In the reference manual, the STM32F103x4 and STM32F103x6 are identified as low-density devices, the STM32F103x8 and STM32F103xB are referred to as medium-density devices, and the STM32F103xC, STM32F103xD and STM32F103xE are referred to as high-density devices. Low- and high-density devices are an extension of the STM32F103x8/B devices, they are specified in the STM32F103x4/6 and STM32F103xC/D/E datasheets, respectively. Lowdensity devices feature lower Flash memory and RAM capacities, less timers and peripherals. High-density devices have higher Flash memory and RAM capacities, and additional peripherals like SDIO, FSMC, I2S and DAC, while remaining fully compatible with the other members of the STM32F103xx family. The STM32F103x4, STM32F103x6, STM32F103xC, STM32F103xD and STM32F103xE are a drop-in replacement for STM32F103x8/B medium-density devices, allowing the user to try different memory densities and providing a greater degree of freedom during the development cycle. Moreover, the STM32F103xx performance line family is fully compatible with all existing STM32F101xx access line and STM32F102xx USB access line devices. Table 3.

Doc ID 15060 Rev 5 13/87 Description STM32F103x4, STM32F103x6 2.3 Overview 2.3.1 ARM(R) CortexTM-M3 core with embedded Flash and SRAM The ARM CortexTM-M3 processor is the latest generation of ARM processors for embedded systems. It has been 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 system response to interrupts. The ARM CortexTM-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. The STM32F103xx performance line family having an embedded ARM core, is therefore compatible with all ARM tools and software. Figure 1 shows the general block diagram of the device family. 2.3.2 Embedded Flash memory 16 or 32 Kbytes of embedded Flash is available for storing programs and data. 2.3.3 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 signature of the software during runtime, to be compared with a reference signature generated at linktime and stored at a given memory location. 2.3.4 Embedded SRAM Six or ten Kbytes of embedded SRAM accessed (read/write) at CPU clock speed with 0 wait states. 2.3.5 Nested vectored interrupt controller (NVIC) The STM32F103xx performance line embeds a nested vectored interrupt controller able to handle up to 43 maskable interrupt channels (not including the 16 interrupt lines of CortexTM-M3) and 16 priority levels. 14/87 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 for tail-chaining Processor state automatically saved Interrupt entry restored on interrupt exit with no instruction overhead Doc ID 15060 Rev 5 STM32F103x4, STM32F103x6 Description This hardware block provides flexible interrupt management features with minimal interrupt latency. 2.3.6 External interrupt/event controller (EXTI) The external interrupt/event controller consists of 19 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 51 GPIOs can be connected to the 16 external interrupt lines. 2.3.7 Clocks and startup System clock selection is performed on startup, however the internal RC 8 MHz oscillator is selected as default CPU clock on reset. An external 4-16 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 on failure of an indirectly used external crystal, resonator or oscillator). Several prescalers allow the configuration of the AHB frequency, the high-speed APB (APB2) and the low-speed APB (APB1) domains. The maximum frequency of the AHB and the high-speed APB domains is 72 MHz. The maximum allowed frequency of the low-speed APB domain is 36 MHz. See Figure 2 for details on the clock tree. 2.3.8 Boot modes At startup, boot pins are used to select one 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. For further details please refer to AN2606. 2.3.9 Power supply schemes VDD = 2.0 to 3.6 V: external power supply for I/Os and the internal regulator. Provided externally through VDD pins. VSSA, VDDA = 2.0 to 3.6 V: external analog power supplies for ADC, reset blocks, RCs and PLL (minimum voltage to be applied to VDDA is 2.4 V when the ADC is used). VDDA and VSSA must be connected to VDD and VSS, respectively. VBAT = 1.8 to 3.6 V: power supply for RTC, external clock 32 kHz oscillator and backup registers (through power switch) when VDD is not present. For more details on how to connect power pins, refer to Figure 11: Power supply scheme. 2.3.10 Power supply supervisor The device has an integrated power-on reset (POR)/power-down reset (PDR) circuitry. It is always active, and ensures proper operation starting from/down to 2 V. The device remains Doc ID 15060 Rev 5 15/87 Description STM32F103x4, STM32F103x6 in reset mode when VDD is below a specified threshold, VPOR/PDR, without the need for an external reset circuit. The device 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. Refer to Table 11: Embedded reset and power control block characteristics for the values of VPOR/PDR and VPVD. 2.3.11 Voltage regulator The regulator has three operation modes: main (MR), low power (LPR) and power down. MR is used in the nominal regulation mode (Run) LPR is used in the 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) This regulator is always enabled after reset. It is disabled in Standby mode, providing high impedance output. 2.3.12 Low-power modes The STM32F103xx performance line supports 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 content of SRAM and registers. All clocks in the 1.8 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 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 or the USB 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 1.8 V domain is powered off. The PLL, the HSI RC and the HSE crystal oscillators are also switched off. After entering Standby mode, SRAM and register contents are lost except for registers in the Backup domain and Standby circuitry. The device exits Standby mode when an external reset (NRST pin), an IWDG reset, a rising edge on the WKUP pin, or an RTC alarm occurs. Note: 16/87 The RTC, the IWDG, and the corresponding clock sources are not stopped by entering Stop or Standby mode. Doc ID 15060 Rev 5 STM32F103x4, STM32F103x6 2.3.13 Description DMA The flexible 7-channel general-purpose DMA is able to manage memory-to-memory, peripheral-to-memory and memory-to-peripheral transfers. The DMA controller supports circular buffer management avoiding the generation of interrupts when the controller reaches the end of the buffer. Each channel is connected to dedicated hardware DMA requests, with support for software trigger on each channel. Configuration is made by software and transfer sizes between source and destination are independent. The DMA can be used with the main peripherals: SPI, I2C, USART, general-purpose and advanced-control timers TIMx and ADC. 2.3.14 RTC (real-time clock) and backup registers The RTC and the backup registers are supplied through a switch that takes power either on VDD supply when present or through the VBAT pin. The backup registers are ten 16-bit registers used to store 20 bytes of user application data when VDD power is not present. The real-time clock provides a set of continuously running counters which can be used with suitable software to provide a clock calendar function, and provides an alarm interrupt and a periodic interrupt. 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-power RC has a typical frequency of 40 kHz. The RTC can be calibrated using an external 512 Hz output to compensate for any natural crystal deviation. The RTC features a 32-bit programmable counter for long-term measurement using the Compare register to generate an alarm. A 20-bit prescaler is used for the time base clock and is by default configured to generate a time base of 1 second from a clock at 32.768 kHz. 2.3.15 Timers and watchdogs The low-density STM32F101xx performance line devices include an advanced-control timer, two general-purpose timers, two watchdog timers and a SysTick timer. Table 4 compares the features of the advanced-control and general-purpose timers. Table 4.

It has complementary PWM outputs with programmable inserted dead-times. It can also be seen as a complete general-purpose timer. The 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 a general-purpose 16-bit timer, it has the same features as the TIMx timer. If configured as the 16-bit PWM generator, it has full modulation capability (0-100%). In debug mode, the advanced-control timer counter can be frozen and the PWM outputs disabled to turn off any power switch driven by these outputs. Many features are shared with those of the general-purpose TIM timers which have the same architecture. The advanced-control timer can therefore work together with the TIM timers via the Timer Link feature for synchronization or event chaining. General-purpose timers (TIMx) There are up to two synchronizable general-purpose timers embedded in the STM32F103xx performance line devices. These timers are based on a 16-bit auto-reload up/down counter, a 16-bit prescaler and feature 4 independent channels each for input capture/output compare, PWM or one-pulse mode output. This gives up to 12 input captures/output compares/PWMs on the largest packages. The general-purpose timers can work together with the advanced-control timer via the Timer Link feature for synchronization or event chaining. Their counter can be frozen in debug mode. Any of the general-purpose timers can be used to generate PWM outputs. They all have independent DMA request generation. These timers are capable of handling quadrature (incremental) encoder signals and the digital outputs from 1 to 3 hall-effect sensors. Independent watchdog The independent watchdog is based on a 12-bit downcounter and 8-bit prescaler. It is clocked from an independent 40 kHz internal RC and as it operates independently of 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. 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. 18/87 Doc ID 15060 Rev 5 STM32F103x4, STM32F103x6 Description SysTick timer This timer is dedicated for OS, but could also be used as a standard downcounter. It features: 2.3.16 A 24-bit downcounter Autoreload capability Maskable system interrupt generation when the counter reaches 0 Programmable clock source IC bus The IC bus interface can operate in multimaster and slave modes. It can support standard and fast modes. It supports dual slave addressing (7-bit only) and both 7/10-bit addressing in master mode. A hardware CRC generation/verification is embedded. It can be served by DMA and they support SM Bus 2.0/PM Bus. 2.3.17 Universal synchronous/asynchronous receiver transmitter (USART) One of the USART interfaces is able to communicate at speeds of up to 4.5 Mbit/s. The other available interface communicates at up to 2.25 Mbit/s. They provide hardware management of the CTS and RTS signals, IrDA SIR ENDEC support, are ISO 7816 compliant and have LIN Master/Slave capability. All USART interfaces can be served by the DMA controller. 2.3.18 Serial peripheral interface (SPI) The SPI interface is able to communicate up to 18 Mbits/s in slave and master modes in fullduplex and simplex communication modes. 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. The SPI interface can be served by the DMA controller. 2.3.19 Controller area network (CAN) The CAN is compliant with specifications 2.0A and B (active) with a bit rate up to 1 Mbit/s. It can receive and transmit standard frames with 11-bit identifiers as well as extended frames with 29-bit identifiers. It has three transmit mailboxes, two receive FIFOs with 3 stages and 14 scalable filter banks. 2.3.20 Universal serial bus (USB) The STM32F103xx performance line embeds a USB device peripheral compatible with the USB full-speed 12 Mbs. The USB interface implements a full-speed (12 Mbit/s) function interface. It has software-configurable endpoint setting and suspend/resume support. The dedicated 48 MHz clock is generated from the internal main PLL (the clock source must use a HSE crystal oscillator). Doc ID 15060 Rev 5 19/87 Description 2.3.21 STM32F103x4, STM32F103x6 GPIOs (general-purpose inputs/outputs) Each of the GPIO pins can be configured by software as output (push-pull or open-drain), as input (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-currentcapable except for analog inputs. The I/Os alternate function configuration can be locked if needed following a specific sequence in order to avoid spurious writing to the I/Os registers. I/Os on APB2 with up to 18 MHz toggling speed 2.3.22 ADC (analog-to-digital converter) Two 12-bit analog-to-digital converters are embedded into STM32F103xx performance line devices and each ADC shares up to 16 external channels, performing conversions in singleshot or scan modes. 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 Single shunt 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 general-purpose timers (TIMx) and the advanced-control timer (TIM1) can be internally connected to the ADC start trigger, injection trigger, and DMA trigger respectively, to allow the application to synchronize A/D conversion and timers. 2.3.23 Temperature sensor The temperature sensor has to generate a voltage that varies linearly with temperature. The conversion range is between 2 V < VDDA < 3.6 V. The temperature sensor is internally connected to the ADC12_IN16 input channel which is used to convert the sensor output voltage into a digital value. 2.3.24 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. 20/87 Doc ID 15060 Rev 5 STM32F103x4, STM32F103x6 Pinouts and pin description STM32F103xx performance line LQFP64 pinout VDD_3 VSS_3 PB9 PB8 BOOT0 PB7 PB6 PB5 PB4 PB3 PD2 PC12 PC11 PC10 PA15 PA14 Figure 3.

I = input, O = output, S = supply. 2. FT = 5 V tolerant. 3. Function availability depends on the chosen device. For devices having reduced peripheral counts, it is always the lower number of peripheral that is included. For example, if a device has only one SPI and two USARTs, they will be called SPI1 and USART1 & USART2, respectively. Refer to Table 2 on page 10. 4. If several peripherals share the same I/O pin, to avoid conflict between these alternate functions only one peripheral should be enabled at a time through the peripheral clock enable bit (in the corresponding RCC peripheral clock enable register). 5. PC13, PC14 and PC15 are supplied through the power switch. Since the switch only sinks a limited amount of current (3 mA), the use of GPIOs PC13 to PC15 in output mode is limited: the speed should not exceed 2 MHz with a maximum load of 30 pF and these IOs must not be used as a current source (e.g. to drive an LED). 6. Main function after the first backup domain power-up. Later on, it depends on the contents of the Backup registers even after reset (because these registers are not reset by the main reset). For details on how to manage these IOs, refer to the Battery backup domain and BKP register description sections in the STM32F10xxx reference manual, available from the STMicroelectronics website: www.st.com. 7. Unlike in the LQFP64 package, there is no PC3 in the TFBGA64 package. The VREF+ functionality is provided instead. 8. This alternate function can be remapped by software to some other port pins (if available on the used package). For more details, refer to the Alternate function I/O and debug configuration section in the STM32F10xxx reference manual, available from the STMicroelectronics website: www.st.com. 9. The pins number 2 and 3 in the VFQFPN36 package, 5 and 6 in the LQFP48 and LQFP64 packages and C1 and C2 in the TFBGA64 package are configured as OSC_IN/OSC_OUT after reset, however the functionality of PD0 and PD1 can be remapped by software on these pins. For more details, refer to the Alternate function I/O and debug configuration section in the STM32F10xxx reference manual.

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.

This value is measured for a standard crystal and it can vary significantly with the crystal manufacturer Note: For CL1 and CL2 it is recommended to use high-quality ceramic capacitors in the 5 pF to 15 pF range selected to match the requirements of the crystal or resonator. 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. 48/87 Doc ID 15060 Rev 5 STM32F103x4, STM32F103x6 Electrical characteristics Figure 22.

Functional EMS (electromagnetic susceptibility) While a simple application is executed on the device (toggling 2 LEDs through I/O ports). the device is stressed by two electromagnetic events until a failure occurs. The failure is indicated by the LEDs: Electrostatic discharge (ESD) (positive and negative) is applied to all device pins until a functional disturbance occurs. This test is compliant with the IEC 61000-4-2 standard. FTB: A Burst of Fast Transient voltage (positive and negative) is applied to VDD and VSS through a 100 pF capacitor, until a functional disturbance occurs. This test is compliant with the IEC 61000-4-4 standard. A device reset allows normal operations to be resumed. The test results are given in Table 30. They are based on the EMS levels and classes defined in application note AN1709. 52/87 Doc ID 15060 Rev 5 STM32F103x4, STM32F103x6 Table 30.

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 is executed (toggling 2 LEDs through the I/O ports). This emission test is compliant with IEC 61967-2 standard which specifies the test board and the pin loading. Table 31.

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 32.

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 34 Table 34.

A high Cparasitic value will downgrade conversion accuracy. To remedy this, fADC should be reduced. General PCB design guidelines Power supply decoupling should be performed as shown inFigure 36 or Figure 37, depending on whether VREF+ is connected to VDDA or not. The 10 nF capacitors should be ceramic (good quality). They should be placed them as close as possible to the chip. Figure 36.

The maximum chip-junction temperature, TJ max, in degrees Celsius, may be calculated using the following equation: TJ max = TA max + (PD max x JA) Where: TA max is the maximum ambient temperature in C, JA is the package junction-to-ambient thermal resistance, in C/W, PD max is the sum of PINT max and PI/O max (PD max = PINT max + PI/Omax), PINT max is the product of IDD and VDD, expressed in Watts. This is the maximum chip internal power. PI/O max represents the maximum power dissipation on output pins where: PI/O max = (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.

Doc ID 15060 Rev 5 81/87 Package characteristics 6.2.2 STM32F103x4, STM32F103x6 Selecting the product temperature range When ordering the microcontroller, the temperature range is specified in the ordering information scheme shown in Table 57: Ordering information scheme. Each temperature range suffix corresponds to a specific guaranteed ambient temperature at maximum dissipation and, to a specific maximum junction temperature. As applications do not commonly use the STM32F103xx at maximum dissipation, it is useful to calculate the exact power consumption and junction temperature to determine which temperature range will be best suited to the application. The following examples show how to calculate the temperature range needed for a given application. Example 1: High-performance application Assuming the following application conditions: Maximum ambient temperature TAmax = 82 C (measured according to JESD51-2), IDDmax = 50 mA, VDD = 3.5 V, maximum 20 I/Os used at the same time in output at low level with IOL = 8 mA, VOL= 0.4 V and maximum 8 I/Os used at the same time in output at low level with IOL = 20 mA, VOL= 1.3 V PINTmax = 50 mA x 3.5 V= 175 mW PIOmax = 20 x 8 mA x 0.4 V + 8 x 20 mA x 1.3 V = 272 mW This gives: PINTmax = 175 mW and PIOmax = 272 mW: PDmax = 175 + 272 = 447 mW Thus: PDmax = 447 mW Using the values obtained in Table 56 TJmax is calculated as follows: - For LQFP64, 45 C/W TJmax = 82 C + (45 C/W x 447 mW) = 82 C + 20.115 C = 102.115 C This is within the range of the suffix 6 version parts (-40 < TJ < 105 C). In this case, parts must be ordered at least with the temperature range suffix 6 (see Table 57: Ordering information scheme). Example 2: High-temperature application Using the same rules, it is possible to address applications that run at high ambient temperatures with a low dissipation, as long as junction temperature TJ remains within the specified range. Assuming the following application conditions: Maximum ambient temperature TAmax = 115 C (measured according to JESD51-2), IDDmax = 20 mA, VDD = 3.5 V, maximum 20 I/Os used at the same time in output at low level with IOL = 8 mA, VOL= 0.4 V PINTmax = 20 mA x 3.5 V= 70 mW PIOmax = 20 x 8 mA x 0.4 V = 64 mW This gives: PINTmax = 70 mW and PIOmax = 64 mW: PDmax = 70 + 64 = 134 mW Thus: PDmax = 134 mW 82/87 Doc ID 15060 Rev 5 STM32F103x4, STM32F103x6 Package characteristics Using the values obtained in Table 56 TJmax is calculated as follows: - For LQFP64, 45 C/W TJmax = 115 C + (45 C/W x 134 mW) = 115 C + 6.03 C = 121.03 C This is within the range of the suffix 7 version parts (-40 < TJ < 125 C). In this case, parts must be ordered at least with the temperature range suffix 7 (see Table 57: Ordering information scheme). Figure 48.
