♠ Ultra-power-power Arm® Cortex®-M4 32-bit MCU + FPU, 100DMIPS, kugeza 1MB Flash, 128 KB SRAM, USB OTG FS, LCD, umugereka. SMPS
Ibikoresho bya STM32L476xx ni microcontrollers ya ultra-low-power-power ishingiye cyane kuri Arm® Cortex®-M4 32-bit ya RISC yibanze ikora kuri frequence ya 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 STM32L476xx byashyizwemo kwibuka byihuse (Flash yibuka kugeza kuri 1 Mbyte, kugeza kuri 128 Kbyte ya SRAM), igenzura ryoroshye ryo kugenzura ibintu (FSMC) kugirango yibuke ibintu bihamye (kubikoresho bifite paki zipakurura 100 nibindi byinshi), interineti ya Quad SPI flash yibuka (iboneka kumapaki yose) hamwe na bisi ebyiri za ABB hamwe na bisi ebyiri za ABB.
Ibikoresho bya STM32L476xx byashyizwemo uburyo bwinshi bwo kurinda ububiko bwa Flash yibitseho na SRAM: kurinda gusoma, kwandika kurinda, kurinda kode yihariye yo gusoma hamwe na Firewall.
Ibikoresho bitanga bigera kuri bitatu byihuse 12-biti ya ADC (5 Msps), ibigereranya bibiri, ibyuma byongera imbaraga, imiyoboro ibiri ya DAC, ibyuma byerekana ingufu za interineti imbere, ingufu nke za RTC, ibyerekezo rusange-32-biti, bibiri bya 16-biti bya PWM byeguriwe kugenzura ibinyabiziga, birindwi-bigamije 16-biti, na bibiri-16-bito-bito. Ibikoresho bishyigikira ibice bine bya sisitemu ya moderi yo hanze ya sigma delta (DFSDM).
