Description
Description
The STM32F411XC/XE devices are based on the high-performance ARM® Cortex® -M4 32bit RISC core operating at a frequency of up to 100 MHz. Its Cortex®-M4 core features a
Floating point unit (FPU) single precision which supports all ARM single-precision dataprocessing instructions and data types. It also implements a full set of DSP instructions and
a memory protection unit (MPU) which enhances application security.
The STM32F411xC/xE belongs to the STM32 Dynamic Efficiency™ product line (with
products combining power efficiency, performance and integration) while adding a new
innovative feature called Batch Acquisition Mode (BAM) allowing to save even more power
consumption during data batching.
The STM32F411xC/xE incorporate high-speed embedded memories (up to 512 Kbytes of
Flash memory, 128 Kbytes of SRAM), and an extensive range of enhanced I/Os and
peripherals connected to two APB buses, two AHB bus and a 32-bit multi-AHB bus matrix.
All devices offer one 12-bit ADC, a low-power RTC, six general-purpose 16-bit timers
including one PWM timer for motor control, two general-purpose 32-bit timers. They also
feature standard and advanced communication interfaces.

Functional overview
3.1
ARM® Cortex®-M4 with FPU core with embedded Flash and
SRAM
The ARM® Cortex®-M4 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 an advanced response to interrupts.
The ARM® Cortex®-M4 with FPU 32-bit RISC processor features exceptional codeefficiency, delivering the high-performance expected from an ARM core in the memory size
usually associated with 8- and 16-bit devices. The processor supports a set of DSP
instructions which allow efficient signal processing and complex algorithm execution. Its
single precision FPU (floating point unit) speeds up software development by using
metalanguage development tools, while avoiding saturation.
The STM32F411xC/xE devices are compatible with all ARM tools and software.
Figure 3 shows the general block diagram of the STM32F411xC/xE.
Note:
Cortex®-M4 with FPU is binary compatible with Cortex®-M3.
3.2
Adaptive real-time memory accelerator (ART Accelerator™)
The ART Accelerator™ is a memory accelerator which is optimized for STM32 industrystandard ARM® Cortex®-M4 with FPU processors. It balances the inherent performance
advantage of the ARM® Cortex®-M4 with FPU over Flash memory technologies, which
normally requires the processor to wait for the Flash memory at higher frequencies.
To release the processor full 105 DMIPS performance at this frequency, the accelerator
implements an instruction prefetch queue and branch cache, which increases program
execution speed from the -bit Flash memory. Based on CoreMark benchmark, the
performance achieved thanks to the ART accelerator is equivalent to 0 wait state program
execution from Flash memory at a CPU frequency up to 100 MHz.
3.3
Batch Acquisition mode (BAM)
The Batch acquisition mode allows enhanced power efficiency during data batching. It
enables data acquisition through any communication peripherals directly to memory using
the DMA in reduced power consumption as well as data processing while the rest of the
system is in low-power mode (including the flash and ART). For example in an audio
system, a smart combination of PDM audio sample acquisition and processing from the I2S
directly to RAM (flash and ART™ stopped) with the DMA using BAM followed by some very
short processing from flash allows to drastically reduce the power consumption of the
application. A dedicated application note (AN4515) describes how to implement the
STM32F411xC/xE BAM to allow the best power efficiency.

DocID026289 Rev 4

3.4
Functional overview
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.
3.5
Embedded Flash memory
The devices embed up to 512 Kbytes of Flash memory available for storing programs and
data.
To optimize the power consumption the Flash memory can also be switched off in Run or in
Sleep mode (see Section 3.18: Low-power modes). Two modes are available: Flash in Stop
mode or in DeepSleep mode (trade off between power saving and startup time, see
Table 34: Low-power mode wakeup timings(1)). Before disabling the Flash, the code must
be executed from the internal RAM.
3.6
CRC (cyclic redundancy check) calculation unit
The CRC (cyclic redundancy check) calculation unit is used to get a CRC code from a 32-bit
data word and a fixed generator polynomial.
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 software
signature during runtime, to be compared with a reference signature generated at link-time
and stored at a given memory location.
3.7
Embedded SRAM
All devices embed:
•
3.8
128 Kbytes of system SRAM which can be accessed (read/write) at CPU clock speed
with 0 wait states
Multi-AHB bus matrix
The 32-bit multi-AHB bus matrix interconnects all the masters (CPU, DMAs) and the slaves
(Flash memory, RAM, AHB and APB peripherals) and ensures a seamless and efficient
operation even when several high-speed peripherals work simultaneously.

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 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. Configuration is made by software and transfer sizes between
source and destination are independent.
The DMA can be used with the main peripherals:

Nested vectored interrupt controller (NVIC)
The devices embed a nested vectored interrupt controller able to manage 16 priority levels,
and handle up to 62 maskable interrupt channels plus the 16 interrupt lines of the
Cortex®-M4 with FPU.

•
Processing of late arriving, higher-priority interrupts
•

•
Processor state automatically saved
•
Interrupt entry restored on interrupt exit with no instruction overhead
This hardware block provides flexible interrupt management features with minimum interrupt
latency.
3.11
External interrupt/event controller (EXTI)
The external interrupt/event controller consists of 21 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 81 GPIOs can be connected
to the 16 external interrupt lines.
3.12
Clocks and startup
On reset the 16 MHz internal RC oscillator is selected as the default CPU clock. The
16 MHz internal RC oscillator is factory-trimmed to offer 1% accuracy at 25 °C. 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 100 MHz. Similarly, 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 100 MHz while the maximum frequency of the high-speed APB domains is
100 MHz. The maximum allowed frequency of the low-speed APB domain is 50 MHz.
The devices embed a dedicated PLL (PLLI2S) which allows to achieve audio class
performance. In this case, the I2S master clock can generate all standard sampling
frequencies from 8 kHz to 192 kHz.

Boot modes
At startup, boot pins are used to select one out of three boot options:
•
Boot from user Flash
•
Boot from system memory
•
Boot from embedded SRAM
The boot loader is located in system memory. It is used to reprogram the Flash memory by
using USART1(PA9/10), USART2(PD5/6), USB OTG FS in device mode (PA11/12) through
DFU (device firmware upgrade), I2C1(PB6/7), I2C2(PB10/3), I2C3(PA8/PB4),
SPI1(PA4/5/6/7), SPI2(PB12/13/14/15) or SPI3(PA15, PC10/11/12).
For more detailed information on the bootloader, refer to Application Note: AN2606,
STM32™ microcontroller system memory boot mode.

Power supply schemes
•
VDD = 1.7 to 3.6 V: external power supply for I/Os with the internal supervisor
(POR/PDR) disabled, provided externally through VDD pins. Requires the use of an
external power supply supervisor connected to the VDD and NRST pins.
•
VSSA, VDDA = 1.7 to 3.6 V: external analog power supplies for ADC, Reset blocks, RCs
and PLL. VDDA and VSSA must be connected to VDD and VSS, respectively, with
decoupling technique.
•
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.
Refer to Figure 17: Power supply scheme for more details.

Power supply supervisor
3.15.1
Internal reset ON
This feature is available for VDD operating voltage range 1.8 V to 3.6 V.
The internal power supply supervisor is enabled by holding PDR_ON high.
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 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
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 by setting the PDR_ON pin to
low.
An external power supply supervisor should monitor VDD and should set the device in reset
mode when VDD is below 1.7 V. NRST should be connected to this external power supply
supervisor. Refer to Figure 5: Power supply supervisor interconnection with internal reset
OFF.

A comprehensive set of power-saving mode allows to design low-power applications.
When the internal reset is OFF, the following integrated features are no longer supported:
3.16
•
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.
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 is used in the nominal regulation mode (With different voltage scaling in Run)
In Main regulator mode (MR mode), different voltage scaling are provided to reach the
best compromise between maximum frequency and dynamic power consumption.
•
LPR is used in the Stop modes
The LP regulator mode is configured by software when entering Stop 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.
Depending on the package, one or two external ceramic capacitors should be connected on
the VCAP_1 and VCAP_2 pins. The VCAP_2 pin is only available for the LQFP100 and
UFBGA100 packages.
All packages have the regulator ON feature.
3.16.2
Regulator OFF
The Regulator OFF is available only on the UFBGA100, which features 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.
22/146
DocID026289 Rev 4
STM32F411xC STM32F411xE
Functional overview
Since the internal voltage scaling is not managed internally, the external voltage value must
be aligned with the targeted maximum frequency. Refer to Table 14: General operating
conditions.
The two 2.2 µF VCAP ceramic capacitors should be replaced by two 100 nF decoupling
capacitors. Refer to Figure 18: Power supply scheme.
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. 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 following conditions must be respected:
Note:
•
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 7).
•
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 8).
•
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.
The minimum value of V12 depends on the maximum frequency targeted in the application

Real-time clock (RTC) and backup registers
The backup domain includes:
•
The real-time clock (RTC)
•
20 backup registers
The real-time clock (RTC) is an independent BCD timer/counter. Dedicated registers contain
the second, minute, hour (in 12/24 hour), week day, date, month, year, in BCD (binarycoded decimal) format. Correction for 28, 29 (leap year), 30, and 31 day of the month are
performed automatically. The RTC features a reference clock detection, a more precise
second source clock (50 or 60 Hz) can be used to enhance the calendar precision. The RTC
provides a programmable alarm and programmable periodic interrupts with wakeup from
Stop and Standby modes. The sub-seconds value is also available in binary format.
It is clocked by a 32.768 kHz external crystal, resonator or oscillator, the internal low-power
RC oscillator or the high-speed external clock divided by 128. The internal low-speed RC
has a typical frequency of 32 kHz. The RTC can be calibrated using an external 512 Hz
output to compensate for any natural quartz deviation.
Two alarm registers are used to generate an alarm at a specific time and calendar fields can
be independently masked for alarm comparison. To generate a periodic interrupt, a 16-bit
programmable binary auto-reload downcounter with programmable resolution is available
and allows automatic wakeup and periodic alarms from every 120 µs to every 36 hours.
A 20-bit prescaler is used for the time base clock. It is by default configured to generate a
time base of 1 second from a clock at 32.768 kHz.
The backup registers are 32-bit registers used to store 80 bytes of user application data
when VDD power is not present. Backup registers are not reset by a system, a power reset,
or when the device wakes up from the Standby mode (see Section 3.18: Low-power
modes).
Additional 32-bit registers contain the programmable alarm subseconds, seconds, minutes,
hours, day, and date.
DocID026289 Rev 4

Functional overview
STM32F411xC STM32F411xE
The RTC and backup registers are supplied through a switch that is powered either from the
VDD supply when present or from the VBAT pin.
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.
To further reduce the power consumption, the Flash memory can be switched off
before entering in Sleep mode. Note that this requires a code execution from the RAM.
•
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 also be put
either in normal or in low-power 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).
•
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 when selected.
The device exits the Standby mode when an external reset (NRST pin), an IWDG reset,
a rising edge on the WKUP pin, or an RTC alarm/ wakeup/ tamper/time stamp event
occurs.
Standby mode is not supported when the embedded voltage regulator is bypassed and
the 1.2 V domain is controlled by an external power.
3.19
VBAT operation
The VBAT pin allows to power the device VBAT domain from an external battery, an external
super-capacitor, or from VDD when no external battery and an external super-capacitor are
present.
VBAT operation is activated when VDD is not present.
The VBAT pin supplies the RTC and the backup registers.
Note:
26/146
When the microcontroller is supplied from VBAT, external interrupts and RTC alarm/events
do not exit it from VBAT operation. When PDR_ON pin is not connected to VDD (internal
Reset OFF), the VBAT functionality is no more available and VBAT pin should be connected
to VDD.

Advanced-control timers (TIM1)
The advanced-control timer (TIM1) can be seen as three-phase PWM generators
multiplexed on 4 independent channels. It has complementary PWM outputs with
programmable inserted dead times. It can also be considered as a complete generalpurpose timer. Its 4 independent channels can be used for:
•
Input capture
•
Output compare
•
PWM generation (edge- or center-aligned modes)
•
One-pulse mode output
DocID026289 Rev 4

Functional overview
STM32F411xC STM32F411xE
If configured as standard 16-bit timers, it has the same features as the general-purpose
TIMx timers. If configured as a 16-bit PWM generator, it has 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.
TIM1 supports independent DMA request generation.
3.20.2
General-purpose timers (TIMx)
There are seven synchronizable general-purpose timers embedded in the
STM32F411xC/xE (see Table 4 for differences).
•
TIM2, TIM3, TIM4, TIM5
The STM32F411xC/xE devices are 4 full-featured general-purpose timers: TIM2, TIM5,
TIM3, and TIM4.The TIM2 and TIM5 timers are based on a 32-bit auto-reload
up/downcounter and a 16-bit prescaler. The TIM3 and TIM4 timers are based on a 16bit auto-reload up/downcounter and a 16-bit prescaler. They all feature four
independent channels for input capture/output compare, PWM or one-pulse mode
output. This gives up to 15 input capture/output compare/PWMs.
The TIM2, TIM3, TIM4, TIM5 general-purpose timers can work together, or with the
other general-purpose timers and the advanced-control timer TIM1 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 and TIM11
These timers are based on a 16-bit auto-reload upcounter and a 16-bit prescaler.
TIM10 and TIM11 feature one independent channel, whereas TIM9 has 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
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.
3.20.4
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.

downcounter. It features:
3.21
•
A 24-bit downcounter
•
Autoreload capability
•
Maskable system interrupt generation when the counter reaches 0
•
Programmable clock source.
Inter-integrated circuit interface (I2C)
Up to three I2C bus interfaces can operate in multimaster and slave modes. They can
support the standard (up to 100 kHz) and fast (up to 400 kHz) modes. The I2C bus
frequency can be increased up to 1 MHz. For more details about the complete solution,
please contact your local ST sales representative.They also support the 7/10-bit addressing
mode and the 7-bit dual addressing mode (as slave). A hardware CRC
generation/verification is embedded.
They can be served by DMA and they support SMBus 2.0/PMBus.
The devices also include programmable analog and digital noise filters (see Table 5).

(USART)
The devices embed three universal synchronous/asynchronous receiver transmitters
(USART1, USART2 and USART6).
These three interfaces provide asynchronous communication, IrDA SIR ENDEC support,
multiprocessor communication mode, single-wire half-duplex communication mode and
have LIN Master/Slave capability. The USART1 and USART6 interfaces are able to
communicate at speeds of up to 12.5 Mbit/s. The USART2 interface communicates at up to
6.25 bit/s.

Serial peripheral interface (SPI)
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 to 8 bits or 16 bits. The hardware CRC
generation/verification supports basic SD Card/MMC modes. All SPIs can be served by the
DMA controller.
The SPI interface can be configured to operate in TI mode for communications in master
mode and slave mode.
3.24
Inter-integrated sound (I2S)
Five standard I2S interfaces (multiplexed with SPI1 to SPI5) are available.They can be
operated in master or slave mode, in simplex communication modes and full duplex for I2S2
and I2S3 and can be configured to operate with a 16-/32-bit resolution as an input or output
channel. All the I2Sx 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.
3.25
Audio PLL (PLLI2S)
The devices feature an additional dedicated PLL for audio I2S application. It allows to
achieve error-free I2S sampling clock accuracy without compromising on the CPU
performance.
The PLLI2S configuration can be modified to manage an I2S sample rate change without
disabling the main PLL (PLL) used for the CPU.
The audio PLL can be programmed with very low error to obtain sampling rates ranging
from 8 kHz to 192 kHz.
30/146
DocID026289 Rev 4
STM32F411xC STM32F411xE
Functional overview
In addition to the audio PLL, a master clock input pin can be used to synchronize the I2S
flow with an external PLL (or Codec output).
3.26
Secure digital input/output interface (SDIO)
An SD/SDIO/MMC/eMMC host interface is available, that supports 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 SDIO 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/SDIO/MMC4.2 card at any one time and a stack
of MMC4.1 or previous.
In addition to SD/SDIO/MMC/eMMC, this interface is fully compliant with the CE-ATA digital
protocol Rev1.1.
3.27
Universal serial bus on-the-go full-speed (OTG_FS)
The devices embed an USB OTG full-speed device/host/OTG peripheral with integrated
transceivers. The USB OTG FS peripheral is compliant with the USB 2.0 specification and
with the OTG 1.0 specification. It has software-configurable endpoint setting and supports
suspend/resume. The USB OTG full-speed controller requires a dedicated 48 MHz clock
that is generated by a PLL connected to the HSE oscillator. The major features are:
3.28
•
Combined Rx and Tx FIFO size of 320 × 35 bits with dynamic FIFO sizing
•
Supports the session request protocol (SRP) and host negotiation protocol (HNP)
•
4 bidirectional endpoints
•
8 host channels with periodic OUT support
•
HNP/SNP/IP inside (no need for any external resistor)
•
For OTG/Host modes, a power switch is needed in case bus-powered devices are
connected
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.
Fast I/O handling allowing maximum I/O toggling up to 100 MHz.

3.29
STM32F411xC STM32F411xE
Analog-to-digital converter (ADC)
One 12-bit analog-to-digital converter is embedded and shares up to 16 external channels,
performing conversions in the single-shot or scan mode. In scan mode, automatic
conversion is performed on a selected group of analog inputs.
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 or TIM5 timer.
3.30
Temperature sensor
The temperature sensor has to generate a voltage that varies linearly with temperature. The
conversion range is between 1.7 V and 3.6 V. The temperature sensor is internally
connected to the ADC_IN18 input channel which is used to convert the sensor output
voltage into a digital value. Refer to the reference manual for additional information.
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.
3.31
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.
3.32
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
STM32F411xC/xE 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 any high-speed
channel available. Real-time instruction and data flow activity can 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 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). For details on how to manage these I/Os, refer to the RTC
register description sections in the STM32F411xx reference manual.
4. FT = 5 V tolerant except when in analog mode or oscillator mode (for PC14, PC15, PH0 and PH1).
5. If the device is delivered in an UFBGA100 and the BYPASS_REG pin is set to VDD (Regulator off/internal reset ON mode),
then PA0 is used as an internal Reset (active low)

6.1
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 and are not tested in production. 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 ±3 σ).
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 ±2 σ).
6.1.3
Typical curves
Unless otherwise specified, all typical curves are given only as design guidelines and are
not tested.

1. To connect PDR_ON pin, refer to Section 3.15: Power supply supervisor.
2. The 4.7 µF ceramic capacitor must be connected to one of the VDD pin.
3. VCAP_2 pad is only available on LQFP100 and UFBGA100 packages.
4. VDDA=VDD and VSSA=VSS.
Caution:
Each power supply pair (for example 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.

2. When the ADC is used, refer to Table 65: ADC characteristics.
3. If VREF+ pin is present, it must respect the following condition: VDDA-VREF+ < 1.2 V.
4. It is recommended to power VDD and VDDA from the same source. A maximum difference of 300 mV between VDD and
VDDA can be tolerated during power-up and power-down operation.
5. Guaranteed by test in production
6. To sustain a voltage higher than VDD+0.3, the internal Pull-up and Pull-Down resistors must be disabled
7. If TA is lower, higher PD values are allowed as long as TJ does not exceed TJmax.
8. In low power dissipation state, TA can be extended to this range as long as TJ does not exceed TJmax.

1. Applicable only when the code is executed from Flash memory. When the code is executed from RAM, no wait state is
required.
2. Thanks to the ART accelerator and the 128-bit Flash memory, the number of wait states given here does not impact the
execution speed from Flash memory since the ART accelerator allows to achieve a performance equivalent to 0 wait state
program execution.
3. Refer to Table 55: I/O AC characteristics for frequencies vs. external load.
4. VDD/VDDA minimum value of 1.7 V, with the use of an external power supply supervisor (refer to Section 3.15.2: Internal
reset OFF).
5. Prefetch is not available. Refer to AN3430 application note for details on how to adjust performance and power.
6. The voltage range for the USB full speed embedded PHY can drop down to 2.7 V. However the electrical characteristics of
D- and D+ pins will be degraded between 2.7 and 3 V.
6.3.2
VCAP1/VCAP2 external capacitors
Stabilization for the main regulator is achieved by connecting the external capacitor CEXT to
the VCAP1 and VCAP2 pins. For packages supporting only 1 VCAP pin, the 2 CEXT
capacitors are replaced by a single capacitor.
CEXT is specified in Table 16.

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 18: Current consumption
measurement scheme.
All the run-mode current consumption measurements given in this section are performed
with a reduced code that gives a consumption equivalent to CoreMark code.

Electrical characteristics
Typical and maximum current consumption
The MCU is placed under the following conditions:
•
All I/O pins are in input mode with a static value at VDD or VSS (no load).
•
All peripherals are disabled except if it is explicitly mentioned.
•
The Flash memory access time is adjusted to both fHCLK frequency and VDD ranges
(refer to Table 15: Features depending on the operating power supply range).
•
The voltage scaling is adjusted to fHCLK frequency as follows:
–
Scale 3 for fHCLK ≤ 64 MHz
–
Scale 2 for 64 MHz < fHCLK ≤ 84 MHz
–
Scale 1 for 84 MHz < fHCLK ≤ 100 MHz
•
The system clock is HCLK, fPCLK1 = fHCLK/2, and fPCLK2 = fHCLK.
•
External clock is 4 MHz and PLL is ON except if it is explicitly mentioned.
•
The maximum values are obtained for VDD = 3.6 V and a maximum ambient
temperature (TA), and the typical values for TA= 25 °C and VDD = 3.3 V unless
otherwise specified.

I/O 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 53: I/O static characteristics.
For the output pins, any external pull-down or external load must also be considered to
estimate the current consumption.
DocID026289 Rev 4
75/146
119
Electrical characteristics
STM32F411xC STM32F411xE
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 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 can be 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 (see Table 33: Peripheral current
consumption), 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 MCU supply voltage to supply the I/O
pin circuitry and to charge/discharge the capacitive load (internal or external) connected to
the pin:
I SW = V DD × f SW × C
where
ISW is the current sunk by a switching I/O to charge/discharge the capacitive load
VDD is the MCU supply voltage
fSW is the I/O switching frequency
C is the total capacitance seen by the I/O pin: C = CINT+ CEXT
The test pin is configured in push-pull output mode and is toggled by software at a fixed
frequency.

High-speed external clock generated from a crystal/ceramic resonator
The high-speed external (HSE) clock can be supplied with a 4 to 26 MHz crystal/ceramic
resonator oscillator. All the information given in this paragraph are based on
characterization results obtained with typical external components specified in Table 37. 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).

For CL1 and CL2, it is recommended to use high-quality external ceramic capacitors in the
5 pF to 25 pF range (Typ.), designed for high-frequency applications, and selected to match
the requirements of the crystal or resonator (see Figure 24). CL1 and CL2 are usually the
same size. The crystal manufacturer typically specifies a load capacitance which is the

can be used as a rough estimate of the combined pin and board capacitance) when sizing
CL1 and CL2.

Equation 1
The frequency modulation period (MODEPER) is given by the equation below:
MODEPER = round [ f PLL_IN ⁄ ( 4 × fMod ) ]
fPLL_IN and fMod must be expressed in Hz.
As an example:
If fPLL_IN = 1 MHz, and fMOD = 1 kHz, the modulation depth (MODEPER) is given by
equation 1:
6
3
MODEPER = round [ 10 ⁄ ( 4 × 10 ) ] = 250
Equation 2
Equation 2 allows to calculate the increment step (INCSTEP):
INCSTEP = round [ ( ( 2
15
– 1 ) × md × PLLN ) ⁄ ( 100 × 5 × MODEPER ) ]
fVCO_OUT must be expressed in MHz.
With a modulation depth (md) = ±2 % (4 % peak to peak), and PLLN = 240 (in MHz):
INCSTEP = round [ ( ( 2
15
– 1 ) × 2 × 240 ) ⁄ ( 100 × 5 × 250 ) ] = 126md(quantitazed)%
An amplitude quantization error may be generated because the linear modulation profile is
obtained by taking the quantized values (rounded to the nearest integer) of MODPER and
INCSTEP. As a result, the achieved modulation depth is quantized. The percentage
quantized modulation depth is given by the following formula:
md quantized % = ( MODEPER × INCSTEP × 100 × 5 ) ⁄ ( ( 2
15
– 1 ) × PLLN )
As a result:
md quantized % = ( 250 × 126 × 100 × 5 ) ⁄ ( ( 2

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 VDD and VSS
through a 100 pF capacitor, until a functional disturbance occurs. This test is 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.

When the application is exposed to a noisy environment, it is recommended to avoid pin
exposition to disturbances. The pins showing a middle range robustness are: PA0, PA1,
PA2, on LQFP100 packages and PDR_ON on WLCSP49.
As a consequence, it is recommended to add a serial resistor (1 kΩ maximum) located as
close as possible to the MCU to the pins exposed to noise (connected to tracks longer than
50 mm on PCB).
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.
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).

Absolute maximum ratings (electrical sensitivity)
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 JESD22-A114/C101 standard.

I/O current injection characteristics
As a general rule, current injection to the I/O pins, due to external voltage below VSS or
above VDD (for standard, 3 V-capable I/O pins) should be avoided during normal product
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 (>5
LSB TUE), out of conventional limits of induced leakage current on adjacent pins
(out of –5 µA/+0 µA range), or other functional failure (for example reset, oscillator
frequency deviation).
Negative induced leakage current is caused by negative injection and positive induced
leakage current by positive injection.
The test results are given in Table 52.

I2C interface characteristics
The I2C interface meets the requirements of the standard I2C communication protocol with
the following restrictions: the I/O pins SDA and SCL are mapped to are not “true” opendrain. When configured as open-drain, the PMOS connected between the I/O pin and VDD is
disabled, but is still present.
The I2C characteristics are described in Table 58. Refer also to Section 6.3.16: I/O port
characteristics for more details on the input/output alternate function characteristics (SDA
and SCL).
The I2C bus interface supports standard mode (up to 100 kHz) and fast mode (up to 400
kHz). The I2C bus frequency can be increased up to 1 MHz. For more details about the
complete solution, please contact your local ST sales representative.

2. The maximum value of 256xFs is 50 MHz (APB1 maximum frequency).
Note:
Refer to the I2S section of RM0383 reference manual 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.

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 6.3.16 does not affect the ADC accuracy.

1. Refer to Table 65 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 42 or Figure 43,
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.

Thermal characteristics
The maximum chip junction temperature (TJmax) must never exceed the values given in
Table 14: General operating conditions on page 60.
The maximum chip-junction temperature, TJ max., in degrees Celsius, may be calculated
using the following equation:
TJ max = TA max + (PD max x ΘJA)
Where:
•
TA max is the maximum ambient temperature in °C,
•
ΘJA is the package junction-to-ambient thermal resistance, in °C/W,
•
PD max is the sum of PINT max and PI/O max (PD max = PINT max + PI/Omax),
•
PINT max is the product of IDD and VDD, expressed in Watts. This is the maximum chip
internal power.
PI/O max represents the maximum power dissipation on output pins where:
PI/O max = Σ (VOL × IOL) + Σ((VDD – VOH) × IOH),
taking into account the actual VOL / IOL and VOH / IOH of the I/Os at low and high level in the
application.

Recommendations when using the internal reset OFF
Recommendations when using the internal
reset OFF
When the internal reset is OFF, the following integrated features are no longer supported:
A.1
•
The integrated power-on-reset (POR)/power-down reset (PDR) circuitry is disabled.
•
The brownout reset (BRO) circuitry must be disabled. By default BOR is OFF.
•
The embedded programmable voltage detector (PVD) is disabled.
•
VBAT functionality is no more available and VBAT pin should be connected to VDD.

1. Applicable only when the code is executed from Flash memory. When the code is executed from RAM, no
wait state is required.
2. Thanks to the ART accelerator and the 128-bit Flash memory, the number of wait states given here does
not impact the execution speed from Flash memory since the ART accelerator allows to achieve a
performance equivalent to 0 wait state program execution.
3. VDD/VDDA minimum value of 1.7 V, with the use of an external power supply supervisor (refer to
Section 3.15.1: Internal reset ON).
4. Prefetch is not available. Refer to AN3430 application note for details on how to adjust performance and
power.
