♠ Ultra-humilis potentia Arm® Cortex®-M4 32-bit MCU+FPU, 100DMIPS, usque ad 512KB Flash, 160KB SRAM, analog, audio
STM32L451xx cogitationes microcontrolers potentiae ultra-humilis fundatae sunt in summo opere Arm® Cortex®-M4 32 frenum RISC nucleum operantem in frequentia usque ad 80 MHz.Cortex-M4 nucleus notat punctum fluitantis unitatis (FPU) una praecisio quae omnes Arm® una praecisio notitiarum instructionum ac notitiarum generum sustinet.Etiam plena copia mandatorum DSP instrumentorum et unitatis memoriam tutelae (MPU) quae applicationem securitatis auget.
STM32L451xx machinae memoriae infixae sunt (Flash memoria usque ad 512 Kbyte, 160 Kbyte of SRAM), a Quad SPI Mico memorias interfacies (praesto omnibus fasciculis) et ampla ampliatio aucti I/Os ac periphericis duobus APB busibus connexis. duo AHB buses et 32 bis multi- bus matrix AHB.
STM32L451xx machinae complures machinae tutelae infixae sunt pro memoria Flash infixa et SRAM: praesidium readout, praesidium scribe, signum proprietatis legitur tutela et Firewall.
Cogitationes offerunt celeriter 12-bit ADC (5 Msps), comparatores duo, unus amplificator operationalis, unus canalis DAC, internus intentionis quiddam referentia, humili potentia RTC, unum generale propositum 32-bit timer, unum 16 bis. PWM timer dicatus potestate motori, quattuor generales consilii 16-bit timers, et duo 16 frenum humilis potentiam timentes.
Praeterea usque ad 21 canales sentiendi capacitivum praesto sunt.
Vexillum quoque interfaciunt et communicationem provectae faciunt, nempe quattuor I2Cs, tres SPIs, tres USARTs, unum UART et unum UART Belgici, unum SAI, unum SDMMC, unum CAN.
STM32L451xx operatur in -40 ad +85 °C (+105 °C juncturas ) et -40 ad +125 °C (+130 °C connexiones ) temperaturas ab 1.71 ad 3.6 V copiae potentiae.Constitutio comprehensiva modi potentiae salutaris efficit possibilis consilium applicationum humilium potentiarum.
Aliquae potestates independentes subsidia sustentantur: analogorum iuris copia input pro ADC, DAC, OPAMP et comparatoribus.A VBAT input facit ut tergum RTC et registra tergum possibilis sit.
Familia STM32L451xx sex sarcinas ab 48 ad 100 fasciculis clavorum praebet.
