ʻO nā polokalamu STM32L433xx nā microcontrollers ultra-low-power e pili ana i ka hana kiʻekiʻe Arm® Cortex®-M4 32-bit RISC core e hana ana ma ke alapine a hiki i 80 MHz.Hōʻike ka Cortex-M4 core i kahi kiko kiko lana (FPU) kikoʻī hoʻokahi 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 STM32L433xx i nā hoʻomanaʻo kiʻekiʻe (Flash memory a hiki i 256 Kbyte, 64 Kbyte o SRAM), kahi Quad SPI Flash hoʻomanaʻo hoʻomanaʻo (loaʻa ma nā pūʻolo āpau) a me kahi ākea o nā I/Os i hoʻonui ʻia a me nā peripheral pili i ʻelua mau pahi APB , ʻelua mau kaʻa kaʻa AHB a me kahi matrix kaʻaahi 32-bit multi-AHB.Hoʻokomo nā mea STM32L433xx 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 kahi wikiwiki 12-bit ADC (5 Msps), ʻelua mea hoʻohālikelike, hoʻokahi mea hoʻonui hana, ʻelua mau kahawai DAC, kahi pahu kuhikuhi voli kūloko, RTC haʻahaʻa haʻahaʻa, hoʻokahi manawa 32-bit kumu nui, hoʻokahi manawa PWM 16-bit. hoʻolaʻa ʻia no ka hoʻokele kaʻa, ʻehā mau manawa 16-bit kumu nui, a me ʻelua mau manawa mana haʻahaʻa 16-bit.Eia kekahi, hiki i ka 21 capacitive sensing channels i loaʻa.Hoʻokomo pū nā mea hana i kahi mea hoʻokele LCD i hoʻohui ʻia 8x40 a i ʻole 4x44, me ka mea hoʻololi hoʻololi i loko.
