Iyo STM32L476xx midziyo ndiyo yekupedzisira-yakaderera-simba microcontrollers yakavakirwa pamusoro-inoshanda 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 STM32L476xx midziyo yakamisikidza yakakwira-kumhanya ndangariro (Flash memory inosvika 1 Mbyte, inosvika 128 Kbyte yeSRAM), inochinjika yekunze memory controller (FSMC) yekurangarira static (yemidziyo ine mapakeji e100 mapini uye nezvimwe), Quad SPI flash memory interface (inowanikwa pane akawandisa mapeji epakeji uye akabatana emapakeji eO. mabhazi maviri eAPB, mabhazi maviri eAHB uye 32-bit akawanda-AHB bhazi matrix.
Iyo STM32L476xx michina yakanyudza nzira dzinoverengeka dzekudzivirira dzakamisikidzwa Flash memory uye SRAM: chengetedzo yekuverenga, kuchengetedzwa kwekunyora, kodhi kodhi kuverenga kuchengetedzwa uye Firewall.
Midziyo iyi inopa kusvika matatu anokurumidza 12-bit ADCs (5 Msps), maviri anoenzanisa, maviri ekushandisa amplifiers, maviri eDAC chiteshi, yemukati voltage referensi buffer, yakaderera-simba RTC, maviri general-chinangwa 32-bit timer, maviri 16-bit PWM timers akatsaurirwa kudzora mota, manomwe general-chinangwa 16-bit 16-bit timer, uye yakaderera-bit 16-bit timer. Iwo maturusi anotsigira mana edhijitari mafirita ekunze sigma delta modulators (DFSDM).
