♠ Amandla aphansi kakhulu i-Arm® Cortex®-M4 32-bit MCU+FPU, 100 DMIPS, kufika ku-1 MB Flash, 320 KB SRAM, USB OTG FS, umsindo, i-SMPS yangaphandle
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 esivumelana nezimo (FSMC) sememori emile (yamadivayisi anamaphakheji amaphini angu-100 nangaphezulu), isixhumi esibonakalayo sezinkumbulo ze-Quad SPI Flash (etholakala kuwo wonke amaphakheji abanzi/Oral axhumene ne-Iphe ethuthukisiwe) Amabhasi e-APB, amabhasi amabili e-AHB kanye ne-32-bit multi-AHB matrix yebhasi.
Amadivayisi we-STM32L496xx ashumeka izindlela zokuvikela ezimbalwa zememori ye-Flash eshumekiwe kanye ne-SRAM: ukuvikela ukufunda, 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).
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-single wire protocol master interface), isixhumi esibonakalayo sekhamera 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 ugesi we-VDD lapho kusetshenziswa isilawuli sangaphakathi se-LDO kanye nesilawuli sikagesi esingu-1.05 kuya ku-VDD sangaphandle esingu-1.32V. Isethi ebanzi yamamodi okonga amandla lenza kube khona ukuklanywa kwezinhlelo zokusebenza zamandla amancane.
Okunye ukunikezwa kwamandla okuzimele kuyasekelwa: okokufaka okuzimele kwe-analog okuhlinzekwayo kwe-ADC, i-DAC, i-OPAMPs neziqhathanisi, okokufaka okunikezelayo okuzinikele okungu-3.3 V kwe-USB futhi kufika ku-14 I/Os kunganikezwa ngokuzimela kuze kufike ku-1.08 V. 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-STM32L496xx unikeza amaphakheji ayisikhombisa ukusuka kumaphakeji angama-64 kuya ku-169-pin.
