Whakaahuatanga
Ko nga taputapu STM32L412xx he microcontrollers-iti-iti i runga i te tino mahi 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 STM32L412xx kei te whakauru i nga maharatanga tere-tere (te mahara Flash ki te 128 Kbyte, 40 Kbyte o SRAM), he atanga maharatanga Quad SPI Flash (e waatea ana i runga i nga kohinga katoa) me te whānuitanga o nga I/Os whakarei me nga peripheral hono ki nga pahi APB e rua. , e rua nga pahi AHB me te 32-bit multi-AHB matrix pahi.Ko nga taputapu STM32L412xx he maha nga tikanga whakamarumaru mo te mahara Flash me te SRAM kua whakauruhia: te whakamaru i te panui, te whakamarutanga tuhi, te whakamarumaru panui waehere me te Patuahi.Ko nga taputapu e tuku ana kia rua nga ADC 12-bit tere (5 Msps), e rua nga kaiwhakariterite, kotahi te whakakaha whakahaere, he RTC iti-hiko, kotahi te matama moka-32-a-whanui, kotahi moka-16 matama PWM i whakatapua ki te whakahaere motuka, e wha whaa- moka-16 moka-wa-waa, me nga moka-16-iti e rua.
