Whakaahuatanga
Ko te whanau STM32F405xx me STM32F407xx kei runga i te tino mahi Arm® Cortex®-M4 32-bit RISC matua e mahi ana i te auau ki te 168 MHz.Ko te matua Cortex-M4 e whakaatu ana i te waeine ira maangi (FPU) kotahi e tautoko ana i nga tohutohu tukatuka raraunga me nga momo raraunga Arm singleprecision.Ka whakatinanahia hoki he huinga katoa o nga tohutohu DSP me tetahi wae tiaki mahara (MPU) e whakanui ana i te haumarutanga tono.Ko te whanau STM32F405xx me STM32F407xx ka whakauru i nga mahara whakauru tere-tere (Mahara Flash ki te 1 Mbyte, tae atu ki te 192 Kbytes o SRAM), tae atu ki te 4 Kbytes o te SRAM taapiri, me te whānuitanga o nga I/Os whakarei me nga peripheral hono ki te rua APB pahi, toru pahi AHB me te 32-bit multi-AHB matrix pahi.Ka tukuna e nga taputapu katoa nga ADC 12-bit e toru, e rua nga DAC, he RTC iti-hiko, tekau ma rua nga waahi moka-16-a-whanui tae atu ki nga matawā PWM e rua mo te whakahaere motopaika, e rua nga waahi moka-32-whanui.he kaihanga tau matapōkere pono (RNG).Kei a raatau ano nga atanga korero paerewa me te matatau.
