♠ Laina komo i ka mana loa 32-bit MCU Arm®-based Cortex®-M0+, a hiki i 64 KB Flash, 8 KB SRAM, 2 KB EEPROM, ADC
Hoʻokomo ʻia ka laina komo ultra-low-power STM32L051x6/8 microcontrollers kiʻekiʻe Arm Cortex-M0+ 32-bit RISC core e hana ana ma kahi alapine 32 MHz, kahi hoʻomanaʻo.ʻāpana pale (MPU), nā hoʻomanaʻo i hoʻopili ʻia me ka wikiwiki (64 Kbytes o ka polokalamu Flashhoʻomanaʻo, 2 Kbytes o ka ʻikepili EEPROM a me 8 Kbytes o RAM) me kahi ākea ākeai hoʻonui ʻia I/Os a me nā peripheral.
Hāʻawi nā mea STM32L051x6/8 i ka mana mana kiʻekiʻe no kahi ākeahoʻokō. Loaʻa ia me kahi koho nui o nā kumu wati kūloko a me waho, kahika hoʻololi ʻana o ka volta kūloko a me nā ʻano mana haʻahaʻa.
Hāʻawi nā mea STM32L051x6/8 i nā hiʻohiʻona analog, hoʻokahi 12-bit ADC me ka lako.oversampling, ʻelua mea hoʻohālikelike ultra-haʻahaʻa-mana, he nui nā manawa, hoʻokahi manawa mana haʻahaʻa(LPTIM), ʻekolu mau manawa 16-bit kumu nui a hoʻokahi manawa kumu, hoʻokahi RTC a hoʻokahiʻO SysTick hiki ke hoʻohana ʻia e like me nā waihona manawa. He ʻelua ʻīlio kiaʻi lākou, hoʻokahi ʻīlio kiaʻime ka uaki kūʻokoʻa a me ka hiki o ka puka makani a me hoʻokahi ʻīlio kiaʻi puka ma muli o ke kaʻauaki.
Eia kekahi, hoʻokomo nā mea STM32L051x6/8 i ke kamaʻilio maʻamau a me ka holomuanā pilina: a hiki i ʻelua I2C, ʻelua SPI, hoʻokahi I2S, ʻelua USART, kahi UART haʻahaʻa haʻahaʻa (LPUART), .
Hoʻokomo pū ka STM32L051x6/8 i kahi uaki manawa maoli a me kahi pūʻulu o nā papa inoa hoʻopaʻa.e hoʻomau i ka mana ma ke ʻano Standby.
Hoʻohana ʻia nā mana ultra-low-power STM32L051x6/8 mai kahi lako mana 1.8 a 3.6 V.(i lalo i ka 1.65 V i ka mana iho) me BOR a mai kahi lako mana 1.65 a 3.6 V me ka ʻoleKoho BOR. Loaʻa iā lākou ma ke ana wela -40 a +125 °C. He laulāhoʻonohonoho i nā ʻano hana hoʻopakele mana e hiki ai ke hoʻolālā i nā noi haʻahaʻa.
