RTL8211D目前原廠停產(chǎn),不再主推。目前市場(chǎng)上購(gòu)買RTL8211D相對(duì)困難,RTL8211E可以pin to pin替換RTL8211D,替換對(duì)應(yīng)型號(hào)表格如下:
Part Number E系列 Package Part Number D系列 Package
RTL8211E-VB-CG 48-Pin QFN RTL8211D-VB-GR 48-Pin QFN
RTL8211E-VL-CG 48-Pin QFN 無對(duì)應(yīng)型號(hào)
RTL8211EG-VB-CG64-Pin QFN RTL8211DG-VB-GR 64-Pin QFN
無對(duì)應(yīng)型號(hào) RTL8211DN-VB-GR 88-Pin QFN
我們先從兩者的規(guī)格書來看其封裝和對(duì)應(yīng)的管腳功能。
下圖為RTL8211D 48-pin QFN封裝的管腳圖:
RTL8211E 48-pin QFN封裝的管腳圖如下:
從以上兩圖可以看出,RTL8211E在封裝和管腳上完全兼容RTL8211D。
從功能描述上看,此兩者有何差異了?以下是功能比較,僅對(duì)比有差異部分和細(xì)微差別部分。相同部分省略。
