♠ Ultra-low-power Arm® Cortex®-M4 32-bit MCU+FPU, 100DMIPS, Flash nganti 256KB, SRAM 64KB, analog, audio
Piranti STM32L431xx minangka mikrokontroler ultra-rendah adhedhasar inti RISC Arm® Cortex®-M4 32-bit kinerja dhuwur sing beroperasi kanthi frekuensi nganti 80 MHz. Inti Cortex-M4 nduweni presisi tunggal Floating point unit (FPU) sing ndhukung kabeh instruksi pangolahan data presisi tunggal Arm® lan jinis data. Iku uga ngleksanakake pesawat lengkap instruksi DSP lan unit pangayoman memori (MPU) kang nambah keamanan aplikasi.
Piranti STM32L431xx ngemot memori-kacepetan dhuwur (memori lampu kilat nganti 256 Kbyte, 64 Kbyte SRAM), antarmuka memori flash Quad SPI (kasedhiya ing kabeh paket) lan sawetara ekstensif I / Os lan peripheral sing disambungake menyang rong bus APB, loro bus AHB lan matriks multi-AHB 32-bit.
Piranti STM32L431xx ngemot sawetara mekanisme proteksi kanggo memori Flash lan SRAM sing dipasang: proteksi maca, proteksi nulis, proteksi maca kode lan Firewall.
Piranti kasebut nyedhiyakake ADC 12-bit (5 Msps) kanthi cepet, loro komparator, siji amplifier operasional, rong saluran DAC, buffer referensi voltase internal, RTC kurang daya, siji timer 32-bit tujuan umum, siji timer PWM 16-bit khusus kanggo kontrol motor, papat timer 16-bit tujuan umum, lan loro timer 16-bit kurang.
