♠ Ultra-low-power Arm® Cortex®-M4 32-bit MCU+FPU, 100DMIPS, kusvika 256KB Flash, 64KB SRAM, analogi, odhiyo

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, mbiri DAC chiteshi, yemukati voltage reference buffer, yakaderera-simba RTC, imwe general-chinangwa 32-bit timer, imwe 16-bit. PWM timer yakatsaurirwa kudzora mota, ina general-chinangwa 16-bit timer, uye maviri 16-bit yakaderera-simba nguva.

Mukuwedzera, kusvika ku21 capacitive sensing channels dziripo.
