♠ Amandla aphansi kakhulu i-Arm® Cortex®-M4 32-bit MCU+FPU, 100DMIPS, kufika ku-1MB Flash, 128 KB SRAM, USB OTG FS, LCD, ext. I-SMPS
Amadivayisi we-STM32L476xx ama-microcontrollers anamandla aphansi kakhulu asuselwa kumongo osebenza kakhulu 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-STM32L476xx ashumeka izinkumbulo zesivinini esikhulu (Inkumbulo ye-Flash efika ku-1 Mbyte, ifinyelela ku-128 Kbyte ye-SRAM), isilawuli sememori yangaphandle esiguqukayo (FSMC) sememori emile (yamadivayisi anamaphakheji amaphini angu-100 nokuningi), isixhumi esibonakalayo se-Quad SPI sezinkumbulo (esitholakala kuwo wonke amaphakheji abanzi/O axhunyiwe) amabhasi amabili e-APB, amabhasi amabili e-AHB kanye ne-32-bit multi-AHB matrix yebhasi.
Amadivayisi we-STM32L476xx ashumeka izindlela zokuvikela ezimbalwa zememori ye-Flash eshumekiwe kanye ne-SRAM: ukuvikelwa kokufunda, ukuvikelwa kokubhala, ukuvikelwa kokufunda ikhodi yobunikazi kanye ne-Firewall.
Amadivayisi anikezela ngama-ADC amathathu asheshayo we-12-bit (5 Msps), iziqhathaniso ezimbili, izikhulisamandla ezimbili zokusebenza, iziteshi ezimbili ze-DAC, isigcinalwazi sereferensi kagesi wangaphakathi, i-RTC enamandla aphansi, isibali sikhathi senhloso evamile engu-32-bit, izibali-sikhathi ezimbili ze-16-bit PWM ezinikezelwe ekulawuleni imoto, izibali-sikhathi zamandla ayisikhombisa eziyi-16-bit 1 kanye nezibali-sikhathi zamandla aphansi angu-16-bit. Amadivayisi asekela izihlungi ezine zedijithali ze-sigma delta modulators yangaphandle (DFSDM).
