I-STM32L073V8T6 IC MCU 32BIT 64KB IFLASH 100LQFP

Incazelo

Izilawuli ezincane ze-STM32L073xx ezinamandla aphansi kakhulu zifaka amandla okuxhumana ebhasi le-serial yendawo yonke (i-USB 2.0 crystal-less) enomgogodla osebenza kahle kakhulu we-Arm Cortex-M0+ 32-bit RISC osebenza kumafrikhwensi angama-32 MHz, iyunithi yokuvikela inkumbulo ( I-MPU), izinkumbulo ezishumekwe ngesivinini esiphezulu (kufika ku-192 Kbytes wenkumbulo yohlelo lwe-Flash, ama-Kbytes angu-6 wedatha EEPROM kanye nama-Kbytes angu-20 we-RAM) kanye nohlu olubanzi lwama-I/O nama-peripherals athuthukisiwe.Amadivayisi we-STM32L073xx ahlinzeka ngamandla aphezulu ekusebenzeni okubanzi.Ifinyelelwa ngokukhethwa okukhulu kwemithombo yewashi yangaphakathi nangaphandle, ukulungiswa kwe-voltage yangaphakathi kanye nezindlela ezimbalwa zamandla aphansi.Amadivayisi we-STM32L073xx anikezela ngezici ezimbalwa ze-analog, i-12-bit ADC eyodwa ene-hardware oversampling, ama-DAC amabili, iziqhathaniso ezimbili zamandla aphansi kakhulu, izibali-sikhathi ezimbalwa, isibali-sikhathi esisodwa samandla aphansi (LPTIM), izibali-sikhathi ezine zenhloso ejwayelekile engu-16-bit nezimbili. isibali sikhathi esiyisisekelo, 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-STM32L073xx ashumeka izixhumanisi ezijwayelekile nezithuthukisiwe zokuxhumana: kufika kuma-I2C amathathu, ama-SPI amabili, i-I2S eyodwa, ama-UART amane, i-UART (LPUART) enamandla aphansi, kanye ne-USB engenabucwebe.Amadivayisi anikezela ngamashaneli afinyelela ku-24 e-capacitive ukuze angeze nje ukusebenza kwezinzwa zokuthinta kunoma yiluphi uhlelo lokusebenza.I-STM32L073xx ihlanganisa newashi lesikhathi sangempela kanye nesethi yamarejista ayisipele ahlala esebenza kumodi yokulinda.Okokugcina, isilawuli sazo se-LCD esihlanganisiwe sinejeneretha ye-voltage ye-LCD eyakhelwe ngaphakathi evumela ukushayela kufikela kuma-LCD angama-multiplexed angu-8 ngokungafani okuzimele ku-voltage yokuhlinzeka.Amadivayisi anamandla aphansi kakhulu e-STM32L073xx 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.
