Incazelo
Amadivayisi we-STM32L443xx ama-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-STM32L443xx ashumeka izinkumbulo zesivinini esikhulu (256 Kbyte of Flash memory, 64 Kbyte of 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-STM32L443xx 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.Amadivayisi aphinde ashumeke umshayeli we-LCD ohlanganisiwe ongu-8x40 noma i-4x44, ene-converter yangaphakathi yokukhuphuka.
