Kev piav qhia
Lub ultra-low-power STM32L072xx microcontrollers suav nrog lub zog sib txuas ntawm lub tsheb npav universal serial (USB 2.0 siv lead ua-tsawg) nrog kev ua haujlwm siab Arm Cortex-M0+ 32-ntsis RISC core ua haujlwm ntawm 32 MHz zaus, lub cim xeeb tiv thaiv ( MPU), kev kub ceev embedded nco (txog 192 Kbytes ntawm Flash program nco, 6 Kbytes ntawm cov ntaub ntawv EEPROM thiab 20 Kbytes ntawm RAM) ntxiv rau ntau yam kev txhim kho I/Os thiab cov khoom siv peripherals.Cov khoom siv STM32L072xx muab lub zog ua haujlwm siab rau ntau yam kev ua haujlwm.Nws yog ua tiav nrog kev xaiv loj ntawm lub moos sab hauv thiab sab nraud, kev hloov pauv hauv qhov hluav taws xob thiab ntau hom kev siv hluav taws xob tsawg.Cov khoom siv STM32L072xx muaj ntau yam analogues, ib qho 12-ntsis ADC nrog kho vajtse oversampling, ob lub DACs, ob lub zog qis zog sib piv, ob peb lub sijhawm, ib lub sijhawm qis zog (LPTIM), plaub lub hom phiaj 16-ntsis timers thiab ob yooj yim timer, ib RTC thiab ib SysTick uas yuav siv tau raws li timebases.Lawv kuj muaj ob tus neeg saib xyuas, ib tus saib xyuas nrog lub moos ywj pheej thiab lub qhov rais muaj peev xwm thiab ib lub qhov rais saib xyuas raws li lub tsheb npav.Ntxiv mus, cov khoom siv STM32L072xx embed standard thiab advanced kev sib txuas lus interfaces: mus txog peb I2Cs, ob SPIs, ib tug I2S, plaub UARTs, ib tug tsawg-power UART (LPUART), thiab ib tug crystal-tsawg USB.Cov cuab yeej muaj txog li 24 lub peev xwm ntsuas qhov kev sib txuas kom yooj yim ntxiv cov kev paub txog kev ua haujlwm rau txhua daim ntawv thov.STM32L072xx kuj tseem suav nrog lub sijhawm tiag tiag thiab cov txheej txheem ntawm kev sau npe rov qab uas tseem muaj zog hauv Standby hom.Cov khoom siv ultra-low-power STM32L072xx 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 qhov kub ntawm -40 txog +125 ° C.Cov txheej txheem kev txuag hluav taws xob tso cai rau kev tsim cov ntawv siv hluav taws xob tsawg
