The STM32F215xx and STM32F217xx devices maintain a close compatibility with the whole STM32F10xxx family. All functional pins are pin-to-pin compatible. The STM32F215xx and STM32F217xx, 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 STM32F21x family remains simple as only a few pins are impacted. Figure 1 compatible board design between the STM32F21x and the STM32F10xxx family.

Doc ID 17050 Rev 4 15/158 Description 2.2.1 STM32F215xx, STM32F217xx ARM(R) CortexTM-M3 core with embedded Flash and SRAM The ARM Cortex-M3 processor is the latest generation of ARM processors for embedded systems. It was developed to provide a low-cost platform that meets the needs of MCU implementation, with a reduced pin count and low-power consumption, while delivering outstanding computational performance and an advanced response to interrupts. The ARM Cortex-M3 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. With its embedded ARM core, the STM32F215xx and STM32F217xx family is compatible with all ARM tools and software. Figure 1 shows the general block diagram of the STM32F21x family. 2.2.2 Memory protection unit The memory protection unit (MPU) is used to separate the processing of tasks from the data protection. The MPU can manage up to 8 protection areas that can all be further divided up into 8 subareas. The protection area sizes are between 32 bytes and the whole 4 gigabytes of addressable memory. The memory protection unit 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 (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. 2.2.3 Adaptive real-time memory accelerator (ART AcceleratorTM) The ART AcceleratorTM is a memory accelerator which is optimized for STM32 industrystandard ARM(R) CortexTM-M3 processors. It balances the inherent performance advantage of the ARM Cortex-M3 over Flash memory technologies, which normally requires the processor to wait for the Flash memory at higher operating frequencies. To release the processor full 150 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 120 MHz. 2.2.4 Embedded Flash memory The STM32F21x devices embed a 128-bit wide Flash memory of 128 Kbytes, 256 Kbytes, 512 Kbytes, 768 Kbytes or 1 Mbytes available for storing programs and data. The devices also feature 512 bytes of OTP memory that can be used to store critical user data such as Ethernet MAC addresses or cryptographic keys. 16/158 Doc ID 17050 Rev 4 STM32F215xx, STM32F217xx 2.2.5 Description 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 True random number generator (RNG) All STM32F2xxx products embed a true RNG that delivers 32-bit random numbers produced by an integrated analog circuit. 2.2.7 Embedded SRAM All STM32F21x products embed up to 128 Kbytes of system SRAM accessed (read/write) at CPU clock speed with 0 wait states, plus 4 Kbytes of backup SRAM. 2.2.8 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.

They share some centralized FIFOs for APB/AHB peripherals, support burst transfer and are designed to provide the maximum peripheral bandwidth (AHB/APB) and performance. 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: 2.2.10 SPI and I2S I2C USART and UART General-purpose, basic and advanced-control timers TIMx DAC SDIO Cryptographic acceleration Camera interface (DCMI) ADC. FSMC (flexible static memory controller) The FSMC is embedded in the STM32F215xx and STM32F217xx family. It has four Chip Select outputs supporting the following modes: PC Card/Compact Flash, SRAM, PSRAM, NOR Flash and NAND Flash. Functionality overview: Write FIFO Code execution from external memory except for NAND Flash and PC Card The targeted frequency, fCLK, is equal to HCLK/2, so external access is at 60 MHz when HCLK is at 120 MHz and external access is at 30 MHz when HCLK is at 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. 18/158 Doc ID 17050 Rev 4 STM32F215xx, STM32F217xx 2.2.11 Description Nested vectored interrupt controller (NVIC) The STM32F215xx and STM32F217xx embed a nested vectored interrupt controller able to handle up to 87 maskable interrupt channels (not including the 16 interrupt lines of the CortexTM-M3) and 16 priority levels. Closely coupled NVIC gives low-latency interrupt processing Interrupt entry vector table address passed directly to the core Closely coupled NVIC core interface 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. 2.2.12 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. 2.2.13 Clocks and startup System clock selection is performed on startup, however, the 16 MHz internal RC oscillator is selected as the default CPU clock on reset. An external 4-26 MHz clock can be selected, in which case it is monitored for failure. If failure is detected, the system automatically switches back to the internal RC oscillator. A software interrupt is generated if enabled. Similarly, full interrupt management of the PLL clock entry is available when necessary (for example if an indirectly used external oscillator fails). The advanced clock controller clocks the core and all peripherals using a single crystal or oscillator. In particular, the ethernet and USB OTG FS peripherals can be clocked by the system clock. Several prescalers and PLLs 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 120 MHz and the maximum frequency the high-speed APB domains is 60 MHz. The maximum allowed frequency of the low-speed APB domain is 30 MHz. In order to achieve audio class performance, a specific crystal can be used. In this case, the I2S master clock can generate all standard sampling frequencies from 8 kHz to 192 kHz. Doc ID 17050 Rev 4 19/158 Description 2.2.14 STM32F215xx, STM32F217xx 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/PB15), USB OTG FS in Device mode (PA11/PA12) through DFU (device firmware upgrade). 2.2.15 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 16: Power supply scheme for more details. 2.2.16 Power supply supervisor The device has an integrated power-on reset (POR) / power-down reset (PDR) circuitry coupled with a Brownout reset (BOR) circuitry. At power-on, BOR is always active, and ensures proper operation starting from 1.8 V. After the 1.8 V BOR threshold 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. 2.2.17 Voltage regulator The regulator has four operating modes: Regulator ON - Main regulator mode (MR) - Low power regulator (LPR) - Power-down Regulator OFF - Regulator OFF/internal reset ON Regulator ON The regulator ON modes are activated by default on LQFP packages. On UFBGA176 package, they are activated by connecting REGOFF to VSS. 20/158 Doc ID 17050 Rev 4 STM32F215xx, STM32F217xx Description VDD minimum value is 1.8 V. There are three regulator ON modes: MR is used in nominal regulation mode (Run) LPR is used in Stop mode Power-down is used in Standby mode: The regulator output is in high impedance: the kernel circuitry is powered down, inducing zero consumption (but the contents of the registers and SRAM are lost). Regulator OFF Regulator OFF/internal reset ON On UFBGA176 package, REGOFF must be connected to VDD. The regulator OFF/internal reset ON mode allows to supply externally a 1.2 V voltage source through VCAP_1 and VCAP_2 pins, in addition to VDD. The following conditions must be respected: - VDD should always be higher than VCAP_1 and VCAP_2 to avoid current injection between power domains. - If the time for VCAP_1 and VCAP_2 to reach 1.08 V is faster than the time for VDD to reach 1.8 V, then PA0 should be connected to the NRST pin (see Figure 6). Otherwise, PA0 should be asserted low externally during POR until VDD reaches 1.8 V (see Figure 7). In this 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. Figure 6.

ASSERTED EXTERNALLY .234 TIME 2.2.18 Real-time clock (RTC), backup SRAM and backup registers The backup domain of the STM32F215xx and STM32F217xx 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. 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 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 backup SRAM size is 4 Kbytes and can be enabled by software. When the backup RAM is enabled the power consumption in Standby or VBAT mode is slightly higher (see Section 2.2.19: Low-power modes). 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). The RTC, backup RAM and backup registers are supplied through a switch that takes power from either the VDD supply when present or the VBAT pin. 22/158 Doc ID 17050 Rev 4 STM32F215xx, STM32F217xx 2.2.19 Description Low-power modes The STM32F215xx and STM32F217xx 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 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: The RTC, the IWDG, and the corresponding clock sources are not stopped when the device enters the Stop or Standby mode. 2.2.20 VBAT operation The VBAT pin allows to power the device VBAT domain from an external battery or an external supercapacitor. VBAT operation is activated when VDD is not present. Note: When the microcontroller is supplied from VBAT, external interrupts and RTC alarm/events do not exit it from VBAT operation.

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%). 24/158 Doc ID 17050 Rev 4 STM32F215xx, STM32F217xx Description The TIM1 and TIM8 counters can be frozen in debug mode. Many of the advanced-control timer features are shared with those of the standard TIMx timers which have the same architecture. The advanced-control timer can therefore work together with the TIMx timers via the Timer Link feature for synchronization or event chaining. General-purpose timers (TIMx) There are ten synchronizable general-purpose timers embedded in the STM32F21x devices (see Table 3 for differences). TIM2, TIM3, TIM4, TIM5 The STM32F21x include 4 full-featured general-purpose timers. TIM2 and TIM5 are 32-bit timers, and TIM3 and TIM4 are 16-bit timers. 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 synchronization or event chaining. The counters of TIM2, TIM3, TIM4, TIM5 can be frozen in debug mode. 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. TIM10, TIM11 and TIM9 These timers are based on a 16-bit auto-reload upcounter and a 16-bit prescaler. TIM10 and TIM11 feature one independent channel, whereas TIM9 has two independent channels for input capture/output compare, PWM or one-pulse mode output. They can be synchronized with the TIM2, TIM3, TIM4, TIM5 full-featured general-purpose timers. They can also be used as simple time bases. TIM12, TIM13 and TIM14 These timers are based on a 16-bit auto-reload upcounter and a 16-bit prescaler. TIM13 and TIM14 feature one independent channel, whereas TIM12 has two independent channels for input capture/output compare, PWM or one-pulse mode output. They can be synchronized with the TIM2, TIM3, TIM4, TIM5 full-featured general-purpose timers. They can also be used as simple time bases. 2.2.22 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. Doc ID 17050 Rev 4 25/158 Description 2.2.23 STM32F215xx, STM32F217xx 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. The counter can be frozen in debug mode. 2.2.24 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. 2.2.25 SysTick timer This timer is dedicated to real-time operating systems, but could also be used as a standard downcounter. It features: 2.2.26 A 24-bit downcounter Autoreload capability Maskable system interrupt generation when the counter reaches 0 Programmable clock source IC bus Up to three IC bus interfaces can operate in multimaster and slave modes. They can support the Standard- and Fast-modes. 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. 2.2.27 Universal synchronous/asynchronous receiver transmitters (UARTs/USARTs) The STM32F215xx and STM32F217xx 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 7.5 Mbit/s. The other available interfaces communicate at up to 3.75 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. 26/158 Doc ID 17050 Rev 4 STM32F215xx, STM32F217xx Table 4.

SPI1 can communicate at up to 30 Mbits/s, SPI2 and SPI3 can communicate at up to 15 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. 2.2.29 Inter-integrated sound (I2S) Two standard I2S interfaces (multiplexed with SPI2 and SPI3) are available. They can be operated in master or slave mode, and can be configured to operate with a 16-/32-bit resolution as input or output channels. 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. Doc ID 17050 Rev 4 27/158 Description 2.2.30 STM32F215xx, STM32F217xx 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 in 8-bit mode, 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. 2.2.31 Ethernet MAC interface with dedicated DMA and IEEE 1588 support Peripheral available only on the STM32F217xx devices. The STM32F217xx 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 STM32F217xx requires an external physical interface device (PHY) to connect to the physical LAN bus (twisted-pair, fiber, etc.). the PHY is connected to the STM32F217xx MII port using 17 signals for MII or 9 signals for RMII, and can be clocked using the 25 MHz (MII) or 50 MHz (RMII) output from the STM32F217xx. The STM32F217xx includes the following features: 28/158 Supports 10 and 100 Mbit/s rates Dedicated DMA controller allowing high-speed transfers between the dedicated SRAM and the descriptors (see the STM32F20x and STM32F21x 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, that is 4 Kbytes in total 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 Doc ID 17050 Rev 4 STM32F215xx, STM32F217xx 2.2.32 Description Controller area network (CAN) 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). The 256 bytes of SRAM which are allocated for each CAN are not shared with any other peripheral. 2.2.33 Universal serial bus on-the-go full-speed (OTG_FS) The STM32F215xx and STM32F217xx 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: 2.2.34 Combined Rx and Tx FIFO size of 320 x 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 Internal FS OTG PHY support External FS OTG PHY support through an I2C connection Universal serial bus on-the-go high-speed (OTG_HS) The STM32F215xx and STM32F217xx 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 Doc ID 17050 Rev 4 29/158 Description STM32F215xx, STM32F217xx 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: 2.2.35 Combined Rx and Tx FIFO size of 1024x 35 bits 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 FS OTG PHY support through an I2C connection 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 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. 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). 2.2.36 Digital camera interface (DCMI) The camera interface is not available in STM32F215xx devices. STM32F217xx 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 up to 27 Mbyte/s at 27 MHz or 48 Mbyte/s at 48 MHz. It features: 30/158 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 Doc ID 17050 Rev 4 STM32F215xx, STM32F217xx 2.2.37 Description Cryptographic acceleration The STM32F215xx and STM32F217xx devices embed a cryptographic accelerator. This cryprographic accelerator provides a set of hardware acceleration for the advanced cryptographic algorithms usually needed to provide confidentiality, authentication, data integrity and non repudiation when exchanging messages with a peer. These algorithms consists of: Encryption/Decryption - DES/TDES (data encryption standard/triple data encryption standard): ECB (electronic codebook) and CBC (cipher block chaining) chaining algorithms, 64-, 128- or 192-bit key - AES (advanced encryption standard): ECB, CBC and CTR (counter mode) chaining algorithms, 128, 192 or 256-bit key Universal hash 2.2.38 - SHA-1 (secure hash algorithm) - MD5 It also provides a true random number generator that deliver 32-bit random numbers produced by an integrated analog circuit. GPIOs (general-purpose inputs/outputs) 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 alternate function configuration can be locked if needed by following a specific sequence in order to avoid spurious writing to the I/Os registers. To provide fast I/O handling, the GPIOs are on the fast AHB1 bus with a clock up to 120 MHz that leads to a maximum I/O toggling speed of 60 MHz. 2.2.39 ADCs (analog-to-digital converters) 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. The events generated by the timers TIM1, TIM2, TIM3, TIM4, TIM5 and TIM8 can be internally connected to the ADC start trigger and injection trigger, respectively, to allow the application to synchronize A/D conversion and timers. Doc ID 17050 Rev 4 31/158 Description 2.2.40 STM32F215xx, STM32F217xx DAC (digital-to-analog converter) The two 12-bit buffered DAC channels can be used to convert two digital signals into two analog voltage signal outputs. The design structure is composed of integrated resistor strings and an amplifier in inverting configuration. 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. 2.2.41 Temperature sensor The temperature sensor has to generate a voltage that varies linearly with temperature. The conversion range is between 1.8 and 3.6 V. The temperature sensor is internally 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. 2.2.42 Serial wire JTAG debug port (SWJ-DP) The ARM SWJ-DP interface is embedded, and is a combined JTAG and serial wire debug port that enables either a serial wire debug or a JTAG probe to be connected to the target. The 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. 2.2.43 Embedded Trace MacrocellTM 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 STM32F21x 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. 32/158 Doc ID 17050 Rev 4 STM32F215xx, STM32F217xx Pinouts and pin description STM32F21x LQFP64 pinout 6$$? 633? 0" 0" "//4 0" 0" 0" 0" 0" 0$ 0# 0# 0# 0! 0!

STM32F215xx, STM32F217xx Main function(3) (after reset) Alternate functions PI7 TIM8_CH3 / DCMI_D7 I/O FT Other functions 1. I = input, O = output, S = supply, HiZ = high impedance. 2. FT = 5 V tolerant; TT = 3.6 V tolerant. 3. Function availability depends on the chosen device. 4. 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 and these I/Os must not be used as a current source (e.g. to drive an LED). 5. 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 STM32F20x and STM32F21x reference manual, available from the STMicroelectronics website: www.st.com. 6. FT = 5 V tolerant except when in analog mode or oscillator mode (for PC14, PC15, PH0 and PH1). 7. If the device is delivered in an UFBGA176 package and if the REGOFF pin is set to VDD (Regulator OFF), then PA0 is used as an internal Reset (active low). 8. FSMC_NL pin is also named FSMC_NADV on memory devices. 9. RFU means "reserved for future use". This pin can be tied to VDD,VSS or left unconnected. 46/158 Doc ID 17050 Rev 4 Alternate function mapping AF0 AF1 AF2 AF3 AF4 AF5 AF6 AF7 AF8 USART1/2/3 UART4/5/ USART6 Port SYS TIM1/2 TIM3/4/5 PA0-WKUP TIM2_CH1 TIM2_ETR TIM 5_CH1 PA1 TIM2_CH2 TIM5_CH2 TIM8/9/10/11 I2C1/I2C2/I2C3 SPI1/SPI2/I2S2 SPI3/I2S3 TIM8_ETR ETH DCMI AF014 AF15 ETH_MII_CRS EVENTOUT ETH_MII _RX_CLK ETH_RMII _REF_CLK EVENTOUT ETH_MDIO EVENTOUT TIM5_CH3 TIM9_CH1 USART2_TX TIM5_CH4 TIM9_CH2 USART2_RX OTG_HS_ULPI_D0 ETH _MII_COL USART2_CK EVENTOUT OTG_HS_SOF PA5 TIM2_CH1 TIM2_ETR TIM8_CH1N SPI1_SCK PA6 TIM1_BKIN TIM3_CH1 TIM8_BKIN SPI1_MISO TIM13_CH1 PA7 TIM1_CH1N TIM3_CH2 TIM8_CH1N SPI1_MOSI TIM14_CH1 MCO1 AF13 UART4_TX TIM2_CH3 PA8 AF12 FSMC/SDIO/ OTG_FS UART4_RX TIM2_CH4 SPI3_NSS I2S3_WS AF11 USART2_RTS PA3 SPI1_NSS AF10 USART2_CTS PA2 PA4 AF9 CAN1/CAN2/ OTG_FS/ OTG_HS TIM12/13/14 DCMI_HSYNC EVENTOUT DCMI_PIXCK EVENTOUT OTG_HS_ULPI_CK EVENTOUT ETH_MII _RX_DV ETH_RMII _CRS_DV EVENTOUT Doc ID 17050 Rev 4 TIM1_CH1 I2C3_SCL USART1_CK PA9 TIM1_CH2 I2C3_SMBA USART1_TX PA10 TIM1_CH3 USART1_RX PA11 TIM1_CH4 USART1_CTS CAN1_RX OTG_FS_DM EVENTOUT PA12 TIM1_ETR USART1_RTS CAN1_TX OTG_FS_DP EVENTOUT PA13 JTMS-SWDIO PA14 JTCK-SWCLK PA15 JTDI Pinouts and pin description 47/158 Table 6.

Data based on characterization results, design simulation and/or technology characteristics are indicated in the table footnotes and are not tested in production. Based on characterization, the minimum and maximum values refer to sample tests and represent the mean value plus or minus three times the standard deviation (mean3). 5.1.2 Typical values Unless otherwise specified, typical data are based on TA = 25 C, VDD = 3.3 V (for the 1.8 V VDD 3.6 V voltage range). They are given only as design guidelines and are not tested. Typical ADC accuracy values are determined by characterization of a batch of samples from a standard diffusion lot over the full temperature range, where 95% of the devices have an error less than or equal to the value indicated (mean2). 5.1.3 Typical curves Unless otherwise specified, all typical curves are given only as design guidelines and are not tested. 5.1.4 Loading capacitor The loading conditions used for pin parameter measurement are shown in Figure 14. 5.1.5 Pin input voltage The input voltage measurement on a pin of the device is described in Figure 15.

The number of wait states can be reduced by reducing the CPU frequency (see Figure 18). 2. Thanks to the ART accelerator and the 128-bit Flash memory, the number of wait states given here does not impact the execution speed from Flash memory since the ART accelerator allows to achieve a performance equivalent to 0 wait state program execution. 3. The voltage range for OTG USB FS can drop down to 2.7 V. However it is degraded between 2.7 and 3 V. 58/158 Doc ID 17050 Rev 4 STM32F215xx, STM32F217xx Electrical characteristics Figure 18.

The current consumption is measured as described in Figure 17: Current consumption measurement scheme. All Run mode current consumption measurements given in this section are performed using CoreMark code. 62/158 Doc ID 17050 Rev 4 STM32F215xx, STM32F217xx Electrical characteristics Typical and maximum current consumption The MCU is placed under the following conditions: Table 15. At startup, all I/O pins are configured as analog inputs by firmware. All peripherals are disabled except if it is explicitly mentioned. The Flash memory access time is adjusted to fHCLK frequency (0 wait state from 0 to 30 MHz, 1 wait state from 30 to 60 MHz, 2 wait states from 60 to 90 MHz and 3 wait states from 90 to 120 MHz). When the peripherals are enabled HCLK is the system clock, fPCLK1 = fHCLK/4, and fPCLK2 = fHCLK/2, except is explicitly mentioned. The maximum values are obtained for VDD = 3.6 V and maximum ambient temperature (TA), and the typical values for TA= 25 C and VDD = 3.3 V unless otherwise specified.

This value is measured for a standard crystal resonator and it can vary significantly with the crystal manufacturer For CL1 and CL2, it is recommended to use high-quality external ceramic capacitors in the 5 pF to 25 pF range (typ.), designed for high-frequency applications, and selected to match the requirements of the crystal or resonator (see Figure 29). CL1 and CL2 are usually the same size. The crystal manufacturer typically specifies a load capacitance which is the series combination of CL1 and CL2. PCB and MCU pin capacitance must be included (10 pF can be used as a rough estimate of the combined pin and board capacitance) when sizing CL1 and CL2.

This value is measured for a standard crystal resonator and it can vary significantly with the crystal manufacturer Note: For CL1 and CL2 it is recommended to use high-quality external ceramic capacitors in the 5 pF to 15 pF range selected to match the requirements of the crystal or resonator (see Figure 30). CL1 and CL2, are usually the same size. The crystal manufacturer typically specifies a load capacitance which is the series combination of CL1 and CL2. Load capacitance CL has the following formula: CL = CL1 x CL2 / (CL1 + CL2) + Cstray where Cstray is the pin capacitance and board or trace PCB-related capacitance. Typically, it is between 2 pF and 7 pF. Caution: To avoid exceeding the maximum value of CL1 and CL2 (15 pF) it is strongly recommended to use a resonator with a load capacitance CL 7 pF. Never use a resonator with a load capacitance of 12.5 pF. Example: if you choose a resonator with a load capacitance of CL = 6 pF, and Cstray = 2 pF, then CL1 = CL2 = 8 pF. Figure 30.

Functional EMS (electromagnetic susceptibility) While a simple application is executed on the device (toggling 2 LEDs through I/O ports). the device is stressed by two electromagnetic events until a failure occurs. The failure is indicated by the LEDs: Electrostatic discharge (ESD) (positive and negative) is applied to all device pins until a functional disturbance occurs. This test is compliant with the IEC 61000-4-2 standard. FTB: A burst of fast transient voltage (positive and negative) is applied to VDD and VSS through a 100 pF capacitor, until a functional disturbance occurs. This test is compliant with the IEC 61000-4-4 standard. Doc ID 17050 Rev 4 85/158 Electrical characteristics STM32F215xx, STM32F217xx 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(R) code, is running. This emission test is compliant with SAE IEC61967-2 standard which specifies the test board and the pin loading. 86/158 Doc ID 17050 Rev 4 STM32F215xx, STM32F217xx Table 37.

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 x (n+1) supply pins). This test conforms to the JESD22-A114/C101 standard. Table 38.

Static latch-up Two complementary static tests are required on six parts to assess the latch-up 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 latch-up standard.

Electrical sensitivities Symbol LU 5.3.15 STM32F215xx, STM32F217xx Parameter Static latch-up class Conditions Class TA = +105 C conforming to JESD78A II level A I/O current injection characteristics As a general rule, current injection to the I/O pins, due to external voltage below VSS or above VDD (for standard, 3 V-capable I/O pins) should be avoided during normal product operation. However, in order to give an indication of the robustness of the microcontroller in cases when abnormal injection accidentally happens, susceptibility tests are performed on a sample basis during device characterization. Functional 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 spec current injection on adjacent pins or other functional failure (for example reset, oscillator frequency deviation). The test results are given in Table 40. Table 40.

Note: ADC accuracy vs. negative injection current: Injecting a negative current on any of the standard (non-robust) analog input pins should be avoided as this significantly reduces the accuracy of the conversion being performed on another analog input. It is recommended to add a Schottky diode (pin to ground) to standard analog pins which may potentially inject negative currents. Any positive injection current within the limits specified for IINJ(PIN) and IINJ(PIN) in Section 5.3.16 does not affect the ADC accuracy. Figure 48.

This is the maximum chip internal power. PI/O max represents the maximum power dissipation on output pins where: PI/O max = (VOL x IOL) + ((VDD - VOH) x IOH), taking into account the actual VOL / IOL and VOH / IOH of the I/Os at low and high level in the application.
