♠ Arm® Cortex®-M7 32-bit 550 MHz MCU, kufika ku-1 MB Flash, 564 KB RAM, Ethernet, USB, 3x FD-CAN, Graphics, 2x 16-bit ADCs
Amadivayisi we-STM32H723xE/G asekelwe kumongo osebenza kakhulu we-Arm® Cortex®-M7 32-bit RISC osebenza kokufika ku-550 MHz. I-Cortex® -M7 core ineyunithi yephoyinti elintantayo (i-FPU) esekela ukunemba okuphindwe kabili kwe-Arm® (i-IEEE 754 ethobelayo) kanye nemiyalo yokucubungula idatha enembayo kanye nezinhlobo zedatha. I-Cortex -M7 core ihlanganisa ama-Kbytes angu-32 wenqolobane yemfundo kanye nama-Kbytes angu-32 wenqolobane yedatha. Imishini ye-STM32H723xE/G isekela isethi egcwele yemiyalelo ye-DSP kanye neyunithi yokuvikela inkumbulo (MPU) ukuze kuthuthukiswe ukuphepha kohlelo lokusebenza.
Amadivayisi we-STM32H723xE/G ahlanganisa izinkumbulo ezishumekwe ngesivinini esiphezulu ezinokufika ku-1 Mbyte yememori ye-Flash, efika ku-564 Kbytes we-RAM (okuhlanganisa no-192 Kbytes okungabelwanwa ngawo phakathi kwe-ITCM ne-AXI, kanye nama-Kbytes angu-64 ngokukhethekileyo i-ITCM, kanye no-128 KTCClyte DTCB8, Excclusive 2M8 48 Kbytes AHB kanye no-4 Kbytes we-RAM eyisipele), kanye nohlu olubanzi lwama-I/Os nama-peripheral athuthukisiwe axhunywe kumabhasi e-APB, amabhasi e-AHB, i-matrix yebhasi engu-2x32-bit multi-AHB kanye ne-multi layer AXI exhumanisayo esekela ukufinyelela kwememori yangaphakathi nangaphandle. Ukuthuthukisa ukuqina kohlelo lokusebenza, zonke izinkumbulo zifaka phakathi ukulungiswa kwekhodi yephutha (ukulungisa iphutha elilodwa, ukutholwa kwamaphutha amabili).
Ingqikithi
