Ko nga taputapu STM32L476xx ko nga microcontrollers ultra-iti-hiko i runga i te mahinga teitei Arm® Cortex®-M4 32-bit RISC matua e mahi ana i te auau ki te 80 MHz.Ko te matua o Cortex-M4 e whakaatu ana i te waeine ira maangi (FPU) kotahi e tautoko ana i nga tohutohu tukatuka raraunga me nga momo raraunga katoa a Arm®.Ka whakatinanahia hoki he huinga katoa o nga tohutohu DSP me tetahi wae tiaki mahara (MPU) e whakanui ana i te haumarutanga tono.
Ko nga taputapu STM32L476xx ka whakauru i nga maharatanga tere-tere (te mahara Flash ki te 1 Mbyte, tae atu ki te 128 Kbyte o SRAM), he kaiwhakahaere mahara-waho ngawari (FSMC) mo nga maharatanga tuuturu (mo nga taputapu he 100 nga pine me etahi atu), he Quad SPI atanga mahara flash (e waatea ana i runga i nga kete katoa) me te whānuitanga o nga I/Os whakarei me nga peripheral e hono ana ki nga pahi APB e rua, nga pahi AHB e rua me te matrix pahi maha-AHB 32-bit.
Ko nga taputapu STM32L476xx he maha nga tikanga whakamarumaru mo te mahara Flash me te SRAM kua whakauruhia: te whakamarutanga panui, te whakamarutanga tuhi, te whakamarumaru panui waehere me te Paahiahi.
Ko nga taputapu e tuku ana kia toru nga ADC 12-bit tere (5 Msps), e rua nga kaiwhakariterite, e rua nga whakakaha whakahaere, e rua nga waahana DAC, he papaa tohu tohutoro ngaohiko o roto, he RTC iti-hiko, e rua nga waahanga moka-32, e rua 16 -bit PWM timers i whakatapua ki te whakahaere motopaika, e whitu moka-whānui matawā 16-bit, me e rua 16-bit-iti-hiko matawā.Ko nga taputapu e tautoko ana i nga whiriwhiringa mamati e wha mo nga tauira o waho o te sigma delta modulators (DFSDM).
