Idatha ye-STM32L053R8T6TR IC MCU 32BIT 64KB IFLASH 64LQFP

Incazelo

Ama-microcontrollers anamandla aphansi kakhulu e-STM32L053x6/8 ahlanganisa 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, ukuvikela inkumbulo. iyunithi (MPU), izinkumbulo ezishumekwe ngesivinini esiphezulu (kufika ku-64 Kbytes wenkumbulo yohlelo lwe-Flash, ama-Kbytes angu-2 wedatha ye-EEPROM kanye no-8 Kbytes we-RAM) kanye nobubanzi obubanzi be-I/Os nama-peripherals athuthukisiwe.Amadivayisi we-STM32L053x6/8 ahlinzeka ngokusebenza kahle kwamandla okubanzi kokusebenza okubanzi.Ifinyelelwa ngokukhethwa okukhulu kwemithombo yewashi yangaphakathi nangaphandle, ukulungiswa kwe-voltage yangaphakathi kanye nezindlela ezimbalwa zamandla aphansi.Amadivayisi we-STM32L053x6/8 anikezela ngezici ezimbalwa ze-analog, i-12-bit ADC eyodwa ene-hardware oversampling, i-DAC eyodwa, iziqhathaniso ezimbili zamandla aphansi kakhulu, izibali sikhathi ezimbalwa, isibali-sikhathi esisodwa samandla aphansi (LPTIM), izibali-sikhathi ezintathu zenhloso evamile engu-16-bit. kanye nesibali-sikhathi esisodwa 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-STM32L053x6/8 ashumeka izixhumanisi zokuxhumana ezisezingeni nezithuthukisiwe: kufika kuma-I2C amabili, ama-SPI amabili, i-I2S eyodwa, ama-USART amabili, 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-STM32L053x6/8 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-STM32L053x6/8 asebenza kusukela kumandla kagesi angu-1.8 kuya ku-3.6 V (ehle aze afike ku-1.65 V lapho amandla ephansi) nge-BOR futhi asuka 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.
