8.6.7 Supplying the board through ST-LINK/V2-1 USB

In this mode, the USB Host (a PC) is connected to the standard Micro-B USB receptacle of
the 32L496GDISCOVERY board by means of a USB cable. The connection event starts the
USB enumeration procedure.

In the initial phase of the enumeration procedure, the current supply capability of the USB
port of the host is limited to 100

mA. This value is high enough for normal operation since
only the ST-LINK/V2-1 part of 32L496GDISCOVERY draws power during that phase. If the
solder bridge SB11 is opened (default configuration), the ST890 U7 power switch is set to
the OFF position: this isolates the rest of 32L496GDISCOVERY from the power source.

In the next phase of the enumeration procedure, the host PC informs the ST-LINK/V2-1
facility of its capability to supply up to 500

mA. If this is accepted, the ST-LINK/V2-1 sets the
ST890 U7 switch to the ON position to supply power to the rest of the
32L496GDISCOVERY board. If the PC USB port is not capable of supplying up to 500
another power source should be used like the VIN pin of connector CN15.

Should a short-circuit occur on the board, the ST890 power switch protects the USB port of
the host against current demand exceeding 600

mA, In such an event, the FAULT LD4 red

LED lights on.

The 32L496GDISCOVERY board can also be supplied power by a USB power source that
is not supporting enumeration, such as a USB charger. In such a particular case, the SB11
solder bridge must be closed. ST-LINK/V2-1 turns the ST890 power switch ON regardless
of the enumeration procedure result and passes the power unconditionally to the board.

The LD8 green LED is lit whenever the whole board is powered.

8.6.8 Measurement of current consumption by the microcontroller

The JP2 jumper, labeled IDD, allows the consumption of the STM32L496AGI6 to be
measured directly by a built-in MCU current ammeter circuit capable of measuring from
60

nA to 50 mA or by removing the jumper and connecting an external ammeter.

8.7 Programming/debugging when the power supply is not from ST-LINK/V2-1

It is mandatory to power the board first using the user USB FS connector CN8 or the VIN pin
of the Arduino™ connector CN15 before connecting the USB cable from ST-LINK/V2-1 CN5
to the PC. Proceeding this way ensures that the enumeration succeeds thanks to the
external power source.

The following power sequence procedure must be respected:

1. Connect jumper JP7 on U5V pins to use power from user USB CN8 or on E5V pins to
use power from VIN of Arduino™ connector CN15.

2. Connect the corresponding external power source

3. Check that the LD8 green LED is turned ON

4. Connect the PC to ST-LINK/V2-1 USB connector CN5

Note1: the 3.3 V supply on ARD connector PIN4 is not a power input for
32L496GDISCOVERY board in order to keep the power architecture simple.

Note 2: The external voltage applied to pin VIN should be in the range of 6 V to 9 V at 25 °C
ambient temperature.The U10 regulator risks overheating and can be damaged if a higher
voltage is applied.

Note 3: By default pin 5 and pin 6 of connector CN16 are connected to MCU ports PC0 and
PA1 respectively. By default, they are enabled by the default configuration of solder bridges:
SB28 and SB26 closed, SB27 and SB25 opened. In case an I

2

C interface is needed on pins
5 and 6 of CN16 instead of ADC inputs, SB28 and SB26 must be opened and SB27 and
SB25 must be closed.

9.9 LCD display

The display is a 1.54-inch 240 x 240 pixels TFT color LCD with capacitive touch panel. It
can display up to 262
STM32L496AGI6 by the CN6 connector. By default, the solder bridge SB15 is opened and
the solder bridge SB14 is closed. It sets the IM of the LCD to high, enabling the LCD display
data bus in 16-bit mode. To use the LCD in 8-bit mode, SB15 must be closed and SB14
opened.

The selection of the LCD is performed by the FMC_NE1 (PD7) signal. The write enable
signal is FMC_NWE (PD5) and the read enable signal is FMC_NOE (PD4). The FMC
address A18 signal is used to select data/command access to the LCD.
