Nexperia NXS0506 SD 3.0-compatible memory card integrated auto-direction control and level translator with EMI filter and ESD protection 9.6. Pin and channel naming
The channel naming as shown in Fig. 2 and in the Pinning information (Section 8) aims at using NXS0506 for SD-card interfaces. The sequence of the channels is chosen to easily connect to SD-card connectors. As the internal design of channels DAT0 (pins DAT0A and DAT0B), DAT1 (pins DAT1A and DAT1B), DAT2 (pins DAT2A and DAT2B), DAT3 (pins DAT3A and DAT3B) and CMD (pins CMDA and CMDB) is identical, these channels can be exchanged. Swapping channels in the above mentioned group can help ease PCB layout issues. E.g. DAT0 can be swapped with DAT1 or DAT3 with CMD without impact on functionality of NXS0506.
