I-STM32L496VGT6 IC MCU 32BIT 1MB IFLASH 100LQFP

Incazelo

Amadivayisi we-STM32L496xx angama-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 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-STM32L496xx ashumeka izinkumbulo zesivinini esikhulu (kufika ku-1 Mbyte yememori ye-Flash, 320 Kbyte ye-SRAM), isilawuli sememori sangaphandle esiguqukayo (FSMC) sezinkumbulo ezimile (kumadivayisi anamaphakheji angu-100 amaphini nokunye), i-Quad SPI Flash isixhumi esibonakalayo sezinkumbulo (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-STM32L496xx 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).Ngaphezu kwalokho, kuze kufike kumashaneli angama-24 e-capacitive ayatholakala.Amadivayisi aphinde ashumeke umshayeli we-LCD ohlanganisiwe ongu-8x40 noma i-4x44, ene-converter yangaphakathi yokukhuphuka.Ziphinde zibe nezindawo zokuxhumana ezijwayelekile nezithuthukile, okuyi-I2Cs ezine, ama-SPI amathathu, ama-UART amathathu, ama-UART amabili kanye ne-Low-Power UART eyodwa, ama-SAI amabili, i-SDMMC eyodwa, ama-CAN amabili, i-USB OTG egcwele isivinini, i-SWPMI eyodwa (i-protocol yocingo olulodwa. master interface), isikhombikubona sekhamera kanye nesilawuli se-DMA2D.I-STM32L496xx isebenza ku--40 kuya ku-+85 °C (+105 °C junction), -40 kuya ku-+125 °C (+130 °C junction) izinga lokushisa lisukela ku-1.71 kuya ku-3.6 VDD kagesi lapho usebenzisa isilawuli sangaphakathi se-LDO kanye nogesi ongu-1.05 kuye ku-1.32V VDD12 uma usebenzisa ukunikezwa kwe-SMPS yangaphandle.Isethi ebanzi yamamodi okonga amandla lenza kube khona ukuklanywa kwezinhlelo zokusebenza zamandla amancane.Okunye ukunikezwa kwamandla okuzimele kuyasekelwa: okokufaka okuzimele kwe-analog kwe-ADC, i-DAC, i-OPAMPs neziqhathanisi, okokufaka okunikezelayo okuzinikele okungu-3.3 V kwe-USB futhi kufika ku-14 I/Os kungahlinzekwa ngokuzimela kuze kufike ku-1.08 V. Okokufaka kwe-VBAT kwenza kube nokwenzeka gcina i-RTC namarejista ayisipele.Izimpahla zamandla ezinikelwe ze-VDD12 zingasetshenziswa ukudlula isilawuli sangaphakathi se-LDO lapho sixhunywe ku-SMPS yangaphandle.Umndeni we-STM32L496xx unikeza amaphakheji ayisikhombisa ukusuka kumaphakeji angama-64 kuya ku-169-pin.
