DocID022152 Rev 4 11/185 Description 2 STM32F405xx, STM32F407xx Description The STM32F405xx and STM32F407xx family is based on the high-performance ARM® Cortex™-M4 32-bit RISC core operating at a frequency of up to 168 MHz. The Cortex-M4 core features a Floating point unit (FPU) single precision which supports all ARM singleprecision data-processing instructions and data types. It also implements a full set of DSP instructions and a memory protection unit (MPU) which enhances application security.

They are fully pinto-pin, software and feature compatible with the STM32F2xx devices, allowing the user to try different memory densities, peripherals, and performances (FPU, higher frequency) for a greater degree of freedom during the development cycle. The STM32F405xx and STM32F407xx devices maintain a close compatibility with the whole STM32F10xxx family. All functional pins are pin-to-pin compatible. The STM32F405xx and STM32F407xx, however, are not drop-in replacements for the STM32F10xxx devices: the two families do not have the same power scheme, and so their power pins are different. Nonetheless, transition from the STM32F10xxx to the STM32F40x family remains simple as only a few pins are impacted. Figure 4, Figure 3, Figure 2, and Figure 1 give compatible board designs between the STM32F40x, STM32F2xxx, and STM32F10xxx families. Figure 1.

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-M4F 32-bit RISC processor features exceptional code-efficiency, 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 STM32F405xx and STM32F407xx family is compatible with all ARM tools and software. Figure 5 shows the general block diagram of the STM32F40x family. Note: Cortex-M4F is binary compatible with Cortex-M3. 2.2.2 Adaptive real-time memory accelerator (ART Accelerator™) The ART Accelerator™ is a memory accelerator which is optimized for STM32 industrystandard ARM® Cortex™-M4F processors. It balances the inherent performance advantage of the ARM Cortex-M4F over Flash memory technologies, which normally requires the processor to wait for the Flash memory at higher frequencies. To release the processor full 210 DMIPS performance at this frequency, the accelerator implements an instruction prefetch queue and branch cache, which increases program execution speed from the 128-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 168 MHz. 2.2.3 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. 2.2.4 Embedded Flash memory The STM32F40x devices embed a Flash memory of 512 Kbytes or 1 Mbytes available for storing programs and data. DocID022152 Rev 4 19/185 Description 2.2.5 STM32F405xx, STM32F407xx 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. 2.2.6 Embedded SRAM All STM32F40x products embed: • Up to 192 Kbytes of system SRAM including 64 Kbytes of CCM (core coupled memory) data RAM RAM memory is accessed (read/write) 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. 2.2.7 Multi-AHB bus matrix The 32-bit multi-AHB bus matrix interconnects all the masters (CPU, DMAs, Ethernet, USB HS) and the slaves (Flash memory, RAM, FSMC, AHB and APB peripherals) and ensures a seamless and efficient operation even when several high-speed peripherals work simultaneously. 20/185 DocID022152 Rev 4 STM32F405xx, STM32F407xx Description Figure 6.

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: • SPI and I2S • I2C • USART • General-purpose, basic and advanced-control timers TIMx • DAC • SDIO • Camera interface (DCMI) • ADC. DocID022152 Rev 4 21/185 Description 2.2.9 STM32F405xx, STM32F407xx Flexible static memory controller (FSMC) The FSMC is embedded in the STM32F405xx and STM32F407xx family. It has four Chip Select outputs supporting the following modes: PCCard/Compact Flash, SRAM, PSRAM, NOR Flash and NAND Flash. Functionality overview: • Write FIFO • Maximum FSMC_CLK frequency for synchronous accesses is 60 MHz. LCD parallel interface The FSMC 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. 2.2.10 Nested vectored interrupt controller (NVIC) The STM32F405xx and STM32F407xx embed a nested vectored interrupt controller able to manage 16 priority levels, and handle up to 82 maskable interrupt channels plus the 16 interrupt lines of the Cortex™-M4F. • 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 minimum interrupt latency. 2.2.11 External interrupt/event controller (EXTI) The external interrupt/event controller consists of 23 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 can be connected to the 16 external interrupt lines. 2.2.12 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 over the full temperature range. 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 168 MHz. Similarly, full interrupt management of the PLL 22/185 DocID022152 Rev 4 STM32F405xx, STM32F407xx Description clock entry is available when necessary (for example if an indirectly used external oscillator fails). Several prescalers allow the configuration of the three AHB buses, the high-speed APB (APB2) and the low-speed APB (APB1) domains. The maximum frequency of the three AHB buses is 168 MHz while the maximum frequency of the high-speed APB domains is 84 MHz. The maximum allowed frequency of the low-speed APB domain is 42 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. 2.2.13 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/PA10), USART3 (PC10/PC11 or PB10/PB11), CAN2 (PB5/PB13), USB OTG FS in Device mode (PA11/PA12) through DFU (device firmware upgrade). 2.2.14 Power supply schemes • VDD = 1.8 to 3.6 V: external power supply for I/Os and the internal regulator (when enabled), provided externally through VDD pins. • VSSA, VDDA = 1.8 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. Refer to Figure 21: Power supply scheme for more details. Note: VDD/VDDA minimum value of 1.7 V is obtained when the device operates in reduced temperature range, and with the use of an external power supply supervisor (refer to Section : Internal reset OFF). Refer to Table 2 in order to identify the packages supporting this option. 2.2.15 Power supply supervisor Internal reset ON On packages embedding the PDR_ON pin, the power supply supervisor is enabled by holding PDR_ON high. On all 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 threshold levels, 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. DocID022152 Rev 4 23/185 Description STM32F405xx, STM32F407xx 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. 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 with the PDR_ON pin. An external power supply supervisor should monitor VDD and should maintain the device in reset mode as long as VDD is below a specified threshold. PDR_ON should be connected to this external power supply supervisor. Refer to Figure 7: Power supply supervisor interconnection with internal reset OFF. Figure 7. Power supply supervisor interconnection with internal reset OFF VDD External VDD power supply supervisor Ext. reset controller active when VDD < 1.7 V or 1.8 V (1) PDR_ON NRST Application reset signal (optional) VDD MS31383V3 1. PDR = 1.7 V for reduce temperature range; PDR = 1.8 V for all temperature range. The VDD specified threshold, below which the device must be maintained under reset, is 1.8 V (see Figure 7). This supply voltage can drop to 1.7 V when the device operates in the 0 to 70 °C temperature range. 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 more supported: • The integrated power-on reset (POR) / power-down reset (PDR) circuitry is disabled • The brownout reset (BOR) circuitry is disabled • The embedded programmable voltage detector (PVD) is disabled • VBAT functionality is no more available and VBAT pin should be connected to VDD All packages, except for the LQFP64 and LQFP100, allow to disable the internal reset through the PDR_ON signal. 24/185 DocID022152 Rev 4 STM32F405xx, STM32F407xx Description Figure 8.

On all other packages, the regulator is always enabled. There are three power modes configured by software when 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. Refer to Table 14: General operating conditions. • 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) DocID022152 Rev 4 25/185 Description STM32F405xx, STM32F407xx Two external ceramic capacitors should be connected on VCAP_1 & VCAP_2 pin. Refer to Figure 21: Power supply scheme and Figure 16: VCAP_1/VCAP_2 operating conditions. All packages have regulator ON feature. 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 manage internally, the external voltage value must be aligned with the targetted maximum frequency. Refer to Table 14: General operating conditions. The two 2.2 µF ceramic capacitors should be replaced by two 100 nF decoupling capacitors. Refer to Figure 21: 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. Figure 9.

The minimum value of V12 depends on the maximum frequency targeted in the application (see Table 14: General operating conditions). Figure 10.

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 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 28/185 DocID022152 Rev 4 STM32F405xx, STM32F407xx Description 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 4-Kbyte backup SRAM is an EEPROM-like memory area. It can be used to store data which need to be retained in VBAT and standby mode. This memory area is disabled by default to minimize power consumption (see Section 2.2.19: Low-power modes). It can be enabled by software. 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 2.2.19: Low-power modes). Additional 32-bit registers contain the programmable alarm subseconds, seconds, minutes, hours, day, and date. Like backup SRAM, 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. 2.2.19 Low-power modes The STM32F405xx and STM32F407xx 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 V12 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, the USB OTG FS/HS wakeup or the Ethernet wakeup). • Standby mode The Standby mode is used to achieve the lowest power consumption. The internal voltage regulator is switched off so that the entire V12 domain is powered off. The PLL, the HSI RC and the HSE crystal oscillators are also switched off. After entering DocID022152 Rev 4 29/185 Description STM32F405xx, STM32F407xx 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 edge on the WKUP pin, 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 V12 domain is controlled by an external power. 2.2.20 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. 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 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. 2.2.21 Timers and watchdogs The STM32F405xx and STM32F407xx devices include two advanced-control timers, eight general-purpose timers, two basic timers and two watchdog timers. All timer counters can be frozen in debug mode. Table 4 compares the features of the advanced-control, general-purpose and basic timers. Table 4.

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. TIM1 and TIM8 support independent DMA request generation. DocID022152 Rev 4 31/185 Description STM32F405xx, STM32F407xx General-purpose timers (TIMx) There are ten synchronizable general-purpose timers embedded in the STM32F40x devices (see Table 4 for differences). • TIM2, TIM3, TIM4, TIM5 The STM32F40x include 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 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. Basic timers TIM6 and TIM7 These timers are mainly used for DAC trigger and waveform generation. They can also be used as a generic 16-bit time base. TIM6 and TIM7 support independent DMA request generation. 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. 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. 32/185 DocID022152 Rev 4 STM32F405xx, STM32F407xx Description SysTick timer This timer is dedicated to real-time operating systems, but could also be used as a standard downcounter. It features: 2.2.22 • 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-mode (up to 100 kHz) and Fast-mode (up to 400 kHz) . They 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. 2.2.23 Universal synchronous/asynchronous receiver transmitters (USART) The STM32F405xx and STM32F407xx embed four universal synchronous/asynchronous receiver transmitters (USART1, USART2, USART3 and USART6) and two universal asynchronous receiver transmitters (UART4 and UART5). These six 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 10.5 Mbit/s. The other available interfaces communicate at up to 5.25 Mbit/s. USART1, USART2, USART3 and USART6 also provide hardware management of the CTS and RTS signals, Smart Card mode (ISO 7816 compliant) and SPI-like communication capability. All interfaces can be served by the DMA controller. DocID022152 Rev 4 33/185 Description STM32F405xx, STM32F407xx Table 5.

SPI1 can communicate at up to 42 Mbits/s, SPI2 and SPI3 can communicate at up to 21 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. 2.2.25 Inter-integrated sound (I2S) Two standard I2S interfaces (multiplexed with SPI2 and SPI3) are available. They can be operated in master or slave mode, in full duplex and half-duplex 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. 2.2.26 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, while using USB peripherals. 34/185 DocID022152 Rev 4 STM32F405xx, STM32F407xx Description The PLLI2S configuration can be modified to manage an I2S sample rate change without disabling the main PLL (PLL) used for CPU, USB and Ethernet 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 flow with an external PLL (or Codec output). 2.2.27 Secure digital input/output interface (SDIO) An SD/SDIO/MMC 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 48 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, this interface is fully compliant with the CE-ATA digital protocol Rev1.1. 2.2.28 Ethernet MAC interface with dedicated DMA and IEEE 1588 support Peripheral available only on the STM32F407xx devices. The STM32F407xx devices provide an IEEE-802.3-2002-compliant media access controller (MAC) for ethernet LAN communications through an industry-standard mediumindependent interface (MII) or a reduced medium-independent interface (RMII). The STM32F407xx requires an external physical interface device (PHY) to connect to the physical LAN bus (twisted-pair, fiber, etc.). the PHY is connected to the STM32F407xx MII port using 17 signals for MII or 9 signals for RMII, and can be clocked using the 25 MHz (MII) from the STM32F407xx. The STM32F407xx includes the following features: • Supports 10 and 100 Mbit/s rates • Dedicated DMA controller allowing high-speed transfers between the dedicated SRAM and the descriptors (see the STM32F40x reference manual for details) • Tagged MAC frame support (VLAN support) • Half-duplex (CSMA/CD) and full-duplex operation • MAC control sublayer (control frames) support • 32-bit CRC generation and removal • Several address filtering modes for physical and multicast address (multicast and group addresses) • 32-bit status code for each transmitted or received frame • Internal FIFOs to buffer transmit and receive frames. The transmit FIFO and the receive FIFO are both 2 Kbytes. • Supports hardware PTP (precision time protocol) in accordance with IEEE 1588 2008 (PTP V2) with the time stamp comparator connected to the TIM2 input • Triggers interrupt when system time becomes greater than target time DocID022152 Rev 4 35/185 Description 2.2.29 STM32F405xx, STM32F407xx Controller area network (bxCAN) The two CANs are compliant with the 2.0A and B (active) specifications with a bitrate up to 1 Mbit/s. They can receive and transmit standard frames with 11-bit identifiers as well as extended frames with 29-bit identifiers. Each 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 for each CAN. 2.2.30 Universal serial bus on-the-go full-speed (OTG_FS) The STM32F405xx and STM32F407xx 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: 2.2.31 • 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 Universal serial bus on-the-go high-speed (OTG_HS) The STM32F405xx and STM32F407xx devices embed a USB OTG high-speed (up to 480 Mb/s) device/host/OTG peripheral. The USB OTG HS supports both full-speed and high-speed operations. It integrates the transceivers for full-speed operation (12 MB/s) and features a UTMI low-pin interface (ULPI) for high-speed operation (480 MB/s). When using the USB OTG HS in HS mode, an external PHY device connected to the ULPI is required. The USB OTG HS 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: 36/185 • Combined Rx and Tx FIFO size of 1 Kbit × 35 with dynamic FIFO sizing • Supports the session request protocol (SRP) and host negotiation protocol (HNP) • 6 bidirectional endpoints • 12 host channels with periodic OUT support • Internal FS OTG PHY support • External HS or HS OTG operation supporting ULPI in SDR mode. The OTG PHY is connected to the microcontroller ULPI port through 12 signals. It can be clocked using the 60 MHz output. • Internal USB DMA • 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 DocID022152 Rev 4 STM32F405xx, STM32F407xx 2.2.32 Description Digital camera interface (DCMI) The camera interface is not available in STM32F405xx devices. STM32F407xx products embed a camera interface that can connect with camera modules and CMOS sensors through an 8-bit to 14-bit parallel interface, to receive video data. The camera interface can sustain a data transfer rate up to 54 Mbyte/s at 54 MHz. It features: 2.2.33 • Programmable polarity for the input pixel clock and synchronization signals • Parallel data communication can be 8-, 10-, 12- or 14-bit • Supports 8-bit progressive video monochrome or raw bayer format, YCbCr 4:2:2 progressive video, RGB 565 progressive video or compressed data (like JPEG) • Supports continuous mode or snapshot (a single frame) mode • Capability to automatically crop the image Random number generator (RNG) All STM32F405xx and STM32F407xx products embed an RNG that delivers 32-bit random numbers generated by an integrated analog circuit. 2.2.34 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 84 MHz. 2.2.35 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 scan mode, 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. 2.2.36 Temperature sensor The temperature sensor has to generate a voltage that varies linearly with temperature. The conversion range is between 1.8 V and 3.6 V. The temperature sensor is internally DocID022152 Rev 4 37/185 Description STM32F405xx, STM32F407xx connected to the ADC1_IN16 input channel which is used to convert the sensor output voltage into a digital value. 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. 2.2.37 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. 2.2.38 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. 2.2.39 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 STM32F40x through a small number of ETM pins to an external hardware trace port analyser (TPA) device. The TPA is connected to a host computer using USB, Ethernet, or any other high-speed channel. 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.

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: - 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 STM32F4xx reference manual, available from the STMicroelectronics website: www.st.com. 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 UFBGA176 or WLCSP90 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). Table 8.

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 47: I/O static characteristics. For the output pins, any external pull-down or external load must also be considered to estimate the current consumption. Additional I/O current consumption is due to I/Os configured as inputs if an intermediate voltage level is externally applied. This current consumption is caused by the input Schmitt trigger circuits used to discriminate the input value. Unless this specific configuration is required by the application, this supply current consumption can be avoided by configuring these I/Os in analog mode. This is notably the case of ADC 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 measured previously (see Table 27: 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 90/185 DocID022152 Rev 4 STM32F405xx, STM32F407xx Electrical characteristics 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.

Guaranteed by design, not tested in production. 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 ) ] = 250 102/185 DocID022152 Rev 4 STM32F405xx, STM32F407xx Electrical characteristics 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 15 – 1 ) × 240 ) = 2.002%(peak) Figure 35 and Figure 36 show the main PLL output clock waveforms in center spread and down spread modes, where: F0 is fPLL_OUT nominal.

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: 106/185 • 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. DocID022152 Rev 4 STM32F405xx, STM32F407xx Electrical characteristics A device reset allows normal operations to be resumed.

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). Electromagnetic Interference (EMI) The electromagnetic field emitted by the device are monitored while a simple application, executing EEMBC? code, is running. This emission test is compliant with SAE IEC61967-2 standard which specifies the test board and the pin loading.

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. Table 44.

Static latchup Two complementary static tests are required on six parts to assess the latchup performance: • A supply overvoltage is applied to each power supply pin • A current injection is applied to each input, output and configurable I/O pin These tests are compliant with EIA/JESD 78A IC latchup standard. 108/185 Unit DocID022152 Rev 4 STM32F405xx, STM32F407xx Electrical characteristics Table 45.

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 susceptibilty 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 uA/+0 uA 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 46. Table 46.

Pull-up and pull-down resistors are designed with a true resistance in series with a switchable PMOS/NMOS. This MOS/NMOS contribution to the series resistance is minimum (~10% order). 6. Guaranteed by design, not tested in production. All I/Os are CMOS and TTL compliant (no software configuration required). Their characteristics cover more than the strict CMOS-technology or TTL parameters. Output driving current The GPIOs (general purpose input/outputs) can sink or source up to ±8 mA, and sink or source up to ±20 mA (with a relaxed VOL/VOH) except PC13, PC14 and PC15 which can sink or source up to ±3mA. When using the PC13 to PC15 GPIOs in output mode, the speed should not exceed 2 MHz with a maximum load of 30 pF. 110/185 DocID022152 Rev 4 STM32F405xx, STM32F407xx Electrical characteristics In the user application, the number of I/O pins which can drive current must be limited to respect the absolute maximum rating specified in Section 5.2. In particular: • The sum of the currents sourced by all the I/Os on VDD, plus the maximum Run consumption of the MCU sourced on VDD, cannot exceed the absolute maximum rating IVDD (see Table 12). • The sum of the currents sunk by all the I/Os on VSS plus the maximum Run consumption of the MCU sunk on VSS cannot exceed the absolute maximum rating IVSS (see Table 12).

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.
