♠ I-Ultra-low-power Arm® Cortex®-M4 32-bit MCU+FPU, 100DMIPS, ukuya kuthi ga kwi-128KB Flash, 40KB SRAM, analog, ext.I-SMPS
Izixhobo ze-STM32L412xx 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-STM32L412xx zifakela iinkumbulo ezinesantya esiphezulu (inkumbulo yeFlash ukuya kuthi ga kwi-128 Kbyte, 40 Kbyte ye-SRAM), i-Quad SPI Flash memory interface (ekhoyo 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-multi-AHB yebhasi ye-matrix.
Izixhobo ze-STM32L412xx zifake iindlela ezininzi zokukhusela kwimemori edibeneyo yeFlash kunye ne-SRAM: ukukhuselwa kokufunda, ukhuseleko lokubhala, ukukhuselwa kwekhowudi yobunikazi kunye ne-Firewall.
Izixhobo zibonelela ezimbini ezikhawulezayo ze-12-bit ADC (5 Msps), izithelekisi ezimbini, iamplifier enye esebenzayo, i-RTC yamandla aphantsi, enye injongo jikelele-32-bit timer, enye i-16-bit PWM timer enikezelwe kulawulo lwemoto, ezine jikelele- Injongo ye-16-bit timers, kunye nezimbini ze-16-bit ezisezantsi zamandla.
Ukongeza, ukuya kuthi ga kwi-12 i-capacitive sensing channels ezikhoyo.
Zikwabonisa ujongano olusemgangathweni noluphambili lonxibelelwano, oluzezi, ii-I2Cs ezintathu, ii-SPI ezimbini, ii-USART ezintathu kunye ne-UART yaMandla aPhantsi enye, isixhobo esinye se-USB esinesantya esipheleleyo sekristale esingaphantsi.
I-STM32L412xx isebenza kwi -40 ukuya +85 °C (+105 °C junction) kunye -40 ukuya +125 °C (+130 °C junction) ukusuka kwi-1.71 ukuya kwi-3.6 VDD umbane weVDD xa usebenzisa umlawuli wangaphakathi we-LDO kunye ne-1.00 ukuya kwi-1.32V VDD12 umbane xa usebenzisa unikezelo lwangaphandle lwe-SMPS.Iseti ebanzi yeendlela zokonga amandla zenza ukuba uyilo lwezicelo zamandla aphantsi.
Ezinye izinikezelo zamandla ezizimeleyo ziyaxhaswa: igalelo lonikezelo oluzimeleyo lwe-analog ye-ADC, OPAMP kunye nesithelekisi.Igalelo le-VBAT lenza kube lula ukugcina i-RTC kunye neerejista zogcino.Ukunikezelwa kwamandla okuzinikezele kwe-VDD12 kungasetyenziselwa ukudlula umlawuli wangaphakathi we-LDO xa uqhagamshelwe kwi-SMPS yangaphandle.
Intsapho ye-STM32L412xx inika iipakethi ezintandathu ukusuka kwi-32 ukuya kwi-64-pin package.
