Papiso ea lisebelisoa
Karolo ena e hlalosa liphapang le lintlha tsa hardware ha u tloha ho sesebelisoa sa MCXN ho ea ho MCXA.
Phapang ea sephutheloana / pinout
Sesebelisoa sa MCXN se fanoa ka likhetho tse peli tsa liphutheloana, e leng 100HLQFP le 184MAPBGA. Ka lehlakoreng le leng, sesebelisoa sa MCXA se fumaneha ka liphutheloana tse tharo, e leng 64LQFP, 48HVQFN, le 32HVQN. Lisebelisoa tsena ha lia etsetsoa hore li tsamaisane ka pin-to-pin. U ka fumana setšoantšo sa sephutheloana ho database ea Sesebelisoa.
Mehopolo e fokolang ea tsamaiso
Ho na le lintlha tsa tlatsetso tsa lisebelisoa ha u falla ho tloha MCXN ho ea MCXA.
Setšoantšo sa 3 se bontša bonyane tsamaiso ea MCXA.
Lisebelisoa tsa MCXN le MCXA li na le reset, ISP, le li-circuits tsa debug bakeng sa sistimi e fokolang. Leha ho le joalo, MCXA e kopanya LDO e bonolo e se nang cap ho matlafatsa mantlha potolohong ea phepelo ea motlakase, ha MCXN e fana ka converter e eketsehileng ea DCDC e nang le ts'ebetso e ntle ea matla. Ntle le moo, MCXA ha e na potoloho ea kristale ea 32 K ea kantle.

P: Na nka tsamaisa software ea ka ka kotloloho ho tloha MCXN ho ea MCXA ntle le liphetoho?
A: Che, ho falla lipakeng tsa MCXN le MCXA microcontrollers ho hloka liphetoho tsa hardware le software ho netefatsa tšebelisano le ts'ebetso e nepahetseng.
P: Nka khetha joang nomoro ea karolo e nepahetseng ea MCXA bakeng sa projeke ea ka?
K: Sebedisa dekhoutara e fanoeng bukeng ya mosebedisi ho utlwisisa moelelo wa dinomoro tsa karolo mme o kgethe ho latela ditlhoko tsa hao tsa saese ya flash, SRAM, core speed, le mofuta wa sephutheloana.
P: Nka fumana linomoro tsa morao-rao tse rekoang tsa MCXA hokae?
A: Etela https://www.nxp.com ho etsa patlo ea karolo ea nomoro le ho netefatsa boteng ba hona joale ba linomoro tsa likarolo tse hlophisehang.
