Taw qhia rau Tsawg- zog MCU nti
Tsawg- lub zog MCU nti yog embedded processing chips tshwj xeeb uas tsim los rau qis - fais fab daim ntawv thov scenarios. Thaum khaws cov kev suav thiab kev tswj cov peev txheej, cov chips leverage architectural optimization thiab tshiab zog tswj tsim kom txo tau hwj chim noj nyob rau hauv ob qho tib si nquag ua hauj lwm thiab standby hom. Lawv ua haujlwm tseem ceeb hauv kev tswj cov khoom siv roj teeb -lub zog lossis lub zog- sau cov ntawv thov xws li Is Taws Nem ntawm Yam (IoT), cov cuab yeej siv tau zoo thiab kev paub txog kev lag luam.
Tsawg- zog MCU nti Tsim Technology
Los ntawm qhov kev xav ntawm kev tsim qauv, lub zog ua kom zoo rau Tsawg- lub zog MCU nti npog tag nrho cov nti architecture. Feem ntau qis - zog MCUs yog tsim los ntawm ARM Cortex-M series qis- fais fab cores (xws li Cortex-M0+ thiab Cortex-M33F). Cov cores no ib txwm siv txoj kev tsim cov raj xa dej kom yooj yim, thiab tuaj yeem nkag mus rau qis- hom fais fab los ntawm kev nkag mus rau cov moos ntawm cov khoom siv tsis siv. Lub caij no, cov chips koom ua ke ntau- theem kev tswj fais fab hom. Ntxiv rau hom kev ua haujlwm ib txwm muaj, lawv feem ntau yog nruab nrog ntau theem ntawm qis- hom fais fab suav nrog kev pw tsaug zog, pw tsaug zog, standby thiab lub zog- down. Cov khoom siv hluav taws xob tsis sib xws tuaj yeem raug cuam tshuam los ntawm ntau hom. Tshwj xeeb, kev siv hluav taws xob hauv lub hwj chim- hom qis tuaj yeem ncav cuag qis li nA qib, qhov twg tsuas yog lub sijhawm tiag tiag - moos lossis sawv- cov pins tseem ua haujlwm, thiab kev ua haujlwm ib txwm tuaj yeem rov qab sai sai thaum tau txais cov teeb liab tshwm sim. Tsis tas li ntawd, qib siab qis- cov txheej txheem CMOS feem ntau tau txais los ntawm kev tsim cov chips kom txo qis kev siv hluav taws xob los ntawm cov dej ntws zoo li qub. Qee cov khoom lag luam kuj tseem txhawb nqa lub zog hluav taws xob thiab qhov ntsuas zaus, uas kho cov haujlwm zaus thiab cov tub ntxhais hluav taws xob raws li kev ua haujlwm, txhawm rau ua kom tau raws li qhov yuav tsum tau ua thaum tsis txhob siv hluav taws xob tsis zoo.
Qhov tshwj xeeb ntawm qis- zog MCU chips
MSPM0L111x microcontroller (MCU) yog ib qho kev sib xyaw ua ke ultra- qis- zog 32-ntsis MCU khoom hauv qab MSP series. Tsim los ntawm kev txhim kho Arm Cortex-M0+ core platform, nws muaj qhov ua haujlwm siab tshaj plaws ntawm 32MHz. Tus nqi no - optimized MCU series integrates siab -kev ua tau zoo analog peripherals, muab kev ua tau zoo tsis muaj zog, txhawb kev khiav hauj lwm kub ntawm -40℃mus rau 125 degree, thiab tuaj yeem ua haujlwm ruaj khov ntawm cov khoom siv hluav taws xob xws li 1.62V txog 3.6V.
Cov cuab yeej ua ke ua ke ua - hauv Kev Kho Cov Cai (ECC), thiab tau nruab nrog txog li 128KB ntawm embedded flash nco thiab txog li 16KB ntawm SRAM. Lub flash nco tau muab faib ua ob lub tsev txhab nyiaj ywj pheej, txhawb nqa hauv - teb firmware hloov tshiab nrog rau qhov chaw nyob sib pauv ntawm ob lub tsev txhab nyiaj.
Cov MCU series no siv cov haujlwm suav nrog kev ruaj ntseg khau raj, ruaj ntseg hauv - teb firmware hloov tshiab, IP tiv thaiv (tsuas yog- tsuas yog nco) thiab qhov tseem ceeb cia los ntawm kev hloov kho kev ruaj ntseg. Nws kuj tseem muab cov khoom siv nrawm nrawm rau ntau hom AES symmetric cipher hom thiab TRNG entropy qhov chaw, thiab nws cov qauv kev ruaj ntseg tam sim no tseem tos Arm® PSA Qib 1 daim ntawv pov thawj.
Cov MCU series no ua ke nrog lub siab - nrawm ntawm -chip oscillator nrog qhov tseeb txog li ± 1.2%, tshem tawm qhov yuav tsum tau muaj rau sab nraud siv lead ua. Nws kuj tseem muaj 3-channel DMA, 16-ntsis / 32-ntsis CRC accelerator, thiab ntau yam siab-kev ua tau zoo analog peripherals, suav nrog 12-ntsis 1.68Msps ADC nrog rau kev teeb tsa kev siv hluav taws xob sab hauv, nrog rau qhov ntsuas kub ntawm conf. Nws tseem tau nruab nrog cov khoom siv ntse ntse: ib qho 16-ntsis advanced tswj timer, ob lub 16-ntsis lub hom phiaj timers, ib lub hom phiaj timer nrog quadrature pab tswv yim, lub qhov rais saib xyuas lub sijhawm, thiab ntau yam kev sib txuas lus peripherals (ib qho I2C, ib SPI, ob UARTs, nrog rau ib qho UART txhawb nqa LIN).
