For information on the Cortex®-M4 core, please refer to the Cortex®-M4 programming manual (PM0214) available from www.st.com. DocID028094 Rev 6 11/143 31 Description 2 STM32F410x8/B Description The STM32F410X8/B devices are based on the high-performance Arm® Cortex® -M4 32-bit RISC core operating at a frequency of up to 100 MHz. Their 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 STM32F410X8/B belong 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 STM32F410X8/B incorporate high-speed embedded memories (up to 128 Kbytes of Flash memory, 32 Kbytes of SRAM), and an extensive range of enhanced I/Os and peripherals connected to two APB buses, one AHB bus and a 32-bit multi-AHB bus matrix. All devices offer one 12-bit ADC, one 12-bit DAC, a low-power RTC, three general-purpose 16-bit timers, one PWM timer for motor control, one general-purpose 32-bit timers and one 16-bit low-power timer. They also feature standard and advanced communication interfaces. • Up to three I2Cs • Three SPIs • Three I2Ss To achieve audio class accuracy, the I2S peripherals can be clocked via the internal PLL or via an external clock to allow synchronization. • Three USARTs. The STM32F410x8/B are offered in 5 packages ranging from 36 to 64 pins. The set of available peripherals depends on the selected package. The STM32F410x8/B operate in the – 40 to +125 °C temperature range from a 1.7 (PDR OFF) to 3.6 V power supply. A comprehensive set of power-saving mode allows the design of low-power applications. These features make the STM32F410x8/B microcontrollers suitable for a wide range of applications: 12/143 • Motor drive and application control • Medical equipment • Industrial applications: PLC, inverters, circuit breakers • Printers, and scanners • Alarm systems, video intercom, and HVAC • Home audio appliances • Mobile phone sensor hub DocID028094 Rev 6 STM32F410x8/B Description Table 2.

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 STM32F410x8/B devices are compatible with all Arm tools and software. Figure 2 shows the general block diagram of the STM32F410x8/B. 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 125 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 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 STM32F410x8/B BAM to allow the best power efficiency. 16/143 DocID028094 Rev 6 STM32F410x8/B 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 128 Kbytes of Flash memory available for storing programs and data, plus 512 bytes of OTP memory organized in 16 blocks which can be independently locked. 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. 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 32 Kbytes of system SRAM which can be accessed (read/write) at CPU clock speed with 0 wait states DocID028094 Rev 6 17/143 31 Functional overview 3.8 STM32F410x8/B 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.

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: 18/143 • SPI and I2S • I2C • USART • General-purpose, basic and advanced-control timers TIMx • ADC • DAC. DocID028094 Rev 6 STM32F410x8/B 3.10 Functional overview 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. • 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. 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 50 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 AHB bus, the high-speed APB (APB2) and the low-speed APB (APB1) domains. The maximum frequency of the AHB bus and highspeed APB domains is 100 MHz. The maximum allowed frequency of the low-speed APB domain is 50 MHz. DocID028094 Rev 6 19/143 31 Functional overview 3.13 STM32F410x8/B 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 bootloader is located in system memory. It is used to reprogram the Flash memory by using the interfaces described in Table 3. Refer to Table 9: STM32F410x8/B pin definitions) for the GPIOs available on the selected package.

Requires the use of an external power supply supervisor connected to the VDD and PDR_ON 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. DocID028094 Rev 6 STM32F410x8/B Functional overview 3.15 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 on WLCSP36 package only. 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 4: Power supply supervisor interconnection with internal reset OFF. Figure 4.

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 three operating modes: – Main regulator mode (MR) – Low power regulator (LPR) – Power-down The three power modes configured by software: • 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. An external ceramic capacitor should be connected to the VCAP_1 pin. 3.16.1 Internal power supply supervisor availability Table 4.

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. 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 DocID028094 Rev 6 23/143 31 Functional overview STM32F410x8/B and the HSE crystal oscillators are disabled. The voltage regulator can also be put either in normal or in low-power mode. The RTC and the low-power timer (LPTIM1) can remain active in Stop mode. They can consequently be used to wake up the device from this 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, LPTIM1, 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: 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. 3.20 Timers and watchdogs The devices embed one advanced-control timer, four general purpose timers, one low power timer, two watchdog timers and one SysTick timer. All timer counters can be frozen in debug mode. Table 5 compares the features of the advanced-control and general-purpose timers. 24/143 DocID028094 Rev 6 STM32F410x8/B Functional overview Table 5.

It has complementary PWM outputs with programmable inserted dead times. It can also be considered as a complete general-purpose timer. Its 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, 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 (TIM5, TIM9 and TIM11) There are three synchronizable general-purpose timers embedded in the STM32F410x8/B (see Table 5 for differences). • TIM5 The STM32F410x8/B devices includes a full-featured general-purpose timer, TIM5. TIM5 timer is based on a 32-bit auto-reload up/downcounter and a 16-bit prescaler. It features four independent channels for input capture/output compare, PWM or onepulse mode output. TIM5 can operate in conjunction with the other general-purpose timers and TIM1 advanced-control timer via the Timer Link feature for synchronization or event chaining. TIM5 general-purpose timer can be used to generate PWM output. All TIM5 channels 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 and TIM11 These timers are based on a 16-bit auto-reload upcounter and a 16-bit prescaler. TIM11 features 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 TIM5 full-featured general-purpose timer or used as simple time bases. 3.20.3 Basic timer (TIM6) This timer is mainly used for DAC triggering and waveform generation. It can also operate as generic 16-bit timers. TIM6 supports independent DMA request generation. 26/143 DocID028094 Rev 6 STM32F410x8/B 3.20.4 Functional overview Low-power timer (LPTIM1) The devices embed one low-power timer. This timer features an independent clock and runs in Stop mode if it is clocked by LSE, LSI or by an external clock. It is able to wake up the system from Stop mode. The low-power timer main features are the following: 3.20.5 • 16-bit up counter with 16-bit autoreload register • 16-bit compare register • Configurable output: pulse, PWM • Continuous/ one shot mode • Selectable software/hardware input trigger • Selectable clock source – Internal clock sources: LSE, LSI, HSI or APB1 clock – External clock source over LPTIM input (working even when no internal clock source is running and used by pulse-counter applications). • Programmable digital glitch filter • Encoder mode • Active in Stop mode. Independent watchdog The independent watchdog is based on a 12-bit downcounter and 8-bit prescaler. It is clocked from an independent 32 kHz internal RC and as it operates independently from the main clock, it can operate in Stop and Standby modes. It can be used either as a watchdog to reset the device when a problem occurs, or as a free-running timer for application timeout management. It is hardware- or software-configurable through the option bytes. 3.20.6 Window watchdog The window watchdog is based on a 7-bit downcounter that can be set as free-running. It can be used as a watchdog to reset the device when a problem occurs. It is clocked from the main clock. It has an early warning interrupt capability and the counter can be frozen in debug mode. 3.20.7 SysTick timer This timer is dedicated to real-time operating systems, but could also be used as a standard downcounter. It features: • A 24-bit downcounter • Autoreload capability • Maskable system interrupt generation when the counter reaches 0 • Programmable clock source. DocID028094 Rev 6 27/143 31 Functional overview 3.21 STM32F410x8/B Inter-integrated circuit interface (I2C) The devices feature up to three I2C bus interfaces which can operate in multimaster and slave modes: • One I2C interface supports the Standard mode (up to 100 kHz), Fast-mode (up to 400 kHz) modes and Fast-mode plus (up to 1 MHz). • Two I2C interfaces support the Standard mode (up to 100 KHz) and the Fast mode (up to 400 KHz). Their frequency can be increased up to 1 MHz. For more details on the complete solution, refer to the nearest STMicroelectronics sales office. All I2C interfaces features 7/10-bit addressing mode and 7-bit addressing mode (as slave) and embed a hardware CRC generation/verification. 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 6). Table 6. Comparison of I2C analog and digital filters Pulse width of suppressed spikes 3.22 Analog filter Digital filter ≥ 50 ns Programmable length from 1 to 15 I2C peripheral clocks Universal synchronous/asynchronous receiver transmitters (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. USART1 and USART2 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. 28/143 DocID028094 Rev 6 STM32F410x8/B Functional overview Table 7.

Not available on WLCSP36 package. 2. Not available on UFQFPN48 package. 3.23 Serial peripheral interface (SPI) The devices feature three SPIs in slave and master modes in full-duplex and simplex communication modes. SPI1 and SPI5 can communicate at up to 50 Mbit/s, SPI2 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) Three standard I2S interfaces (multiplexed with SPI1 to SPI5) are available. They can be operated in master or slave mode, in simplex communication modes and can be configured to operate with a 16-/32-bit resolution as an input or output channel. 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 Random number generator (RNG) All devices embed an RNG that delivers 32-bit random numbers generated by an integrated analog circuit. DocID028094 Rev 6 29/143 31 Functional overview 3.26 STM32F410x8/B 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. 3.27 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 or TIM5 timer. 3.28 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. 3.29 Digital-to-analog converter (DAC) One 12-bit buffered DAC channel can be used to convert a digital signal into an analog voltage signal output. The chosen design structure is composed of integrated resistor strings and an amplifier in inverting configuration. This digital interface supports the following features: 30/143 • 8-bit or 12-bit monotonic output • Buffer offset calibration (factory and user trimming) • Left or right data alignment in 12-bit mode • Synchronized update capability • Noise-wave generation DocID028094 Rev 6 STM32F410x8/B Functional overview • Triangular-wave generation • DMA capability for each channel • External triggers for conversion • Sample and hold low-power mode, with internal or external capacitor The DAC channel is triggered through TIM6 update output that is also connected to different DMA channels. 3.30 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. 3.31 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 STM32F410x8/B 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.

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.

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 60. 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.

It must be at least 4 MHz to achieve fast mode I2C frequencies, and a multiple of 10 MHz to reach the 400 kHz maximum I2C fast mode clock. 3. The device must internally provide a hold time of at least 300 ns for the SDA signal in order to bridge the undefined region of the falling edge of SCL.
