ST STM32L562E-DK User manual

Introduction
The STM32L562E-DK Discovery kit is designed as a complete demonstration and development platform for the
STMicroelectronics Arm® Cortex®-M33 core-based STM32L562QEI6Q 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 TFT-LCD 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 SPIs, one CAN‑FD port, one SDMMC interface, 2x 12-bit ADC, 2x 12-bit
DAC, two low-power comparators, four 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 fanout 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 an embedded in-circuit debugger and programmer for the STM32 MCU and the
USB Virtual COM port bridge.

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 the STDC14/MIPI10 connector (CN8)
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 USB connector (CN17)
• USB 2.0 high-speed-compatible interface
• JTAG and Serial Wire Debug (SWD) specific features:
– 3 to 3.6 V application voltage on the JTAG/SWD interface and 5 V tolerant inputs
– JTAG
– SWD and Serial Wire Viewer (SWV) communication
• STDC14 (MIPI10) compatible connector (CN8)
• COM status LED (LD3) which blinks during communication with the PC
• OC fault red LED (LD11) alerting on USB overcurrent request
• 5 V/500 mA output power supply capability (U47) with current limitation and LED (LD11)
• 5 V power green LED (LD12)
Table 4 describes the USB Micro-B connector (CN17) pinout.

6.1.2 Drivers
Before connecting the STM32L562E-DK board to a Windows PC via USB, the user must install a driver for
STLINK-V3E (not required since 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 might 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 bridge functions
6.1.3 STLINK-V3E firmware upgrade
The STLINK-V3E embeds a firmware upgrade mechanism for in‑place upgrades through the USB port. The
firmware might evolve during the lifetime of the STLINK-V3E product (for example new functionalities, bug fixes,
support for new microcontroller families). 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
Two 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 the STDC14/MIPI10 debug connector (CN8).
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 the RESET state and all GPIOs are in high impedance. Then the user can
connect the external debug tool to the debug connector (CN8).
