STM32L552ZET6 IC MCU 32BIT 512KB FLASH 144LQFP

Kev piav qhia

Cov khoom siv STM32L552xx yog tsev neeg ultra-low-power microcontrollers (STM32L5 Series) raws li qhov ua tau zoo Arm® Cortex®-M33 32-ntsis RISC core.Lawv ua haujlwm ntawm qhov zaus mus txog 110 MHz.Lub Cortex®-M33 core nta ib qhov kev txiav txim siab floating-point unit (FPU), uas txhawb nqa tag nrho Arm® ib leeg-txhim kho cov ntaub ntawv-ua cov lus qhia thiab txhua hom ntaub ntawv.Cortex®-M33 core kuj tseem siv tag nrho DSP (digital signal processing) cov lus qhia thiab lub cim xeeb tiv thaiv (MPU) uas txhim kho daim ntawv thov kev ruaj ntseg.Cov khoom siv no suav nrog kev nco ceev ceev (512 Kbytes ntawm Flash nco thiab 256 Kbytes ntawm SRAM), hloov pauv lub cim xeeb sab nraud (FSMC) rau kev nco zoo li qub (rau cov khoom siv nrog pob ntawm 100 pins thiab ntau dua), Octo-SPI Flash nco interface (muaj nyob rau hauv tag nrho cov pob khoom) thiab ntau yam kev txhim kho I/Os thiab peripherals txuas nrog ob lub tsheb npav APB, ob lub tsheb npav AHB thiab 32-ntsis multi-AHB tsheb npav matrix.Cov khoom siv STM32L5 Series muaj kev ruaj ntseg hauv paus raws li kev ntseeg siab raws li kev ruaj ntseg architecture (TBSA) yuav tsum tau los ntawm Arm.Lawv embed qhov tsim nyog kev ruaj ntseg nta los siv ib tug ruaj ntseg khau raj, ruaj ntseg cov ntaub ntawv cia, ruaj ntseg firmware installation thiab ruaj ntseg firmware upgrade.Lub neej voj voog hloov pauv tau tswj hwm ua tsaug rau ntau qib ntawm kev tiv thaiv nyeem ntawv.Firmware hardware cais tawm tau txais kev txhawb nqa ua tsaug rau kev ruaj ntseg peripherals, nco thiab I/Os, thiab tseem muaj peev xwm teeb tsa cov khoom siv peripherals thiab nco ua "tsim cai".Cov khoom siv STM32L552xx embed ob peb kev tiv thaiv mechanisms rau embedded Flash nco thiab SRAM: nyeem ntawv tiv thaiv, sau ntawv tiv thaiv, ruaj ntseg thiab zais chaw tiv thaiv.
