Amadivayisi e-STM32L431xx angama-microcontrollers anamandla aphansi kakhulu asuselwa kumongo we-Arm® Cortex®-M4 32-bit RISC osebenza kakhulu osebenza imvamisa yokufika ku-80 MHz.I-Cortex-M4 core ifaka iyunithi yephoyinti elintantayo (i-FPU) ukunemba okukodwa okusekela yonke imiyalelo ye-Arm® yokunemba okukodwa yokucubungula idatha nezinhlobo zedatha.Iphinde isebenzise isethi egcwele yemiyalelo ye-DSP kanye neyunithi yokuvikela inkumbulo (MPU) ethuthukisa ukuphepha kohlelo lokusebenza.Amadivayisi we-STM32L431xx ashumeka izinkumbulo zesivinini esikhulu (Inkumbulo ye-Flash efika ku-256 Kbyte, 64 Kbyte ye-SRAM), isixhumi esibonakalayo se-Quad SPI memory memory (etholakala kuwo wonke amaphakheji) kanye nohlu olubanzi lwama-I/O athuthukisiwe nama-peripheral axhunywe kumabhasi amabili e-APB , amabhasi amabili e-AHB kanye ne-32-bit multi-AHB matrix yebhasi.Amadivayisi we-STM32L431xx ashumeka izindlela zokuvikela ezimbalwa zememori ye-Flash eshumekiwe kanye ne-SRAM: ukuvikelwa kokufunda, ukuvikelwa kokubhala, ukuvikelwa kokufunda ikhodi yobunikazi kanye ne-Firewall.Amadivayisi anikezela nge-ADC engu-12-bit esheshayo (5 Msps), iziqhathaniso ezimbili, isikhulisi esisodwa sokusebenza, amashaneli e-DAC amabili, isigcinalwazi sereferensi kagesi wangaphakathi, i-RTC enamandla aphansi, isibali sikhathi senhloso eyodwa esingu-32-bit, isibali sikhathi esisodwa esingu-16-bit PWM. okunikezelwe ekulawuleni kwezimoto, izibali sikhathi ezine zenhloso evamile engu-16-bit, nezibali-sikhathi ezimbili zamandla aphansi angu-16-bit.Ngaphezu kwalokho, kuze kufike kumashaneli angama-21 e-capacitive ayatholakala.Ziphinde zibe nezindawo zokuxhumana ezisezingeni nezithuthukile.• Ama-I2C amathathu • Ama-SPI amathathu • Ama-USART amathathu kanye ne-UART eyodwa Yamandla Aphansi.• I-One SAI (Serial Audio Interfaces) • I-SDMMC Eyodwa • I-CAN I-One SWPMI (I-Single Wire Protocol Master Interface) I-STM32L431xx isebenza ku- -40 kuya ku-+85 °C (+105 °C ukuhlangana), -40 kuya ku-+105 ° I-C (+125 °C junction) kanye -40 kuya ku-+125 °C (+130 °C junction) isukela ku-1.71 kuya ku-3.6 V kagesi.Isethi ephelele yamamodi okonga amandla ivumela ukuklanywa kwezinhlelo zokusebenza zamandla amancane.Ezinye izinsiza zamandla ezizimele ziyasekelwa: okokufaka okuzimele kwe-analog kwe-ADC, i-DAC, i-OPAMP neziqhathanisi.Okokufaka kwe-VBAT kuvumela ukwenza isipele i-RTC namarejista ayisipele.Umndeni we-STM32L431xx unikeza amaphakheji ayisishiyagalolunye ukusuka kumaphakheji angama-32 kuye kwayi-100-pin.
