MCU. Fig 1.

UM10973 NXP Semiconductors LPCXpresso54114 Circuit ref Description Ref section J5 Target MCU Power / USB Device connector. Connect this micro USB B-type n/a connector to a +5V power source when it is desired to power only the Target MCU, and leave the on-board Link2 debug probe unpowered. J6 Link2 micro USB B-type connector. Powers both the Link2 side of the board and LPC54114 Target side of the board.
UM10973 NXP Semiconductors LPCXpresso54114 Circuit ref Description P1 10-pin SWD connector – The SWD connector is used to debug the LPC54114 Target from an external debug probe. The same SWD connector can also be used to connect the on-board Link2 debug probe to an off-board target MCU (for this JP1 must be shunted). LPC54114 VDD current monitor Vsense measurement. The Vsense can be measured with a volt meter. Pin 1 (square pad) is positive and pin 2 is negative.
UM10973 NXP Semiconductors LPCXpresso54114 3. Getting Started By default, the LPCXpresso54114 is configured to use the on-board debug probe (Link2) to debug the on-board target (LPC54114), using the CMSIS-DAP debug protocol preprogrammed into the Link2 Flash memory. The LPCXpresso IDE (available for free download at http://www.nxp.com/lpcxpressoide) or development tools that support the CMSIS-DAP protocol can be used in the default configuration.

UM10973 NXP Semiconductors LPCXpresso54114 The LPC54114 Target VDD selection of 1.8V or 3.3V is made at JP9, with 3.3V set as the default. Fig 4. Board power diagram 5.1 LPCXpresso54114 current measurement The LPC54114 current can be measured by measuring the voltage across a sense resistor in series with the supply, a current meter or using the on board current measurement circuit. Each of these methods will be described in subsections below.
UM10973 NXP Semiconductors LPCXpresso54114 5.1.1 LPC54114 Vsense resistor current measurement The voltage across a series 4.12Ω resistor with the target LPC54114 VDD can be manually measured at P2 on the PCB. The voltmeter positive probe is applied to P2 pin 1 (square pad) and negative probe to P2 pin 2. Use Ohm’s law to calculate the current (LPC54114 current = measured voltage / 4.12Ω). As an example if the measured voltage is 10mV, then 10e-3 / 4.12Ω = 2.44mA.

Current measurement circuit error 5.1.4 Shield board current measurement To use the on-board current measurement circuitry, any expansion board must match the functionality of the LPCXpresso54114. Refer to the board schematics for more information. 6. Debug Configurations The LPCXpresso54114 LQFP board has a built-in debug probe referred to as “Link2”.
UM10973 NXP Semiconductors LPCXpresso54114 6.1.1 Debugging LPC54114 target using on-board (Link2) debug probe To use the on-board Link debug probe, the LPCXpresso54114 board must be powered from the Link2 USB connector J7, and jumper JP2 must be fitted in position pin 1 - 2 (Local Target). Jumper JP1 must be open to enable the target LPC54114. Connecting the micro USB J7 to a host computer will power the Link and Target sections of the board and provide the USB link to the debug tool software. 6.1.
