♠ Ultra-low-power Arm® Cortex®-M4 32-ntsis MCU + FPU, 100DMIPS, mus txog 256KB Flash, 64KB SRAM, analog, suab
Cov khoom siv STM32L431xx yog ultra-low-power microcontrollers raws li kev ua haujlwm siab Arm® Cortex®-M4 32-ntsis RISC core ua haujlwm ntawm qhov zaus ntawm 80 MHz. Lub Cortex-M4 core nta Floating point unit (FPU) ib qho kev txiav txim siab uas txhawb nqa tag nrho Arm® ib leeg-txhim kho cov ntaub ntawv-ua cov lus qhia thiab hom ntaub ntawv. Nws kuj tseem siv tag nrho DSP cov lus qhia thiab lub cim xeeb tiv thaiv (MPU) uas txhim kho daim ntawv thov kev ruaj ntseg.
Cov khoom siv STM32L431xx embed high-speed nco (Flash nco txog 256 Kbyte, 64 Kbyte ntawm SRAM), Quad SPI flash nco interface (muaj nyob rau txhua pob) thiab ntau yam kev txhim kho I/Os thiab peripherals txuas nrog ob lub tsheb npav APB, ob lub tsheb npav AHB-2 matrix.
Cov khoom siv STM32L431xx embed ob peb kev tiv thaiv mechanisms rau embedded Flash nco thiab SRAM: nyeem ntawv tiv thaiv, sau ntawv tiv thaiv, proprietary code nyeem ntawv tiv thaiv thiab Firewall.
Cov cuab yeej muab ceev ceev 12-ntsis ADC (5 Msps), ob qhov sib piv, ib qho kev ua haujlwm amplifier, ob lub DAC raws, ib qho kev siv hluav taws xob sab hauv, lub hwj chim qis RTC, ib lub hom phiaj 32-ntsis timer, ib qho 16-ntsis PWM timer mob siab rau kev tswj lub cev muaj zog, plaub lub hom phiaj 16-ntsis timers, thiab ob lub sij hawm tsawg-16-ntsis.
Tsis tas li ntawd, muaj txog li 21 lub peev xwm ntsuas cov channel.
