Board Overview
1 Board Overview
The SimpleLink™ Ethernet MSP432E411Y microcontroller EVM is an evaluation platform for SimpleLink
Arm®Cortex®-M4F-based Ethernet microcontrollers. The MSP432E411Y-BGAEVM demonstrates the
MSP432E411Y microcontroller with its on-chip 10/100 Ethernet MAC and PHY, USB 2.0, LCD controller,
External Peripheral Interface (EPI), hibernation module, motion control pulse-width modulation, and a
multitude of simultaneous serial connectivity. The MSP432E411Y-BGAEVM also features a fully compliant
40-pin BoosterPack™ plug-in module header, a user switch, two user LEDs, and dedicated reset and
wake switches.
The preprogrammed quick start application on the EVM is an application that performs a self-test on the
onboard SDRAM by writing and reading back values in memory using the MSP432E411Y EPI. The selftest blinks an LED to indicate that the test passes. Figure 1 shows the MSP432E411Y-BGAEVM with key
features highlighted.

2 Power the MSP432E411Y-BGAEVM
The MSP432E411Y-BGAEVM requires a 3.3-V power supply, which can be provided in any of several
ways:
• Provide 3.3 V from an external emulator through the 20-pin Arm JTAG interface
• Provide 3.3 V directly to the 3.3V pin on the external power header (J11)
• Provide 5 V to the 5V pin on the external power header (J11) and using the onboard LDO to generate
3.3 V
• Provide 3.3 V and 5 V both to the external power header (J11)
2.1 Emulator Power
To use an external emulator as a power source, use an emulator that supplies 3.3 V to pin 1 on the Arm
20-pin JTAG interface. When 3.3 V is supplied to the board from the emulator, disconnect the output of
the onboard 3.3-V LDO (U5) from the 3.3-V power rail by removing the jumper on JP8. Figure 2 shows the
location of JP8.
Power the MSP432E411Y-BGAEVM
If USB host functionality is required from the onboard USB OTG connector, provide 5 V to the board
through the external power header (J11) or the BoosterPack header (J3).
2.2 External 3.3-V Source Only
To use an external 3.3-V source to power the EVM, connect the 3.3-V and GND lines of the supply to the
3.3V and GND pins of the external power header (J11). Disconnect the onboard 3.3-V LDO (U5) from the
3.3-V power rail by removing the jumper on JP8 to prevent back-powering the LDO. Figure 2 shows the
location of JP8. If USB host functionality is required from the onboard USB-OTG connector, also provide
5 V to the board. Use the external 3.3-V and 5-V power option in Section 2.4.
2.3 External 5-V Source Only
To use an external 5-V source to power the EVM, connect the 5-V and GND lines of the supply to the 5V
and GND pins of the external power header (J11) or to the 5V pin on the BoosterPack header (J3).
Connect the onboard 3.3-V LDO (U5) to the 3.3-V power rail by populating the jumper on JP8 to connect
the output of the LDO to the 3.3-V power rail. Figure 2 shows the location for JP8.

2.4 External 3.3-V and 5-V Source
To use external 3.3-V and 5-V supplies to power the EVM, connect the 3.3-V, 5-V, and GND pins of the
supply to the 3.3V, 5V, and GND pins of the external power header (J11) or the BoosterPack headers (J1
for 3.3V and J3 for 5V). Disconnect the onboard 3.3-V LDO (U5) from the 3.3-V power rail by removing
the jumper on JP8 to prevent back-powering the LDO. Figure 2 shows the location for JP8.
2.5 Measure Current Consumption
To measure current consumption, remove the JP1, JP2, or JP3 jumpers and place an ammeter across the
header pins. Connect this jumper when not performing current measurements. Figure 3 shows the location
of JP1, JP2, and JP3. Table 1 lists which power rail to measure on each jumper.

Header Pinouts and Connections
3.3 J7 – External Peripheral Interface Header
Header J7 contains all the signals for the MSP432E411Y’s External Peripheral Interface (EPI). The EPI
can be connected to an onboard IS42S16320F-7TL – 512 megabit SDRAM, U2, buy shorting all the
header pins on J7 horizontally, as shown in Figure 5. Alternatively, the EPI pins can be used to connect to
an external device by removing the headers on J7, and connecting to the outside pins of J7, as shown in
Figure 6.
