eMMC5.1

The embedded MultiMedia Card(eMMC) is the flash memory standard set by the MMC Association for mobile phones and tablets. It is an embedded multimedia memory card packaged into a BGA chip.

eMMC is made using parallel transmission technology. Although data reading and writing must be performed separately, it has the advantages of small size, low wiring difficulty, and high integration. eMMC is obviously different from other versions of MMC, because eMMC is not a card that users can move at will, but a permanent circuit board accessory. If eMMC has a problem with the memory or its controller, it may be necessary to replace the entire PCB (printed circuit board) to repair it.

Features :
– Support eMMC / MMC Trigger、Protocol Analyzer、Bus decodes (According to the optional model)
– 3-Pin Mode：If you only need to analyze the waveform data of CMD and BUSY, 3-Pin Mode will be a good choice. You do not need to connect all the pins in the measurement. You only need to connect the CLK, CMD, and D0 pins to measure the CMD data.
– No Clk Mode：If you need to record the CMD waveform data for a long time, you can ONLY connect CMD pin. Then you can do the CMD analysis with transitional storage.
