STM32L021D4P6 IC MCU 32BIT 16KB FLASH 14TSOP

Kev piav qhia

Cov kab nkag ultra-low-power STM32L021x4 tsev neeg suav nrog kev ua haujlwm siab Arm® Cortex®-M0+ 32-ntsis RISC core ua haujlwm ntawm 32 MHz zaus, kev kub ceev embedded nco (16 Kbytes ntawm Flash program nco, 512 bytes ntawm cov ntaub ntawv EEPROM thiab 2 Kbytes ntawm RAM) ntxiv rau ntau yam kev txhim kho I/Os thiab cov khoom siv.Cov khoom siv STM32L021x4 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 STM32L021x4 muaj ntau yam analogues, ib qho 12-ntsis ADC nrog kho vajtse oversampling, ob lub ultra-low-power sib piv, AES, ob peb timers, ib tug low-power timer (LPTIM), peb lub hom phiaj 16-ntsis timers, ib RTC thiab ib tug 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 STM32L021x4 tau teeb tsa tus qauv thiab kev sib txuas lus siab heev: ib qho I2C, ib SPI, ib qho USART, thiab lub zog qis UART (LPUART).STM32L021x4 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 STM32L021x4 ua haujlwm los ntawm 1.8 mus rau 3.6 V fais fab mov (qis mus rau 1.65 V ntawm lub zog qis) nrog BOR thiab los ntawm 1.65 rau 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.
