Hoʻokumu ʻia nā mea STM32F745xx a me STM32F746xx ma luna o ka hana kiʻekiʻe ARM® Cortex®-M7 32-bit RISC core e hana ana a hiki i ka 216 MHz frequency.Hōʻike ʻia ka Cortex®-M7 core i kahi kiko lana hoʻokahi (SFPU) pololei e kākoʻo ana i nā ʻōlelo aʻo a me nā ʻano ʻikepili a pau ARM® singleprecision.Hoʻokomo pū ia i kahi pūʻulu piha o nā ʻōlelo aʻoaʻo DSP a me kahi ʻāpana pale hoʻomanaʻo (MPU) e hoʻonui ai i ka palekana noi.Hoʻokomo nā mea STM32F745xx a me STM32F746xx i nā mea hoʻomanaʻo i hoʻokomo ʻia me ka hoʻomanaʻo Flash a hiki i 1 Mbyte, 320 Kbytes o SRAM (me 64 Kbytes o Data TCM RAM no ka ʻikepili koʻikoʻi manawa maoli), 16 Kbytes o ke aʻo ʻana TCM RAM (no ke koʻikoʻi maoli. -ʻo ka manawa maʻamau), 4 Kbytes o ka SRAM hoʻihoʻi i loaʻa i nā ʻano mana haʻahaʻa loa, a me kahi ākea o nā I/Os i hoʻonui ʻia a me nā peripheral i pili i ʻelua mau pahi APB, ʻelua mau pahi AHB, kahi 32-bit multi-AHB matrix a me kahi multi layer AXI interconnect e kākoʻo ana i ka hoʻomanaʻo i loko a me waho.Hāʻawi nā mea hana āpau i ʻekolu 12-bit ADCs, ʻelua DAC, kahi RTC haʻahaʻa haʻahaʻa, ʻumikūmākolu mau manawa 16-bit kumu nui me ʻelua mau manawa PWM no ka hoʻokele kaʻa a hoʻokahi manawa mana haʻahaʻa i loaʻa i ka mode Stop, ʻelua kumu nui 32-bit. nā manawa, kahi mea hoʻoheheʻe helu random maoli (RNG).Hāʻawi pū lākou i nā pilina kamaʻilio maʻamau a holomua.
