For more detailed information please refer to the corresponding family reference manual (RM0016). 4.1 Central processing unit STM8 The 8-bit STM8 core is designed for code efficiency and performance. It contains 6 internal registers which are directly addressable in each execution context, 20 addressing modes including indexed indirect and relative addressing and 80 instructions.

SWIM Single wire interface module for direct access to the debug module and memory programming. The interface can be activated in all device operation modes. The maximum data transmission speed is 145 bytes/ms. Debug module The non-intrusive debugging module features a performance close to a full-featured emulator. Beside memory and peripherals, also CPU operation can be monitored in realtime 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 Breakpoints on all program-memory instructions (software breakpoints) Two advanced breakpoints, 23 predefined configurations 4.3 Interrupt controller ● ● ● ● Nested interrupts with three software priority levels 32 interrupt vectors with hardware priority Up to 37 external interrupts on six vectors including TLI Trap and reset interrupts 14/103 Doc ID 14733 Rev 9 STM8S207xx, STM8S208xx Product overview 4.4 Flash program and data EEPROM memory ● ● ● ● Up to 128 Kbytes of high density Flash program single voltage Flash memory Up to 2K bytes true data EEPROM Read while write: Writing in data memory possible while executing code in program memory. User option byte area 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 bytes. 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 bytes. 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 Figure 2. The size of the UBC is programmable through the UBC option byte (Table 13.), in increments of 1 page (512 bytes) by programming the UBC option byte in ICP mode. This divides the program memory into two areas: ● ● Main program memory: Up to 128 Kbytes minus UBC User-specific boot code (UBC): Configurable up to 128 Kbytes 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. Figure 2. Flash memory organisation Data EEPROM memory Data memory area (2 Kbytes) Option bytes UBC area Remains write protected during IAP Up to 128 Kbytes Flash program memory Programmable area from 1 Kbyte (2 first pages) up to 128 Kbytes (1 page steps) Program memory area Write access possible for IAP Doc ID 14733 Rev 9 15/103 Product overview STM8S207xx, STM8S208xx 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 (fMASTER) coming from different oscillators to the core and the peripherals. It also manages clock gating for low power modes and ensures clock robustness. 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: – – – – 1-24 MHz high-speed external crystal (HSE) Up to 24 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.

You 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 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. 2. Timeout: At 16 MHz CPU clock the time-out period can be adjusted between 75 µs up to 64 ms. Refresh out of window: The downcounter is refreshed before its value is lower than the one stored in the window register. Doc ID 14733 Rev 9 17/103 Product overview STM8S207xx, STM8S208xx 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. 4.8 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 TIM3 input capture channel 1 for calibration 4.9 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. 4.10 TIM1 - 16-bit advanced control timer This is a high-end timer designed for a wide range of control applications.

Doc ID 14733 Rev 9 31/103 Pinouts and pin description STM8S207xx, STM8S208xx 5.2 Alternate function remapping As shown in the rightmost column of the pin description table, 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 the family reference manual, RM0016). 32/103 Doc ID 14733 Rev 9 STM8S207xx, STM8S208xx Memory and register map 6 6.1 Memory and register map Memory map Figure 8.

They are stored in a dedicated block of the memory. 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 12: Option bytes below. Option bytes can also be modified ‘on the fly’ by the application in IAP mode, except the ROP option that can only be modified in ICP mode (via SWIM).

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). ● ESD: 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 VDD and VSS through a 100 pF capacitor, until a functional disturbance occurs. This test conforms 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. 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 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 application note AN1015). Table 47.

The maximum chip-junction temperature, TJmax, in degrees Celsius, may be calculated using the following equation: TJmax = TAmax + (PDmax x ΘJA) Where: ● ● ● ● ● TAmax is the maximum ambient temperature in ° C ΘJA is the package junction-to-ambient thermal resistance in ° C/W PDmax is the sum of PINTmax and PI/Omax (PDmax = PINTmax + PI/Omax) PINTmax is the product of IDD and VDD, expressed in Watts. This is the maximum chip internal power. PI/Omax represents the maximum power dissipation on output pins, where: PI/Omax = Σ (VOL*IOL) + Σ((VDD-VOH)*IOH), and taking account of the actual VOL/IOL and VOH/IOH of the I/Os at low and high level in the application.

The following example shows how to calculate the temperature range needed for a given application. Assuming the following application conditions: ● ● ● ● ● Maximum ambient temperature TAmax= 82 °C (measured according to JESD51-2) IDDmax = 15 mA, VDD = 5.5 V Maximum eight standard I/Os used at the same time in output at low level with IOL = 10 mA, VOL= 2 V Maximum four high sink I/Os used at the same time in output at low level with IOL = 20 mA, VOL= 1.5 V Maximum two true open drain I/Os used at the same time in output at low level with IOL = 20 mA, VOL= 2 V PINTmax = 15 mA x 5.5 V = 82.5 mW PIOmax = (10 mA x 2 V x 8 ) + (20 mA x 2 V x 2) + (20 mA x 1.5 V x 4) = 360 mW This gives: PINTmax = 82.5 mW and PIOmax 360 mW: PDmax = 82.5 mW + 360 mW Thus: PDmax = 443 mW Using the values obtained in Table 57: Thermal characteristics on page 96 TJmax is calculated as follows for LQFP64 10 x 10 mm = 46 °C/W: TJmax = 82 °C + (46 °C/W x 443 mW) = 82 °C + 20 °C = 102 °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.
