♠ Amandla aphansi kakhulu i-Arm® Cortex®-M4 32-bit MCU+FPU, 100DMIPS, kufika ku-256KB Flash, 64KB SRAM, i-analog, umsindo

Amadivayisi e-STM32L431xx angama-microcontrollers anamandla aphansi kakhulu asuselwa ekusebenzeni okuphezulu komgogodla we-Arm® Cortex®-M4 32-bit RISC 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 ahlinzeka nge-ADC engu-12-bit esheshayo (5 Msps), iziqhathaniso ezimbili, isikhulisi esisodwa sokusebenza, amashaneli e-DAC amabili, isigcinalwazi sereferensi yamandla kagesi yangaphakathi, i-RTC enamandla aphansi, isibali sikhathi senhloso eyodwa esingu-32-bit, esisodwa esingu-16-bit. Isibali sikhathi se-PWM esinikezelwe ekulawuleni kwezimoto, izibali sikhathi ezine zenhloso evamile engu-16-bit, nezibali-sikhathi ezimbili zamandla aphansi angu-16-bit.
