Midziyo yeSTM32L412xx ndeye Ultra-low-power 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 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 STM32L412xx midziyo yakamisikidza yakakwira-kumhanya ndangariro (Flash memory inosvika 128 Kbyte, 40 Kbyte yeSRAM), Quad SPI Flash memory interface (inowanikwa pamapakeji ese) uye huwandu hwakakura hweakakwidziridzwa I/Os uye maperipheral akabatana nemabhazi maviri eAPB. , mabhazi maviri eAHB uye 32-bit yakawanda-AHB bhazi matrix.
Iyo STM32L412xx zvishandiso zvakanyudza akati wandei nzira dzekudzivirira dzakamisikidzwa Flash memory uye SRAM: chengetedzo yekuverenga, kuchengetedzwa kwekunyora, kodhi kodhi yekuverenga chengetedzo uye Firewall.
Zvishandiso izvi zvinopa maviri anokurumidza 12-bit ADC (5 Msps), maviri anoenzanisa, imwe inoshanda amplifier, 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 yakaderera-simba nguva.
Mukuwedzera, kusvika ku12 capacitive sensing channels dziripo.
Iwo zvakare anoratidza akajairwa uye epamberi kutaurirana machinjiro, anoti I2Cs matatu, maviri SPIs, matatu UARTs uye imwe Yakaderera-Simba UART, imwe USB yakazara-kumhanya mudziyo ikiristaro zvishoma.
Iyo STM32L412xx inoshanda mu -40 kusvika +85 °C (+105 °C junction) uye -40 kusvika +125 °C (+130 °C junction) tembiricha inotangira pa1.71 kusvika 3.6 VDD magetsi kana uchishandisa yemukati LDO regulator. uye 1.00 kusvika 1.32V VDD12 magetsi ekushandisa paunenge uchishandisa kunze kweSMPS kupa.Iyo yakazara seti yemamodhi ekuchengetedza simba inoita kuti zvigoneke dhizaini yeakaderera-simba maapplication.
Mamwe magetsi akazvimiririra anotsigirwa: analogi yakazvimiririra yekupa pepu yeADC, OPAMP uye comparator.Kupinza kweVBAT kunoita kuti zvikwanise kuchengetedza RTC uye marejista ekuchengetedza.Yakatsaurirwa VDD12 magetsi emagetsi anogona kushandiswa kupfuura iyo yemukati LDO regulator kana yakabatana kune yekunze SMPS.
Iyo STM32L412xx mhuri inopa mapakeji matanhatu kubva pa32 kusvika 64-pini mapakeji.
