♠ Ultra-low-power Arm® Cortex®-M4 32-ntsis MCU + FPU, 100DMIPS, mus txog 128KB Flash, 40KB SRAM, analog, ext. SMPS
Cov khoom siv STM32L412xx 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 STM32L412xx embed high-speed nco (Flash nco txog 128 Kbyte, 40 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 matrix thiab 3.
Cov khoom siv STM32L412xx 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 khoom siv muaj ob lub nrawm 12-ntsis ADC (5 Msps), ob qhov sib piv, ib qho kev ua haujlwm amplifier, lub zog 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 16-ntsis low-power timers.
Tsis tas li ntawd, muaj txog 12 capacitive sensing channels.
Lawv kuj muaj cov qauv kev sib txuas lus zoo tshaj plaws, uas yog peb I2Cs, ob lub SPIs, peb USARTs thiab ib qho Low-Power UART, ib qho USB puv-ceev ntaus ntawv siv lead ua tsawg dua.
STM32L412xx ua haujlwm nyob rau hauv -40 txog +85 °C (+105 ° C hlws ris) thiab -40 txog +125 °C (+130 ° C hlws ris) kub yog li ntawm 1.71 txog 3.6 VDD fais fab mov thaum siv sab hauv LDO regulator thiab siv 1.00 rau 112V fais fab mov thaum siv SM. 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, OPAMP thiab sib piv. Ib VBAT cov tswv yim ua rau nws muaj peev xwm backup RTC thiab cov npe thaub qab. Dedicated VDD12 cov khoom siv hluav taws xob tuaj yeem siv los hla lub LDO regulator thaum txuas nrog SMPS sab nraud.
Tsev neeg STM32L412xx muaj rau pob khoom los ntawm 32 mus rau 64-pin pob.
