ʻO nā polokalamu STM32L475xx nā microcontrollers ultra-low-power e pili ana i ka kiʻekiʻe Arm® Cortex®-M4 32-bit RISC core e hana ana ma ke alapine a hiki i 80 MHz.Hāʻawi ka Cortex-M4 core i kahi kikoʻī Floating point unit (FPU) e kākoʻo ana i nā ʻōlelo aʻoaʻo a me nā ʻano ʻikepili āpau o Arm®.Hoʻokomo pū ia i kahi pūʻulu piha o nā ʻōlelo aʻoaʻo DSP a me kahi ʻāpana pale hoʻomanaʻo (MPU) e hoʻonui ai i ka palekana noi.Hoʻokomo nā mea STM32L475xx i nā mea hoʻomanaʻo kiʻekiʻe (Flash memory a hiki i 1 Mbyte, a hiki i 128 Kbyte o SRAM), kahi mea hoʻomanaʻo hoʻomanaʻo waho maʻalahi (FSMC) no nā hoʻomanaʻo paʻa (no nā mea me ka 100 pins package), kahi pānaʻi hoʻomanaʻo uila Quad SPI (loaʻa ma nā pūʻolo a pau) a me ka laulā nui o nā I/Os i hoʻonui ʻia a me nā peripheral i hoʻopili ʻia i ʻelua mau kaʻa APB, ʻelua mau pahi AHB a me kahi 32-bit multi-AHB matrix.Hoʻokomo nā mea STM32L475xx i kekahi mau mea pale no ka hoʻomanaʻo Flash i hoʻokomo ʻia a me SRAM: pale heluhelu, pale kākau, pale helu helu helu proprietary a me Firewall.Hāʻawi nā hāmeʻa i ʻekolu wikiwiki 12-bit ADCs (5 Msps), ʻelua mea hoʻohālikelike, ʻelua mau mea hoʻonui hana, ʻelua mau kahawai DAC, kahi pahu kuhikuhi voli kūloko, kahi RTC haʻahaʻa haʻahaʻa, ʻelua manawa 32-bit kumu nui, ʻelua 16 -bit PWM timers i hoʻolaʻa ʻia i ka mana kaʻa, ʻehiku mau manawa 16-bit kumu nui, a me ʻelua mau manawa mana haʻahaʻa 16-bit.Kākoʻo nā mea hana i nā kānana kikohoʻe ʻehā no nā modulators delta sigma waho (DFSDM).
