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 o 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 kei te 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 pateko (mo nga taputapu whai kete 100 titi me te maha atu), he atanga maharatanga Quad SPI (e waatea ana i nga kohinga katoa) me te hono atu i nga paanui periphera e rua ki te A/P. e rua nga pahi AHB me te 32-bit multi-AHB matrix pahi.
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 Patuahi.
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 parepare tohutoro ngaohiko a-roto, he RTC iti-hiko, e rua moka-32-matama-a-whaanui, e rua moka-16-waea PWM i whakatapua ki te whakahaere motuka, e whitu nga mahi-a-whanui 16-bit matawā 16-bit iti, me te rua moka-mahi 16-bit timers iti. Ko nga taputapu e tautoko ana i nga whiriwhiringa mamati e wha mo nga tauira o waho o te sigma delta modulators (DFSDM).
