♠ 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 ashumeke izinkumbulo zesivinini esikhulu (Inkumbulo ye-Flash efika ku-1 Mbyte, ifika ku-128 Kbyte ye-SRAM), isilawuli sememori yangaphandle esiguqukayo (FSMC) sezinkumbulo ezimile (kumadivayisi anamaphakeji amaphini angu-100 nokunye), i-Quad SPI. isixhumi esibonakalayo sezinkumbulo ezikhanyayo (esitholakala kuwo wonke amaphakheji) kanye nohlu olubanzi lwama-I/O nama-peripheral athuthukisiwe axhunywe kumabhasi amabili e-APB, amabhasi amabili e-AHB kanye ne-32-bit ye-multi-AHB yebhasi matrix.

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 anikela ngama-ADC amathathu asheshayo e-12-bit (5 Msps), iziqhathaniso ezimbili, izikhulisa-zwi ezimbili ezisebenzayo, iziteshi ezimbili ze-DAC, isigcinalwazi sereferensi kagesi wangaphakathi, i-RTC enamandla aphansi, isibali sikhathi senhloso ejwayelekile engu-32-bit, ezimbili eziyi-16. -Izibali sikhathi ze-PWM ezincanyana ezinikelwe ekulawuleni izithuthuthu, izibali sikhathi eziyisikhombisa zenhloso evamile engu-16-bit, nezibali-sikhathi ezimbili ze-16-bit zamandla aphansi.Amadivayisi asekela izihlungi ezine zedijithali ze-sigma delta modulators yangaphandle (DFSDM).
