STM32L431CBT6 IC MCU 32BIT 128KB FLASH 48LQFP

Tsanangudzo

Iyo STM32L431xx midziyo ndiyo yekupedzisira-yakaderera-simba microcontrollers yakavakirwa pane yakakwirira-performance Arm® Cortex®-M4 32-bit RISC musimboti unoshanda pafrequency inosvika 80 MHz.Iyo Cortex-M4 musimboti inoratidzira Floating point unit (FPU) imwechete chaiyo iyo inotsigira ese Arm® single-chaiyo data-processing mirayiridzo uye data mhando.Iyo inoshandisawo yakazara seti yemirairo yeDSP uye memory kuchengetedza unit (MPU) iyo inosimudzira kuchengetedzwa kwekushandisa.Iyo STM32L431xx midziyo yakamisikidza yakakwira-kumhanya ndangariro (Flash memory inosvika 256 Kbyte, 64 Kbyte yeSRAM), Quad SPI flash memory interface (inowanikwa pamapakeji ese) uye yakawedzera huwandu hweakagadziridzwa I/Os uye maperipheral akabatana nemabhazi maviri eAPB. , mabhazi maviri eAHB uye 32-bit yakawanda-AHB bhazi matrix.Iyo STM32L431xx zvishandiso zvakanyudza akati wandei nzira dzekudzivirira dzakamisikidzwa Flash memory uye SRAM: chengetedzo yekuverenga, kuchengetedzwa kwekunyora, kodhi kodhi yekuverenga chengetedzo uye Firewall.Midziyo iyi inopa inokurumidza 12-bit ADC (5 Msps), maviri anoenzanisa, imwe inoshanda amplifier, maviri DAC chiteshi, yemukati voltage reference buffer, yakaderera-simba RTC, imwe generalpurpose 32-bit timer, imwe 16-bit PWM timer. yakatsaurirwa kukudzora mota, ina general-chinangwa 16-bit timers, uye maviri 16-bit yakaderera-simba nguva.Mukuwedzera, kusvika ku21 capacitive sensing channels dziripo.Iwo zvakare anoratidza akajairwa uye epamberi ekutaurirana ma interfaces.• MaI2C matatu • MaSPI matatu • Matatu UART uye imwe Low-Simba UART.• One SAI (Serial Audio Interfaces) • Imwe SDMMC • Imwe CAN • Imwe SWPMI (Single Wire Protocol Master Interface) Iyo STM32L431xx inoshanda mu -40 kusvika +85 °C (+105 °C junction), -40 kusvika +105 ° C (+125 °C junction) uye -40 kusvika +125 °C (+130 °C junction) tembiricha inotangira pa1.71 kusvika 3.6 V magetsi.Iyo yakazara seti yemamodhi ekuchengetedza simba inobvumira dhizaini yeakaderera-simba maapplication.Mamwe magetsi akazvimiririra anotsigirwa: analogi yakazvimiririra yekuisa yekuisa yeADC, DAC, OPAMP uye vaenzanisi.Kupinza kweVBAT kunobvumira kuchengetedza RTC uye marejista ekuchengetedza.Iyo STM32L431xx mhuri inopa mapakeji mapfumbamwe kubva pamakumi matatu nembiri kusvika zana-pini mapakeji.
