♠ Ultra-humilis potentia Arm® Cortex®-M4 32-bit MCU+FPU, 100DMIPS, usque ad 256KB Flash, 64KB SRAM, analog, audio
STM32L431xx cogitationes sunt microcontrolers potentiae ultra-humilis innituntur summo operando 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 omnia Arm® una praecisio notitiarum instructionum et notitiarum generum sustinet.Etiam plena copia mandatorum DSP instrumentorum et unitatis memoriam tutelae (MPU) quae applicationem securitatis auget.
STM32L431xx machinae memoriae infixae sunt (Flash memory up to 256 Kbyte, 64 Kbyte of SRAM), a Quad SPI mico memorias interfacies (praesto omnibus fasciculis) et ampla ampliatio I/Os et periphericis duobus APB busibus connexis. duo AHB buses et 32 bis multi- bus matrix AHB.
In STM32L431xx machinae complures machinae tutelae infixae sunt ad memoriam Flash infixam et SRAM: praesidium readout, praesidium scribe, signum proprietatis e praesidio et Firewall.
Cogitationes ieiunium 12-bit ADC offerunt (5 Msps), comparatores duo, unus ampliator operationalis, duo canales DAC, internus intentionis quiddam referentia, humili potentia RTC, unum generale propositum 32-bit timor, unus 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.
