Incazelo ye-TMS320LF2407A
Amadivayisi we-TMS320LF240xA kanye ne-TMS320LC240xA, amalungu amasha e-TMS320C24x™;ukukhiqizwa kwezilawuli ze-digital signal processor (DSP), ziyingxenye ye-TMS320C2000™;isiteji sama-Fixed-point DSPs.Amadivayisi angu-240xA ahlinzeka nge-TMS320™ ethuthukisiwe;Idizayini yezakhiwo ye-DSP ye-C2xx core CPU yezindleko eziphansi, amandla aphansi, namandla okucubungula okusebenza okuphezulu.Izingxenye ezizungezile ezimbalwa ezithuthukisiwe, ezilungiselelwe izinjini zedijithali kanye nezinhlelo zokusebenza zokulawula ukunyakaza, zihlanganisiwe ukuze zinikeze isilawuli sangempela se-DSP ye-chip eyodwa.Ngenkathi ikhodi ihambisana ne-C24x™ ekhona;Amadivayisi wesilawuli se-DSP, i-240xA inikezela ngokusebenza okwengeziwe kokucubungula (40 MIPS) nezinga eliphezulu lokuhlanganiswa kwe-peripheral.Bona isigaba Sesifinyezo Sedivayisi ye-TMS320x240xA ukuze uthole izici eziqondene nedivayisi.
Isizukulwane se-240xA sinikeza inqwaba yosayizi benkumbulo nezinto ezisetshenziswayo ezihlukene ezenzelwe ukuhlangabezana nenani elithile/amaphoyinti okusebenza adingwa izinhlelo zokusebenza ezihlukahlukene.Amadivayisi we-Flash angafika kumagama angu-32K anikezela ngesisombululo esingabizi esihlelekayo sokukhiqiza ivolumu.Amadivayisi angu-240xA anikeza isici esisekelwe kuphasiwedi "sokuphepha kwekhodi" esiwusizo ekuvimbeleni ukuphindwaphindwa okungagunyaziwe kwekhodi yobunikazi egcinwe ku-chip Flash/ROM.Qaphela ukuthi amadivayisi asekelwe ku-Flash aqukethe i-ROM yokuqalisa amagama angu-256 ukuze kube lula ukuhlelwa kwe-in-circuit.Umndeni we-240xA uhlanganisa namadivayisi e-ROM ahambisana ngokugcwele nozakwabo be-Flash.
Wonke amadivaysi angu-240xA anikeza okungenani imojuli yomphathi womcimbi eyodwa eyenzelwe ukulawulwa kwezimoto zedijithali kanye nezinhlelo zokusebenza zokuguqula amandla.Amakhono ale mojula ahlanganisa isizukulwane se-PWM esimaphakathi kanye/noma esiqondaniswe emaphethelweni, i-deadband ehlelekayo ukuvimbela amaphutha adlula ukudubula, nokuguqulwa kokuvumelanisa kwe-analog-to-digital.Amadivayisi anabaphathi bemicimbi emibili anika amandla ukulawula kwezimoto eziningi kanye/noma isiguquli ngesilawuli esisodwa esingu-240xA DSP.Khetha amaphinikhodi e-EV anikezwe ngokujikeleza kwe-"input-qualifier", enciphisa ukucushwa kwephini ngokungazi ngamaphutha.
Ukusebenza okuphezulu, i-10-bit analog-to-digital converter (ADC) inesikhathi esincane sokuguqula esingu-375 ns futhi inikeza amashaneli afika kwangu-16 okufakwayo kwe-analog.Amandla wokulandelanisa okuzenzakalelayo we-ADC avumela ukuguqulwa okuphezulu okungu-16 kwenzeke ngeseshini eyodwa yokuguqulwa ngaphandle kwanoma iyiphi i-CPU ephezulu.
I-serial communications interface (SCI) ihlanganiswe kuwo wonke amadivaysi ukuze inikeze ukuxhumana okulinganayo kwamanye amadivaysi ohlelweni.Kumasistimu adinga ukuxhumana okungeziwe, i-2407A, 2406A, 2404A, kanye ne-2403A inikeza i-16-bit synchronous serial peripheral interface (SPI).I-2407A, 2406A, kanye ne-2403A inikeza imojuli yezokuxhumana yenethiwekhi yesilawuli (CAN) ehlangabezana nokucaciswa okungu-2.0B.Ukwandisa ukuguquguquka kwedivayisi, amaphinikhodi asebenzayo nawo angalungiseka njenge-General-purpose inputs/outputs (GPIOs).
Ukuze wenze lula isikhathi sokuthuthukisa, ukulingisa okusekelwe ku-JTAG okuthobelana nokuskena kuhlanganiswe kuwo wonke amadivayisi.Lokhu kunikeza amandla angaphazamisi esikhathi sangempela adingekayo ukuze kulungiswe amasistimu okulawula idijithali.Uhlu oluphelele lwamathuluzi okukhiqiza amakhodi kusukela kubahlanganisi C kuya embonini ye-Code Composer Studio™;olungisa iphutha weseka lo mndeni.Onjiniyela abaningi bezinkampani zangaphandle abanikezeli nje kuphela ngamathuluzi okuthuthukisa izinga ledivayisi, kodwa futhi nokuklanywa kweleveli yesistimu nosekelo lokuthuthukisa.
