I-STM32L151RET6 IC MCU 32BIT 512KB IFLASH 64LQFP

Incazelo

Amadivayisi anamandla aphansi kakhulu we-STM32L151xE kanye ne-STM32L152xE ahlanganisa amandla okuxhumana ebhasi le-serial yendawo yonke (i-USB) enomgogodla osebenza kahle kakhulu we-Arm® Cortex®-M3 32-bit RISC osebenza kumafrikhwensi angu-32 MHz (33.3 DMIPS), iyunithi yokuvikela inkumbulo (MPU), izinkumbulo ezishumekiwe zesivinini esiphezulu (Inkumbulo ye-Flash efika ku-512 Kbytes kanye ne-RAM efika ku-80 Kbytes), kanye nohlu olubanzi lwama-I/O athuthukisiwe nama-peripheral axhunywe kumabhasi amabili e-APB.Amadivayisi we-STM32L151xE kanye ne-STM32L152xE anikezela ngezikhulisamandla zokusebenza ezimbili, i-12-bit ADC eyodwa, ama-DAC amabili, iziqhathaniso ezimbili zamandla aphansi kakhulu, isibali sikhathi senjongo eyodwa engu-32-bit, izibali-zikhathi eziyisithupha zenhloso ejwayelekile engu-16 nezibali-zikhathi ezimbili eziyisisekelo, ingasetshenziswa njengesisekelo sesikhathi.Ngaphezu kwalokho, amadivayisi we-STM32L151xE kanye ne-STM32L152xE aqukethe ukuxhumana okujwayelekile nokuthuthukile: kufika kuma-I2C amabili, ama-SPI amathathu, ama-I2S amabili, ama-UART amathathu, ama-UART amabili ne-USB.Amadivayisi e-STM32L151xE kanye ne-STM32L152xE anikela ngamashaneli enzwa angama-34 ukuze angeze nje ukusebenza kwenzwa yokuthinta kunoma yiluphi uhlelo lokusebenza.Zihlanganisa newashi lesikhathi sangempela kanye nesethi yamarejista ayisipele ahlala esebenza kumodi yokulinda.Okokugcina, isilawuli se-LCD esihlanganisiwe (ngaphandle kwamadivayisi we-STM32L151xE) 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 we-STM32L151xE kanye ne-STM32L152xE asebenza kusukela kumandla kagesi angu-1.8 kuya ku-3.6 V (wehle aze afike ku-1.65 V uma ugesi uphansi) nge-BOR futhi ukusuka ku-1.65 kuya ku-3.6 V ugesi ngaphandle kwenketho ye-BOR.Atholakala emazingeni okushisa -40 kuya +85 °C kanye -40 kuya +105 °C.Isethi ephelele yamamodi okonga amandla ivumela ukuklanywa kwezinhlelo zokusebenza zamandla amancane.
