♠ Ultra-iti-mana Arm® Cortex®-M4 32-bit MCU+FPU, 100 DMIPS, tae atu ki te 1 MB Flash, 320 KB SRAM, USB OTG FS, ororongo, SMPS waho
Ko nga taputapu STM32L496xx 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 STM32L496xx ka whakauru i nga maharatanga tere-tere (tae atu ki te 1 Mbyte o te mahara Flash, 320 Kbyte o SRAM), he kaiwhakahaere mahara-waho ngawari (FSMC) mo nga maharatanga pateko (mo nga taputapu me nga kete 100 pine me etahi atu), he atanga maharatanga Quad SPI Flash (e waatea ana ki nga kohinga katoa) me te awhe I/O kua honoa ki te rua o nga awhe APB Nga pahi AHB me te 32-bit maha-AHB matrix pahi.
Ko nga taputapu STM32L496xx 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 Paahiahi.
Ko nga taputapu e tuku ana kia toru nga ADC 12-bit tere (5 Msps), e rua nga kaiwhakariterite, e rua nga whakakaha whakahaere, e rua nga waahana DAC, he parepare tohutoro ngaohiko a-roto, he RTC iti-hiko, e rua moka-32-matama-a-whaanui, e rua moka-16-waea PWM i whakatapua ki te whakahaere motuka, e whitu nga mahi-a-whanui 16-bit matawā 16-bit iti, me te rua moka-mahi 16-bit timers iti. Ko nga taputapu e tautoko ana i nga whiriwhiringa mamati e wha mo nga tauira o waho o te sigma delta modulators (DFSDM).
I tua atu, tae atu ki te 24 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.
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, e rua nga UART me tetahi UART Mana-iti, e rua SAI, kotahi SDMMC, e rua CAN, kotahi USB OTG tere-katoa, kotahi SWPMI (kotahi atanga matua kawa waea), he atanga kamera me te kaiwhakahaere DMA2D.
Ko te STM32L496xx e mahi ana i roto i te -40 ki te +85 °C (+105 °C junction), -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 wa e whakamahi ana i te kaiwhakahaere LDO o roto me te 1.05 ki te 1.32V VDD 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: te whakaurunga whakaurunga motuhake mo te ADC, DAC, OPAMP me nga kaiwhakariterite, 3.3 V whakatapua urunga tuku mo te USB me te 14 I/Os ka taea te tuku takitahi ki te 1.08 V. Ma te whakauru 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 STM32L496xx e tuku ana i nga kete e whitu mai i te 64-pin ki nga kete 169-pin.
