stm32l family is pin-to-pin compatible with the general purpose stm32f family. please refer to stm32l15x documentation for more information on these devices. performance all families incorporate highly energy-efficien t cores with both harvar d architecture and pipelined execution: advanced stm8 core fo r stm8l families and arm cortex?-m3 core for stm32l family. in addition specific care for the design architecture has been taken to optimize the ma/dmips and ma/mhz ratios. this allows the ultralow power performance to range from 5 up to 33.3 dmips. shared peripherals stm8l151xx/152xx and stm32l15xx share identical peripherals which ensure a very easy migration from one family to another: analog peripherals: adc1, dac, and comparators comp1/comp2 digital peripherals: rtc and some communication interfaces common system strategy to offer flexibility and opti mize performance, the stm8 l151xx/152xx and stm32l15xx devices use a common architecture: same power supply range from 1.8

stm8l151xx, stm8l152xx functional overview doc id 15962 rev 3 13/109 3.1 low power modes the stm8l15xxx supports five low power modes to achieve the best compromise between low power consumption, short startup time and available wakeup sources: wait mode : cpu clock is stopped, but selected peripherals keep running. an internal or external interrupt or a reset can be used to exit the microcontroller from wait mode (wfe or wfi mode). wait consumption is around 350 a. low power run mode : the cpu and the selected peripherals are running. execution is done from ram with a low speed oscilla tor (lsi or lse). fl ash and data eeprom are stopped and the voltage regulator is configured in ultralow 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 is around 5.4 a (peripherals off). low power wait mode: this mode is entered when executing a wait for event in low power run mode. it is similar to low power 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 generated 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 is around 3 a (peripherals off). 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 with rtc on lsi is 0.9 a. ac tive-halt consumption with rtc on lse is 1 a. halt mode : cpu and peripheral clocks are stopped, the device remains powered on. the wakeup is triggered by an external interrupt or reset. a few peripherals have also a wakeup from halt capability. switching off th e internal reference voltage reduces power consumption. 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 6 s. halt consumption is 400 na. dynamic consumption in run mode is 190 a/mhz. 3.2 central processing unit stm8 3.2.1 advanced stm8 core the 8-bit stm8 core is designed for code efficiency and performance with an harvard architecture and a 3-stage pipeline. 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

controller: nested interrupts with 3 software priority levels 32 interrupt vectors with hardware priority up to 40 external interrupt sources on 11 vectors trap and reset interrupts stm8l151xx, stm8l152xx functional overview doc id 15962 rev 3 15/109 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 ss ; v dd = 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 dd pins, the corresponding ground pin is v ss . 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 dd and v ss , respectively. v ssio ; v ddio = 1.8 to 3.6 v, down to 1.65 v at power down: external power supplies for i/os. v ddio and v ssio must be connected to v dd and v ss , 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) circuitry. 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 through 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 in reset state 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 stm8l15xxx 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 (mv r) 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. functional overview stm8l151xx, stm8l152xx 16/109 doc id 15962 rev 3 when entering halt or active-halt modes, the system automatically switches from the mvr to the lpvr in order to reduce current consumption. 3.4 clock management the clock controller distributes the system clock (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, the 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 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 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 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. stm8l151xx, stm8l152xx functional overview doc id 15962 rev 3 17/109 figure 2. stm8l15x clock tree diagram 3.5 low power real-time clock the real-time clock (rtc) is an independent binary coded decimal (bcd) timer/counter. six byte locations contain the second, minute, hour (12/24 hour), week day, date, month, year, in bcd (binary coded decimal) format. correction for 28, 29 (leap year), 30, and 31 day months are made automatically. it provides a programmable alarm and programmable periodic interrupts with wakeup from halt capability. periodic wakeup

power wait mode is entered when executing a wfe instruction in low power run mode. 2. in wfe mode, this interrupt is served if it has been previ ously enabled. after processing t he interrupt, the processor goes back to wfe mode. when this interrupt is configured as a wakeup event, the cpu wakes up and resumes processing. 3. the interrupt from pvd is logically or-ed with port e and f in terrupts. register exti_conf allows to select between port e and port f interrupt (see external interrupt port sele ct register (exti_conf) in the rm0031). 4. the device is woken up from halt or active-halt mode only when the address received matches the interface address. table 9. interrupt mapping (continued) irq no. source block description wakeup from halt mode wakeup from active-halt

burst of fast transient voltage (positive 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 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 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 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) based on a simple application running on
