STM32L552ZET6 IC MCU 32BIT 512KB FLASH 144LQFP

Ibisobanuro

Ibikoresho bya STM32L552xx ni umuryango wa microcontrollers ultra-power-power-power (STM32L5 Series) ishingiye kumikorere ikomeye ya Arm® Cortex®-M33 32-bit ya RISC.Bakora kuri frequence ya 110 MHz.Cortex®-M33 yibanze iranga umurongo umwe-wuzuye ureremba-ingingo (FPU), ushyigikira amabwiriza yose ya Arm® imwe-yuzuye yo gutunganya amakuru hamwe nubwoko bwose bwamakuru.Cortex®-M33 yibanze nayo ishyira mubikorwa byuzuye amabwiriza ya DSP (gutunganya ibimenyetso bya digitale) hamwe nigice cyo kurinda kwibuka (MPU) byongera umutekano wa porogaramu.Ibi bikoresho byashyizwemo ibintu byihuta cyane (512 Kbytes ya Flash yibuka na 256 Kbytes ya SRAM), ibintu byoroshye byo kugenzura ibintu (FSMC) byoroshye kwibuka (kubikoresho bifite paki za pin 100 nibindi byinshi), interineti yibuka ya Octo-SPI .Ibikoresho bya STM32L5 bitanga umusingi wumutekano wujuje ibyangombwa byumutekano byizewe (TBSA) biva muri Arm.Bashyizemo ibimenyetso byumutekano bikenewe kugirango bashyire mubikorwa boot itekanye, kubika amakuru neza, kwishyiriraho porogaramu zizewe no kuzamura porogaramu zizewe.Ubuzima bwimikorere bworoshye buracungwa bitewe ninzego nyinshi zo kurinda gusoma.Ibyuma bya Firmware bitandukanya bishyigikirwa bitewe na periferique itekanye, kwibuka hamwe na I / Os, ndetse no kubishobora gushiraho periferiya nibuka nk "amahirwe".Ibikoresho bya STM32L552xx byashyizwemo uburyo bwinshi bwo kurinda ububiko bwa Flash yibitseho na SRAM: kurinda gusoma, kwandika, kurinda, ahantu hizewe kandi hihishe.
