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. Architecture and registers Harvard architecture • • 3-stage pipeline • 32-bit wide program memory bus - single cycle fetching for most instructions • X and Y 16-bit index registers - enabling indexed addressing modes with or without offset and read-modify-write type data manipulations • 8-bit accumulator • 24-bit program counter - 16-Mbyte linear memory space • 16-bit stack pointer - access to a 64 K-level stack • 8-bit condition code register - 7 condition flags for the result of the last instruction Addressing 20 addressing modes • • Indexed indirect addressing mode for look-up tables located anywhere in the address space • Stack pointer relative addressing mode for local variables and parameter passing Instruction set 80 instructions with 2-byte average instruction size • • Standard data movement and logic/arithmetic functions • 8-bit by 8-bit multiplication • 16-bit by 8-bit and 16-bit by 16-bit division • Bit manipulation • Data transfer between stack and accumulator (push/pop) with direct stack access • Data transfer using the X and Y registers or direct memory-to-memory transfers 4.2 Single wire interface module (SWIM) and debug module (DM) The single wire interface module and debug module permits non-intrusive, real-time in-circuit debugging and fast memory programming. 12/127 DocID14771 Rev 9 STM8S105xx SWIM Product overview 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 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 • 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 27 external interrupts on 6 vectors including TLI • Trap and reset interrupts 4.4 Flash program and data EEPROM memory • Up to 32 Kbytes of Flash program single voltage Flash memory • Up to 1 Kbytes 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 the figure below. The size of the UBC is programmable through the UBC option byte, 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 32 Kbytes minus UBC • • User-specific boot code (UBC): Configurable up to 32 Kbytes DocID14771 Rev 9 13/127 Product overview STM8S105xx 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 memor y Data memor y area ( 1 Kbyte) Option bytes UBC area Remains write protected during IAP Programmable area from 1 Kbyte (2 first pages) up to 32 Kbytes (1 page steps) Medium density Flash program memor y (up to 32 Kbytes)   Program memor y area Write access possible for IAP 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. • Clock in • Safe clock switching: registersources can be changed safely on the flynewrun mode through a configuration . The clock signal is not switched until the clock source is ready. The design guarantees glitch-free switching. consumption, • Clocktomanagement: To reduce poweror memory. the clock controller can stop the clock the core, individual peripherals • 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) 14/127 DocID14771 Rev 9 STM8S105xx Product overview - 16 MHz high-speed internal RC oscillator (HSI) 128 kHz low-speed internal RC (LSI) After reset, • Startup clock:The prescalerthe microcontroller restarts by default with an internal 2 MHz clock (HSI/8). ratio and clock source can be changed by the application program as soon as the code execution starts. system (CSS): This feature can be enabled by software. an • Clock securitythe internal RC (16 MHz/8) is automatically selected by theIfCSSHSE clock failure occurs, 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.

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. 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. 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. The beeper output port is only available through the alternate function remap option bit AFR7. 16/127 DocID14771 Rev 9 STM8S105xx Product overview 4.10 TIM1 - 16-bit advanced control timer This is a high-end timer designed for a wide range of control applications.

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). 28/127 DocID14771 Rev 9 STM8S105xx Memory and register map 6 6.1 Memory and register map Memory map Figure 7: Memory map 0x00 0000 RAM (2 Kbytes) 0x00 07FF 512 bytes stack Reser ved     0x00 4000 0x00 43FF 0x00 4400 0x00 47FF 0x00 4800 0x00 487F 0x00 4900 1 Kbyte data EEPROM Reser ved Option bytes Reser ved 0x00 4FFF 0x00 5000 GPIO and periph. reg. 0x00 57FF 0x00 5800 Reser ved 0x00 5FFF 0x00 6000 2 Kbytes boot ROM 0x00 67FF 0x00 6800 Reser ved 0x00 7EFF 0x00 7F00 0x00 7FFF 0x00 8000 0x00 807F CPU/SWIM/debug/ITC registers 32 interrupt vectors Flash program memor y (16 to 32 Kbytes) 0x00 FFFF 0x01 0000 Reser ved 0x02 7FFF The following table lists the boundary addresses for each memory size.

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 the table 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). Refer to the STM8S Flash programming manual (PM0051) and STM8 SWIM communication protocol and debug module user manual (UM0470) for information on SWIM programming procedures.

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. • fast transient voltage (positive and negative) is applied to and V • FTB: A burst ofpF capacitor, until a functional disturbance occurs. This testVconforms with through a 100 DD SS 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 (EMC design guide for STMicrocontrollers). 10.3.12.2 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.
