STM32L431CBT6 IC MCU 32BIT 128KB FLASH 48LQFP

Ibisobanuro

Ibikoresho bya STM32L431xx ni microcontrollers ya ultra-power-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 STM32L431xx byashyizwemo kwibuka byihuse (Flash yibuka igera kuri 256 Kbyte, 64 Kbyte ya SRAM), interineti yibuka ya Quad SPI (iboneka kumapaki yose) hamwe nurwego runini rwa I / Os hamwe na periferiya ihuza bisi ebyiri za APB. , bisi ebyiri za AHB hamwe na materix ya 32-biti-AHB.Ibikoresho bya STM32L431xx byashyizwemo uburyo bwinshi bwo kurinda ibikoresho bya Flash yibitseho na SRAM: kurinda gusoma, kwandika kurinda, kurinda kode yihariye hamwe na Firewall.Ibikoresho bitanga ADC yihuta 12-biti (5 Msps), igereranya ebyiri, amplifier imwe ikora, imiyoboro ibiri ya DAC, ibyuma byerekana ingufu za voltage imbere, ingufu nke za RTC, rusange rusange-32-biti, imwe ya 16-biti ya PWM byeguriwe kugenzura moteri, bine rusange-intego-16-biti, na bibiri-16-bito-by-imbaraga.Mubyongeyeho, imiyoboro igera kuri 21 ya capacitive sensing irahari.Biranga kandi imiyoboro isanzwe itumanaho.• I2Cs eshatu • SPI eshatu • USARTs eshatu na UART ifite imbaraga nke.• SAI imwe (Serial Audio Interface) • SDMMC imwe • ISHOBORA KUMWE • SWPMI imwe (Imigozi imwe ya porotokole imwe ya interineti) STM32L431xx ikorera muri -40 kugeza kuri +85 ° C (+105 ° C ihuza), -40 kugeza +105 ° C (+125 ° C ihuriro) na -40 kugeza +125 ° C (+130 ° C ihuriro) ubushyuhe buri hagati ya 1.71 na 3.6 V.Uburyo bwuzuye bwo kuzigama imbaraga butuma igishushanyo mbonera cyingufu zikoreshwa.Amashanyarazi amwe yigenga arashyigikirwa: analog yigenga itanga ADC, DAC, OPAMP nabagereranya.Iyinjiza rya VBAT ryemerera kubika RTC no kwandikisha ibitabo.Umuryango wa STM32L431xx utanga ibipapuro icyenda kuva 32 kugeza 100-pin.
