STM32G474CET6 IC MCU 32BIT 512KB IFLESHI 48LQFP

Inkcazo

Izixhobo ze-STM32G474xB/xC/xE zisekelwe kwi-Arm® Cortex®-M4 32-bit ye-RISC ephezulu yokusebenza.Basebenza rhoqo ukuya kuthi ga kwi-170 MHz.Undoqo weCortex-M4 ubonisa iyunithi enye echanekileyo edadayo (i-FPU), exhasa yonke imiyalelo ye-Arm echanekileyo yokucubungula idatha kunye nazo zonke iintlobo zedatha.Ikwasebenzisa isethi epheleleyo ye-DSP (idijithali yokulungiswa komqondiso) imiyalelo kunye neyunithi yokukhusela imemori (MPU) eyandisa ukhuseleko lwesicelo.Ezi zixhobo zifakela iinkumbulo zesantya esiphezulu (ukuya kwi-512 Kbytes yememori ye-Flash, kunye ne-128 Kbytes ye-SRAM), isilawuli sememori yangaphandle eguquguqukayo (FSMC) yeenkumbulo ezimileyo (kwizixhobo ezineephakheji ze-100 nezikhonkwane nangaphezulu), i-Quad-SPI. I-Flash memory interface, kunye noluhlu olubanzi lwee-I/Os eziphuculweyo kunye neeperipherals eziqhagamshelwe kwiibhasi ezimbini ze-APB, iibhasi ezimbini ze-AHB kunye ne-32-bit ye-multi-AHB yebhasi matrix.Izixhobo zikwafaka iindlela ezininzi zokukhusela kwimemori yeFlash kunye ne-SRAM: ukukhuselwa kokufunda, ukhuseleko lokubhala, indawo yememori ekhuselekileyo kunye nokukhusela ikhowudi yokufunda.Izixhobo zifakela iiperipherals ezivumela ukukhawuleza komsebenzi wezibalo/arithmetic (i-CORDIC yemisebenzi yetrigonometric kunye neyunithi ye-FMAC yemisebenzi yokucoca).Banikezela ngee-ADC ezi-12 ezikhawulezayo (i-4 Msps), abathelekisi abasixhenxe, ii-amplifiers ezintandathu zokusebenza, iziteshi ezisixhenxe ze-DAC (i-3 yangaphandle kunye ne-4 yangaphakathi), i-buffer yereferensi yombane yangaphakathi, i-RTC yamandla aphantsi, i-32-bit timers ezimbini zenjongo jikelele, Izibali-xesha ezintathu ze-16-bit ze-PWM ezinikezelwe kulawulo lweemoto, izibali-xesha ezisixhenxe zenjongo jikelele ye-16-bit, kunye ne-16-bit enye ye-low-power timer, kunye ne-high resolution timer ene-184 ps resolution.
