Kev piav qhia
Cov khoom siv STM32L475xx yog ultra-low-power microcontrollers raws li qhov ua tau zoo Arm® Cortex®-M4 32-ntsis RISC core ua haujlwm ntawm ntau zaus txog 80 MHz.Lub Cortex-M4 core nta Floating point unit (FPU) ib qho kev txiav txim siab uas txhawb nqa tag nrho Arm® ib leeg-cov ntaub ntawv ua tiav cov lus qhia thiab hom ntaub ntawv.Nws kuj tseem siv tag nrho DSP cov lus qhia thiab lub cim xeeb tiv thaiv (MPU) uas txhim kho daim ntawv thov kev ruaj ntseg.Cov khoom siv STM32L475xx embed high-speed nco (Flash nco txog li 1 Mbyte, mus txog 128 Kbyte ntawm SRAM), ib tug saj zawg zog sab nraud nco controller (FSMC) rau zoo li qub nco (rau cov khoom siv nrog 100 pins pob), Quad SPI flash nco interface (muaj nyob rau hauv tag nrho cov pob khoom) thiab ntau yam ntawm 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 STM32L475xx embed ob peb kev tiv thaiv mechanisms rau embedded Flash nco thiab SRAM: nyeem ntawv tiv thaiv, sau ntawv tiv thaiv, proprietary code nyeem ntawv tiv thaiv thiab Firewall.Cov cuab yeej muaj txog peb qhov ceev 12-ntsis ADCs (5 Msps), ob qhov sib piv, ob lub tshuab ua haujlwm, ob lub DAC raws, ib qho kev siv hluav taws xob sab hauv, lub zog qis RTC, ob lub hom phiaj 32-ntsis timer, ob 16 -bit PWM timers mob siab rau kev tswj lub cev muaj zog, xya lub hom phiaj 16-ntsis timers, thiab ob lub sijhawm 16-ntsis qis zog.Cov cuab yeej txhawb nqa plaub lub lim dej rau sab nraud sigma delta modulators (DFSDM).
