Fa'amatalaga
O le laina avanoa ultra-low-power STM32L021x4 aiga e aofia ai le Arm® Cortex®-M0+ 32-bit RISC autu o loʻo faʻaogaina i le 32 MHz, faʻamanatuga faʻapipiʻi maualuga (16 Kbytes o le Flash polokalame manatua, 512 bytes o faʻamaumauga. EEPROM ma le 2 Kbytes o le RAM) faʻatasi ai ma le tele o le faʻaleleia o I/Os ma peripheral.O masini STM32L021x4 e maua ai le malosi maualuga mo le tele o fa'atinoga.E maua i se filifiliga tele o puna'oa i totonu ma fafo uati, se fetuutuunai voltage i totonu ma le tele o auala maualalo.O masini STM32L021x4 e ofoina atu le tele o foliga fa'atusa, tasi le 12-bit ADC fa'atasi ai ma le fa'aogaina o meafaigaluega, lua fa'atusatusaga ultra-maualalo-mana, AES, tele taimi, tasi taimi maualalo-malosi (LPTIM), tolu fa'amoemoe lautele 16-bit timers, tasi RTC ma le tasi SysTick e mafai ona faʻaaogaina e fai ma faʻamaumauga taimi.O lo'o fa'aalia fo'i ni ta'ifau e lua, tasi ta'ifau e iai le uati tuto'atasi ma le fa'amalama fa'amalama ma le tasi ta'i fa'amalama e fa'atatau i le uati pasi.E le gata i lea, o masini STM32L021x4 o loʻo faʻapipiʻiina ai fesoʻotaʻiga masani ma fesoʻotaʻiga: tasi le I2C, tasi le SPI, tasi le USART, ma le UART maualalo (LPUART).O le STM32L021x4 o lo'o aofia ai fo'i se uati moni ma se seti o tusi resitala o lo'o tumau pea le malosi i le tulaga Standby.O masini STM32L021x4 ultra-maualalo e faagaoioia mai le 1.8 i le 3.6 V eletise (lalo i le 1.65 V i lalo) ma le BOR ma mai le 1.65 i le 3.6 V le eletise e aunoa ma le BOR filifiliga.E maua i le -40 i le +125 °C le vevela.O se seti atoatoa o auala fa'aola fa'aola e mafai ai ona fa'ata'atia le fa'aogaina o fa'aoga maualalo.
