♠ Mphamvu zotsika kwambiri za 32-bit MCU Arm®-based Cortex®-M0+, mpaka 192KB Flash, 20KB SRAM, 6KB EEPROM, USB, ADC, DACs
Ma ultra-low-power STM32L072xx microcontrollers amaphatikiza mphamvu yolumikiziraUniversal bus (USB 2.0 crystal-less) yokhala ndi Arm Cortex-M0+ yogwira ntchito kwambiri32-bit RISC core ikugwira ntchito pafupipafupi 32 MHz, memory protection unit (MPU), kukumbukira kothamanga kwambiri (mpaka 192 Kbytes of Flash memory memory, 6 Kbytes of dataEEPROM ndi 20 Kbytes ya RAM) kuphatikiza mitundu yambiri ya ma I/O owonjezera ndizotumphukira.
Zipangizo za STM32L072xx zimapereka mphamvu zambiri zogwirira ntchito zosiyanasiyana.
Zimatheka ndi kusankha kwakukulu kwa mawotchi amkati ndi akunja, magetsi amkatikusintha ndi njira zingapo zotsika mphamvu.
Zida za STM32L072xx zimapereka mawonekedwe angapo a analogi, imodzi ya 12-bit ADC yokhala ndi zida.oversampling, ma DAC awiri, zofananira ziwiri zotsika kwambiri, zowerengera nthawi zingapo, mphamvu imodzi yotsikatimer (LPTIM), zowerengera zinayi zopangira 16-bit ndi zowerengera ziwiri zoyambira, RTC imodzi ndi imodzi.SysTick yomwe ingagwiritsidwe ntchito ngati nthawi.Amakhalanso ndi agalu awiri, agalu amodziyokhala ndi wotchi yodziyimira pawokha komanso zenera komanso wowonera zenera limodzi lotengera basikoloko.
Kuphatikiza apo, zida za STM32L072xx zimayika kulumikizana kokhazikika komanso kotsogolamawonekedwe: mpaka ma I2C atatu, ma SPI awiri, I2S imodzi, ma UART anayi, UART yamphamvu yotsika(LPUART), ndi USB yocheperako.Zipangizozi zimapereka mpaka 24 capacitive sensing channelskungowonjezera magwiridwe antchito a touch sensor pa pulogalamu iliyonse.
STM32L072xx imaphatikizanso wotchi yanthawi yeniyeni ndi zolembera zosunga zobwezeretsera zomwe zatsalira.zoyendetsedwa mu Standby mode.
Zida zotsika kwambiri za STM32L072xx zimagwira ntchito kuchokera pa 1.8 mpaka 3.6 V magetsi (pansimpaka 1.65 V pamagetsi pansi) ndi BOR komanso kuchokera ku 1.65 mpaka 3.6 V magetsi opanda BORmwina.Amapezeka mu kutentha kwa -40 mpaka +125 ° C.Magulu athunthu anjira zopulumutsira mphamvu zimalola kupanga mapulogalamu otsika mphamvu.
