♠ ʻO Arm® Cortex®-M4 32-bit MCU+FPU, 100DMIPS, a hiki i 256KB Flash, 64KB SRAM, analog, leo
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 i loko, kahi RTC haʻahaʻa, hoʻokahi manawa 32-bit kumu nui, hoʻokahi 16-bit Hoʻolaʻa ʻia ka manawa PWM i ka mana kaʻa, ʻehā mau manawa 16-bit kumu nui, a me ʻelua mau manawa mana haʻahaʻa 16-bit.
