STM32L452CEU6 IC MCU 32BIT 512KB FLASH 48UFQFPN

Tsanangudzo

Midziyo yeSTM32L452xx 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 STM32L452xx 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 STM32L452xx zvishandiso zvakanyudza akati wandei nzira dzekudzivirira dzakamisikidzwa Flash memory uye SRAM: chengetedzo yekuverenga, kuchengetedzwa kwekunyora, kodhi kodhi kuverenga kuchengetedzwa uye Firewall.Midziyo iyi inopa kukurumidza 12-bit ADC (5 Msps), maviri anoenzanisa, imwe inoshanda amplifier, imwe 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.Vanoitawo mureza uye yepamusoro kukurukurirana interfaces, kureva mana I2Cs, matatu SPIs, matatu UARTs, mumwe UART uye mumwe Low-Simba UART, mumwe SAI, mumwe SDMMC, mumwe CAN, mumwe USB akazara-nokukurumidza mudziyo crystal zvishoma.Iyo STM32L452xx 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 1.05 kusvika 1.32V VDD12 magetsi ekushandisa paunenge uchishandisa kunze kweSMPS kupa.Iyo yakazara seti yemamodhi ekuchengetedza magetsi inoita kuti zvikwanisike dhizaini yemashandisirwo emagetsi mashoma.Mamwe magetsi akazvimiririra anotsigirwa: analogi yakazvimiririra yekuisa yekuisa yeADC, DAC, OPAMP uye vaenzanisi.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 STM32L452xx mhuri inopa manomwe mapakeji kubva pamakumi mana nesere kusvika zana-pini mapakeji.
