Full compatibility throughout the family
The STM32F103xx is a complete family whose members are fully pin-to-pin, software and
feature compatible. In the reference manual, the STM32F103x6, STM32F103x8 and
STM32F103xB are referred to as Medium-density devices, while the STM32F103xC,
STM32F103xD and STM32F103xE are referred to as High-density devices. High-density
devices are an extension of the Medium-density STM32F103x6/8/B/C devices specified in

Description
Embedded Flash memory
Up to 512 Kbytes of embedded Flash is available for storing programs and data.
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.
Embedded SRAM
Up to 64 Kbytes of embedded SRAM accessed (read/write) at CPU clock speed with 0 wait
states.
FSMC (flexible static memory controller)
The FSMC is embedded in the STM32F103xC, STM32F103xD and STM32F103xE
performance line family. It has four Chip Select outputs supporting the following modes:
RAM, PSRAM, NOR and NAND.
Functionality overview:
●
The three FSMC interrupt lines are ORed in order to be connected to the NVIC
●
Write FIFO
●
Code execution from external memory except for
●
The targeted frequency is SYSCLK/2, so external access is at 36 MHz when the
system is at 72 MHz and external access is at 24 MHz when the system is at 48 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 highperformance solutions using external controllers with dedicated acceleration.

Nested vectored interrupt controller (NVIC)
The STM32F103xC, STM32F103xD and STM32F103xE performance line embeds a nested
vectored interrupt controller able to handle up to 60 maskable interrupt channels (not
including the 16 interrupt lines of Cortex™-M3) and 16 priority levels.

●
Interrupt entry restored on interrupt exit with no instruction overhead
This hardware block provides flexible interrupt management features with minimal interrupt
latency.
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 112 GPIOs can be connected
to the 16 external interrupt lines.
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 with
failure of an indirectly used external 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.
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.

Description
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.
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
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 power supply and compares it to the VPVD threshold. An interrupt can be generated
when VDD drops below the VPVD and/or when VDD 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.
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 modes.
●
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.
Low-power modes
The STM32F103xC, STM32F103xD and STM32F103xE 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
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.
13/118
Description
STM32F103xC, STM32F103xD, STM32F103xE
●
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:
The RTC, the IWDG, and the corresponding clock sources are not stopped by entering Stop
or Standby mode.
DMA
The flexible 12-channel general-purpose DMAs (7 channels for DMA1 and 5 channels for
DMA2) are able to manage memory-to-memory, peripheral-to-memory and memory-toperipheral transfers. The two DMA controllers support circular buffer management,
removing the need for user code intervention 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, basic
and advanced control timers TIMx, DAC, I2S, SDIO and ADC.
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 forty-two 16-bit
registers used to store 84 bytes of user application data. They are not reset by a system or
power reset, and they are not reset when the device wakes up from the Standby mode.
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-speed RC has a typical frequency of 40 kHz. The RTC can be calibrated using
an external 512 Hz output to compensate for any natural quartz 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.
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 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.

Description
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.
SysTick timer
This timer is dedicated to real-time operating systems, but could also be used as a standard
down counter. It features:
●
A 24-bit down counter
●
Autoreload capability
●
Maskable system interrupt generation when the counter reaches 0.
●
Programmable clock source
General-purpose timers (TIMx)
There are up to 4 synchronizable standard timers (TIM2, TIM3, TIM4 and TIM5) embedded
in the STM32F103xC, STM32F103xD and STM32F103xE 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 16 input captures / output compares / PWMs on the largest
packages. They can work together with the Advanced Control timer via the Timer Link
feature for synchronization or event chaining.
The counter can be frozen in debug mode.
Any of the standard timers can be used to generate PWM outputs. Each of the timers has
independent DMA request generations.
Basic timers TIM6 and TIM7
These timers are mainly used for DAC trigger generation. They can also be used as a
generic 16-bit time base.
Advanced control timers (TIM1 and TIM8)
The two advanced control timers (TIM1 and TIM8) can each be seen as a three-phase PWM
multiplexed on 6 channels. They 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
●
Complementary PWM outputs with programmable inserted dead-times.
If configured as a standard 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%).
The counter can be frozen in debug mode.
Many features are shared with those of the standard 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.

STM32F103xC, STM32F103xD, STM32F103xE
I²C bus
Up to two I²C bus interfaces can operate in multimaster and slave modes. They can support
standard and fast modes.
They support 7/10-bit addressing mode and 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.
Universal synchronous/asynchronous receiver transmitters (USARTs)
The STM32F103xC, STM32F103xD and STM32F103xE performance line embeds three
universal synchronous/asynchronous receiver transmitters (USART1, USART2 and
USART3) and two universal asynchronous receiver transmitters (UART4 and UART5).
These five 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 interface is able to communicate at speeds of up to 4.5 Mbit/s. The other
available interfaces communicate at up to 2.25 Mbit/s.
USART1, USART2 and USART3 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 except for UART5.
Serial peripheral interface (SPI)
Up to three SPIs are able to communicate up to 18 Mbits/s in slave and master modes in
full-duplex 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.
All SPIs can be served by the DMA controller.
Inter-integrated sound (I2S)
Two standard I2S interfaces (multiplexed with SPI2 and SPI3) are available, that can be
operated in master or slave mode. These interfaces can be configured to operate with 16/32
bit resolution, as input or output channels. Audio sampling frequencies from 8 kHz up to
48 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.
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 SD
Memory Card Specifications 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 also fully compliant with the CE-ATA digital
protocol Rev1.1.

STM32F103xC, STM32F103xD, STM32F103xE
Description
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.
Universal serial bus (USB)
The STM32F103xC, STM32F103xD and STM32F103xE performance line embed 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).
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
ADC (analog to digital converter)
Three 12-bit analog-to-digital converters are embedded into STM32F103xC, STM32F103xD
and STM32F103xE performance line devices and each ADC shares up to 21 external
channels, performing conversions in single-shot 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 standard timers (TIMx) and the advanced-control timers (TIM1
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.

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 chosen 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 STM32F103xC, STM32F103xD and
STM32F103xE performance line family. The DAC channels are triggered through the timer
update outputs that are also connected to different DMA channels.
Temperature sensor
The temperature sensor has to generate a linear voltage with any variation in temperature.
The conversion range is between 2 V < VDDA < 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.
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 respectively with SWDIO and SWCLK and a
specific sequence on the TMS pin is used to switch between JTAG-DP and SW-DP.
Embedded Trace Macrocell™
The ARM® Embedded Trace Macrocell provides a greater visibility of the instruction and
data flow inside the CPU core by streaming compressed data at a very high rate from the
STM32F10xxx 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 running debugger software. TPA
hardware is commercially available from common development tool vendors. It operates
with third party debugger software tools.

1. When the HSI is used as a PLL clock input, the maximum system clock frequency that can be achieved is
64 MHz.
2. For the USB function to be available, both HSE and PLL must be enabled, with the CPU running at either
48 MHz or 72 MHz.
3. To have an ADC conversion time of 1 µs, APB2 must be at 14 MHz, 28 MHz or 56 MHz.

1. I = input, O = output, S = supply, HiZ = high impedance.
2. FT = 5 V tolerant.
3. Function availability depends on the chosen device.
4. PC13, PC14 and PC15 are supplied through the power switch, and so their use in output mode is limited: they can be used
only in output 2 MHz mode with a maximum load of 30 pF and only one pin can be put in output mode at a time.
5. 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.
6. 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.
7. For the LQFP64 package, the pins number 5 and 6 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 the LQFP100/BGA100 and
LQFP144/BGA144 packages, PD0 and PD1 are available by default, so there is no need for remapping. For more details,
refer to Alternate function I/O and debug configuration section in the STM32F10xxx reference manual.

Electrical characteristics
5.1
Test conditions
Electrical characteristics
Unless otherwise specified, all voltages are referenced to VSS.
5.1.1
Minimum and maximum values
Unless otherwise specified the minimum and maximum values are guaranteed in the worst
conditions of ambient temperature, supply voltage and frequencies by tests in production on
100% of the devices with an ambient temperature at TA = 25 °C and TA = TAmax (given by
the selected temperature range).
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 (mean±3Σ).
5.1.2
Typical values
Unless otherwise specified, typical data are based on TA = 25 °C, VDD = 3.3 V (for the
2 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 (mean±2Σ).
5.1.3
Typical curves
Unless otherwise specified, all typical curves are given only as design guidelines and are
not tested.

Stresses above the absolute maximum ratings listed in Table 6: Voltage characteristics,
Table 7: Current characteristics, and Table 8: Thermal characteristics may cause permanent
damage to the device. These are stress ratings only and functional operation of the device
at these conditions is not implied. Exposure to maximum rating conditions for extended
periods may affect device reliability.

1. All main power (VDD, VDDA) and ground (VSS, VSSA) pins must always be connected to the external power
supply, in the permitted range.
2. IINJ(PIN) must never be exceeded (see Table 7: Current characteristics). This is implicitly insured if VIN
maximum is respected. If VIN maximum cannot be respected, the injection current must be limited
externally to the IINJ(PIN) value. A positive injection is induced by VIN>VDD while a negative injection is
induced by VIN < VSS.

supply, in the permitted range.
2. IINJ(PIN) must never be exceeded. This is implicitly insured if VIN maximum is respected. If VIN maximum
cannot be respected, the injection current must be limited externally to the IINJ(PIN) value. A positive
injection is induced by VIN > VDD while a negative injection is induced by VIN < VSS.
3. Negative injection disturbs the analog performance of the device. See note in Section 5.3.18: 12-bit ADC
characteristics.
4. When several inputs are submitted to a current injection, the maximum ΣIINJ(PIN) is the absolute sum of the
positive and negative injected currents (instantaneous values). These results are based on
characterization with ΣIINJ(PIN) maximum current injection on four I/O port pins of the device.

High-speed external clock
The high-speed external (HSE) clock can be supplied with a 4 to 16 MHz crystal/ceramic
resonator oscillator. All the information given in this paragraph are based on characterization
results obtained with typical external components specified in Table 22. In the application,
the resonator and the load capacitors have to be placed as close as possible to the oscillator
pins in order to minimize output distortion and startup stabilization time. Refer to the crystal
resonator manufacturer for more details on the resonator characteristics (frequency,
package, accuracy).

1. Resonator characteristics given by the crystal/ceramic resonator manufacturer.
2. For CL1 and CL2 it is recommended to use high-quality ceramic capacitors in the 5 pF to 25pF range (typ.),
designed for high-frequency applications, and 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. PCB and MCU pin capacitance must be
included when sizing CL1 and CL2 (10 pF can be used as a rough estimate of the combined pin and board
capacitance).
3. The relatively low value of the RF resistor offers a good protection against issues resulting from use in a
humid environment, due to the induced leakage and the bias condition change. However, it is
recommended to take this point into account if the MCU is used in tough humidity conditions.
4. Based on characterization results, not tested in production.

Low-speed external clock
The low-speed external (LSE) clock can be supplied with a 32.768 kHz crystal/ceramic
resonator oscillator. All the information given in this paragraph are based on characterization
results obtained with typical external components specified in Table 23. In the application,
the resonator and the load capacitors have to be placed as close as possible to the oscillator
pins in order to minimize output distortion and startup stabilization time. Refer to the crystal
resonator manufacturer for more details on the resonator characteristics (frequency,
package, accuracy).

Wakeup time from low-power mode
The wakeup times given in Table 26 is measured on a wakeup phase with a 8-MHz HSI RC
oscillator. The clock source used to wake up the device depends from the current operating
mode:
●
Stop or Standby mode: the clock source is the RC oscillator
●
Sleep mode: the clock source is the clock that was set before entering Sleep mode.
All timings are derived from tests performed under ambient temperature and VDD supply
voltage conditions summarized in Table 9.

EMC characteristics
Susceptibility tests are performed on a sample basis during device characterization.
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 1000-4-2 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 1000-4-4 standard.
A device reset allows normal operations to be resumed.
The test results are given in Table 40. They are based on the EMS levels and classes
defined in application note AN1709.

Designing hardened software to avoid noise problems
EMC characterization and optimization are performed at component level with a typical
application environment and simplified MCU software. 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).

Absolute maximum ratings (electrical sensitivity)
Based on three different tests (ESD, LU) using specific measurement methods, the device is
stressed in order to determine its performance in terms of electrical sensitivity.
Electrostatic discharge (ESD)
Electrostatic discharges (a positive then a negative pulse separated by 1 second) are
applied to the pins of each sample according to each pin combination. The sample size
depends on the number of supply pins in the device (3 parts × (n+1) supply pins). This test
conforms to the JESD22-A114/C101 standard.

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 characteristics
Output driving current
The GPIOs (general purpose input/outputs) can sink or source up to +/-8 mA, and sink
+20 mA (with a relaxed VOL).
In the user application, the number of I/O pins which can drive current must be limited to
respect the absolute maximum rating specified in Section 5.2:
●
The sum of the currents sourced by all the I/Os on VDD, plus the maximum Run
consumption of the MCU sourced on VDD, cannot exceed the absolute maximum rating
IVDD (see Table 7).
●
The sum of the currents sunk by all the I/Os on VSS plus the maximum Run
consumption of the MCU sunk on VSS cannot exceed the absolute maximum rating
IVSS (see Table 7).

3. ADC Accuracy vs. Negative Injection Current: Injecting negative current on any of the standard (nonrobust) 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 current.
Any positive injection current within the limits specified for IINJ(PIN) and ΣIINJ(PIN) in Section 5.3.13 does not

1. Refer to Table 57 for the values of CAIN, RAIN, RADC and CADC.
2. CPARASITIC must be added to CAIN. It represents the capacitance of the PCB (dependent on soldering and
PCB layout quality) plus the pad capacitance (3 pF). 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 in Figure 53 or Figure 54,
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.

Package characteristics
Thermal characteristics
The maximum chip junction temperature (TJmax) must never exceed the values given in
Table 9: General operating conditions on page 38.
The maximum chip-junction temperature, TJ max, in degrees Celsius, may be calculated
using the following equation:
TJ max = TA max + (PD max x ΘJA)
Where:
●
TA max is the maximum ambient temperature in °C,
●
ΘJA 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 = Σ (VOL × IOL) + Σ((VDD – VOH) × IOH),
taking into account the actual VOL / IOL and VOH / IOH of the I/Os at low and high level in the
application.

Selecting the product temperature range
When ordering the microcontroller, the temperature range is specified in the ordering
information scheme shown in Table 69: 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 STM32F103xC 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 × 3.5 V= 175 mW
PIOmax = 20 × 8 mA × 0.4 V + 8 × 20 mA × 1.3 V = 272 mW
This gives: PINTmax = 175 mW and PIOmax = 272 mW:
PDmax = 175 + 272 = 447 mW
Thus: PDmax = 464 mW
Using the values obtained in Table 68 TJmax is calculated as follows:
–
For LQFP100, 46 °C/W
TJmax = 82 °C + (46 °C/W × 447 mW) = 82 °C + 20.6 °C = 102.6 °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 69: 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 × 3.5 V= 70 mW
PIOmax = 20 × 8 mA × 0.4 V = 64 mW
This gives: PINTmax = 70 mW and PIOmax = 64 mW:
PDmax = 70 + 64 = 134 mW
Thus: PDmax = 134 mW
114/118
STM32F103xC, STM32F103xD, STM32F103xE
Package characteristics
Using the values obtained in Table 68 TJmax is calculated as follows:
–
For LQFP100, 46 °C/W
TJmax = 115 °C + (46 °C/W × 134 mW) = 115 °C + 6.2 °C = 121.2 °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 69: Ordering information scheme).
