Bayani

Na'urorin STM32L452xx masu sarrafa ƙananan ƙananan ƙarfi ne bisa babban aikin Arm® Cortex®-M4 32-bit RISC core wanda ke aiki a mitar har zuwa 80 MHz.Cortex-M4 core yana fasalta madaidaicin madaidaicin ruwa (FPU) wanda ke goyan bayan duk umarnin sarrafa bayanai guda ɗaya na Arm® da nau'ikan bayanai.Hakanan yana aiwatar da cikakken saitin umarnin DSP da naúrar kariyar ƙwaƙwalwar ajiya (MPU) wanda ke haɓaka amincin aikace-aikacen.Na'urorin STM32L452xx sun haɗa manyan ƙwaƙwalwar ajiya mai sauri (Ƙwaƙwalwar Flash har zuwa 512 Kbyte, 160 Kbyte na SRAM), ƙa'idar ƙwaƙwalwar Quad SPI Flash (akwai akan duk fakiti) da babban kewayon haɓaka I/Os da na'urori masu alaƙa da bas ɗin APB guda biyu. , motocin bas guda biyu na AHB da matrix na bas mai 32-bit multi-AHB.Na'urorin STM32L452xx sun haɗa hanyoyin kariya da yawa don shigar da ƙwaƙwalwar Flash da SRAM: kariyar karantawa, rubuta kariya, kariyar karanta lambar mallakar mallaka da Firewall.Na'urorin suna ba da ADC mai sauri 12-bit (5 Msps), masu kwatanta guda biyu, amplifier ɗaya mai aiki, tashar DAC ɗaya, buffer na ciki, ƙaramin ƙarfin RTC, maƙasudin maƙasudin 32-bit na lokaci ɗaya, mai ƙidayar PWM 16-bit guda ɗaya. sadaukarwa ga sarrafa mota, maƙasudin maƙasudin 16-bit masu ƙidayar lokaci guda huɗu, da masu ƙidayar ƙarancin ƙarfi 16-bit guda biyu.Bugu da kari, har zuwa tashoshi 21 masu karfin ji suna samuwa.Har ila yau, sun ƙunshi daidaitattun hanyoyin sadarwa na zamani da ci gaba, wato I2C guda huɗu, SPI uku, USARTs uku, UART ɗaya da UART ɗaya mai ƙarancin ƙarfi, SAI ɗaya, SDMMC ɗaya, CAN ɗaya, na'ura mai cikakken sauri na USB ɗaya ƙasa.STM32L452xx yana aiki a cikin -40 zuwa +85 °C (+105 °C junction) da -40 zuwa +125 °C (+130 °C junction) zafin jiki ya tashi daga 1.71 zuwa 3.6 V VDD wutar lantarki lokacin amfani da mai sarrafa LDO na ciki. da wutar lantarki 1.05 zuwa 1.32V VDD12 lokacin amfani da wadatar SMPS na waje.Cikakken saitin hanyoyin ceton wutar lantarki yana ba da damar ƙirar aikace-aikacen ƙarancin ƙarfi.Ana goyan bayan wasu kayan wuta masu zaman kansu: shigarwar wadatar mai zaman kanta ta analog don ADC, DAC, OPAMP da masu kwatance.Shigar da VBAT yana ba da damar yin ajiyar RTC da rijistar madadin.Ana iya amfani da keɓantaccen kayan wuta na VDD12 don ƙetare mai sarrafa LDO na ciki lokacin da aka haɗa su zuwa SMPS na waje.Iyalin STM32L452xx suna ba da fakiti bakwai daga fakiti 48 zuwa 100-pin.
