1. 64 KB RAM for 256 KB Flash are available on devices delivered in CSP packages only.
2. For the LQFP100 and BGA100 packages, only FSMC Bank1 and Bank2 are available. Bank1 can only
support a multiplexed NOR/PSRAM memory using the NE1 Chip Select. Bank2 can only support a 16- or
8-bit NAND Flash memory using the NCE2 Chip Select. The interrupt line cannot be used since Port G is
not available in this package.
3. The SPI2 and SPI3 interfaces give the flexibility to work in an exclusive way in either the SPI mode or the
I2S audio mode.

STM32F103xC, STM32F103xD, STM32F103xE
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 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-density and high-density devices are an extension of the STM32F103x8/B mediumdensity devices, they are specified in the STM32F103x4/6 and STM32F103xC/D/E
datasheets, respectively. Low-density 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 family.
The STM32F103x4, STM32F103x6, STM32F103xC, STM32F103xD and STM32F103xE
are a drop-in replacement for the STM32F103x8/B 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.

Overview
2.3.1
ARM® Cortex™-M3 core with embedded Flash and SRAM
Description
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.
With its embedded ARM core, STM32F103xC, STM32F103xD and STM32F103xE
performance line family is compatible with all ARM tools and software.
Figure 1 shows the general block diagram of the device family.
2.3.2
Embedded Flash memory
Up to 512 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
Up to 64 Kbytes of embedded SRAM accessed (read/write) at CPU clock speed with 0 wait
states.
2.3.5
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: PC
Card/Compact Flash, SRAM, 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 NAND Flash and PC Card
●
The targeted frequency, fCLK, is HCLK/2, so external access is at 36 MHz when HCLK
is at 72 MHz and external access is at 24 MHz when HCLK is at 48 MHz

Description
2.3.6
STM32F103xC, STM32F103xD, STM32F103xE
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.
2.3.7
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.
●
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.
2.3.8
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.
2.3.9
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.

2.3.10
Description
Boot modes
At startup, boot pins are used to select one of three boot options:
●
Boot from user Flash: you have an option to boot from any of two memory banks. By
default, boot from Flash memory bank 1 is selected. You can choose to boot from Flash
memory bank 2 by setting a bit in the option bytes.
●
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.
2.3.11
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, DAC, Reset blocks,
RCs and PLL (minimum voltage to be applied to VDDA is 2.4 V when the ADC or DAC
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 12: Power supply scheme.
2.3.12
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. Refer to
Table 12: Embedded reset and power control block characteristics for the values of
VPOR/PDR and VPVD.
2.3.13
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.
Doc ID 14611 Rev 8

Description
2.3.14
STM32F103xC, STM32F103xD, STM32F103xE
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.
●
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.
2.3.15
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.
2.3.16
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 when VDD power is not present.
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

Description
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.
2.3.17
Timers and watchdogs
The high-density STM32F103xx performance line devices include up to two advancedcontrol timers, up to four general-purpose timers, two basic timers, two watchdog timers and
a SysTick timer.

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 have complementary PWM outputs with
programmable inserted dead-times. 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
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%).
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.

Description
STM32F103xC, STM32F103xD, STM32F103xE
General-purpose timers (TIMx)
There are up to 4 synchronizable general-purpose 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 onepulse mode output. This gives up to 16 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.
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.
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.
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:
2.3.18
●
A 24-bit down counter
●
Autoreload capability
●
Maskable system interrupt generation when the counter reaches 0.
●
Programmable clock source
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.

Description
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.
2.3.20
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.
2.3.21
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.
2.3.22
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.
2.3.23
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.

Description
2.3.24
STM32F103xC, STM32F103xD, STM32F103xE
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).
2.3.25
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.
2.3.26
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 general-purpose 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.
2.3.27
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.

STM32F103xC, STM32F103xD, STM32F103xE
Description
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.
2.3.28
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.
2.3.29
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.
2.3.30
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. I = input, O = output, S = supply.
2. FT = 5 V tolerant.
3. Function availability depends on the chosen device.
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 WLCSP 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. 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.
10. For devices delivered in LQFP64 packages, the FSMC function is not available.

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±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.

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 13: 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 when explicitly mentioned
●
The Flash memory access time is adjusted to the fHCLK frequency (0 wait state from 0
to 24 MHz, 1 wait state from 24 to 48 MHz and 2 wait states above)
●
Prefetch in ON (reminder: this bit must be set before clock setting and bus prescaling)
●
When the peripherals are enabled fPCLK1 = fHCLK/2, fPCLK2 = fHCLK
The parameters given in Table 14, Table 15 and Table 16 are derived from tests performed
under ambient temperature and VDD supply voltage conditions summarized in Table 10.

High-speed external clock generated from a crystal/ceramic resonator
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 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).

1. Resonator characteristics given by the crystal/ceramic resonator manufacturer.
2. Based on characterization results, not tested in production.
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. 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
For CL1 and CL2, it is recommended to use high-quality external ceramic capacitors in the
5 pF to 25 pF range (typ.), designed for high-frequency applications, and selected to match
the requirements of the crystal or resonator (see Figure 22). 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. Refer to the application note AN2867 “Oscillator design guide for ST
microcontrollers” available from the ST website www.st.com.

tSU(LSE) is the startup time measured from the moment it is enabled (by software) to a stabilized 32.768 kHz oscillation is
reached. 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 (see Figure 23).
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 27 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 10.

Electrical characteristics
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 41. 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...)

Electrical characteristics
STM32F103xC, STM32F103xD, STM32F103xE
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.

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.

I/O current injection characteristics
As a general rule, current injection to the I/O pins, due to external voltage below VSS or
above VDD (for standard, 3 V-capable I/O pins) should be avoided during normal product
operation. However, in order to give an indication of the robustness of the microcontroller in
cases when abnormal injection accidentally happens, susceptibility tests are performed on a
sample basis during device characterization.
Functional susceptibilty to I/O current injection
While a simple application is executed on the device, the device is stressed by injecting
current into the I/O pins programmed in floating input mode. While current is injected into the
I/O pin, one at a time, the device is checked for functional failures.
The failure is indicated by an out of range parameter: ADC error above a certain limit (>5
LSB TUE), out of spec current injection on adjacent pins or other functional failure (for
example reset, oscillator frequency deviation).
The test results are given in Table 45

2. Hysteresis voltage between Schmitt trigger switching levels. Based on characterization, not tested in production.
3. With a minimum of 100 mV.
4. Leakage could be higher than max. if negative current is injected on adjacent pins.
5. Pull-up and pull-down resistors are designed with a true resistance in series with a switchable PMOS/NMOS. This
MOS/NMOS contribution to the series resistance is minimum (~10% order).
All I/Os are CMOS and TTL compliant (no software configuration required). Their
characteristics cover more than the strict CMOS-technology or TTL parameters. The
coverage of these requirements is shown in Figure 42 and Figure 43 for standard I/Os, and
in Figure 44 and Figure 45 for 5 V tolerant I/Os.

Output driving current
The GPIOs (general purpose input/outputs) can sink or source up to +/-8 mA, and sink or
source up to +/- 20 mA (with a relaxed VOL/VOH).
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:
88/130
●
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 8).
●
The sum of the currents sunk by all the I/Os on VSS plus the maximum Run

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.

1. Refer to Table 59 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 59 or Figure 60,
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.

Thermal characteristics
The maximum chip junction temperature (TJmax) must never exceed the values given in
Table 10: General operating conditions on page 42.
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.

Package characteristics
Selecting the product temperature range
When ordering the microcontroller, the temperature range is specified in the ordering
information scheme shown in Table 74: 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, STM32F103xD and
STM32F103xE 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 = 447 mW
Using the values obtained in Table 73 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 74: 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

121/130
Package characteristics
STM32F103xC, STM32F103xD, STM32F103xE
Using the values obtained in Table 73 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 74: Ordering information scheme).
