STM32L496VGT6 IC MCU 32BIT 1MB FLASH 100LQFP

Ibisobanuro

Ibikoresho bya STM32L496xx ni ultrac-power-microcontrollers 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 STM32L496xx byashyizwemo kwibuka byihuse (kugeza kuri 1 Mbyte ya Flash yibuka, 320 Kbyte ya SRAM), ibintu byoroshye byo kugenzura ibintu (FSMC) byoroshye kwibuka (kubikoresho bifite paki zipakurura 100 nibindi byinshi), Flash ya Quad SPI Imigaragarire yo kwibuka (iboneka kumapaki yose) hamwe nurwego runini rwongerewe I / Os hamwe na periferiya ihujwe na bisi ebyiri za APB, bisi ebyiri za AHB na materix ya 32-biti-AHB.Ibikoresho bya STM32L496xx 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 bibiri byongera imbaraga, imiyoboro ibiri ya DAC, ibyuma byerekana ingufu za voltage imbere, ingufu nke za RTC, bibiri rusange-bigamije 32-biti, bibiri 16 -ibihe bya PWM byeguriwe kugenzura ibinyabiziga, birindwi rusange-bigamije 16-biti, na bibiri-16-bito-bito.Ibikoresho bishyigikira ibice bine bya sisitemu ya moderi yo hanze ya sigma delta (DFSDM).Mubyongeyeho, imiyoboro igera kuri 24 ya capacitive sensing irahari.Ibikoresho kandi byashyizwemo umushoferi wa LCD 8x40 cyangwa 4x44, hamwe na intambwe yimbere.Bagaragaza kandi imiyoboro isanzwe itumanaho kandi igezweho, aribyo bine I2Cs, SPI eshatu, USARTs eshatu, UARTs imwe na U-Power nkeya UART, SAI ebyiri, SDMMC imwe, CAN ebyiri, imwe USB OTG yihuta, imwe SWPMI (protocole imwe ya wire master interface), kamera ya kamera hamwe na DMA2D mugenzuzi.STM32L496xx ikorera muri -40 kugeza kuri +85 ° C (ihuriro +105 ° C), -40 kugeza kuri +125 ° C (ihuriro +130 ° C) 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 amwe yigenga arashyigikirwa: analog itanga ibitekerezo byigenga bya ADC, DAC, OPAMPs nabagereranya, 3.3 V byinjijwe kubitangwa kuri USB hamwe na 14 I / Os birashobora gutangwa byigenga kugeza kuri 1.08 V. Kwinjiza VBAT bituma bishoboka ongera usubize RTC hamwe na rejisitiri yububiko.Amashanyarazi yihariye ya VDD12 arashobora gukoreshwa kugirango arengere imbere LDO igenzura iyo ihujwe na SMPS yo hanze.Umuryango wa STM32L496xx utanga paki zirindwi kuva 64-pin kugeza 169-pin.
