STM32F722xx STM32F723xx
Description
The STM32F722xx and STM32F723xx devices are based on the high-performance Arm®
Cortex®-M7 32-bit RISC core operating at up to 216 MHz frequency. The Cortex®-M7 core
features a single floating point unit (SFPU) precision which supports Arm® single-precision
data-processing instructions and data types. It also implements a full set of DSP instructions
and a memory protection unit (MPU) which enhances the application security.
The STM32F722xx and STM32F723xx devices incorporate high-speed embedded
memories with a Flash memory up to 512 Kbytes, 256 Kbytes of SRAM (including
64 Kbytes of data TCM RAM for critical real-time data), 16 Kbytes of instruction TCM RAM
(for critical real-time routines), 4 Kbytes of backup SRAM available in the lowest power
modes, and an extensive range of enhanced I/Os and peripherals connected to two APB
buses, two AHB buses, a 32-bit multi-AHB bus matrix and a multi layer AXI interconnect
supporting internal and external memories access.
All the devices offer three 12-bit ADCs, two DACs, a low-power RTC, thirteen generalpurpose 16-bit timers including two PWM timers for motor control, two general-purpose 32bit timers, a true random number generator (RNG). They also feature standard and
advanced communication interfaces.

Up to three I2Cs
Five SPIs, three I2Ss in half duplex mode. To achieve the audio class accuracy, the I2S
peripherals can be clocked via a dedicated internal audio PLL or via an external clock
to allow synchronization.
Four USARTs plus four UARTs
An USB OTG full-speed and a USB OTG high-speed with full-speed capability (with the
ULPI or with the integrated HS PHY depending on the part number)
One CAN
Two SAI serial audio interfaces
Two SDMMC host interfaces
Advanced peripherals include two SDMMC interfaces, a flexible memory control (FMC)
interface, a Quad-SPI Flash memory interface.
The STM32F722xx and STM32F723xx devices operate in the –40 to +105 °C temperature
range from a 1.7 to 3.6 V power supply. Dedicated supply inputs for the USB (OTG_FS and
OTG_HS) and the SDMMC2 (clock, command and 4-bit data) are available on all the
packages except LQFP100 and LQFP64 for a greater power supply choice.
The supply voltage can drop to 1.7 V with the use of an external power supply supervisor. A
comprehensive set of power-saving mode allows the design of low-power applications.
The STM32F722xx and STM32F723xx devices offer devices in 7 packages ranging from 64
pins to 176 pins. The set of included peripherals changes with the device chosen.

3.1
Arm® Cortex®-M7 with FPU
The Arm® Cortex®-M7 with FPU processor is the latest generation of Arm processors for
embedded systems. It was developed to provide a low-cost platform that meets the needs of
MCU implementation, with a reduced pin count and low-power consumption, while
delivering outstanding computational performance and low interrupt latency.
The Cortex®-M7 processor is a highly efficient high-performance featuring:
–
Six-stage dual-issue pipeline
–
Dynamic branch prediction
–
Harvard caches (8 Kbytes of I-cache and 8 Kbytes of D-cache)
–
64-bit AXI4 interface
–
64-bit ITCM interface
–
2x32-bit DTCM interfaces
The processor supports the following memory interfaces:
•
Tightly Coupled Memory (TCM) interface.
•
Harvard instruction and data caches and AXI master (AXIM) interface.
•
Dedicated low-latency AHB-Lite peripheral (AHBP) interface.
The processor supports a set of DSP instructions which allow efficient signal processing and
complex algorithm execution.
It supports single precision FPU (floating point unit), speeds up software development by
using metalanguage development tools, while avoiding saturation.
Figure 6 shows the general block diagram of the STM32F722xx and STM32F723xx family.
Note:
Cortex®-M7 with FPU core is binary compatible with the Cortex®-M4 core.
3.2
Memory protection unit
The memory protection unit (MPU) is used to manage the CPU accesses to memory to
prevent one task to accidentally corrupt the memory or resources used by any other active
task. This memory area is organized into up to 8 protected areas that can in turn be divided
up into 8 subareas. The protection area sizes are 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 (realtime 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.

Functional overview
Embedded Flash memory
The STM32F722xx and STM32F723xx devices embed a Flash memory of up to 512 Kbytes
available for storing programs and data.
The flexible protections can be configured thanks to option bytes:
•
3.4
Readout protection (RDP) to protect the whole memory. Three levels are available:
–
Level 0: no readout protection
–
Level 1: No access (read, erase, program) to the Flash memory or backup SRAM
can be performed while the debug feature is connected or while booting from RAM
or system memory bootloader
–
Level 2: debug/chip read protection disabled.
•
Write protection (WRP): the protected area is protected against erasing and
programming.
•
Proprietary code readout protection (PCROP): Flash memory user sectors (0 to 7) can
be protected against D-bus read accesses by using the proprietary readout protection
(PCROP). The protected area is execute-only.
CRC (cyclic redundancy check) calculation unit
The CRC (cyclic redundancy check) calculation unit is used to get a CRC code using a
configurable generator polynomial value and size.
Among other applications, 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 means of
verifying the Flash memory integrity. The CRC calculation unit helps compute a signature of
the software during runtime, to be compared with a reference signature generated at linktime and stored at a given memory location.
3.5
Embedded SRAM
All the devices feature:
•
•
System SRAM up to 256 Kbytes:
–
SRAM1 on AHB bus Matrix: 176 Kbytes
–
SRAM2 on AHB bus Matrix: 16 Kbytes
–
DTCM-RAM on TCM interface (Tighly Coupled Memory interface): 64 Kbytes for
critical real-time data.
Instruction RAM (ITCM-RAM) 16 Kbytes:
–
It is mapped on TCM interface and reserved only for CPU Execution/Instruction
useful for critical real-time routines.
The Data TCM RAM is accessible by the GP-DMAs and peripheral DMAs through the
specific AHB slave of the CPU.The instruction TCM RAM is reserved only for CPU. It is
accessed at CPU clock speed with 0 wait states.
•
4 Kbytes of backup SRAM
This area is accessible only from the CPU. Its content is protected against possible
unwanted write accesses, and is retained in Standby or VBAT mode.

AXI-AHB bus matrix
The STM32F722xx and STM32F723xx system architecture is based on 2 sub-systems:
•
•
An AXI to multi AHB bridge converting AXI4 protocol to AHB-Lite protocol:
–
3x AXI to 32-bit AHB bridges connected to AHB bus matrix
–
1x AXI to 64-bit AHB bridge connected to the embedded Flash memory
A multi-AHB Bus-Matrix
–
The 32-bit multi-AHB bus matrix interconnects all the masters (CPU, DMAs, USB
HS) and the slaves (Flash memory, RAM, FMC, Quad-SPI, AHB and APB
peripherals) and ensures a seamless and efficient operation even when several
high-speed peripherals work simultaneously.

Functional overview
DMA controller (DMA)
The devices feature two general-purpose dual-port DMAs (DMA1 and DMA2) with 8
streams each. They are able to manage memory-to-memory, peripheral-to-memory and
memory-to-peripheral transfers. They feature dedicated FIFOs for APB/AHB peripherals,
support burst transfer and are designed to provide the maximum peripheral bandwidth
(AHB/APB).
The two DMA controllers support a circular buffer management, so that no specific code is
needed when the controller reaches the end of the buffer. The two DMA controllers also
have a double buffering feature, which automates the use and switching of two memory
buffers without requiring any special code.
Each stream is connected to dedicated hardware DMA requests, with support for software
trigger on each stream. The configuration is made by software and transfer sizes between
source and destination are independent.
The DMA can be used with the main peripherals:
•
SPI and I2S
•
I2C
•
USART
•
General-purpose, basic and advanced-control timers TIMx
•
DAC
•
SDMMC

Flexible memory controller (FMC)
The Flexible memory controller (FMC) includes three memory controllers:
•
The NOR/PSRAM memory controller
•
The NAND/memory controller
•
The Synchronous DRAM (SDRAM/Mobile LPSDR SDRAM) controller
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
•
Interface with synchronous DRAM (SDRAM/Mobile LPSDR SDRAM) memories
•
8-, 16-, 32-bit data bus width
•
Independent Chip Select control for each memory bank
•
Independent configuration for each memory bank
•
Write FIFO
•
Read FIFO for SDRAM controller
•
The maximum FMC_CLK/FMC_SDCLK frequency for synchronous accesses is
HCLK/2
LCD parallel interface
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 costeffective graphic applications using LCD modules with embedded controllers or high
performance solutions using external controllers with dedicated acceleration.
3.9
Quad-SPI memory interface (QUADSPI)
All the devices embed a Quad-SPI memory interface, which is a specialized communication
interface targetting Single, Dual or Quad-SPI Flash memories. It can work in:
•
Direct mode through registers
•
External Flash status register polling mode
•
Memory mapped mode.
Up to 256 Mbytes of external Flash are memory mapped, supporting 8, 16 and 32-bit
access. The code execution is supported.
The opcode and the frame format are fully programmable. The communication can be either
in Single Data Rate or Dual Data Rate.

Nested vectored interrupt controller (NVIC)
The devices embed a nested vectored interrupt controller able to manage 16 priority levels,
and handle up to 110 maskable interrupt channels plus the 16 interrupt lines of the Cortex®M7 with FPU core.
•
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 tail chaining
•
Processor state automatically saved
•
Interrupt entry restored on interrupt exit with no instruction overhead
This hardware block provides flexible interrupt management features with a minimum
interrupt latency.
3.11
External interrupt/event controller (EXTI)
The external interrupt/event controller consists of 24 edge-detector lines used to generate
interrupt/event requests. Each 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 EXTI can detect an external line with a
pulse width shorter than the Internal APB2 clock period. Up to 140 GPIOs in the
STM32F722xx devices (138 GPIOs in the STM32F723xx devices) can be connected to the
16 external interrupt lines.
3.12
Clocks and startup
On reset the 16 MHz internal HSI RC oscillator is selected as the default CPU clock. The
16 MHz internal RC oscillator is factory-trimmed to offer 1% accuracy. The application can
then select as system clock either the RC oscillator or an external 4-26 MHz clock source.
This clock can be monitored for failure. If a failure is detected, the system automatically
switches back to the internal RC oscillator and a software interrupt is generated (if enabled).
This clock source is input to a PLL thus allowing to increase the frequency up to 216 MHz.
Similarly, a full interrupt management of the PLL clock entry is available when necessary
(for example if an indirectly used external oscillator fails).
Several prescalers allow the configuration of the two AHB buses, the high-speed APB
(APB2) and the low-speed APB (APB1) domains. The maximum frequency of the two AHB
buses is 216 MHz while the maximum frequency of the high-speed APB domains is
108 MHz. The maximum allowed frequency of the low-speed APB domain is 54 MHz.
The devices embed two dedicated PLLs (PLLI2S and PLLSAI) which allow to achieve audio
class performance. In this case, the I2S and SAI master clock can generate all standard
sampling frequencies from 8 kHz to 192 kHz.
The STM32F723xx devices embed two PLLs inside the PHY HS controller: PLL1 and PLL2.
The PLL1 allows to output 60 MHz used as an input for PLL2 which itself allows to generate
the 480 Mbps in the USB OTG High Speed mode.
The PLL1 has as input HSE clock.

Boot modes
At startup, the boot memory space is selected by the BOOT pin and BOOT_ADDx option
bytes, allowing to program any boot memory address from 0x0000 0000 to 0x3FFF FFFF
which includes:
•
All Flash address space mapped on ITCM or AXIM interface
•
All RAM address space: ITCM, DTCM RAMs and SRAMs mapped on AXIM interface
•
The System memory bootloader
The boot loader is located in system memory. It is used to reprogram the Flash memory
through a serial interface.

Note:
Power supply schemes
•
VDD = 1.7 to 3.6 V: external power supply for I/Os and the internal regulator (when
enabled), provided externally through VDD pins.
•
VSSA, VDDA = 1.7 to 3.6 V: external analog power supplies for ADC, DAC, Reset
blocks, RCs and PLL. VDDA and VSSA must be connected to VDD and VSS, respectively.
•
VBAT = 1.65 to 3.6 V: power supply for RTC, external clock 32 kHz oscillator and
backup registers (through power switch) when VDD is not present.
The VDD/VDDA minimum value of 1.7 V is obtained when the internal reset is OFF (refer to
Section 3.15.2: Internal reset OFF). Refer to Table 3: Voltage regulator configuration mode
versus device operating mode to identify the packages supporting this option.

The VDDSDMMC can be connected either to VDD or an external independent power
supply (1.8 to 3.6V) for the SDMMC2 pins (clock, command, and 4-bit data). For
example, when the device is powered at 1.8V, an independent power supply 2.7V can
be connected to VDDSDMMC.When the VDDSDMMC is connected to a separated power
supply, it is independent from VDD or VDDA but it must be the last supply to be provided
and the first to disappear. The following conditions VDDSDMMC must be respected:
–
During the power-on phase (VDD < VDD_MIN), VDDSDMMC should be always lower
than VDD
–
During the power-down phase (VDD < VDD_MIN), VDDSDMMC should be always
lower than VDD
–
The VDDSDMMC rising and falling time rate specifications must be respected
–
In the operating mode phase, VDDSDMMC could be lower or higher than VDD:
All associated GPIOs powered by VDDSDMMC are operating between
VDDSDMMC_MIN and VDDSDMMC_MAX.
The VDDUSB can be connected either to VDD or an external independent power supply
(3.0 to 3.6V) for USB transceivers (refer to Figure 8 and Figure 9). For example, when
the device is powered at 1.8V, an independent power supply 3.3V can be connected to
the VDDUSB. When the VDDUSB is connected to a separated power supply, it is
independent from VDD or VDDA but it must be the last supply to be provided and the first
to disappear. The following conditions VDDUSB must be respected:
–
During the power-on phase (VDD < VDD_MIN), VDDUSB should be always lower
than VDD
–
During the power-down phase (VDD < VDD_MIN), VDDUSB should be always lower
than VDD

STM32F722xx STM32F723xx
On the STM32F7x3xx devices, the USB OTG HS sub-system uses one or two additional
power supply pins depending on the package:
•
The VDD12OTGHS pin is the output of PHY HS regulator (1.2V). An external capacitor
of 2.2 µF must be connected on the VDD12OTGHS pin.
•
On the LQFP100 only, a second power pin VDDPHYHS is used to supply the USB
OTG PHY HS and associated GPIOs.The VDDPHYHS follows the same rules provided
for the VDDUSB power pin.
3.15
Power supply supervisor
3.15.1
Internal reset ON
On packages embedding the PDR_ON pin, the power supply supervisor is enabled by
holding PDR_ON high. On the other packages, the power supply supervisor is always
enabled.
The device has an integrated power-on reset (POR)/ power-down reset (PDR) circuitry
coupled with a Brownout reset (BOR) circuitry. At power-on, POR/PDR is always active and
ensures proper operation starting from 1.8 V. After the 1.8 V POR threshold level is
reached, the option byte loading process starts, either to confirm or modify default BOR
thresholds, or to disable BOR permanently. Three BOR thresholds are available through
option bytes. The device remains in reset mode when VDD is below a specified threshold,
VPOR/PDR or VBOR, without the need for an external reset circuit.
The device also features an embedded programmable voltage detector (PVD) that monitors
the VDD/VDDA power supply and compares it to the VPVD threshold. An interrupt can be
generated when VDD/VDDA drops below the VPVD threshold and/or when VDD/VDDA is
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.
3.15.2
Internal reset OFF
This feature is available only on packages featuring the PDR_ON pin. The internal power-on
reset (POR) / power-down reset (PDR) circuitry is disabled through the PDR_ON pin.
An external power supply supervisor should monitor VDD and NRST and should maintain
the device in reset mode as long as VDD is below a specified threshold. PDR_ON should be
connected to VSS. Refer to Figure 10: Power supply supervisor interconnection with internal
reset OFF.

•
The integrated power-on reset (POR) / power-down reset (PDR) circuitry is disabled
•
The brownout reset (BOR) circuitry must be disabled
•
The embedded programmable voltage detector (PVD) is disabled
•
VBAT functionality is no more available and VBAT pin should be connected to VDD.

STM32F722xx STM32F723xx
Voltage regulator
The regulator has four operating modes:
•
•
3.16.1
Regulator ON
–
Main regulator mode (MR)
–
Low power regulator (LPR)
–
Power-down
Regulator OFF
Regulator ON
On packages embedding the BYPASS_REG pin, the regulator is enabled by holding
BYPASS_REG low. On all other packages, the regulator is always enabled.
There are three power modes configured by software when the regulator is ON:
•
MR mode used in Run/sleep modes or in Stop modes
–
In Run/Sleep modes
The MR mode is used either in the normal mode (default mode) or the over-drive
mode (enabled by software). A different voltage scaling is provided to reach the
best compromise between maximum frequency and dynamic power consumption.
The over-drive mode allows operating at a higher frequency than the normal mode
for a given voltage scaling.
–
In Stop modes
The MR can be configured in two ways during stop mode:
MR operates in normal mode (default mode of MR in stop mode)
MR operates in under-drive mode (reduced leakage mode).
•
LPR is used in the Stop modes:
The LP regulator mode is configured by software when entering Stop mode.
Like the MR mode, the LPR can be configured in two ways during stop mode:
•
–
LPR operates in normal mode (default mode when LPR is ON)
–
LPR operates in under-drive mode (reduced leakage mode).
Power-down is used in Standby mode.
The Power-down mode is activated only when entering in Standby mode. The regulator
output is in high impedance and the kernel circuitry is powered down, inducing zero
consumption. The contents of the registers and SRAM are lost.
Refer to Table 3 for a summary of voltage regulator modes versus device operating modes.
The VCAP_1 and VCAP_2 pins must be connected to 2*2.2 µF, ESR < 2 Ω (or 1*4.7 µF, ESR
between 0.1 Ω and 0.2 Ω if only the VCAP_1 pin is provided (on LQFP64 package)).
All the packages have the regulator ON feature.

3.16.2
Regulator OFF
This feature is available only on packages featuring the BYPASS_REG pin. The regulator is
disabled by holding BYPASS_REG high. The regulator OFF mode allows to supply
externally a V12 voltage source through VCAP_1 and VCAP_2 pins.
Since the internal voltage scaling is not managed internally, the external voltage value must
be aligned with the targeted maximum frequency.The two 2.2 µF ceramic capacitors should
be replaced by two 100 nF decoupling capacitors.
When the regulator is OFF, there is no more internal monitoring on V12. An external power
supply supervisor should be used to monitor the V12 of the logic power domain. The PA0 pin
should be used for this purpose, and act as power-on reset on V12 power domain.
In regulator OFF mode, the following features are no more supported:
•
PA0 cannot be used as a GPIO pin since it allows to reset a part of the V12 logic power
domain which is not reset by the NRST pin.
•
As long as PA0 is kept low, the debug mode cannot be used under power-on reset. As
a consequence, PA0 and NRST pins must be managed separately if the debug
connection under reset or pre-reset is required.
•
The over-drive and under-drive modes are not available.
•
The Standby mode is not available.

The following conditions must be respected:
•
VDD should always be higher than VCAP_1 and VCAP_2 to avoid current injection
between power domains.
•
If the time for VCAP_1 and VCAP_2 to reach V12 minimum value is faster than the time for
VDD to reach 1.7 V, then PA0 should be kept low to cover both conditions: until VCAP_1
and VCAP_2 reach V12 minimum value and until VDD reaches 1.7 V (see Figure 13).
•
Otherwise, if the time for VCAP_1 and VCAP_2 to reach V12 minimum value is slower
than the time for VDD to reach 1.7 V, then PA0 could be asserted low externally (see
Figure 14).
•
If VCAP_1 and VCAP_2 go below V12 minimum value and VDD is higher than 1.7 V, then a
reset must be asserted on PA0 pin.
Note:
The minimum value of V12 depends on the maximum frequency targeted in the application.
Note:
On the LQFP64 pin package, the VCAP_2 is not available.

Real-time clock (RTC), backup SRAM and backup registers
The RTC is an independent BCD timer/counter. It supports the following features:
•
Calendar with subsecond, seconds, minutes, hours (12 or 24 format), week day, date,
month, year, in BCD (binary-coded decimal) format.
•
Automatic correction for 28, 29 (leap year), 30, and 31 days of the month.
•
Two programmable alarms.
•
On-the-fly correction from 1 to 32767 RTC clock pulses. This can be used to
synchronize it with a master clock.
•
Reference clock detection: a more precise second source clock (50 or 60 Hz) can be
used to enhance the calendar precision.
•
Digital calibration circuit with 0.95 ppm resolution, to compensate for quartz crystal
inaccuracy.
•
Three anti-tamper detection pins with programmable filter.
•
Timestamp feature which can be used to save the calendar content. This function can
be triggered by an event on the timestamp pin, or by a tamper event, or by a switch to
VBAT mode.
•
17-bit auto-reload wakeup timer (WUT) for periodic events with programmable
resolution and period.
The RTC and the 32 backup registers are supplied through a switch that takes power either
from the VDD supply when present or from the VBAT pin.
The backup registers are 32-bit registers used to store 128 bytes of user application data
when VDD power is not present. They are not reset by a system or power reset, or when the
device wakes up from Standby mode.
The RTC clock sources can be:
•
A 32.768 kHz external crystal (LSE)
•
An external resonator or oscillator(LSE)
•
The internal low power RC oscillator (LSI, with typical frequency of 32 kHz)
•
The high-speed external clock (HSE) divided by 32
The RTC is functional in VBAT mode and in all low-power modes when it is clocked by the
LSE. When clocked by the LSI, the RTC is not functional in VBAT mode, but is functional in
all low-power modes.
36/230
DS11853 Rev 7
STM32F722xx STM32F723xx
Functional overview
All the RTC events (Alarm, WakeUp Timer, Timestamp or Tamper) can generate an interrupt
and wakeup the device from the low-power modes.
3.18
Low-power modes
The devices support three low-power modes to achieve the best compromise between low
power consumption, short startup time and available wakeup sources:
•
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.
•
Stop mode
The Stop mode achieves the lowest power consumption while retaining the contents of
SRAM and registers. All clocks in the 1.2 V domain are stopped, the PLL, the HSI RC
and the HSE crystal oscillators are disabled.
The voltage regulator can be put either in main regulator mode (MR) or in low-power
mode (LPR). Both modes can be configured as follows (see Table 5: Voltage regulator
modes in stop mode):
–
Normal mode (default mode when MR or LPR is enabled)
–
Under-drive mode.
The device can be woken up from the Stop mode by any of the EXTI line (the EXTI line
source can be one of the 16 external lines, the PVD output, the RTC alarm / wakeup /
tamper / time stamp events, the USB OTG FS/HS wakeup and the LPTIM1
asynchronous interrupt).

Standby mode
The Standby mode is used to achieve the lowest power consumption. The internal
voltage regulator is switched off so that the entire 1.2 V domain is powered off. The
PLL, the HSI RC and the HSE crystal oscillators are also switched off. After entering
Standby mode, the SRAM and register contents are lost except for registers in the
backup domain and the backup SRAM when selected.
The device exits the Standby mode when an external reset (NRST pin), an IWDG reset,
a rising or falling edge on one of the 6 WKUP pins (PA0, PA2, PC1, PC13, PI8, PI11),
or an RTC alarm / wakeup / tamper /time stamp event occurs.
The Standby mode is not supported when the embedded voltage regulator is bypassed
and the 1.2 V domain is controlled by an external power.

VBAT operation
The VBAT pin allows to power the device VBAT domain from an external battery, an external
supercapacitor, or from VDD when no external battery and an external supercapacitor are
present.
The VBAT operation is activated when VDD is not present.
The VBAT pin supplies the RTC, the backup registers and the backup SRAM.
Note:
When the microcontroller is supplied from VBAT, external interrupts and RTC alarm/events
do not exit it from VBAT operation.
When the PDR_ON pin is connected to VSS (Internal Reset OFF), the VBAT functionality is
no more available and the VBAT pin should be connected to VDD.

Timers and watchdogs
The devices include two advanced-control timers, eight general-purpose timers, two basic
timers and two watchdog timers.

3.20.1
STM32F722xx STM32F723xx
Advanced-control timers (TIM1, TIM8)
The advanced-control timers (TIM1, TIM8) can be seen as three-phase PWM generators
multiplexed on 6 channels. They have complementary PWM outputs with programmable
inserted dead times. They can also be considered as complete general-purpose timers.
Their 4 independent channels can be used for:
•
Input capture
•
Output compare
•
PWM generation (edge- or center-aligned modes)
•
One-pulse mode output
If configured as standard 16-bit timers, they have the same features as the general-purpose
TIMx timers. If configured as 16-bit PWM generators, they have full modulation capability (0100%).
The advanced-control timer can work together with the TIMx timers via the Timer Link
feature for synchronization or event chaining.
The TIM1 and TIM8 support independent DMA request generation.
3.20.2
General-purpose timers (TIMx)
There are ten synchronizable general-purpose timers embedded in the STM32F722xx and
STM32F723xx devices (see Table 6 for differences).
•
TIM2, TIM3, TIM4, TIM5
The STM32F722xx and STM32F723xx include 4 full-featured general-purpose timers:
TIM2, TIM5, TIM3, and TIM4.The TIM2 and TIM5 timers are based on a 32-bit autoreload up/downcounter and a 16-bit prescaler. The TIM3 and TIM4 timers are based on
a 16-bit auto-reload up/downcounter and a 16-bit prescaler. They all feature 4
independent channels for input capture/output compare, PWM or one-pulse mode
output. This gives up to 16 input capture/output compare/PWMs on the largest
packages.
The TIM2, TIM3, TIM4, TIM5 general-purpose timers can work together, or with the
other general-purpose timers and the advanced-control timers TIM1 and TIM8 via the
Timer Link feature for synchronization or event chaining.
Any of these general-purpose timers can be used to generate PWM outputs.
TIM2, TIM3, TIM4, TIM5 all have independent DMA request generation. They are
capable of handling quadrature (incremental) encoder signals and the digital outputs
from 1 to 4 hall-effect sensors.
•
TIM9, TIM10, TIM11, TIM12, TIM13, and TIM14
These timers are based on a 16-bit auto-reload upcounter and a 16-bit prescaler.
TIM10, TIM11, TIM13, and TIM14 feature one independent channel, whereas TIM9
and TIM12 have two independent channels for input capture/output compare, PWM or
one-pulse mode output. They can be synchronized with the TIM2, TIM3, TIM4, TIM5
full-featured general-purpose timers. They can also be used as simple time bases.
3.20.3
Basic timers TIM6 and TIM7
These timers are mainly used for the DAC trigger and waveform generation. They can also
be used as a generic 16-bit time base.
The TIM6 and TIM7 support independent DMA request generation.

Functional overview
Low-power timer (LPTIM1)
The low-power timer has an independent clock and is running also in Stop mode if it is
clocked by LSE, LSI or an external clock. It is able to wakeup the devices from Stop mode.
This low-power timer supports the following features:
3.20.5
•
16-bit up counter with 16-bit autoreload register
•
16-bit compare register
•
Configurable output: pulse, PWM
•
Continuous / one-shot mode
•
Selectable software / hardware input trigger
•
Selectable clock source:
•
Internal clock source: LSE, LSI, HSI or APB clock
•
External clock source over LPTIM input (working even with no internal clock source
running, used by the Pulse Counter Application)
•
Programmable digital glitch filter
•
Encoder mode
Independent watchdog
The independent watchdog is based on a 12-bit downcounter and 8-bit prescaler. It is
clocked from an independent 32 kHz internal RC and as it operates independently from the
main clock, it can operate in Stop and Standby modes. It can be used either as a watchdog
to reset the device when a problem occurs, or as a free-running timer for application timeout
management. It is hardware- or software-configurable through the option bytes.
3.20.6
Window watchdog
The window watchdog is based on a 7-bit downcounter that can be set as free-running. It
can be used as a watchdog to reset the device when a problem occurs. It is clocked from
the main clock. It has an early warning interrupt capability and the counter can be frozen in
debug mode.

Serial peripheral interface (SPI)/inter- integrated sound
interfaces (I2S)
The devices feature up to five SPIs in slave and master modes in full-duplex and simplex
communication modes. SPI1, SPI4, and SPI5 can communicate at up to 50 Mbit/s, SPI2
and SPI3 can communicate at up to 25 Mbit/s. The 3-bit prescaler gives 8 master mode
frequencies and the frame is configurable from 4 to 16 bits. The SPI interfaces support the
NSS pulse mode, TI mode and Hardware CRC calculation. All the SPIs can be served by
the DMA controller.
Three standard I2S interfaces (multiplexed with SPI1, SPI2 and SPI3) are available. They
can be operated in master or slave mode, in simplex communication modes, and can be
configured to operate with a 16-/32-bit resolution as an input or output channel. Audio
sampling frequencies from 8 kHz up to 192 kHz are supported. When either or both of the
I2S interfaces is/are configured in master mode, the master clock can be output to the
external DAC/CODEC at 256 times the sampling frequency.
All I2Sx can be served by the DMA controller.
3.24
Serial audio interface (SAI)
The devices embed two serial audio interfaces.
The serial audio interface is based on two independent audio subblocks which can operate
as transmitter or receiver with their FIFO. Many audio protocols are supported by each
block: I2S standards, LSB or MSB-justified, PCM/DSP, TDM, AC’97 and SPDIF output,
supporting audio sampling frequencies from 8 kHz up to 192 kHz. Both subblocks can be
configured in master or in slave mode.
In master mode, the master clock can be output to the external DAC/CODEC at 256 times of
the sampling frequency.
The two sub-blocks can be configured in synchronous mode when full-duplex mode is
required.

3.25
Audio PLL (PLLI2S)
The devices feature an additional dedicated PLL for audio I2S and SAI applications. It allows
to achieve an error-free I2S sampling clock accuracy without compromising on the CPU
performance, while using USB peripherals.
The PLLI2S configuration can be modified to manage an I2S/SAI sample rate change
without disabling the main PLL (PLL) used for CPU and USB interfaces.
The audio PLL can be programmed with very low error to obtain sampling rates ranging
from 8 KHz to 192 KHz.
In addition to the audio PLL, a master clock input pin can be used to synchronize the
I2S/SAI flow with an external PLL (or Codec output).
3.26
Audio PLL (PLLSAI)
An additional PLL dedicated to audio is used for the SAI1 peripheral in case the PLLI2S is
programmed to achieve another audio sampling frequency (49.152 MHz or 11.2896 MHz)
and the audio application requires both sampling frequencies simultaneously.
3.27
SD/SDIO/MMC card host interface (SDMMC)
SDMMC host interfaces are available, that support MultiMediaCard System Specification
Version 4.2 in three different databus modes: 1-bit (default), 4-bit and 8-bit.
The interface allows data transfer at up to 50 MHz, and is compliant with the SD Memory
Card Specification Version 2.0.
The SDMMC Card Specification Version 2.0 is also supported with two different databus
modes: 1-bit (default) and 4-bit.
The current version supports only one SD/SDMMC/MMC4.2 card at any one time and a
stack of MMC4.1 or previous.
The SDMMC can be served by the DMA controller
3.28
Controller area network (bxCAN)
The CAN is compliant with the 2.0A and B (active) specifications with a bit rate up to 1
Mbit/s. It can receive and transmit standard frames with 11-bit identifiers as well as
extended frames with 29-bit identifiers. The CAN has three transmit mailboxes, two receive
FIFOs with 3 stages and 28 shared scalable filter banks (all of them can be used even if one
CAN is used). 256 bytes of SRAM are allocated to the CAN.

peripheral. The USB OTG HS supports both full-speed and high-speed operations. It
integrates the transceivers for full-speed operation (12 Mbit/s).
The STM32F722xx devices feature a UTMI low-pin interface (ULPI) for high-speed
operation (480 Mbit/s). When using the USB OTG HS in HS mode, an external PHY device
connected to the ULPI is required.
The STM32F723xx devices feature an integrated PHY HS.
The USB OTG HS peripheral is compliant with the USB 2.0 specification and with the OTG
2.0 specification. It has a software-configurable endpoint setting and supports
suspend/resume. The USB OTG controller requires a dedicated 48 MHz clock that is

Random number generator (RNG)
All the devices embed an RNG that delivers 32-bit random numbers generated by an
integrated analog circuit.
3.32
General-purpose input/outputs (GPIOs)
Each of the GPIO pins can be configured by software as output (push-pull or open-drain,
with or without pull-up or pull-down), as input (floating, 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. All GPIOs are high-current-capable and have speed selection to better
manage internal noise, power consumption and electromagnetic emission.
The I/O configuration can be locked if needed by following a specific sequence in order to
avoid spurious writing to the I/Os registers.
A Fast I/O handling allows a maximum I/O toggling up to 108 MHz.
3.33
Analog-to-digital converters (ADCs)
Three 12-bit analog-to-digital converters are embedded and each ADC shares up to 16
external channels, performing conversions in the single-shot or scan mode. In the scan
mode, an automatic conversion is performed on a selected group of analog inputs.
Additional logic functions embedded in the ADC interface allow:
•
Simultaneous sample and hold
•
Interleaved sample and hold
The ADC can be served by the DMA controller. An analog watchdog feature allows very
precise monitoring of the converted voltage of one, some or all selected channels. An
interrupt is generated when the converted voltage is outside the programmed thresholds.
To synchronize A/D conversion and timers, the ADCs could be triggered by any of TIM1,
TIM2, TIM3, TIM4, TIM5, or TIM8 timer.

3.34
STM32F722xx STM32F723xx
Temperature sensor
The temperature sensor has to generate a voltage that varies linearly with the temperature.
The conversion range is between 1.7 V and 3.6 V. The temperature sensor is internally
connected to the same input channel as VBAT, ADC1_IN18, which is used to convert the
sensor output voltage into a digital value. When the temperature sensor and VBAT
conversion are enabled at the same time, only VBAT conversion is performed.
As the offset of the temperature sensor varies from chip to chip due to process variation, the
internal temperature sensor is mainly suitable for applications that detect temperature
changes instead of absolute temperatures. If an accurate temperature reading is needed,
then an external temperature sensor part should be used.
3.35
Digital-to-analog converter (DAC)
The two 12-bit buffered DAC channels can be used to convert two digital signals into two
analog voltage signal outputs.
This dual digital Interface supports the following features:
•
Two DAC converters: one for each output channel
•
8-bit or 12-bit monotonic output
•
Left or right data alignment in 12-bit mode
•
Synchronized update capability
•
Noise-wave generation
•
Triangular-wave generation
•
Dual DAC channel independent or simultaneous conversions
•
DMA capability for each channel
•
External triggers for conversion
•
Input voltage reference VREF+
Eight DAC trigger inputs are used in the device. The DAC channels are triggered through
the timer update outputs that are also connected to different DMA streams.
3.36
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.
The debug is performed using 2 pins only instead of 5 required by the JTAG (JTAG pins
could be re-used 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.

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
STM32F722xx and STM32F723xx device through a small number of ETM pins to an
external hardware trace port analyzer (TPA) device. The TPA is connected to a host
computer using the USB or any other high-speed channel. The real-time instruction and
data flow activity can be recorded and then formatted for display on the host computer that
runs the debugger software. The TPA hardware is commercially available from common
development tool vendors.
The Embedded Trace Macrocell operates with third party debugger software tools.

Table 10. STM32F722xx and STM32F723xx pin and ball definition (continued)
1. Function availability depends on the chosen device.
2. PC13, PC14, PC15 and PI8 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 and
PI8 in output mode is limited:
DS11853 Rev 7
- The speed should not exceed 2 MHz with a maximum load of 30 pF.
- These I/Os must not be used as a current source (e.g. to drive an LED).
3. Main function after the first backup domain power-up. Later on, it depends on the contents of the RTC registers even after reset (because these registers are not reset by
the main reset).
4. ULPI signals not available on the STM32F723xx devices.
5. If the device is in regulator OFF/internal reset ON mode (BYPASS_REG pin is set to VDD), then PA0 is used as an internal reset (active low).

Electrical characteristics
Parameter conditions
Unless otherwise specified, all voltages are referenced to VSS.
6.1.1
Minimum and maximum values
Unless otherwise specified the minimum and maximum values are guaranteed in the worst
conditions of ambient temperature, supply voltage and frequencies by tests in production on
100% of the devices with an ambient temperature at TA = 25 °C and TA = TAmax (given by
the selected temperature range).
Data based on characterization results, design simulation and/or technology characteristics
are indicated in the table footnotes. Based on characterization, the minimum and maximum
values refer to sample tests and represent the mean value plus or minus three times the
standard deviation (mean±3σ).
6.1.2
Typical values
Unless otherwise specified, typical data are based on TA = 25 °C, VDD = 3.3 V (for the
1.7 V ≤ VDD ≤ 3.6 V voltage range). They are given only as design guidelines and are not
tested.
Typical ADC accuracy values are determined by characterization of a batch of samples from
a standard diffusion lot over the full temperature range, where 95% of the devices have an
error less than or equal to the value indicated (mean±2σ).
6.1.3
Typical curves
Unless otherwise specified, all typical curves are given only as design guidelines and are
not tested.

3. The 4.7 µF ceramic capacitor must be connected to one of the VDD pin.
4. VDDA=VDD and VSSA=VSS.
Caution:
Each power supply pair (VDD/VSS, VDDA/VSSA ...) must be decoupled with filtering ceramic
capacitors as shown above. These capacitors must be placed as close as possible to, or
below, the appropriate pins on the underside of the PCB to ensure good operation of the
device. It is not recommended to remove filtering capacitors to reduce PCB size or cost.
This might cause incorrect operation of the device.

Note:
ADC accuracy vs. negative injection current: injecting a negative current on any analog
input pins should be avoided as this significantly reduces the accuracy of the conversion
being performed on another analog input. It is recommended to add a Schottky diode (pin to
ground) to analog pins which may potentially inject negative currents.
Any positive injection current within the limits specified for IINJ(PIN) and ΣIINJ(PIN) in
Section 6.3.20 does not affect the ADC accuracy.

1. Refer to Table 67 for the values of RAIN, RADC and CADC.
2. Cparasitic represents the capacitance of the PCB (dependent on soldering and PCB layout quality) plus the
pad capacitance (roughly 5 pF). A high Cparasitic value downgrades conversion accuracy. To remedy this,
fADC should be reduced.

General PCB design guidelines
Power supply decoupling should be performed as shown in Figure 50 or Figure 51,
depending on whether VREF+ is connected to VDDA or not. The 10 nF capacitors should be
ceramic (good quality). They should be placed them as close as possible to the chip.

I2C interface characteristics
The I2C interface meets the timings requirements of the I2C-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 1Mbit/s.
The I2C timings requirements are guaranteed by design when the I2C peripheral is properly
configured (refer to RM0431 reference manual) and when the I2CCLK frequency is greater
than the minimum shown in the table below:

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 VDD is disabled, but is still present.
The 20mA output drive requirement in Fast-mode Plus is not supported. This limits the
maximum load Cload supported in Fm+, which is given by these formulas:
•
Tr(SDA/SCL)=0.8473xRpxCload
•
Rp(min)= (VDD-VOL(max))/IOL(max)
Where Rp is the I2C lines pull-up. Refer to Section 6.3.20: I/O port characteristics for the
I2C I/Os characteristics.
All I2C SDA and SCL I/Os embed an analog filter. Refer to the table below for the analog

Note:
Refer to RM0431 reference manual I2S section for more details on the sampling frequency
(FS).
fMCK, fCK, and DCK values reflect only the digital peripheral behavior. The values of these
parameters might be slightly impacted by the source clock precision. DCK depends mainly
on the value of ODD bit. The digital contribution leads to a minimum value of
(I2SDIV/(2*I2SDIV+ODD) and a maximum value of (I2SDIV+ODD)/(2*I2SDIV+ODD). FS
maximum value is supported for each mode/condition.

1. All the voltages are measured from the local ground potential.
2. The USB OTG full speed transceiver functionality is ensured down to 2.7 V but not the full USB full speed
electrical characteristics which are degraded in the 2.7-to-3.0 V VDDUSB voltage range.
3. Guaranteed by design.
4. RL is the load connected on the USB OTG full speed drivers.
Note:
When VBUS sensing feature is enabled, PA9 and PB13 should be left at their default state
(floating input), not as alternate function. A typical 200 µA current consumption of the
sensing block (current to voltage conversion to determine the different sessions) can be
observed on PA9 and PB13 when the feature is enabled.

Synchronous waveforms and timings
Figure 66 through Figure 69 represent synchronous waveforms and Table 101 through
Table 104 provide the corresponding timings. The results shown in these tables are
obtained with the following FMC configuration:
•
BurstAccessMode = FMC_BurstAccessMode_Enable;
•
MemoryType = FMC_MemoryType_CRAM;
•
WriteBurst = FMC_WriteBurst_Enable;
•
CLKDivision = 1;
•
DataLatency = 1 for NOR Flash; DataLatency = 0 for PSRAM
•
CL = 30 pF on data and address lines. CL = 10 pF on FMC_CLK unless otherwise
specified.
In all timing tables, the THCLK is the HCLK clock period.
–
For 2.7 V≤ VDD≤ 3.6 V, maximum FMC_CLK = 108 MHz at CL=20 pF or 90 MHz at
CL=30 pF (on FMC_CLK).
