Chithunzi cha STM32L053R8T6TR IC MCU 32BIT 64KB FLASH 64LQFP

Kufotokozera

Ma ultra-low-power STM32L053x6/8 microcontrollers amaphatikiza mphamvu yolumikizira ya basi yapadziko lonse lapansi (USB 2.0 crystal-less) yokhala ndi Arm Cortex-M0+ 32-bit RISC core yogwira ntchito pafupipafupi 32 MHz, chitetezo kukumbukira. unit (MPU), kukumbukira kothamanga kwambiri (mpaka 64 Kbytes of Flash programme memory, 2 Kbytes of data EEPROM ndi 8 Kbytes of RAM) kuphatikizanso ma I/O owonjezera ndi zotumphukira zake.Zipangizo za STM32L053x6/8 zimapereka mphamvu zambiri zogwirira ntchito zosiyanasiyana.Zimatheka ndi kusankha kwakukulu kwa mawotchi amkati ndi akunja, kusintha kwa magetsi mkati ndi njira zingapo zotsika mphamvu.Zida za STM32L053x6/8 zimakhala ndi mawonekedwe angapo a analogi, imodzi ya 12-bit ADC yokhala ndi ma hardware oversampling, DAC imodzi, zofananira zamphamvu zotsika kwambiri, zowerengera zingapo, timer imodzi yotsika mphamvu (LPTIM), zowerengera zitatu za 16-bit. ndi chowerengera chimodzi chofunikira, RTC imodzi ndi SysTick imodzi yomwe ingagwiritsidwe ntchito ngati zoyambira nthawi.Amakhalanso ndi agalu awiri, wolondera m'modzi wokhala ndi wotchi yodziyimira pawokha komanso zenera komanso wowonera zenera limodzi kutengera wotchi ya basi.Kuphatikiza apo, zida za STM32L053x6/8 zimaphatikizira njira zoyankhulirana zapamwamba komanso zapamwamba: mpaka ma I2C awiri, ma SPI awiri, I2S imodzi, ma UART awiri, UART (LPUART) yamphamvu yotsika, komanso USB yocheperako.Zipangizozi zimapereka mpaka 24 capacitive sensing njira kuti mungowonjezera magwiridwe antchito pakugwiritsa ntchito kulikonse.STM32L053x6/8 imaphatikizanso wotchi yanthawi yeniyeni ndi zolembera zosunga zobwezeretsera zomwe zimakhalabe zoyendetsedwa mu Standby mode.Pomaliza, wowongolera wawo wa LCD wophatikizika ali ndi jenereta yamagetsi ya LCD yomwe imalola kuyendetsa mpaka 8 ma LCD ophatikizika mosiyanitsa osadalira mphamvu zamagetsi.Zida zotsika kwambiri za STM32L053x6/8 zimagwira ntchito kuchokera pamagetsi a 1.8 mpaka 3.6 V (kutsika mpaka 1.65 V pamagetsi pansi) ndi BOR komanso kuchokera ku 1.65 mpaka 3.6 V magetsi opanda njira ya BOR.Amapezeka mu kutentha kwa -40 mpaka +125 ° C.Mitundu yambiri yopulumutsira mphamvu imalola kupanga mapulogalamu otsika mphamvu.
