♠ Ultra-power-power Arm® Cortex®-M4 32-bit MCU + FPU, 100DMIPS, kugeza Flash 512KB, 160KB SRAM, analog, amajwi
Ibikoresho bya STM32L451xx ni ultrac-power-microcontrollers ishingiye cyane kubikorwa bya 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 STM32L451xx byashyizwemo kwibuka byihuse (Flash memory igera kuri 512 Kbyte, 160 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 STM32L451xx byashyizemo uburyo bwinshi bwo kurinda ububiko bwa Flash yibitseho na SRAM: kurinda gusoma, kwandika kurinda, kurinda kode yihariye no kurinda Firewall.
Ibikoresho bitanga byihuta 12-biti ADC (5 Msps), ibigereranya bibiri, amplifier imwe ikora, umuyoboro umwe wa DAC, umuyoboro w’imbere wa voltage imbere, ingufu nke za RTC, intego rusange ya 32-bit, igihe kimwe cya 16-biti ya PWM yagenewe kugenzura moteri, bine rusange-bigamije 16-biti, na bibiri-16-bito-bito bito.
Mubyongeyeho, imiyoboro igera kuri 21 ya capacitive sensing irahari.
Bagaragaza kandi interineti isanzwe kandi igezweho itumanaho, aribyo bine I2Cs, SPI eshatu, USARTs eshatu, UART imwe na Power-UART imwe, SAI, SDMMC imwe, CAN.
STM32L451xx ikorera muri -40 kugeza kuri +85 ° C (ihuriro +105 ° C) na -40 kugeza kuri +125 ° C (+130 ° C ihuriro) ubushyuhe buri hagati ya 1.71 na 3.6 V. Igiteranyo cyuzuye cyo kuzigama imbaraga zituma bishoboka igishushanyo mbonera cya porogaramu nkeya.
Amashanyarazi amwe yigenga arashyigikirwa: analog yigenga itanga ADC, DAC, OPAMP nabagereranya. Iyinjizwa rya VBAT rituma bishoboka kugarura RTC no kwandikisha ibitabo.
Umuryango wa STM32L451xx utanga paki esheshatu kuva 48 kugeza 100-pin.
