SI2439開發(fā)板套件編程器的評估演示板及套件規(guī)格書PDF中文資料

SI2439屬于開發(fā)板套件編程器的評估演示板及套件。由美國思佳訊公司制造生產(chǎn)的SI2439評估和演示板及套件該系列產(chǎn)品提供了一種方便的方法，在經(jīng)過驗證的實施環(huán)境中評估某些重點器件的性能或特性。評估方法通常有完善的文檔說明，并且視乎具體情況由評估軟件提供支持。產(chǎn)品通常由印刷電路板組成，板上已裝有重點器件以及必要或有用的支持元器件，另外也可能包括其他組件，例如電纜或電源。對于數(shù)量特別多或類別獨特的器件類別(如 ADC、DAC 和開關模式電源)，評估平臺可組合為一個單獨的產(chǎn)品系列。
