♠ ʻO Cortex®-M0+ e pili ana i ka mana loa-haʻahaʻa loa 32-bit MCU Arm®, a hiki i 192KB Flash, 20KB SRAM, 6KB EEPROM, USB, ADC, DACs
Hoʻokomo nā microcontrollers ultra-low-power STM32L072xx i ka mana hoʻohui oke kaʻaahi serial universal (USB 2.0 crystal-less) me ka Arm Cortex-M0+ kiʻekiʻe.32-bit RISC core e hana ana ma kahi alapine 32 MHz, kahi ʻāpana hoʻomanaʻo hoʻomanaʻo (MPU), kiʻekiʻe kiʻekiʻe i hoʻokomo ʻia nā hoʻomanaʻo (a hiki i 192 Kbytes o ka hoʻomanaʻo polokalamu Flash, 6 Kbytes o ka ʻikepili.EEPROM a me 20 Kbytes o RAM) me ka laulā nui o nā I/O i hoʻonui ʻia a mepilipili.
Hāʻawi nā polokalamu STM32L072xx i ka mana kiʻekiʻe no ka nui o ka hana.
Loaʻa ia me kahi koho nui o nā kumu uʻi kūloko a me waho, kahi volta kūlokohoʻololi a me kekahi mau ʻano mana haʻahaʻa.
Hāʻawi nā mea STM32L072xx i nā hiʻohiʻona analog, hoʻokahi 12-bit ADC me ka lakooversampling, ʻelua DAC, ʻelua mea hoʻohālikelike ultra-haʻahaʻa-mana, mau manawa, hoʻokahi mana haʻahaʻa.timer (LPTIM), ʻehā mau manawa 16-bit kumu nui a me ʻelua 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 STM32L072xx i ke kamaʻilio maʻamau a me ka holomuanā pilina: a hiki i ʻekolu I2C, ʻelua SPI, hoʻokahi I2S, ʻehā USART, kahi UART mana haʻahaʻa.(LPUART), a me ka USB ʻaʻole kristal.Hāʻawi nā mea hana a hiki i ka 24 capacitive sensing channele hoʻohui wale i ka hana hoʻopā i kekahi noi.
Hoʻokomo pū ka STM32L072xx i kahi uaki manawa maoli a me kahi pūʻulu o nā papa inoa hoʻopaʻa i koehana ʻia ma ke ʻano Standby.
Hoʻohana ʻia nā polokalamu STM32L072xx ultra-low-power mai kahi lako mana 1.8 a 3.6 V (laloi ka 1.65 V i ka mana iho) me BOR a mai kahi lako mana 1.65 a i 3.6 V me ka ʻole o BORkoho.Loaʻa iā lākou ma ka -40 a +125 °C ka wela wela.He pūʻulu piha oHiki i nā ʻano hana mālama mana ke hoʻolālā i nā noi haʻahaʻa.
