1. RESET# or HOLD# signals can share Pin 7 with DQ3, depending on the selected device
(see Part Numbering Ordering Information). When using single and dual I/O commands
on these parts, DQ3 must be driven high by the host, or an external pull-up resistor must
be placed on the PCB, in order to avoid allowing the HOLD# or RESET# input to float.
Notes:
2. On the underside of the W-PDFN package, there is an exposed central pad that is pulled
internally to VSS. It can be left floating or can be connected to VSS. It must not be con-
nected to any other voltage or signal line on the PCB.
3. MT25QXXXXXXX8EXX-XXXX is not available on 8 pin package.
