Kev piav qhia
Lub ultra-low-power STM32L151xE thiab STM32L152xE cov khoom siv suav nrog lub zog txuas ntawm lub tsheb npav thoob ntiaj teb (USB) nrog kev ua haujlwm siab Arm® Cortex®-M3 32-ntsis RISC core ua haujlwm ntawm zaus ntawm 32 MHz (33.3 DMIPS), lub cim xeeb tiv thaiv chav (MPU), kev kub ceev embedded nco (Flash nco txog 512 Kbytes thiab RAM txog 80 Kbytes), thiab ntau yam kev txhim kho I/Os thiab peripherals txuas nrog ob lub tsheb npav APB.Cov khoom siv STM32L151xE thiab STM32L152xE muaj ob lub tshuab ua haujlwm ua haujlwm, ib qho 12-ntsis ADC, ob lub DACs, ob lub tshuab hluav taws xob qis qis, ib lub hom phiaj 32-ntsis timer, rau lub hom phiaj 16-ntsis timers thiab ob lub sijhawm pib, uas tuaj yeem siv raws li lub sijhawm.Ntxiv mus, STM32L151xE thiab STM32L152xE cov cuab yeej muaj cov qauv thiab kev sib txuas lus siab heev: mus txog ob I2Cs, peb SPIs, ob I2S, peb USRTs, ob UARTs thiab ib USB.Lub STM32L151xE thiab STM32L152xE cov khoom siv muaj txog 34 lub peev xwm ntsuas qhov ntsuas kom yooj yim ntxiv qhov kov qhov kev paub ua haujlwm rau txhua daim ntawv thov.Lawv kuj suav nrog lub sijhawm ntawm lub sijhawm tiag tiag thiab cov txheej txheem ntawm kev sau npe rov qab uas tseem muaj zog hauv Standby hom.Thaum kawg, kev sib koom ua ke LCD maub los (tshwj tsis yog STM32L151xE li) muaj lub tshuab hluav taws xob LCD built-in uas tso cai rau tsav mus txog 8 qhov sib npaug ntawm LCD nrog qhov sib txawv ntawm cov khoom siv hluav taws xob.Lub ultra-low-power STM32L151xE thiab STM32L152xE cov khoom siv ua haujlwm los ntawm 1.8 mus rau 3.6 V fais fab mov (txog 1.65 V ntawm lub zog qis) nrog BOR thiab los ntawm 1.65 txog 3.6 V fais fab mov yam tsis muaj BOR xaiv.Lawv muaj nyob rau hauv -40 txog +85 ° C thiab -40 txog +105 ° C kub ntau yam.Cov txheej txheem kev txuag hluav taws xob tso cai rau kev tsim cov ntawv siv hluav taws xob tsawg.
