STM32L021D4P6 IC MCU 32BIT 16KB IFLESHI 14TSSOP

Inkcazo

Umgca wokufikelela kwi-ultra-low-power STM32L021x4 usapho lubandakanya ukusebenza okuphezulu kweArm® Cortex®-M0+ 32-bit RISC core esebenza kwi-32 MHz rhoqo, iinkumbulo ezizinziswe ngesantya esiphezulu (16 Kbytes yememori yenkqubo yeFlash, i-512 bytes yedatha. I-EEPROM kunye ne-2 Kbytes ye-RAM) kunye noluhlu olubanzi lwee-I/Os eziphuculweyo kunye neeperipherals.Izixhobo ze-STM32L021x4 zibonelela ngokusebenza kwamandla aphezulu kuluhlu olubanzi lokusebenza.Iphunyezwa ngokhetho olukhulu lwemithombo yewotshi yangaphakathi nangaphandle, ukulungiswa kombane wangaphakathi kunye neendlela ezininzi zamandla aphantsi.Izixhobo ze-STM32L021x4 zibonelela ngeempawu ezininzi ze-analog, enye i-12-bit ADC ene-hardware oversampling, i-ultra-low-power compators ezimbini, i-AES, izibali-xesha ezininzi, isibali-xesha esine-low-power (LPTIM), isibali-xesha se-16-bit esinenjongo ngokubanzi ezintathu, i-RTC enye. kunye ne-SysTick enye enokusetyenziswa njengeziseko zexesha.Zikwabonisa ii-watchdogs ezimbini, i-watchdog enye enewotshi ezimeleyo kunye nekhono lefestile kunye ne-window watchdog enye esekelwe kwiwashi yebhasi.Ngaphezu koko, izixhobo ze-STM32L021x4 zifakela unxibelelwano olusemgangathweni kunye nonxibelelwano oluphambili: i-I2C enye, i-SPI enye, i-USART enye, kunye ne-UART yamandla aphantsi (LPUART).I-STM32L021x4 ikwabandakanya iwotshi yexesha langempela kunye neseti yeerejista zogcino ezihlala zisebenza kwimo yokulinda.Izixhobo ze-STM32L021x4 ze-ultra-low-power zisebenza ukusuka kwi-1.8 ukuya kwi-3.6 V unikezelo lwamandla (ukuhla ukuya kwi-1.65 V kwi-power down) kunye ne-BOR kunye ne-1.65 ukuya kwi-3.6 V unikezelo lwamandla ngaphandle kwe-BOR inketho.Zifumaneka kwi -40 ukuya +125 °C kuluhlu lobushushu.Iseti ebanzi yeendlela zokugcina amandla ivumela ukuyilwa kwezicelo zamandla aphantsi.
