ʻO nā polokalamu STM32L552xx he ʻohana microcontrollers ultra-low-power (STM32L5 Series) e pili ana i ka hana kiʻekiʻe Arm® Cortex®-M33 32-bit RISC core.Hana lākou ma ke alapine a hiki i 110 MHz.Hāʻawi ka Cortex®-M33 core i kahi ʻāpana floating-point (FPU), e kākoʻo ana i nā ʻōlelo aʻoaʻo hoʻoili ʻikepili hoʻokahi Arm® a me nā ʻano ʻikepili āpau.Hoʻokomo pū ka Cortex®-M33 core i kahi pūʻulu piha o DSP (digital signal processing) aʻoaʻo a me kahi ʻāpana pale hoʻomanaʻo (MPU) e hoʻonui ai i ka palekana o ka noi.Hoʻokomo kēia mau mea i nā mea hoʻomanaʻo kiʻekiʻe (512 Kbytes o ka hoʻomanaʻo Flash a me 256 Kbytes o SRAM), kahi mea hoʻomanaʻo hoʻomanaʻo waho maʻalahi (FSMC) no nā hoʻomanaʻo static (no nā mea me nā pūʻolo o 100 mau pine a keu aku), kahi kikowaena hoʻomanaʻo Octo-SPI Flash. (loaʻa ma nā pūʻolo a pau) a me ka laulā nui o nā I/Os i hoʻonui ʻia a me nā peripheral i hoʻopili ʻia i ʻelua mau kaʻa APB, ʻelua mau pahi AHB a me kahi 32-bit multi-AHB matrix.Hāʻawi nā polokalamu STM32L5 Series i ke kahua palekana e pili ana i nā koi hilinaʻi hilinaʻi palekana (TBSA) mai Arm.Hoʻokomo lākou i nā hiʻohiʻona palekana e pono ai e hoʻokō i kahi pahu paʻa, mālama i ka ʻikepili paʻa, hoʻonohonoho paʻa paʻa a me ka hoʻonui ʻana i ka firmware.Hoʻokele ʻia ka pōʻai ola maʻalahi me nā pae he nui o ka pale heluhelu.Kākoʻo ʻia ka hoʻokaʻawale ʻana i nā lako firmware e hoʻomaikaʻi i nā peripherals paʻa, hoʻomanaʻo a me I / Os, a me ka hiki ke hoʻonohonoho i nā peripherals a me nā hoʻomanaʻo ma ke ʻano he "pono".Hoʻokomo nā polokalamu STM32L552xx i kekahi mau mea pale no ka hoʻomanaʻo Flash i hoʻokomo ʻia a me SRAM: pale heluhelu, pale kākau, palekana a hūnā ʻia nā wahi palekana.
