Whakaahuatanga
Ko nga taputapu STM32L443xx 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 STM32L443xx ka whakauru i nga maharatanga tere-tere (256 Kbyte o te mahara Flash, 64 Kbyte o te SRAM), he atanga maharatanga kohiko Quad SPI (e waatea ana i runga i nga kohinga katoa) me te whānuitanga o nga I/Os whakarei me nga peripheral e hono ana ki nga pahi APB e rua, e rua nga pahi AHB me te 32-bit multi-AHB matrix pahi.Ko nga taputapu STM32L443xx 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.Ka tukuna e nga taputapu he ADC 12-bit tere (5 Msps), e rua nga kaiwhakariterite, kotahi te whakahiato mahi, e rua nga hongere DAC, he kaitao tohutoro ngaohiko a-roto, he RTC iti-hiko, kotahi te matama moka-32, kotahi matama PWM 16-bit. i whakatapua ki te whakahaere motika, e wha nga tohu moka-16 moka-whaanui, me te rua moka-16-iti-hiko matawā.I tua atu, tae atu ki te 21 nga hongere capacitive sensing e waatea ana.Ka whakauruhia ano e nga taputapu he taraiwa LCD whakauru 8x40 ranei 4x44, me te kaitahuri hikoi-a-roto.
