♠ Ultra-low-power Arm® Cortex®-M4 32-ntsis MCU + FPU, 100DMIPS, mus txog 512KB Flash, 160KB SRAM, analog, suab
Cov khoom siv STM32L451xx yog ultra-low-power microcontrollers raws li qhov ua tau zoo 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-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 STM32L451xx embed high-speed nco (Flash nco txog 512 Kbyte, 160 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 AHB2 thiab ntau lub tsheb npav.
Cov khoom siv STM32L451xx embed ob peb kev tiv thaiv mechanisms rau embedded Flash nco thiab SRAM: nyeem ntawv tiv thaiv, sau kev 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, ib qho DAC channel, ib qho hluav taws xob 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 hwj chim-16-ntsis timers.
Tsis tas li ntawd, muaj txog li 21 lub peev xwm ntsuas cov channel.
Lawv kuj muaj cov qauv kev sib txuas lus zoo tshaj plaws, uas yog plaub I2Cs, peb SPIs, peb USARTs, ib UART thiab ib qho Low-Power UART, ib SAI, ib SDMMC, ib qho CAN.
STM32L451xx ua haujlwm nyob rau hauv -40 txog +85 ° C (+105 ° C hlws ris) thiab -40 txog +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 ua kom muaj peev xwm 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. Ib VBAT cov tswv yim ua rau nws muaj peev xwm backup RTC thiab cov npe thaub qab.
Tsev neeg STM32L451xx muaj rau pob khoom los ntawm 48 mus rau 100-pin pob.
