♠ Ultra-iti-mana Arm® Cortex®-M4 32-bit MCU+FPU, 100DMIPS, tae atu ki te 128KB Flash, 40KB SRAM, analog, ext. SMPS
Ko nga taputapu STM32L412xx he 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 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 e hono ana ki nga pahi APB e rua, e rua nga pahi AHB me te 32-bit matrix multi-AHB.
Ko nga taputapu STM32L412xx 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.
Ko nga taputapu e tuku ana kia rua nga ADC 12-bit tere (5 Msps), e rua nga whakatairite, kotahi te whakakaha whakahaere, he RTC iti-hiko, kotahi moka-32-matama-a-whanui, kotahi moka-16 PWM matawā i whakatapua ki te whakahaere motuka, e wha moka-whānui-a-16-matama, me te rua moka-16 matawā iti-hiko.
I tua atu, tae atu ki te 12 nga hongere capacitive sensing e waatea ana.
Kei roto hoki i a raatau nga atanga korero paerewa me te matatau, ara e toru nga I2C, e rua nga SPI, e toru nga USART me tetahi UART Mana-iti, kotahi te karaihe taputapu tere-katoa USB he iti ake.
Ko te STM32L412xx 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) te pāmahana mai i te 1.71 ki te 3.6 V VDD mana hiko i te whakamahi i te kaiwhakahaere LDO o roto me te 1.00 ki te 1.00 ki te 1.32V o waho. 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: urunga tukunga motuhake tairitenga mo ADC, OPAMP me te kaiwhakariterite. Ma te whakaurunga VBAT ka taea te whakahoki i te RTC me nga rehita taapiri. Ka taea te whakamahi i nga taputapu hiko VDD12 ki te karo i te kaiwhakahaere LDO o roto ina hono ana ki tetahi SMPS o waho.
Ko te whanau STM32L412xx e tuku ono nga kete mai i te 32 ki te 64-pin nga kete.
