♠ 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 pakuita kwepamusoro 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 hweakakwidziridzwa I/Os uye maperipheral akabatana nemabhazi maviri eAPB, maviri AHB mabhazi-matrix maviri eAHB2- 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 kukurumidza 12-bit ADC (5 Msps), maviri anoenzanisa, imwe inoshanda amplifier, maviri eDAC chiteshi, yemukati voltage referensi buffer, yakaderera-simba RTC, imwe general-chinangwa 32-bit timer, imwe 16-bit PWM timer yakatsaurirwa kudzora mota, ina general-chinangwa 16-bit timers, uye maviri 16-bit timer-bit.
