transmitter wwdg: window watchdog 3.1 low-power modes the medium-density stm8l151x4/6 and stm8 l152x4/6 devices support five low power modes to achieve the best compromise betwee n low power consumption, short startup time and available wakeup sources: ? wait mode : the cpu clock is stopped, but selected peripherals keep running. an internal or external interrupt, event or a re set can be used to exit the microcontroller from wait mode (wfe or wfi mode ). wait consumption: refer to table 21 . ? low power run mode : the cpu and the selected peripherals are running. execution is done from ram with a low speed oscillator (lsi or lse). flash and data eeprom are stopped and the voltage regulator is configured in ultra-low-power mode. the microcontroller enters low power run mode by software and can exit from this mode by software or by a reset. all interrupts must be masked. they cannot be used to exit the microcontroller from this mode. low power run mode consumption: refer to table 22 . ? low power wait mode: this mode is entered when executing a wait for event in low power run mode. it is similar to low powe r run mode except that the cpu clock is stopped. the wakeup from this mode is triggered by a reset or by an internal or external event (peripheral event generate d by the timers, serial interfaces, dma controller (dma1), comparators and i/o ports). when the wakeup is triggered by an event, the system goes back to low power run mode. all interrupts must be masked. they cannot be used to exit the microcontroller from this mode. low power wait mode consumption: refer to table 23 . ? active-halt mode : cpu and peripheral clocks are stopped, except rtc. the wakeup can be triggered by rtc interrupts, external interrupts or reset. active-halt consumption: refer to table 24 and table 25 . ? halt mode : cpu and peripheral clocks are sto pped, the device remains powered on. the ram content is preserved. the wakeup is triggered by an external interrupt or reset. a few peripheral s have also a wakeup from halt capability. switching off the internal reference voltage reduces power co nsumption. through software configuration it is also possible to wake up the device without waiting for the internal reference voltage wakeup time to have a fast wakeup time of 5 s. halt consumption: refer to table 26 . functional overview stm8l151x4/6, stm8l152x4/6 16/142

docid15962 rev 15 17/142 stm8l151x4/6, stm8l152x4/6 functional overview 58 3.3 reset and supply management 3.3.1 power supply scheme the device requires a 1.65 v to 3.6 v operating supply voltage (v dd ). the external power supply pins must be connected as follows: ? v ss1 ; v dd1 = 1.8 to 3.6 v, down to 1.65 v at power down: external power supply for i/os and for the internal regulator. provided externally through v dd1 pins, the corresponding ground pin is v ss1 . ? v ssa; v dda = 1.8 to 3.6 v, down to 1.65 v at power down: external power supplies for analog peripherals (minimum voltage to be applied to v dda is 1.8 v when the adc1 is used). v dda and v ssa must be connected to v dd1 and v ss1 , respectively. ? v ss2 ; v dd2 = 1.8 to 3.6 v, down to 1.65 v at power down: external power supplies for i/os. v dd2 and v ss2 must be connected to v dd1 and v ss1 , respectively. ? v ref+ ; v ref- (for adc1): external reference voltage for adc1. must be provided externally through v ref+ and v ref- pin. ? v ref+ (for dac): external voltage reference for dac must be provided externally through v ref+ . 3.3.2 power supply supervisor the device has an integrated zeropower power-on reset (por)/power-down reset (pdr), coupled with a brownout reset (bor) circ uitry. at power-on, bor is always active, and ensures proper operation starting from 1.8 v. after the 1.8 v bor threshold is reached, the option byte loading process starts, either to confirm or modify default thresholds, or to disable bor permanently (in which case, the v dd min value at power down is 1.65 v). five bor thresholds are available thro ugh option bytes, starting from 1.8 v to 3 v. to reduce the power consumption in halt mode, it is possible to automatically switch off the internal reference voltage (and consequently the bor) in halt mode. the device remains under reset when v dd is below a specified threshold, v por/pdr or v bor , without the need for any external reset circuit. the device features an embedded programmable voltage detector (pvd) that monitors the v dd /v dda power supply and compares it to the v pvd threshold. this pvd offers 7 different levels between 1.85 v and 3.05 v, chosen by software, with a step around 200 mv. an interrupt can be generated when v dd /v dda drops below the v pvd threshold and/or when v dd /v dda is higher than the v pvd 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. 3.3.3 voltage regulator the medium-density stm8l151x4/6 and st m8l152x4/6 embeds an internal voltage regulator for generating the 1.8 v power supply for the core and peripherals. this regulator has two different modes: ? main voltage regulator mode (mvr) for run, wait for interrupt (wfi) and wait for event (wfe) modes. ? low power voltage regulator mode (lpvr) for halt, active-halt, low power run and low power wait modes. when entering halt or active -halt modes, the system automatic ally switches from the mvr to the lpvr in order to reduce current consumption. functional overview stm8l151x4/6, stm8l152x4/6 18/142 docid15962 rev 15 3.4 clock management the clock controller distributes the system cloc k (sysclk) 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. ? clock management: to reduce power consumption, th e clock controller can stop the clock to the core, individual peripherals or memory. ? system clock sources: 4 different clock sources can be used to drive the system clock: ? 1-16 mhz high speed external crystal (hse) ? 16 mhz high speed internal rc oscillator (hsi) ? 32.768 khz low speed external crystal (lse) ? 38 khz low speed internal rc (lsi) ? rtc and lcd clock sources: the above four sources can be chosen to clock the rtc and the lcd, whatever the system clock. ? startup clock: after reset, the microcontroller rest arts 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 a hse clock failure occurs, the system clock is automatically switched to hsi. ? configurable main clock output (cco): this outputs an external clock for use by the application. docid15962 rev 15 19/142 stm8l151x4/6, stm8l152x4/6 functional overview 58 figure 2.

sensing functionality to any application. capacitive sensing technology is able to detect finger presence near an electr ode which is protected from direct touch by a dielectric (example, glass, plastic). the capacitive variation introduced by a finger (or any conductive object) is measured using a proven implementation based on a surface charge transfer acquisition principle. it consists of charging the electrode capacitance and then transferring a part of the accumulated char ges into a sampling capacitor until the voltage across this capacitor has reached a specific threshold. in

mode, the interrupt is served if it has been previously enabled. after processing the interrupt, the pr ocessor goes back to wfe mode. when the interrupt is configured as a wakeup event, the cpu wakes up and resumes processing. 2. the interrupt from pvd is logically or-ed with port e and f interrupts. register exti_conf allows to select between port e and port f interrupt (see external interrupt port select register (exti_conf) in the rm0031). 3. the device is woken up from halt or active-halt mode only when the address received matches the interface address. table 11. interrupt mapping

external voltage below v ss or above v dd (for standard 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 acci dentally happens, susceptibility tests are performed on a sample basis during device characterization. functional susceptibility 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, out of spec current injection on adjacent pins or other functional failure (for example reset, oscillator frequency deviation, lcd levels, etc.). the test results are given in the following table. 9.3.7 i/o port pin characteristics general characteristics subject to general

until a functional disturbance occurs. this test conforms with the iec 61000 standard. ? ftb : a burst of fast transient voltage (p ositive and negative) is applied to v dd and v ss through a 100 pf capacitor, until a function al disturbance occurs. this test conforms with the iec 61000 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 per formed at component level with a typical application environment and simplified mcu soft ware. 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 re lation with the emc level requested for his application. prequalification trials most of the common failures (unexpected reset and program counter corruption) can be reproduced by manually forci ng a low state on the nrst pin or the oscillator pins for 1 second. to complete these trials, esd stress can be applie d 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) based on a simple application running on the product (toggling 2 leds through the i/o ports), the product is monitored in terms of em
