Faahfaahinta TMS320LF2407A
Qalabka TMS320LF240xA iyo TMS320LC240xA, xubnaha cusub ee TMS320C24x™;jiilka kontaroolayaasha signalada dhijitaalka ah (DSP), waa qayb ka mid ah TMS320C2000™;madal ee DSP-yada go'an.Aaladaha 240xA waxay bixiyaan TMS320 oo la xoojiyey;Naqshadaynta qaab dhismeedka DSP ee C2xx xudunta u ah CPU ee qiimo jaban, awood yar, iyo karti hawlqabad sare.Dhowr qaybood oo horumarsan, oo loo habeeyay mootada dhijitaalka ah iyo codsiyada xakamaynta dhaqdhaqaaqa, ayaa la isku daray si loo bixiyo kontaroolaha DSP-ga hal-chip ah oo run ah.Iyadoo kood ku habboon C24x™ jira;Aaladaha kontoroolka DSP, 240xA waxay bixisaa waxqabadka habaynta oo kordhay (40 MIPS) iyo heer sare oo is dhexgalka durugsan.Ka eeg qaybta TMS320x240xA Soo koobida Aaladda ee sifooyinka gaarka ah ee qalabka.
Jiilka 240xA waxa uu bixiyaa tiro badan oo cabbirro xusuusta ah iyo qaybo kala duwan oo loo habeeyey si ay u buuxiyaan qiimaha gaarka ah / dhibcaha waxqabadka ee looga baahan yahay codsiyo kala duwan.Aaladaha fiishka ee ilaa 32K kelmadood waxay bixiyaan kharash wax ku ool ah oo dib loogu habeyn karo wax soo saarka mugga.Aaladaha 240xA waxay bixiyaan sifada "code security" ku salaysan erayga sirta ah kaas oo faa'iido u leh ka hortagga nuqulka aan la ogolayn ee koodka lahaanshaha ee lagu kaydiyay Flash/ROM-ka.Ogsoonow in aaladaha Flash-ku-saleysan ay ka kooban yihiin 256-erey boot boot ROM ah si ay u fududeeyaan barnaamijyada wareegga gudaha.Qoyska 240xA waxa kale oo ka mid ah aaladaha ROM-ka oo si buuxda pin-to-pin ula jaan qaadaya dhiggooda Flash.
Dhammaan aaladaha 240xA waxay bixiyaan ugu yaraan hal module maamulaha dhacdada kaas oo loo habeeyay xakamaynta mootada dhijitaalka ah iyo codsiyada beddelka awoodda.Awoodaha cutubkan waxaa ka mid ah jiilka PWM ee xarunta-iyo/ama cidhif-ku-socda, bakhti-ku-tiirsanaanta barnaamijka si looga hortago khaladaadka-toogashada, iyo isu-beddelka is-beddelka-dijitaalka ah ee la-wada-jirka ah.Aaladaha leh maareeyayaasha dhacdooyinka laba-geesoodka ah waxay awood u siinayaan kontorool matoor badan iyo/ama beddeleyaal leh hal 240xA DSP kantaroole.Dooro biinanka EV ayaa la siiyay wareegga "qalliin-u-qalmitaanka", kaas oo yareeya-kicinta biinanka ee aan ku talagal ahayn ee cilladaha.
Waxqabadka sare, 10-bit analog-to-dijital Converter (ADC) wuxuu leeyahay wakhtiga beddelka ugu yar ee 375 ns wuxuuna bixiyaa ilaa 16 kanaal oo gelinta analoogga ah.Awooda iswada ee ADC waxay u ogolaanaysaa ugu badnaan 16 beddelaad in lagu qabto hal fadhi oo beddelaad ah iyada oo aan wax ka sarreeya CPU.
Isku-xidhka isgaadhsiinta taxan (SCI) ayaa lagu dhex daray dhammaan aaladaha si loo bixiyo isgaadhsiin aan kala sooc lahayn aaladaha kale ee nidaamka.Nidaamyada u baahan is-gaarsiinta dheeraadka ah ee isgaarsiinta, 2407A, 2406A, 2404A, iyo 2403A waxay bixiyaan 16-bit oo iskuxiran oo isku xiran oo isku xiran (SPI).2407A, 2406A, iyo 2403A waxay bixiyaan moduleka isgaarsiinta shabakada kontaroolaha (CAN) kaas oo buuxiya shuruudaha 2.0B.Si loo kordhiyo dabacsanaanta aaladda, biinanka shaqaynaaya ayaa sidoo kale loo habayn karaa sidii wax-soo-gelin/wax-soo-saar guud (GPIOs).
Si loo habeeyo wakhtiga horumarka, JTAG-ku dayashada ku-salaysan iskaanka ayaa lagu dhex daray dhammaan aaladaha.Tani waxay ku siinaysaa awood aan faragelin lahayn waqtiga-dhabta ah ee looga baahan yahay si loo tirtiro nidaamyada xakamaynta dhijitaalka ah.Qayb dhammaystiran oo ah aaladaha soo saarista koodka ee ka socda C compilers ilaa heerka-warshadaha Code-ka laxamiistaha Studio™;debugger ayaa taageera qoyskan.Tiro badan oo soo-saareyaal ah oo dhinac saddexaad ah kaliya ma bixiyaan qalabka horumarinta heerka-qalabka, laakiin sidoo kale qaabaynta heerka nidaamka iyo taageerada horumarinta.
