UM2160User manualDiscovery kit with STM32L496AG MCUIntroductionThe 32L496GDISCOVERY Discovery kit is a complete demonstration and developmentplatform for the STMicroelectronics Arm Cortex -M4 core-based STM32L496AGI6microcontroller. Thanks to the innovative ultra-low-power-oriented features, extended RAM,and graphics performance (Chrom-ART Accelerator ) offered by the STM32L496AG, the32L496GDISCOVERY kit is designed to enable easy prototyping for many applications,including audio and graphics, with state-of-the-art energy efficiency. For even more userfriendliness, the on-board ST-LINK/V2-1 debugger provides out-of-the-box loading anddebugging capabilities. The microcontroller features the following interfaces: four I2Cs, threeSPIs, one SDIO, FMC, and Quad-SPI. It also features five USARTs, one ULP UART, twoCAN buses, three 12-bit ADCs, two 12-bit DACs, two SAIs, two ULP analog comparators,two Op-Amps, LCD 8 40 or 4 44 with step-up converter, four digital filters for sigma-deltamodulator and SWP, 8- to 14-bit camera interface, USB 2.0 OTG FS, JTAG and SWDdebugging support. This 32L496GDISCOVERY Discovery kit offers everything required forusers to get started quickly and develop applications easily.The full range of hardware features on the board helps users to evaluate almost allperipherals (USB OTG FS, microSD card, 8-bit camera, 8-Mbit PSRAM, IDDmeasurement, full-duplex I2S with an audio CODEC and stereo jack for headset includinganalog microphone, DFSDM with a pair of MEMS digital microphones on board, Quad-SPIflash memory device, 1.54-inch TFT LCD using FMC interface with capacitive touch paneland others) and develop applications. ARDUINO Uno V3, Pmod ; and STMod connectors allow easy connection of extension shields or daughterboards for specificapplications.The integrated ST-LINK/V2-1 provides an embedded in-circuit debugger and programmer forthe STM32 MCU.The 32L496GDISCOVERY Discovery kit comes with the STM32 comprehensive softwareHAL library and LL APIs together with various packaged software examples.Figure 1. 32L496GDISCOVERY (top view)Figure 2. 32L496GDISCOVERY (bottom view)1.

Hardware layout and configuration6.3UM2160Embedded ST-LINK/V2-1The ST-LINK/V2-1 programming and debugging tool is integrated on the32L496GDISCOVERY 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 USBThese features are no more supported on ST-LINK/V2-1: SWIM interface Application voltage lower than 3VFor general information concerning the debugging and programming features that arecommon to both versions V2 and V2-1, refer to ST-LINK/V2 in-circuit debugger/programmerfor STM8 and STM32 User manual (UM1075).6.3.1DriversBefore connecting the 32L496GDISCOVERY board to a Windows PC via USB, a driver forST-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, theassociation of “Unknown” USB devices found on the 32L496GDISCOVERY board to thisdedicated driver, must be manually updated in the device manager.Note:It is recommended to proceed using USB Composite Device, as shown in Figure 7.Figure 7.

UM21606.3.2Hardware layout and configurationST-LINK/V2-1 firmware upgradeThe ST-LINK/V2-1 embeds a firmware upgrade mechanism for the in-situ upgrade with theUSB port. As the firmware may evolve during the lifetime of the ST-LINK/V2-1 product likenew functionality, bug fixes, or support for new microcontroller families, it is recommendedto visit the www.st.com website before starting to use the 32L496GDISCOVERY board andperiodically, to stay up-to-date with the latest firmware version.6.4Low power consumption stateThe 32L496GDISCOVERY board can be set in a low-power state with a maximum currentkept below 20 μA at 5 V.The low-power mode is reached when the following conditions are satisfied:6.51.The connections between the ST-LINK/V2-1 and the MCU are manually disconnectedwith the microswitch SW1. This especially controls the four pull-ups on RST, the pull-upon SWDIO, and the VDD and 5 V detection circuits.2.The peripherals (Including LCD, CTP, and PSRAM) are unpowered with the MOSFETthat is controlled by the PH0 signal of STM32L496AGI6.3.The JP8 jumper is OFF so that the 5-V power LED is powered down.4.Peripherals are setup by FW to reach the power-down modea)Set QSPI to low-power modeb)Set MFX to sleep modec)Remove the microSD card from the socketd)Set all the audio lines to lowTAG and SWDOne TAG interface footprint is reserved on the 32L496GDISCOVERY board. It can be usedto debug and program the on-board MCU.One 6-pin header was added to the 32L496GDISCOVERY board. This header connects tothe on-board ST-LINK SWD that can be used to debug and program an external MCU. Insuch a configuration, the VDD power supply from the external board can be either 1.8 V or3.3 V thanks to the on-board voltage converter.Table 4 describes the use of the JP6 jumper for selecting between on-board and externalMCU.UM2160 Rev 315/4746

A jumper must be placed at the 1V8 location of JP5 (connecting pins 2 and 3) tosupply 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.6.6.7Supplying the board with ST-LINK/V2-1 USBIn this mode, the USB host (a PC) is connected to the standard Micro-B USB receptacle ofthe 32L496GDISCOVERY board with a USB cable. The connection event starts the USBenumeration procedure.In the initial phase of the enumeration procedure, the current supply capability of the USBport of the host is limited to 100 mA. This value is high enough for normal operation sinceonly the ST-LINK/V2-1 part of 32L496GDISCOVERY draws power during that phase. If theSB11 solder bridge is OFF in the default configuration, the ST890 power switch (U7) is setto 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/V2-1facility of its capability to supply up to 500 mA. If this is accepted, the ST-LINK/V2-1 sets theST890 switch (U7) to the ON position to supply power to the rest of the32L496GDISCOVERY board. If the P
