The STM32G473xB/xC/xE devices are based on the high-performance Arm Cortex -M4
32-bit RISC core. They operate at a frequency of up to 170 MHz.
The Cortex-M4 core features a single-precision floating-point unit (FPU), which supports all
the Arm single-precision data-processing instructions and all the data types. It also
implements a full set of DSP (digital signal processing) instructions and a memory protection
unit (MPU) which enhances the application’s security.
These devices embed high-speed memories (512 Kbytes of Flash memory, and 128 Kbytes
of SRAM), a flexible external memory controller (FSMC) for static memories (for devices
with packages of 100 pins and more), a Quad SPI Flash memory interface, and an
extensive range of enhanced I/Os and peripherals connected to two APB buses, two AHB
buses and a 32-bit multi-AHB bus matrix.
The devices also embed several protection mechanisms for embedded Flash memory and
SRAM: readout protection, write protection, securable memory area and proprietary code
readout protection.
The devices embed peripherals allowing mathematical/arithmetic function acceleration
(CORDIC for trigonometric functions and FMAC unit for filter functions).
They offer five fast 12-bit ADCs (5 Msps), seven comparators, six operational amplifiers,
seven DAC channels (3 external and 4 internal), an internal voltage reference buffer, a low-
power RTC, twothree general-purpose 32-bit timers, three 16-bit PWM timers dedicated to
motor control, seven general-purpose 16-bit timers, and one 16-bit low-power timer.
They also feature standard and advanced communication interfaces such as:

The devices operate in the -40 to +85 °C (+105 °C junction) and -40 to +125 °C (+130 °C
junction) temperature ranges from a 1.71 to 3.6 V power supply. A comprehensive set of
power-saving modes allows the design of low-power applications.
Some independent power supplies are supported including an analog independent supply

development by using metalanguage development tools to avoid saturation.
With its embedded Arm core, the STM32G473xB/xC/xE family is compatible with all Arm
tools and software.

Adaptive real-time memory accelerator (ART accelerator)
The ART accelerator is a memory accelerator that is optimized for the STM32 industry-
®
®
standard Arm Cortex -M4 processors. It balances the inherent performance advantage of
®
®
the Arm Cortex -M4 over Flash memory technologies, which normally requires the
processor to wait for the Flash memory at higher frequencies.
Memory protection unit
The memory protection unit (MPU) is used to manage the CPU accesses to the memory
and to prevent one task to accidentally corrupt the memory or the resources used by any
other active task. This memory area is organized into up to 8 protected areas, which can be
divided in up into 8 subareas each. The protection area sizes range between 32 bytes and
the whole 4 gigabytes of addressable memory.
The MPU is especially helpful for applications where some critical or certified code has to be
protected against the misbehavior of other tasks. It is usually managed by an RTOS (real-
time operating system). If a program accesses a memory location that is prohibited by the
MPU, the RTOS can detect it and take action. In an RTOS environment, the kernel can
dynamically update the MPU area setting based on the process to be executed.
The MPU is optional and can be bypassed for applications that do not need it.

Embedded Flash memory
The STM32G473xB/xC/xE devices feature 512 kbytes of embedded Flash memory which is
available for storing programs and data.
The Flash interface features:
–
–
Single or dual bank operating modes
Read-while-write (RWW) in dual bank mode
This feature allows to perform a read operation from one bank while an erase or program
operation is performed to the other bank. The dual bank boot is also supported.
Flexible protections can be configured thanks to the option bytes:
• Readout protection (RDP) to protect the whole memory. Three levels of protection are
available:
– Level 0: no readout protection
– Level 1: memory readout protection; the Flash memory cannot be read from or written
to if either the debug features are connected or the boot in RAM or bootloader are
selected
– Level 2: chip readout protection; the debug features (Cortex-M4 JTAG and serial
wire), the boot in RAM and the bootloader selection are disabled (JTAG fuse). This
selection is irreversible.
•
•
Write protection (WRP): the protected area is protected against erasing and
programming.
Proprietary code readout protection (PCROP): a part of the Flash memory can be
protected against read and write from third parties. The protected area is execute-only
and it can only be reached by the STM32 CPU as an instruction code, while all other
accesses (DMA, debug and CPU data read, write and erase) are strictly prohibited. An
additional option bit (PCROP_RDP) allows to select if the PCROP area is erased or not
when the RDP protection is changed from Level 1 to Level 0.
•
Securable memory area: a part of Flash memory can be configured by option bytes to
be securable. After reset this securable memory area is not secured and it behaves like
the remainder of main Flash memory (execute, read, write access). When secured, any
access to this securable memory area generates corresponding read/write error.
Purpose of the Securable memory area is to protect sensitive code and data (secure
keys storage) which can be executed only once at boot, and never again unless a new
reset occurs.
The Flash memory embeds the error correction code (ECC) feature supporting:
•
•
•
•
Single error detection and correction
Double error detection
The address of the ECC fail can be read in the ECC register
1 Kbyte (128 double word) OTP (one-time programmable) bytes for user data. The
OTP area is available in Bank 1 only. The OTP data cannot be erased and can be
written only once.

Embedded SRAM
STM32G473xB/xC/xE devices feature 128 Kbytes of embedded SRAM. This SRAM is split
into three blocks:
•
80 Kbytes mapped at address 0x2000 0000 (SRAM1). The CM4 can access the
SRAM1 through the System Bus. The first 32 Kbyte of SRAM1 support hardware parity
check.
•
•
16 Kbytes mapped at address 0x2001 4000 (SRAM2). The CM4 can access the
SRAM2 through the System bus. SRAM2 can be retained in standby modes.
32 Kbytes mapped at address 0x1000 0000 (CCM SRAM). It is accessed by the CPU
through I-Code/D-Code bus for maximum performance.
It is also aliased at 0x2001 8000 address to be accessed by all masters (CPU, DMA1,
DMA2) through SBUS contiguously to SRAM1 and SRAM2. The CCM SRAM supports
hardware parity check and can be write-protected with 1 Kbyte granularity.
•
The memory can be accessed in read/write at max CPU clock speed with 0 wait states.
3.6
Multi-AHB bus matrix
The 32-bit multi-AHB bus matrix interconnects all the masters (CPU, DMAs) and the slaves
(Flash memory, RAM, FSMC, QUADSPI, AHB and APB peripherals). It also ensures a
seamless and efficient operation even when several high-speed peripherals work
simultaneously.

Boot modes
At startup, a BOOT0 pin (or nBOOT0 option bit) and an nBOOT1 option bit are used to
select one of three boot options:
•
•
•
Boot from user Flash
Boot from system memory
Boot from embedded SRAM
The BOOT0 value may come from the PB8-BOOT0 pin or from an nBOOT0 option bit
depending on the value of a user nBOOT_SEL option bit to free the GPIO pad if needed.
The boot loader is located in the system memory. It is used to reprogram the Flash memory
by using USART, I2C, SPI, and USB through the DFU (device firmware upgrade).

CORDIC
The CORDIC provides hardware acceleration of certain mathematical functions, notably
trigonometric, commonly used in motor control, metering, signal processing and many other
applications.
It speeds up the calculation of these functions compared to a software implementation,
allowing a lower operating frequency, or freeing up processor cycles in order to perform
other tasks.

Filter mathematical accelerator (FMAC)
The filter mathematical accelerator unit performs arithmetic operations on vectors. It
comprises a multiplier/accumulator (MAC) unit, together with address generation logic,
which allows it to index vector elements held in local memory.
The unit includes support for circular buffers on input and output, which allows digital filters
to be implemented. Both finite and infinite impulse response filters can be realized.
The unit allows frequent or lengthy filtering operations to be offloaded from the CPU, freeing
up the processor for other tasks. In many cases it can accelerate such calculations
compared to a software implementation, resulting in a speed-up of time critical tasks.

Cyclic redundancy check calculation unit (CRC)
The CRC (cyclic redundancy check) calculation unit is used to get a CRC code using a
configurable generator with polynomial value and size.
Among other applications, the CRC-based techniques are used to verify data transmission
or storage integrity. In the scope of the EN/IEC 60335-1 standard, they offer a mean to verify
the Flash memory integrity.
The CRC calculation unit helps to compute a signature of the software during runtime, which
can be ulteriorly compared with a reference signature generated at link-time and which can
be stored at a given memory location.

Power supply supervisor
The device has an integrated ultra-low-power brown-out reset (BOR) active in all modes
(except for Shutdown mode). The BOR ensures proper operation of the device after power-
on and during power down. The device remains in reset mode when the monitored supply
voltage V is below a specified threshold, without the need for an external reset circuit.
DD
The lowest BOR level is 1.71 V at power on, and other higher thresholds can be selected
through option bytes.The device features an embedded programmable voltage detector
(PVD) that monitors the V power supply and compares it to the VPVD threshold. An
DD
interrupt can be generated when V drops below the VPVD threshold and/or when V is
DD
DD
higher than the VPVD threshold. The interrupt service routine can then generate a warning
message and/or put the MCU into a safe state. The PVD is enabled by software.
In addition, the device embeds a peripheral voltage monitor which compares the
independent supply voltages V
, with a fixed threshold in order to ensure that the
DDA
peripheral is in its functional supply range.
3.11.3
Voltage regulator
Two embedded linear voltage regulators, main regulator (MR) and low-power regulator
(LPR), supply most of digital circuitry in the device. The MR is used in Run and Sleep
modes. The LPR is used in Low-power run, Low-power sleep and Stop modes. In Standby
and Shutdown modes, both regulators are powered down and their outputs set in high-
impedance state, such as to bring their current consumption close to zero.
The device supports dynamic voltage scaling to optimize its power consumption in Run
mode. the voltage from the main regulator that supplies the logic (VCORE) can be adjusted
according to the system’s maximum operating frequency.
The main regulator (MR) operates in the following ranges:
•
•
•
Range 1 boost mode with the CPU running at up to 170 MHz.
Range 1 normal mode with CPU running at up to 150 MHz.
Range 2 with a maximum CPU frequency of 26 MHz.

3.11.4
Low-power modes
By default, the microcontroller is in Run mode after system or power Reset. It is up to the
user to select one of the low-power modes described below:
•
Sleep mode: In Sleep mode, only the CPU is stopped. All peripherals continue to
operate and can wake up the CPU when an interrupt/event occurs.
•
Low-power run mode: This mode is achieved with VCORE supplied by the low-power
regulator to minimize the regulator's operating current. The code can be executed from
SRAM or from Flash, and the CPU frequency is limited to 2 MHz. The peripherals with
independent clock can be clocked by HSI16.
•
•
Low-power sleep mode: This mode is entered from the low-power run mode. Only the
CPU clock is stopped. When wakeup is triggered by an event or an interrupt, the
system reverts to the Low power run mode.
Stop mode: In Stop mode, the device achieves the lowest power consumption while
retaining the SRAM and register contents. All clocks in the VCORE domain are
stopped. The PLL, as well as the HSI16 RC oscillator and the HSE crystal oscillator are
disabled. The LSE or LSI keep running. The RTC can remain active (Stop mode with
RTC, Stop mode without RTC). Some peripherals with wakeup capability can enable
the HSI16 RC during Stop mode, so as to get clock for processing the wakeup event.
•
Standby mode: The Standby mode is used to achieve the lowest power consumption
with brown-out reset, BOR. The internal regulator is switched off to power down the
VCORE domain. The PLL, as well as the HSI16 RC oscillator and the HSE crystal
oscillator are also powered down. The RTC can remain active (Standby mode with
RTC, Standby mode without RTC). The BOR always remains active in Standby mode.
For each I/O, the software can determine whether a pull-up, a pull-down or no resistor
shall be applied to that I/O during Standby mode. Upon entering Standby mode, SRAM
and register contents are lost except for registers in the RTC domain and standby
circuitry. The device exits Standby mode upon external reset event (NRST pin), IWDG
reset event, wakeup event (WKUP pin, configurable rising or falling edge) or RTC
event (alarm, periodic wakeup, timestamp, tamper), or when a failure is detected on
LSE (CSS on LSE).
•
Shutdown mode: The Shutdown mode allows to achieve the lowest power
consumption. The internal regulator is switched off to power down the VCORE domain.
The PLL, as well as the HSI16 and LSI RC-oscillators and HSE crystal oscillator are
also powered down. The RTC can remain active (Shutdown mode with RTC, Shutdown
mode without RTC). The BOR is not available in Shutdown mode. No power voltage
monitoring is possible in this mode. Therefore, switching to RTC domain is not
supported. SRAM and register contents are lost except for registers in the RTC
domain. The device exits Shutdown mode upon external reset event (NRST pin),
IWDG reset event, wakeup event (WKUP pin, configurable rising or falling edge) or
RTC event (alarm, periodic wakeup, timestamp, tamper).
3.11.5
Reset mode
In order to improve the consumption under reset, the I/Os state under and after reset is
“analog state” (the I/O schmitt trigger is disabled). In addition, the internal reset pull-up is
deactivated when the reset source is internal.

Clocks and startup
The clock controller distributes the clocks coming from different oscillators to the core and
the peripherals. It also manages clock gating for low-power modes and ensures clock
robustness. It features:
•
Clock prescaler: to get the best trade-off between speed and current consumption,
the clock frequency to the CPU and peripherals can be adjusted by a programmable
prescaler
•
•
•
Safe clock switching: clock sources can be changed safely on the fly in run mode
through a configuration register.
Clock management: to reduce power consumption, the clock controller can stop the
clock to the core, individual peripherals or memory.
System clock source: three different sources can deliver SYSCLK system clock:
–
4 - 48 MHz high-speed oscillator with external crystal or ceramic resonator (HSE).
It can supply clock to system PLL. The HSE can also be configured in bypass
mode for an external clock.
–
–
16 MHz high-speed internal RC oscillator (HSI16), trimmable by software. It can
supply clock to system PLL.
System PLL with maximum output frequency of 170 MHz. It can be fed with HSE
or HSI16 clocks.
•
Auxiliary clock source: two ultra-low-power clock sources for the real-time clock
(RTC):
–
32.768 kHz low-speed oscillator with external crystal (LSE), supporting four drive
capability modes. The LSE can also be configured in bypass mode for using an
external clock.
–
32 kHz low-speed internal RC oscillator (LSI) with ±5% accuracy, also used to
clock an independent watchdog.
•
•
Peripheral clock sources: several peripherals (I2S, USART, I2C, LPTimer, ADC, SAI,
RNG) have their own clock independent of the system clock.
Clock security system (CSS): in the event of HSE clock failure, the system clock is
automatically switched to HSI16 and, if enabled, a software interrupt is generated. LSE
clock failure can also be detected and generate an interrupt.
•
Clock-out capability:
–
MCO: microcontroller clock output: it outputs one of the internal clocks for external
use by the application
–
LSCO: low speed clock output: it outputs LSI or LSE in all low-power modes.
Several prescalers allow to configure the AHB frequency, the High-speed APB (APB2) and
the low speed APB (APB1) domains. The maximum frequency of the AHB and the APB
domains is 170 MHz.

General-purpose inputs/outputs (GPIOs)
Each of the GPIO pins can be configured by software as output (push-pull or open-drain), as
input (with or without pull-up or pull-down) or as peripheral alternate function. Most of the
GPIO pins are shared with digital or analog alternate functions. Fast I/O toggling can be
achieved thanks to their mapping on the AHB2 bus.
The I/Os alternate function configuration can be locked if needed following a specific
sequence in order to avoid spurious writing to the I/Os registers.
3.15
Direct memory access controller (DMA)
The device embeds 2 DMAs. Refer to Table 4: DMA implementation for the features
implementation.
Direct memory access (DMA) is used in order to provide a high-speed data transfer
between peripherals and memory as well as from memory to memory. Data can be quickly
moved by DMA without any CPU actions. This keeps the CPU resources free for other
operations.
The two DMA controllers have 16 channels in total, each one dedicated to manage memory
access requests from one or more peripherals. Each controller has an arbiter for handling
the priority between DMA requests.
The DMA supports:
•
16 independently configurable channels (requests)
–
Each channel is connected to a dedicated hardware DMA request, a software
trigger is also supported on each channel. This configuration is done by software.
•
•
Priorities between requests from channels of one DMA are both software
programmable (4 levels: very high, high, medium, low) or hardware programmable in
case of equality (request 1 has priority over request 2, etc.)
Independent source and destination transfer size (byte, half word, word), emulating
packing and unpacking. Source/destination addresses must be aligned on the data
size.
•
•
Support for circular buffer management
3 event flags (DMA half transfer, DMA transfer complete and DMA transfer error)
logically ORed together in a single interrupt request for each channel
•
•
•
•
Memory-to-memory transfer
Peripheral-to-memory, memory-to-peripheral, and peripheral-to-peripheral transfers

DMA request router (DMAMux)
When a peripheral indicates a request for DMA transfer by setting its DMA request line, the
DMA request is pending until it is served and the corresponding DMA request line is reset.
The DMA request router allows to route the DMA control lines between the peripherals and
the DMA controllers of the product.
An embedded multi-channel DMA request generator can be considered as one of such
peripherals. The routing function is ensured by a multi-channel DMA request line
multiplexer. Each channel selects a unique set of DMA control lines, unconditionally or
synchronously with events on synchronization inputs.
For simplicity, the functional description is limited to DMA request lines. The other DMA
control lines are not shown in figures or described in the text. The DMA request generator
produces DMA requests following events on DMA request trigger inputs.

Interrupts and events
3.17.1
Nested vectored interrupt controller (NVIC)
The STM32G473xB/xC/xE devices embed a nested vectored interrupt controller which is
able to manage 16 priority levels, and to handle up to 102 maskable interrupt channels plus
®
the 16 interrupt lines of the Cortex -M4.
The NVIC benefits are the following:
•
•
•
•
•
•
•
Closely coupled NVIC gives low latency interrupt processing
Interrupt entry vector table address passed directly to the core
Allows early processing of interrupts
Processing of late arriving higher priority interrupts
Support for tail chaining
Processor state automatically saved
Interrupt entry restored on interrupt exit with no instruction overhead
The NVIC hardware block provides flexible interrupt management features with minimal
interrupt latency.
3.17.2
Extended interrupt/event controller (EXTI)
The extended interrupt/event controller consists of 44 edge detector lines used to generate
interrupt/event requests and to wake-up the system from the Stop mode. Each external line
can be independently configured to select the trigger event (rising edge, falling edge, both)
and can be masked independently.
A pending register maintains the status of the interrupt requests. The internal lines are
connected to peripherals with wakeup from Stop mode capability. The EXTI can detect an
external line with a pulse width shorter than the internal clock period. Up to 107 GPIOs can
be connected to the 16 external interrupt lines.

Temperature sensor
The temperature sensor (TS) generates a voltage V that varies linearly with temperature.
TS
The temperature sensor is internally connected to the ADCs input channels which is used to
convert the sensor output voltage into a digital value.
The sensor provides good linearity but it has to be calibrated to obtain good overall
accuracy of the temperature measurement. As the offset of the temperature sensor varies
from chip to chip due to process variation, the uncalibrated internal temperature sensor is
suitable for applications that detect temperature changes only.
To improve the accuracy of the temperature sensor measurement, each device is
individually factory-calibrated by ST. The temperature sensor factory calibration data are
stored by ST in the system memory area, accessible in read-only mode.

Advanced motor control timer (TIM1, TIM8, TIM20)
The advanced motor control timers can each be seen as a four-phase
PWM multiplexed on 8 channels. They have complementary PWM outputs with
programmable inserted dead-times. They can also be seen as complete general-purpose
timers.
The 4 independent channels can be used for:
•

•
Input capture
Output compare
PWM generation (edge or center-aligned modes) with full modulation capability
(0-100%)
•
One-pulse mode output
In debug mode, the advanced motor control timer counter can be frozen and the PWM
outputs disabled in order to turn off any power switches driven by these outputs.
Many features are shared with the general-purpose TIMx timers (described in
Section 3.24.2) using the same architecture, so the advanced motor control timers can work
together with the TIMx timers via the Timer Link feature for synchronization or event
chaining.

Universal synchronous/asynchronous receiver transmitter
(USART)
The STM32G473xB/xC/xE devices have three embedded universal synchronous receiver
transmitters (USART1, USART2 and USART3) and two universal asynchronous receiver
transmitters (UART4, USART5).
These interfaces provide asynchronous communication, IrDA SIR ENDEC support,
multiprocessor communication mode, single-wire half-duplex communication mode and
have LIN master/slave capability. They provide hardware management of the CTS and RTS
signals, and RS485 driver enable.
The USART1, USART2 and USART3 also provide a Smartcard mode (ISO 7816 compliant)
and an SPI-like communication capability.
The USART comes with a Transmit FIFO (TXFIFO) and a Receive FIFO (RXFIFO). FIFO
mode is enabled by software and is disabled by default.
All USART have a clock domain independent from the CPU clock, allowing the U(S)ARTx
(x=1,2,3,4,5) to wake up the MCU from Stop mode. The wakeup from Stop mode can be
done on:
•
•
•

Low-power universal asynchronous receiver transmitter
(LPUART)
The STM32G473xB/xC/xE devices embed one Low-Power UART. The LPUART supports
asynchronous serial communication with minimum power consumption. It supports half-
duplex single-wire communication and modem operations (CTS/RTS). It allows
multiprocessor communication.
The LPUART comes with a Transmit FIFO (TXFIFO) and a Receive FIFO (RXFIFO). FIFO
mode is enabled by software and is disabled by default. It has a clock domain independent
from the CPU clock, and can wakeup the system from Stop mode. The wake up from Stop
mode can be done on:
•
•
•
•
Start bit detection
Any received data frame
A specific programmed data frame
Some specific TXFIFO/RXFIFO status interrupts when FIFO mode is enabled
Only a 32.768 kHz clock (LSE) is needed to allow LPUART communication up to 9600
baud. Therefore, even in Stop mode, the LPUART can wait for an incoming frame while
having an extremely low energy consumption. Higher speed clock can be used to reach
higher baudrates.
The LPUART interface can be served by the DMA controller.
3.31
Serial peripheral interface (SPI)
Four SPI interfaces allow communication up to 75 Mbits/s in master and up to 41 Mbits/s in
slave, half-duplex, full-duplex and simplex modes. The 3-bit prescaler gives 8 master mode
frequencies and the frame size is configurable from 4 bits to 16 bits. The SPI interfaces
support NSS pulse mode, TI mode and hardware CRC calculation.
2
Two standard I S interfaces (multiplexed with SPI2 and SPI3) supporting four different audio
standards can operate as master or slave at half-duplex communication modes. They can
be configured to transfer 16 and 24 or 32 bits with 16-bit or 32-bit data resolution and
synchronized by a specific signal. Audio sampling frequency from 8 kHz up to 192 kHz can
be set by 8-bit programmable linear prescaler. When operating in master mode it can output
a clock for an external audio component at 256 times the sampling frequency.
All SPI interfaces can be served by the DMA controller.

Functional overview
STM32G473xB STM32G473xC STM32G473xE
The digital controller handles notably:
•
•
•
USB Type-C level detection with de-bounce, generating interrupts
FRS detection, generating an interrupt
Byte-level interface for USB Power Delivery payload, generating interrupts (DMA
compatible)
•
•
•
•
•
USB Power Delivery timing dividers (including a clock pre-scaler)
CRC generation/checking
4b5b encode/decode
Ordered sets (with a programmable ordered set mask at receive)
Frequency recovery in receiver during preamble
The interface offers low-power operation compatible with Stop mode, maintaining the
capacity to detect incoming USB Power Delivery messages and FRS signaling.

3.37
Clock recovery system (CRS)
The devices embed a special block which allows automatic trimming of the internal 48 MHz
oscillator to guarantee its optimal accuracy over the whole device operational range. This
automatic trimming is based on the external synchronization signal, which could be either
derived from USB SOF signalization, from LSE oscillator, from an external signal on
CRS_SYNC pin or generated by user software. For faster lock-in during startup it is also
possible to combine automatic trimming with manual trimming action.
Flexible static memory controller (FSMC)
The Flexible static memory controller (FSMC) includes two memory controllers:
•
•
The NOR/PSRAM memory controller
The NAND/memory controller
This memory controller is also named Flexible memory controller (FMC).
The main features of the FMC controller are the following:
•
Interface with static-memory mapped devices including:
–
–
–
–
–
Static random access memory (SRAM)
NOR Flash memory/OneNAND Flash memory
PSRAM (4 memory banks)
NAND Flash memory with ECC hardware to check up to 8 Kbytes of data
Ferroelectric RAM (FRAM)
•
•
•
•
•
8-,16- bit data bus width
Independent Chip Select control for each memory bank
Independent configuration for each memory bank
Write FIFO
The Maximum FMC_CLK frequency for synchronous accesses is HCLK/2.

LCD parallel interface
Functional overview
The FMC can be configured to interface seamlessly with most graphic LCD controllers. It
supports the Intel 8080 and Motorola 6800 modes, and is flexible enough to adapt to
specific LCD interfaces. This LCD parallel interface capability makes it easy to build cost
effective graphic applications using LCD modules with embedded controllers or high
performance solutions using external controllers with dedicated acceleration.
3.38
Quad SPI memory interface (QUADSPI)
The Quad SPI is a specialized communication interface targeting single, dual or quad SPI
flash memories. It can operate in any of the three following modes:
•
•
Indirect mode: all the operations are performed using the QUADSPI registers
Status polling mode: the external flash status register is periodically read and an
interrupt can be generated in case of flag setting
•
Memory-mapped mode: the external Flash is memory mapped and is seen by the
system as if it were an internal memory.
Both throughput and capacity can be increased two-fold using dual-flash mode, where two
quad SPI flash memories are accessed simultaneously.
The Quad SPI interface supports:
•
•
Indirect mode: all the operations are performed using the QUADSPI registers
Status polling mode: the external flash status register is periodically read and an
interrupt can be generated in case of flag setting
•
Memory-mapped mode: the external Flash is memory mapped and is seen by the
system as if it were an internal memory
•
•
•
•
Three functional modes: indirect, status-polling, and memory-mapped
SDR and DDR support
Fully programmable opcode for both indirect and memory mapped mode
Fully programmable frame format for both indirect and memory mapped mode
–
Each of the 5 following phases can be configured independently (enable, length,
single/dual/quad communication)
–
–
–
–
–
Instruction phase
Address phase
Alternate bytes phase
Dummy cycles phase
Data phase
•
•
•
•
•
•
Integrated FIFO for reception and transmission
8, 16, and 32-bit data accesses are allowed
DMA channel for indirect mode operations
Programmable masking for external flash flag management
Timeout management
Interrupt generation on FIFO threshold, timeout, status match, operation complete, and
access error

Development support
3.39.1
Serial wire JTAG debug port (SWJ-DP)
The Arm SWJ-DP interface is embedded, and is a combined JTAG and serial wire debug
port that enables either a serial wire debug or a JTAG probe to be connected to the target.
Debug is performed using 2 pins only instead of 5 required by the JTAG (JTAG pins could
be re-use as GPIO with alternate function): the JTAG TMS and TCK pins are shared with
SWDIO and SWCLK, respectively, and a specific sequence on the TMS pin is used to
switch between JTAG-DP and SW-DP.
3.39.2
Embedded trace macrocell™
The Arm embedded trace macrocell provides a greater visibility of the instruction and data
flow inside the CPU core by streaming compressed data at a very high rate from the
STM32G473xB/xC/xE devices through a small number of ETM pins to an external hardware
trace port analyzer (TPA) device. Real-time instruction and data flow activity be recorded
and then formatted for display on the host computer that runs the debugger software. TPA
hardware is commercially available from common development tool vendors.
The Embedded trace macrocell operates with third party debugger software tools.

1. Function availability depends on the chosen device.
2. PC13, PC14 and PC15 are supplied through the power switch. Since the switch only sinks a limited amount of current (3
mA), the use of GPIOs PC13 to PC15 in output mode is limited:
- The speed should not exceed 2 MHz with a maximum load of 30 pF
- These GPIOs must not be used as current sources (e.g. to drive an LED).
3. After a backup domain power-up, PC13, PC14 and PC15 operate as GPIOs. Their function then depends on the content of
the RTC registers which are not reset by the system reset. For details on how to manage these GPIOs, refer to the Backup
domain and RTC register descriptions in the reference manual RM0440 "STM32G4 Series advanced Arm®-based 32-bit
MCUs".
4. After reset, these pins are configured as JTAG/SW debug alternate functions, and the internal pull-up on PA15, PA13, PB4
pins and the internal pull-down on PA14 pin are activated.
5. After reset, a pull-down resistor (Rd = 5.1kΩ from UCPD peripheral) can be activated on PB6, PB4 (UCPD1_CC1,
UCPD1_CC2). The pull-down on PB6 (UCPD1_CC1) is activated by high level on PA9 (UCPD1_DBCC1). The pull-down on
PB4 (UCPD1_CC2) is activated by high level on PA10 (UCPD1_DBCC2). This pull-down control (dead battery support on
UCPD peripheral) can be disabled by setting bit UCPD1_DBDIS=1 in the PWR_CR3 register. PB4, PB6 have UCPD_CC
functionality which implements an internal pull-down resistor (5.1kΩ) which is controlled by the voltage on the
UCPD_DBCC pin (PA10, PA9). A high level on the UCPD_DBCC pin activates the pull-down on the UCPD_CC pin. The
pull-down effect on the CC lines can be removed by using the bit UCPD1_DBDIS =1 (USB Type-C and power delivery dead
battery disable) in the PWR_CR3 register.
6. It is recommended to set PB8 in another mode than analog mode after startup to limit consumption if the pin is left
unconnected.

Supply current characteristics
The current consumption is a function of several parameters and factors such as the
operating voltage, ambient temperature, I/O pin loading, device software configuration,
operating frequencies, I/O pin switching rate, program location in memory and executed
binary code
The current consumption is measured as described in Figure 17: Current consumption
measurement.
Typical and maximum current consumption
The MCU is placed under the following conditions:
•
•
•
All I/O pins are in analog input mode
All peripherals are disabled except when explicitly mentioned
The Flash memory access time is adjusted with the minimum wait states number,
depending on the f
frequency (refer to the table “number of wait states according
HCLK
to CPU clock (HCLK) frequency” available in the reference manual RM0440
®
"STM32G4 Series advanced Arm -based 32-bit MCUs").
•
•
When the peripherals are enabled f
= f

The voltage scaling Range 1 is adjusted to f
frequency as follows:

Electrical characteristics
STM32G473xB STM32G473xC STM32G473xE
IO system current consumption
The current consumption of the I/O system has two components: static and dynamic.
I/O static current consumption
All the I/Os used as inputs with pull-up generate current consumption when the pin is
externally held low. The value of this current consumption can be simply computed by using
the pull-up/pull-down resistors values given in Table 54: I/O static characteristics.
For the output pins, any external pull-down or external load must also be considered to
estimate the current consumption.
Additional I/O current consumption is due to I/Os configured as inputs if an intermediate
voltage level is externally applied. This current consumption is caused by the input Schmitt
trigger circuits used to discriminate the input value. Unless this specific configuration is
required by the application, this supply current consumption can be avoided by configuring
these I/Os in analog mode. This is notably the case of ADC, OPAMP, COMP input pins
which should be configured as analog inputs.
Caution:
Any floating input pin can also settle to an intermediate voltage level or switch inadvertently,
as a result of external electromagnetic noise. To avoid current consumption related to
floating pins, they must either be configured in analog mode, or forced internally to a definite
digital value. This is done either by using pull-up/down resistors or by configuring the pins in
output mode.
I/O dynamic current consumption
In addition to the internal peripheral current consumption measured previously (see
Table 36: Low-power mode wakeup timings), the I/Os used by an application also contribute
to the current consumption. When an I/O pin switches, it uses the current from the I/O
supply voltage to supply the I/O pin circuitry and to charge/discharge the capacitive load
(internal or external) connected to the pin:
ISW = VDDIOx × fSW × C
where
I
is the current sunk by a switching I/O to charge/discharge the capacitive load
is the I/O supply voltage
SW
V
DD
f
is the I/O switching frequency
SW
C is the total capacitance seen by the I/O pin: C = C + C
C
S
INT
EXT +
C is the PCB board capacitance including the pad pin.
S
The test pin is configured in push-pull output mode and is toggled by software at a fixed
frequency.

On-chip peripheral current consumption
The current consumption of the on-chip peripherals is given in Table 35. The MCU is placed
under the following conditions:
•
•
All I/O pins are in Analog mode
The given value is calculated by measuring the difference of the current consumptions:

High-speed external clock generated from a crystal/ceramic resonator
The high-speed external (HSE) clock can be supplied with a 4 to 48 MHz crystal/ceramic
resonator oscillator. All the information given in this paragraph are based on design
simulation results obtained with typical external components specified in Table 41. In the
application, the resonator and the load capacitors have to be placed as close as possible to
the oscillator pins in order to minimize output distortion and startup stabilization time. Refer
to the crystal resonator manufacturer for more details on the resonator characteristics
(frequency, package, accuracy).

EMC characteristics
Susceptibility tests are performed on a sample basis during device characterization.
Functional EMS (electromagnetic susceptibility)
While a simple application is executed on the device (toggling 2 LEDs through I/O ports).
the device is stressed by two electromagnetic events until a failure occurs. The failure is
indicated by the LEDs:
•
Electrostatic discharge (ESD) (positive and negative) is applied to all device pins until
a functional disturbance occurs. This test is compliant with the IEC 61000-4-2 standard.
•
FTB: A Burst of Fast Transient voltage (positive and negative) is applied to V and
DD
V
through a 100 pF capacitor, until a functional disturbance occurs. This test is
SS
compliant with the IEC 61000-4-4 standard.
A device reset allows normal operations to be resumed.
The test results are given in Table 49. They are based on the EMS levels and classes
defined in application note AN1709.

Designing hardened software to avoid noise problems
EMC characterization and optimization are performed at component level with a typical
application environment and simplified MCU software. It should be noted that good EMC
performance is highly dependent on the user application and the software in particular.
Therefore it is recommended that the user applies EMC software optimization and
prequalification tests in relation with the EMC level requested for his application.
Software recommendations
The software flowchart must include the management of runaway conditions such as:
•
•
•
Corrupted program counter
Unexpected reset
Critical Data corruption (control registers...)
Prequalification trials
Most of the common failures (unexpected reset and program counter corruption) can be
reproduced by manually forcing a low state on the NRST pin or the Oscillator pins for 1
second.
DS12712 Rev 3
123/229
194
Electrical characteristics
STM32G473xB STM32G473xC STM32G473xE
To complete these trials, ESD stress can be applied directly on the device, over the range of
specification values. When unexpected behavior is detected, the software can be hardened
to prevent unrecoverable errors occurring (see application note AN1015).
Electromagnetic Interference (EMI)
The electromagnetic field emitted by the device are monitored while a simple application is
executed (toggling 2 LEDs through the I/O ports). This emission test is compliant with
IEC 61967-2 standard which specifies the test board and the pin loading.

Electrical sensitivity characteristics
Based on three different tests (ESD, LU) using specific measurement methods, the device is
stressed in order to determine its performance in terms of electrical sensitivity.
Electrostatic discharge (ESD)
Electrostatic discharges (a positive then a negative pulse separated by 1 second) are
applied to the pins of each sample according to each pin combination. The sample size
depends on the number of supply pins in the device (3 parts × (n+1) supply pins). This test
conforms to the ANSI/JEDEC standard.

Two complementary static tests are required on three parts to assess the latch-up
performance:
•
•

I/O current injection characteristics
As a general rule, current injection to the I/O pins, due to external voltage below V or
SS
above V (for standard, 3.3 V-capable I/O pins) should be avoided during normal product
DD
operation. However, in order to give an indication of the robustness of the microcontroller in
cases when abnormal injection accidentally happens, susceptibility tests are performed on a
sample basis during device characterization.
Functional susceptibility to I/O current injection
While a simple application is executed on the device, the device is stressed by injecting
current into the I/O pins programmed in floating input mode. While current is injected into
the I/O pin, one at a time, the device is checked for functional failures.
The failure is indicated by an out of range parameter: ADC error above a certain limit (higher
than 5 LSB TUE), out of conventional limits of induced leakage current on adjacent pins (out
of the -5 µA/+0 µA range) or other functional failure (for example reset occurrence or
oscillator frequency deviation).
The characterization results are given in Table 53.
Negative induced leakage current is caused by negative injection and positive induced
leakage current is caused by positive injection.

4. This value represents the pad leakage of the I/O itself. The total product pad leakage is provided by this formula:
ITotal_Ileak_max = 10 μA + [number of I/Os where VIN is applied on the pad] ₓ Ilkg(Max).
5. Pull-up and pull-down resistors are designed with a true resistance in series with a switchable PMOS/NMOS. This
PMOS/NMOS contribution to the series resistance is minimal (~10% order).
Note:
For more information about GPIO properties, refer to the application note AN4899 "STM32
GPIO configuration for hardware settings and low-power consumption" available from the
ST website www.st.com.
All I/Os are CMOS- and TTL-compliant (no software configuration required). Their
characteristics cover more than the strict CMOS-technology or TTL parameters. The
coverage of these requirements is shown in Figure 25 for standard I/Os, and in Figure 25 for
5 V tolerant I/Os.

1. Refer to Table 61: ADC characteristics for the values of RAIN and CADC
.
2. Cparasitic represents the capacitance of the PCB (dependent on soldering and PCB layout quality) plus the
pad capacitance (refer to Table 54: I/O static characteristics for the value of the pad capacitance). A high
C
parasitic value downgrades conversion accuracy. To remedy this, fADC should be reduced.
3. Refer to Table 54: I/O static characteristics for the values of Ilkg
.

1. Guaranteed by design, unless otherwise specified.
2. In degraded mode, the voltage reference buffer can not maintain accurately the output voltage which follows (VDDA - drop
voltage).
3. Guaranteed by characterization results.
4. Line regulation is given for overall supply variation, in normal mode.
5. Tcoeff_vrefint refer to Tcoeff parameter in the embedded voltage reference section.
6. The capacitive load must include a 100 nF low ESR capacitor in order to cut-off the high frequency noise.
7. To correctly control the VREFBUF inrush current during start-up phase and scaling change, the VDDA voltage should be in
the range [2.4 V to 3.6 V], [2.8 V to 3.6 V] and [3.135 V to 3.6 V] respectively for VRS=0,1 and 2.

The I2C interface meets the timings requirements of the I C-bus specification and user
manual rev. 03 for:
•
•
•
Standard-mode (Sm): with a bit rate up to 100 kbit/s
Fast-mode (Fm): with a bit rate up to 400 kbit/s
Fast-mode Plus (Fm+): with a bit rate up to 1 Mbit/s.
The I2C timings requirements are guaranteed by design when the I2C peripheral is properly
®
configured (refer to reference manual RM0440 "STM32G4 Series advanced Arm -based
32-bit MCUs") and when the I2CCLK frequency is greater than the minimum shown in the

The SDA and SCL I/O requirements are met with the following restrictions:
•
The SDA and SCL I/O pins are not “true” open-drain. When configured as open-drain,
the PMOS connected between the I/O pin and V is disabled, but is still present.
DDIOx
•
The 20mA output drive requirement in Fast-mode Plus is supported partially. This limits
the maximum load Cload supported in Fm+, which is given by these formulas:
–

Where Rp is the I2C lines pull-up. Refer to Section 5.3.14: I/O port characteristics for the

6.10.2
Selecting the product temperature range
When ordering the microcontroller, the temperature range is specified in the ordering
information scheme shown in Section 7: Ordering information.
Each temperature range suffix corresponds to a specific guaranteed ambient temperature at
maximum dissipation and, to a specific maximum junction temperature.
As applications do not commonly use the STM32G473xE at maximum dissipation, it is
useful to calculate the exact power consumption and junction temperature to determine
which temperature range is best suited to the application.
The following examples show how to calculate the temperature range needed for a given
application.
Example 1: High-performance application
Assuming the following application conditions:
Maximum ambient temperature T
= 82 °C (measured according to JESD51-2),
Amax
I
= 50 mA, V = 3.5 V, maximum 20 I/Os used at the same time in output at low
DDmax
DD
level with I = 8 mA, V = 0.4 V and maximum 8 I/Os used at the same time in output
OL
OL
at low level with I = 20 mA, V = 1.3 V
OL
OL
P
P
50 mA × 3.5 V= 175 mW
INTmax =
20 × 8 mA × 0.4 V + 8 × 20 mA × 1.3 V = 272 mW
IOmax =
This gives: P
= 175 mW and P
= 272 mW:
IOmax
INTmax
P
175 272 = 447 mW
+
Dmax =
Using the values obtained in T
is calculated as follows:
Jmax
–
T
For LQFP100, 42 °C/W
= 82 °C + (42 °C/W × 447 mW) = 82 °C + 18.774 °C = 100.774 °C
Jmax
This is within the range of the suffix 6 version parts (–40 < T < 105 °C) see Section 7:
J
Ordering information.
In this case, parts must be ordered at least with the temperature range suffix 6 (see
Section 7: Ordering information).
Note:
With this given P
we can find the TAmax allowed for a given device temperature range
Dmax
(order code suffix 6 or 7).
Suffix 6: T
Suffix 3: T
= T
= T
- (42°C/W × 447 mW) = 105-18.774 = 86.226 °C
Amax
Amax
Jmax
Jmax
- (42°C/W × 447 mW) = 130-18.774 = 111.226 °C
Example 2: High-temperature application
Using the same rules, it is possible to address applications that run at high ambient
temperatures with a low dissipation, as long as junction temperature T remains within the
J
specified range.

STM32G473xB STM32G473xC STM32G473xE
Package information
Assuming the following application conditions:
Maximum ambient temperature T
= 100 °C (measured according to JESD51-2),
Amax
I
= 20 mA, V = 3.5 V, maximum 20 I/Os used at the same time in output at low
DDmax
DD
level with I = 8 mA, V = 0.4 V
OL
OL
P
P
20 mA × 3.5 V= 70 mW
INTmax =
× 8 mA × 0.4 V = 64 mW
IOmax = 20
This gives: P
= 70 mW and P
= 64 mW:
IOmax
INTmax
P
70 64 = 134 mW
Dmax =
+
Thus: P
= 134 mW
Dmax
Using the values obtained in T
is calculated as follows:
Jmax
–
T
For LQFP100, 42 °C/W
= 100 °C + (42 °C/W × 134 mW) = 100 °C + 5.628 °C = 105.628 °C
Jmax
This is above the range of the suffix 6 version parts (–40 < T < 105 °C).
J
In this case, parts must be ordered at least with the temperature range suffix 3 (see
Section 7: Ordering information) unless we reduce the power dissipation in order to be able
to use suffix 6 parts.
