Izixhobo ze-STM32L451xx zifakela iinkumbulo ezinesantya esiphezulu (inkumbulo yeFlash ukuya kuthi ga kwi-512 Kbyte, 160 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-STM32L451xx zifake iindlela ezininzi zokukhusela kwimemori edibeneyo yeFlash kunye ne-SRAM: ukukhuselwa kokufunda, ukhuseleko lokubhala, ukukhuselwa kwekhowudi yobunikazi kunye ne-Firewall.
Izixhobo zibonelela ngokukhawuleza kwe-12-bit ADC (5 Msps), abathelekisi ababini, iamplifier enye yokusebenza, ishaneli enye yeDAC, i-internal voltage reference buffer, i-RTC enamandla aphantsi, enye injongo ye-32-bit timer, enye i-16-bit. Isibali-xesha se-PWM esinikezelwe kulawulo lweemoto, izibali-xesha ezine zenjongo ngokubanzi ze-16-bit, kunye nezimbini ezine-16-bit zamandla aphantsi.
Ukongeza, ukuya kuthi ga kwi-21 i-capacitive sensing channels ezikhoyo.
Zikwabonisa ujongano olusemgangathweni noluphambili lonxibelelwano, oluzezi I2Cs ezine, ii-SPI ezintathu, ii-USART ezintathu, i-UART enye kunye ne-UART yaMandla aPhantsi enye, i-SAI enye, iSDMMC enye, i-CAN enye.
I-STM32L451xx isebenza kwi -40 ukuya +85 °C (+105 °C isidibaniso) kunye -40 ukuya +125 °C (+130 °C junction) iqondo lobushushu ukusuka kwi-1.71 ukuya kwi-3.6 V yombane.Iseti ebanzi yeendlela zokonga amandla zenza ukuba uyilo lwezicelo zamandla aphantsi.
Ezinye izinikezelo zamandla ezizimeleyo ziyaxhaswa: igalelo lonikezelo oluzimeleyo lwe-analog ye-ADC, iDAC, i-OPAMP kunye nabathelekisi.Igalelo le-VBAT lenza kube lula ukugcina i-RTC kunye neerejista zogcino.
Intsapho ye-STM32L451xx inikezela ngeepakethi ezintandathu ukusuka kwi-48 ukuya kwiipakethi ze-100-pin.
