STM32L471RET6 IC MCU 32BIT 512KB FLASH 64LQFP

Ibisobanuro

Ibikoresho bya STM32L471xx ni microcontrollers ya ultra-low-power-power ishingiye kubikorwa byo hejuru cyane Arm® Cortex®-M4 32-bit ya RISC yibanze ikora kuri frequence igera kuri 80 MHz.Cortex-M4 yibanze iranga Floating point unit (FPU) icyerekezo kimwe gishyigikira Arm® imwe-imwe-yamakuru-yo gutunganya amakuru hamwe nubwoko bwamakuru.Irashyira mubikorwa kandi byuzuye amabwiriza ya DSP hamwe nigice cyo kurinda kwibuka (MPU) byongera umutekano wibisabwa.Ibikoresho bya STM32L471xx byinjije ibintu byihuta cyane (Flash yibuka kugeza kuri 1 Mbyte, kugeza kuri 128 Kbyte ya SRAM), igenzura ryoroshye ryo kugenzura ibintu (FSMC) kugirango yibuke neza (kubikoresho bifite paki zipakurura 100 nibindi byinshi), Quad SPI flash yibuka (iboneka kumapaki yose) hamwe nurwego runini rwongerewe I / Os hamwe na periferique ihujwe na bisi ebyiri za APB, bisi ebyiri za AHB na materique ya 32-biti-AHB.Ibikoresho bya STM32L471xx byashyizwemo uburyo bwinshi bwo kurinda ububiko bwa Flash yibitseho na SRAM: kurinda gusoma, kwandika kurinda, kurinda kode yihariye no kurinda Firewall.Ibikoresho bitanga bigera kuri bitatu byihuse 12-biti ya ADC (5 Msps), ibigereranya bibiri, ibyuma bibiri byongera imbaraga, imiyoboro ibiri ya DAC, ibyuma byerekana ingufu za voltage imbere, ingufu nke za RTC, bibiri rusange-bigamije 32-biti, bibiri 16 -ibihe bya PWM byeguriwe kugenzura ibinyabiziga, birindwi rusange-bigamije 16-biti, na bibiri-16-bito-bito.Ibikoresho bishyigikira ibice bine bya sisitemu ya moderi yo hanze ya sigma delta (DFSDM).
