Inkcazo
Izixhobo ze-STM32L471xx ziyi-microcontrollers ze-ultra-low-power based on highperformance 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 yokwenziwa kwedatha kunye neendidi zedatha.Ikwasebenzisa isethi epheleleyo yemiyalelo ye-DSP kunye neyunithi yokukhusela imemori (MPU) eyenza ukhuseleko lwesicelo.Izixhobo ze-STM32L471xx zifake iinkumbulo zesantya esiphezulu (imemori ye-Flash ukuya kwi-1 Mbyte, ukuya kwi-128 Kbyte ye-SRAM), umlawuli wememori yangaphandle eguquguqukayo (FSMC) yeenkumbulo ezimileyo (kwizixhobo ezineephakheji ze-100 nezikhonkwane kunye nokunye), i-Quad SPI. ujongano lweenkumbulo ezikhanyayo (ezikhoyo kuzo zonke iipakethe) kunye noluhlu olubanzi lwee-I/Os eziphuculweyo kunye neeperipherals eziqhagamshelwe kwiibhasi ezimbini ze-APB, iibhasi ezimbini ze-AHB kunye ne-32-bit ye-matrix yebhasi ye-AHB emininzi.Izixhobo ze-STM32L471xx zifake iindlela ezininzi zokukhusela kwimemori edibeneyo yeFlash kunye ne-SRAM: ukukhuselwa kokufunda, ukhuseleko lokubhala, ukukhuselwa kwekhowudi yobunikazi kunye ne-Firewall.Izixhobo zibonelela ukuya kuthi ga kwii-ADC ezintathu ezikhawulezayo ze-12-bit (5 Msps), izithelekisi ezimbini, ii-amplifiers ezimbini zokusebenza, iziteshi ezimbini zeDAC, i-internal voltage reference buffer, i-RTC enamandla aphantsi, ezimbini iinjongo eziqhelekileyo ze-32-bit timer, ezimbini ze-16. Izibali-xesha ze-PWM ze-bit ezinikezelwe kulawulo lweemoto, izibali-xesha ezisixhenxe zenjongo eqhelekileyo ye-16-bit, kunye nezibali-xesha ezimbini ze-16-bit zamandla aphantsi.Izixhobo zixhasa iifilitha ezine zedijithali kwiimodyuli zangaphandle ze-sigma delta (DFSDM).
