Chithunzi cha STM32L072CBT6 IC MCU 32BIT 128KB FLASH 48LQFP

Kufotokozera

Ma ultra-low-power STM32L072xx 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, gawo loteteza kukumbukira ( MPU), kukumbukira kothamanga kwambiri (mpaka 192 Kbytes of Flash memory memory, 6 Kbytes of data EEPROM ndi 20 Kbytes of RAM) kuphatikiza mitundu yambiri yama I/Os ndi zotumphukira.Zipangizo za STM32L072xx 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 STM32L072xx zimakhala ndi mawonekedwe angapo a analogi, imodzi ya 12-bit ADC yokhala ndi ma hardware oversampling, ma DAC awiri, ofananitsa amphamvu kwambiri, zowerengera zingapo, timer imodzi yotsika mphamvu (LPTIM), zowerengera zinayi za 16-bit ndi ziwiri. Basic timer, 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 STM32L072xx zimaphatikizira njira zolumikizirana komanso zoyankhulirana zapamwamba: mpaka ma I2C atatu, ma SPI awiri, I2S imodzi, ma UART anayi, UART (LPUART) yamphamvu yotsika, ndi USB yocheperako.Zipangizozi zimapereka mpaka 24 capacitive sensing njira kuti mungowonjezera magwiridwe antchito pakugwiritsa ntchito kulikonse.STM32L072xx imaphatikizanso wotchi yanthawi yeniyeni ndi zolembera zosunga zobwezeretsera zomwe zimakhalabe zoyendetsedwa mu Standby mode.Zida zotsika kwambiri za STM32L072xx zimagwira ntchito kuchokera ku 1.8 mpaka 3.6 V magetsi (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
