Chithunzi cha STM32L021D4P6 IC MCU 32BIT 16KB FLASH 14TSSOP

Kufotokozera

Banja la STM32L021x4 lamphamvu kwambiri-low-power limaphatikizapo Arm® Cortex®-M0+ 32-bit RISC core yomwe imagwira ntchito pafupipafupi 32 MHz, kukumbukira kothamanga kwambiri (16 Kbytes of Flash program memory, 512 bytes of data. EEPROM ndi 2 Kbytes of RAM) kuphatikiza ma I/O owonjezera ndi zotumphukira.Zipangizo za STM32L021x4 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 STM32L021x4 zimakhala ndi mawonekedwe angapo a analogi, imodzi ya 12-bit ADC yokhala ndi ma hardware oversampling, ma ultra-low-power comparator, AES, zowerengera zingapo, timer yotsika mphamvu (LPTIM), zowerengera zitatu za 16-bit, RTC imodzi. ndi SysTick imodzi yomwe ingagwiritsidwe ntchito ngati 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 STM32L021x4 zimayika njira zoyankhulirana zapamwamba komanso zapamwamba: I2C imodzi, SPI imodzi, UART imodzi, ndi UART (LPUART) yamphamvu yotsika.STM32L021x4 imaphatikizanso wotchi yanthawi yeniyeni ndi zolembera zosunga zobwezeretsera zomwe zimakhalabe zoyendetsedwa mu Standby mode.Zida zotsika kwambiri za STM32L021x4 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.
