Chithunzi cha STM32L552ZET6 IC MCU 32BIT 512KB FLASH 144LQFP

Kufotokozera

Zida za STM32L552xx ndi banja la ma microcontrollers otsika kwambiri (STM32L5 Series) kutengera Arm® Cortex®-M33 32-bit RISC pachimake.Amagwira ntchito pafupipafupi mpaka 110 MHz.Cortex®-M33 pachimake imakhala ndi gawo limodzi lokhalokha loyandama (FPU), lomwe limathandizira malangizo onse a Arm® single-precision-processing data ndi mitundu yonse ya data.Cortex®-M33 pachimake imagwiritsanso ntchito malangizo a DSP (digital signal processing) ndi gawo loteteza kukumbukira (MPU) lomwe limapangitsa chitetezo cha pulogalamuyo.Zipangizozi zimayika zokumbukira zothamanga kwambiri (512 Kbytes of Flash memory ndi 256 Kbytes of SRAM), chowongolera kukumbukira chakunja (FSMC) chokumbukira zokhazikika (pazida zokhala ndi mapini 100 ndi zina zambiri), mawonekedwe a kukumbukira kwa Octo-SPI Flash (omwe akupezeka pamaphukusi onse) komanso kuchuluka kwa ma I/O owonjezera ndi zotumphukira zolumikizidwa ndi mabasi awiri a APB, mabasi awiri a AHB ndi matrix a 32-bit multi-AHB.Zida za STM32L5 Series zimapereka maziko achitetezo omwe amagwirizana ndi zodalirika zokhazikitsidwa ndi chitetezo (TBSA) zofunika kuchokera ku Arm.Amaphatikiza zofunikira zachitetezo kuti agwiritse ntchito boot yotetezedwa, kusungirako deta yotetezedwa, kuyika kwa firmware ndikukweza kotetezedwa.Kusintha kosinthika kwa moyo kumayendetsedwa chifukwa cha magawo angapo achitetezo chowerengera.Kudzipatula kwa hardware ya Firmware kumathandizidwa chifukwa cha zotumphukira zotetezedwa, kukumbukira ndi ma I / Os, komanso kuthekera kosintha zotumphukira ndi kukumbukira ngati "mwayi".Zipangizo za STM32L552xx zimaphatikizira njira zingapo zotetezera zophatikizidwa ndi Flash memory ndi SRAM: chitetezo chowerengera, kulemba chitetezo, malo otetezedwa ndi obisika.
