ST STM32L562E-DK User manual

Introduction
The STM32L562E-DK Discovery kit is designed as a complete demonstration and development platform for STMicroelectronics
Arm® Cortex®-M33 core-based STM32L562QEI6QU microcontroller with TrustZone®. It features 256 Kbytes of internal SRAM
and 512 Kbytes of internal Flash memory, one flexible memory controller (FMC) interface, one Octo-SPI memory interface, one
LCD-TFT controller, one RTC, up to 16 timers, one USB Type-C™ device FS port with UCPD controller, two SAI ports, four I²C
buses, six USART ports, three SPI, one CAN-FD port, one SDMMC interface, 2x 12-bit ADC, 2x 12-bit DAC, 2 low-power
comparators, 4 digital filters for sigma-delta modulation, touch-sensing capability, an embedded step down converter, and JTAG
and ETM debugging support.
STM32L562E-DK, shown in Figure 1, associated with the fan-out expansion board, is used as a reference design for user
application development, although it is not considered as the final application.
The full range of hardware features on the board helps the user to evaluate all the peripherals (USB, USART, digital
microphones, ADC and DAC, TFT LCD, Octo-SPI Flash memory device, microSD™ card, audio codec, joystick, user button,
Bluetooth® Low Energy, accelerometer and gyroscope) and to develop applications. Extension headers allow easy connection
of a daughterboard or wrapping board for a specific application.
An STLINK-V3E is integrated on the board, as embedded in-circuit debugger and programmer for the STM32 MCU and the
USB Virtual COM port bridge.

2.1 Product marking
Evaluation tools marked as “ES” or “E” are not yet qualified and therefore not ready to be used as reference
design or in production. Any consequences deriving from such usage will not be at ST charge. In no event, ST will
be liable for any customer usage of these engineering sample tools as reference designs or in production.
“E” or “ES” marking examples of location:
• On the targeted STM32 that is soldered on the board (For an illustration of STM32 marking, refer to the
STM32 datasheet “Package information” paragraph at the www.st.com website).
• Next to the evaluation tool ordering part number that is stuck or silk-screen printed on the board.
Some boards feature a specific STM32 device version, which allows the operation of any bundled commercial
stack/library available. This STM32 device shows a "U" marking option at the end of the standard part number
and is not available for sales.
In order to use the same commercial stack in his application, a developer may need to purchase a part number
specific to this stack/library. The price of those part numbers includes the stack/library royalties.
2.2 Codification
The meaning of the codification is explained in Table 2. The order code is mentioned on a sticker placed on the
top side of the board.

6.1 Embedded STLINK-V3E
6.1.1 Description
There are two different ways to program and debug the onboard STM32 MCU:
• Using the embedded STLINK-V3E
• Using an external debug tool connected to CN8 STDC14/MIPI-10 connector
The STLINK-V3E facility for debugging and flashing is integrated into the STM32L562E-DK Discovery kit.
The STLINK-V3E makes the STM32L562E-DK Discovery kitArm® Mbed Enabled™.
The embedded STLINK-V3E supports only SWD and VCP for STM32 devices.
Features supported in STLINK-V3E:
• 5 V power supplied by the CN17 USB connector
• USB 2.0 high-speed-compatible interface
• JTAG and serial wire debugging (SWD) specific features:
– 3 to 3.6 V application voltage on the JTAG/SWD interface and 5V tolerant inputs
– JTAG
– SWD and serial viewer (SWV) communication
• Direct firmware update feature (DFU) (CN6)
• STDC14 (MIPI10) compatible connector (CN8)
• LD3 status LED (COM) which blinks during communication with the PC
• LD11 fault red LED (OC) alerting on USB overcurrent request
• 5 V / 500 mA output power supply capability (U47) with current limitation and LD11 LED
• 5 V power green LD12 LED (5V)
Table 4 describes the CN17 USB Micro-B connector pinout.

6.1.2 Drivers
Before connecting the STM32L562E-DK board to a Windows PC via USB, the user must install a driver for the
STLINK-V3E (not required for Windows 10). It is available on the www.st.com website.
In case the STM32L562E-DK board is connected to the PC before the driver is installed, some STM32L562E-DK
interfaces may be declared as “Unknown” in the PC device manager. In this case, the user must install the
dedicated driver files, and update the driver of the connected device from the device manager as shown in
Figure 5.
Note: Prefer using the USB Composite Device handle for a full recovery.

• 374F for STLINK-V3E with bridges functions
6.1.3 STLINK-V3E firmware upgrade
The STLINK-V3E embeds a firmware upgrade mechanism for in-situ upgrades through the USB port. As the
firmware may evolve during the lifetime of the STLINK-V3E product (for example new functionalities, bug fixes,
support for new microcontroller families), it is recommended to visit the www.st.com website before starting to use
the STM32L562E-DK Discovery kit and periodically, to stay up-to-date with the latest firmware version.
6.1.4 Using an external debug tool to program and debug the onboard STM32
There are 2 basic ways to support an external debug tool:
1. Keep the embedded STLINK-V3E running. Power on the STLINK-V3E at first until the COM LED lights RED.
Then connect the external debug tool through CN8 STDC14/MIPI-10 debug connector.
2. Set the embedded STLINK-V3E in a high impedance state. When setting the jumper JP6 (STLK_RST) ON,
the embedded STLINK-V3E is in RESET state and all GPIOs are in high impedance. Then the user can
connect his external debug tool on the debug connector CN8.
