♠ Ultra-power-power Arm® Cortex®-M4 32-bit MCU + FPU, 100DMIPS, igera kuri 128KB Flash, 40KB SRAM, analog, ext. SMPS
Ibikoresho bya STM32L412xx ni microcontrollers ultra-power-power-power ishingiye cyane 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 STM32L412xx byashyizwemo kwibuka byihuse (Flash yibuka igera kuri 128 Kbyte, 40 Kbyte ya SRAM), interineti yibuka ya Quad SPI Flash (iboneka kumapaki yose) hamwe nurwego runini rwa I / Os hamwe na periferique zahujwe na bisi ebyiri za APB, bisi ebyiri za AHB na materique ya 32-biti ya AHB.
Ibikoresho bya STM32L412xx 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 ADC ebyiri yihuta 12-biti (5 Msps), igereranya ebyiri, amplifier imwe ikora, imbaraga nke za RTC, intego rusange-32-biti, imwe ya 16-biti ya PWM yagenewe kugenzura ibinyabiziga, bine rusange-intego-16-bito, na bibiri-16-bito-bito-bito.
Mubyongeyeho, imiyoboro igera kuri 12 ya capacitive sensing irahari.
Bagaragaza kandi interineti isanzwe kandi igezweho itumanaho, aribyo bitatu I2Cs, SPI ebyiri, USARTs imwe na Power-UART imwe, USB imwe yihuta yihuta ya kristu nkeya.
STM32L412xx ikorera muri -40 kugeza kuri +85 ° C (ihuriro +105 ° C) na -40 kugeza kuri +125 ° C (+130 ° C ihuza) ubushyuhe buri hagati ya 1.71 na 3.6 V VDD itanga amashanyarazi mugihe ukoresheje amashanyarazi ya LDO imbere hamwe na 1.00 kugeza 1.32V VDD12 mugihe utanga amashanyarazi yo hanze. Igiteranyo cyuzuye cyo kuzigama imbaraga zituma bishoboka igishushanyo mbonera cya porogaramu nkeya.
Amashanyarazi amwe amwe yigenga arashyigikirwa: analog yigenga yatanzwe kuri ADC, OPAMP no kugereranya. Iyinjizwa rya VBAT rituma bishoboka kugarura RTC no kwandikisha ibitabo. Amashanyarazi yihariye ya VDD12 arashobora gukoreshwa kugirango arengere imbere LDO igenzura iyo ihujwe na SMPS yo hanze.
Umuryango wa STM32L412xx utanga paki esheshatu kuva 32 kugeza 64-pin.
