ʻO nā polokalamu STM32L431xx 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.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 STM32L431xx i nā mea hoʻomanaʻo kiʻekiʻe (Flash memory a hiki i 256 Kbyte, 64 Kbyte o SRAM), he Quad SPI flash memory interface (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 STM32L431xx 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.Hāʻawi pū lākou i nā pilina kamaʻilio maʻamau a holomua.• ʻEkolu I2C • ʻEkolu SPI • ʻEkolu USART a me hoʻokahi UART Mana Haʻahaʻa.• Hoʻokahi SAI (Serial Audio Interfaces) • Hoʻokahi SDMMC • Hoʻokahi CAN • Hoʻokahi SWPMI (Single Wire Protocol Master Interface) Ke hana nei ka STM32L431xx ma ka -40 a +85 °C (+105 °C hui), -40 a +105 ° C (+125 °C junction) a me -40 a +125 °C (+130 °C junction) mai ka 1.71 a 3.6 V mana lako.ʻO kahi pūʻulu piha o nā ʻano hoʻopakele mana hiki ke hoʻolālā i nā noi haʻahaʻa.Kākoʻo ʻia kekahi mau lako mana kūʻokoʻa: hoʻokomo kūʻokoʻa kūʻokoʻa analog no ADC, DAC, OPAMP a me nā mea hoʻohālikelike.Hiki i kahi hoʻokomo VBAT ke hoʻopaʻa i ka RTC a me nā papa inoa hoʻopaʻa.Hāʻawi ka ʻohana STM32L431xx i ʻeiwa pūʻolo mai 32 a i 100-pin pūʻolo.
