Hoʻokumu ʻia nā polokalamu STM32F412XE/G i ka Arm® Cortex® -M4 32-bit kiʻekiʻe.Hana ʻia ka RISC core ma ke alapine a hiki i 100 MHz.ʻO kā lākou Cortex®-M4 mau hiʻohiʻona aFloating point unit (FPU) hoʻokahi pololei e kākoʻo ana i nā ʻōlelo aʻo a me nā ʻano ʻikepili āpau.Hoʻokomo pū ia i kahi hoʻonohonoho piha o nā kuhikuhi DSP akahi ʻāpana pale hoʻomanaʻo (MPU) e hoʻonui ai i ka palekana noi.
Aia nā polokalamu STM32F412XE/G i ka laina huahana STM32 Dynamic Efficiency™ (menā huahana e hui pū ana i ka pono o ka mana, ka hana a me ka hoʻohui) me ka hoʻohui ʻana i kahi mea houʻO kahi hiʻohiʻona hou i kapa ʻia ʻo Batch Acquisition Mode (BAM) e ʻae ai i ka mana hou akuka mālama ʻana i ka hoʻohana ʻana i ka wā o ka hōʻiliʻili ʻikepili.
Hoʻokomo nā mea STM32F412XE/G i nā hoʻomanaʻo i hoʻopili ʻia (a hiki i 1 Mbyte oMemo uila, 256 Kbytes o SRAM), a me ka laulā o nā I/O i hoʻonui ʻia anā peripherals i pili i ʻelua pahi APB, ʻekolu pahi AHB a me kahi pahi multi-AHB 32-bit.matrix.
Hāʻawi nā mea hana āpau i hoʻokahi 12-bit ADC, kahi RTC haʻahaʻa haʻahaʻa, ʻumikūmālua mau manawa 16-bit kumu nui,ʻelua mau manawa PWM no ka hoʻokele kaʻa a me ʻelua mau manawa 32-bit kumu nui.
Hāʻawi pū lākou i nā pilina kamaʻilio maʻamau a holomua:
• A hiki i ʻehā I2C, me hoʻokahi I2C e kākoʻo ana i ka Fast-Mode Plus
• Elima SPI
• Elima I2S o ia mau mea elua he duplex piha.No ka hoʻokō ʻana i ka pololei o ka papa leo, ʻo ka I2SHiki ke hoʻopaʻa ʻia nā peripherals ma o ka PLL leo kūloko i hoʻolaʻa ʻia, a i ʻole ma o ka uaki wahoe ʻae i ka synchronization.
• ʻEhā USART
• He polokalamu SDIO/MMC
• He USB 2.0 OTG piha-wikiwiki
• Elua CAN.
Eia kekahi, hoʻokomo nā mea STM32F412xE/G i nā peripheral holomua:
• He kikowaena hoʻoponopono hoʻomanaʻo hoʻomanaʻo maʻalahi (FSMC)
• He pānaʻi hoʻomanaʻo Quad-SPI
• He kānana kikohoʻe no ka modulator sigma (DFSDM), ʻelua kānana, a hiki i ʻehā hoʻokomo, a me ke kākoʻoo na microphone MEM.
Hāʻawi ʻia nā mea STM32F412xE/G i 7 mau pūʻolo mai 48 a 144 mau pine.ʻO ka hoʻonohonoho opili nā peripheral i loaʻa ma ka pūʻolo i koho ʻia.
Hoʻohana ka STM32F412xE/G i ka -40 a +125 °C wela wela mai kahi 1.7 (PDR).OFF) i ka lako mana 3.6 V.ʻO kahi hoʻonohonoho piha o nā ʻano hoʻopakele mana e ʻae i ka hoʻolālāo na noi haahaa.
