Inkcazo
Izixhobo ze-STM32L431xx 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-STM32L431xx zifakela iinkumbulo ezinesantya esiphezulu (inkumbulo yeFlash ukuya kuthi ga kwi-256 Kbyte, 64 Kbyte ye-SRAM), i-Quad SPI flash memory interface (ekhoyo kuzo zonke iipakeji) kunye noluhlu olubanzi lwee-I/Os eziphuculweyo kunye neeperipherals eziqhagamshelwe kwiibhasi ezimbini ze-APB. , iibhasi ezimbini ze-AHB kunye ne-32-bit ye-multi-AHB yebhasi ye-matrix.Izixhobo ze-STM32L431xx zifake iindlela ezininzi zokukhusela kwimemori edibeneyo yeFlash kunye ne-SRAM: ukukhuselwa kokufunda, ukhuseleko lokubhala, ukukhuselwa kwekhowudi yobunikazi kunye ne-Firewall.Izixhobo zibonelela nge-12-bit ADC ekhawulezayo (5 Msps), izithelekisi ezimbini, iamplifier enye esebenzayo, amajelo amabini eDAC, i-internal voltage reference buffer, i-RTC enamandla aphantsi, enye injongo jikelele ye-32-bit timer, enye i-16-bit PWM timer. ezinikezelwe kulawulo lweemoto, ezine-injongo jikelele-i-16-bit izibali-xesha, kunye ne-16-bit ezimbini zezibali zamandla aphantsi.Ukongeza, ukuya kuthi ga kwi-21 i-capacitive sensing channels ezikhoyo.Zikwabonisa unxibelelwano olusemgangathweni noluphambili.• Ii-I2C ezintathu • ii-SPI eziNtathu • Ii-UART eziNtathu kunye ne-UART yaMandla aphantsi enye.• I-SAI enye (I-Serial Audio Interfaces) • I-SDMMC enye • Inye i-CAN • i-SWPMI enye (I-Single Wire Protocol Master Interface) I-STM32L431xx isebenza kwi- -40 ukuya +85 °C (+105 °C isidibaniso), -40 ukuya +105 ° I-C (+125 °C isiphambuka) kunye -40 ukuya +125 °C (+130 °C isidibaniso) isukela kwi-1.71 ukuya kwi-3.6 V yombane.Iseti ebanzi yeendlela zokugcina amandla ivumela uyilo lwezicelo zamandla aphantsi.Ezinye izinikezelo zamandla ezizimeleyo ziyaxhaswa: igalelo lonikezelo oluzimeleyo lwe-analog ye-ADC, iDAC, i-OPAMP kunye nabathelekisi.Igalelo le-VBAT livumela ukugcina i-RTC kunye neerejista zokulondoloza.Intsapho ye-STM32L431xx inika iipakethi ezisithoba ukusuka kwi-32 ukuya kwiipakethi ze-100-pin.
