STM32L452CEU6 IC MCU 32BIT 512KB IFLESHI 48UFQFPN

Inkcazo

Izixhobo ze-STM32L452xx 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-STM32L452xx 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-STM32L452xx zifake iindlela ezininzi zokukhusela kwimemori edibeneyo yeFlash kunye ne-SRAM: ukhuseleko lokufunda, ukhuseleko lokubhala, ukukhuselwa kwekhowudi yobunikazi kunye ne-Firewall.Izixhobo zibonelela nge-12-bit ADC ekhawulezayo (i-5 Msps), izithelekisi ezimbini, iamplifier enye yokusebenza, itshaneli enye yeDAC, 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 ujongano lonxibelelwano olusemgangathweni noluphambili, oluzezi I2Cs ezine, ii-SPI ezintathu, ii-USART ezintathu, i-UART enye kunye ne-UART enye ye-Low-Power, i-SAI enye, i-SDMMC enye, i-CAN enye, i-USB enye i-full-speed device icrystal ngaphantsi.I-STM32L452xx 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-1.05 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, iDAC, i-OPAMP kunye nabathelekisi.Igalelo le-VBAT lenza ukuba kube lula ukugcina i-RTC kunye neerejista zokulondoloza.Ukunikezelwa kwamandla okuzinikezele kwe-VDD12 kungasetyenziselwa ukudlula umlawuli wangaphakathi we-LDO xa uqhagamshelwe kwi-SMPS yangaphandle.Intsapho ye-STM32L452xx inika iipakethi ezisixhenxe ukusuka kwi-48 ukuya kwi-100-pin.
