of the stm32f4 family. they are fully pin- to-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 stm32f 407xx 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

is a memory accelera tor which is optimized for stm32 industry- standard 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 fo r applications where some critic al or certified code has to be protected against the misbehavior of other tasks. it is usually managed by an rtos (real- time operating system). if a program accesses a memory location that is prohibited by the mpu, the rtos can detect it and take action. in an rtos environment, the kernel can dynamically update the mpu area setting, based on the process to be executed. the mpu is optional and can be bypassed for applications that do not need it. stm32f405xx, stm32f407xx description doc id 022152 rev 2 19/167 2.2.4 embedded flash memory the stm32f40x devices embed a flash memory of 256 kbytes, 512 kbytes, 768 kbytes or 1 mbytes available for storing programs and data. 2.2.5 crc (cyclic redundanc y 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 includin g 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 cp u. its content is protected against possible unwanted write accesses, and is retained in standby or v bat 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. description stm32f405xx, stm32f407xx 20/167 doc id 022152 rev 2 figure 6. multi-ahb matrix 2.2.8 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 tr ansfers. they feature dedicate d 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. ! 2 - # o r t e x - ' 0 $ - !

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 cost- effective graphic applications using lcd modules with embedded controllers or high performance solutions using external controllers with dedicated acceleration. 2.2.10 nested vectored inte rrupt controller (nvic) the stm32f405xx and stm32f407xx embed a nested vectored interrupt controller able to manage 16 priority levels, and handle up to 87 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 interr upt/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 description stm32f405xx, stm32f407xx 22/167 doc id 022152 rev 2 pulse width shorter than the internal apb2 cloc k period. up to 140 gp ios 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-trim med to offer 1% accuracy over the full temperature range. the applicat ion 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 clock entry is available when necessary (for exam ple if an indirectly us ed 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 168 mhz while the maximum frequenc y 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 i 2 s 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/pc 11 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 v dd = 1.8 to 3.6 v: external power supply for i/os and the internal regulator (when enabled), provided externally through v dd pins. v ssa , v dda = 1.8 to 3.6 v: external analog power supplies for adc, dac, reset blocks, rcs and pll. v dda and v ssa must be connected to v dd and v ss , respectively. v bat = 1.65 to 3.6 v: power supply for rtc, external clock 32 khz oscillator and backup registers (through power switch) when v dd is not present. refer to figure 18: power supply scheme for more details. note: v dd /v dda minimum value of 1.7 v is obtained when the device operates in the 0 to 70 c temperature range and an inverted reset signal is applied to pdr_on. stm32f405xx, stm32f407xx description doc id 022152 rev 2 23/167 2.2.15 power supply supervisor the 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) circuitr y. at power-on, bor is always active, and ensures proper operation starting from 1.8 v. after the 1.8 v bor 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 v dd is below a specified threshold, v por/pdr or v bor , without the need for an external reset circuit. the device also features an embedded programmable voltage detector (pvd) that monitors the v dd /v dda power supply and compares it to the v pvd threshold. an interrupt can be generated when v dd /v dda drops below the v pvd threshold and/or when v dd /v dda is higher than the v pvd 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. all packages, except for the lqfp64 and lqfp100, have an internal reset controlled through the pdr_on signal. 2.2.16 voltage regulator the regulator has eight operating modes: regulator on/internal reset on ? main regulator mode (mr) ? low power regulator (lpr) ? power-down regulator on/internal reset off ? main regulator mode (mr) ? low power regulator (lpr) ? power-down regulator off/internal reset on regulator off/internal reset off regulator on regulator on/internal reset on the regulator on/internal reset on mode is always enabled on lqfp64 and lqfp100 package. on lqfp144 package, this mode is activated by setting pdr_on to v dd . on ufbga176 package, the internal regulator must be activated by connecting bypass_reg to v ss, and pdr_on to v dd . on lqfp176 packages, the internal reset must be activated by connecting pdr_on to v dd . description stm32f405xx, stm32f407xx 24/167 doc id 022152 rev 2 v dd minimum value is 1.8 v. v dd /v dda minimum value of 1.7 v is obtained when the device operates in the 0 to 70 c temperature range and pdr is disabled. there are three low-power modes: ? mr is used in the nominal regulation mode (run) ? lpr is used in the stop modes ? power-down is used in standby mode: the regulator output is in high impedance: the kernel circuitry is powered down, indu cing zero consumption (but the contents of the registers and sram are lost). regulator on/internal reset off the regulator on with internal reset off mode is not available on lqfp64 and lqfp100 packages. on lqfp144, and lqfp176 packages, the internal reset is controlled by applying an inverted reset signal to pdr_on pin. on ufbga176 package, the internal regulator must be activated by connecting bypass_reg to v ss . on lqfp176 packages, the internal reset must be activated by applying an inverted reset signal to pdr_on pin. the nrst pin should be controlled by an external reset controller to keep the device under reset when v dd is below 1.8 v (see figure 7 ).

regulator off/internal reset on mode allows to supply externally a 1.2 v voltage source through v cap_1 and v cap_2 pins, in addition to v dd . the following conditions must be respected: ?v dd should always be higher than v cap_1 and v cap_2 to avoid current injection between power domains. ? if the time for v cap_1 and v cap_2 to reach 1.08 v is faster than the time for v dd to reach 1.8 v (v dd /v dda minimum value of 1.7 v is obtained when the device operates in the 0 to 70 c temperature range and pdr is disabled), then pa0 should be connected to the nrst pin (see figure 8 ). otherwise, pa0 should be asserted low externally during por until v dd reaches 1.8 v (see figure 9 ). ?if v cap_1 and v cap_2 go below 1.08 v and v dd is higher than 1.7 v, then a reset must be asserted on pa0 pin. in regulator off/internal reset on mode, pa0 cannot be used as a gpio pin since it allows to reset the part of the 1.2 v logic which is not reset by the nrst pin, when the internal voltage regulator in off. regulator off/internal reset off this mode is available only on ufbga package. it is activated by setting bypass_reg pin to v dd and by applying an inverted reset signal to pdr_on, and allows to supply externally a 1.2 v voltage source through v cap_1 and v cap_2 pins, in addition to v dd . the following conditions must be respected: ?v dd should always be higher than v cap_1 and v cap_2 to avoid current injection between power domains. ? pa0 should be kept low to cover both conditions: until v cap_1 and v cap_2 reach 1.08 v and until v dd reaches 1.8 v (see figure 8 ). ? nrst should

(rtc), backup sram and backup registers the backup domain of the stm32f405xx and stm32f407xx includes: the real-time clock (rtc) 4 kbytes of backup sram 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 (binary-coded 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. 6 $ $ t i m e 6 a i c 0 $ 2 6 6 # ! 0 ? 6 # ! 0 ? 6 0 ! t i e d t o . 2 3 4 . 2 3 4 t i m e 6 $ $ t i m e 6 a i b 0 $ 2 6 6 # ! 0 ? 6 # ! 0 ? 6 0

internal low-power rc oscillator or the high -speed external clock divided by 128. the intern al 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 alar m 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 s 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 2.2.18: 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 v dd 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 2.2.18: 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 v dd supply when present or from the v bat pin. 2.2.18 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 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, 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 1.2 v domain is powered off. the pll, the hsi rc and the hse crystal oscillators are also switched off. after entering description stm32f405xx, stm32f407xx 28/167 doc id 022152 rev 2 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. note: when in standby mode, only an rtc alarm/event or an external reset can wake up the device provided v dd is supplied by an external battery. 2.2.19 v bat operation the v bat pin allows to power the device v bat domain from an external battery, an external supercapacitor, or from v dd when no external battery and an external supercapacitor are present. v bat operation is activated when v dd is not present. the v bat pin supplies the rtc, the backup registers and the backup sram. note: when the microcontroller is supplied from v bat , external interrupts and rtc alarm/events do not exit it from v bat operation. 2.2.20 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. ta bl e 3 compares the features of the advanced-control, general-purpose and basic timers. stm32f405xx, stm32f407xx description doc id 022152 rev 2 29/167 advanced-control timers (tim1, tim8) the advanced-control timers (tim1, tim8) can be seen as three-phase pwm generators multiplexed on 6 channels. they have complementary pwm outputs with programmable inserted dead times. they can also be considered as complete general-purpose timers. their 4 independent channels can be used for: input capture output compare pwm generation (edge- or center-aligned modes) one-pulse mode output if configured as standard 16-bit timers, they have the same features as the general-purpose timx timers. if configured as 16-bit pwm generators, they have full modulation capability (0- 100%). 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. table 3. timer feature comparison timer type timer counter

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 16-bit auto-reload up/downcounter and a 16-bit prescaler. they all feature 4 independent channels for input capture/output compare, pwm or one-pulse mode output. this gives up to 16 input capture/output compare/pwms on the largest packages. the tim2, tim3, tim4, tim5 general-purpose timers can work together, or with the other general-purpose timers and the advanced-control timers tim1 and tim8 via the timer link feature for synchr onization 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 downc ounter 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 interrup t capability and the counter can be frozen in debug mode. stm32f405xx, stm32f407xx description doc id 022152 rev 2 31/167 systick timer this timer is dedicated to real-time operating systems, but could also be used as a

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. 2.2.36 digital-to-anal og 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 v ref+ 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. 2.2.37 serial wire jt ag 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. stm32f405xx, stm32f407xx description doc id 022152 rev 2 37/167 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. 2.2.38 embedded trace macrocell? the arm embedded trace ma crocell provides a greater visib ility 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 analyzer (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. the embedded trace macrocell operates with third party debugger software tools. pinouts and pin description stm32f405xx, stm32f407xx 38/167 doc id 022152 rev 2 3 pinouts and pin description figure 10. stm32f40x

v bat current consumption (lse and rtc on/backup ram on) 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 44: 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 24: 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 - 3 6 0 1 2 3

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
