I-STM32L071CBT6 IC MCU 32BIT 128KB IFLASH 48LQFP

Incazelo

Ulayini wokufinyelela we-ultra-low-power STM32L071xx microcontrollers ihlanganisa ukusebenza okuphezulu kwe-Arm Cortex-M0+ 32-bit RISC core esebenza kumafrikhwensi angu-32 MHz, iyunithi yokuvikela inkumbulo (MPU), izinkumbulo ezishumekwe ngesivinini esiphezulu (kufika ku-192 Kbytes wohlelo lwe-Flash. inkumbulo, ama-Kbytes angu-6 edatha ye-EEPROM kanye nama-Kbytes angu-20 we-RAM) kanye nohlu olubanzi lwama-I/O nama-peripheral athuthukisiwe.Amadivayisi we-STM32L071xx ahlinzeka ngamandla aphezulu ekusebenzeni okubanzi.Ifinyelelwa ngokukhethwa okukhulu kwemithombo yewashi yangaphakathi nangaphandle, ukulungiswa kwe-voltage yangaphakathi kanye nezindlela ezimbalwa zamandla aphansi.Amadivayisi we-STM32L071xx anikela ngezici ezimbalwa ze-analog, i-12-bit ADC eyodwa ene-hardware oversampling, iziqhathaniso ezimbili zamandla aphansi kakhulu, izibali-sikhathi ezimbalwa, isibali-sikhathi esisodwa samandla aphansi (LPTIM), izibali-zikhathi ezine zenjongo evamile engu-16-bit kanye nesibali-sikhathi esiyisisekelo esimbili, 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-STM32L071xx ashumeka izixhumanisi ezijwayelekile nezithuthukile zokuxhumana: kufika kuma-I2C amathathu, ama-SPI amabili, i-I2S eyodwa, ama-USART amane, i-UART (LPUART) enamandla aphansi, .I-STM32L071xx ihlanganisa newashi lesikhathi sangempela kanye nesethi yamarejista ayisipele ahlala esebenza kumodi yokulinda.Amadivayisi anamandla aphansi kakhulu e-STM32L071xx asebenza kusukela kumandla kagesi angu-1.8 kuya ku-3.6 V (ehle 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.
