STM32F405VGT7 ARM Microcontrollers MCU Hi-hana DSP FPU ARM CortexM4 MCU

Hoʻokumu ʻia ka ʻohana STM32F405xx a me STM32F407xx i ka Arm® kiʻekiʻe.Cortex®-M4 32-bit RISC core e hana ana ma ke alapine a hiki i ka 168 MHz.ʻO ka Cortex-M4ʻO nā hiʻohiʻona koʻikoʻi kahi Floating point unit (FPU) hoʻokahi kikoʻī e kākoʻo ana i nā ʻōlelo aʻoaʻo a me nā ʻano ʻikepili Arm singleprecision.Hoʻokomo pū ia i kahi pūʻulu piha o DSPnā ʻōlelo aʻo a me kahi ʻāpana pale hoʻomanaʻo (MPU) e hoʻonui ai i ka palekana o ka noi.

Hoʻokomo ʻia ka ʻohana STM32F405xx a me STM32F407xx i hoʻokomo ʻia ka wikiwiki kiʻekiʻe.hoʻomanaʻo (Flash memory a hiki i 1 Mbyte, a hiki i 192 Kbytes o SRAM), a hiki i 4 Kbytes obackup SRAM, a me ka laulā nui o nā I/Os i hoʻonui ʻia a me nā peripheral i pili i ʻeluaNā kaʻa kaʻa APB, ʻekolu mau kaʻa kaʻa AHB a me kahi matrix bus 32-bit multi-AHB.

Hāʻawi nā mea hana āpau i ʻekolu 12-bit ADC, ʻelua DAC, kahi RTC haʻahaʻa haʻahaʻa, ʻumikūmālua kumu nui.16-bit timers me ʻelua PWM timers no ka hoʻokele kaʻa, ʻelua kumu nui 32-bit timers.he mea hoʻoheheʻe helu random maoli (RNG).Hāʻawi pū lākou i ka maʻamau a me ka holomuanā pilina pili.

• A hiki i ekolu I2C

• ʻEkolu SPI, ʻelua I2Ss duplex piha.No ka hoʻokō ʻana i ka pololei o ka papa leo, nā peripheral I2Shiki ke hoʻopaʻa ʻia ma o ka PLL leo kūloko i hoʻolaʻa ʻia a i ʻole ma o ka uaki waho e ʻaehoʻolikelike.

• ʻEhā USART me ʻelua mau UART

• He USB OTG piha-wikiwiki a me ka USB OTG kiʻekiʻe-wikiwiki me ka piha-wikiwiki hiki (me kaULPI),

• Elua CAN

• He polokalamu SDIO/MMC

• Loaʻa ka Ethernet a me ke kāʻei pahu pahu ma nā mea STM32F407xx wale nō.

Loaʻa i nā peripherals hou kahi SDIO, kahi mana hoʻomanaʻo static i hoʻonui ʻia(FSMC) interface (no nā mea hana i hāʻawi ʻia i loko o nā pūʻolo o 100 pine a ʻoi aku), kahi pahupaʻihoʻopili no nā mea ʻike CMOS.E nānā i ka Papa 2: STM32F405xx a me STM32F407xx: nā hiʻohiʻonaa me nā helu āpau no ka papa inoa o nā peripheral i loaʻa ma kēlā me kēia helu ʻāpana.

Ke hana nei ka ʻohana STM32F405xx a me STM32F407xx ma ke ana wela –40 a +105 °C.mai ka 1.8 a i ka 3.6 V mana lako.Hiki ke hāʻule ka volta hāʻawi i ka 1.7 V i ka wā o kaKe hana nei ka mea hana ma ka 0 a 70 °C me ka hoʻohana ʻana i kahi lako mana waholuna: e nānā i ka ʻāpana: Hoʻoponopono i loko OFF.ʻO kahi pūʻulu piha o ka mālama manaʻAe ke ʻano i ka hoʻolālā ʻana i nā noi haʻahaʻa.

Hāʻawi ka ʻohana STM32F405xx a me STM32F407xx i nā polokalamu ma nā ʻāpana like ʻole.mai 64 pine a 176 pine.Hoʻololi ka pūʻulu o nā peripheral me ka mea i koho ʻia.Ua kūpono kēia mau hiʻohiʻona i ka ʻohana microcontroller STM32F405xx a me STM32F407xx.no ka laulā o nā noi:

• kaʻa kaʻa a me ka mana noi

• Lapaau lapaau

• Nā noi hana: PLC, inverters, circuit breakers

• Nā mea paʻi, a me nā mīkini paʻi

• Pūnaehana alarm, intercom wikiō, a me HVAC

• Nā lako leo home
