Iwo ekupedzisira-akaderera-simba STM32L072xx microcontrollers anosanganisira iyo yekubatanidza simba reiyo yepasirese serial bhazi (USB 2.0 kristaro-shoma) ine yepamusoro-inoshanda Arm Cortex-M0+32-bit RISC musimboti unoshanda pane 32 MHz frequency, memory yekudzivirira unit (MPU), yakadzika yakadzika ndangariro (kusvika 192 Kbytes yeFlash program memory, 6 Kbytes yedata.EEPROM uye 20 Kbytes ye RAM) pamwe nehupamhi hwakakura hwekuvandudza I/Os uyeperipherals.
Iyo STM32L072xx zvishandiso zvinopa simba rakanyanya kushanda kune akasiyana siyana ekuita.
Inowanikwa nesarudzo yakakura yemukati uye yekunze wachi masosi, voltage yemukatikugadzirisa uye akati wandei-yakaderera-simba modes.
Iyo STM32L072xx zvishandiso zvinopa akati wandei analog maficha, imwe 12-bit ADC ine Hardware.oversampling, maDAC maviri, maviri ekupedzisira-akaderera-simba anoenzanisa, akati wandei nguva, imwe yakaderera-simbatimer (LPTIM), ina general-chinangwa 16-bit timer uye maviri ekutanga timer, imwe RTC uye imwe.SysTick iyo inogona kushandiswa senge nguva. Vanosanganisirawo imbwa mbiri, imbwa imweine yakazvimirira wachi uye hwindo kugona uye imwe hwindo watchdog yakavakirwa bhaziwachi.
Uyezve, iyo STM32L072xx michina inomisikidza yakajairwa uye yepamberi kutauriranamainterfaces: anosvika matatu maI2C, maviri maSPI, imwe I2S, mana UART, yakaderera-simba UART(LPUART), uye nekristaro-isina USB. Zvishandiso zvinopa kusvika ku24 capacitive sensing chiteshikuti ungowedzera kubata inonzwa kushanda kune chero application.
Iyo STM32L072xx inosanganisirawo chaiyo-nguva wachi uye seti yezvinyorwa zvekuchengetedza zvinosara.powered in Standby mode.
Iyo yekupedzisira-yakaderera-simba STM32L072xx zvishandiso zvinoshanda kubva pa1.8 kusvika 3.6 V magetsi ekupa (pasikusvika ku1.65 V pamagetsi pasi) neBOR uye kubva pa1.65 kusvika ku3.6 V magetsi asina BORsarudzo.
