Hoʻokomo ʻia nā microcontrollers ultra-low-power STM32L072xx i ka mana hoʻohui o ka bus serial universal (USB 2.0 crystal-less) me ka hana kiʻekiʻe Arm Cortex-M0+ 32-bit RISC core e hana ana ma kahi alapine 32 MHz, kahi ʻāpana pale hoʻomanaʻo ( MPU), nā hoʻomanaʻo hoʻokomo kiʻekiʻe (a hiki i 192 Kbytes o ka hoʻomanaʻo polokalamu Flash, 6 Kbytes o ka ʻikepili EEPROM a me 20 Kbytes o RAM) me kahi ākea ākea o nā I/Os i hoʻonui ʻia a me nā peripheral.Hāʻawi nā polokalamu STM32L072xx i ka mana kiʻekiʻe no ka nui o ka hana.Loaʻa ia me kahi koho nui o nā kumu uaki kūloko a me waho, kahi hoʻololi uila kūloko a me nā ʻano haʻahaʻa haʻahaʻa.Hāʻawi nā mea STM32L072xx i kekahi mau hiʻohiʻona analog, hoʻokahi 12-bit ADC me ka oversampling hardware, ʻelua DAC, ʻelua mau mea hoʻohālikelike ultra-low-power, he nui nā manawa, hoʻokahi manawa haʻahaʻa haʻahaʻa (LPTIM), ʻehā mau manawa 16-bit kumu nui a ʻelua. ʻO ka manawa kumu, hoʻokahi RTC a me hoʻokahi SysTick hiki ke hoʻohana ʻia ma ke ʻano he mau manawa.Hāʻawi pū lākou i ʻelua mau ʻīlio kiaʻi, hoʻokahi kiaʻi me ka uaki kūʻokoʻa a me ka mana puka makani a me hoʻokahi kiaʻi puka makani e pili ana i ka uaki kaʻa.Eia kekahi, hoʻokomo nā mea STM32L072xx i nā pilina kamaʻilio maʻamau a me ka holomua: a hiki i ʻekolu I2C, ʻelua SPI, hoʻokahi I2S, ʻehā USART, kahi UART (LPUART) haʻahaʻa, a me kahi USB ʻaʻole kristal.Hāʻawi nā mea hana a hiki i ka 24 capacitive sensing channel e hoʻohui wale i ka hana touch sensing i kekahi noi.Hoʻokomo pū ka STM32L072xx i kahi uaki manawa maoli a me kahi pūʻulu o nā papa inoa hoʻihoʻi e hoʻomau ʻia i ke ʻano Standby.Hoʻohana ka mana ultra-low-power STM32L072xx mai kahi lako mana 1.8 a 3.6 V (i lalo i ka 1.65 V ma ka mana iho) me BOR a mai kahi lako mana 1.65 a 3.6 V me ka koho ʻole BOR.Loaʻa iā lākou ma ke ana wela -40 a +125 °C.ʻO kahi hoʻonohonoho piha o nā ʻano hoʻopakele mana e hiki ai ke hoʻolālā i nā noi haʻahaʻa haʻahaʻa
