Midziyo yeSTM32L451xx 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 STM32L451xx midziyo yakamisikidza yakakwira-kumhanya ndangariro (Flash memory inosvika 512 Kbyte, 160 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 STM32L451xx zvishandiso zvakanyudza akati wandei nzira dzekudzivirira dzakamisikidzwa Flash memory uye SRAM: chengetedzo yekuverenga, kuchengetedzwa kwekunyora, kodhi kodhi kuverenga kuchengetedzwa uye Firewall.
Midziyo iyi inopa inokurumidza 12-bit ADC (5 Msps), maviri anoenzanisa, imwe inoshanda amplifier, imwe 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.
Ivo zvakare vanoratidza mwero uye yepamusoro kukurukurirana interfaces, kureva mana I2Cs, matatu SPIs, matatu UARTs, imwe UART uye imwe Low-Simba UART, imwe SAI, imwe SDMMC, mumwe CAN.
Iyo STM32L451xx inoshanda mu -40 kusvika +85 °C (+105 °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 inoita kuti zvigoneke dhizaini yeakaderera-simba maapplication.
Mamwe magetsi akazvimiririra anotsigirwa: analogi yakazvimiririra yekuisa yekuisa yeADC, DAC, OPAMP uye vaenzanisi.Kupinza kweVBAT kunoita kuti zvikwanise kuchengetedza RTC uye marejista ekuchengetedza.
Iyo STM32L451xx mhuri inopa mapakeji matanhatu kubva pa48 kusvika zana-pini mapakeji.
