I-STM32L452CEU6 IC MCU 32BIT 512KB IFLASH 48UFQFPN

Incazelo

Amadivayisi e-STM32L452xx 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 e-STM32L452xx ashumeka izinkumbulo zesivinini esikhulu (Inkumbulo ye-Flash efika ku-512 Kbyte, 160 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-STM32L452xx ashumeka izindlela zokuvikela ezimbalwa zememori ye-Flash eshumekiwe kanye ne-SRAM: ukuvikela ukufunda, ukuvikelwa kokubhala, ukuvikelwa kokufunda ikhodi yobunikazi kanye ne-Firewall.Amadivayisi ahlinzeka nge-ADC engu-12-bit esheshayo (5 Msps), iziqhathaniso ezimbili, isikhulisi esisodwa sokusebenza, isiteshi esisodwa se-DAC, isigcinalwazi sereferensi kagesi wangaphakathi, i-RTC enamandla aphansi, isibali sikhathi senhloso eyodwa esingu-32-bit, isibali sikhathi esisodwa esingu-16-bit PWM. okunikezelwe ekulawuleni kwezimoto, izibali sikhathi ezine zenhloso evamile engu-16-bit, nezibali-sikhathi ezimbili zamandla aphansi angu-16-bit.Ngaphezu kwalokho, kuze kufike kumashaneli angama-21 e-capacitive ayatholakala.Ziphinde zibe nezindawo zokuxhumana ezijwayelekile nezithuthukile, okuyi-I2Cs ezine, ama-SPI amathathu, ama-UART amathathu, i-UART eyodwa kanye ne-UART eyodwa Yamandla Aphansi, i-SAI eyodwa, i-SDMMC eyodwa, i-CAN eyodwa, idivayisi eyodwa ye-USB enesivinini esigcwele icwebezela kancane.I-STM32L452xx isebenza ku--40 kuya ku-+85 °C (+105 °C junction) kanye -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.Ezinye izinsiza zamandla ezizimele ziyasekelwa: okokufaka okuzimele kwe-analog kwe-ADC, i-DAC, i-OPAMP neziqhathanisi.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-STM32L452xx unikeza amaphakheji ayisikhombisa ukusuka kumaphakheji angama-48 kuye kwayi-100-pin.
