I-STM32L053R8T6TR IC MCU 32BIT 64KB IFLASH 64LQFP

Inkcazo

I-ultra-low-low-power STM32L053x6/8 microcontrollers idibanisa amandla oqhagamshelwano lwebhasi ye-serial yendalo yonke (i-USB 2.0 crystal-less) ene-Arm Cortex-M0+ 32-bit ye-RISC engundoqo esebenza kwi-32 MHz rhoqo, ukhuseleko lwememori. iyunithi (MPU), iinkumbulo ezizinziswe ngesantya esiphezulu (ukuya kwi-64 Kbytes yememori yenkqubo yeFlash, i-2 Kbytes yedatha ye-EEPROM kunye ne-8 Kbytes ye-RAM) kunye noluhlu olubanzi lwee-I/Os eziphuculweyo kunye neeperipherals.Izixhobo ze-STM32L053x6/8 zibonelela ngamandla ombane aphezulu kuluhlu olubanzi lokusebenza.Iphunyezwa ngokhetho olukhulu lwemithombo yewotshi yangaphakathi nangaphandle, ukulungiswa kombane wangaphakathi kunye neendlela ezininzi zamandla aphantsi.Izixhobo ze-STM32L053x6/8 zibonelela ngeempawu ezininzi ze-analog, enye i-12-bit ADC ene-hardware oversampling, iDAC enye, izithelekisi ezimbini zamandla asezantsi kakhulu, izibali-xesha ezininzi, isibali-xesha esine-low-power (LPTIM), ezintathu-injongo jikelele-i-16-bit timer. kunye nesibali-xesha esisisiseko, 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-STM32L053x6/8 zifakela unxibelelwano olusemgangathweni kunye nonxibelelwano oluphambili: ukuya kuthi ga kwi-I2C ezimbini, ii-SPI ezimbini, i-I2S enye, ii-USART ezimbini, i-UART enamandla aphantsi (LPUART), kunye ne-crystal-less USB.Izixhobo zibonelela ukuya kuthi ga kwi-24 capacitive sensing channels ukongeza ngokulula ukusebenza kwe-touch sensing kuso nasiphi na isicelo.I-STM32L053x6/8 ikwabandakanya iwotshi yexesha langempela kunye neseti yeerejista zogcino ezihlala zisebenza kwimo yokulinda.Ekugqibeleni, umlawuli wabo we-LCD odibeneyo une-LCD ye-voltage generator eyakhelwe ngaphakathi evumela ukuqhuba ukuya kuthi ga kwi-LCD ephindwe kabini ngokungafaniyo ngaphandle kombane wokubonelela.Izixhobo ze-STM32L053x6/8 ze-ultra-low-power zisebenza ukusuka kwi-1.8 ukuya kwi-3.6 V ukunikezelwa kwamandla (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.
