EMERSON KJ3223X1-BA1軸向振動(dòng)探頭
框圖下圖是MVME7100架構(gòu)的框圖。處理器MVME71000設(shè)計(jì)用于支持MC864xD（雙e600核）處理器。處理器被配置為在1.067GHz或1.33GHz核心頻率下操作，具有相應(yīng)的DDR400MB或DDR533 DDR2內(nèi)存總線。MVME7100支持處理器復(fù)位配置的上電復(fù)位（POR）引腳采樣方法。當(dāng)復(fù)位被解除時(shí)，處理器上的各種配置引腳的狀態(tài)被采樣，以確定所需的操作模式。上拉和下拉電阻器的組合用于設(shè)置選項(xiàng)。有些選項(xiàng)是固定的，有些選項(xiàng)可以在構(gòu)建時(shí)通過安裝適當(dāng)?shù)纳侠?下拉電阻器來選擇。有關(guān)更多詳細(xì)信息和/或編程信息，請(qǐng)參閱第117頁附錄B“制造商文件相關(guān)文檔”中列出的MC864xD參考手冊(cè)。
Block Diagram The following figure is a block diagram of the MVME7100 architecture.Processor The MVME7100 is designed to support the MC864xD (dual e600 core) processor. The processor is configured to operate at 1.067GHz or 1.33GHz core frequency with a corresponding DDR400MB or DDR533 DDR2 memory bus. The MVME7100 supports the power-on reset (POR) pin sampling method for processor reset configuration. The states of the various configuration pins on the processor are sampled when reset is deasserted to determine the desired operating modes. Combinations of pull-up and pull-down resistors are used to set the options. Some options are fixed and some are selectable at build time by installing the proper pull-up/pull-down resistor. Refer to the MC864xD reference manual, listed in Appendix B, Related Documentation , Manufacturers’ Documents on page 117 for additional details and/or programming information.
