8.3 Embedded ST-LINK/V2-1

The ST-LINK/V2-1 programming and debugging tool is integrated on the 32L496GDISCOVERY board. Compared to ST-LINK/V2 the changes are listed below.

The new features supported on ST-LINK/V2-1 are:

• USB software re-enumeration

• Virtual COM port interface on USB

• Mass storage interface on USB

• USB power management request for more than 100mA power on USB

These features are no more supported on ST-LINK/V2-1:

• SWIM interface

• Application voltage lower than 3V

For general information concerning the debugging and programming features that are common to both versions V2 and V2-1, refer to ST-LINK/V2 in-circuit debugger/programmer for STM8 and STM32 User manual (UM1075).

8.3.1 Drivers

Before connecting the 32L496GDISCOVERY board to a Windows® 7, Windows® 8 or Windows® XP PC via USB, a driver for ST-LINK/V2-1 must be installed. It can be downloaded from the www.st.com website.

In case the 32L496GDISCOVERY board is connected to the PC before installing the driver, the PC device manager may report some 32L496GDISCOVERY board interfaces as “Unknown”. To recover from this situation, after installing the dedicated driver, the association of “Unknown” USB devices found on the 32L496GDISCOVERY board to this dedicated driver, must be manually updated in the device manager.

Note: It is recommended to proceed using USB Composite Device, as shown in Figure 7.

8.3.2 ST-LINK/V2-1 firmware upgrade

The ST-LINK/V2-1 embeds a firmware upgrade mechanism for in-situ upgrade through the USB port. As the firmware may evolve during the life time of the ST-LINK/V2-1 product (for example a new functionality, bug fixes, support for new microcontroller families), it is recommended to visit the www.st.com website before starting to use the 32L496GDISCOVERY board and periodically, to stay up-to-date with the latest firmware version.

8.4 Low power consumption state

The 32L496GDISCOVERY board can be set in a low-power state with a maximum current kept below 20 μA at 5 V.

The low-power mode is reached when the following conditions are satisfied:

1. The connections between the ST-LINK/V2-1 and the MCU are manually disconnected by means of the micro switch SW1. This especially controls the for pull-up on RST, the pull-up on SWDIO, the VDD detection circuit and the 5 V detection circuit.

2. The peripherals (including LCD, CTP and PSRAM) are unpowered by means of the MOSFET that is controlled by the PH0 signal of STM32L496AGI6.

3. Jumper JP8 is disconnected so that the 5-V power LED is powered down.

4. Peripherals are setup by FW to reach the power down mode

a) Set QSPI to low-power mode

b) Set MFX to sleep mode

c) Remove the microSD™ card from the socket

d) Set all the audio lines to low

8.5 TAG and SWD

One TAG interface footprint is reserved on the 32L496GDISCOVERY board. It can be used to debug and program the on-board MCU.

One 6-pin header was added to the 32L496GDISCOVERY board. This header connects to the on board ST-LINK SWD that can be used to debug and program an external MCU. In such a configuration, the VDD power supply from the external board can be either 1.8 V or 3.3 V thanks to the on-board voltage converter.

Table 2 describes the use of jumper JP6 for selecting between on-board and external MCU.


16/61 DocID030176 Rev 1

8.6 Power supply

The 32L496GDISCOVERY board is designed to be powered by a selection of sources according to the position of jumper JP7 as described in Table 3.

Note: The Discovery board must be powered by a power supply unit or by an auxiliary equipment complying with the standard EN-60950-1: 2006+A11/2009, and must be Safety Extra Low Voltage (SELV) with limited power capability.

8.6.1 Supplying the board through ST-LINK/V2-1 USB connector CN5

In this mode, STLK from the CN5 ST-LINK/V2-1 USB connector is used. The corresponding setting is described in Table 4. The LD8 green LED is on to confirm the presence of 5 V supply.

8.6.6 MCU power supply options

The 32L496GDISCOVERY board offers the possibility to supply the MCU with 1.8 V or 3.3 V. A jumper must be placed at the 1V8 location of JP5 (connecting pins 2 and 3) to supply the MCU with 1.8 V,. The jumper must be placed at the 3V3 location of JP5 (connecting pins 1 and 2) to supply the MCU with 3.3 V.

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 mA, 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.

It needs the MCU run SW to let this current test circuit get into low power mode.

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

If this order is not respected, the 32L496GDISCOVERY board may be powered by VBUS first from ST-LINK and the following risks may be encountered:

1. If more than 500 mA current is needed by the board, the PC may be damaged or the current can be limited by the PC. As a consequence the board is not powered correctly.

2. 500 mA is requested at enumeration: if the PC cannot provide such current, there is a risk that the request is rejected and that the enumeration does not succeed.

8.8 Clock source

One clock source is available as described below:

• X1, 32-kHz crystal for STM32L496AGI6 embedded RTC

8.9 Reset sources

The reset signal of the 32L496GDISCOVERY board is active low and the reset sources include:

• Reset button B1

• Arduino™ Uno V3 shield board from CN15

• Embedded ST-LINK/V2-1

8.10 Boot configuration

The boot configuration of the STM32L496AGI6 microcontroller is controlled by the BOOT0 signal on pin PH3.

BOOT0 is by default grounded through the R20 pull-down resistor.

It is possible to set BOOT0 high by removing resistor R20 and soldering resistor R21.


22/61 DocID030176 Rev 1

8.11 Audio codec

An audio codec CS42L51-CNZ from Cirrus (U18) is connected to the SAI1 interface of the STM32L496AGI6. It communicates with STM32L496AGI6 via an I2C bus and offers the possibility to connect a stereo headphone or a headset with a mono analog microphone.

The I2C-bus address of CS42L51-CNZ is 94h.

8.12 Stereo headset and headphone jack

A stereo headphone or a stereo headset with analog microphone can be plugged into the 3.5 mm standard jack socket CN12.

If a headset is plugged into CN12, the bias of the microphone is driven by the output MICBIAS1 of the codec and the analog audio enters the codec by pin AIN3A.

8.13 DFSDM

Two STMicroelectronics MP34DT01TR MEMs digital microphones U1 and U2 are available on the 32L496GDISCOVERY board. The two microphones are separated by a distance of 21 mm. The microphones are connected to the DFSDM of the STM32L496AGI6 by the port PC2 generating the clock and by the port PC7 collecting the PDM interleaved data. Both are powered by MIC_VDD (PH1 of STM32L496AGI6).

8.14 USB OTG FS

The 32L496GDISCOVERY board supports USB OTG full speed communication via a USB Micro-AB connector (CN8) and USB power switch (U14) connected to VBUS.

The LD6 green LED is lit in one of these cases:

• Power switch (U14) is ON and the 32L496GDISCOVERY board works as a USB host

• VBUS is powered by another USB host when the 32L496GDISCOVERY board works as a USB device.

The LD7 red LED is lit in case of overcurrent.

Note 1: When the 32L496GDISCOVERY board is powered by the ST-LINK then the OTG function provides up to 100 mA.

Note 2: When the 32L496GDISCOVERY board is powered by an external power supply then the OTG function provides more than 100 mA, according to the external power supply capability.

Note 3: When the 32L496GDISCOVERY board is powered by an external power supply through USB FS connector (CN8), in device mode, do not use a PC as power source (refer to Section 8.6.3).

8.14.1 32L496GDISCOVERY as an USB Device

When the 32L496GDISCOVERY board is used as a USB Device, the board can be powered by the 5 V DC of the USB OTG FS connection (jumper JP7 connecting pins 5 and 6).

DocID030176 Rev 1 23/61


60

The LD6 VBUS and LD8 PWR green LEDs are lit to confirm the 5 V presence.

8.14.2 32L496GDISCOVERY as an USB Host

When the 32L496GDISCOVERY board is used as a USB Host, it supplies the 5 V for the USB peripheral using one of the following sources:

• ST-LINK/V2-1 USB Micro-B connector CN5 when a jumper connects the pins at the STLK location of JP7.

• An external 5 V source connected to pin 5 of the extension connector CN15 when a jumper connects the pins at the ARD location of JP7.

• An external source between 7 V and 11 V connected to the VIN pin of the Arduino™ connector CN15 when a jumper connects the pins at the E5V location of JP7.

The LD8 green LED is lit to confirm the presence of the 5 V source.

The STMPS2141STR power switch is controlled by port MFX_GPIO3 to deliver the 5 V power to the USB Device connected to the USB connector CN8. When MFX_GPIO3 is pulled down to ground, the power switch is closed, and the LD6 green LED confirms the 5 V to the USB Device. The LD7 FAULT red LED is lit in case of over-current.

For more details refer to Section 8.6: Power supply on page 16.

8.15 PSRAM memory

An 8-Mbit PSRAM is connected to the NOR_RAM of the FMC interface of the STM32L496AGI6. The data bus is shared with the LCD.

Note: The PSRAM is only working when the STM32L496AGI6 is supplied with 3.3 V.

8.16 Quad-SPI Flash memory

A 64-Mbit Quad-SPI Flash memory (MX25R6435FM2IL0 from MACRONIX) is connected to the Quad-SPI interface of the STM32L496AGI6.

8.17 Virtual COM port

The serial interface USART2 is directly available as a virtual COM port of the PC connected to the ST-LINK/V2-1 USB connector CN5. The virtual COM port settings are configured as: 115200 b/s, 8-bit data, no parity, 1 stop bit, no flow control.

8.18 Joystick and LEDs

The blue button B2 is a four-direction joystick with a selection mode when pressed in the center. The logic state is high when one of the five-position switch (Left, Right, Up, Down, Selection) is pressed. The center position is connected to a wake-up pin of the microcontroller PC13. This offers the possibility to wake-up the microcontroller by pressing the center of the joystick.

Two LEDs located near camera connectors CN1 are available for the user. Refer to Figure 4: 32L496GDISCOVERY top layout on page 11 for details. The LEDs are LD1, LD2,

9.1 Arduino™ Uno V3 compatible connectors

CN10, CN11, CN15, and CN16 are female connectors compatible with Arduino™ Uno V3 standard. Most shields designed for Arduino™ Uno V3 are also supported by the 32L496GDISCOVERY board.

The Arduino™ connectors on the 32L496GDISCOVERY board support the Arduino™ Uno V3.

There are three possible power sources for VREF+:

• From the 32L496GDISCOVERY board VDDA. The related jumper settings are detailed in Table 11. In this case, a 0 Ω resistor must be mounted on R18.

Warning: There is a high leakage and a risk of damage in the following configuration: VDDA = VDD_MCU = 1.8 V and 3.3V connected to ADC input IO.

• From an external shield through Arduino™ connector CN10. In this case, a 0 Ω resistor must be mounted on SB2 and a 100 nF capacitor must be mounted on C3.

• From the STM32L496AGI6 MCU (default).

Caution: The I/Os of STM32 microcontroller are 3.3 V compatible instead of 5 V for Arduino™ Uno V3.

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 I2C 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 Kcolors. The LCD parallel interface is connected to the FMC of the 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.

The PH7 port must be used as an input of the microcontroller connected to the LCD signal TE (Tearing Effect). The TE signal is used to synchronize the refresh of the LCD memory by the microcontroller with the LCD scan. Such a synchronization allows to avoid visible artifacts on the display.

9.10 Backlight

The LEDK and LEDA signals of the LCD module are the cathode and anode of the backlight LEDs.

The backlight LEDs require a current source supply of typically 15 mA capable to deliver a voltage up to 10 V. This function is handled by the backlight driver circuit STLD40DPUR that is a switching mode boost converter powered by the 5 V rail of the board.

A high level of the LCD_BLCTRL (PI0) signal switches the backlight on. It is possible to dim backlight intensity by applying a low frequency PWM signal to LCD_BLCTRL (from 1 kHz to 10 kHz typically).

9.11 Touch panel

The touch panel is a capacitive touch panel using an I2C interface. The CN13 10-pin connector of the touch panel is located on th bottom side of the 32L496GDISCOVERY board. The I2C SDA line is connected to PB14 and the I2C SCL line is connected to PH4. The CTP_INT interrupt output is connected to port PG14 as an interruption input of the microcontroller. Port MFX_GPIO1 is the reset of the capacitive touch panel.

9.12 ST-LINK/V2-1 USB Micro-B connector CN5

USB connector CN5 is used to connect embedded ST-LINK/V2-1 to PC for t h e programming and the debugging of the STM32L496AGI6 microcontroller.

Appendix C PMOD and STMod+ schematic table

Table 24 gives the description of the signals available on the STMod+ connector. It also shows which signal is shared with other board connectors (such as PMOD or Arduino™ Uno V3 as listed in columns PMOD and ARD respectively). When the I2C bus (pins 7 and 10) is shared with built-in discovery slave devices, it is recommended to check the device slave address when adding it to the bus. Refer to the following list of acronyms before reading Table 24:

• NSS2 stands for SPI2_NSS

• LT2.O stands for LPTIM2_OUT

• LT1.2 stands for LPTIM1_IN2

• LT1.E stands for LPTIM1_ETR

• T15.2 stands for TIM15 CH2

• SCL4 stands for I2C4_SCL

• SDA1 stands for I2C1_SDA

• DFS1.D5 stands for DFSDM1_DATIN5

• DFS1.CI2 stands for DFSDM1_CKIN2

• DFS1.CO stands for DFSDM1_CKOUT

• RX1 stands for USART1_RX

• UCK3 stands for USART3_CK

• CTS2 stands for USART2_CTS

• LRTS1 stands for LPUART_RTS1

• CRX1 stands for CAN1_RX
