Evaluation board with STM32G4xxQE MCU
Introduction
The STM32G474E-EVAL board is a complete demonstration and development platform for
the STMicroelectronics Arm®Cortex®-M4 core-based STM32G474QET6 microcontroller. It
features three FDCAN controllers, four I²C Fast mode plus, five USART/UARTs and one
LPUART, four SPIs, one SAI port, USB FS and IRTIM communication interfaces, UCPD,
five 12-bit ADCs, seven 12-bit DAC channels, seven comparators, six operational
amplifiers, 17 timers, 96 Kbytes of internal SRAM, 32 Kbytes of CCM SRAM, 512 Kbytes of
flash memory, and JTAG/SWD debugging support.
The STM32G474E-EVAL, shown in Figure 1 and Figure 2, is used as a reference design for
user application development before porting to the final product. The STM32G484E-EVAL is
populated with an STM32G484QET6 MCU with cryptography. The STM32G474E-EVAL1 is
configured as a dedicated motor control board.
The full range of hardware features available on the board helps users to optimize the
application development by the evaluation of all the peripherals (USB FS, UCPD, USART,
audio, ADC and DAC, differential ADC, TFT LCD, potentiometer/LDR, SRAM, Quad-SPI
flash memory device, microSD™ card, smartcard, FDCAN transceiver, high-brightness
LED, motor control connectors, temperature sensor, and others). Extension headers provide
an easy connection to a daughterboard for specific applications.
STLINK-V3E is integrated into the board, as the embedded in-circuit debugger and
programmer for the STM32 MCU and the USB Virtual COM port bridge.
The three products (STM32G474E-EVAL, STM32G484E-EVAL, and STM32G474E-EVAL1)
are described in this user manual, together with STM32G474E-EVAL figures.

5.1 STLINK-V3E
STLINK-V3E facility for debugging and flashing of STM32G474QET6 is integrated on the
STM32G474E-EVAL board. It features:
•Self-powered through a USB connector (Micro-B)
•USB 2.0 high-speed compatible interface
•Direct firmware update support (DFU)
•SWD and serial wire viewer (SWV) communication support
•Drag-and-drop flash programming
•Two LEDs: communication, power
The CN21 USB connector can be used to power the STM32G474E-EVAL regardless of the
STLINK-V3E facility used for debugging or programming STM32G474QET6. This holds
also when the STLINK standalone tool is connected to the CN14, CN15, CN16, or CN17
connector and used for debugging or programming the STM32G474QET6. Section 5.3:
Power supply provides more detail about powering the STM32G474E-EVAL.
Refer to www.st.com for details about STLINK-V3E.
5.1.1 Drivers and firmware upgrade
The STLINK-V3E requires drivers to be installed on Windows®and embeds firmware that
needs to be updated from time to time to benefit from new functionality or corrections. Refer
to the technical note Overview of ST-LINK derivatives (TN1235) for details.
Before connecting the STM32G474E-EVAL to a Windows PC via USB, a driver for
STLINK-V3E must be installed. It is available from www.st.com.
5.2 ETM trace
The CN17 connector is available to output trace signals used for debugging. By default, the
Evaluation board is configured such that, STM32G474QET6 signals PE2, PE3, and PE4 are
connected to trace outputs TRACECLK, TRACED0, and TRACED1 of CN17, but these
signals are shared with the audio codec, motor control connectors, and FMC.
Table 3 shows the setting of configuration elements to shunt PE3 and PE4 MCU ports to the
CN17 connector, to use them as debug trace signals.
Table 4 shows the setting of configuration I/Os to shunt PE2, PE3, PE4, and PE5 MCU ports
to use them as the right functions.

Warning: Generally, we have one default setting for the best
performance of many shared features, but it is easy for users
to configure features, as we have many default settings for
MCU ports (solder bridge or resistor is soldered).
5.3 Power supply
The STM32G474E-EVAL board is designed to be powered by a 5 V DC power source. It
incorporates a precise PTC and TRANSIL to protect the board from damage due to a wrong
power supply. One of the following five 5 V DC power inputs can be used, upon appropriate
board configuration:
•CN25 power jack:
Marked PSU on the board (JP12 jumper setting on E5V on the silkscreen). The positive
pole is on the center pin as illustrated in Figure 22.
The external power supply from the CN25 power jack is from 5 to 18 V input voltage.
The dedicated DC/DC regulator ST1S41PHR is used for about 5.2 V output voltage
and provided up to 3 A current.
•CN21 USB Micro-B receptacle of STLINK-V3E with enumeration:
Up to 500 mA can be supplied to the board (JP12 jumper setting on STLK on the
silkscreen).
Offers the enumeration feature described in Section 5.3.1.
•CN21 USB Micro-B receptacle of STLINK-V3E without enumeration:
Up to 1000 mA can be supplied to the board directly without enumeration (JP12 jumper
setting on CHGR on the silkscreen).
•CN22 USB Type-C®receptacle of USB PD interface:
Marked TYPE-C on the board (JP12 jumper setting on U5V on the silkscreen). Up to
500 mA can be supplied to the board in this way.
•Pin 49 of CN5 and pin 49 of CN6 extension connectors for custom daughterboard:
Marked 5V_D on the board (JP12 jumper setting on D5V on the silkscreen).
The LD6 green LED turns on when the voltage on the power line marked as 5 V is present.
All supply lines required for the operation of the components on the STM32G474E-EVAL
are derived from that 5 V line.
Table 5 describes the settings of all jumpers related to powering the STM32G474E-EVAL
and extension board. VDD_MCU is STM32G474QET6 digital supply voltage line. It can be
connected to a fixed 3.3 V or with an adjustable voltage regulator controlled by the RV3
potentiometer and producing a range of voltages between 1.62 V and 3.6 V.

5.3.1 Supplying the board through the STLINK-V3E USB port
To power the STM32G474E-EVAL board, the USB host (a PC) gets connected to the Micro-
B USB receptacle of the STM32G474E-EVAL board via a USB cable. The connection event
starts the USB enumeration procedure. In its initial phase, the current supply capability of
the USB port on the host is limited to 100 mA. It is enough because only the STLINK-V3E
part of the STM32G474E-EVAL draws power at that time: the U25 STMPS2151 power
switch is set to the OFF position, which isolates the rest of the STM32G474E-EVAL from the
power source. In the next phase of the enumeration procedure, the host PC informs the
STLINK-V3E facility of its capability to supply current up to 300 mA. If the answer is positive,
the STLINK-V3E sets the U25 STMPS2151 switch to the ON position to supply power to the
rest of the STM32G474E-EVAL board. If the PC USB port is not capable of supplying
current up to 300 mA, the CN25 power jack is available to supply the board.
If a short circuit occurs on the board, the STMPS2151 power switch protects the USB port of
the host PC against a current demand exceeding 500 mA. In such an event, the LD7 LED
lights up.
The STM32G474E-EVAL board can also be supplied from a USB power source not
supporting enumeration, such as a USB charger. In this particular case, jumper JP12 must
be fitted with a jumper hat as shown in Table 5. STLINK-V3E bypasses STMPS2151 power
regardless of the enumeration procedure result and passes the power unconditionally to the
board.
The LD6 green LED turns on whenever the whole board is powered.
5.3.2 Using STLINK-V3E along with powering through the CN25 power jack
When the board requires a current higher than 300 mA, the host PC, connected to the
STLINK-V3E USB port for debugging or programming, cannot supply the
STM32G474QET6 MCU. In such a case, the board can be powered through CN25 (marked
PSU on the board).
To do this, it is important to power the board before connecting it with the host PC, which
requires the following sequence to be respected:
1. Set the jumper JP12 in the E5V position.
2. Connect the external power source to CN25.
3. Check that the green LED LD6 is turned on.
4. Connect the host PC to the CN21 USB connector.
Caution: In case the board requires more than 300 mA and the host PC is connected via USB before
the board is powered from CN25, the following risk events are possible (listed in reverse
severity order):
1. The host PC can supply 300 mA (the enumeration succeeds) but it features no over-
current protection on its USB port. It is damaged due to over-current.
2. The host PC can supply 300 mA (the enumeration succeeds) and it has built-in
over-current protection on its USB port, limiting or shutting down the power out of its
USB port when the excessive current demand from the STM32G474E-EVAL is
detected. This causes an operating failure of the STM32G474E-EVAL.
3. The host PC cannot supply 300 mA (the enumeration fails). The STLINK-V3E does not
supply the rest of the STM32G474E-EVAL from its USB port VBUS line.
Table 5 details the jumper and solder bridge settings used for the configuration of the power
supply of the STM32G474E-EVAL.
