I-STM32L021D4P6 IC MCU 32BIT 16KB IFLASH 14TSSOP

Incazelo

Umndeni wokufinyelela we-ultra-low-power STM32L021x4 uhlanganisa ukusebenza okuphezulu kwe-Arm® Cortex®-M0+ 32-bit RISC core esebenza kumafrikhwensi angu-32 MHz, izinkumbulo ezishumekwe ngesivinini esiphezulu (16 Kbytes wememori yohlelo lwe-Flash, amabhayithi angu-512 wedatha. I-EEPROM kanye nama-Kbytes angu-2 we-RAM) kanye nohlu olubanzi lwama-I/O nama-peripherals athuthukisiwe.Amadivayisi we-STM32L021x4 ahlinzeka ngamandla aphezulu ekusebenzeni okubanzi.Ifinyelelwa ngokukhethwa okukhulu kwemithombo yewashi yangaphakathi nangaphandle, ukulungiswa kwe-voltage yangaphakathi kanye nezindlela ezimbalwa zamandla aphansi.Amadivayisi we-STM32L021x4 anikezela ngezici ezimbalwa ze-analog, i-12-bit ADC eyodwa ene-hardware oversampling, iziqhathaniso ezimbili zamandla aphansi kakhulu, i-AES, izibali sikhathi ezimbalwa, isibali-sikhathi esisodwa samandla aphansi (LPTIM), izibali-sikhathi ezintathu zenhloso ejwayelekile engu-16-bit, i-RTC eyodwa. kanye ne-SysTick eyodwa engasetshenziswa njengezisekelo zesikhathi.Baphinde bafake nezinja ezimbili zokubuka, inja eyodwa yokubuka enewashi elizimele namandla ewindi kanye ne-watchdog eyodwa yewindi esekelwe ewashi lebhasi.Ngaphezu kwalokho, amadivayisi we-STM32L021x4 ashumeka izixhumanisi zokuxhumana ezisezingeni nezithuthukisiwe: i-I2C eyodwa, i-SPI eyodwa, i-USART eyodwa, kanye ne-UART (LPUART) enamandla aphansi.I-STM32L021x4 ihlanganisa newashi lesikhathi sangempela kanye nesethi yamarejista ayisipele ahlala esebenza kumodi yokulinda.Amadivayisi anamandla aphansi kakhulu e-STM32L021x4 asebenza kusukela kumandla kagesi angu-1.8 kuya ku-3.6 V (wehle aze afike ku-1.65 V lapho ugesi uphansi) nge-BOR kanye nokusuka ku-1.65 kuya ku-3.6 V kagesi ngaphandle kwenketho ye-BOR.Atholakala ebangeni lokushisa -40 kuya +125 °C.Isethi ebanzi yamamodi okonga amandla ivumela ukuklanywa kwezinhlelo zokusebenza zamandla aphansi.
