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 he 100 nga pine me etahi atu), he Quad SPI Flash atanga maumahara (e waatea ana i runga i nga kohinga katoa) me te whānuitanga o nga I/O kua whakareia me nga peripheral e hono ana ki nga pahi APB e rua, nga pahi AHB e rua me te matrix pahi maha-AHB 32-bit.
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 papaa tohu tohutoro ngaohiko o roto, he RTC iti-hiko, e rua nga waahanga moka-32, e rua 16 -bit PWM timers i whakatapua ki te whakahaere motopaika, e whitu moka-whānui matawā 16-bit, me e rua 16-bit-iti-hiko matawā.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 (kawa waea kotahi. atanga matua), he atanga kamera me te kaiwhakahaere DMA2D.
Ko te STM32L496xx e mahi ana i roto i te -40 ki te +85 °C (+105 °C te hononga), -40 ki te +125 °C (+130 °C te hononga) 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 tuku hiko 1.05 ki te 1.32V VDD12 i te wa e whakamahi ana i te tuku SMPS o waho.Ma te huinga matawhānui o nga momo penapena hiko ka taea te hoahoa o nga tono hiko iti.
E tautokohia ana etahi taputapu hiko motuhake: te whakaurunga tukunga motuhake tairitenga mo ADC, DAC, OPAMPs 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 pūrua te RTC me ngā rehita tārua.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.
