Description
The STM8AF6213, STM8AF6223, STM8AF6223A and STM8AF6226 automotive 8-bit
microcontrollers offer 4 to 8 Kbyte of Flash program memory, plus integrated true data
EEPROM. The STM8S series and STM8AF series 8-bit microcontrollers reference manual
(RM0016) refers to devices in this family as low-density. They provide the following benefits:
performance, robustness and reduced system cost.
Device performance and robustness are ensured by advanced core and peripherals made
in a state-of-the-art technology, a 16 MHz clock frequency, robust I/Os, independent
watchdogs with separate clock source, and a clock security system.
The system cost is reduced thanks to an integrated true data EEPROM for up to
300 kwrite/erase cycles and a high system integration level with internal clock oscillators,
watchdog, and brown-out reset.
Full documentation is offered as well as a wide choice of development tools.

4.2
Single wire interface module (SWIM) and debug module (DM)
The single wire interface module together with an integrated debug module permit non-
intrusive, real-time in-circuit debugging and fast memory programming.
4.2.1
SWIM
Single wire interface module for direct access to the debug mode and memory
programming. The interface can be activated in all device operation modes.The maximum
data transmission speed is 145 byte/ms.
4.2.2
Debug module
The non-intrusive debugging module features a performance close to a full-featured
emulator. Besides memory and peripheral operation, CPU operation can also be monitored
in real-time by means of shadow registers.
R/W to RAM and peripheral registers in real-time
R/W access to all resources by stalling the CPU

Two advanced breakpoints, 23 predefined breakpoint configurations
4.3
Interrupt controller
Nested interrupts with three software priority levels
32 interrupt vectors with hardware priority
Up to 28 external interrupts on 7 vectors including TLI
Trap and reset interrupts
4.4
Flash program and data EEPROM memory
Up to 8 Kbyte of Flash program single voltage Flash memory
640 byte true data EEPROM
User option byte area
4.4.1
Write protection (WP)
Write protection of Flash program memory and data EEPROM is provided to avoid
unintentional overwriting of memory that could result from a user software malfunction.
There are two levels of write protection. The first level is known as MASS (memory access
security system). MASS is always enabled and protects the main Flash program memory,
data EEPROM and option byte.
To perform in-application programming (IAP), this write protection can be removed by
writing a MASS key sequence in a control register. This allows the application to write to
data EEPROM, modify the contents of main program memory or the device option byte.
A second level of write protection, can be enabled to further protect a specific area of
memory known as UBC (user boot code). Refer to the figure below.
14/106
DocID025118 Rev 5
STM8AF6213/23/23A/26
Product overview
The size of the UBC is programmable through the UBC option byte, in increments of 1 page
(64-byte block) by programming the UBC option byte in ICP mode.
This divides the program memory into two areas:
Main program memory: up to 8 Kbyte minus UBC
User-specific boot code (UBC): configurable up to 8 Kbyte
The UBC area remains write-protected during in-application programming. This means that
the MASS keys do not unlock the UBC area. It protects the memory used to store the boot
program, specific code libraries, reset and interrupt vectors, the reset routine and usually
the IAP and communication routines.

4.4.2
Read-out protection (ROP)
The read-out protection blocks reading and writing the Flash program memory and data
EEPROM memory in ICP mode (and debug mode). Once the read-out protection is
activated, any attempt to toggle its status triggers a global erase of the program and data
memory. Even if no protection can be considered as totally unbreakable, the feature
provides a very high level of protection for a general purpose microcontroller.

4.5
Clock controller
The clock controller distributes the system clock (f
) coming from different oscillators
MASTER
to the core and the peripherals. It also manages clock gating for low-power modes and
ensures clock robustness.
4.5.1
Features
Clock prescaler: to get the best compromise between speed and current consumption
the clock frequency to the CPU and peripherals can be adjusted by a programmable
prescaler.
Safe clock switching: Clock sources can be changed safely on the fly in Run mode
through a configuration register. The clock signal is not switched until the new clock
source is ready. The design guarantees glitch-free switching.
Clock management: To reduce power consumption, the clock controller can stop the
clock to the core, individual peripherals or memory.
Master clock sources: four different clock sources can be used to drive the master
clock:
–
–
–
–
1-16 MHz high-speed external crystal (HSE)
Up to 16 MHz high-speed user-external clock (HSE user-ext)
16 MHz high-speed internal RC oscillator (HSI)
128 kHz low-speed internal RC (LSI)
Startup clock: after reset, the microcontroller restarts by default with an internal 2 MHz
clock (HSI/8). The prescaler ratio and clock source can be changed by the application
program as soon as the code execution starts.
Clock security system (CSS): this feature can be enabled by software. If an HSE
clock failure occurs, the internal RC (16 MHz/8) is automatically selected by the CSS
and an interrupt can optionally be generated.
Configurable main clock output (CCO): This outputs an external clock for use by the
application.

Power management
For efficient power management, the application can be put in one of four different low-
power modes. Users can configure each mode to obtain the best compromise between
lowest power consumption, fastest start-up time and available wakeup sources.
Wait mode: in this mode, the CPU is stopped but peripherals are kept running. The
wakeup is performed by an internal or external interrupt or reset.
Active-halt mode with regulator on: in this mode, the CPU and peripheral clocks are
stopped. An internal wakeup is generated at programmable intervals by the auto wake
up unit (AWU). The main voltage regulator is kept powered on, so current consumption
is higher than in Active-halt mode with regulator off, but the wakeup time is faster.
Wakeup is triggered by the internal AWU interrupt, external interrupt or reset.
Active-halt mode with regulator off: this mode is the same as Active-halt with
regulator on, except that the main voltage regulator is powered off, so the wake up time
is slower.
Halt mode: in this mode the microcontroller uses the least power. The CPU and
peripheral clocks are stopped, the main voltage regulator is powered off. Wakeup is
triggered by external event or reset.
4.7
Watchdog timers
The watchdog system is based on two independent timers providing maximum security to
the applications.
Activation of the watchdog timers is controlled by option bytes or by software. Once
activated, the watchdogs cannot be disabled by the user program without performing a
reset.
Window watchdog timer
The window watchdog is used to detect the occurrence of a software fault, usually
generated by external interferences or by unexpected logical conditions, which cause the
application program to abandon its normal sequence.
The window function can be used to trim the watchdog behavior to match the application
timing perfectly. The application software must refresh the counter before time-out and
during a limited time window.
A reset is generated in two situations:
1. Timeout: at 16 MHz CPU clock the time-out period can be adjusted between 75 µs up
to 64 ms.
2. Refresh out of window: the downcounter is refreshed before its value is lower than the
one stored in the window register.

Independent watchdog timer
The independent watchdog peripheral can be used to resolve processor malfunctions due to
hardware or software failures.
It is clocked by the 128 kHz LSI internal RC clock source, and thus stays active even in case
of a CPU clock failure.
The IWDG time base spans from 60 µs to 1 s

Auto wakeup counter
Used for auto wakeup from active halt mode
Clock source: Internal 128 kHz internal low frequency RC oscillator or external clock
LSI clock can be internally connected to TIM1 input capture channel 1 for calibration
Beeper
The beeper function outputs a signal on the BEEP pin for sound generation. The signal is in
the range of 1, 2 or 4 kHz.
The beeper output port is only available through the alternate function remap option bit
AFR7.

1. I/O pins used simultaneously for high current source/sink must be uniformly spaced around the package. In addition, the
total driven current must respect the absolute maximum ratings ( see Section: Absolute maximum ratings).
2. When the MCU is in Halt/Active-halt mode, PA1 is automatically configured in input weak pull-up and cannot be used for
waking up the device. In this mode, the output state of PA1 is not driven. It is recommended to use PA1 only in input mode
if Halt/Active-halt is used in the application.
3. In the open-drain output column, ‘T’ defines a true open-drain I/O (P-buffer, weak pull-up, and protection diode to VDD are
not implemented)
4. The PD1 pin is in input pull-up during the reset phase and after internal reset release.

1. I/O pins used simultaneously for high current source/sink must be uniformly spaced around the package. In addition, the
total driven current must respect the absolute maximum ratings ( see Section: Absolute maximum ratings).
2. When the MCU is in Halt/Active-halt mode, PA1 is automatically configured in input weak pull-up and cannot be used for
waking up the device. In this mode, the output state of PA1 is not driven. It is recommended to use PA1 only in input mode if
Halt/Active-halt is used in the application.
3. In the open-drain output column, ‘T’ defines a true open-drain I/O (P-buffer, weak pull-up, and protection diode to VDD are
not implemented).
4. The PD1 pin is in input pull-up during the reset phase and after internal reset release.

Alternate function remapping
As shown in the rightmost column of Table 6, Table 7 and Table 8 some alternate functions
can be remapped at different I/O ports by programming one of eight AFR (alternate function
remap) option bits. Refer to Section 8: Option bytes on page 47. When the remapping
option is active, the default alternate function is no longer available.
To use an alternate function, the corresponding peripheral must be enabled in the peripheral
registers.
Alternate function remapping does not effect GPIO capabilities of the I/O ports (see the
GPIO section of STM8S series and STM8AF series 8-bit microcontrollers reference manual,
RM0016).

Option bytes
Option bytes contain configurations for device hardware features as well as the memory
protection of the device. Except for the ROP (read-out protection) byte, each option byte has
to be stored twice, in a regular form (OPTx) and a complemented one (NOPTx) for
redundancy.
Option bytes can be modified in ICP mode (via SWIM) by accessing the EEPROM address
shown in Table 14: Option bytes below.
Option bytes can also be modified ‘on the fly’ by the application in IAP mode, except the
ROP and UBC options that can only be modified in ICP mode (via SWIM).
Refer to the STM8 Flash programming manual (PM0051) and STM8 SWIM communication
protocol and debug module user manual (UM0470) for information on SWIM programming
procedures.

1. Data based on characterization results, not tested in production.
2. All power (VDD, VDDIO, VDDA) and ground (VSS, VSSIO, VSSA) pins must always be connected to the
external supply.
3. 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. For true open-drain pads,
there is no positive injection current, and the corresponding VIN maximum must always be respected.
4. ADC accuracy vs. negative injection current: Injecting negative current on any of the 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
∑IINJ(PIN) in the I/O port pin characteristics section does not affect the ADC accuracy
5. 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.

2. Reset is always generated after a tTEMP delay. The application must ensure that VDD is still above the
minimum operating voltage (VDD min) when the tTEMP delay has elapsed.
3. There is inrush current into VDD present after device power on to charge CEXT capacitor. This inrush energy
depends from CEXT capacitor value. For example, a CEXT of 1μF requires Q=1 μF x 1.8V = 1.8 μC.

HSE crystal/ceramic resonator oscillator
The HSE clock can be supplied with a 1 to 16 MHz crystal/ceramic resonator oscillator. All
the information given in this paragraph is based on characterization results with specified
typical external components. 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
(frequency, package, accuracy...).

2. The oscillator selection can be optimized in terms of supply current using a high quality resonator with small Rm value.
Refer to the crystal manufacturer for more details.
3. Data based on characterization results, not tested in production.
4. tSU(HSE) is the startup time measured from the moment it is enabled (by software) until a stabilized 16 MHz oscillation is
reached. The value is measured for a standard crystal resonator and it can vary significantly with the crystal manufacturer.

The reset network shown in Figure 35 protects the device against parasitic resets. The user
must ensure that the level on the NRST pin can go below V
max (see Table 51:
IL(NRST)
NRST pin characteristics), otherwise the reset is not taken into account internally.
For power consumption sensitive applications, the external reset capacitor value can be
reduced to limit the charge/discharge current. If NRST signal is used to reset external
circuitry, attention must be taken to the charge/discharge time of the external capacitor to
fulfill the external devices reset timing conditions. Minimum recommended capacity is
100 nF.

1. During the sample time the input capacitance CAIN (3 pF max) can be charged/discharged by the external
source. The internal resistance of the analog source must allow the capacitance to reach its final voltage
level within tS. After the end of the sample time tS, changes of the analog input voltage have no effect on
the conversion result. Values for the sample clock tS depend on programming.

1. Max value is based on characterization, not tested in production.
2. ADC accuracy vs. negative injection current: Injecting negative current on any of the 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
IINJ(PIN) in the I/O port pin characteristics section does not affect the ADC accuracy.

EMC characteristics
Susceptibility tests are performed on a sample basis during product characterization.
Functional EMS (electromagnetic susceptibility)
While executing a simple application (toggling 2 LEDs through I/O ports), the product is
stressed by two electromagnetic events until a failure occurs (indicated by the LEDs).
FESD: Functional electrostatic discharge (positive and negative) is applied on all pins
of the device until a functional disturbance occurs. This test conforms with the IEC
61000-4-2 standard.
FTB: A burst of fast transient voltage (positive and negative) is applied to V and V
through a 100 pF capacitor, until a functional disturbance occurs. This test conforms
DD
SS
with the IEC 61000-4-4 standard.
A device reset allows normal operations to be resumed. The test results are given in the
table below 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.
Prequalification trials
Most of the common failures (unexpected reset and program counter corruption) can be
recovered by applying 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 the application note reference AN1015).

Absolute maximum ratings (electrical sensitivity)
Based on three different tests (ESD, DLU and LU) using specific measurement methods,
the product is stressed to determine its performance in terms of electrical sensitivity. For
more details, refer to the application note AN1181.
Electrostatic discharge (ESD)
Electrostatic discharges (one positive then one negative pulses 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 pin). One model
can be simulated: Human body model. This test conforms to the JESD22-A114A/A115A

Selecting the product temperature range
When ordering the microcontroller, the temperature range is specified in the order code (see
Section 11: Ordering information).
The following example shows how to calculate the temperature range needed for a given
application.

DocID025118 Rev 5
STM8AF6213/23/23A/26

Assuming the following application conditions:
Maximum ambient temperature T = 75 °C (measured according to JESD51-2),
Amax
I
= 8 mA, V = 5 V
DDmax
DD
Maximum 20 I/Os used at the same time in output at low level with:

I
OL
OL
P
P
= 8 mA x 5 V= 400 mW
INTmax
= 20 x 8 mA x 0.4 V = 64 mW
IOmax
This gives: P
= 400 mW and P
64 mW:
IOmax
INTmax
P
= 400 mW + 64 mW
Dmax
Thus: P
= 464 mW.
Dmax
Using the values obtained in Table 63: Thermal characteristics on page 98 T
is
Jmax
calculated as follows:
For LQFP32 60 °C/W
T
= 75 °C + (60 °C/W x464 mW) = 75 °C + 27.8 °C = 102.8 °C
Jmax
This is within the range of the suffix C version parts (-40 < T < 125 °C).
J
Parts must be ordered at least with the temperature range suffix C.
