Kev piav qhia rau TMS320LF2407A
Cov khoom siv TMS320LF240xA thiab TMS320LC240xA, cov tswv cuab tshiab ntawm TMS320C24x™;tiam ntawm digital signal processor (DSP) controllers, yog ib feem ntawm TMS320C2000™;platform ntawm taag-point DSPs.Cov khoom siv 240xA muab cov kev txhim kho TMS320™;DSP architectural tsim ntawm C2xx core CPU rau tus nqi qis, qis zog, thiab kev ua haujlwm siab.Ob peb cov khoom siv siab tshaj plaws, ua kom zoo rau cov kev siv lub cev muaj zog thiab kev tswj xyuas cov lus tsa suab, tau muab kev koom ua ke los muab qhov tseeb ib leeg-chip DSP maub los.Thaum code-tshaj nrog C24x ™ uas twb muaj lawm;DSP maub los li qub, 240xA muaj kev ua haujlwm ntau ntxiv (40 MIPS) thiab qib siab dua ntawm kev sib koom ua ke.Saib TMS320x240xA Device Summary section rau cov cuab yeej tshwj xeeb.
240xA tiam muaj ib qho kev nco qhov ntau thiab tsawg thiab cov khoom siv sib txawv sib txawv kom ua tau raws li cov nqi tshwj xeeb / cov ntsiab lus ua tau zoo xav tau los ntawm ntau daim ntawv thov.Flash pab kiag li lawm txog li 32K cov lus muab cov nqi-zoo reprogrammable daws rau ntim ntau lawm.Cov 240xA cov khoom siv muaj tus password-raws li "code security" feature uas muaj txiaj ntsig zoo hauv kev tiv thaiv kev txwv tsis pub luam tawm ntawm tus tswv code khaws cia hauv on-chip Flash / ROM.Nco ntsoov tias Flash-raws li cov khoom siv muaj 256-lo lus khau raj ROM los pab txhawb kev ua haujlwm hauv-circuit.240xA tsev neeg kuj suav nrog ROM cov khoom siv uas muaj tag nrho tus pin-rau-tus pin sib xws nrog lawv cov Flash counterparts.
Tag nrho 240xA li muaj tsawg kawg yog ib qho kev tshwm sim tus thawj tswj module uas tau ua kom zoo rau cov kev tswj lub cev muaj zog thiab kev siv hluav taws xob hloov pauv.Lub peev xwm ntawm cov qauv no suav nrog qhov nruab nrab- thiab / lossis ntug-txhim kho PWM tiam, programmable deadband los tiv thaiv kev tua-los ntawm kev ua txhaum, thiab synchronized analog-rau-digital conversion.Cov khoom siv nrog ob tus thawj tswj hwm kev tshwm sim ua kom muaj ntau lub cev muaj zog thiab / lossis hloov pauv tswj nrog ib tus 240xA DSP maub los.Xaiv EV pins tau muab nrog "kev tsim nyog-tsim hluav taws xob" circuitry, uas txo qis qhov tsis pom zoo tus pin-ua los ntawm glitches.
Qhov kev ua tau zoo, 10-ntsis analog-rau-digital converter (ADC) muaj lub sijhawm hloov pauv yam tsawg kawg nkaus ntawm 375 ns thiab muaj txog 16 channels ntawm analog tawm tswv yim.Lub peev xwm autosequencing ntawm ADC tso cai rau qhov siab tshaj plaws ntawm 16 kev hloov pauv los ua qhov chaw hauv ib qho kev hloov pauv ib zaug yam tsis muaj CPU nyiaj siv ua haujlwm.
Lub serial kev sib txuas lus interface (SCI) yog kev koom ua ke ntawm txhua yam khoom siv los muab kev sib txuas lus asynchronous rau lwm cov khoom siv hauv lub cev.Rau cov tshuab uas xav tau kev sib txuas lus ntxiv, 2407A, 2406A, 2404A, thiab 2403A muab 16-ntsis synchronous serial peripheral interface (SPI).Lub 2407A, 2406A, thiab 2403A muab kev sib txuas lus hauv cheeb tsam (CAN) module uas ua tau raws li 2.0B specifications.Txhawm rau ua kom cov cuab yeej hloov tau yooj yim, cov pins ua haujlwm kuj tseem tuaj yeem kho tau raws li cov hom phiaj dav dav nkag / tawm (GPIOs).
Txhawm rau txhim kho lub sijhawm txhim kho, JTAG-raws li scan-based emulation tau muab tso rau hauv txhua yam khoom siv.Qhov no muab cov peev txheej uas tsis muaj kev cuam tshuam rau lub sijhawm tiag tiag uas yuav tsum tau ua kom debug cov kev tswj hwm digital.Kev ua tiav ntawm cov cuab yeej tsim los ntawm C compilers rau kev lag luam-tus qauv Code Composer Studio ™;debugger txhawb tsev neeg no.Ntau tus neeg thib peb tus tsim tawm tsis yog tsuas yog muab cov cuab yeej tsim kho theem, tab sis kuj tseem tsim qauv tsim thiab kev txhawb nqa.
