♠ Izilawuli ezincane ze-TMS320F2802x
Izilawuli ezincane ze-C2000™ 32-bit zilungiselelwe ukucutshungulwa, ukuzwa, nokwenza kusebenze ukuze kuthuthukiswe ukusebenza kwe-loop evaliwe ezinhlelweni zokusebenza zokulawula isikhathi sangempela ezifana namadrayivu ezimoto zezimboni; ama-solar inverters namandla edijithali; izimoto zikagesi nezokuthutha; isilawuli semoto; kanye nokucutshungulwa kokuzwa kanye namasignali. Ulayini we-C2000 uhlanganisa ama-MCU okusebenza kwe-Premium kanye nama-MCU okusebenza kwe-Entry.
Umndeni we-F2802x wama-microcontrollers unikeza amandla engqikithi ye-C28x ahlanganiswe nama-peripherals okulawula adidiyelwe kakhulu kumadivayisi anenani eliphansi lephini. Lo mndeni uhambisana nekhodi nekhodi yangaphambilini esekwe ku-C28x, futhi uhlinzeka ngezinga eliphezulu lokuhlanganiswa kwe-analog.
I-voltage regulator yangaphakathi ivumela ukusebenza kwesitimela esisodwa. Izithuthukisi zenziwe ku-HRPWM ukuze kuvunyelwe ukulawula okukabili (i-frequency modulation). Iziqhathaniso ze-analogi ezinezithenjwa zangaphakathi ze-10-bit zengeziwe futhi zingahanjiswa ngokuqondile ukuze kulawulwe imiphumela ye-PWM. I-ADC iguqula isuka ku-0 iye ku-3.3-V ibanga lesilinganiso esigcwele esigxilile futhi isekela amareferensi we-ratio-metric VREFHI/VREFLO. Isixhumi esibonakalayo se-ADC senzelwe i-overhead ephansi nokubambezeleka.
