STM32L431RCT6 IC MCU 32BIT 256KB FLASH 64LQFP

Kev piav qhia

Cov khoom siv STM32L431xx yog cov microcontrollers ultra-low-power raws li qhov ua tau zoo ntawm Arm® Cortex®-M4 32-ntsis RISC core ua haujlwm ntawm ntau zaus txog 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-cov ntaub ntawv ua tiav 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 cov khoom siv txuas nrog ob lub tsheb npav APB , ob lub tsheb npav AHB thiab 32-ntsis multi-AHB npav 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 readout 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 sijhawm 16-ntsis qis zog.Tsis tas li ntawd, muaj txog li 21 lub peev xwm ntsuas cov channel.Lawv kuj muaj cov txheej txheem thiab kev sib txuas lus siab heev.• Peb I2Cs • Peb SPIs • Peb USARTs thiab ib qho Low-Power UART.• Ib SAI (Serial Audio Interfaces) • Ib SDMMC • Ib CAN • Ib SWPMI (Single Wire Protocol Master Interface) STM32L431xx ua haujlwm nyob rau hauv -40 txog +85 °C (+105 °C junction), -40 txog +105 ° C (+ 125 ° C hlws ris) thiab -40 rau + 125 ° C (+ 130 ° C hlws ris) qhov kub thiab txias ntawm 1.71 txog 3.6 V fais fab mov.Cov txheej txheem kev txuag hluav taws xob tso cai rau kev tsim cov ntawv siv hluav taws xob tsawg.Qee cov khoom siv hluav taws xob ywj pheej tau txais kev txhawb nqa: analog ywj siab muab tswv yim rau ADC, DAC, OPAMP thiab cov sib piv.VBAT cov tswv yim tso cai rau thaub qab RTC thiab cov ntawv sau npe thaub qab.Tsev neeg STM32L431xx muaj cuaj pob los ntawm 32 rau 100-pin pob.
