♠ I-Ultra-low-power Arm® Cortex®-M4 32-bit MCU+FPU, 100 DMIPS, ukuya kuthi ga kwi-1 MB Flash, 320 KB SRAM, USB OTG FS, isandi, i-SMPS yangaphandle
Izixhobo ze-STM32L496xx ziyi-ultra-low-power microcontrollers ngokusekelwe kwi-high-performance Arm® Cortex®-M4 32-bit RISC core esebenza ngokuphindaphindiweyo ukuya kwi-80 MHz. Undoqo we-Cortex-M4 ubonisa iyunithi ye-Floating point (FPU) echanekileyo enye exhasa yonke imiyalelo ye-Arm® echanekileyo yokucubungula idatha kunye neentlobo zedatha. Ikwasebenzisa isethi epheleleyo yemiyalelo ye-DSP kunye neyunithi yokukhusela imemori (MPU) eyenza ukhuseleko lwesicelo.
Izixhobo ze-STM32L496xx zifakela iinkumbulo ezinesantya esiphezulu (ukuya kwi-1 Mbyte yememori yeFlash, i-320 Kbyte ye-SRAM), isilawuli sememori yangaphandle eguquguqukayo (FSMC) yeenkumbulo ezimileyo (kwizixhobo ezineepakethe ze-100 nezikhonkwane nangaphezulu), i-Quad SPI Flash memory interface (efumaneka kuzo zonke iipakethi ezibanzi ze-O kunye ne-peripheral edibeneyo) Iibhasi ze-APB, iibhasi ezimbini ze-AHB kunye ne-32-bit ye-multi-AHB ye-matrix yebhasi.
Izixhobo ze-STM32L496xx zifake iindlela ezininzi zokukhusela kwimemori edibeneyo yeFlash kunye ne-SRAM: ukukhuselwa kokufunda, ukhuseleko lokubhala, ukukhuselwa kwekhowudi yobunikazi kunye ne-Firewall.
Izixhobo zibonelela ngee-ADC ezintathu ezikhawulezayo ze-12-bit (5 Msps), izithelekisi ezimbini, ii-amplifiers ezimbini zokusebenza, iziteshi ezimbini ze-DAC, i-internal voltage reference buffer, i-RTC enamandla aphantsi, i-32-bit timer, ezimbini ze-16-bit ze-PWM ezinikezelwe kulawulo lweemoto, iinjongo ezisixhenxe eziqhelekileyo ze-16-bit timer-bit 16-bit, kunye ne-16-bit timer. Izixhobo zixhasa iifilitha ezine zedijithali kwiimodyuli zangaphandle ze-sigma delta (DFSDM).
Ukongeza, ukuya kuthi ga kwi-24 i-capacitive sensing channels ezikhoyo. Izixhobo ziphinde zifake umqhubi we-LCD odibeneyo we-8x40 okanye i-4x44, kunye ne-internal step-up converter.
Zikwabonisa ujongano lonxibelelwano olusemgangathweni noluphambili, ezizezi I2Cs ezine, ii-SPI ezintathu, ii-USART ezintathu, ii-UART ezimbini kunye ne-UART enye yaMandla aPhantsi, ii-SAI ezimbini, i-SDMMC enye, ii-CAN ezimbini, i-USB OTG epheleleyo, i-SWPMI enye (ujongano lwe-wire protocol master), ujongano lwekhamera kunye nomlawuli we-DMA2D.
I-STM32L496xx isebenza kwi--40 ukuya + 85 ° C (+105 ° C junction), -40 ukuya +125 ° C (+130 °C junction) iqondo lokushisa ukusuka kwi-1.71 ukuya kwi-3.6 VDD umbane weVDD xa usebenzisa umlawuli wangaphakathi we-LDO kunye ne-1.05 kwi-VDD yangaphandle ye-SM22 unikezelo lwangaphandle. Iseti ebanzi yeendlela zokonga amandla zenza ukuba uyilo lwezicelo zamandla aphantsi.
Ezinye izibonelelo zamandla ezizimeleyo zixhaswa: igalelo lonikezelo oluzimeleyo lwe-analog ye-ADC, i-DAC, i-OPAMPs kunye nabathelekisi, i-3.3 V igalelo lonikezelo olunikezelweyo lwe-USB kunye ne-14 ye-I / Os inokubonelelwa ngokuzimeleyo ukuya kwi-1.08 V. Igalelo le-VBAT lenza ukuba kwenzeke ukugcina i-RTC kunye neerejista zokulondoloza. Ukunikezelwa kwamandla okuzinikezele kwe-VDD12 kungasetyenziselwa ukudlula umlawuli wangaphakathi we-LDO xa uqhagamshelwe kwi-SMPS yangaphandle.
Intsapho ye-STM32L496xx inika iipakethi ezisixhenxe ukusuka kwi-64-pin ukuya kwiipakethi ze-169-pin.
