2.2
Overview
2.2.1
ARM® Cortex™-M3 core with embedded Flash and SRAM
The ARM Cortex™-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 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.
The STM32F100xx value line family having an embedded ARM core, is therefore
compatible with all ARM tools and software.
2.3
Embedded Flash memory
Up to 128 Kbytes of embedded Flash memory is available for storing programs and data.
2.4
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.
2.5
Embedded SRAM
Up to 8 Kbytes of embedded SRAM accessed (read/write) at CPU clock speed with 0 wait
states.

Description
Nested vectored interrupt controller (NVIC)
The STM32F100xx value line embeds a nested vectored interrupt controller able to handle
up to 41 maskable interrupt channels (not including the 16 interrupt lines of Cortex™-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 for 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 minimal interrupt
latency.
2.7
External interrupt/event controller (EXTI)
The external interrupt/event controller consists of 18 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 80 GPIOs can be connected
to the 16 external interrupt lines.
2.8
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 4-24 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 APB domains is 24 MHz.
2.9
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.

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.
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/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.
2.12
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.
2.13
Low-power modes
The STM32F100xx value 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.
16/84
Doc ID 16455 Rev 2
STM32F100x4, STM32F100x6, STM32F100x8, STM32F100xB
Description
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 or the RTC alarm.
●
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), a 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.
2.14
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, DAC, I2C, USART, all timers and
ADC.
2.15
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.
2.16
Timers and watchdogs
The STM32F100xx devices include an advanced-control timer, six general-purpose timers,
two basic timers and two watchdog timers.
Table 3 compares the features of the advanced-control, general-purpose and basic timers.

Advanced-control timer (TIM1)
The advanced-control timer (TIM1) can be seen as a three-phase PWM multiplexed on 6
channels. 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 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.
2.16.2
General-purpose timers (TIM2, TIM3, TIM4, TIM15, TIM16 & TIM17)
There are six synchronizable general-purpose timers embedded in the STM32F100xx
devices (see Table 3 for differences). Each general-purpose timers can be used to generate
PWM outputs, or as simple time base.
TIM2, TIM3, TIM4
STM32F100xx devices feature three synchronizable 4-channels general-purpose timers.
These timers are based on a 16-bit auto-reload up/downcounter and a 16-bit prescaler.
They 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 TIM2, TIM3, TIM4 general-purpose timers can work together or with the TIM1
advanced-control timer via the Timer Link feature for synchronization or event chaining.
TIM2, TIM3, TIM4 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.
Their counters can be frozen in debug mode.
TIM15, TIM16 and TIM17
These timers are based on a 16-bit auto-reload upcounter and a 16-bit prescaler.
TIM15 has two independent channels, whereas TIM16 and TIM17 feature one single
channel for input capture/output compare, PWM or one-pulse mode output.
The TIM15, TIM16 and TIM17 timers can work together, and TIM15 can also operate with
TIM1 via the Timer Link feature for synchronization or event chaining.
TIM15 can be synchronized with TIM16 and TIM17.
TIM15, TIM16, and TIM17 have a complementary output with dead-time generation and
independent DMA request generation
Their counters can be frozen in debug mode.
2.16.3
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.
2.16.4
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 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.
2.16.5
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.

This timer is dedicated for OS, but could also be used as a standard down counter. It
features:
2.17
●
A 24-bit down counter
●
Autoreload capability
●
Maskable system interrupt generation when the counter reaches 0.
●
Programmable clock source
I²C bus
The I²C 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.
The interface can be served by DMA and it supports SM Bus 2.0/PM Bus.
2.18
Universal synchronous/asynchronous receiver transmitter
(USART)
The STM32F100xx value line embeds three universal synchronous/asynchronous receiver
transmitters (USART1, USART2 and USART3).
The available USART interfaces communicate at up to 3 Mbit/s. They provide hardware
management of the CTS and RTS signals, they support IrDA SIR ENDEC, the
multiprocessor communication mode, the single-wire half-duplex communication mode and
have LIN Master/Slave capability.
The USART interfaces can be served by the DMA controller.
2.19
Serial peripheral interface (SPI)
Up to two SPIs are able to communicate up to 12 Mbit/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.
Both SPIs can be served by the DMA controller.
2.20
HDMI (high-definition multimedia interface) consumer
electronics control (CEC)
The STM32F100xx value line embeds a HDMI-CEC controller that provides hardware
support of consumer electronics control (CEC) (Appendix supplement 1 to the HDMI
standard).
This protocol provides high-level control functions between all audiovisual products in an
environment. It is specified to operate at low speeds with minimum processing and memory
overhead.

2.21
Description
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.
2.22
Remap capability
This feature allows the use of a maximum number of peripherals in a given application.
Indeed, alternate functions are available not only on the default pins but also on other
specific pins onto which they are remappable. This has the advantage of making board
design and port usage much more flexible.
For details refer to Table 4: STM32F100xx pin definitions; it shows the list of remappable
alternate functions and the pins onto which they can be remapped. See the STM32F10xxx
reference manual for software considerations.
2.23
ADC (analog-to-digital converter)
The 12-bit analog to digital converter has up to 16 external channels and performs
conversions in single-shot or scan modes. In scan mode, automatic conversion is performed
on a selected group of analog inputs.
The ADC can be served by the DMA controller.
An analog watchdog feature allows very precise monitoring of the converted voltage of one,
some or all selected channels. An interrupt is generated when the converted voltage is
outside the programmed thresholds.
2.24
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 noninverting configuration.
This dual digital Interface supports the following features:
●
two DAC converters: one for each output channel
●
up to 10-bit output
●
left or right data alignment in 12-bit mode
●
synchronized update capability
●
noise-wave generation
●
triangular-wave generation
●
dual DAC channels’ independent or simultaneous conversions
●
DMA capability for each channel
●
external triggers for conversion
●

Description
STM32F100x4, STM32F100x6, STM32F100x8, STM32F100xB
Eight DAC trigger inputs are used in the STM32F100xx. The DAC channels are triggered
through the timer update outputs that are also connected to different DMA channels.
2.25
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 ADC1_IN16 input channel which is used to convert the sensor output
voltage into a digital value.
2.26
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.

1. I = input, O = output, S = supply, HiZ= high impedance.
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 peripherals that is included. For example, if a device has only one SPI, two USARTs and two timers, they will be
called SPI1, USART1 & USART2 and TIM2 & TIM 3, respectively. Refer to Table 2 on page 11.
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 and since the switch only sinks a limited amount of current
(3 mA), the use of GPIOs PC13 to PC15 in output mode is restricted: 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. I2C2 is not present on low-density value line devices.
9. SPI2 is not present on low-density value line devices.
10. TIM4 is not present on low-density value line devices.
11. 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.
12. 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.

Parameter 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±3).
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±2).
5.1.3
Typical curves
Unless otherwise specified, all typical curves are given only as design guidelines and are
not tested.

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 6: 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> VINmax 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 5.3.16: 12-bit ADC
characteristics.
4. When several inputs are submitted to a current injection, the maximum IINJ(PIN) is the absolute sum of the
positive and negative injected currents (instantaneous values). These results are based on
characterization with IINJ(PIN) maximum current injection on four I/O port pins of the device.

Supply current characteristics
The current consumption is a function of several parameters and factors such as the
operating voltage, ambient temperature, I/O pin loading, device software configuration,
operating frequencies, I/O pin switching rate, program location in memory and executed
binary code.
The current consumption is measured as described in Figure 11: Current consumption
measurement scheme.
All Run-mode current consumption measurements given in this section are performed with a
reduced code that gives a consumption equivalent to Dhrystone 2.1 code.
Maximum current consumption
The MCU is placed under the following conditions:
●
All I/O pins are in input mode with a static value at VDD or VSS (no load)
●
All peripherals are disabled except if it is explicitly mentioned
●
Prefetch in on (reminder: this bit must be set before clock setting and bus prescaling)
●
When the peripherals are enabled fPCLK1 = fHCLK, fPCLK2 = fHCLK
The parameters given in Table 12 are derived from tests performed under the ambient
temperature and VDD supply voltage conditions summarized in Table 8.

High-speed external clock generated from a crystal/ceramic resonator
The high-speed external (HSE) clock can be supplied with a 4 to 24 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 21. 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. Based on characterization, not tested in production.
3. 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. 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.
4. 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.
5. tSU(HSE) is the startup time measured from the moment it is enabled (by software) to a stabilized 8 MHz
oscillation is reached. This value is measured for a standard crystal resonator and it can vary significantly
with the crystal manufacturer

Low-speed external clock generated from a crystal/ceramic resonator
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 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

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.

Wakeup time from low-power mode
The wakeup times given in Table 25 are measured on a wakeup phase with an 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 the ambient temperature and VDD supply

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 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 29. 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 pre
qualification 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.

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

1. Refer to Table 41 for the values of RAIN, RADC and CADC.
2. Cparasitic represents the capacitance of the PCB (dependent on soldering and PCB layout quality) plus the
pad capacitance (roughly 7 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 33 or Figure 34,
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 8: General operating conditions on page 34.
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 × IOL) + ((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 52: 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 STM32F10xxx 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: 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
mode 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 = 447 mW
Using the values obtained in Table 51 TJmax is calculated as follows:
–
For LQFP64, 45 °C/W
TJmax = 82 °C + (45 °C/W × 447 mW) = 82 °C + 20.1 °C = 102.1 °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 52: 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

STM32F100x4, STM32F100x6, STM32F100x8, STM32F100xB
Package characteristics
Using the values obtained in Table 51 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 52: Ordering information scheme).
