♠ Amandla aphansi kakhulu i-Arm® Cortex®-M4 32-bit MCU+FPU, 100DMIPS, kufika ku-128KB Flash, 40KB SRAM, analog, ext.I-SMPS
Amadivayisi e-STM32L412xx angama-microcontrollers aphansi kakhulu asuselwa kumongo osebenza kakhulu we-Arm® Cortex®-M4 32-bit RISC osebenza imvamisa yokufika ku-80 MHz.I-Cortex-M4 core ihlanganisa 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-STM32L412xx ashumeka izinkumbulo zesivinini esikhulu (Inkumbulo ye-Flash efika ku-128 Kbyte, 40 Kbyte ye-SRAM), isixhumi esibonakalayo sezinkumbulo ze-Quad SPI Flash (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-STM32L412xx 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-12-bit ADC (5 Msps) amabili asheshayo, iziqhathaniso ezimbili, isikhulisi esisodwa esisebenzayo, i-RTC enamandla aphansi, isibali sikhathi esisodwa senhloso ejwayelekile esingu-32-bit, isibali sikhathi esisodwa se-16-bit PWM esinikezelwe ekulawuleni izimoto, ezine jikelele- inhloso 16-bit izibali sikhathi, kanye 16-bit ezimbili low-power timer.
Ngaphezu kwalokho, kuze kufike kumashaneli ayi-12 e-capacitive sensing ayatholakala.
Ziphinde zibe nezindawo zokuxhumana ezijwayelekile nezithuthukile, okungama-I2C amathathu, ama-SPI amabili, ama-UART amathathu kanye ne-UART eyodwa Yamandla Aphansi, idivayisi eyodwa ye-USB enesivinini esigcwele icwebezela kancane.
I-STM32L412xx isebenza ku--40 kuya ku-+85 °C (+105 °C junction) kanye -40 kuya ku-+125 °C (+130 °C junction) izinga lokushisa lisuka ku-1.71 kuya ku-3.6 VDD kagesi uma usebenzisa isilawuli sangaphakathi se-LDO kanye nogesi ongu-1.00 kuye ku-1.32V VDD12 uma usebenzisa ukunikezwa kwe-SMPS yangaphandle.Isethi ebanzi yamamodi okonga amandla lenza kube khona ukuklanywa kwezinhlelo zokusebenza zamandla aphansi.
Ezinye izinsiza zamandla ezizimele ziyasekelwa: okokufaka okuzimele kwe-analog kwe-ADC, OPAMP kanye nesiqhathanisi.Okokufaka kwe-VBAT kwenza kube nokwenzeka ukwenza isipele i-RTC namarejista ayisipele.Izimpahla zamandla ezinikelwe ze-VDD12 zingasetshenziswa ukudlula isilawuli sangaphakathi se-LDO lapho sixhunywe ku-SMPS yangaphandle.
Umndeni we-STM32L412xx unikeza amaphakheji ayisithupha ukusuka kumaphakheji angama-32 kuya ku-64-pin.
