Ko nga taputapu STM32L451xx he microcontrollers ultra-iti-hiko 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 STM32L451xx ka whakauru i nga maharatanga tere-tere (te mahara Flash ki te 512 Kbyte, 160 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 STM32L451xx 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, kotahi te hongere DAC, he parepare tohutoro ngaohiko a-roto, he RTC iti-hiko, kotahi moka-32-a-whara, kotahi moka-16. Matawā PWM i whakatapua ki te mana motopaika, e wha nga matawā moka-16 moka-whānui, me nga moka-16-iti-hiko e rua.
I tua atu, tae atu ki te 21 nga hongere capacitive sensing e waatea ana.
Kei roto hoki i a raatau nga atanga korero paerewa me te matatau, ara e wha nga I2C, e toru nga SPI, e toru nga USART, kotahi UART me tetahi UART Mana-iti, kotahi SAI, kotahi SDMMC, kotahi CAN.
Ko te STM32L451xx e mahi ana i roto i te -40 ki te +85 °C (+105 °C junction) me te -40 ki te +125 °C (+130 °C junction) mai i te 1.71 ki te 3.6 V te mana hiko.Ma te huinga matawhānui o nga momo penapena hiko ka taea te hoahoa o nga tono hiko iti.
Kei te tautokohia etahi taputapu hiko motuhake: whakaurunga toha motuhake mo ADC, DAC, OPAMP me nga kaiwhakarite.Ma te whakaurunga VBAT ka taea te whakahoki i te RTC me nga rehita taapiri.
Ko te whanau STM32L451xx e tuku ono nga kete mai i te 48 ki te 100-pin nga kete.
