STM32L452CEU6 IC MCU 32BIT 512KB FLASH 48UFQFPN

Ibisobanuro

Ibikoresho bya STM32L452xx ni ultrac-power-microcontrollers ishingiye cyane cyane 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 STM32L452xx 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 periferiya ihuza bisi ebyiri za APB. , bisi ebyiri za AHB hamwe na materix ya 32-biti-AHB.Ibikoresho bya STM32L452xx byashizemo uburyo bwinshi bwo kurinda ububiko bwa Flash yibitseho na SRAM: kurinda gusoma, kwandika kurinda, kurinda kode yihariye no kurinda Firewall.Ibikoresho bitanga byihuse 12-biti ya ADC (5 Msps), igereranya ebyiri, amplifier imwe ikora, umuyoboro umwe wa DAC, umuyoboro wa voltage w'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.Bagaragaza kandi imiyoboro y'itumanaho isanzwe kandi igezweho, aribyo bine I2Cs, SPI eshatu, USARTs eshatu, UART imwe na Power-UART imwe, SAI, SDMMC imwe, CAN imwe, USB USB yihuta cyane igikoresho cyihuta cyane.STM32L452xx 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 LDO imbere. na 1.05 kugeza 1.32V VDD12 itanga amashanyarazi mugihe ukoresheje SMPS yo hanze.Uburyo bwuzuye bwo 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.Amashanyarazi yihariye ya VDD12 arashobora gukoreshwa kugirango arengere imbere LDO igenzura iyo ihujwe na SMPS yo hanze.Umuryango wa STM32L452xx utanga paki zirindwi kuva 48 kugeza 100-pin.
