♠ Ultra-low-power Arm® Cortex®-M4 32-ntsis MCU + FPU, 100 DMIPS, mus txog 1 MB Flash, 320 KB SRAM, USB OTG FS, suab, sab nraud SMPS
Cov khoom siv STM32L496xx 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 STM32L496xx embed high-speed nco (txog 1 Mbyte ntawm Flash nco, 320 Kbyte ntawm SRAM), hloov tau yooj yim sab nraud lub cim xeeb tswj (FSMC) rau kev nco zoo li qub (rau cov khoom siv nrog pob ntawm 100 tus pins thiab ntau dua), Quad SPI Flash nco interface (muaj nyob rau ntawm txhua pob khoom txuas ntxiv) thiab kev txuas ntxiv rau ob qho tib si. APB tsheb npav, ob lub tsheb npav AHB thiab 32-ntsis multi-AHB npav matrix.
Cov khoom siv STM32L496xx embed ob peb kev tiv thaiv mechanisms rau embedded Flash nco thiab SRAM: nyeem ntawv tiv thaiv, sau kev tiv thaiv, proprietary code readout tiv thaiv thiab Firewall.
Cov cuab yeej muaj txog peb qhov ceev 12-ntsis ADCs (5 Msps), ob qhov sib piv, ob lub tshuab ua haujlwm, ob lub DAC raws, ib qho kev siv hluav taws xob sab hauv, lub zog qis RTC, ob lub hom phiaj 32-ntsis timer, ob lub hom phiaj 16-ntsis PWM timers mob siab rau kev tswj lub cev muaj zog, xya lub hom phiaj 16-ntsis timers 16-ntsis, thiab ob lub hom phiaj Cov cuab yeej txhawb nqa plaub lub lim dej rau sab nraud sigma delta modulators (DFSDM).
Tsis tas li ntawd, muaj txog li 24 lub peev xwm ntsuas cov channel. Cov khoom siv kuj tseem muaj kev sib xyaw ua ke ntawm LCD tsav tsheb 8x40 lossis 4x44, nrog rau kev hloov pauv sab hauv.
Lawv kuj tseem muaj cov qauv kev sib txuas lus zoo tshaj plaws, uas yog plaub I2Cs, peb SPIs, peb USARTs, ob UARTs thiab ib qho Low-Power UART, ob SAIs, ib SDMMC, ob CANs, ib USB OTG full-speed, ib SWPMI (ib leeg hlau raws tu qauv interface), lub koob yees duab interface thiab ib tug DMA2D maub los.
STM32L496xx ua haujlwm nyob rau hauv -40 txog +85 °C (+105 °C hlws ris), -40 txog +125 °C (+130 ° C hlws ris) kub li ntawm 1.71 mus rau 3.6 VDD fais fab mov thaum siv sab hauv LDO regulator thiab ib tug 1.05 mus rau 1122V fais fab mov VDD. Cov txheej txheem kev txuag hluav taws xob ua kom muaj peev xwm tsim tau 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, OPAMPs thiab cov neeg sib piv, 3.3 V siab muab cov tswv yim rau USB thiab mus txog 14 I / Os tuaj yeem muab nws tus kheej mus txog 1.08 V. Ib VBAT cov tswv yim ua rau nws muaj peev xwm thaub qab RTC thiab cov ntaub ntawv 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 STM32L496xx muaj xya pob khoom los ntawm 64-pin rau 169-pin pob.
