TMS320F28021PTT Tshiab Thiab Thawj Tus Kheej Tus Kheej Cov Khoom Siv Ua Ke Circuit Court Ic Chip
Internal voltage regulator tso cai rau ib leeg-rail khiav lag luam.Kev txhim kho tau ua rau HRPWM tso cai rau kev tswj hwm ob sab (frequency modulation).Analog piv nrog 10-ntsis cov ntaub ntawv tau muab ntxiv thiab tuaj yeem xa ncaj qha los tswj PWM cov zis.ADC hloov los ntawm 0 mus rau 3.3-V tsau tag nrho cov nplai ntau thiab txhawb kev sib piv-metric VREFHI / VREFLO cov lus qhia.ADC interface tau ua kom zoo rau cov nyiaj siv ua haujlwm qis thiab latency.

Kev faib tawm
Raws li lub luag haujlwm ua los ntawm MCU hauv nws txoj haujlwm, feem ntau yog cov hauv qab no ntawm microcontrollers.
Instruction Controller
Tus tswj kev qhia yog ib feem tseem ceeb ntawm tus maub los, nws yuav tsum ua kom tiav cov haujlwm ntawm kev nqa cov lus qhia, tshuaj xyuas cov lus qhia, thiab lwm yam, thiab tom qab ntawd muab nws mus rau chav ua haujlwm (ALU lossis FPU) kom ua tiav, thiab tseem tsim qhov chaw nyob. ntawm cov lus qhia tom ntej.
Timing Controller
Lub luag haujlwm ntawm tus tswj lub sijhawm yog los muab kev tswj xyuas cov cim qhia rau txhua qhov kev qhia hauv kev txiav txim raws sijhawm.Lub sij hawm maub los muaj lub tshuab hluav taws xob moos thiab lub tshuab hluav taws xob ntau lub ntsiab lus, qhov twg lub tshuab hluav taws xob moos yog lub teeb liab mem tes ruaj khov los ntawm quartz siv lead ua oscillator, uas yog lub ntsiab CPU zaus, thiab lub ntsiab lus multiplier txhais tau tias muaj pes tsawg zaus lub ntsiab CPU zaus. yog lub cim xeeb zaus (bus zaus).
Bus Controller
Lub tsheb npav maub los yog siv los tswj cov tsheb npav sab hauv thiab sab nraud ntawm CPU, suav nrog lub npav chaw nyob, cov ntaub ntawv npav, tsheb npav, thiab lwm yam.
Interrupt Controller
Tus maub los cuam tshuam yog siv los tswj ntau yam kev cuam tshuam kev thov, thiab raws li qhov tseem ceeb ntawm kev cuam tshuam kev thov queue, ib qho los ntawm ib qho mus rau CPU ua Cov haujlwm yooj yim ntawm tus maub los Cov haujlwm yooj yim ntawm tus tswj cov cuab yeej.
TI MCUs Design Concepts
Peb cov ntaub ntawv sib txawv ntawm 16- thiab 32-ntsis microcontrollers (MCUs) nrog rau lub sijhawm tswj lub peev xwm thiab kev sib koom ua ke siab-precision analog tau ua kom zoo rau kev lag luam thiab kev siv tsheb.Rov qab los ntawm ntau xyoo ntawm kev txawj ntse thiab kev kho vajtse thiab software tshiab, peb MCUs tuaj yeem ua tau raws li qhov xav tau ntawm txhua tus qauv tsim thiab pob nyiaj siv.
Raws li cov ntaub ntawv tam sim no tau muab rau hauv TI lub vev xaib official, TI's MCUs tuaj yeem faib dav rau peb tsev neeg hauv qab no.
